Release of Spherical Roller Bearing for use in Vibration Machinery by NSK

NSK has developed long lasting spherical roller bearings to be used in vibration machinery at mining facilities. The durability of newly released roller bearing has been made possible through special groove that has been created on the raceway of the outer ring for controlling the slippage action of the rollers. In addition to this, the curvature factor between the raceway and spherical roller has been optimized, resulting in reduced slippage and the accompanying initiation stress between the roller and the contact surfaces of the outer and inner ring raceways. 

Development of a New Fabric-type Gas Diffusion Layer for use in Fuel Cell

Toho Tenax Co. Ltd., part of the TeijinGroup Company, specializing in carbon fiber business has announced the development of a new fiber-type gas diffusion layer (GDL) to be used as an electrode component for fuel cell. The newly developed GDL is made of carbon fiber fabric exhibiting better flexibility and strength than currently used paper-type GDLs. The new GDL can be manufactured through roll-to-roll processing at a high speed resulting in reduction in user costs. The new GDL can provide a higher output for the fuel cell, thanks to better water permeability. 

Introduction of 8-pin SIM Card Connector for Mobile Phones and Vehicle Navigation System

Alps Electric has introduced a new SCGC1B03 Series, an 8-pin SIM card connector targeted to be used in mobile phones as well as car navigation systems. The new SIM card connector is industry’s first connector capable of automatically locking the card in when inserted to prevent accidental ejection. For ejecting the card the user simply pushes the card a second time. Furthermore, the new series prevents improper card insertion as the card can not be fully inserted if it’s oriented incorrectly. Featuring a compact size of 18.44mm (W) x 29.0mm (L) x 1.55mm (H), the new connector is the answer to challenge of limited space inside of the navigation system. Read 
Introduction of New Single-Chip 8-bit MCU featuring Embedded FRAM Memory by Fujitsu

Fujitsu Semiconductor has announced release of a new 8-bit MCU featuring embedded Ferroelectric Random Access Memory (FRAM) designed for variety of general purpose applications, such as consumer electronic products, healthcare as well as industrial systems. Incorporating the FRAM into the MCU will significantly reduces the footprint and cost through a simplified design eliminating chip-to-chip interconnects, resulting in improvement in transaction speed and internal bus interface between MCU and memory, out performing the FLASH or EEPROM. The embedded FRAM can be erased and rewritten 1015 times, with data retention of 10 years. The FRAM can be partitioned as either ROM or RAM. The new MCU MB95R203A operates with power supplies ranging from 1.8V to 3.6V, a power supplies that are typically used in home healthcare devices, such as blood pressure and glucose meters. The new chip incorporates timers and communication functions, as well as high-precision A/C converters, UART, I2C, and 16 I/O ports. Read more

Newly Developed Electromagnetic Noise Suppression Sheet by TDK-EPC

Capable of attenuating noise at high frequencies from 10 MHz to 3 GHz, the newly developed Flexield families of IRJH3 magnetic sheet by TDK-EPC were made, by combining original soft magnetic materials and polymer materials in creating a magnetic powder. The new magnetic sheets are ideal for use in noise countermeasure applications in mobile electronic devices such as mobile phones, digital still cameras, digital video cameras as well as other consumer electronic products. 

Development of Two New Power Semiconductor Devices for DC/DC Converter Application by Renesas Electronics

Renesas Electronics has introduced two new ultra compact package power semiconductor devices namely RJK0222DNS and RJK0223DNS to be used for DC/DC converters which provide power to CPU, memory, as well as other circuit blocks of products including servers and notebook PCs. Integrating a pair of power MOSFETs in to a single package, results in design of DC/DC converters that are both compact and offer higher mounting density.

Development of “Emboss Look 3D” a New Surface Processing Technology by Toppan Printing

Toppan Printing has developed a printing technology that makes a 3D design possible by giving a sense of depth to a paper carton packages. Through use of this new technology it is possible to produce visual effects such as sense of dept during the printing process. This has been achieved through use of UV varnish to form a microlens on top of fine dot pattern printing and optimizing the alignment of the lens. The new “Emboss Look 3D” technology eliminates any needs for special lens-shaped film, as well as eliminating any needs for separate process, where the 3D design can be produced with the use of regular printing process, a great cost saving.
Development of Projection-Type Electrostatic Capacitance Touch Panel by Hitachi Display

Widely use of touch panels both in smart phone and digital cameras will continue to play an important role in maintaining the high growth rate of this technology. Recently, the projection type electrostatic capacitance touch panels are gaining in popularity for allowing only a very light touch, not mentioning their multi-touch operations capability. Up to now, the projection-type electrostatic capacitance touch-panels produced a mild electric current on the surface of the LCD, where it detects changes in the electric current to determine where the user’s fingers is touching the display. However, in such scenario, non-conductive objects such a plastic stylus or a gloved hand could not be used since they have no effect on electric current. To overcome this, Hitachi Display has developed a projective-type electrostatic capacitance touch-panel capable of converting input from a non-conductive object into electrostatic capacitance, allowing use of plastic stylus and gloved hands or other similar objects on this type of display. The new technology is capable of detecting both conductive as well as non-conductive objects, all without compromising responsiveness to light touch or design considerations
