Title: Color locking circuit
Inventor: KANEMOTO YOSHITAKA
IPC: H04N9/793
Filed: 1981-08-21
Abstract: PURPOSE:To ensure a stable operation of a color locking circuit with no release of the color locking, by delaying the gate pulse for a prescribed time when the reproduction is started and releasing the delay when the burst signal is detected and at the same time switching the luminance signal system to the color mode. CONSTITUTION:The color video signal reproduced through a head 3 is applied to a demodulating circuit 7, and the demodulated signal is applied to an AGC circuit 10 via an LPF8 for white/black signals. For the output of the circuit 10, the horizontal synchronizing signal HD is sampled. This signal HD is applied to a gate pulse generating circuit 14 and delayed for a prescribed time to be turned into a gate pulse P. The pulse P is applied to an ACC voltage detecting circuit 16 and an APC voltage detecting circuit 17 through a delaying circuit 15 having delaying extent gamma. While the chroma signal given from an amplifier 4 is applied to both circuits 16 and 17, and the circuits 16 and 17 sample the burst signal out of the chroma signal. The contacts of switches 1 and 2 are switched to the side (b), and an LPF9 for color video signals is connected. At the same time, the circuit 15 is separated. Thus almost the center part of the burst signal can be sampled for the pulse P.

Title: Hydraulic vibrator valve
Inventor: OGATA KOUJIROU
IPC: F15B11/15
Filed: 1978-10-30
Abstract: PURPOSE: To reduce the rate pf production of a hydraulic vibrator valve, by fitting plangers with reduced diameters to both ends of main and sub spools and connecting drain chambers attached to both ends of the spools with a tank through holes in the spools.  
     CONSTITUTION: Plangers 22W25 are fitted to both ends of main and sub spools 2, 3, the diameter of plangers being smaller than that of spools to which the plangers are fitted, for applying pressure in pressure chambers 6W9 to the plangers. Drain chambers 26W29 on both ends of the spools are connected with a tank through holes 30, 31 in the spools. This reduces the discharge of a pump 14 for driving the spools 2, 3 and the pump's pressure is also reduced because the holes are short in length and the amount of oil discharged from the pressure chambers is small. This can reduce the rate of production and the power required for running the valve mechanism.

Filed: 1983-07-22
Abstract: PURPOSE:To reduce the resistance of a coil circuit and perform excellent recording and reproduction by forming the coil circuit of a thin film made of copper or its alloy, and forming a thin film of aluminum or its alloy on its one surface. CONSTITUTION:The coil circuit 3 made of copper or its alloy is laminated spirally on a lower magnetic body layer 1, and a quartz glass layer 2 constituting a magnetic gap 2 is laminated thereupon. Further, an upper magnetic body layer 5 is laminated and a low-fusion-point glass layer 7 is laminated thereupon. Then, a thin film 4 made of Al or its alloy is formed on one or both surfaces of the thin-film coil 3 to a thickness <=1/2 as large as that of the copper film. This constitution never causes layer separation, etc., due to high temperature for the annealing of magnetic poles or for depositing a protection plate on a head substrate. Further, a chemical reaction is caused on the interface between the surface oxidized layer of the Al layer and insulating layer to form a stabilized layer. Furthermore, an interlayer insulation defect due to the diffusion of copper ions on the interface between the Al layer and copper alloy layer is eliminated.

After the completion of delivery of the read-mixed concrete, water is injected into the stirrer 3 to wash away the residual ready-mixed concrete from the stirrer 3 while it is uncurled.  The device for putting this method into practice is equipped with a cool air blower 1, to which an air duct 2 is connected. Further, the opening part 2a of the air duct 2 is set to fit into the stirrer 3 for the ready-mixed concrete and thereby, the internal temperature of the stirrer 3 is maintained below about 15 deg.C by the cool air.
