Abstract: PURPOSE: To surely avoid agglutination of a piston preventing an injection quantity control function by expanding a play between a head part of a pump piston and a cylinder wall in a dangerous range. CONSTITUTION: A play is provided between peripheral surfaces of head parts 17, 37 of a pump piston 1 and a wall of a cylinder hole 3.

Filed: 1982-04-28
Abstract: PURPOSE:To make possible ignition phase control in proportion to the change of the rotational frequency of a wheel by a method wherein ignition time in a strobing apparatus is obtained by numerical calculation. CONSTITUTION:Vibration generated by the rotation of a tire to be measured is detected and converted into an electrical signal by a pickup 3, the signal being applied to an integrating circuit 5. The output signal of the integrating circuit 5 is compared with a reference signal through a comparator 20 and produced in the form of a square wave. The square wave output from the comparator 20 is inputted to a frequency measuring circuit 30. Subsequently, A phase- shifting value relying on the rotational frequency of a wheel is calculated by an arithmetic circuit 60 from the measured result in the frequency measuring circuit 30. An ignition pulse is generated through a pulse generator 70 by means of the output signal from the arithmetic circuit 60. Ignition phase control can thus be carried out in proportion to the change of the rotational frequency of the wheel.

Title: Branching and inserting circuit of data transmission line
Inventor: INAO KIYOHARU
IPC: H04L5/06
Filed: 1983-04-20
Abstract: PURPOSE:To use a small-sized and economical data transmission line with a simple constitution for multi-frequency system by using a transformer to be coupled with the data transmission line in common with a filter. CONSTITUTION:The 1st channel CH1 having a high frequency band and the 2nd channel CH2 having a low frequency band are multiplied in frequency and transmitted to the data transmission line D. The secondary side winding of a transformer T1 is connected to the CH1 and the secondary winding of a transformer T2 is connected to the CH2. Respective primary windings of the transformers T1, T2 are connected in series and the circuits connected in series are connected to the transmission line D in parallel. A capacitor C is connected to the primary winding of the transformer T2 in parallel. The number of turns of winding of the T1 is set up to a small value and the number of turns of winding of the T2 is set up to a large value. Since the impedance of the capacitor C is low at the high frequency band of the CH1 and the impedance of the T1 is low at the low frequency band, said status is made equivalent to the status connecting the primary winding of the T2 to the transmission line D in parallel. Since amplifiers for respective frequency bands can be connected to the CH1, CH2, it is unnecessary to insert an amplifier for a wide band to the transmission line D.
