Patent JP-S57123723-A (JP)
Title: Oscillator
Inventor: SHIOTANI YUUICHI
IPC: H03K4/50
Filed: 1981-12-14
Abstract: PURPOSE:To vary the oscillation period of an oscillator, which oscillates by charging and discharging a capacitor repeatedly, linearly when a control voltage is adjusted, by composing a charging circuit of a constant current circuit. CONSTITUTION:A charging circuit 3 for a capacitor (C)2 connected to a differential amplifier 1 uses a constant current circuit composed of a transistor (TR) 3b, a diode 3c, and resistances 3d-3f, and the charging voltage of the C2 is raised linearly. When the charging voltage of the C2 rises above a control voltage from a terminal 6 to the base of the TR1b of th amplifier 1, a TR1a turns on and a TR1b turns off, which is detected by the TR7 of a switching circuit 7 to turn on the TR4b of a discharging circuit 4, thereby discharging the C2. Simultaneously, the TR5c of a bias power source circuit 5 is turned on to apply a low-level bias voltage to the TR1b. When the voltage of the C2 drops below the bias voltage of the TR1b, the TR1a turns off and the TR1b turns on, performing oscillation. In this case, the oscillation period varies linearly with the control voltage from the terminal 6.

Title: Pulse compression transmitter/receiver
Inventor: KAWAMURA HIROTSUGU
IPC: G01S13/28
Filed: 1985-09-12
Abstract: PURPOSE:To achieve a higher distance resolution, by generating a chirp signal on the basis of a waveform memorized in a memory element. CONSTITUTION:A waveform memorized in a memory element 12 is read out with a read control circuit 11 and a chirp signal with frequency varying monotonously is generated from a signal generating section 10 to be transmitted. This signal is received and compressed at a pulse compressing section 18 having a pulse compressing chirp filter 18. With such an arrangement using a pulse- stretching chirp filter, not a chirp signal generator, the pulse-stretching chirp filter and the pulse compressing chirp filter on the receiving side are made free completely from restraints such as conjugation of delay time characteristic thereby improving the distance resolution.

Filed: 1990-08-01
Abstract: PURPOSE:To fetch a future instruction from a cache system and to perform fast processing without making access a main storage area by providing a designation means of information format, and a selection means for cache memory which performs information transfer. CONSTITUTION:As access to the main storage area 118 by a processor 101, two kinds of the fetch of an instruction to be executed and data access such as the write and readout of data are prepared.

The comparator 120 compares it with the address tag from the processor 101, and when coincidence is obtained, a cache hit state is set. When the instruction fetch of the address is performed, it goes to cache hit, and the data is fetched from the cache memory.
