Title: Torque measuring device
Inventor: YAMADA KENZOU
IPC: G01L5/24
Filed: 1981-04-22
Abstract: PURPOSE:To measure a large torque with a small rotary torque, by securing the engagement between a planetary gear and the inner and outer gears of a guide disk and multiplying the rotary torque applied to a shaft by the number of teeth. CONSTITUTION:When a grip part 26c is turned clockwise, an idler 23 turns counterclockwise along with a bevel gear 23d. Thus a planetary gear 24 engaging an outer gear 23b turns clockwise, and a guide disk 22 also turns clockwise to turn a shaft 21 clockwise. The torque around the rotary center of the disk 22 is applied to the shaft 21 in the form of a large torque obtained by multiplying the torque applied to the part 26c by the number of teeth of an operation handle and the idler 23 plus the number of teeth of the idler 23 and the disk 22. At the same time, the multiplied torque is applied also to a twist spring 25, and the degree of deformation is read by a pointer 23c of the idler and the scale 22d of the disk 22. thus the torque can be measured when the shaft 21 starts its rotation.

IPC: B42D9/04
Filed: 1982-04-15
Abstract: PURPOSE:To heighten sheet draw-out performance of a contact element used in a sheet handling device for turning over sheet materials or counting the number of sheets by disposing countless bar projections on the surface of the contact element to get high coefficient of friction. CONSTITUTION:A paper number deciding mechanism is adapted to judge whether paper 1 between contact elements 2, 3 is one sheet or plural sheets from whether the contact element 2 moves for the contact element 3 or not, when regulation force is applied in direction of an arrow 5 after the contact element 2 is pressed against the contact element 3 through paper 1 in direction of an arrow 4 with regulation force. In such a case, countless glass fibers 6 are buried in the surface of the contact elements 2, 3 in such a manner as to be oblique to the surface of paper 1. Since the forward end of the glass fiber 6 cuts into the surface of paper 1, the apparent coefficient of friction can be infinite as far as there is no breaking of the glass fiber 6 or no damage in the paper 1 surface. Therefore, the number of paper 1 can be judged stably and assuredly.

Abstract: PROBLEM TO BE SOLVED: To reduce the sheet resistance of an impurity diffusion layer by widening the width of the compound layer formed on the surface of the impurity diffusion layer even when the width of an element active region is the same. SOLUTION: After the surface of the SiO2 film 13 in an element isolation region gas been made lower than the upper surface of an Si substrate 11, a TiSi layer 19 is formed on the surface of an impurity diffusion layer 18 and a polycrystalline Si film 15. As a result, the surface of the TiSi2 layer 19 becomes lower toward the direction of the surface of the SiO2 film 13 on the boundary part with the SiO2 film, and the width of the TiSi2 layer 19 is wide even when the width of the element active region is the same. Accordingly, the sheet resistance of the impurity diffusion layer 18 is low, and current drive power and the like is high.

Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To lubricate a shaft sealing device in good performance by supplying a lubricating oil encapsulated in an oil sump formed in a roller housing to the internal circumferential space of the shaft sealing device. SOLUTION: A roller housing 1 is furnished penetratively with a first 12 and a second oil supplying hole 13 in such a way as directed from the outermost periphery of an oil sump 11 to the internal circumferential space 4a of a shaft sealing device, wherein the holes are inclined so that the rotational locus of the open end parts 122 and 132 on the space side has a smaller diameter than the rotational locus of the open end parts 121 and 131 on the oil sump side.

Title: Method for testing corrosion of muffler material
Inventor: NISHIJIMA TSUYOSHI
IPC: G01N17/00
Filed: 1987-03-16
Abstract: PURPOSE:To permit conduction of an adequate test in a short period by making the test by the sulfuric acid acidity obtd. by heating and boiling of an aq. ammonium sulfate soln. CONSTITUTION:The ammonium sulfate is thermally decomposed when an ammonium sulfate soln. in a corrosive liquid tank 1 is heated by a heater 4 after a test piece 5 is immersed in this aq. soln. Sulfuric acid and gaseous ammonia are then formed and steam is simultaneously generated as well. The gaseous ammonia and steam evaporate upward and rise through a siphon device 2 to a cooler 3. The sulfuric acid remains in the aq. soln. and the aq. soln. tends to the sulfuric acid acidity. This sulfuric acid acidity acts on the test piece 5 to corrode the same, by which the aluminum sulfate and iron sulfate are further hydrolyzed to form sulfuric acid and the sulfuric acid acidity of the aq. soln. is intensified. The corrosive environment is thus reproduced in the liquid tank 1. The progression of the corrosion of the test piece 5 is, therefore, accelerated and the time for the test is shortened.

CONSTITUTION: In such a state that a guide cover 13 is allowed to retreat to be separated from a press mold apparatus, a rubber product such as an O-ring is vulcanized and molded under heating and pressure by molds 1, 2. Next, a ram 5 and a vacuum hood 7 are raised to open the molds 1, 2 and the guide cover 13 is advanced from the rear to be allowed to approach the molds 1, 2 to surround the rear and right and left side parts of the molds 1, 2 and a release tool 15 is sent to the gap between both molds 1, 2 as shown by an arrow C by a reciprocal drive means 24. Molded products S are let fly rearwardly from the molding surfaces 1a, 2a of the molds by an air blow means 22 or a rotary brush 23.  The release tool 15 moves rearward gradually to separate the molded products S from the entire surfaces of the molding surfaces 1a, 2a of the molds to fly them rearward but the guide cover 13 allows the molded products to fall to a lower receiving container 16 to house them in the container.

Filed: 1978-05-26
Abstract: PURPOSE: For preventing the failure of rotors and a casing, to sotp a compressor when said rotors happen to reverse upon the starting of said compressor by stopping the power supply of a motor when suction port side pressure has become higher than discharge side pressure.  
     CONSTITUTION: When the rotors of a closed screw compressor 1 reverse, the pressure in a suction pipe 7 becomes higher than that in a discharge pipe 8. When suction pressure has become higher by the value corresponding to the difference of rigidity between the springs 11 and 12 of a reverse preventing device 15 than discharge pressure, a piston 13 moves, contacts 14 and 16 separate from each other, the power supply of a motor is stopped, and a compressor stops. Next, when a power supply switch is turned off for ordinary stoppage, the high pressure refrigerant gas present between a check valve 19 and said rotors is returned onto suction side through an auxiliary discharge pipe 10, a refrigerant passage 20, a solenoid valve 21 and an auxiliary suction pipe 9. Therefore, no refrigerant gas returns onto suction side through the clearance between said rotors. Thus, the reverse of said rotors can be prevented.
