Title: Method and device for dispersion compensation
Inventor: OKAYAMA HIDEAKI
IPC: G02F1/125
Filed: 1994-10-24
Abstract: PURPOSE: To provide a dispersion compensator capable of easily compensating the wavelength dispersion of an optical signal. CONSTITUTION: The optical signal with wavelength nearest to specific wavelength λM mode-converted by a TE/TM mode conversion element 16 and provided with center wavelength λ0 on a long wavelength side slightly longer than the specific wavelength λM is inputted to the TE/TM mode conversion element 16. The shorter the wavelength (as approaching the specific wavelength), the larger the angle of rotation of a polarization plane (ratio of rotation is increased) on the long wavelength side of the specific wavelength λM. Therefore, the optical signal is provided with the rate of rotation depending on the wavelength. Delay depending on the angle of rotation of the polarization plane can be generated by propagating a polarized wave preservation optical fiber 12 connected to the output terminal 16b of the conversion element 10.

Title: Control device for brushless motor
Inventor: SATO YUTAKA
IPC: H02P6/06
Filed: 1999-09-13
Abstract: PROBLEM TO BE SOLVED: To reduce noise and improve efficiency with sinusoidal drive by calculating a phase according to the specific single output of a plurality of position sensors or entire output, when the fluctuation of a time interval is at a prescribed value or smaller, or at a prescribed value or larger. SOLUTION: Constant-speed mode or acceleration/deceleration mode determination is made from a position sensor mounted to a U phase, for example, in mode determination 19. Phase operation 17 calculates a phase θ of the induced voltage of U phase, according to the output signal of a position sensor 20 based on the determination result of the mode determination 19. For example, Hu, Hv, and Hw indicate a position detection signal that is the output signal of a Hall IC. The mode determination 19 measures the signal interval of Hu and determines that the mode is the constant-speed mode and the acceleration/ deceleration mode when the change in the signal interval is equal to a prescribed value or less, and equal to a prescribed value or more, respectively. A phase operation means 17 calculates the phase based on the mode determination.  More specifically, only one position sensor and all signals are used at a constant speed and acceleration modes, respectively, thus reducing the deviation between an operation phase and an actual phase.

Title: Shift register
Inventor: AKIYAMA KAZUHIRO
IPC: G11C19/00
Filed: 1988-10-13
Abstract: PURPOSE:To stably hold data even in a long data holding cycle by adding a multiplexer to a dynamic latch. CONSTITUTION:In each of memory cells 1 - 4, the clocked inverters 12 and 13 are successively connected to a 2-input multiplexer 11 which uses the external input as the 1st input and driven by the clocks phi1 and phi2 respectively. Then the output Q of the inverter 13 is acquired at a terminal 10 and supplied to the 2nd input of the multiplexer 11. Both inverters 12 and 13 form a dynamic latch, and the multiplexer 11 selects the data on the J0 side when a shift control signal 6 supplied from a terminal 6 is kept at 'L' and then selects the data on the J1 side when the signal 6 is kept at 'H' to output these data to the dynamic latches 12 and 13. In other words, the multiplexer 11 fetches the external data in a period I and otherwise circulates its own data to stabilize a dynamic holding state. Then the multiplexer 11 outputs the data to the cell of the next stage in the second period I and fetches the output of the preceding stage. In such a constitution, the data can be held stably even in a long data holding cycle.

Title: Two-wavelength light source element
Inventor: NANAMI MASAYA
IPC: G02B6/122
Filed: 1990-09-27
Abstract: PURPOSE:To eliminate an unrequired diffractive function on two parallel rays and two surface elastic waves that exist on a piezoelectric substrate, to efficiently receive frequency shift, and to reduce influence due to an unrequired surface elastic wave by utilizing the Bragg angle. CONSTITUTION:Light with frequency fo is made incident on a plane type optical waveguide 3. The parallel rays 13 are generated at a first thin film lens 4, and also, the parallel rays 14 are generated at a second lens 5. The frequency modulation of the light is performed by applying a sine wave signal with excitation frequency f1 to a first cross-finger type electrode 6 and making a generated first surface elastic wave 15 incident on the parallel rays 13 at the Bragg angle thetaB in a state where the rays 13, 14 exist. Similarly, a second surface elastic wave 16 performs the frequency modulation of the light. First modulated light is converged on a third thin film lens 8, and is waveguided to a first light emission point 17. In other words, the light goes to the one with frequency fo+f1 by receiving the frequency shift by f1. Also, second modulated light goes to the one with frequency fo+f2. Also, angle relation by which no diffractive function is applied can be set by setting the aperture angle of the light 13 and 14 so as to be equal to the Bragg angle. Thereby, it is possible to realize a two-wavelength light source element utilizing the Bragg diffraction of the light.

Abstract: PURPOSE:To enable the use of any kind of an actuator by a method wherein a housing to contain a heat generating drive source having an output shaft in a sealing manner is provided, and a sealing means is mounted to the portion, through which an output shaft is extended, of the housing. CONSTITUTION:The interior of a housing to contain a heat generating drive source in a sealing manner is managed to approximate an atmospheric pressure (760Torr) in He by means of a pressure gauge 22.

A material of the motor 10 can be used without being limited to a material used as a vacuum part. Thus, the motor 10 can be used as an actuator in special environment without improving a good on a market. In this case, the portion, through which an output shaft is extended, of the housing is sealed with an O-ring seal 16.

IPC: H01L21/3063
Filed: 1984-12-10
Abstract: PURPOSE:To execute fine process to an Si substrate by utilizing a phenomenon where passive potential changes depending on impurity concentration of Si. CONSTITUTION:An Si substrate is immersed into the KOH aqueous solution 2 in a reservoir 1, an electrode 4 is attached to a high impurity concentration part 3b and a power supply 6 is provided between said electrode and Pt electrode 5. When a positive potential is applied to the Si substrate for the potential of liquid, a current flowing to electrode 4   high concentration part 3b  liquid 2 increases and an SiOx is formed on the substrate surface. When SiOx is deposited quicker than the etching of SiOx by KOH, the Si substrate becomes passive. Therefore, when a voltage of a certain level is applied, SiOx film is not formed on the low impurity concentration part 3a but on the high impurity concentration part 3b. According to this structure, a degree of freedom in selective etching of Si is remarkably enlarged and complicated and fine processing can be attained.
