Abstract: PURPOSE:To ensure the accurate stabilization of levels and to simplify the constitution of a level stabilizing circuit, by inserting reference signals having the reference levels corresponding to black and white levels into a TV signal and controlling these reference signals with a common circuit so that they are set at a constant level. CONSTITUTION:The reference signals S1 and S2 are set at a reference level E1 corresponding to a black level and at a reference level E2 higher than the level E1 by DELTAE. A TV signal SV to which the signals S1 and S2 are inserted is supplied to a video output circuit 40 via an AGC circuit 20 and a control circuit 30 for DC bias. A part of the video output is supplied to a level control circuit 60 to perform the control so that the level difference between signals S1 and S2 is always constant. Furthermore a level control circuit 70 performs the control so that a beam current IK flowing to a CRT 50 when the signal E2 is inserted is set at a constant level. Therefore the level difference DELTAE is set constant by the circuit 60, and the level E2 is set constant by the circuit 70. As a result, both black and white levels are controlled at one time and can be stabilized.

Abstract: PURPOSE:To obtain a carrier detector having a fast detecting speed and being immune from noise, by obtaining a mean value of an inputted carrier signal with a non-recursive filter, and discriminating this mean value. CONSTITUTION:A mean value signal is outputted from a carrier signal at a mean value calculating circuit 13 comprising the non-recursive filter after passing through a full-wave rectifier 12.

Title: Manufacture of coil
Inventor: FUJIWARA YOSHIO
IPC: H01F41/04
Filed: 1986-07-23
Abstract: PURPOSE:To manufacture a coil as a three-dimensional part with excellent productivity and reliability, and to improve the performance of the coil by alternately winding an adhesive layer and a conductive metallic foil, cutting a coil winding body through an electric discharge machining method, molding the coil winding body to a desired shape and thermosetting adhesives. CONSTITUTION:When adhesive layers 2 and conductive metallic foils 1 are wound alternately and a coil winding body 5 is cut through an electric discharge machining method, insulation among the conductive metallic foils 1 is kept because the adhesive layers 2 are brought to the state in which the adhesive layers 2 are projected slightly from the conductive metallic foils 1 in the cross section of the coil winding body 5. A flat coil 10 cut through the electric discharge machining has a high conductor occupation factor and excellent efficiency. When the cut coil 10 is machined to a three-dimensional configuration, it is machined easily to a desired three-dimensional configuration because the adhesive layers 2 are brought to a semi-rigid state. Accordingly, a three-dimensional coil having the high conductor occupation factor can easily be manufactured with superior yield. The layer insulation of the conductor metallic foils 1 is ensured, thus hardly generating defective short circuits, etc., thereby improving reliability.

Title: Control device for speed change of automatic transmission of vehicle
Inventor: FUNATO MASAYOSHI
IPC: B60W10/02
Filed: 1987-07-09
Abstract: PURPOSE:To lower pulsation at the time of an on-off control by adjusting the draining speed of a shift valve to be lower at least while a returning means is functioning than the other times. CONSTITUTION:Since the engaging pressure of a frictional engaging device 102 having an accumulator 103 is gradually increased at the time of speed change while also gradually increasing an output shaft characteristic, an FCU 84 drives a solenoid S1 to turn a shift valve 101 on and off, returning it several times to the opposite speed-changing operation side to drain an engaging oil pressure, thereby, suppressing increase in the output shaft torque in the rear stage of speed change. At the time of this on-off control, an oil passage 108 to a drain control valve 130 is brought to an orifice 114 side due to rise in engaging oil pressure, to suppress the draining speed of the shift valve 101 to be low. Thereby, pulsation at the time of the on-off control can be suppressed to be low while rapidly carrying out the draining at the time of ordinary speed change as used to be.
