Title: Semiconductor manufacturing equipment
Inventor: KATO SUNAO
IPC: H01L23/50
Filed: 1987-01-08
Abstract: PURPOSE:To obtain a semiconductor manufacturing equipment, the precision of irradiation of which is improved and the treating time of which per lead frame can be shortened, by using a table, on which the lead frame is placed, as an NC control table and bringing the number of high-pressure water injection nozzles to one or more per IC package. CONSTITUTION:A lead frame 1 placed onto an NC control table 7 is carried up to sections under high-pressure water injection nozzles 4a-4d, the NC control table is moved so that high water pressure is made to collide with sections where a burr between leads and a surface burr are generated, and the flash among the leads and the surface flash are removed simultaneously by high- pressure water flows 5a-5d. Since the high-pressure water injection nozzles 4a-4d have the high pressure of injection water and one injection nozzle corresponds to one package 2, the NC control table 7 is moved in the vertical direction of the lead frame 1 in order to remove the flash among the leads and the surface flash corresponding to one package, thus simultaneously taking off the flash among the leads corresponding to one lead frame and the surface flash on one surface of the lead frame.

IPC: F15B13/044
Filed: 1980-01-11
Abstract: PURPOSE: To prevent leakage of fluid from a valve part completely by operating both slide valve part and valve part for controlling an output port in linkage to the operation of a bobbin.  
     CONSTITUTION: The bobbin 20 operates to the right in proportion to the value of impressed electric current and the proportional operation of the valve part 26 unified with that of the bobbin 20 opens proportionally the effective opening area of an opening 28, allowing transmission of the fuel in a space 19 to a space 27. In addition, the jet valve part 42 of a valve member 41 following to the operation of the bobbim through a spring 40 is separated from a corresponding sheet 43, while a projecting valve part 42 opposed to the taper-shaped sheet 43 increases the jet opening area, enabling the jetting of the fuel. Therefore, the leakage of the liquid from the valve part 42 is prevented completely by the function of the bobbin 20.

Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To provide an air flowmeter in which output noise is reduced and the measurement accuracy of the rate of air flow is improved by utilizing a bent pipe placed to the air intake system of a motor vehicle. SOLUTION: An air flow meter 100 is arranged in a region of a bent part 9 between an upstream straight pipe and a downstream straight pipe on the outer peripheral side where the velocity of air flow is faster than at the conduit center of the bent part 9. The entrance part 100a of the sub-channel 3 of the air flow meter 100 is opened toward the straight pipe located upstream to the bent part 9 of an air intake system, and its exit part 100b is opened toward the straight pipe located downstream to the bent part 9. As the entrance part 100a directly receives dynamic pressure from the upper stream of the bent pipe and the stable flow of air is achieved because of the high velocity of air flowing into the inside, it is possible to improve the measurement accuracy of the rate of air flow and to reduce the output noise.

Filed: 1987-01-09
Abstract: PURPOSE:To decrease erasure crosstalk and to narrow the gap for high recording density forming by forming an air gap by a notch slot to an intermediate part of the coupling face of magnetic cores coupled to each other. CONSTITUTION:A notched slot 14 is formed to the intermediate part of a face formed by bonding I-shaped cores 10a, 12a back to back. Then both ends that is, a front part 16 faced to a magnetic recording medium and a rear part 18 which is its opposite side are directly bonded and then incorporated. Coils 20, 22 are wound respectively to legs of a read/write magnetic core 10 and an erasure core 12 and a back core 24 is mounted to the rear side of the core 10. Since the air gap is formed by the notch 14 in this way, the magnetic interference between the magnetic cores 10, 12 is prevented. Then erasure crosstalk is decreased. Moreover, the gap is narrowed due to the high recording density formation.

Filed: 1986-01-10
Abstract: PURPOSE:To make it possible to accurately detect the rotational speed of a motor, by obtaining a first pulse train using a pulse wheel and generating a second pulse train having a known cycle shorter than the cycle of the first pulse train. CONSTITUTION:The light from a light emitting part is intermittently incident to a light receiving part by the rotation of a pulse wheel 54 to output a pulse train from a pulse generator 56. The first pulse train (PL1) from the pulse generator 56 is inputted to the input terminal Pi of CPU62. A reference pulse generator 58 outputs a second pulse train (PL2) to a counter 60 which in turn counts the number of pulses of the pulse train PL2 to apply the pulses to the input terminal Pd of CPU62. Then, the pulse train PL1 proportional to the rotational speed of a motor 12 and having a large cycle is obtained and the pulse train PL2 having a known cycle shorter than the cycle of the pulse train PL1 is generated. Next, the number of pulses of the pulse train PL2 generated during one cycle of the pulse train PL1 are counted to calculate the cycle of the pulse train PL1 and the reciprocal of this cycle is multiplied by proper function to obtain the rotational speed of the motor.

Filed: 1996-01-11
Abstract: PROBLEM TO BE SOLVED: To increase the driving speed and output torque while enhancing the reliability of circuit by setting the Zener voltage of a Zener diode connected in parallel with a switching means between the counter electromotive force induced in each phase of a synchronous motor and the maximum rated voltage of switching means. SOLUTION: Control signals 101-104 for a synchronous motor are inputted to the base of transistors 401-404 which generate drive signals ϕ1-ϕ4 being connected with the terminals of synchronous motor. Zener voltage of Zener diodes 411-414 is set higher than the counter electromotive force being induced in the motor coil but lower than the maximum rated voltage of transistor switching elements 401-404 for turning on/off the excitation of motor coil. Excess energy of a motor coil being turned off is transferred to other coil of same phase wound reversely and canceled by a forward current flowing through that coil thus quickening the rising of current.
