Title: Damper pulley and manufacture thereof
Inventor: MATSUNO MITSUYOSHI
IPC: F16H55/36
Filed: 1988-09-30
Abstract: PURPOSE:To increase the compressibility on the edge surface part of a rubber elastic body by forming a projection part which projects to the rubber elastic body side through the plastic working at least on one edge surface part of a rim part opposed to the edge part of the rubber elastic body and pressing the rim part toward the outside from the inside by a shaping roller. CONSTITUTION:A projection part 3b which projects to a rubber elastic body 6 side is formed at least on one edge part of a rim part 3 opposed to the both edge surfaces of the rubber elastic body 6 or at least on one edge part of an inertia mass 5. The compressibility at least on one edge part of the rubber elastic body 6 is increased by the projection part 3b, and the abrasion of this part can be prevented. Therefore, the outside slip-off of the rubber elastic body 6 is prevented, and the slip-off of the inertia mass 5 can be prevented.

Title: Digital arithmetic circuit
Inventor: OMOTANI YOSHIRO
IPC: H03G11/00
Filed: 1986-10-15
Abstract: PURPOSE:To attain the charasteristic, which executes the desired clipping operation, with a few logic circuits and a few control circuits by detecting an input value by means of a zero detection circuit and specifying an output value by means of an output switch circuit. CONSTITUTION:The input value of N-bits (N : optional integer greater than zero), which is expressed by natural binary numbers, is inputted, and M-bits (M : optional integer greater than zero and not greater than N) from the most significant bit of the input value is inputted. The zero detection circuit 4 judges whether the most significant bit and the subsequent M-bits of the input value are logical value '0'. When the result of the judgement says that all of the M-bit are the logical value '0', the output switch circuit 6 regards the constant of N-bits '2N<->M' as an output value. If the result of the judgement says that one of the M-bits is not logical value '0', the output switch circuit regards the input value as an output value. Thus a few of control circuits can execute the clipping operation.

Abstract: PROBLEM TO BE SOLVED: To dispense with the treatment of exhaust ozone by mixing the gas containing undissolved ozone separated from water to be treated in an oxidizing reaction tank and accumulated in a gas phase part with water to be treated on the way introduced into an adsorbing tank. SOLUTION: The water 100A to be treated in a raw water tank 100 enters an oxidizing reaction tank 5 through an introducing pipe 1 but, at this time, ozone-containing gas is mixed with the water 100A to be treated by an ejector 2.

Filed: 1995-08-21
Abstract: PROBLEM TO BE SOLVED: To simultaneously improve the safety and a beautiful sight by preventing nearly all of workpieces from being exposed to the ground surface in planting a tree. SOLUTION: A root ball is set in the bottom of a drilled hole and, e.g. four tension rods 13 are inserted into a bonding rope 16 having a length to be a considerably larger diameter than that of a tree to form a loop of the bonding rope with a wire clip. Bonding plates 12 are subsequently brought into close contact with the upper side and lateral face of the root ball and fixed thereon and fitting rods 14 are fitted thereinto. The looped bonding rope 16 is integrated with the bonding plates 12 and bonding rods 15 are then fitted into holes of the bonding plates 12 on the sides. Resistance piles 10 are inserted into the respective bonding rods 15 and shallowly inserted into the hole bottom to ensure the upright standing state. When the resistance rods 10 are successively placed, the looped shape of the bonding rope 16 is slightly deformed.  When the resistance piles are renewed and then further successively placed, the bonding ropes 16 are tensed into a square state and the root ball is kept in a more powerfully fixed state with the resistance piles 10, bonding plates 12 and bonding rope 16.

Title: Rotary compressor
Inventor: SHIMIZU NOBUHIRO
IPC: F01C21/08
Filed: 1984-11-21
Abstract: PURPOSE:To reduce the necessary starting torque and starting vibration by installing a pressurizing means for applying the pressure higher than the pressure of a compressor in stop from outside the compressor and increasing the force for pressing a vane onto a rolling piston, when the vane is started. CONSTITUTION:When a solenoid valve 16 is opened simultaneously with the start of a compressor, the coolant in a tank 15 heated by a heater 16 is introduced into a vane groove 11 through a pipe 14, and the vane 4 is pressed onto a rolling piston 3. When the compressor is put into stable operation, and a difference between the discharge pressure and a suction pressure is generated, a solenoid valve 17 is closed, and then the vane 4 is pressed furthermore onto the rolling piston 3 by the above-described differential pressure. Therefore, a spring for pressing the vane 4 onto the piston 3 can be removed. Therefore, also the need for a spring accommodating hole can be eliminated, and the strength of a cylinder 2 can be increased. Further, since the pressing of the vane 4 on starting is performed by liquid, torque can be reduced, and the necessary starting torque can be reduced, and also the starting vibration can be reduced.

Abstract: PURPOSE:To improve diffusing air temperature distribution by extending the sidewall of a tank disposed at the front face side of a heat exchanger to the end position of a fin nearest to the tank, and entirely covering a space between the tank and the adjacent fin. CONSTITUTION:The front side sidewall 18a of an upper tank 18A is extended downward over the height level of a sheet metal 30 over the entire width, and arrives at the end height level of a fin 28 nearest to the tank 18A. The extended part 18b shuts off an air flow from a direction of an arrow A into a small space B interposed between the fin 28A and the metal 30. The extended part 12b of the sidewall 12a of the tank 12A is connected integrally with the extended part 18b. Further, the entire side sidewall 16a of a lower tank 16A is extended upward over the height level of the metal over the entire width, and the part 16b shuts off an air stream from the direction of an arrow A into the small space between the metal and the fin nearest to the metal. Accordingly, only the air heat exchanged with the fins is diffused through its core from the back surface side of a heat exchanger 10A.
