Abstract: PURPOSE:To separate and select detected diffracted interference light independently by providing at least diffraction grating in each couple of mutually opposite areas of two bodies so that light which is projected after traveling through the couple of areas becomes diffracted light having a two-dimensional distribution. CONSTITUTION:A mask 34 is arranged at a specific Z-directional interval with a wafer 33, areas 11, 12, and 13 are prescribed at specific positions of the mask 34, and areas 21, 22, and 23 are prescribed at specific positions of the wafer 33 opposite those areas. Stripped or checked diffraction gratings are arranged in those areas and when the gratings are irradiated with two beams f1 and f2, the diffraction gratings project three diffracted interference light beams IG, IW, and IW having the two-dimensional distribution. The two light beams IW and IM which have specific degrees and are used for positioning are separated and detected independently of other diffracted light beams and detected, and consequently, the mask 34 and wafer 33 can be positioned with high accuracy irrelevantly to their interval.

Filed: 1992-01-17
Abstract: PURPOSE:To provide one balanced photodetector having a satisfactory S/N by increasing an AM noise effect even when disturbance is applied to the two output fibers of a photocoupler. CONSTITUTION:A photocoupler 3 synthesizes outputs from a local light emitting source 1A and an intensity modulated signal light source 2.

An amplifier 5A and a variable gain amplifier 5B amplify the outputs of the photodetectors 4A and 4B. Band pass filters 6A and 6B pass only the intensity modulated frequency signals 12D and 13D. A subtracter 7 subtracts the intensity modulated frequency signals 12D and 13D. A control circuit 8 adjusts the gain of the variable gain amplifier 5B and equalizes the amplitudes of the amplified signals 12C and 13C. Band pass filters 6C and 6D pass the amplified signal 12C, AM noise 22C, amplified signal 13C and AM noise 23C. A differential circuit 9 synthesizes the amplified signals 12C and 13C and cancels the AM noise 22C and 23C.

Abstract: PROBLEM TO BE SOLVED: To smoothen the starting by setting a compression stroke injection mode for performing the injection of fuel by a fuel injection valve in compression stroke in starting, and starting the fuel injection in the compression stroke injection mode at the point of time when the cranking reaches a prescribed rotating speed. SOLUTION: An ECU 14 controls the feed power to an electric motor 4 to increase the output, and drives an actuator 12 to connect a transmission clutch 10. It further starts the cranking of an engine 2 and judges whether the cranking rotating speed reaches a prescribed rotating speed or not.

Title: Method for detecting gap between mold registering surface of transfer mold
Inventor: ITO KATSUAKI
IPC: B29C45/02
Filed: 1988-02-05
Abstract: PURPOSE:To certainly detect a degree of hermetical sealing, by a method wherein air is discharged from or supplied to a clamped hermetically sealed mold to measure the flow rate of said air. CONSTITUTION:A lead frame R is placed on a lower mold 2 and, after an upper mold 1 and the lower mold 2 are clamped, a resin tablet A is placed in a pot 6 and a plunger 7 is allowed to fall. The plunger 7 is allowed to fall to close the opening of the pot 6 and the air in a cavity 5 is reduced in pressure and sucked through an air pipe 9(contrarily, compressed air may be supplied to the cavity 5 from the air pipe 9). When a gap is present between mold registering surfaces, air is penetrated in the cavity 5 from the outside through the gap when the air in the cavity 5 is reduced in pressure and sucked (contrarily, compressed air may be supplied) and, therefore, the internal pressure of the cavity 5 does not change. This pressure change is observed by a pressure gauge 10 to accurately detect the presence of the gap.
