Title: Device hermetically sealing cable introduced into acinous multi-contact connector
Inventor: ARAN JIYAN RUSHIAN MARII
IPC: H01R13/187
Filed: 1990-11-05
Abstract: PURPOSE: To provide a device for arranging cables provided with different diameters in the same connector element by providing a cylindrical coupler in the passage of a tightly sealing blanket. CONSTITUTION: For the connector element, the tightly sealing blanket 3 is arranged on one side of an insulation element 1. An electric cable 6 crosses the tightly sealing blanket 3 and is held inside the passage whose entire body is indicated by 7, aligned with a hole 2. The passage is provided with a center conductor 8 provided with the diameter smaller than the outer diameter of the smallest cable to be inserted and plural concentric recessed parts 9 in a truncated conical shape as the whole and the maximum diameter of the concentric recessed part 9 is turned to be slightly larger than the maximum diameter of the largest cable to be inserted. By the recessed part 9 provided with the maximum diameter, during the introduction of the cable 5 provided with the diameter larger than the diameter of the conductor 8, the center conductor 8 is expanded in a radial direction.  Thus, when the cable is introduced to the passage 7, the cable is held in a tightly sealed state in the passage by the elasticity of the tightly sealing blanket 3.

Title: Arc extension circuit
Inventor: IWAI HIROMI
IPC: G01R31/333
Filed: 1987-11-28
Abstract: PURPOSE:To extend wavelength of a discharge current while obtaining a specified discharge current peak value, by connecting a series circuit of a discharge gap and a linear resistance in parallel to a non-linear characteristic resistance. CONSTITUTION:When a discharge gap G1 is operated to discharge a capacitor C1, a discharge current is initially made to overlap a current of a current source passing in series through an impedance Zi and a non-linear resistance NLR. When the current i1 arrives near a specified discharge current peak I1p, a terminal voltage of the non-linear resistance NLR reaches a voltage V10 enough to cause a discharge of a discharge gap G3 and a discharge current i2 begins to flow through the discharge gap G3. As a resistance of the non-linear resistance NLR increases sharply with the lowering of a terminal voltage of the capacitor C1 due to the discharge, the current i1 reduces quickly down to zero in substance at time t2. This enables the obtaining of a discharge current waveform with a large wavelength having a specified peak as a whole.

Title: Semiconductor device
Inventor: IWADE SHUHEI
IPC: H01L21/52
Filed: 1986-12-19
Abstract: PURPOSE:To obtain a semiconductor device in which a chip and a substrate are not separated by bonding the chip to the center of the substrate with a hard first adhesive, and bonding it to the periphery with a soft second adhesive. CONSTITUTION:An adhesive 4 has a strong bonding strength, an adhesive 5 has a weak bonding strength, the adhesive 4 is hard, and the adhesive 5 is soft. When a temperature cycle is applied to a semiconductor device, a lateral stress due to the difference of the thermal expansion coefficients of the chip 1 and the substrate 2 is generated, and the size is large at the periphery and small at the center. Since the large stress generated at the periphery is absorbed by the adhesive 5, the separation at the periphery can be reduced. Since the stress is small at the center, the separation of the adhesive 4 is small. Since the adhesive 4 tightly secures the chip 1 to the substrate 2, the semiconductor device is not displaced by an external force or a vibration. Further, since the periphery of the adhesive 4 is surrounded by the adhesive 5, it is scarcely affected by the influence of external moisture, and the adhesive 4 is scarcely affected by the chemical change, such as hydrolysis for affecting the influence to the separation.

Filed: 1989-11-20
Abstract: PURPOSE:To extract an additional signal inserted in a blanking period in an excellent way by selecting a period when an AGC voltage is held for a range including a vertical blanking period and a slight horizontal period before and after the blanking period. CONSTITUTION:A counter 15 generates a pulse signal terminated at the 24th-25th horizontal synchronizing signal after a vertical synchronizing signal and started at 260th-261st horizontal synchronizing signal, for example. The signal is fed to a sample-and-hold circuit 16 for AGC signal, where the AGC signal fed from an output terminal 2E to an input terminal 2F is sampled and held. Thus, keyed processing of AGC operation in a VIF circuit 2 in the case of eliminating ghost is implemented. Thus, the period when the AGC voltage is held is ranged to include the vertical blanking period and the slight horizontal period before and after the vertical blanking period. Then the signal for the vertical blanking period is made stable and the additional signal inserted for the blanking period is extracted in an excellent way.

Abstract: PURPOSE:To eliminate manual operation and to obtain a highly accurate clock by receiving a radiation wave by selecting a specific broadcasting station, extracting a time signal, resetting a timer circuit at the time of the inputting of a time signal, and thus executing the time correction. CONSTITUTION:A power supply on/off control circuit 9 monitors a time from the timer circuit 8 and at a time a few tens of seconds before, for instance, seven o'clock, turns on a power supply switch SW 1. Accordingly, a tuner 1 starts receiving, for instance, the broadcasting radio waves of NHK, and receives a time signal at seven o'clock. Two pieces of 400Hz signal passes through a BPF 3, frequency-voltage converted, and respectively let a timer circuit 6 count up by one, and the output of it 6 come in an H-level. Thereafter, an 800Hz signal passes a BPF 2, frequency-voltage converted, and a pulse voltage 70 undergoes an AND circuit 7, and reaches the reset terminal of the circuit 8. Consequently, the circuit 8 is reset simultaneously with the time signal, and at this very moment, the circuit 8 is corrected at seven o'clock to the unit of second. Thereafter, the circuit 9 turns the switch SW 1 off. This time correction operation is executed under the interruption of power.

Filed: 1996-10-28
Abstract: PROBLEM TO BE SOLVED: To prevent the state of a reception modem from being transited into a demodulation state of control channel data in mistake by conducting sequence control based on non-detection/detection of a partial page control restoration frame in the ECM mode during reception of primary channel data. SOLUTION: A state 100 indicates a primary channel data(PCD) demodulation state of a reception modem and a state 101 depicts a control channel data demodulation state of the reception modem. The reception modem stays in the state 100 while not detecting (1-1) a partial page restoration control frame(RCP) during the reception of the PCD. The PCD in the ECM mode are made up of a synchronizing signal, facsimile coded data(FCD) and the RCP frame, and when any RCP frame is detected, it is regarded as the end of the FCD, the reception modem is transited to the state 101 through the detection (1-2) of the RCP. Thus, even on the occurrence of a line fault such as momentary interruption, the state transition from the state 100 into the state 101 is conducted without an error.
