Filed: 1982-02-05
Abstract: PURPOSE:To give an optical check to the press-contact state of a terminal, by giving an optical scan of axial direction to the press-contact part of a terminal press-contact electric wire and comparing the output information given from the scanning means with the information set previously. CONSTITUTION:Light is irradiated to the terminal press-contact part of a terminal press-contact electric wire 2 to be checked from a light source 3 via an optical fiber 5, and this reflected light is scanned by a photodetecting part 7a where many photodetecting elements are arrayed on the lower face of an image sensor 7 and in the axial direction of the wire 2. The output information given from the sensor 7 is led to a controller C containing a central controller CPU and a memory MEM. Then the number of data of same value are successively counted out of the binary-coded signal data detected by the controller C every time the value of data varies. These counted values are compared successively with the prescribed fixed value. From the result of this comparison, the quality is checked for the press-contact state of the terminal of the wire 2.

Title: Relay start circuit in signal conversion circuit
Inventor: TERASAKI YUTAKA
IPC: H04Q1/30
Filed: 1990-01-29
Abstract: PURPOSE:To prevent a defective operation without increasing power consumption in the operating state of a relay in an exchange by releasing a current limit function of a constant resistance circuit at the start of the relay of the exchange. CONSTITUTION:When a switch S1 is closed attended with the leading of a level at an input terminal I1 from a low level to a high level, a transistor(TR) Q1 is conductive. In this case, when a sensing current of a relay 3 is larger than a limit current of a constant resistance circuit, the relay 3 is not started. The level of an input terminal I2 rises from a low to a high level for a short period at this start and a break contact rI is opened attended with the operation of a relay RL to release a current limit function and a current required for the start of an exchange relay 3 flows as a 2-wire loop current and the relay 3 is surely started. The signal the input terminal I2 is restored to a low level after a prescribed time, then the current limit function is restored but when the level is a value of an open current or over, the operation is maintained. Thus, the power consumption during holding is saved.

Title: Power unit for audio amplifier
Inventor: KITA TOSHIYUKI
IPC: H04N5/60
Filed: 1987-01-29
Abstract: PURPOSE:To prevent the occurrence of unpleasant sounds at the time of a application of power by providing a time constant circuit in a constant-voltage control circuit and making an output voltage slowly rise for a specified time. CONSTITUTION:When a voltage is supplied to the constant-voltage control circuit 40 from the power source, since the terminal voltage of a capacitor 47 is zero at first a transistor 45 goes to a conductive state and the supply of the reference voltage of a Zener diode 42 is interrupted, so that the base voltage of the transistor 41 goes to approximately zero. The resistors 44 and 46 are set so that their resistance values are R44<=R46 and the capacitor 47 is charged with the base current of the transistor 45 which passes through a resistor 44. Since the time constants C47 and R46 caused by the resistor 46 and the capacitor 47 are large, the base voltage of the transistor 45 in the conductive state slowly rises and the base voltage of the transistor 41 and also the emitter output voltage of the transistor 41 slowly rises with the base voltage of the transistor 45. Thus, the unpleasant sounds occurring at the time of the application of the power can be prevented.

Filed: 1989-01-27
Abstract: PURPOSE:To heighten the ionization efficiency with simple constitution for obtaining a relatively big current by arranging an anode having potential different from a second plasma generation chamber between a first plasma generation chamber and the second plasma generation chamber. CONSTITUTION:Besides providing a first plasma generation chamber 6 with an anode 4, a second plasma generation chamber 8 is provided with an anode 7, both of these are connected to an acceleration power supply 16.

Abstract: PROBLEM TO BE SOLVED: To realize a large-area and high-precision liquid crystal device by forming a chiral smectic liquid crystal having a specified or larger ratio of the apparent tilt angle to the real tilt angle in such a manner that the chiral smectic phase in a driven state has a layer structure of plural kinds and that the anisotropy of the dielectric const. of the liquid crystal is controlled to a specified value or lower. SOLUTION: In this liquid crystal element, a chiral smectic liquid crystal having at least two stable states is used, and the liquid crystal has >=0.5 ratio of θa /Θ, wherein θa is the apparent tilt angle and Θ is the real tilt angle. The chiral smectic phase which is driven has a layer structure of plural kinds. The anisotropy Δε of the dielectric const. of the liquid crystal is controlled to <=-1. The state with >=0.5 θa /Θmeans that the liquid crystal is in a uniform state while the twisted state of liquid crystal molecules is suppressed between substrate and that extremely good contrast is obtd.  By controlling the anisotropy Δεof the dielectric const. of the liquid crystal to <=-1, fluctuation near the interfaces in the layer structure can be suppressed when the liquid crystal is driven, and the contrast of the liquid crystal element can be improved.
