Title: Layout method of leticle and shot
Inventor: IBARAKI TOSHIAKI
IPC: G03F1/70
Filed: 1996-09-02
Abstract: PROBLEM TO BE SOLVED: To suppress the inspecting time of a reticle to the minimum, and avoid the rise of unit cost and extension of time limit of delivery of the leticle by arranging each shot on the leticle so that chips having the same pattern are aligned in line or column direction between a plurality of shots. SOLUTION: Each shot 22-24 formed of a reticle 21 is laid out so that common chips 26 constituting each shot 22-24, or the chips 26 having the same pattern, sub-chip size, and the number of arranged pieces are vertically aligned. Auxiliary pattern chips 27-32 necessary for manufacture which are formed of monitor patterns or alignment patterns are properly arranged around the common chips 26. Since the common chips 26 are arranged in the same line, the defect inspection by a conventional chip comparative inspection can be performed, and the inspecting time can be shortened.

Next, since the amplitude of the perpendicular parabolic waveform is varied by the change of the vertical frequency, the amplitude of the waveform is uniformized with a variable gain amplifier 10, then, it is inputted to the modulation circuit 14. In such a way, it is possible to always obtain the optimum correcting state of the side pin distortion in spite of the vertical frequency.

Abstract: PURPOSE:To reduce re-incident reflected rays to an optical system by the reflected rays of returned rays from the greater part of the front end face of a semiconductor substrate oppositely faced to the optical system by retreating the front end face of the substrate just under at least a laser-beam outgoing end. CONSTITUTION:In a semiconductor laser, in which a laser diode section 2 is formed onto a semiconductor base body 1, the front end face 1a of the semiconductor base body just under at least the laser-beam outgoing end (a) of the semiconductor laser is retreated to a section rearer than a laser-beam outgoing end face. The front end face 1a is formed in an optically roughened surface in the constitution. Since the substrate thickness of the semiconductor base body 1 occupies the greater part of the total thickness of the laser practically in the semiconductor laser, rays are scattered by retreating the front end face 1a and forming the front end face in the optically roughened surface in a section just under at least the laser-beam outgoing end face (a) of the front end face, thus reducing the efficiency of returned rays to an optical system, then improving a tracking error and the deterioration of C/N.

Title: Real time phase difference range-finding system
Inventor: MURAI HIROMICHI
IPC: G01S13/36
Filed: 1999-08-18
Abstract: PROBLEM TO BE SOLVED: To reduce a measurement error based on the strength change of a reception signal and to reduce distance measurement time by obtaining distance from the ratio of the DC component of the multiplication signal of transmission and reception signals to that of the multiplication signal of a signal where the transmission signal has been subjected to specific phase shift and the reception signal. SOLUTION: The oscillation (transmission) signals of both oscillators 10 and 15 are multiplied by a mixer 14 and are inputted to a multiplier 3 and a phase shifter 2. Also, the multiplication signal of a receiver 19 is multiplied by the oscillation signal of the oscillator 15 by a mixer 20, which is inputted to the multipliers 3 and 4 via an LPF 21. The multiplier 3 multiplies an input (transmission) signal from an LPF 17 by a signal (the multiplication value of the reception signal of the receiver 19 and the oscillation signal of the oscillator 15) from the LPF 21 before inputting to an LPF 5. On the other hand, a multiplier 4 multiplies a (transmission) signal obtained by phase-shifting by a specific amount using the phase shifter 2 by a signal from the LPF 21 before outputting to an LPF 6.  A divider 7 obtains the ratio of the DC components of the signal where the passage of the AC components is rejected by the LPFs 5 and 6. Distance is calculated based on the ratio.

Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To shorten processing time by specifying the Y (X) axis direction coordinate change judging method following a change in the coordinates in the X (Y) axis direction. SOLUTION: The center coordinates X0, Y0 and radius (r) of a circle are set. Then, a 1st point (X, Y) of circle plotting is found as coordinates from the origin (0, 0) and a change judging reference (e) in the Y axis direction is calculated. Whether a found current coordinate value reaches 1/8 circumference or not is judged in accordance with judgement whether X and Y coordinates reach the segment of X=Y from the origin (0, 0) or not. When the current coordinate value does not reach the 1/8 circumference, coordinates symmetrical about the segment X=Y are found based on the current coordinates and either coordinates symmetrical about X and Y axes formed by using the center coordinate value of two symmetrical coordinates as an origin and the origin (0, 0) are found.  When the deviation of the Y (X) axis direction from a value on a real circumference due to the increment (decrement) of the X (Y) axis value is larger than a reference value (e) such as a half of one display, the Y (X) axis value is decreased (increased), so that the deviation of the Y (X) axis value can easily be judged.

Filed: 1990-09-03
Abstract: PURPOSE:To make it possible to change a feeding by providing control means for changing the feeding speed in feed means when a time exceeding a time predetermined by count means for counting input time by a feed key is counted. CONSTITUTION:It is determined whether a pressing of a journal paper feed key 101 is continued or not. When the pressing of the key is completed, a high speed feeding is stopped. On the other hand, when the pressing of the key is continued, it is determined whether an output of a print detecting sensor 9 is inverted between white and black at a predetermined cycle in order to detect an end of the printing. When the printing is completed, the output of the print detecting sensor 9 becomes unchangeable and a white level is continued. In such a state, the feeding is stopped. Thus, when the journal paper feed key is pressed during a transaction, a printer feeds papers at low speed. When the pressing time exceeds 1.5 seconds, the papers, are fed at high speed.
