Title: Surface acoustic wave device
Inventor: NISHIDA NAOKI
IPC: G02F1/335
Filed: 1998-06-04
Abstract: PROBLEM TO BE SOLVED: To obtain a surface acoustic wave device, which is capable of suppressing the generation of reflection waves at a substrate end face causing spuriousness, eliminates the possibility of deterioration with lapse of time and facilitates processing by forming a substrate surface between electrodes and the end face of the substrate as a rough surface which is gradually roughened toward the end face. SOLUTION: The IDTs (comb-shaped electrodes) 15, 16 are formed on a piezoelectric substance surface 11 made of LiNbO3 . The surface of the substrate 11 is formed as a rough surface 13 by injecting particles thereto by using a sand blaster into the stage of a mother substrate (wafer) formed with the IDTs 15, 16 in order to prevent the reflection of the surface acoustic waves from the end face 12 of the substrate 11. The rough surface 13 is a region between the IDTs 15, 16 and the end face 12. The rough surface 13 is gradually roughened toward the end face 12 from the part adjacent to the IDTs 15, 16. To obtain such a rough surface, the particles of different grain sizes are ejected dividedly to a number of stages at moving of the sand blaster.

Title: Laser oscillator
Inventor: IKEMOTO NORIO
IPC: H01S3/03
Filed: 1979-12-05
Abstract: PURPOSE:To expand a stable region of glow discharge and increase laser output by forming a projection onto an inner wall of a discharge tube making up a gas flow path reaching the low voltage electrode side from the high voltage electrode side. CONSTITUTION:A projection 20 for forming an eddy, which projects in the inflow direction of gas, is built up onto an inner wall surface at the high voltage electrode 11 side of a discharge tube 2. Consequently, the gas flowing into the discharge tube 2 as shown in the arrow head 23 through by-gas flowing holes 13 flows along a fixed section 21, collides with a bottom section with roundness of a groove 22 made up by the projection 20, and is brought to an eddy condition as shown in the arrow head along a shape of the groove 22. Thus, a gas current near to the projection 20 is agitated and the velocity of flow is weakened, sections where the gas current separates from a tube wall surface are extremely reduced, and a nondischarge zone is hardly formed by the formation of a vacuum zone. As a result, an unstable region of glow discharge becomes very narrow.

Filed: 1996-06-18
Abstract: PROBLEM TO BE SOLVED: To prevent a passenger conveyor from starting if such failure as the handrail belt stall detecting device of a passenger conveyor generates the same output as normal handrail belt speed happens. SOLUTION: When a start switch is turned on, a contact Ryb for auxiliary output signal of a handrail belt stall detecting device 30 is closed and other safety guard contact is closed, therefore, the starting signal 15 of a passenger conveyor 15 is inputted. At the time of starting the passenger conveyor, handrail belt speed abnormality is outputted by turning off an output relay Ry by the action of a delay circuit 31 for a prescribed time t1. The operation of the output relay is checked by a passenger conveyor electric control circuit through the contact Ryb for the auxiliary output signal, and the passenger conveyor is then started. Therefore, the passenger conveyor cannot be started under such a condition as the handrail belt stall detecting device fails, thus it is possible to improve safety of the passenger conveyor.
