Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To obtain a resistor excellent in the utilization efficiency of a metal foil forming the resistor by making substantially elliptical through holes into a belt-like resistor foil. SOLUTION: Substantially elliptical through holes 32 are made through a belt-like resistor foil 31 and the resistance is adjusted by abutting a measuring terminal 33 against the vicinity of the through hole 32. The resistor foil 31 is then clamped by thermoplastic resin films 35 while covering a part of adjacent through hole 32 and the resin 35 is integrated with the resistor foil 31 through heating of ultrasonic processing. Subsequently, the through hole 32 is punched and a terminal corresponding part is projected from the side face of the resin 35. Thereafter, the terminal corresponding part is bent along the profile of the resin 35 and plated. This structure enhances the utilization efficiency of material in producing a resistor and a highly accurate resistor can be produced.

Title: Focus control performance check disk for optical disk driver
Inventor: SHIMIZU AKIHIKO
IPC: G11B7/24
Filed: 1988-02-03
Abstract: PURPOSE:To properly judge whether a driver is proper or improper to a focus control by forming the central axis of a chucking member in inclining it to the main surface of a substrate. CONSTITUTION:A magnetic disk 15 is coupled in inclining an axis C to an axis L of a substrate 10 at a prescribed angle theta. For such a reason, a main surface H of a check disk D is inclined to a horizontal surface at the prescribed angle theta. Thus, for the focus control performance check disk of an optical disk driver, at the time of deciding the focus control performance of the driver to the inclination, a troublesome work to repeat a turntable inclining operation two times can be canceled, an influence by the dispersion of the quality of one disk adopted for the check cannot be exerted, and thereby, whether the driver is proper or improper can be decided by properly checking the focus control performance as the driver.

Title: Substrate holder mechanism and substrate spin drier
Inventor: SHIMAZU YUJI
IPC: H01L21/304
Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for replacing a comb-tooth guide for supporting the orientation flat of a semiconductor wafer in a substrate holder mechanism of a substrate spin drier. SOLUTION: An orientation flat holder mechanism for a wafer W comprises a pair of flat guides 10a, 10b combined with an orientation flat comb-tooth guide 20 disposed between them so that the bottom B of the valley V of the guide 20 may not touch the edge EF of the orientation flat. The flat guides 10a, 10b are dedicated to transmit the rotary acceleration/deceleration to the orientation flat F and to receive the impact force from the flat F, while the guide 20 functions only for blocking the wafer W from turning down. Because the edge EF of the flat F never touches the bottom B of the valley V of the guide 20, the guide is never scratched to eliminate the need for replacing the guide 10 at a high cost and much labor.

Filed: 1983-02-15
Abstract: PURPOSE:To obtain an accurate, high-precision measuring device of simple constitution by sampling and holding a signal generated by clipping the peak of a luminance signal of video at a constant voltage, and measuring a frequency after frequency modulation by said output through a counter. CONSTITUTION:The peak of the horizontal synchronizing signal of an input video luminance signal 18 is clamped by a clamping circuit 11 to the constant voltage, and the clamped luminance signal is processed by high-frequency emphasis 12. A spike pulse generated at this time is suppressed by a white clip/ dark clip circuit 13 and inpt the resulting signal 22 to a sample holding circuit 14. When a switch 20 is placed on the side of measurement of a sink chip level SCL, a sampling pulse SP generating circuit 17 outputs an SP signal 24A which synchronizes the horizontal synchronizing signal of the signal 18 except in a vertical blanking period to a circuit 14, which holds the SL of the signal 22. The SCL is converted 15 into a frequency, which is measured 16. Then, the switch 20 is placed at the side of measurement of a white peak level and an SP signal 25B is outputted from the circuit 17 to take a measurement 16 of a white peak carrier frequency.

Filed: 1988-02-04
Abstract: PURPOSE:To reduce a variation in the speed of an AC motor due to the variation in the voltage of an AC power source by providing output regulating means for correcting a conduction angle in response to the variation in the power source voltage of an AC motor. CONSTITUTION:When the voltage of an AC power source 1 is enhanced, the voltage at both terminals of a series resistor circuit 49 is raised, and the voltage VK of a capacitor 48 is enhanced. Accordingly, the conducting angle of the applied voltage of an AC motor 2 is reduced, and the increase in the rotating speed of the motor upon rising of the power source voltage is suppressed. On the contrary, when the voltage of the power source 1 is decreased, the voltage at both terminals of the circuit 49 is reduced, and the voltage VK of the capacitor 48 is decreased. Accordingly, the conducting angle of the applied voltage of the motor 2 is increased, and the decrease in the motor speed upon decrease of the power source voltage is suppressed.
