IPC: G01B11/02
Filed: 1986-03-25
Abstract: PURPOSE:To measure the width of the slide surface of a trolley wire while excluding the influence of support hardware for rigid body stringing by irradiating the trolley wire with luminous flux at a high angle of incidence and receiving the light at right angles. CONSTITUTION:The projection part consisting of a light source 2, a slit plate 15, and a lens 16 irradiates the slide surface 1-1 of the trolley wire 1 with luminous flux 17 to form a light belt 18. The direction of the light belt 18 is perpendicular to the wire 1 and the angle of incidence on the surface 1-1 is 60-80 deg.. A light receiving part consists of a lens 5, a slit plate 20, and a linear image sensor 19 and its photodetection angle is 90 deg. to the projection direction. The slit 20 is wide enough to cut off the unnecessary part of a real image. Then, the trolley wire moves within the range of a deviation interval H, so the projection part consists of the light source 2 which is a little bit longer than the interval H, the slit plate 15, and the cylindrical lens 16. Further, the light receiving part is so constituted by dividing the deviation width H into, for example, three in consideration of the aberrations of the lens 5 and arranging the photodetectors in the respective sections. Boundaries of the respective divided sections are put one over another through an optical system and connected by adjusting the addresses of the elements of the sensors 19a-19c.

IPC: F02D45/00
Filed: 1990-03-19
Abstract: PURPOSE:To detect the knocking coping with the kind of engine and the secular change by A/D-converting the signal of a knock sensor, storing the signal as the data train in time sequence, obtaining a plurality of frequency components through the addition and subtraction calculation of the data train, detecting the relation of magnitude from a threshold value for each component and combining the relation of magnitude of each component. CONSTITUTION:A cylinder internal pressure sensor or knock sensor detects the pressure variation accompanied with the combustion in a combustion chamber or the vibration in the generation of knocking, and the signal having a sufficient amplitude through amplification can be A/D-converted. A means for region restriction can eliminate the influence of the repetitive frequency in the frequency analysis. A/D conversion is carried out at each certain time interval, and the data train is stored, and the input signal can be analyzed in time sequence. Knocking can be detected by analyzing the frequency only for a specific frequency by analyzing the data train. The method for frequency analysis can be carried out at high speed by using only addition and subtraction calculation.

Title: Vertical pump
Inventor: YOSHIKAWA YOSHIHIKO
IPC: F04D13/00
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To control the flow rate of a pump in accordance with a water level lower than the minimum water level and permit the drain operation at a water level lower than the minimum water level without generating harmful swirl. SOLUTION: In this vertical pump, an advanced standby operation is made at a water level during pumping operation lower than one corresponding to a minimum water level WL1, below which air is inhaled from a suction bell mouse therein. The vertical pump comprises an inlet pipe with one end side thereof communicated to a casing 4 below an impeller of the pump, and the other end side thereof open to the atmosphere. By installing the inlet pipe 10 with the other end side open to the atmosphere to the side of a top end of the inside of an absorption bath, the pressure inside the inlet pipe 10 decreases according to the decrease in the water level. According to this, the intake amount inhaled into the pump casing 4 increases, and discharge amount of the pump increases. Thus rolling of air from the suction bell is thereby eliminated, resulting in prevention of abnormal vibration or noise.

IPC: G06F1/24
Filed: 1993-03-26
Abstract: PURPOSE:To minimize time required for reset by allowing an output part to turn a reset signal line to the non-active side at the time of completing a reset flag state. CONSTITUTION:A semicondictor integrated circuit (LSI) 1 receives a reset low pulse signal inputted from an external reset signal line 2 by a reset signal input part 4 to initialize its inside operation status. The input part 4 transfers control an LSI inside reset control part 6 to reset the inside of the LSI 1 and generates a reset flag setting signal to set up a flag for an LSI inside resetting part 5. Thereby an LSI inside status output part 3 is turned on. Since the output part 3 holds its ON status during the reset period of the LSI 1, the signal line 2 is fixed on a low state. When the reset flag is turned to the reset status after completing the reset of the inside, the output part 3 is turned off and an external reset signal is turned to a high level.
