Abstract: PURPOSE:To shift a transmission from forward fifth gear speed to the fourth one inexpensively by merely removing each one piece of planetary gears and clamping elements. CONSTITUTION:This planetary gear type transmission is provided with each of first to third planetary gears 4 to 6 in order, and each of first to third clutches C1 to C3 and both first and second brakes B1 and B2 are all installed at the side of an input shaft 3 of the planetary gear 4, while a third brake b3 is set up in space between the two planetary gears 5 and 6, through which forward fifth gear speed and backward first gear speed are securable. When the clutch C1 and the brake B3 are clamped together, rotation of an input shaft is transmitted to a second sun gear 5s and a third sun gear 6s, whereby a third ring gear 6r is secured tight. With this constitution, the rotation decelerated by the planetary gear 6 is transmitted to an output shaft 7 connected to a third carrier 6c, and thereby the forward first gear speed is securable. Since this brake B3 and the planetary gear 6 will operate only in time of the forward first gear speed, if they are removed, it turn to a transmission of forward four speeds.

IPC: B21F33/00
Filed: 1992-03-09
Abstract: PURPOSE:To provide reaction receiving plates which are served for reducing the weight of a reinforcement chuck and improve the workability by reducing the working load. CONSTITUTION:A number of reinforcements 23 are successively inserted into reinforcement inserting grooves 16a, 16b of reaction receiving plates 12, 13, and a chuck nut 22 is brought close to the reaction receiving plate 12 on the left side by rotating a screw rod 21. The chuck nut 22 applies the force in the expanding direction to the respective reinforcements 23 and presses them against and fixes them to the arm part 17 of the reaction receiving plates 12, 13. The reaction receiving plates 12, 13 form a pair of arm parts 17 on the outer circumferential part of a disk body 14 by cutout-forming a pair of reinforcement inserting grooves 16 from an upper opening part of the disk body 14 in an arc shape. The arc 31 of the reinforcement inserting groove 16 is off-centered from the center 32 of the disk body 14 toward the opening side of the reinforcement inserting groove 16. Eccentricity of this arc center 31 allows securing of the maximum bending moment applying part 33 having a sufficient width to the root part of a pair of arm parts 17. This design allows the plate thickness of the reaction receiving plates 12, 13 to be smaller, leading to the lightweight structure.

Abstract: PURPOSE:To avoid adverse effect on a copied picture, by taking the number of vibrations generated at every pitch in case of a chain etc. to a high speed being a high number of vibrations which does not deteriorate an image MTF. CONSTITUTION:The number of teeth of a sprocket 13 fitted to a main motor 2 is three times of conventional systems. Since the speed of a chain 4, timing belts 8 and 11 is taken three times the conventional speeds, the number of revolutions of an original carrying belt driving shaft 1 is reduced to 1/3 by a gear. That is, the timing belt 11 drives a gear 15 (18 teeth) geared with a gear 14 (54 teeth) fitted to the said driving shaft 1 and a pulley 16 (19 teeth) fixed coaxially. Thus, the speed of the chain 4 and the timing belts 8 and 11 is taken three times the conventional speeds and the number of vibrations due to the chain and the timing belts can be increased.

Abstract: PURPOSE: To use a sailing device as a wind-driven generator when the equipment is at anchor and as a sailing device when the equipment is taken in tow by providing blades and sails on a rotary body.  
     CONSTITUTION: When the equipment is at anchor, a winding drum is rotated and the sails 20 are stored in a horizontal member 15. When the blades 19 receive wind presure, the rotary body 18 rotates and when a clutch 13 is connected, the rotation of the rotary body 18 is transmitted to an electromotor-generator 1 through bevel gears 9, 10 and a transmission 3. Therefore, generation is conducted and electric power is supplied to a batery. When the ship is taken in tow, the winding drum is turned back to spread the sail 20. When the power of the battery or the generator is supplied to the electromotor generator 1, the rotary body 18 rotates, the transmission 3 changes into a reduction gear and the rotary body 18 rotates at a low speed. Then, when the rotary body 18 is rotated up to a desired position to cut the electric power source in conformity to the wind direction, the rotary body 18 stops and an electromagnetic brake 4 works and therefore, the rotation of the rotary body 18 is braked and fixed at the desired position.

Title: Method for measuring temperature of tubular body
Inventor: INOUCHI TOORU
IPC: G01J5/52
Filed: 1982-03-30
Abstract: PURPOSE:To reduce the measuring error, by attaching a radiation source, which has a tube end shielding function, does not reflect energy, and can grasp the radiating energy, to the wall of a furnace, which faces the other end of the tubular body. CONSTITUTION:The wall part of the furnace faces the tube end 1b, which is located at the opposite side of the tube end 1a that is observed by a radiation meter 3. The wall part is made to be the radiation source 7, which does not reflect the energy owing to blackening treatment and the like. The amount of the member of the radiation source 7 is determined so that the radiated energy, which is inputted from the tube end 1b, is reflected in the inside of the tubular body 1 in the furnace, and supplied to the radiation meter 3, can be grasped. Therefore, the energy generated from the inner surface of the tubular body 1 can be obtained by subtracting the radiated energy, which is generated by the radiation source 7 and supplied to the radiation meter through the inside of the steel tube 1 from the total radiated energy received by the radiation meter 3. Thus the temperature of the steel tube can be found.
