Title: Optical branching and coupling device
Inventor: OKADA HIROSHI
IPC: G02B6/28
Filed: 1986-12-19
Abstract: PURPOSE:To obtain a branching and coupling device which is easily formed by forming optical fiber holding guide holes at proper angles to fitting surfaces of respective blocks obtained by dividing a housing by N, and coupling end parts of both optical fibers optically with each other when blocks are fitted together. CONSTITUTION:An optical fiber 3 is inserted into two divided housing components 1 and 2, and an insertion hole end 2 is projected slightly from the housing; and the fiber 3 is cut and fixed at a position projected slightly from a corner of the housing and the insertion hole end 22 is made to abut on a metallic plate 4 which has a right-angled surface heated by a heater. The plastic optical fiber 3, therefore, deforms plastically and the part projecting from the housing components is absorbed principally by a chambered part. Then the heater 5 is detached from the metallic plate 4, the fiber end surface is cooled, and the metallic plate 4 and housing are detached, so that a right- angled end surface which is a specular surface is formed. The two components which are formed as mentioned above are combined together to easily from the branching and coupling device.

Title: Pwm controller for single-phase motor
Inventor: HASHINO SOUJIROU
IPC: H02P27/08
Filed: 1990-11-09
Abstract: PURPOSE:To control the number of revolutions continuously and in a stepless manner by providing four transistors constituting a power inverter, by inputting a constant voltage as a control signal and converting the voltage into frequency, by modulating a pulse signal through a PWM control system and by transmitting a control signal to the base of each transistor. CONSTITUTION:A control signal is first inputted as voltage value to a comparator 21 functioning also as buffer and amplifier and converted from voltage into frequency by V/F converter 32. Subsequently, a PWM signal is generated in a PWM converter 23 so that a pulse width modulation is conducted, and the modulation frequency by the modulation is transmitted to the base of four transistors 12A-12D so that a predetermined switching action is conducted. Because a voltage supplied to a motor 15 is constant, the number of revolutions of the motor changes and can be controlled continuously and in a stepless manner when frequency changes. Also, even if the number of revolutions is lowered, a torque is prevented from dropping so that the motor never stops, because the voltage is constant.

Filed: 1996-11-14
Abstract: PROBLEM TO BE SOLVED: To generate intermodulation distortion required for the intermodulation distortion compensation circuit with a superior characteristic through the configuration of easy adjustment. SOLUTION: An input frequency multiplex signal is distributed into two at a distributer 3a, so as to be opposite in phase to each other, each distribution signal is led out via composite diodes 4a whose characteristics are the same, and the distribution signals are synthesized by a synthesizer 3b using a balun transformer to produce odd number degree intermodulation distortion component in the synthesis output. Otherwise, the frequency multiplex signal is distributed into two, so as to be opposite in phase to each other. Each distribution signal is led out via composite diodes 4a whose characteristic are the same, and the distribution signals are synthesized by a resistance synthesizer 7a, so as to produce even number degree intermodulation distortion component in the synthesis output.  Since odd number and even number degree produce odd number degree intermodulation distortion components are obtained with high accuracy, the distortion components are mixed in an input frequency multiplex signal to eliminate the distortion components included in the input signal.

Title: Level holding circuit
Inventor: OTSUKA MARIKO
IPC: H03K19/0175
Filed: 1988-11-30
Abstract: PURPOSE:To prevent an unnecessary transient current from flowing in a gate and to reduce a consumption current by holding the voltage level of wiring to the same level as the output voltage of plural transfer gates. CONSTITUTION:When either of the transfer gates 3 and 4 is turned on, the voltage in the same level as the output is outputted from a second invertor 8b. When both transfer gates 3 and 4 are turned on from such a state, the voltage level of wiring 9 is held in a previous state. Thus, an input for a gate 6 connected to the output terminal is fixed, and the transient current is prevented from flowing. When either of the transfer gates 3 and 4 is turned on, the voltage level of wiring 9 is fixed to the same level as the output voltage level of the transfer gates 3 and 4. Thus, the transient current is prevented from flowing in a level holding circuit 8.

Title: Bit serial error correcting and decoding device
Inventor: SHIMADA MICHIO
IPC: H04L1/00
Filed: 1986-12-22
Abstract: PURPOSE:To attain decoding at high speed even if the bit length of an information symbol becomes longer by searching the tolerance of the information symbol in a bit unit and sequentially estimating the bit expression of the information symbol. CONSTITUTION:A reception signal is inputted to a register 112 and a state holding circuit 102 through an input buffer 111. While a sequential decoding control circuit 115 judges that a past estimation is correct, it shifts the content of the state holding circuit 102 and outputs it to a buffer 114. When said circuit 115 judges that the estimation is wrong and returns the state of a decoder to that of the past, it takes out a bit inputted to the buffer 114, holds it to the state holding circuit 102 and simultaneously holds the reception signal inputted to a buffer 113 in the past in the register 112. The estimated value of the information bit, namely, a decoded result is accumulated in the buffer 114 and the decoded result is outputted from an output terminal 104.

Title: Operation of fuel cell power generating system
Inventor: MIZUNO YUTAKA
IPC: H01M8/06
Filed: 1986-12-22
Abstract: PURPOSE:To make a system compact and to make safety operation possible by excessively supplying hydrogen to a cell from a reformer compared with that consumed for power generation, and burning only hydrogen produced in a reforming reaction in the reformer. CONSTITUTION:During normal operation, only hydrogen produced in a reforming reaction is used as fuel of a reformer 2 without supply of fuel from a separate fuel supply source. Therefore, a fuel supply unit having large capacity and its attachment are unnecessary and a system is made compact. Since excess hydrogen is constantly supplied to a cell 3, even when sudden load variation arises, a system can quickly respond by only increasing utilization. Therefore, the steady operation of the system is constantly obtained.
