Title: Fault point locator
Inventor: YAMADA YUTAKA
IPC: H02H3/40
Filed: 1988-07-27
Abstract: PURPOSE:To locate a fault point economically at a high reliability by performing an outputting being switched with the results of a gauge mark of a fault point based on a comparison between each circuit current and a criterion value for the presence of a fault current. CONSTITUTION:When a fault F occurs in a circuit L1, a signal is outputted based on circuit currents I1 and I2 from an input circuit 1 and a partial voltage PD of a power source voltage V. Fault locators 4 and 5 using a shunt ratio method and an impedance method output the results A nd B of locating a fault point to respective AND circuits 7 and 8. Comparators 2 and 3 compare current values I1 and I2 with a criterion value K. Breakers CB11 and CB12 are at a 'making position', I1>K and I2>K are given previously. Therefore, an OR output 6 is zero and the results A of the location obtained by the shunt ratio method are outputted via the AND circuit 7 and an OR circuit 9. When one of the breakers is at a 'breaking' position, I1<K or I2<K is given and the OR output 6 is produced and the results B of the location as obtained by the impedance method are outputted via the AND circuit 8 and the OR circuit 9. This eliminates a large error in the location thereby enabling economical location without use of a signal of the breaker on the opposed end side.

Title: Waveform shaping device in disc reproducing device
Inventor: YAMAZAKI SHIYOUHEI
IPC: G11B7/005
Filed: 1982-10-26
Abstract: PURPOSE:To reproduce accurate and precise bit information from a disc by shaping the waveform of the reproducing bit information from the disc on the basis of the comparison with a reference level based upon mean voltage. CONSTITUTION:The reproduced bit information from the disc is integrated by an integrating circuit 53 through a level comparator 52 and outputted as mean level information. An arithmetic circuit 54 calculates the difference between the mean level information and an intermediate value of rectified waveform values 1, 0 when the duty ratio of reproduced signals through voltage dividing resistors R1, R2 is 50% and outputs a level comparison reference value for the circuit 52. Therefore, the 50% duty point of the reproduced signal becomes a reference point for waveform shaping even when a bias is applied, so that the point at the waveform shaping by the bias is not changed. Consequently, the bit information can be reproduced precisely and accurately from the disc without influence to bias variation.

Title: Flow control device
Inventor: NAKAMURA KUNIO
IPC: F24F13/08
Filed: 1984-09-07
Abstract: PURPOSE:To realize a horizontal deflection of an exhaust port flow at a wide angle without largely decreasing the flow amount by constituting the exhaust port side wall of an air conditioner of curved surfaces curved outwardly to form right and left guide walls and disposing drift vanes the curvature of which is reversible between both guide walls. CONSTITUTION:The flow in the vicinity of guide walls 8 adheres to the guide walls because the flow causes a Coanda phenomenon by drift vanes 6a in the vicinity of the guide walls 8 and 8. Hence, a wide angle drift becomes possible with a low pressure loss. On the other hand, the flow in the vicinity of the center of an exhaust port 5 spaced apart from the guide wall 8 is not affected by the side wall adherence effect but advances straight. In a case where the air conditioner is installed at the right-hand corner of the room, a rotary pin 6e is changed to be inserted into a fitting hole 9e2 at the center with respect to the drift vane 6 in the proximity of the right-hand guide wall 8a, while with respect to the drift vane 6 in the proximity of the left-hand guide wall 8b the rotary pin 6e is replaced to be inserted in a fitting hole 9e1. As a result, over the width direction of the exhaust port 5, it is possible to realize a straight line flow in the proximity of the right-hand guide wall 8a, a gentle left-hand deflected flow in the proximity of the central part and a large left-hand deflected flow in the proximity of the left-hand guide wall 8b with a small pressure loss.
