| 20120007039 | CRYSTAL GROWTH METHOD AND SEMICONDUCTOR DEVICE - A method of crystal growth is provided which can suppress development of dislocations and cracks and a warp in a substrate. The method of crystal growth of a group III nitride semiconductor has: a step of heating a silicon substrate; and a step of forming a depressed structure on the substrate surface by advance-feeding onto the heated silicon substrate a gas containing at least TMA (trimethylaluminum). | 01-12-2012 |
| 20110207297 | Method for Manufacturing Chalcopyrite Film - A highly safe method of obtaining chalcopyrite film wherein a Ib group metal and IIIb group metal are sufficiently combined with a VIb group element by only heat treatment without using an atmosphere containing a VIb group element (Se, S, Te). | 08-25-2011 |
| 20110012694 | RESONATOR AND RESONATOR ARRAY - [Subject] An object of the present invention is to provide a resonator readily achieving a high resonance frequency without extreme downsizing and allowing for a high Q factor. | 01-20-2011 |
| 20100327993 | MICRO MECHANICAL RESONATOR - A micro mechanical resonator includes a high dielectric substrate, and a torsional vibrator having one end that is a fixed end fixed to high dielectric substrate, and having the other end that is a free end. The torsional vibrator has a substantially circular plate-like shape, has a lower surface serving as the fixed end fixed to the substrate, and has an upper surface serving as the free end that is not fixed. The torsional vibrator torsionally vibrates relative to an axis (torsional vibration axis) connecting the center of the circle of the end surface of the fixed end to the center of the circle of the end surface of the free end. In this way, a micro mechanical resonator can be implemented which can be manufactured readily and achieves a high Q factor. | 12-30-2010 |
| 20100105992 | Pressure-sensitive conductive yarn and biological information-measuring garment | 04-29-2010 |
| 20090314062 | Fluid Actuator, and Heat Generating Device and Analysis Device Using the Same - A fluid actuator includes a piezoelectric body ( | 12-24-2009 |
| 20090101821 | Infrared Array Sensor - There is provided an infrared array sensor, which is capable of positional specification and flow tracking of an object to be detected without performing image processing, and whose cost is low. An infrared array sensor | 04-23-2009 |
| 20080278789 | VARIABLE SHAPE MIRROR AND OPTICAL PICKUP DEVICE - In a variable shape mirror including a base substrate; a mirror with a mirror surface; a fixed part, arranged on the base substrate, for fixing the mirror and the base substrate; and an actuator using a piezoelectric ceramics arranged between the base substrate and the mirror; an initial voltage of the actuator is a negative voltage. The initial voltage differs for each actuator; and is larger than or equal to a voltage at which a displacement of the actuator becomes minimum and smaller than zero voltage. The negative initial voltage is a bias voltage, and a voltage stroke is performed while applying the bias voltage. | 11-13-2008 |
