Title: Simplified stabilizing construction method for slope
Inventor: YAMADA YASUHIRO
IPC: E02D17/20
Filed: 1996-04-09
Abstract: PROBLEM TO BE SOLVED: To simplify construction for the stability of a slope without needing large-scale construction so as to shorten a construction period and reduce construction cost. SOLUTION: Drilled holes 2 are formed at appropriate spaces in the ground of a slope. Both ends of rustproof tension material 1 are bent, and the end parts of a plurality of tension material 1 are inserted in one drilled hole 2. The other end of each tension material 1 is inserted in the separate drilled hole 2, and the intermediate part is extended between the drilled holes 2, 2 so as to be extended along the slope. A hardener is filled in the drilled hole 2 to fix the tension material 1, and the slope is held down by the intermediate part of the tension material 1. A keep member is interposed between the slope and the intermediate part of the tension material, and the hardener is sprayed thereon.  Or the tension material 1 is folded in two and inserted in the drilled hole 2, and a reinforcement or tension material is passed through a bent part near the ground surface and stretched over the drilled holes 2. There is therefore no need of large-scale construction dispensing with form construction, troublesome arrangement of reinforcements and a member such as an anchor head so as to simplify construction.

Abstract: PURPOSE:To prevent the adhesion of powder to the pipe walls of an exhaust pipe by making the exhaust pipe have a double structure composed of a porous inner pipe and an outer pipe having capillaries, and by causing an inert gas to flow from the capillaries through the pipe wall of the inner pipe to the inside of the inner pipe, and exhausting it along with an exhaust gas during processing. CONSTITUTION:For example, if the bore diameter of an outer pipe 12 is 30mmphi and that of an inner pipe 11 is 20mmphi, the bore diameter of capillaries 20 is made to be about 3mmphi and several capillaries 20 of that size are provided at an exhaust pipe section having a double pipe structure. And the inner pipe 11 is a porous one having multiple pores, and it has innumerable minute pores of 0.5-1mmphi. A double-layer exhaust pipe section like this is provided, and nitrogen gas is caused to flow from the capillaries 20 while a CVD device is being operated. As a vacuum exhaust pump provided at the tip of this exhaust pipe is evacuating, then, the nitrogen gas which entered from the capillaries 20 to between the outer pipe 12 and the inner one 11 is exhausted along with a waste gas being exhausted from the CVD device side. On that occasion, powder contained in the waste gas does not adhere to the pipe wall of the inner pipe 11, and is exhausted along with the nitrogen gas which has passed the pipe wall of the inner pipe 11.

Abstract: PURPOSE:To ensure a quantitative supply of bean sprouts to a measuring bucket for an accurate measurement thereof by possessing a conveyor belt which rises from a bean sprout reservoir located at a lower position at an angle with respect to the measuring bucket and which is provided with a plurality of pins thereon, and a loosening means which is located adjacent to a discharge portion at the upper end of a take-up conveyor and which is provided with a plurality of pins thereon. CONSTITUTION:Bean sprouts are lifted from a reservoir, conveyed while being retained by pins 2 on a conveyor belt 3 and fallen off from an upper discharge end thereof. A drum 8 located adjacent to the discharged end of the conveyor and provided with pins 7 thereon rotates to thereby loosen the bean sprouts and at the same time the pins on both the conveyor and drum pull and scatter the bean sprouts to pieces right and left and drop the same broken up in a uniformly scattered state. Both the pins 2 and 7 are arranged in such manner that the end portions thereof engage one another to some length and both this length and the pin length are selectively set at proper values according to the goods to be conveyed. When the weight of the goods which is preset at a smaller value than a value required in the measurement is read on a measuring bucket 19, a take-up conveyor 1 is lowered in its speed, whereby the bean sprouts are conveyed in a piecemeal manner and hence dropped into the measuring bucket 19 in a piecemeal manner.

Filed: 1993-04-16
Abstract: PURPOSE:To improve riding comfort by providing set damping force selecting function for selecting the set damping force of suspension mechanism corresponding to the computed accelerator opening speed, from a control map. CONSTITUTION:At the accelerating time of a vehicle, in the state of a gear being put in low gear such as the first or second gear speed, the change of vehicle behavior generated in association with small accelerator opening change is suppressed by switching the damping force of oil dampers 3, 7, 11, 15 into the hard state. In the state of the gear being put in high gear such as the fourth or fifth gear speed, the change of vehicle behavior generated in association with large accelerator opening change is suppressed by switching the damping force of the oil dampers into the hard state, and the change of vehicle behavior generated in association with comparatively small accelerator opening change is suppressed by holding the damping force of the oil dampers in the soft state. A squatting phenomenon of the vehicle rear part being lowered especially at the accelerating time can be thereby suppressed, and accurate anti-squatting control can be performed.

Title: Cup wheel for hard brittle substance
Inventor: SEKI YASUKAZU
IPC: B28D1/04
Filed: 1979-09-07
Abstract: PURPOSE:To prevent a hard brittle substance from being heated and damaged, by prescribing the shape of the front end of the grindstone holder of a cup wheel least the side surface of the holder should come into contact with the hard brittle substance in grinding. CONSTITUTION:The surface of the electroformed grindstone making end part 14a of a metal-made holder 14 for an electroformed grindstone is convexly curved. Abrasive grains are educed as eutectoid in a bonding material on a region 15 which extends in the center of the convexly curved surface and has a central angle theta of about 120 deg. or less. However, since abrasive grains are not sufficiently educed as eutectoid on an outer region 16 and an inner region 17, these regions 16, 17 are cut, as shown by a dotted line, so that the electroformed grindstone 18 is manufactured on only the region 15. When a cup wheel thus manufactured is used to grind a hard brittle substance such as glass, the side surfaces 16, 17 of the grindstone making part 14a do not come into contact with the hard brittle substance and do not damage it in the grinding because the side surface are cut.
