Patent JP-H1077955-A (JP)
Title: Cylinder block
Inventor: ITO TAKASHI
IPC: F04B1/22
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To make a pressing ratio between a cylinder block and a valve plate almost constant by forming at least one groove extended to the vicinity of a cylinder port adjacent to each cylinder port continuously with at least one end part of each cylinder port. SOLUTION: A groove part 7 is extended from a kidney port 13 so as to be able to feed operating oil to a sliding contact part 5. Oil film pressure is not therefore lowered even at the overlap part of the sliding contact part 5 and a sliding contact part 15, and a constant pressure line 21 of oil film pressure is also prevented from falling in large degree from the existing side of the kidney port 13. Oil film pressure distribution is therefore almost constant during one rotation of a cylinder block even when the overlap part area of the sliding contact part 5 and sliding contact part 15 changes, so that a pressing ratio Fc/Fw determined by push-down force Fc caused by internal pressure of a cylinder and push-up force Fw caused by oil film pressure can also be controlled to be almost constant during one rotation of the cylinder block.

Title: High-frequency transmission and reception circuit for nuclear resonance picture projector
Inventor: KAWAGUCHI HIROMI
IPC: H04B1/40
Filed: 1982-12-23
Abstract: PURPOSE:To obtain a high-frequency transmission and reception circuit for a nuclear resonance picture projector having a good S/N by forming a power amplifier with a class C amplifier consisting of a pair of active elements doing a push-pull operation, and removing a harmonic noise content by a filter circuit. CONSTITUTION:An excited high-frequency pulse signal from a high frequency signal generating circuit 6 is impressed to a power amplifier circuit 8 of a class C amplifier consisting of a pair of active elements doing a push-pull operation through a distortion generating circuit 7 for compensating and erasing a signal distortion generated from the circuit 8 in the next stage. The output of the circuit 8 is processed by a BPF9, and a harmonic noise content formed during the switching time of the circuit 8 is removed. The linearity of an input/output characteristic of the circuit 8 is maintained, and the noise formed during a nontransmitting time is cut. Since the circuit 8 consists of a class C amplifier, the circuit is completely in a cutoff state, so the current is not allowed to flow and a thermal noise is not generated. Thus the high frequency transmission and reception circuit for a nuclear resonance picture projector having a good S/N is obtained.

Title: Electrostaic photographic copying machine
Inventor: NAKAO MASAHIKO
IPC: G03G15/08
Filed: 1986-09-27
Abstract: PURPOSE:To prevent toner from spilling by permitting a conduction detection circuit to detect conduction, resetting a printout counter, simultaneously disconnecting a conductive member and suppressing that an ad toner display lights up until the reading that the printout counter counts up exceeds a set value. CONSTITUTION:Where the number of printouts is less than the set value N1 with the toner remaining in a toner cartridge 17, the toner replenishment to a developing device 6 from a hopper 16 in a toner replenishment device 15 cannot catch up with toner consumption by the developing device 6 as solid black originals are continuously transferred. Even if the density of the toner temporarily drops, the ad toner display will not light up. After printouts more than the set value N1 are obtained, the ad toner display lights up due to similar causes, and the toner cartridge 17 is pulled out to be replaced. However, the toner never spills because at that time no toner remains in the toner cartridge 17. Consequently there is no such concern that a new toner cartridge just after replacement is mistakenly pulled out, and the scatter of the toner can be prevented.

Title: Body holder
Inventor: INOUE KOJI
IPC: A47C27/08
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To enable to prevent static electricity electrified by rubbing beads. SOLUTION: When this body holder is adjusted and fixed fitting to a body, air in a hollow cover 10 in which particles such as glass beads, etc., are stored is sucked by a vacuum pump 21. At that time, static electricity is generated by mutually rubbing particles, but free electrons, which are the factor of the static electricity, are neutralized by positive ions in the air via an antenna 25 set in the vicinity of an exhaust port 21 of the vacuum pump 21. Consequently the body holder is not electrified by static electricity. When glass beads with the surface plated with aluminum are used, generation of static electricity itself can be prevented.

Title: Recording/reproducing/erasing method of optical recording medium
Inventor: TANIGUCHI KINJI
IPC: G11B7/244
Filed: 1992-08-31
Abstract: PURPOSE:To positively hold data during the repeated use by casting a mixed light of a specific waveform to an azo compound at the recording time which is in the trans form at the initial state, thereby to turn the compound into the trans form-cis form of a closed ring and, casting a light of a predetermined waveform at the erasing time which changes the whole compound into the trans form in a photochromic optical recording medium. CONSTITUTION:At the initial state before recording, an azo compound contained in a recording film 3 is present wholly in the trans form. At the recording time, a light of the first wavelength, e.g. shorter than 400nm and a light of the second wavelength of 400-450nm are mixedly cast, so that the whole body in the trans form is changed into the cis form of an opening ring by the light of the first wavelength. The body is further changed into a closed ring by a part of the light of the second wavelength. Accordingly, the body is held in the trans form-cis, closed-ring form. At, the reproducing time, the light of the second wavelength is cast. Since a body of an opening ring is not present at this time, there is influence. At the erasing time, a light of, for example, 450nm or longer wavelength is cast to turn the whole body into the trans form into the initial state.
