Title: Line flow fan shape inspection device and shape inspection method thereof
Inventor: NISHINO HIROHISA
IPC: F04D29/30
Filed: 1998-08-04
Abstract: PROBLEM TO BE SOLVED: To accurately detect defects and the like of a fin by detecting the distance to each fin across the entire surface thereof with a variety of detecting means and judging whether the outer shape of each fin is good or bad based on the detected wave shape thereof. SOLUTION: Changes in distance of a line flow fan 1 to, i.e., position of, a fin 1b are detected optically across the entire surface of the fin 1b by a plurality of detecting means 6 comprising a laser displacement meter disposed corresponding to each run on the outside periphery of each line flow fan 1. The wave shape from the shape of each fin 1b is calculated based on the thus detected wave shape. Then, the calculated wave shape from the shape of the fin is compared to the wave shape from the shape of a non-defective product set beforehand. When there is no deviation at the highest point of the wave shape from the shape of the fin, the investigated line flow fan 1 is judged to be non-defective.  When there is deviation at the highest point of the wave shape from the shape of the fin, the investigated line flow fan 1 is judged to be defective because a defect results from a large drop during change over of the fin 1b.

Abstract: PURPOSE:To realize frequent synchronous repetition of ultrashort light pulses in a stable manner by setting the optical path length including a sub-loop to the value obtained by arbitrarily dividing the length of a laser resonator into parts of the same length. CONSTITUTION:A fiber laser device is provided with a branching coupler C4, an optical path length adjustor K and a sub-loop LO4 consisting of an optical fiber SF which connects the coupler and the adjustor.

Title: Ultrasonic motor
Inventor: MYOGA OSAMU
IPC: H02N2/00
Filed: 1992-07-29
Abstract: PURPOSE:To control the increase in temperature due to the heat generation of an sliding part and improve the life, by forming grooves on both sides of the proximity of the mutual sliding part of a rotor and a stator and forming a hard amorphous carbon film on the sliding surface. CONSTITUTION:Grooves 13 and 14 are formed on the sides of a sliding part 15 of a rotor 11 and a stator 12. The grooves 13 and 14 are formed to the proximity of the sliding part 15 of the rotor 11 and the stator 12. If the grooves 13 and 14 are formed to the sliding part 15, the wear becomes remarkable on the grooves 13 and 14 and as a result, the purpose cannot be attained. Also, a hard amorphous carbon film containing a hydrogen atom of 10 to 30 atomic% is formed on at least one sliding surface of the rotor 11 and the stator 12, and a silicon film is formed between the sliding surface and the hard amorphous carbon film. Thus, since the heat generated in the sliding part 15 is radiated from the groove part of the sides of the rotor 11 and stator 12, the increase in temperature due to the heat generation of the sliding part 15 can be controlled. Further, when forming the hard amorphous carbon film on the sliding surface, the resistance to wear is improved and when also forming the film on the sides, the resistance to wear is further improved.

Title: Grinding pellet
Inventor: KANEKO DENJI
IPC: B24D3/00
Filed: 1985-10-05
Abstract: PURPOSE:To obtain a fine surface roughness, by dispersing two kinds of abrasive grains having different grain sizes into a binder to stabilize the grinding degree of the outer surface of a workpiece without the outer surface of the workpiece being scratched. CONSTITUTION:Since a second abrasive grain 8 having a smaller particle size has a role of a cushion, and therefore, there is no risk of scratching a workpiece 3 due to coming-off of a first abrasive grain 7 which is mainly used for grinding. The surfaces pellets 2 are dressed by the second abrasive grain together with grinding particles, and therefore, it is possible to carry out a stable grinding process until a fine surface roughness is obtained without the pellet 2 surface being clogged.

Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To enable practical, very low-noise and low-vibration crushing work by providing a chisel part of a striking piston with a control mechanism by which the striking piston is reversed from lowering to rise a designated position according to a position for striking a matter to be crushed. SOLUTION: When an upper pressure chamber 5 is again communicated with a low pressure port by switching a control piston 12, as the lower pressure chamber 4 is high pressure, a striking piston 2 is raised. Further, the pressure chamber 27 of a pilot valve 13 becomes low pressure and the pressure chamber 28 is high pressure, so that the pilot piston 14 is again returned to the initial position. Hereinafter similarly the operation is repeated. As the pilot valve 13 is operated according to a pressure chamber at the time of striking, even if a material 6 to be crushed is separated downward from the lower end of the main body 1, a striking piston 2 strikes in that position to be switched from lowering to rising surely. Accordingly, it is possible to obtain a practical low noise hammer.
