Title: Method for evaluating vibration resistance characteristic of filament wire material and tungusten wire for high vibration resisting filament
Inventor: FUKUCHI KANJI
IPC: G01N3/18
Filed: 1989-07-05
Abstract: PURPOSE:To reduce the measuring errors of the amount of deformation and to reduce the dispersion of the results of quality evaluation by performing the secondary heating with the specified amount of current for a wire material which has undergone the first heating, and measuring the intervals at the central part of a test piece before and after the heating. CONSTITUTION:A test piece 3 formed in a V-shaped hair-pin state is vertically suspended and fixed with a pair of clamps 5 in a closed container 9. Cooling pipes 4 are inserted in the container 9. A weight 6 is suspended at the lower end of the test piece 3. Non-oxidizing gas is made to flow in the container 9. A current which is 65% of a fusing current for a filament wire material constituting the test piece 3 is conducted for 30 seconds. Thus the first heating is performed. Then, the weight 6 is removed, and a current which is 95% of the fusing current of the wire material is conducted for 300 seconds. Thus, the second heating is performed. Then, the opening width of S of the test piece 3 is measured and compared with a reference value So. Thus the vibration resisting characteristic of the wire material 3 is judged.

Title: Method and device for detecting liquid in vessel
Inventor: ROBAATO EI RAPETEINA
IPC: G01F23/22
Filed: 1982-10-04
Abstract: Method and apparatus for detecting the presence of liquid in a container includes an elongate rod (or other vibratory element) which extends into the container to contact liquid when a certain amount of liquid is present, a piezo-electric element coupled to the rod on the exterior of the container to cause the rod to vibrate in response to electrical signals and to produce electrical signals indicative of the amplitude of vibration of the rod, and circuitry for producing a utilization signal when the electrical signals produced by the piezo-electric element indicate that the amplitude and duration of vibrations of the rod are below some threshold level. Such vibrations fall below the threshold level when the rod contacts liquid in the tank and so production of the utilization signal is an indication that liquid in the container has reached a certain level.

Abstract: PROBLEM TO BE SOLVED: To provide a pachinko game machine capable of attracting players' interest stronger than conventional ones. SOLUTION: When a ball passes a liquid crystal display start hole, the passing speed of the ball is detected by a light sensor 15a and a second passing detecting section 15.

Abstract: PURPOSE:To improve loading and unloading efficiency in a bucket elevator for excavating and conveying a bulk cargo by pivoting a bucket on a chain with three links provided with a spring interposed, thereby releasing a bucket with more than a fixed excavating force. CONSTITUTION:When a bucket 16 driving in B direction is subjected to excavatting resistance FH and push-up force FV during excavation, a link 12 is pivoted upward on a shaft 19, and respective link members 20, 22 are bent at a shaft 23 to release the bucket 16 upward as shown by a chain line.

Further, the posture for fitting the bucket 16 is set so that a suitable front rake alpha is obtained at a proper excavation resistance FH. In this arrangement, a shock imposed upon the chain is reduced, and the chain can be driven at high speed to improve loading and unloading efficiency.
