Title: Demodulator for binary amplitude deviation
Inventor: MIHARA MASATAKA
IPC: H04L27/06
Filed: 1984-07-31
Abstract: PURPOSE:To reduce position delay due to a transient phenomenon and to perform faster ASK system transmission by clipping a received binary ASK wave symmetrically about its center part, limiting the clipped wave below the maximum input level of a digital signal demodulating circuit, and detecting it and obtaining a digital signal. CONSTITUTION:A receiving amplifier 100 amplifies the ASK wave, a center clipper 101 performs the center clipping of the amplified ASK wave, and a limiter 102 limits its upper and lower amplitudes suitably for a tone decoder 103. The center clipper is an axially symmetrical circuit utilizing a push-pull circuit. Therefore, DC levels at both points A and B in a figure are +B/2. Further, transistors Q1 and Q2 form a complementary pair and symmetric about performance. A waveform within an amplitude range 2VBE+B.R3/(R2+R3) centered on the center part of the input waveform, i.e. +B/2 is clipped at the point A. Consequently, a waveform at the point, i.e. clipped wave is obtained.

Abstract: PURPOSE:To prevent overcurrent by starting a plurality of specific load machines in the order of priority, when they are started in same time band, thereby preventing the starting current from overlapping. CONSTITUTION:A monitor section 3 receives the operational signals from a plurality of specific load machines (air-conditioners) A1-A4. Upon receiving an overcurrent signal from an overcurrent detecting section 2 and an operational signal notifying that the plurality of air conditioners A1-A4 have started in same time band from the monitor section 3, an operating section 4 makes a decision that the temporarily interrupted air conditioners A1-A4 must be restarted with respective time lags according to a preset priority. This constitution allows prevention of overcurrent without requiring unnecessary interruption of the air conditioners A1-A4.

Abstract: PURPOSE:To construct a sand pile by effectively utulizing oil pressure by a method in which oil pressure is all concentrated on a vibrator during the penetrating operation, and the oil pressure is partly distributed to a sand forcibly pressing force and partly distributed to a drawing and vibrating force during the drawing operation. CONSTITUTION:The oil pressures of the first and second oil-pressure pumps are joined through a solenoid switch valves 7 and 8 and then supplied to oil- pressure motors 12 and 13 for vibrator. On the other hand, oil pressure in the third oil-pressure pump 3 is supplied through a solenoid switch valve 9 to a cylinder 14 for a sand forcibly discharging and pressing mechanism. Oil pressure of the oil-pressure pumps is divided by the pressure oil inlet side tube 6 of the solenoid switch valve 9 and led to the pressure oil inlet of the solenoid switch valve 8. All the pressure oil of these pumps can be supplied to the vibrator during the penetration period, and the oil pressure can be partly used in pressing sand and partly used in drawing force. The oil pressure source can thus be effectively utilized and the cost of the sand pile driver can be lowered.

Filed: 1988-07-01
Abstract: PURPOSE:To reproduce a freeze picture without flicker by controlling a selection circuit so that a timing generating circuit applies different selection depending on an odd number field and an even number field at the freeze mode. CONSTITUTION:Selection circuits 117, 118 at the freeze mode use control signals S4, S5 to select the position (b) in the even field respectively to correct the relation of scanning line.

Title: Display correcting device in float type liquid level gage
Inventor: IKEDA NAOTAKE
IPC: G01F23/40
Filed: 1983-09-05
Abstract: PURPOSE:To make it possible to display the true value of a liquid level, by providing a correcting mechanism of the amount of the extension of wire, and correcting the change in draft level of a float due to the change in weight of the wire. CONSTITUTION:A sliding wheel 3 is screwed to a screw shaft 9, which is rotated together with a wire drum 2 as a unitary body. A roller 14 is attached to one end of a correcting arm 12, which is pivoted to the center of the wheel 13. The other end of the arm is engaged with a roller guide 15, which is inclined in the direction of a clock by an angle theta. A correcting mechanism of the amount of the extension of the wire is constituted of said parts. When a liquid level is decreased, the weight of the wire acts on a float 18 and an error is yielded. Therefore, the wire is extended by a small amount by the correcting mechanism. The amount of correction is given by the amount of extension l1=L(piB/4+tantheta), where B is the diameter of the drum, L is the amount of movement of the arm, and theta is a guide slant angle. Therefore, even though the liquid level is decreased, the true value of the liquid level can be displayed.
