Title: System for vapor-phase crystal growth provided with vertical reactor tube
Inventor: ISHIKURA TAKURO
IPC: C30B25/14
Filed: 1984-10-11
Abstract: PURPOSE:The titled device where a barrier wall is set to the reactor on its top so that no gap is formed between the reactor and the wall top and wall comes down near the periphery of the base to intercept the gas flow into the outside and the inside of the wall, thus enabling more accurate control in the composition on the growth layer. CONSTITUTION:A barrier wall 4 is set in the upright type of reactor tube 1 so that the wall is held to the reactor on its wall top without gaps and the wall comes down near the outer periphery of the base 2. The gas comes down from the inlet 1a, reacts above the base 2 and a part of the product deposits on the base 2. A part of the rest gas rises up, while the other part comes down and is exhausted from the reactor. The gas rising up is intercepted by the barrier wall 4 and comes down along the wall 4 and join in the gas flow from the base toward the tube wall. Thus, the gas rising along the wall of the reactor tube is exhausted outside the reaction system almost without mixing into the gas flowing down from the inlet 1a. The mobility of the growth layer formed in the device is larger than that formed in a conventional device and can have rapid change in composition.

Title: Distance measuring device
Inventor: IZUMI HIROYUKI
IPC: G01C3/06
Filed: 1989-08-19
Abstract: PURPOSE:To perform measurement without an error by comparing the difference of measured value obtained when the size of a sport is changed by changing a distance between a light source and a light projecting lens or the irradiation angle of a light beam with a reference value, detecting the missing of the spot even when the missing occurs in the spot and correcting an obtained result. CONSTITUTION:A projected light beam L emitted from a light emitting element LED passes the light projecting lens 10 and is reflected on an object M, then a reflected light beam S is made incident on a photodetector PSD by a light receiving lens. In order to change the diameter of the spot 50 generated by irradiating the object M with the projected light beam L, a piezo-electric element 6 for changing the distance between the lens 10 and the LED is attached to the lens 10. The lens 10 is laterally moved by the piezo-electric element 6 and the spot 50 on the object M is made 51, for instance, or large 52. By changing the irradiation angle of the beam L, the size of the spot 50 can be varied. In the case that the difference of output obtained when the size of the spot is changed exceeds the range of set value, the obtained result is corrected by judging there is a large possibility that an erroneous distance is obtained or a warning is given to accelerate to perform measurement again.

Title: Ultrasonic flow rate and flow velocity meter
Inventor: SHIMIZU KAZUYOSHI
IPC: G01F1/66
Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To improve measurement accuracy by setting an ultrasonic vibrator to a conduit of a nearly rectangular section having a pair of opposite sides of a breadth similar to or not larger than a size of the ultrasonic vibrator, and propagating ultrasonic waves uniformly at each area of different flow velocities in a fluid. SOLUTION: The breadth of the narrower inner wall face of a rectangular conduit 10 is set to a value similar to a size of ultrasonic vibrators 11a, 11b. The ultrasonic vibrators 11a, 11b are set on a pair of narrower confronting outer wall faces to be inclined to an axis of the conduit via wedges 12a, 12b. Many areas of different flow velocities are present in a lateral cross section of the conduit 10. Ultrasonic waves radiated from the ultrasonic vibrator 11a are propagated as nearly plane waves within the entire areas of the different flow velocities because a breadth of the conduit 10 is reduced almost to a breadth of the ultrasonic vibrator 11a. As a result, measured values of the flow velocities of all areas become a uniformly averaged value and approximate to a true value.

Title: Magneto-optical modulation device
Inventor: TOGAWA MASAYUKI
IPC: G02F1/09
Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To enable magneto-optical modulation without attaching a magnet to a specimen by changing a magnetic field given to a magnetic field generation means by a magnetic substance, and detecting magnetic field change from the direction of polarization of light transmitting a magneto-optical effect element. SOLUTION: When a specimen such as the gear of a magnetic substance is put in the neighborhood of a detection head part 10, a magnetic field given to the magneto-optical effect element 12 of a magnet 20 is changed, the magnetic field intensity of an orthogonal component to an optical axis is reduced, and the direction of inside magnetization is directed to the direction of the optical axis in response to self magnetization. Thus, a polarization face is rotated by generation of Faraday effect to be reflected on a reflection mirror 13 and a linear polarization which a polarizer 11 takes out by being emitted from a semiconductor laser 15 is made incident on the polarizer again. At this time, the polarization direction is rotated up to 90 degrees to be orthogonal, and an amount of light is zero without transmitting the plarizer 11.  When the gear is more distant, the influence for a magnetic flux weakens, the polarization face is not rotated, the linear polarization transmits the polarizer 11 and a light receiver 16 outputs the receiving signal of a prescribed level. Thereby magneto-optical modulation is enabled without attaching a magnet to the specimen.
