Title: Identification method of wafer
Inventor: SAKAGUCHI MITSUSACHI
IPC: H01L21/68
Filed: 1997-02-12
Abstract: PROBLEM TO BE SOLVED: To identify the wafer position with high precision in relation to the identification method for identifying the wafer position by detecting a plurality of identification points previously positioned. SOLUTION: The distances from the predefined identification points PA1-PA3 to the edges E1-E3 when a wafer 1 is installed on a regular position are previously stored as the reference values LC1-LC3. Next, the actual values LB1-LB3 to be the distances from the actual identification points PB1-PB3 to be actually processed for identification to the installed wafer 1 are computed while comparing the reference values LC1-LC3 with the actual values LR1-LR3. Next, when the actual values LR1-LR3 are smaller than the reference values LC1-LC3, the actual identification points PB1-PB3 are shifted to one line below the cut line for reidentification processing. Contrary to this, when they are larger than the reference values, the actual identification points PB1-PB3 are shifted to one line above the cut line for reidentification processing.

Title: Method and apparatus for detecting horizontal displacement of excavator
Inventor: ARAI MASAO
IPC: E21B47/024
Filed: 1988-02-09
Abstract: PURPOSE:To raise the accuracy of detection by a method in which the displacement of central position of a wire connected to an excavator in continuously detected and at the same time the time is detected by clock pulse and converted into distance. CONSTITUTION:When a laser oscillator 8a moves while giving off laser and passes by a start edge 20a, laser is reflected on a photo receiver 8b to become laser-on, where a reference point is set by the receiver 8a. When the oscillator 8a comes to the position of a wire 5, laser turns off, the time from the reference point is detected, and the distance L1 from the reference point is calculated by a recorder. When the oscillator 8a moves, laser turns on, and also when it comes to the position of an end edge 20b, laser turns off. The diameter L2 of the wire 5 and the distance between the edges 20a and 20b are calculated by the recorder and the distance L3 from the wire 5 to the edge 20b is also calculated. After the center position of the wire 5 is obtained from the distances L1, L2, and L3, the same operations are repeated to detect the center position of the wire 5 continuously for detecting the horizontal position of the excavator.

Title: Air-fuel ratio control device of electronic control fuel injection type internal-combustion engine
Inventor: GOKAN YOSHIAKI
IPC: F02D41/14
Filed: 1985-02-18
Abstract: PURPOSE:To improve fuel consumption by providing an after starting injection amount arithmetic means for outputting after starting injection amount obtained by multiplying starting time basic injection amount by after starting correcting coefficient to a drive pulse signal output means and by performing stable warming up operation after starting. CONSTITUTION:A starting time basic injection amount setting means 6 sets the starting time basic injection amount T based on the engine cooling water temperature Tw. After starting, an injection amount arithmetic means 9 outputs the starting time basic injection amount T while passing time Tas after starting of an engine is smaller than a predetermined time. While, after the predetermined time, the starting time basic injection amount T is multiplied by after starting correcting coefficient Kas under the operation condition and the after starting injection amount Tas obtained is output to a drive pulse signal output means 6 instead of output of an injection amount arithmetic means 3. Thus, stable warming up operation after starting is made to improve fuel consumption.

Filed: 1993-01-26
Abstract: PURPOSE:To suppress the progression of oxidation even in corrosive environment and to obtain good adhesiveness with rubber by applying a triazole compd. on a metallic wire-shaped body. CONSTITUTION:The metallic wire-shaped body is subjected to a rust preventive treatment by applying the triazole compd. (more particularly preferably tolyltriazole) expressed by formula thereon. The metallic wire-shaped body subjected to plating is immersed into an aq. soln. added with the triazole compd. or the triazole compd. is added into a lubricant in the case of wet process drawing and this soln. is applied on the metallic wire-shaped body. The triazole compd. is adsorbed on the plating metal such as zinc and exhibits a rust preventive effect.

Title: Demodulator circuit for self-clocking information signal
Inventor: SUGIURA YOUJI
IPC: G11B20/14
Filed: 1979-03-13
Abstract: PURPOSE:To secure the demodulation for the data signal based on the clocks which are generated in the unit number corresponding to the measurement result of the inverting intervals of the self-clocking information (SCI) signal. CONSTITUTION:In case the FM-modulated SCI signal is demodulated, the signal inverting interval is either T0 or 2T0. And one unit of pulse/NC is generated based on latch signal output L1 in case the quantization is given to T0; while two units of pulse/NC are generated based on latch signal output L2 in case the quantization is given to 2T0 respectively. When the FM modulation is carried out, JKFF92 is reset by means of the output of NAND91 to which pulse X3 and latch signal output L2 are supplied. And the pulse/NC is divided into two parts by JKFF92, and the /Q output turns to clock RCL'. When output L1 is used for the data and clock RCL' is used for the clock which operates on the rise of RCL', the original digital data signal is demodulated.
