Title: Distance measurement equipment
Inventor: TAKAGI MASAAKI
IPC: G02B7/32
Filed: 1983-02-24
Abstract: PURPOSE:To distinguish the distance measurement condition with a stable operation and a simple composition by a method wherein a light emission device is excited to emit pulses of a specific frequency and a band pass filter circuit is provided to a circuit system which processes the output of a photodetecting device and the characteristics of the circuit is varied in a certain period and when one of the outputs of a light variation device circuit reaches a specific value another output condition is distinguished. CONSTITUTION:When the power is applied to each part of the circuits, FF33- 35 are released from reset and clock pulses are generated by the operation of OSC1 and, at the same time, the output of a time formation circuit 2 is reversed to ''H'' level for a period of t=25ms. Therefore, during that period only, the clock pulses pass an AND-gate 3 and, corresponding to that, the conductive and non-conductive stages of a transistor 4 are repeated so that an IRD5 emits light pulses. The light given by the emission of the IRD5 is reflected by the measured object and detected by SPDs 6 and 7 and the output of the detected light at the points (a) and (a') is generated superposed by the D.C. component of a natural light as shown by A. The output at the points (b) and (b') behind A-C amplifier circuits 8 and 9 is appeared amplified as shown by B.

Title: Detection of minute pit in silicon wafer
Inventor: MORITA ETSURO
IPC: G01R31/26
Filed: 1990-02-08
Abstract: PURPOSE:To detect minute pits on a silicon wafer by a method wherein the number of pits on the surface of the silicon wafer after a cleaning operation is measured by using a particle counter and the size of the minute pits and their number are detected on the basis of the number of cleaning operations executed until the pits can be measured. CONSTITUTION:Since an ammonia-based cleaning liquid has a prescribed etching action, minute pits on the surface of a silicon wafer are grown by executing a plurality of cleaning operations. The grown minute pits are measured by using a well-known particle counter. Their measuring operation is repeated; the growth amount of the minute pits per cleaning operation is computed; the distribution of numbers and sizes of the minute pits before the cleaning operation is detected from the growth amount. As a result, the distribution of minute pits which could not be measured by conventional methods can be measured on the silicon wafer manufactured by a pulling method. Thereby, it is possible to obtain a method to detect the minute pits and to accurately evaluate the quality of a crystal of the silicon wafer.

Abstract: PURPOSE: To set the rotational speed of a fan to the absolute minimum speed and to reduce the noise thereof by detecting the temperature of an object to be cooled and controlling the rotational speed of the fan based on the detected result of the temperature. CONSTITUTION: As for a liquid crystal projector device 1 constituted so that a lamp 6 and liquid crystal display panels 16-18 are cooled by using the fans 10 and 23, the temperature of the objects to be cooled are respectively detected by temperature sensors 33 and 34 and the rotational speed of the fans 10 and 23 are controlled based on the detected result of the temperature. That means, the absolute minimum low rotational speed of the fans 10 and 23 are held within such a range that the temperature of the lamp 6 and the panels 16 and 17 or the liquid crystal display panel 18 detected by the sensors 33 and 34 do not become over the prescribed temperature by a system control circuit 36.  Therefore, the fans 10 and 23 are rotated by reducing the rotational speed within the necessary and sufficient range immediately after a power source is turned on and under an environment that the temperature of external air is low. As the result, the noise thereof is reduced.

IPC: H04B1/707
Filed: 1994-02-28
Abstract: PURPOSE:To generate a spread code by the use of a simple configuration and implement inverse spread spectrum by using the code. CONSTITUTION:A phase of a reception signal subject to spread spectrum processing is compared with a phase of an output signal from a 1st multiplier 18 at a phase comparator 13. An output depending on the phase difference is fed to a VCXO 15 via an LPF 14.

The generated spread code is multiplied by an output signal of the VCXO 15 with a 1st multiplier 18 and the product is applied to the phase comparator 13. Thus, the spread code is synchronously with the reception signal and the spread code and the 2nd multiplier 19 are multiplied at a 2nd multiplier 19, in which inverse spread spectrum processing is implemented.

Title: Gas laser system
Inventor: KAKIZAKI KOJI
IPC: H01S3/0977
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To enable the discharging width dimemsion to be controlled without replacing main electrodes even if the main electrodes are worn out for expanding the discharge starting width dimension, by controlling the width directional dimension of the main electrodes in auxiliary ionization. SOLUTION: When main electrodes 2, 3 are worn out, the interval of a pair of shielding members 18 is set up to be the dimemsion D2 almost equal to the starting width dimension of initially measured main discharge to be auxiliary ionized. The width dimension d3 of the main discharge at that time is almost equal to the width dimension d1 of the main discharge in the initial stage. In other words, even if the main electrodes 2, 3 are worn out proportionally to the time they are used, the beam sectional shape of the laser beams can be sustained in almost specific shape, by controlling the sectional shape of the main discharge by changing the width dimension of the X rays auxiliary ionizing the discharging space by the shielding members 18, thereby extending the life time without immediately replacing the main electrodes 2, 3.

Here, it is so arranged that the focusing section 6 is shifted by an angle lest a projection image to the circuit board 5 of the optical axis thereof should coincide with the direction of a diffraction light generated from a main pattern on the circuit board 5. This enables higher separate detection rate of a foreign matter.

Title: Method and apparatus for making slice
Inventor: NANTO HIROSHI
IPC: G01N1/06
Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To stretch a slice flatly to receive the same by a tape even if the bonding strength of the tape is low. SOLUTION: Negative charge is applied to the surface of a solid sample by an electrode 14 and a tape 21 is positively charged by an electrode 13 and a cutter 31 is moved by a cutter feeding motor 34 to perform slicing. When the cutter 31 strikes against the solid sample 10, the output of a load detector 40 increases and a slicing start detector 41 detects the start of slicing. A control device 42 receives a signal from the detector 41 to lower the generated torque of a servo motor 28 by a servo drive unit 43 to lower the tension of the tape 21. The tape 21 adheres to the surface of the slicing start portion of the solid sample by the lowering of the tension of the tape to certainly receive the slicing start portion of a slice. Thereafter, the tape 21 is tensioned by raising the generated torque of the servo motor 28 to certainly bond the slice to the tape 21 in a flatly stretched state.
