IPC: H04J3/14
Filed: 1988-09-30
Abstract: PURPOSE:To discriminate a faulty location momentarily by adopting the constitution such that a fault diagnosis of a relevant channel of a time division multiplex means is applied automatically when an output time of a transmission request signal outputted from a terminal equipment elapses a preset time. CONSTITUTION:Upon the receipt of an output signal of a time measuring section 108 receiving one of input signals, a control section 124 outputs a control signal 200 to changeover devices 104, 116 and a time division multiplexer 106 when it is discriminated that an output time of a transmission request signal in the channel elapses a setting time. As a result, the changeover device 104 is thrown to the position of a test signal generating section 102 and the changeover device 116 is thrown to the position of a test signal collation section 120, a digital loop is formed to a channel of the time division multiplexer 106, a test signal outputted from the test signal generating section 102 is inputted to the test signal collation section 120 via the digital loop and the test signal is collated. Thus, a control section 122 receives the output signal of the collation section 120 to output a control signal 201 to the changeover devices 104, 116 and 114 and the time division multiplexer 106.

Abstract: PURPOSE:To enable to form an amorphous silicon by inserting a substrate into a vacuum vessel, then heating, sufficiently degassing, then feeding the prescribed quantity of stock gas, separating the vessel, a gas feeding system and an exhausting system, and generating a glow discharge. CONSTITUTION:A substrate 3 is mounted on electrodes 4, heated by a heater 2 while evacuating in vacuum, and degassed. Then, a vessel 1 and an exhausting system are separated by a connecting portion 11. Then, valves 23, 24 are opened, SiH4 is, for example, fed from a bomb 7 in the suitable quantity into the vessel 1, the SiH4 is exhausted from a purging pipe 9, leaked, and a gas piping system is separated from a connecting part 8. When the gas feeding system and the exhausting system are disconnected, only the heater 2 and a discharge power source 6 are connected to the vessel 1.

Abstract: PURPOSE:To substitute a system file for another without interrupting on-line service by independently and synchronously operating respective duplexed central control devices. CONSTITUTION:At normal operation, a message inputted from the external through a line 6 and a signal distributor(SGD) 5 is processed by a CPUA 1.

Then the CPUB 2 loads the new system file from an external memory device B(MB) 4. A new processing request message after completing the message processing of the CPUA 1 is inputted from the SGD 5 to the CPUB 2, which executes processing based upon the new system file. Then the new system file loaded to the CPUB 2 is copied to the CPUA 1 and both the CPUA 1 and CPUB 2 are turned to synchronized operation status.

Abstract: PURPOSE:To reduce loss in low speed, high load state by providing a zone having a time length corresponding to the amplitude of an output current in a zero vector output zone, and generating a value vector immediately before the output zone in a zone corresponding to the output current. CONSTITUTION:An AND gate 21 interrupts a zero vector instruction output of a second comparator 16. A low level zone (value vector zone) is preserved as it is, but a high level zone (zero vector output zone) is not preserved as it is, but interrupted. The value vector immediately before is continuously output during the interrupting zone. The time length T of the interrupting zone is proportional to the amplitude of the output current of an inverter 2. In order to generate the interrupting zone in synchronization with the zero vector output zone, a phase inverted triangular voltage of the triangular voltage used in comparison of the comparator 15 is formed by an inverting amplifier 29 having a gain A, and input to a third comparator 28. On the other hand, the output current of the inverter 2 is amplified by an amplifier 27, and input as a current detection signal to the comparator 28.

Title: Oil-filled shock absorber for elevator
Inventor: TANAKA MASAKATSU
IPC: F16F9/342
Filed: 1994-10-12
Abstract: PURPOSE: To cope with a secular change in a shock absorbing member, and obtain a proper shock absorbing action at collision time by interposingly pressing the shock absorbing member between a receiving plate of a top part of a plunger and a pressure receiving plate, and adjusting a height of the shock absorbing member by an adjusting bolt. CONSTITUTION: Assuming that a landing car descends by passing through a normal stopping position of the lowest floor and collides with a receiving plate 8 of an oil-filled shock absorber 100 through a shock absorbing material 23, then, a plunger 7 is pushed down, and operating fluid 15 in a cylinder 3 blows out and flows in the plunger 7 according to a descent of the plunger 7. At that time, since it is narrowly squeezed by an oil blowout hole 10, strong braking force is applied to the descent of the plunger 7 by an orifice effect. Since the passage area of the oil blowout hole 10 gradually reduces by an action of a conical needle 4, the braking force is gradually increased.  Since the shock absorbing member 23 secularly becomes high in hardness, an adjusting bolt 21 is adjusted in the direction for looseneing its displacement quantity as a spring constant and pressing force become high, and the pressing force is set in a proper value.
