Title: Transmitting circuit of phase pulse signal
Inventor: ARAI YUKIO
IPC: H04B3/54
Filed: 1982-03-26
Abstract: PURPOSE:To obtain a circuit having a good transmitting efficiency, by deciding timing of on/off of the 1st and the 2nd electronic switches so as to switch off the 2nd electronic switch while the 1st electronic switch is turned on and generating plural phase pulses in a short interval. CONSTITUTION:Since an electronic switch 22 provided between a charging circuit 17 and an injection circuit 21 is turned off while an electronic switch 20 is turned on, the charging voltage of a capacitor 16 is not reduced. Thus, after the electronic switch 20 is turned off, when the electronic switch 22 is turned on, a capacitor 18 is charged from the capacitor 16 rapidly and the time prepared for the next transmission is reduced. Since the capacitor 16 is not discharged during the transmission with the electronic switch 22 turned off, the charging voltage of the capacitor 16 is kept constant at all times, and even if a phase pulse 27 is generated in a short interval, the capacitor 18 is charged in the same level at all times, that is, the level of the pulse 27 is the same level at the times.

Abstract: PURPOSE:To eliminate the need for a booster pump in a valve closing circuit by connecting a secondary side of a charge relief valve in a pump-controlled closed circuit to a secondary side of a low pressure relief valve and connecting the relief valve to a pipe way at the suction side of a driving pump in a valve- controlled closed circuit. CONSTITUTION:If a load is high in a pump-controlled closed circuit, an oil comes out of a low pressure relief valve 8, passes through pipes 18, 19, 20, opens a relief valve 21 which is disposed in a pipe way at the suction side of a driving pump 10 in a valve-controlled closed circuit and cools a hydraulic pump 1. If the load is extremely low, an oil discharged from a charge relief valve 3 passes through pipe 17, 18, 19, opens the relief valve and cools the pump 1. In the valve-controlled closed circuit, the oil discharged from the pump-controlled closed circuit is constantly fed in the suction-side pipe 20 and the relief valve 21 keeps a suction pressure of the pump over a certain level, thereby producing no cavitation.

Title: Automatic focusing method
Inventor: SUZUKI HIROMASA
IPC: G03B13/36
Filed: 1988-03-02
Abstract: PURPOSE:To improve accuracy in focusing by returning a line sensor by about half of specified distance and performing automatic focusing after confirming that a state where an image exists at the time of reading the image in placing the line sensor in a focusing zone is kept while the line sensor is moved by the specified distance. CONSTITUTION:A CPU 40 obtains a slice level (c) from a histogram. The slice level (c) is determined in density near alpha where the frequency (x) of the histogram approaches the lowest. The CPU 40 outputs the slice level (c) to a comparator 58 and the number of times of white-and-black inversion at the time of slicing an image signal (a) with said level (c) is integrated in a counter 60. When the counted value (n) is larger than a set value N, it is judged that the image exists and the line sensor 34 is moved by a distance l. At such a time, if the state n>N continues during the movement by a distance L or more, the line sensor 34 is returned by L/2, where automatic focusing is performed. Thus, it is difficult that malfunction is caused by scratch and dust and the accuracy in focusing can be improved.
