Filed: 1987-06-26
Abstract: PURPOSE:To measure the erosion depth of a target with high reliability by providing a part for measuring the erosion depth of a target in a high-vacuum sputtering chamber. CONSTITUTION:Light is obliquely projected on the erosion region 2 of the target 1 from a light source 3, and the light reflected from the erosion region 2 is detected by a unidimensional CCD sensor 4.

Abstract: PURPOSE:To improve the mass-producibility of electrostatic capacity type reproducing styluses used for video disk players, by using at least one of SiC, Bn and transparent carbon for the tip part of the stylus. CONSTITUTION:On a C-surface sapphire single crystal (5mm. thickness) 8 as a substrate, an SiC thin film (3mum thickness) 9 is formed (a) by RF sputtering and a keel part 10 is formed (b) by photoetching; and the substrate is cut (c) by a multiwire saw along a cutting line 11, and polished (d) until the cut surface is coincident with the flank of the keel part 10, and Ti is vapor-deposited on the polished surface to about 0.2mum to form an electrode 12, thus obtaining a reproducing stylus. The said method facilitates wafer processing by ordinary IC manufacture process and improves work precision, and there is no limitation on the base substrate. Using a BN thin film or transparent carbon film instead of the SiC thin film results in nearly the same effect.

Abstract: PURPOSE:To enable a multilayer printed wiring board to be lessened in permittivity and enhanced in reliability by a method wherein a first and a second insulating layer are provided adjacent to each other providing a gap between them, a metal layer is provided to each of the opposed surfaces of the adjacent insulating layers, and the metal layers partially confronting each other are joined together by plating. CONSTITUTION:The copper circuit pattern 4b of a double-sided printed wiring board 5b is so shaped as to confront the copper circuit pattern 4a of a double-sided printed printed wiring board 5a like a reflected image. The two double-sided printed wiring boards 5a arnd 5b are so aligned as to make their copper circuit patterns 4a and 4b confront each other interposing a gap between them, and the printed wiring boards 5a and 5b are subjected to copper electroplating as kept in a state that they are confronting each other.

IPC: G01R31/26
Filed: 1994-07-12
Abstract: PURPOSE:To enable nondefective chips to be sorted out by interrupting the direct currents of input circuits during a sorting test, and passing the direct currents during normal operation. CONSTITUTION:A normal operation mode is switched to a sorting test mode and vice versa by control signals D, DN which are produced by inverters 31, 33, respectively. During normal operation, high-level (H) and low-level (L) signals are provided respectively to inputs 1, 2, whereas a signal lower than the threshold of the inverter 31 is provided to the input 2 during a sorting test using a static current. The signal D varies from L to H and the signal DN from H to L. The signals D, DN turn off p-type MOS transistors 15, 19, 13, 17, 11 and n-type MOS transistors 27, 5, 9 so that direct currents from a high voltage source VDD are all shut off. When the performance of each MOS transistor is sufficiently high, the currents consumed are small enough so that a sorting test can be conducted by measuring the currents.

IPC: G01P5/02
Filed: 1989-06-22
Abstract: PURPOSE:To detect a tilt angle and acceleration while improving shock resistance by providing a load mass which floating in a sealed container filled with noncompressive liquid and a means which detects its displacement or a force applied to the mass. CONSTITUTION:In the noncompressive liquid 11 charged in the completely sealed container 10, the hollow sphere 12 which has less mean density than the liquid 11 floats and is coupled with the container bottom 14 by an arm 13. A tilt angle detecting circuit 15 is provided on the outside top surface of the container 10. Then when the container 10 slants at an angle theta to the horizontal surface, the sphere 12 shifts in position by buoyancy in proportion to the tilt angle thetaand the circuit 15 detects that. When acceleration is generated, the displacement of the sphere 12 by a force in the opposite direction from the acceleration is detected to measure the acceleration. Consequently, the tilt angle and acceleration can be measured only by altering the constitution of a detecting means.

Title: Driving apparatus of arched gear
Inventor: HIDA TOSHIO
IPC: F16H19/00
Filed: 1978-12-27
Abstract: PURPOSE: To automatically stop operation in a region where the engagement of two pinions causes an interference during a reverse-directional operation so that any possible damage on the gear may be prevented when an arched gear is operated in a normal or a reverse direction with the assitance of the pinions.  
     CONSTITUTION: During its normal-directional rotation, if an arched gear 11 were stopped in a halfway position and reversing switch S 2  turned on, the said gear won't rotate because of non-excitation of electromagnetic contactor coil MR 1  for reverse rotation due to the disconnection of either of detector switches KS 1 WKS 4 . However, if electromagnetic contactor coil FR 1  for reverse rotation, is excited by means of reversing switch S 2  in a position where pinions 12, 13 are completely engaged with each other and the contact points of all the detector switches KS 1 W KS 4  are closed, electric motor 14 is in a state of reverse rotation. This results in the opening of the contact point of detector switch KS 4 , freeing electromagnetic contactor coil MR 1  for reverse rotation from excitation with the subsequent stopping of the arched gear 11.
