Title: Automatic controlling method
Inventor: SAKASHITA RIYUUJI
IPC: G05D9/12
Filed: 1982-03-05
Abstract: PURPOSE:To obtain a feedback circuit which prevents the overshoot of the value to be controlled and stabilizes it quickly to the target value, by setting the width of a blind sector provided contiguously to the target value at a large value at first and then gradually at a small value. CONSTITUTION:A control part 1 supplies a target value 1a to a comparator 2 and at the same time feeds an action command 1b to a timer 3. The comparator 2 compares the value 1a with a controlled variable 4a of a controlled system 5 which is detected by a sensor 4 and then delivers a deviation 2a. A blind sector setting part 6 sets the width alpha of a blind sector when the part 1 is active to feed it to a comparator 7 and then sets the width beta(<alpha) of the blind sector when the timer 3 gives a command 3a after the prescribed time to feed it to the comparator 7. The comparator 7 gives an action command 7a to a controller 8 to control 8a the controlled system 5 as long as the deviation 2a does not exceed the blind sector alpha at first and then the blind sector beta respectively. In such a way, it is possible to prevent the overshoot of the value to be controlled and stabilize quickly said value to the target level.

Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To send a ringer tone that is confirmed from a wide area by activating a ringer circuit with AND between a coincidence signal from a comparator circuit and a call signal from a telephone line. SOLUTION: A call signal sent from a telephone line 3 to a connection device 1 at the arrival of an incoming call is fed to a radio telephone set 2 from a control section 11 via radio sections 12, 22 and a ringer circuit 23 being controlled, a ringer tone is sent from a speaker section 2. Simultaneously the tone is given to an incoming call detection circuit 14 and an AND circuit 18. A comparator circuit 13 receiving a detection signal measures an input time of an incoming call detection signal, compares it with a preset timer value, and when they are matched with, a coincidence signal is given to an AND circuit 18.  The AND circuit 18 sends an AND signal of the call signal received from the telephone line and the coincident signal to a ringer circuit 15, which sends a ringer tone activated by the AND signal via a speaker section 16 to inform the user of the arrival of an incoming call.

Title: Cathode-ray tube
Inventor: KANBARA EIJI
IPC: H01J29/50
Filed: 1987-02-20
Abstract: PURPOSE:To focus electron beams not to have spherical aberration components so that a spot diameter of the electron beams on a target can be made small to improve resolution by forming a divergent lens which has positive spherical aberration between an electron beam generation part and a main focusing lens. CONSTITUTION:This cathode-ray tube has the following units: an electron beam generation part where electron beams are generated, controlled, and accelerated, and a main focusing lens part 39 which has positive spherical aberration where the electron beams emitted from the electron beam generation part are focused on a target. When a divergent electron lens 38 which has positive spherical aberration is formed between the electron beam generation part and the main focusing lens 39, the positive spherical aberration of the main focusing lens part 39 can be canceled by that of the divergent electron lens 38. Accordingly, the electron beams are focused not to have spherical aberration components so that a spot 41 of the electron beams on the target can be made small to improve resolution.

Title: Insulated gate field effect transistor
Inventor: OOHATA TAMOTSU
IPC: H01L29/10
Filed: 1982-03-09
Abstract: PURPOSE:To enable to obtain the high withstand voltage of an insulated gate field effect transistor by a method wherein a low impurity concentration layer and a high impurity concentration layer are formed by performing diffusion of a source region or a base region two times. CONSTITUTION:Deep diffusion is performed at low surface concentration to form the first source region layer 13a coming in contact with the base region 2, and shallow diffusion is performed after formation of the layer 13a at high surface concentration sufficiently higher than the former to form the second source region layer 13b coming in contact with the layer 13a. By forming the source region like this, diffusion impurity concentration at the base region 2, especially at the part near the surface of the substrate is reduced according to the distance from the edge of a diffusion hole. As a result, because the total quantity of impurities of the region 2 is increased, and extension of a depletion layer to the base layer to be generated when a drain voltage is applied is reduced, enhancement of the withstand voltage can be attained. Moreover by shortening channel length still more, mutual conductance can be enlarged, and formation of the transistor as to have large current capacity can be attained.

Filed: 1993-02-25
Abstract: PURPOSE:To allow turn ON/OFF of a switching element by allowing a capacitor in a charge pump circuit to be charged from the start of outputting waveform. CONSTITUTION:A resistor 10a is connected in order to charge a capacitor 3b in a charge pump circuit upon throw-in of power thus producing a desired waveform from the start of outputting waveform.

Title: Voltage adjusting device
Inventor: INUI MASAHIRO
IPC: G05F1/10
Filed: 1998-02-18
Abstract: PROBLEM TO BE SOLVED: To provide a voltage adjusting device capable of reducing tap switching frequency by reducing useless tap switching. SOLUTION: Deviation voltage ΔV and a deviation integration value Vh calculated by a voltage adjusting relay in a master substation are estimated from a voltage change in the receiving end of a slave substation 3B. Fuzzy inference is executed by using a fuzzy rule setting up the estimated values of the deviation voltage ΔV and the deviation integration value Vh as antecedent part variables and setting up a sensitivity correction coefficient Kf for correcting the operation sensitivity of a voltage adjusting relay Ry2 as a consequent part variable and a membership function regulating the degree of each variable suited to a fuzzy label to find out the coefficient Kf.  Since the operation judging level of the voltage adjusting relay Ry2 in the slave substation is corrected by using the sensitivity correction coefficient Kf, the variation of secondary side voltage of the slave substation and tap switching frequency can be reduced.

Title: Medium detecting system
Inventor: JOHNSON STEVEN M
IPC: B65H5/06
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To provide a medium detecting system, which detects the position of a medium relative to a roller in a medium sending mechanism, at a low cost. SOLUTION: A microprocessor 45, which issues a command to a DC motor controller 40 that exercises the drive control of a DC motor 15, issues a command to the controller 40 in correspondence to a signal from a tachometer 35, which detects the revolving speed of the motor 15. When there is no medium 30, a receiving roller 20 rotates faster than a receiving roller 25 (The receiving roller is driven at a constant speed by another motor). When the medium 30, which is sent at a constant speed by the sending roller 25, is taken in by the receiving roller 20, the revolving speed of the receiving roller 20 is decreased because of frictional force. In responce to this, the DC motor 15 is controlled so that the torque for rotating the receiving roller 20 is decreased. When the medium 30 is released from the sending roller 25, the revolving speed of the receiving roller 20 is increased.  In responce to this, the motor 15 is controlled so that the speed of the receiving roller 20 is increased.
