Title: Piezoelectric vibration gyro, its support structure, and multi-dimensional gyro
Inventor: KURODA TATSUYA
IPC: G01C19/56
Filed: 1994-08-30
Abstract: PURPOSE: To provide a piezoelectric vibration gyro and support structure suited for miniaturization and thinning by reducing the restriction in assembly position and the man labor for assembly. CONSTITUTION: Electrodes 14, 16, and 18 for drive are formed on the outer- periphery side surface of an annular piezoelectric vibrator 12 of a vibration gyro 10 and common electrodes 20 and 22 are formed on the upper/lower surface sides. The piezoelectric vibrator 12 commonly connects the electrodes 14, 16, and 18 for drive to the plus side of a power supply for polarization and the common electrodes 20 and 22 are commonly connected to the minus side of the power supply for polarization and a voltage is applied, thus achieving polarization in a direction crossing the peripheral direction. Normally, the piezoelectric vibrator 12 is excited in a direction for connecting the electrode 14 and the electrodes 16 and 18 and in a direction for crossing the direction.  When an angular velocity is applied, coriolis force is applied to the direction for crossing the direction of the angular velocity. The angular velocity is differentially detected from the output of the electrodes 16 and 18.

Title: Fm modulator
Inventor: MIZUGUCHI NOBUAKI
IPC: H03C3/00
Filed: 1987-09-11
Abstract: PURPOSE:To obtain a signal subject to FM modulation very easily by varying the phase of a carrier signal inputted through the use of a variable delay device, and using the amplitude limit so as to eliminate the AM component of the signal. CONSTITUTION:An oscillator 1 consists of a logic gate and a crystal oscillator or the like and a stable carrier signal (a) is outputted. The variable delay device 2 consists of plural stages of logic gates in series and a power line is used as a control terminal 3. In keeping the control terminal 3 at a constant voltage, a constant delay device is obtained and an output delay time is changed in response to the voltage change. In giving a modulation signal (b) to the control terminal 3, the carrier signal (a) is outputted as the modulated signal (c). Since the power line of the logic gate is used as the control terminal 3 and the power voltage is changed, the signal (c) is subject to Am modulation simultaneously and the amplitude is changed. The amplitude limiter 4 eliminates the AM component from the signal (c) to shape the waveform and the FM modulation signal (d) is outputted. Thus, the FM modulator constituted entirely by logic gates only is realized simply and no adjustment is required.

IPC: H01L21/308
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To provide a method which facilitates the control of the shape of etching and prevents a deposit from being generated in an etching of a III-VI compound semiconductor, specially an MgXZn1- XSYSe1- Y (0<=X<1, 0<=Y<1).

IPC: B60W10/101
Filed: 1997-08-27
Abstract: PROBLEM TO BE SOLVED: To restrain a car speed deviation when the driving force is saturated, and quickly converge on a target car speed when it returns to the normal load condition by limiting the driving force command value input to a disturbance estimating means. SOLUTION: The operation for a part corresponding to a model matching compensator C3(z<-1> ) is performed to obtain a driving command value y4 for accelerating the actual car speed Vsp to the car speed command value Vspr. The operation for a part corresponding to robust compensator C2(z<-1> ) is performed to back-calculate the driving force y3 subjected to the influence of disturbance of the actual car speed Vsr. The driving force command value y4 is corrected by a running resistance estimated value Fr to obtain the final drive command value y1 (k). Secondly, the final drive command value y1 is limited within the upper and lower limit values. In the case where an engine torque saturation flag and the shift down saturation flag are both set, limit processing is conducted for the final driving force command value y1 (k) to obtain the input y5(k) of a disturbance estimating device.  Further the operation for a part corresponding to the compensator C1(z<-1> ) is executed.

Title: Method for driving weaving machine and device therefor
Inventor: NIIMURA TERUMI
IPC: D03D51/12
Filed: 1998-08-17
Abstract: PROBLEM TO BE SOLVED: To solve the occurrence of weaving bars that are caused by insufficient beating power on the start of weaving. SOLUTION: When a weaving machine is driven, the machine is allowed to start with the commercial power source at a larger rotation number than that of the steady rotation to effect the beating, then the weaving machine is reduced in its rotation with the output of the inverter toward the steady rotation. Thus, the beating power is increased at the start whereby the occurrence of weaving bars is inhibited.
