Title: Centralized supervisory system
Inventor: NOJIRI TETSUO
IPC: H04B1/74
Filed: 1988-03-22
Abstract: PURPOSE:To economically improve the reliability of the title centralized supervisory system by assigning the supervision of all sections to the supervisory equipment of one terminal station when a communication line is not in fault and supervising them dividedly by the supervisory equipments of both terminal stations when the communication line is in fault. CONSTITUTION:A supervisory equipment 2 of the nearby terminal station supervises all sections when a communication line 10 is normal.

Title: Current control method for motor-driven power steering
Inventor: TAKANO AKIO
IPC: B62D6/00
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To stabilize a steering wheel to return automatically with simple, low-cost constitution by maintaining a motor current to zero before the return of a torsion angle of a torsion bar to zero, and making a backward current of such a degree as not to cause the reverse rotation of a motor, flow to the motor at a time point of the torsion angle when the motor current becomes zero. SOLUTION: When a steering wheel of an automobile or the like is steered, the torsion of a torsion bar fitted to a steering shaft is detected by a torsion sensor, and vehicle speed is detected by a vehicle speed sensor to control a motor current of a motor-driven power steering by a computer part on the basis of these detection signals. At this time, the motor current is maintained to zero before the return of a torsion angle to zero, and a backward current of such a degree as not to cause the reverse rotation of a motor is carried before a time point of the torsion angle reaching 1.5 deg.-2.0 deg.. After making the backward current flow in a zone from this time point until the torsion angle reaches 0.2 deg.-0.3 deg., the backward current is continuously carried in a zone from this time point until the torsion angle becomes zero. The steering wheel therefore returns automatically.

Title: Semiconductor diode
Inventor: YANADA SHIYUUJI
IPC: H01L29/861
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To prohibit the operation of a parasitic bipolar transistor and to realize a low-WF semiconductor diode by a MOS transistor without changing the manufacturing technique of a conventional semiconductor diode by a method wherein the gate of the MOS transistor is connected with the drain of the transistor and a bulk region is connected with the drain via a resistor. SOLUTION: A gate 103 of an N-channel MOS transistor 101 is connected with a drain 105 of the transistor 101 and a bulk region 104 is connected with the drain 105 via a resistor 102. In this case, when it is thought that this semiconductor diode is a semiconductor diode using the MOS transistor, the drain 105 corresponds to an anode and a source 106 of the transistor 101 corresponds to a cathode. When a positive voltage and a negative voltage are respectively applied gradually to the drain 105 and the source 106, a diffused semiconductor diode exists between the source 106 and the bulk region 104. When a voltage between the drain 105 and the source 106 is a voltage of 0.6V or lower, for example, a potential difference between the source 106 and the bulk region 104 is also 0.6V or lower. Therefore, there is no current, which is made to flow through this junction part consisting of the drain 105 and the source 106. A parasitic bipolar transistor is not actuated in the range of this voltage.

Title: Method of arranging shim for liquid-crystal display cell
Inventor: BURUUNO BUINOOZU
IPC: C08L51/00
Filed: 1992-03-24
Abstract: PURPOSE: To arrange a shim so as to be evaded from an intersecting part between a row and a column and a transistor(TR) part and to prevent shims from being closely arranged by arranging each shim by electrostatic sputtering until a pixel is boosted to voltage capable of inducing a charged shim. CONSTITUTION: An addressing TR is loosened by applying about 10V plus voltage to a row Li in order to apply minus potential to a pixel Pij and a column Cj is polarized to -10V e.g. Since the TR is conductive, the potential of the column Cj is moved to the pixel Pij. Plus potential is stored in the row Li and minus potential is stored in the column Cj and the pixel Pij. A plus-charged ball B is projected from a sputtering nozzle 20 and attracted to the pixel Pij and the minus-charged column Cj and repulsed from the row Li. Thereby the ball B cannot be arranged on the intersecting part between the row Li and the column Cj and on the TR.

Abstract: PURPOSE:To obtain a regeneration picture excellent in wide employment environmental temperature with no deterioration in other characteristics such as sensitivity, after image and resolution by restricting the constitution of film thickness of the third layer made of an alloy or a compound of photoconductive elements of Zn, Te and In. CONSTITUTION:A film made of a substance having a bigger band gap than CdTe is formed on a glass substrate 1 having a transparent conductive film 2 as the first layer 3, the film made of a substance mainly consisting of CdTe is formed on said first layer as the second layer 4, the film made of (ZnTe)1-X (In2Te3)X (but 0<=X<=0.1) is formed on said second layer as the third layer 5 and the thickness of the film of said third layer (ZnTe)1-X(In2Te3)X is made to be 1.6mum-2.4mum. As the target voltage value, wherein a signal current has a tendency of saturation and no baking generates, becomes still lower while the target voltage value, wherein point cracks of white points generate, becomes still higher, voltage tolerance becomes broad thus to obtain excellent picture quality having no baking and point cracks of white points inspite of wide employment environmental temperature.

Abstract: PURPOSE: To reduce the number of parts thereby to simplify the circuit construction by generating the function waveforms of the respective orders of a Walsh rectangular function at a single output line through the time sharing treatment.  
     CONSTITUTION: The clocks of an integer frequency of a fundamental frequency of a musical sound corresponding to the key depression from a tone clock generating circuit 2 are frequency-divided by a counter 4 into data selecting signals. The clocks thus divided by a counter 40 are fed to a Walsh function generating circuit 5 so that the Walsh function is impressed in a time-sharing manner to a logic circuit 7 through a data selector 61 in synchronism with the tone clocks. On the other hand, a circuit 7 is supplied with a coefficient corresponding to the envelope time according to a key depression through a data selector 62 which is controlled by the data selector signals from the counter 4 as well as a coefficient generating circuit 3 so that the circuit 7 feeds the time-shared musical waveforms coming from the composed waveforms of the respective orders of the Walsh function to an accumulator 8, a rack circuit 9 and an A/D converter which are connected through a single line. As a result, plural parallel circuits can be dispensed with, and the number of parts is reduced to simplify the construction.
