Title: Pressure control valve
Inventor: YAMADA TOSHIO
IPC: F16K31/02
Filed: 1987-08-05
Abstract: PURPOSE:To aim at enhancing the durability and operational reliability of a pressure control valve by transmitting the sound pressure of a sound wave generated by a piezo-electric element so as to vibrate a diaphragm. CONSTITUTION:A piezo-electric element 28 vibrates in accordance with input and feed-back signals to a controller 32 so as to generate sound pressure which is amplified by a resonating chamber 26a so as to vertically vibrate a diaphragm 29 and a plunger 33. Due to vibration of a plunger 23 a nozzle 24 is opened and closed, causing the fluid pressure of a fluid chamber 21 to vary so as to move a diaphragm 17, resulting in opening and closing of a main valve 14. With this arrangement there is no mechanical coupling between the piezo-electric element and the diaphragm 29 so as to eliminate deformation of the piezo-electric element, thereby it is possible to surely prevent the piezo-electric element from being damaged.

Title: Color image display unit
Inventor: NAKANE TAKAYUKI
IPC: H01J29/76
Filed: 1997-07-23
Abstract: PROBLEM TO BE SOLVED: To correct changes of a YPB component in landing even after ITC adjustment by providing a coil for correction which is positioned at the lateral end of an electron gun of a deflection yoke, and generates both or either magnetic fields of the horizontal and vertical direction that affect an electron beam near the lateral end of the electron gun of the deflection yoke. SOLUTION: A magnetic field F2 opposite to a horizontally deflected magnetic field F1 is generated near the lateral end of an electron gun of a deflection yoke 3, that is, in the area where an air-core coil 4 for correction is positioned, and induced electromotive force which intends to counteract the magnetic field F2 opposite to the magnetic field F1 is generated in the coil 4. Further the coil 4 forms a closed circuit through a variable inductor 5, therefore an electric current is generated by the induced electromotive force, and a magnetic field F3 having same direction as the horizontally deflected magnetic field F1 is generated in the coil 4 part. The coil 4 generates the magnetic field F3 by the induced magnetic field from the deflection yoke 3, therefor does not require current by an external power source.

Further the surface part, ground by the primary honing work, and the other bore surface are smoothed by secondary honing work. In this way, a hard composition part to be ground by the secondary honing work can be decreased to a small amount by previously grinding the part through the primary honing work.

IPC: G01S17/10
Filed: 1982-11-12
Abstract: PURPOSE:To enable the attainment of high accuracy in the measurement of a long distance by calculating the distance to a target on the basis of a distance corresponding to the time difference between a reflected pulse laser beam and a pulse laser beam taken out after the round-trip reflection in a cavity resonator system, and the distance of the round trip of the pulse laser beam within a cavity resonator. CONSTITUTION:The pulse of an image shown as a signal image 131 is assumed to be an n-th output pulse from a plane reflector 104-1, and the pulse of an image shown as a signal image 132 to be a reflected pulse from a target reflector 133. When the time difference, i.e. the distance difference between said two pulses is delta, the distance rho to the target can be expressed by the following equation on condition that the inherent delay within a system is excepted: rho+nL+ delta/2. A cavity resonance round trip interval L can be made constant so that it is limited within an error of about 10<-8>, i.e. an error of 0.5mm. to 50km in practical use. The resolving power of a streak tube 125 is about 10ps (3mm. in length) in some of conventional products.

Title: Detecting method for phase of induction generator
Inventor: HATA HARUYOSHI
IPC: H02H7/06
Filed: 1981-12-08
Abstract: PURPOSE:To detect the phase of an induction generator without temporary connection thereof which causes disturbance to a system, by connecting and driving the induction generator and a synchronous generator, and knowing the phase order of the synchronous generator. CONSTITUTION:An induction generator 1 is driven as an induction motor in a manufacturing factory. To this induction generator 1 a synchronous generator 2 is connected mechanically, and the phase order is recorded by a phase detector 5. In a site where the induction generator is to be installed, the synchronous generator 2, together with the induction generator 1, is transported from the manufacturing factory and installed for phase detection. Then, a phase detector 9 is connected thereto, and the induction generator 1 and the synchronous generator 2 are made to rotate normally by a driver 7. After the phase order is investigated, the phase order of feed wires U2, V2 and W2 is investigated through the intermediary of PT10, and correct connections are made. Thus, it is only required to transport simultaneously a synchronous generator of a small capacity, and not required to drive the induction generator as a motor by temporary connection thereof. Therefore, no effect is brought about on a system.

IPC: H04R9/00
Filed: 1984-09-20
Abstract: PURPOSE:To reduce the reakage flux around a speaker by arranging a sub- magnet magnetized reversely to a main magnet on the lower side of a magnetic field part including the mainmagnet and contacting the outer peripheral part of an upper plate with the inside of a frame. CONSTITUTION:The sub-magnet 11 magnetized vertically to the main magnet 8 is arranged on the bottom of the frame 12 formed by working a ferromagnetic substance and the outer peripheral part of the upper plate 10 is contacted with the inside of the frame 12. Consequently, the magnetomotive force of the sub- magnet 11 is added to that of the main magnet 8 in a gap between a center pole 7 with which a voice coil 1 is engaged and the upper plate 10, so that the magnetic flux density of the gap is improved. Since the whole frame 12 is magnetized with the S pole, the frame 12 is crossed by all magnetic flux radiated from a part magnetized to N pole which is arranged on the inside of the frame 12 and leakage flux around the speaker is reduced.

Abstract: PROBLEM TO BE SOLVED: To analyze and determine the quantity of sesquiterpenes in a hop originated volatile aromatic component easily and correctly without being influenced by other volatile components usign a gas chromatography-mass spectrometry (GCS-MS) and a selective ion detecting method. SOLUTION: Sesquiterpenes in a hop originated volatile aromatic component existing in a drink with hop used as a part of material is detected using a GCS-MS and a selective ion detecting method.

Oxygen contained sesquiterpene with one or more oxygen atoms combined with the sesquiterpene, to be concrete, humulenol, humuladienone, and the like, can also be named. The sesquiterpenes can be correctly determined since volatilization caused by heating during operation is not much generated because of its relatively high boiling point.

Abstract: PURPOSE:To enable the detection of the end of a printing medium irrespective of the position of binding holes of a printing medium such as slips by providing time monitoring means at the output side of a sensor and discriminating the vertical holes and the rear edge of the slip. CONSTITUTION:A sensor S detects one end of binding holes H at the time t1, thereby varying the level of a detecting signal B from ''0'' to ''1'', and the sensor S detects the other end of the hole H at the time t2 elapsed for the moving time t, and the level of the detection signal B is returned to ''0''. A flip-flop 5 is set by the rise signal of the detection signal B obtained at the time t1, and a timer 3 is started. The timer 3 produces an output signal C at the time t3 after the elapse of the time T, where t<<T. When the rear edge of the slip is detected, no fall signal is produced at the detection signal B. Accordingly, the flip-flop 5 is not reset, and a flip-flop 7 is set by the output signal C, and a paper end signal G is fed to an exhaust mechanism.
