IPC: H01F7/16
Filed: 1995-07-17
Abstract: PURPOSE: To quickly and surely perform an operation by demagnetizing residual magnetism in a solenoid for driving in a short time when the operation is completed by providing a switch means connected to the coil of the solenoid in series between the power source terminals of a driving circuit for the solenoid and a residual magnetism compulsory discharge means connected in parallel with the coil. CONSTITUTION: The prescribed number of balls is ejected by connecting the tip rear part of a flow-down blocking member 22 to the tip part of the plunger 21a of the solenoid 21, turning reciprocally the flow-down blocking member 22 around a supporting shaft 24 by extending/contracting the plunger 21a, making the tip part advance in or retreat from a guide chute and permitting or blocking the flow down of the ball. A Zener diode Dz of Zener voltage higher than the peak value of a power supply voltage is connected to the driving circuit of the ejection solenoid 21 in parallel with the ejection solenoid 21. When a transistor TR2 is turned off, the Zener diode Dz functions as an energy compulsory discharge means, and the demagnetizing time of the solenoid 21 can be shortened.

IPC: H01J9/02
Filed: 1982-10-14
Abstract: PURPOSE:To focus an emitted electron beam into a uniform electron beam and obtain high intensity by oxidizing the surface of a field emitter made of a single crystal of transition metal carbide monocrystal. CONSTITUTION:A field emitter made of a single crystal of transition metal carbide is flash-heated to a high temperature in an extremely high vacuum to form a clean surface.

An automatic radial control section 8 returns the state of dialing from a channel setting section 3 to an interrupt state with a signal detection output of the nonconnect signal detection section 7, drives a dial button 4 to apply redialing. Thus, so long as the nonconnection signal detection section 7 does not detect the reception of the nonconnection signal, a telephone set 1 connects to the connection destination, and when a nonconnect signal is detected on the otter hand, the redialing is repeated for any time. Thus, the connection to the destination is attained without manual operation.

Abstract: PURPOSE:To compensate the value speed to quickly approximate the actual temperature of hot water to a target temperature by correcting the signal of the detected tempera ture of hot water based on the change rate with time at the time of the variation of pressure to operate a temperature correction coefficient. CONSTITUTION:When the operation is started, flags F1 and F2 are initialized to set '1' and '0' to flags F1 and F2 respectively, and a correction coefficient TD is set to a constant C. An actual temperature TM of hot water in a mixing water pipe 15 is detected by a sensor 18 and is supplied to a CPU in a controller 20. The CPU computes a change rate dTM/dt with time of the actual temperature TM of hot water and determines the correction coefficient TD by a prescribed processing operation. The CPU calculates a corrected temperature TM' of hot water in accordance with a formula I based on said change rate dTM/dt with time and correction coefficient TD. Next, a deviation DELTAT' of the corrected temperature TM' of hot water from a target temperature TO is calculated, and an opening/closing speed R of a valve is retrieved in a map based on this deviation. Thus, the output processing like power supply to a motor of a valve driver 21 is performed and valves 13 and 14 are driven at the retrieved opening/closing speed R.
