Title: Switching regulator
Inventor: HIGUCHI YOSHIO
IPC: H02M3/28
Filed: 1993-01-25
Abstract: PURPOSE:To use a common high-frequency transformer with reference to different input voltages by a method wherein the tap of a base winding is selected and used according to the magnitude of an AC input voltage. CONSTITUTION:When the title regulator is used for a 220-V AC input voltage, the base of a transistor 9 is connected to the tap 4c of a base winding 4 via a series circuit which is composed of a resistance R and a diode D. When the title regulator is used for a 100-V AC input voltage, the base of the transistor 9 is connected to the tap 4b of the base winding 4 via the series circuit which is composed of the resistance R and the diode D. Thereby, a nearly definite voltage is always supplied to the base of the transistor 9 irrespective of whether an AC input voltage is 220 V or 100 V. As a result, one transformer can be used for both 100 V and 220 V in common.

IPC: C02F11/12
Filed: 1987-02-10
Abstract: PURPOSE:To quickly and efficiently produce solid matter by heating sludge under strong agitation in an agitation tank having an impeller in the tank bottom and subjecting the sludge to continuous dehydrating, pelletizing and drying within the same tank. CONSTITUTION:A binder essentially consisting of coal ash is added at 5-50wt% ratio of the entire part to the combustible sludge which is the activated sludge generated in a biological treatment of waste water or the digester sludge of the activated sludge or pulp waste or waste liquid of fermentation or waste liquid of food processing or the residue of animal and vegetable food processing. While the sludge is strongly agitated in the agitation tank which has the impeller in the tank bottom and has or does not have a baffle plate in the tank, the sludge is subjected to indirect or direct heating or simultaneous direct and indirect heating.

Title: Friction generating mechanism
Inventor: KOKADO TOSHIYA
IPC: F16D13/64
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To make a smooth changing in torsional characteristic by a method wherein there are provided a friction disk member cooperated with a second rotary member, abutted against a first rotary member and having a recessed part; a biasing disk member having a projection part in the recess part; and an energizing member for energizing the disk member against the friction disk member. SOLUTION: A surface of a first friction washer 30 opposite to a flange 2b is formed with a recess part 31b. A friction plate 33 has a projection 33a in correspondence with the recess part 31b at a side of the first friction washer 30. Although the projecting section 33a is slid within the recess part 31b in a range of small torsional angle, as the torsional angle is increased, the projecting section 33a rides over the end part of the recess part 31b. With such an arrangement as above, the friction plate 33 is axially moved so as to make an axial compression of a wave spring 34 between it and the retaining plate 4, resulting in that a friction between the first friction washer 30 and the flange 2b is increased.  Accordingly, the characteristic is gradually changed from the first stage characteristic to the second stage characteristic and so even if a torsional vibration is transmitted, a physical shock is hardly produced.

Title: Radar holography apparatus and radar apparatus
Inventor: SHIMIZU HITOSHI
IPC: G01S13/89
Filed: 1990-02-13
Abstract: PURPOSE:To exclude the phase difference measuring error caused by phase delay even when receiving frequency is changed by comparing the receiving signals of two antennae arbitrarily selected from two or more antennae to measure phase difference. CONSTITUTION:The reflected wave from an object 1 to be detected is received by two or more receiving antennae Ra 4 and the receiving signal 13a of one RA 4 is inputted to the same position detector 5 along with the receiving signal 13b of the adjacent RA 4 to measure phase difference to output a phase difference signal. In the same way, the phase difference between the receiving signals of the second and third RAs is measured. In a phase operator 6, on the basis of the receiving signal of the specific RA, the phase difference measured value of the other receiving signals is added to calculate the phases at every RA and the calculated phases are inputted to a hologram preparing part 7. In this measuring method, since two RAs and the detector 5 are connected by respectively equal transmitting characteristics and path lengths even when phase delay is generated by the change of receiving frequency, equal phase difference is added to the signals from two RAs and set off at the time of operation. Therefore, adjustment for correction becomes unnecessary and phase difference can be accurately measured.
