IPC: H03L7/183
Filed: 1994-09-21
Abstract: PURPOSE:To provide a digital control type PLL device and also to provide a pulse generator and a frequency variable oscillator which are suitable to construct the PLL device. CONSTITUTION:A PLL device divides a data obtained by coding the cycle of a reference signal by a number to be multiplied to input the result of the division to an oscillation circuit 16 and produces an output signal Po by multiplying the frequency of the reference signal through the circuit 16. Then the PLL device is provided with a pulse generator 20 which generates the pulse signals in the frequency corresponding to the value (lower N bits) less than the decimal point of the result of division. When the signal is outputted, the data obtained by adding 1 to the value (higher M bits) more than the decimal point of the result of division is inputted to the circuit 16. Thus the cycle means value of the signal Po corresponds to the result of division. The generator 20 consists of a counter 26 of signals Po, a register 22 which latches lower N bits and a selector string 24 consisting of N pieces of selectors S1-S3.

Title: Pilot type pressure reducing valve
Inventor: TAKAHASHI TAKAMICHI
IPC: F15B5/00
Filed: 1987-09-11
Abstract: PURPOSE:To prevent a main valve body from generating hunching and to obtain a valve generating no oscillation by opening a control fluid inlet port on a control pressure room through a diaphragm and setting up a time constant determined by the capacity of the control pressure room and the area of the diaphragm to a value more than an hunching period. CONSTITUTION:The pressure of a feedback room 18 is varied in accordance with variation in the pressure of a secondary side room 5 and a pressure wave with a period Tf is formed. A control driving member 16 is affected by the pressure wave and allows the main valve body 8 to oscillate. Thereby, it is necessary to remove the pressure variation of the room 18. When the capacity of a control pressure room 19 is reduced, a spring constant can be increased. When the spring constant is increased, the variation of the member 16 is reduced even when feedback pressure is varied. Oscillation can be converged and stopped by setting up the capacity of the room 19 so that the time constant of the room 19 determined by its relation with the area of a diaphragm is more than the period of variation in feedback pressure, i.e. a hunching period, and the capacity can be reduced as small as possible.

Title: Magnetic recording and reproducing device of rotary head type
Inventor: TANABE TAKAHISA
IPC: G11B5/024
Filed: 1984-10-30
Abstract: PURPOSE:To make it possible to erase only one frame in any case by providing N-number of erasing heads whose track width is equal to that of recording and reproducing heads and using N-number of erasing heads in the standard mode and using only one erasing head in the N-fold speed mode. CONSTITUTION:When the standard mode is selected, both of two erasing heads 20 and 21 are used, and heads 20 and 21 trace tracks 9 and 10 formed by heads 4 and 5 to erase information because the track width of heads 20 and 21 is equal to that of recording and reproducing heads 4 and 5. When the double speed mode where the recording time is extended by twice is selected, the speed of a tape 7 is reduced to a half, and the head 5 (or 4) records information on the already formed track 9 (or 10) so that tracks overlap by 1/2 with respect to width. Since only one of heads 20 and 21 is used in this case, the head 20 or 21 traces the magnetic tape 7 once while heads 4 and 5 form tracks 9 and 10 respectively.
