Title: Device for inspecting position of sealing material in pipe joint
Inventor: MAKI ATSUSHI
IPC: F16L21/02
Filed: 1993-06-03
Abstract: PURPOSE:To inspect the position of sealing material in a pipe joint by remote control by hanging down an inspection device to fit it into an insertion port therefor and inserting a gauge into a space between a reception port and the insertion port in order to bring it into contact with the sealing material for detecting an insertion amount of the gauge. CONSTITUTION:After an inspection device 6 is hung down from above the joint parts of pipes 1 and 2, a fixing member 7 therefor is attached to an insertion port 4 and a moving member 14 is arranged along the outer circumference of the port 4. By operating a motor 19 to send a first operating axis 18 to the reception port 3 side, the member 14 is moved to the reception port 3 side and, at the same time, a gauge protection member 30 is brought into contact with the end face of the port 3. The member 14 further approaches the reception port 3 side and the tip ends of a plurality of gauges 21 arranged in the circumferential direction are inserted into a space between the ports 3 and 4. In a case where a sealing material 5 is abnormally shifted to the inner side of the port 3, the tip end of a gauge 21 is shifted to the inner part, so a moving block 24 cannot be detected by a detection sensor 29 and the positional abnormality of the sealing material is found out. The gauge 21 is protected from the outer foreign matters.

Abstract: PURPOSE: To eliminate the adverse influence of the hysteresis of light emission luminance on impressed voltage by removing the charges remaining at the boundaries between an EL light emitting layer and electrical insulating layers. CONSTITUTION: The impressed voltage is applied between the electrodes X and Y of the thin-film EL element 41 for display from a driving device 61. The transparent electrode X having translucency is formed by vapor deposition on the glass substrate 71 of the thin-film EL element 41 and the first electrical insulating layer 73 is formed thereon. The EL light emitting layer 74 is sealed in the space between another one second electrical insulating layer 75 and the first electrical insulating layer 73 and the electrode Y is formed on the second electrical insulating layer 75. Driving voltage pulses above the light emission initiation voltage are impressed between the electrodes X and Y for the light emission of the EL light emitting layer 74.  Voltage pulses for negating the residual charges which are of the polarity reverse from the polarity of this driving voltage and are nearly the light emission initiation voltage are thereafter impressed thereon, by which the charges accumulated and remaining at the boundaries between the EL light emitting layer 74 and the electrical insulating layers 73, 75 are negated.

Abstract: PURPOSE:To reduce power consumption and hence improve preheating efficiency and shorten processing time by disposing a heat reflecting plate over the entire surface of a wafer located at a gap where the wafer and a target are opposed upon the preheating of the wafer, and removing the same upon sputtering. CONSTITUTION:A heat reflecting plate 20 comprises a metal plate (e.g. 3mm thickness) finished in its surface to a mirror surface, which plate is disposed at a position separated 2-3mm from the front surface of a wafer 1, configured in its external surface to the same size as that of the wafer 1. Further, the heat reflecting plate 20 is set such that it can be removed from a gap where the wafer 1 and a target 3 are opposed, by rotation of a moving lever 21. Additionally, the heat reflecting late 20 is disposed at the front of the wafer 1 facing the same upon preheating to prevent heat from being dissipated from the surface of the wafer 1, and the heat reflecting plate 20 is eliminated from the surface of the wafer 1 upon sputtering. Hereby, effective preheating can be achieved together with the reduction of power consumption and the reduction of processing time.

Abstract: PURPOSE: To ensure that an increase in cooling effect owing to an increased oil pass amount and the return of unnecessary gas to a low-pressure chamber lead to reduction of load, by forming a housing and a cylinder ring of differnet materials and utilizing the difference in coefficient of linear expansion for enlarging gaps.  
     CONSTITUTION: By forming a cylinder ring 2 of a material which has a coefficient of linear expansion smaller by 2W8×10 -6 /°C than that of the material for a housing 1, such arrangement is made that the gaps between the ring 2 and frame plates 4 and 5 stopping up the ends of the housing 1 are enlarged with the rising temperature of the compressor. By this arrangement, the bypass circuit extending from the high- pressure side 14 of a cylinder chamber to a low-pressure chamber 13 through the gaps and a bypass line 19 of the housing 1 is enlarged. As a result, driving power can be reduced largely, while procuring the required amount of a refrigerant gas, by a reduction in frictional heating owing to enlarged gaps, by a reduction in frictiona heating owing to enlarged gaps, an increase in cooling efficiency, and the return of unnecessary gas to the chamber 13.

Title: Ring signal transmitting circuit
Inventor: TERASAKI YUTAKA
IPC: H04M3/06
Filed: 1993-06-03
Abstract: PURPOSE:To increase the number of subscriber lines which can be stored by providing the timing control circuit group which controls the operation timings of ring relay contacts and using a ring signal generator having a certain current driven capability. CONSTITUTION:In the case of the ring signal which is turned on for one second and is turned off for two seconds, the circuit is so constituted that three ring relay contact control lines are inputted to one timing control circuit 5. Even if ring turning-on requests of three lines (n), n+1, and n+2 are simultaneously inputted to the timing control circuit in this state, opportunity for ring turning- on/off is given to each line once for three seconds, and the timing of this opportunity is different among respective lines by one second. Consequently, the ring signal is actually outputted to lines (n), n+1, and n+2 in order even when the ring turning-on/off request is simultaneously inputted to these three lines (n), n+1, and n+2 from PCM-IN. Thus, simultaneous output of ring transmission of three lines does not occur.

Abstract: PURPOSE: To enable measurement of low frequency of a commerical power source with high precision by a method wherein the device is formed by providing a flip- flop circuit which is set by the output of a one-shot circuit and reset by the output of a counter circuit.  
     CONSTITUTION: The input frequency is transduced into a rectangular wave by a waveform shaping circuit 1 and generates a pulse at a rise time of input in the one-shot 2, and the pulse is inputted in the set terminal of the flip-flop 3. On the other hand, the pulse of an oscillating circuit 4 giving a frequency higher enough than the input frequency is counted by a binary counter 5 and the output pulse thereof is inputted in the reset terminal of the flip-flop 3, while the counter 5 is reset by one output of the flip-flop 3 and the DC output in proportion to the input frequency is taken out from the other. Since the component which incurs the change in the time-constant with the passage of time, such as a capacitor and a resistance, is not used, the low frequency can be measured with high precision.
