Title: Conveying device
Inventor: KATSUKI SATOSHI
IPC: B65G17/20
Filed: 1985-07-15
Abstract: PURPOSE:To make a body drop ever so easy, by installing a detecting shaft coming into contact with the body supported by a holding device and constituting it so as to detect the presence of the body with the signal, in case of a conveying device for picture tube parts such as a cathode-ray tube and so on. CONSTITUTION:One end of a detecting shaft 30 comes into contact with a panel 6 by dint of spring force of a spring 31, whereby this detecting shaft is pushed upward, and the other end approaches in a noncontact manner and detected by a detector 32, thereby detecting the presence of the panel 6. When the panel 6 drops, the detecting shaft 30 goes down to a lower part. The detector 32 detects this motion and informs an operator. With this constitution, detection of a body drop becomes so easy.

Title: Phosphoric electrolyte fuel cell
Inventor: TAKAGI YASUO
IPC: H01M8/02
Filed: 1982-09-10
Abstract: PURPOSE:To lengthen service life by providing air-tight resin layers at the ends of a pair of electrodes thereby preventing crossover phenomena at the end of a cell. CONSTITUTION:Air-tight resin layers are provided at the ends of a pair of electrodes 6a, 6b. For example, paper electrodes 6a, 6b made of carbon fiber are provided on both faces of an electrolyte layer 5 where silicon carbide powder is impregnated with phosphoric acid solution to constitute a unit cell 11. Then heat resistant and acid resistant resin is impregnated to the end section 10 of the electrode 6a to be adhered through a rubber insulator 7 and an adhesive tape 8. Since the end section of the electrode will never pass gas, even when a gap is produced between the insulator and the electrolyte layer through expansion due to the operating cycle of cell, gas will never pass to the opposite side of the electrode thus to prevent crossover.

Title: Synchronizing signal circuit
Inventor: KOMORI TOSHIO
IPC: H04N5/12
Filed: 1980-11-06
Abstract: PURPOSE:To reduce the disturbance of the synchronization of a PLL circuit to shorten the restoration time, by providing a monostable multivibrator which detects the drop-out of an input synchronizing signal and by supplying substitutional pulses to the PLL circuit at the drop-out detection time. CONSTITUTION:When an input synchronizing signal is dropped out, a monostable multivibrator 1 is inverted, and this state is sent to a differentiating circuit 2. The differentiating circuit 2 differentiates the rise part of the monostable multivibrator 1 and sends the result to a waveform shaping circuit 3. The output of the waveform shaping circuit 3 is supplied to an OR circuit 4 together with a horizontal synchronizing signal, and they are added to interpolate the dropped-out horizontal synchronizing signal. Consequently, since horizontal synchronizing pulses without drop-out are supplied to a PLL circuit 5, the disturbance of synchronization of the PLL circuit is reduced, and the restoration time for the disturbance is shortened.

IPC: G06F9/38
Filed: 1988-06-27
Abstract: PURPOSE:To execute the parallel operation without being conscious of the interference between plural arithmetic units by simultaneously processing plural instructions and writing the processing result into one shared register. CONSTITUTION:First, the instruction of an address shown by a program counter is taken out from an instruction memory and the instruction memory can simultaneously take out two instructions. The read instruction is once fetched into an instruction buffer. An instruction interpreting part interprets respective instructions and prepares the instruction for an arithmetic part and a register file. The arithmetic part executes the operation to the data from the register file and stores it into the register file. Consequently, in a next instruction, the result can be used even by any arithmetic units and it is not necessary to be conscious of the interference between plural arithmetic units.
