Title: Phase-locked loop circuit device
Inventor: TANAKA KATSUAKI
IPC: H03L7/10
Filed: 1983-05-13
Abstract: PURPOSE:To prevent the unlocking of a PLL because of application of power or other external disturbances by detecting the unlocking of the phase-locked loop or the state in the vicinity of the unlocking based on a control voltage applied to a voltage controlled oscillator from a low-pass filter and controlling the control voltage so as to be led within the locking range. CONSTITUTION:When the PLL circuit is operated normally, since an output voltage of the 1st voltage comparator 13 is kept to a low level Vcc1(-) and an output voltage of the 2nd voltage comparator 14 is kept to a high level Vcc2 (+), diodes 25, 26 as selective current supply circuits are kept both turned off. If the control voltage Vc exceeds a lock range upper limit voltage V4 because of power application or other external disturbance or the like, the output voltage of the 1st voltage comparator 13 reaches the high level voltage Vcc1(+), the diode 25 is turned on and the control voltage Vc of the output stage of an operational amplifier 7 is decreased. If the control voltage Vc is decreased less than a lock range lower limit voltage V1 due to any cause, the output voltage of the 2nd voltage comparator 14 is inverted into the low level voltage Vcc2 (-), the diode 26 is turned on, a negative voltage is applied to the low-pass filter 2, causing a current to be extracted from the low-pass filter 2 through a resistor 27.

Title: Detection of fault section of power transmission line
Inventor: MATSUSHITA TSUTOMU
IPC: H02H7/26
Filed: 1988-04-04
Abstract: PURPOSE:To obtain high sensitivity for a detected line decreased in an influence from its up and down lines by setting a current detector vertically to the ground on the electromagnetic center line of the right and left detected lines. CONSTITUTION:In the case of a steel tower having a line 1 comprising each phase A1, B1, C1, line 2 comprising each phase R1, S1, T1, line 3 comprising each phase A2, B2, C2 and a line 4 comprising each phase R2, S2, T2, the lines 1, 2 arrange their current detectors P1, P2 and voltage detector K1 and the lines 3, 4 arrange their current detectors P3, P4 and voltage detector K2, as shown in the drawing. Since the current detectors P1, P2 are placed in a position on the symmetrical center of the lines 1 and 2, electromotive force by induction is not generated in the normal time but generated being unbalanced in the abnormal time. When a ground fault is generated, the voltage detector K1 generates an output by electrostatic induction with the ground. Also for the lines 3, 4, the similar action is performed.

Filed: 1983-05-16
Abstract: PURPOSE:To display a high quality picture by electrostatic recording, and also to execute easily copying by forming an electrostatic latent image inverting left and right on the outside of a transparent dielectric sheet made adjacent to develop. CONSTITUTION:A transparent dielectric sheet 11 extended to rollers 2, 3 is made parallel and adjacent to each other by rollers 2', 3'. A left and right inverted electrostatic latent image C formed on the sheet 11 by a write electrode 4 is developed by a developing device 5 to obtain a toner visible image D. The image D is an inverted image, but when it is seen from a display part 8, namely, the direction as indicated with an arrow of a thick line, it comes to be seen from the rear side of the image D through two transparent sheets 11 to obtain a display picture of an erect image. In case of obtaining a copy, the image D is transferred to paper 9 by using a transfer device 10. Since the image D is an inverted image, the transfer image obtains an erect image, and a normal recording.

Title: Automatic controller
Inventor: SUKIMOTO YASUYUKI
IPC: G05B7/02
Filed: 1984-04-25
Abstract: PURPOSE:To attain the follow-up to the output operation quantity of automatic control with an optional changing factor without using a capacitor, etc., by giving automatic control to a control subject by an operation quantity defining the change of the control operation quantity as an allowable variation range when the difference of the control operation quantity exceeds the allowable variation range stored in a memory means in a switch mode to the automatic control from the manual control. CONSTITUTION:The manual control is switched to the automatic control by a manual/automatic switch part 11. In this case, the process quantity given from a control subject 1 is detected by a sensor 2. The previous output operation quantity is stored in an RAM8 via an amplifier 3 and an A/D converter 4. A CPU6 calculates the difference between said operation quantity and the output operation quantity obtained in a switch mode. This difference is compared with the allowable variation range stored in the RAM8. When the difference of output operation quantity exceeds said variation range, the change of the output operation quantity is defined as a variation range to give control to the subject 1 via an output operation part 9. Thus the precise control is possible with an optional changing factor without using a capacitor, etc. at a control output terminal.

Title: Valve system
Inventor: SHIDA TOSHIMITSU
IPC: F01L1/26
Filed: 1989-04-04
Abstract: PURPOSE:To evenly transmit the downward force exerted to a roller by a cam onto tow valves by rocking the abutting part of the cam around the axis being parallel to the axis connecting the middle point of the spindle end surfaces of two engine valves with the rocking fulcrum. CONSTITUTION:A roller 10 and a roller case 50 abuttedly engaging with a cam 1 constitutes a cam abutting part which is rockable around the axis being parallel to the axis connecting the middle point of the spindle end surfaces of two engine valves 6a, 6b with the rocking fulcrum of a rocker arm 4. Thereby, even if a clearance h is caused between the engine valves 6a and 6b to incline the rocker arm 4, the roller case 50 rocks around a rocking axis 51 so as to offset the inclination of the rocker arm 4. As a result, the roller 10 rotatably supported by the roller case 50 is brought into surface abutting always without being inclined to the cam 1, even if a clearance h is caused between the engine valves 6a and 6b. Thus, such a moment that causes the unbalance of force can be hardly produced.
