Title: High-speed frequency switching oscillator
Inventor: TEZUKA MASAYUKI
IPC: H03J7/18
Filed: 1980-10-21
Abstract: PURPOSE:To enable high-speed sweep reception, by providing a plurality of oscillators which can be selected for frequency digitally. CONSTITUTION:Two digital synthesizers 8, 8' are used and desired frequency series is taken as f0, f1, f2..., then control signals 10a, 19b are added from a control signal generator 10 so that the synthesizer 8 can oscillate f1, f3, f5... and the synthesizer 8' can oscillate f0, f2, f4.... When a switch 9 picks up a section where the frequency by the both synthesizers 8, 8' is stable, a control signal 10c is applied to the switch 9 from a control signal generator 10 so that the f0, f1, f2, f3... can be picked up sequentially at the output 11. Since the switching speed of the switch 9 can be sufficiently faster than the transient response time of the synthesizers 8, 8', even if the frequency switching interval is shorter up to the same one as the transient response time of the synthesizers 8, 8', a signal negligible in the frequency  switching transient time can be obtained at the output 11.

Abstract: PURPOSE:To generate a substrate bias voltage havong a large absolute value, by supplying a pulse signal, which is generated in an output buffer circuit of an oscillating circuit, and a signal, which is generated in a bootstrap circuit, to a rectifying circuit. CONSTITUTION:A pulse signal NA, which is generated in an output buffer circuit, PP, out of signals of an oscillating circuit OSC is changed periodically between reference potential and a power source voltage VCC, and a pulse signal NB generated in a bootstrap circuit BP is changed synchronously with the signal NA. When the level of the signal NA is changed from the high level to the low level, a voltage NC of the other electrode of a capacitor C2 is changed in the negative direction by voltage components corresponding to a stored charge quantity, and an FETQ11 is turned on, and a parastic capacity CS between a circuit reference potential point and a substrate SUB is charged. As the result, a substrate bias voltage -VBE is lowered to a voltage -(VCC-Vth11) when the threshold voltage of the FETQ11 is denoted as Vth11.

IPC: G11B5/23
Filed: 1989-06-13
Abstract: PURPOSE: To easily produce a MIG(Metal-in-Gap) magnetic head without a subgap effect at a low cost by forming a CoZrNb alloy layer as a soft magnetic material on each half body of a ferrite core. CONSTITUTION: A core half body 1, 2 consists of, for example, a single crystal MnZn ferrite material.
