Patent JP-S5534373-A (JP)
Title: Magnetic bubble memory controller
Inventor: NAGAI HAJIME
IPC: G11C11/14
Filed: 1978-09-01
Abstract: PURPOSE: To reduce the cost of a control circuit and also to miniaturize it by performing control by enabling one counter to function as much as three conventional counters do.  
     CONSTITUTION: Counter 8, counting the number of bits of a minor loop, counts up or down by one when data shift in position by one bit. On detecting the content of counter 8 agreeing with an address set to address register 7, 1st comparator 9 applies its output signal to magnetic bubble driver circuit 12 to transfer data from the minor loop to a major loop and at the same time, counter 8 is reset to zero, so that it can be used as that for major operation. The moment the major operation ends, the content of address register 7 is set to counter 8 by the output of 2nd comparator 11 and the content of counter 8 shows the address of the data.

Title: Quadrature detecting circuit
Inventor: WATANABE YOSHIHIKO
IPC: H03D3/06
Filed: 1979-08-23
Abstract: PURPOSE:To prevent degradation of the distortion rate of the FM detection output for change of the tuning frequency, by using the voltage, which is obtained by smooothing the product output of a multiplier, to control the tuning frequency of the tuning circuit of the 90 deg. phase shifter. CONSTITUTION:90 deg. Phase shifter 3 consists of coils L1 and L2 and varactor diode D1 fundamentally, and a high-level reference voltage is applied to the cathode terminal of diode D1, and a voltage equal to the reference voltage of tuning meter 5 is applied to coil L2 as the bias voltage. In the detuning state, since the control voltage of diode D1 is increased or reduced in proportion to the degree of detuning, the capacitance of diode D1 tries to reduce and increase in proportion to it and functions to cause the turning frequency of the tuning circuit to coincide with the receiving IF frequency. As a result, the distortion rate becomes good throughout all linear regions in the S curve characteristic of the control voltage.

Abstract: PURPOSE: To provide an explosionproof sealing plate which can reliably prevent an accident such as ignition by electrically connecting two sheets of metal foils having thin parts by partly connecting the foils and cutting electric current with a prescribed pressure when the inner pressure of a battery rises. CONSTITUTION: Aluminum foils 1, 7 are welded in the center parts by ultrasonic welding and in the welded parts 11, a case 4 and a metal cap 6 are electrically connected. A thin part 7a can be ruptured by pressure equal tp or lower than the pressure with which the welded parts 11 can be parted and a thin part 1a can be ruptured. When the inner pressure of a battery rises, at first the foil 7 is expanded, a crack is formed in the thin part 7a, and then the foil 1 is expanded, the thin part 7a is ruptured, the two foils 1, 7 are parted, and thus electric current can be cut. In the case the inner pressure of a battery rises further, the thin part 1a is also ruptured and a gas evolved in the inside of the battery is released outside of the battery.  Consequently, a constant current cutting pressure, which is independent of the strength of the joining parts of the metal foils, can be provided.
