Title: Film frame feed controller
Inventor: AKIYAMA KAZUHIRO
IPC: G03B17/00
Filed: 1981-03-02
Abstract: PURPOSE:To carry out the assured engagement and its release between a control cam and a control lever, by providing an interlocking lever between the control lever and a shutter driving lever and connecting the interlocking lever to the control lever via a spring. CONSTITUTION:An interlocking lever 71 is provided between a shutter driving lever 70 and a control lever 65. When the lever 71 has a shift in response to the right shift of the lever 70, the lever 65 is brought into contact with a control cam 47 by the force of a spring 67 hooked between the levers 71 and 65. At the same time, a film frame feeding switch S3 is switched from a cintact (a) to a contact (b) to stop the revolution of a motor. When the lever 70 has the left shift, the lever 71 is reset by the force of a spring 72. In this case, the lever 65 is pushed to be reset. In such constitution, the engagement and its release are carried out assuredly between the lever 65 and the cam 47.

Title: Induction motor speed controller by liquid resistors
Inventor: NAKAGOME NORIYUKI
IPC: H02P23/00
Filed: 1978-03-15
Abstract: PURPOSE: To control the speed free of hunting by adjusting the electrode of a liquid resistor which is connected to the secondary winding of an induction motor by a fluid pressur powere cylinder according to both the actual speed of the detected induction motor and the deviation signal of the speed command.  
     CONSTITUTION: When the breaker 2 turns ON, the rotation of the winding type induction motor 3 increases to the speed which is equal to the resistance value of the liquid resistor 4 and the speed is detected by the pilot generator 7. The deviation signal with the speed command value 8 is converted into air pressure signals by the power to air converter 15 and transmitted to the power cylinder 16 from the comparator 9 through the proportional integrator 14. The power cylinder 16 shifts the output shaft to the position which is proportional to the signal and adjusts the electrode of the liquid resistor 4. When the speed command value 8 is larger than feedback signals, the output signal of the proportional integrator 14 increases and the resistance value of the liquid resistor 4 decreases. The speed of the induction motor 3 increases in such a case, but it decreases when contrary. When the operation time of the power cylinder 16 is arbitrarily adjusted in conformity with load, it finally matches the speed command 8 and the electrode operation stops.

Title: Controlling system of power supply
Inventor: FUJITA MASAAKI
IPC: G06F1/26
Filed: 1982-02-23
Abstract: PURPOSE:To simplify the constitution of a power supply circuit of a system having a simplified structure and driving system, by using a storage element, a relay or semiconductor switch element which is not normal self-support type and a control circuit. CONSTITUTION:When a power supply switch C is turned on, a reset pulse generating circuit 5 generates a reset pulse E by the output voltage F of a power supply 4 of the control part. A control circuit 2 starts its operation when the pulse E is changed to a high level from a low level after the voltage F is applied. In this case, a power supply circuit 9 of a part B to be controlled is controlled by a power supply switch 7, and a control signal G is applied from the circuit 2. The self-supporting action of the switch 7 is performed through the circuit 2 and a nonvolatile memory 3. When the electric power H of the input side of the switch 7 is cut off, the circuit 2 is reset to its initial state by the pulse E when the power H is applied later. Thus the switch 7 is kept at a state set before the power H is cut off.

Title: Optical demultiplexer
Inventor: IKEDA MASAHIRO
IPC: H01S5/12
Filed: 1984-02-21
Abstract: PURPOSE:To make demultiplexing without insertion loss, easy integration, easy tuning of a center wavelength, etc. possible by using a grating due to a p-n junction waveguide to which a current lower than an oscillation threshold is charged. CONSTITUTION:When the charging current is flowed in the forward direction to a p-n junction wavelength having a periodic structure LAMBDA=lambda0/2N (N is an equivalent refractive index), an inverted distribution of electrons and positive holes due to a carrier is formed, and the waveguide 1 becomes a gain medium. Consequently, if signal lights having wavelengths lambda1, lambda2...lambda0...lambdan are made incident while keeping the charging current lower than the oscillation threshold, only the wavelength lambda0 is amplified and reflected, and signal lights having the other wavelengths pass through because their phases do not coincide with the phase of the grating period. The reflected signal light having the wavelength lambda0 is demultiplexed by a beam splitter 4 and is discharged. When the charging current is changed, the refractive index is changed by the carrier, and thereby, the center wavelength is changed.
