IPC: G02B26/10
Filed: 1987-06-25
Abstract: PURPOSE: To lessen the deterioration in the gain in the high-frequency range of a moving body part and to execute stable tracking control by using the mutually induced electromotive force of a 3rd coil to decrease the mutually induced electromotive force of a 2nd coil and feeding the same negatively to the 1st coil.  
     CONSTITUTION: A reflecting means 1 and the coil 8 turn and the induced electromotive force proportional to the interlinkage speed with a magnetic gap is generated at both ends thereof and the mutually induced electromotive force is generated with a change in the current of the coil 6 if the current is impressed to the coil 6. The mutually induced electromotive force increases with an increase in the frequency. The mutually induced electromotive force similar to the mutually induced electromotive force of the coil 8 is generated in the coil 10 as well. A difference between the mutually induced electromotive forces generated between the coils 8 and 10 is obtd. and is fed back negatively to the coil 6. As a result, the stable tracking control is executed.

Abstract: PURPOSE:To obtain functions of rapid rise and high-speed breaking, by igniting a gate turn-off thyristor to supply a voltage, and by restricting a load current by the action of a reactor to extinguish the gate turn-off thyristor when a load is short-circuited. CONSTITUTION:After a control angle of a thyristor switch 11 is set and a voltage of a capacitor 14 is determined, a thyristor rectifier 17 is operated to make a current flow through a diode 15 via the primary winding 16 of a reactor 16. The value of a bias current is controlled automatically by a phase control signal sent to the thyristor rectifier 17 by a current control circuit 21 so that a current reference signal sent from a setting unit 19 becomes equal to a current signal detected by a current transformer 20. When GTO 22 is ignited under the condition, a current is supplied to a load 23. When the load is short-circuited, the diode 15 is put in a OFF state, an increase in a load current is restrained by the reactor 16, and thereby the GTO 22 is extinguished.

IPC: H04M3/00
Filed: 1993-06-29
Abstract: PURPOSE:To reduce maintenance man-hours by providing a means reading a subscriber circuit class and providing a means editing station data and holding the data tentatively, a means executing the test and a means writing the data to a database under the control of a central controller. CONSTITUTION:A central controller 1 extracts the edit result by one subscriber circuit from an edit latch means 5, selects a test procedure corresponding to the class of the subscriber destination in the mount state and starts a test execution means 6. The means 6 started from the controller 1 interrupts lines of designated subscriber circuits 2-1-2-n to give a simulating call to them. In this case, an operation control circuit 3 sends a dialing state to the controller 1. When the controller 1 recognizes the call from any designated subscriber circuit among the subscriber circuits 2-1 to 2-n to be normal, the controller 1 leaves the edit result as it is and controls the means 5 to store the result to a database 7 after re-edit as in the non-mounted state when an error is recognized. Thus, a danger of system-down on the occurrence of a fault is avoided.

Title: Base plate for firing aluminum nitride substrate
Inventor: HAYASHI TATEO
IPC: F27D3/12
Filed: 1989-06-23
Abstract: PURPOSE:To permit the firing of an aluminum nitride substrate, thin and having no warpage, without grinding it by applying the coating of a specified boron nitride film on the surface of a carbon base material. CONSTITUTION:The surface of a carbon base plate 10, having a size same as or larger than the size of an aluminum nitride form 3 to be fired, is coated with boron nitride having a thickness more than 5mum. The carbon base material 10, having the thickness of 3mm or more and preferably 5-15mm, is employed. When the thickness of the carbon base material 10 is less than 3mm, there is the possibility of warping of the carbon base material 10 itself by thermal hysteresis received upon coating the boron nitride or upon firing the aluminum nitride. On the other hand, when the thickness of the carbon base material 10 exceeds 15mm, the number of aluminum nitride forms, which can be received in a firing furnace, is reduced and the efficiency of production may be deteriorated. According to this method, the aluminum nitride form will never be adhered to a base plate even when laying powder is not interposed between the base plate and the aluminum nitride form upon firing whereby the aluminum nitride substrate, thin and having no warpage, may be manufactured without grinding it after the firing.

Abstract: PURPOSE:To improve the processing performance in automatic dial processing by sending a parameter request command in either a command format of a character synchronizing form or of a frame synchronizing form to a network controller and discriminating a command format with a dip switch based on the result of reply. CONSTITUTION:Prior to the automatic dial processing, a dial number is stored separately in work areas depending on two command formats of character synchronizing form and frame synchronizing form (S5). Then a parameter request command is publicated in the character synchronizing form (S6). The setting state of the command format by a dip switch of a network controller is discriminated from the result of reply (S7). When an interrupt of reception data read enable takes place, the automatic dial processing is implemented in the character synchronizing form (S8) and when the interrupt does not take place, the automatic dial processing is implemented in the frame synchronizing form (S9). Thus, the processing performance of a device such as an intelligent MODEM is improved.
