Title: Oil recovering system
Inventor: TERASAKI MASATOSHI
IPC: F04D29/06
Filed: 1983-02-28
Abstract: PURPOSE:To make it possible to reduce cost and an occupied space, and simplify pipings, by substituting a single oil separator for conventional dual oil separators connected through pipings to a gas chamber on suction side and an atmospheric gas chamber on back side. CONSTITUTION:A leaked oil in a gas chamber 10 on suction side and an atmospheric gas chamber 12 on back side is communicated through respective pipings 24 and 25 to a single oil separator 15. Orifices 26 and 27 are arranged in the pipings 24 and 25, respectively, so as to adjust the leaked oil and flow of suction gas and always hold pressure differential among the gas chamber 10 on suction side, the atmospheric gas chamber 12 on back side and the oil separator 15. The leaked oil and flow of suction gas are always directed to the oil separator 15, and oil separated in the oil separator 15 is returned to an oil tank 16, while separated gas is returned to a suction side of an initial stage impeller. In this manner, a single oil separator is substituted for conventional dual oil separators, thus reducing cost and an occupied space and simplifying pipings.

Title: Parallel processing system
Inventor: FUJIOKA SHIGEO
IPC: G06F11/30
Filed: 1989-02-08
Abstract: PURPOSE:To facilitate the debugging work in a lock state by executing an interruption processing at the time when a timer does not receive an ID number within a prescribed time, and executing the interruption processing at the time when a counter receives continuously the ID number by a prescribed number of times or more. CONSTITUTION:When a dead lock state is generated, the system becomes a waiting state in one sequential processing routine, the execution of its subsequent processing stops, and since an instruction for resetting a timer 1 is not executed within a prescribed time, an interruption from the timer 1 is generated, and the generation of the dead lock state can be detected. In such a way, the watch dog timer 1 and a counter 3 are integrated into a program for executing a debugging work. As a result, when a lock state is generated, a dead lock state can be detected and discriminated by output signals of the watch dog timer 1 and the counter 3. Also, when a lock state is generated, a processing routine 2 in which the lock state is generated can be known.

IPC: G11B7/0037
Filed: 1995-02-20
Abstract: PURPOSE: To correctly reproduce an information signal even when an error is generated beyond the ability of an error correcting code and to enhance the error correcting ability over plural sectors without increasing any parity sectors. CONSTITUTION: In an information recording block consisting of N tracks and N sectors on an optical disk 16, N parity checks are calculated for each of N sectors different in both track number and sector number by a parity calculation processing part 13, and are recorded together with an information signal added with error correcting codes by an error correction processing part 12 onto the optical disk 16 by an optical head 15. At the reproducing time, when the information signal cannot be reproduced by using the error correcting codes from recorded data read out by an optical head 15, the parity is used in this case to reproduce the information signal.

Title: High-speed multi-phase reclosing wire line provided with lighting insulator device
Inventor: HAYASHI TOMOHIRO
IPC: H01B17/42
Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To reduce the number of accidents associated with lightning by providing an lightning insulator device only on the middle phase in a power transmission line of two circuits and three phases supported with an electric power line in upper, middle and under arms of a pylon provided with two overhead earth-wires on the top part. SOLUTION: Two overhead earth-wires 4 are disposed on the top part and an lightning insulator device 3 is disposed only on the middle phase. The lightning insulator device 3 carries current when receiving a high voltage due to thunder surge and flows the current through a pylon 1 or an electric power line. When summertime thunder and wintertime thunder hit the top part, most of the thunder surge current is split to the overhead earth-wires 4 and the rest is split to respective upper, middle and under arms through the pylon. The probability of the summertime thunder hitting the middle phase electric wire extending in the side more than the upper phase does is high next to the overhead earth-wires 4.  Disposing the lightning insulator device 3 only on the middle phase having the maximum probability of accidents due to the thunder surge minimizes the number of the lightning insulator device 3 to be disposed and sufficiently prevents ground accidents.

Title: Liquid crystal display element
IPC: G02F1/13
Filed: 1992-02-19
Abstract: PURPOSE:To obviate the failure in cutting out the liquid crystal display element to a final outside shape and the generation of image recognition errors by providing a cutting reference marker to be used at the time of cutting out the liquid crystal display element to the final outside shape in a liquid crystal injection port part where a sealing pattern is lacked. CONSTITUTION:One of the cutting reference markers 9 to be used at the time of cutting out the liquid crystal display element 1 sealed by a UV curing resin after injection of a liquid crystal to the final outside shape is formed in the position of the liquid crystal injection port 8 where the sealing pattern 7 is lacked. The other marker 9 is provided in a region to be cut off by cutting. On the other hand, a black light shielding part 6 for shutting off the light leaking from a back light is formed to the extreme margin of the sealing pattern 7. The cutting reference marker 9 is, therefore, not concealed even if the black light shielding part 6 is widened and consequently, the problem of the failure in cutting is eliminated. Since the cutting reference marker 9 is provided under the seal so as not to overlap on the black light shielding part 6, the image recognition errors are entirely eliminated.

Title: Frequency modulator
Inventor: MACHIDA KAZUMI
IPC: H03D9/04
Filed: 1983-02-25
Abstract: PURPOSE:To eliminate hysteresis, to eliminate the need for a matching circuit, to attain miniaturization and no adjustment and to make the modulator highly stable by terminating a transmission line connected to a base terminal with a resistive terminator, coupling the line to a resonator at a prescribed position and coupling a modulation circuit provided with a varactor diode to this resonator. CONSTITUTION:Since the line is terminated by the resistive terminator 11 when the resonator 8 is not coupled with the transmission line 5 of the base side, the oscillating condition is not satisfied. Then, in coupling the resonator resonated at a required frequency at a position apart by nearly lambdag/4 (where; lambdag is a line wavelength at a resonance frequency) from the base side, the absolute value of a reflecting coefficient viewing the resistive terminator side from the base terminal 2 is nearly the unity at the resonance frequency, the oscillating condition is satisfied and the oscillation is started. Since this resonance frequency is changed by a reactance change caused by a junction capacitance of the varactor diode 10, when a modulation signal is impressed to the varactor diode 10, the oscillating frequency is changed and the frequency modulation is attained. When the resonator 8 coupled with a modulation circuit 9 is parted, the oscillation stop is caused, no hysteresis exists, and no spurious wave is irradiated externally.
