Title: Flow controller and hot water supply unit
Inventor: SATO TETSUYA
IPC: F24H1/10
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To provide a flow controller in which a normal position sensor for detecting the limit position of a flow control valve can be prevented from being judged erroneously to be failed. SOLUTION: When a flow control valve is opened for a predetermined time TL1 (step 105, 106) and full-open position (limit position of normal operation range) is not detected by a position sensor, a decision is not made immediately that the position sensor has failed but the detection 15 retried. More specifically, closing operation is performed assuming that the flow control valve exceeds the full-open position and detection of the full-open position is tried by the position sensor (step 107, 108). If the full-open position can not be detected even after the closing operation is executed for a specified time TL2 a decision is made that the sensor has failed (step 111).

Title: Apparatus for measuring partial discharge
Inventor: TAMAOKI EIICHI
IPC: G01R31/02
Filed: 1982-07-16
Abstract: PURPOSE:To measure the partial discharge of electric machinery in good preciseness, by a method wherein a winding current component is detected by a high frequency current transformer to remove the minute signal component of a main circuit current component and, thereafter, the main circuit component is removed by a differential amplifier. CONSTITUTION:A high frequency current transformer 13 is an element for generating voltage proportional to a current flowing to an earth lead 7. BPF14 cuts a partial discharge signal and passes a main current component. The voltage between terminals 13a, 13b of the inlet side of BPF14 and the voltage between terminals 14a, 14b of the output side thereof are inputted to a differential amplifier 16 after said components are adjusted to a same value by an attenuator 15 and the different voltage of both voltages is divided and amplified. Because a measuring circuit is constituted as mentioned above, BPF14 may cut only the minute signal component in a main current and, by the amplifier 16, the main current component is effectively removed corresponding to the same phase signal removing ratio of the amplifier 16. Therefore, partial discharge can be measured in good preciseness.

Title: Voltage dividing transformer and power converter the same
Inventor: UCHINO HIROSHI
IPC: H02J3/38
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To suppress an electric cross current, by supplying power of the same phase to a winding wound on each leg of a three leg core. SOLUTION: The U-phase voltages e1u, e2u, e3u of a first to third inverters are compounded by a voltage dividing transformer, and a voltage eu is applied to the U-phase of a load 5. By the voltage eu, a current flows in the load 5, but this current has only a little harmonic component based on PWM control, and a current like a fundamental wave flows in the load 5. Concerning to the load current, a trisected current i1u, i2u, i3u flows in each winding of the voltage-dividing transformer, since the fundamental-wave components of the load 5 by the voltages e1u, e2u, e3u are equal.  Accordingly, voltage drops in the windings are not generated, and they do not act as inductances to the load current, since magnetomotive forces which these windings generate are equal in magnitude and their directions are reverse to each other concerning the inside of a core, and as the result the magnetomotive forces cancel each other in the windings, and any magnetic flux by the load current is generated in the core.

Title: Nc laser equipment
Inventor: SUZUKI KAZUHIRO
IPC: B23K26/064
Filed: 1988-05-24
Abstract: PURPOSE:To give a cleaning time and a replacement probability of an optical component to an operator through a display by a method wherein a means is provided to display an indication that directs cleaning of the optical component and concurrently shows a replacement probability when an oscillation hour is within a prescribed hour based on a working life of the optical element but a reduction rate of an output power is larger than a specified value. CONSTITUTION:A laser output actually outputted is monitored through a power sensor 19, whose actual output value is read in by a CPU 1, and the CPU 1 computes the reduction rate comparing the actual output power with a power direction value. If a power reduction rate exceeds a limit value but an oscillation hour of the laser is within a specified hour, the CPU 1 displays the indication on a CRT 18 that directs the cleaning of the optical component and concurrently shows a replacement probability. Here, the replacement probability denotes the ratio of a life of the optical component to an actual oscillation hour. By these processes, the degree of deterioration of an optical component does not need to be measured by an operator and moreover the replacement time can be judged by an operator depending on the value of a replacement probability, so that the optical component can be economically used without replacing it uselessly.

Abstract: PURPOSE:To restrain the generation of noise charge and restrain the flow of the noise charge to a charge transfer part to improve S/N, by providing a photodetecting part and the charge transfer part to a position having a low lattice defect density and introducing impurities to a part around them to raise the defect density. CONSTITUTION:A semiconductor substrate 1' obtained by forming a no-defect layer 11 on an internal defect layer 12 is used, and oxygen ion is charged to the no-defect layer 11 of the substrate 1' in the position around an image pickup function part consisting of a photodetecting part A, gate electrodes C and C, and charge transfer parts B and B having transfered electrodes (b) and (b). By this method, the lattice defect density of this position is raised to the same as the lattice defect density of the internal defect layer 12. Thus, the generation of the noise charge and the flowing of the noise charge to charge transfer parts B and B are suppressed considerably, and consequently, a high S/N and high- quality picture signal is obtained.

Title: Method of holding flatness of film plane in camera
Inventor: TOUKAI TAKASHI
IPC: G03B17/28
Filed: 1978-10-16
Abstract: PURPOSE: To make film plane correctly flat, prevent out-of-focus and faithfully photograph and express the subject by forming the inside of the photo detecting chamber in the camera to hermetic form and holding the film plane to the pressure plate in a close contact state by force feeding air.  
     CONSTITUTION: Film guide rollers 12a are provided on the right and left of a film plane 8, in the inner end part of a photo detecting chamber 5. As a pressure plate 6 is pressed to the guide rollers 12a by means of a supporting spring, the inside of the photo detecting chamber is held in a virtually hermetic state. When air is force fed into the photo detecting chamber 5 by rubber ball air blow device 14 the film plane 8 which was in a waving state is pressed to the pressure plate 6 in a close contact state along with an increase in the air pressure, whereby it is held flat. when the photographing ends, the air is drawn out and the film is taken up to a take-up spool 10. Since this eliminates the unstable state in the central part of the film and enables the film plane to be held flat, the subject may be faithfully photographed and expressed.
