Title: Manufacture of disc for rotary encoder
Inventor: KATONO TAKASHI
IPC: G01D5/36
Filed: 1984-12-26
Abstract: PURPOSE:To obtain an inexpensive disc for an optical encoder showing almost no warpage, by applying heat treatment to a disc formed by electroplating under pressure in a state grasped by a jig. CONSTITUTION:Resist 8 is formed to a thin metal plate 7 at a part other than a disc pattern. This thin metal plate is used as a cathode and a metal 9 is precipitated by electroplating to form a disc. Subsequently, the removal of the thin metal plate 7 and the release of the resist 8 are performed. By this method, the part, where the resist 8 was present, comes to a slit part 10. The disc obtained by this process generates warpage (b) by internal strain at the time of plating. Hereupon, the metal disc having warpage is grasped by the jig 11 and subjected to heat treatment under pressure to correct warpage. According to this manufacturing process, the highly accurate and highly reliable disc for an optical rotary encoder excellent in flatness and having slits in high density arrangement is obtained by using an inexpensive metal as a base material.

Title: Tightening and disassembling of bolt and nut
Inventor: SAKAMOTO HIROSHI
IPC: F16B31/04
Filed: 1991-10-22
Abstract: PURPOSE:To improve workability and safety by tightening or loosening a bolt and a nut by way of applying tensile stress on the bolt by hydraulic pressure and then lessening wear of a screw by cancelling the tensile stress at the time of tightening or disassembling the large caliber bolt and the nut. CONSTITUTION:After a nut 2 is turned until it adheres closely to the upper surface of a flange 7, a bolt drawer 3 is screwed in the upper end of a bolt 1, and hydraulic pressure is introduced to the inside of the bolt drawer 3 by a hydraulic pump 5. Hydraulic pressure 8 pushes a piston 4 downward and pushes up the bolt drawer upward, the bolt 1 is pulled upward, and a gap is produced between the lower surface of the nut 2 and the upper surface of the flange 7. In this state, the nut 2 can be turned by small torque. When the nut 2 is screwed in by a required amount and hydraulic pressure is eliminated, the bolt 1 returns to its original length, and it is possible to tighten the flange 7 by a tightening force equivalent to the amount with which the nut 2 is screwed in the state where the bolt is extended. Consequently, it is possible to lessen wear of a thread ridge at the time of tightening and disassembling and to improve workability and to lower a danger.

Abstract: PURPOSE:To constantly control the amount of stroke of an idler for adjusting the tensile force of a caterpillar independently of the size of external force applied to the idler by providing a second cylinder with the smaller amount of stroke than that of a cylinder for adjusting the tensile force of the caterpillar in connection state. CONSTITUTION:When the external force pressing a rod 5 to an idler 6 that supports a caterpillar for a track-laying vehicle movably is applied, higher pressure than the pressure set by a deceleration valve 12 is generated in the head side chamber 7a of a first cylinder 2 and the respective chambers 20 and 22 on both sides of the sub piston 18 of a second cylinder 3. When the pressure reaches the preset pressure alphaof a second relief valve 24, the pressurized oil of the chamber 22 is exhausted to a tank 27 through the second relief valve 24 and such and the sub piston 18 is moved right against a screw 21. At the same time, the pressured oil of the chamber 7a is guided into the chamber 20 from a path 19 to the chamber 20 and a main piston 4 and the idler 6 is moved right. Besides, when excessively external force is applied suddenly to the idler 6, the main piston 4 and the idler 6 are moved right by the valve opening of the first relief valve 8.

Title: Rotary type magnetic head device
Inventor: MATSUSHITA MASAOTSU
IPC: G11B5/53
Filed: 1989-10-20
Abstract: PURPOSE:To obtain the uniform contact between a magnetic head and a magnetic tape by changing the projecting rate of the magnetic head by the rotating phase of an upper rotary drum when there is a difference in the floating quantity of the magnetic tape in the winding part of the magnetic tape to a rotary head device. CONSTITUTION:A slider 10 pressed to the outer periphery of a guide 8 is rotated and displaced along the outer periphery of the guide 8 when the upper rotary drum 4 rotates. The outer periphery of the guide 8 has a cam shape and, therefore, an auxiliary head base 12 is displaced in the normal direction of the upper rotary drum, by which the projecting rate of the magnetic head 5 is changed. The projecting rate of the magnetic head changes like a curve III from the point A where the winding starts up to the point B where the winding ends in this case so that the specified difference is maintained for the floating rate from the upper rotary drum. The magnetic tape and the magnetic head are brought into uniform contact with each other from the point where the winding of the magnetic tape starts up to the point where the winding ends even if the rotary drum is rotated at a high speed in such a manner.

By the operation permission signal, a relay 12 is operated, and an external combustion type heater 9 starts operation by the supply of electricity from the battery 8. When operation is not permitted, the relay 12 is not operated, and no electricity is supplied into the heater 9, which is not operated. Thus, the battery voltage is secured, and engine start is guaranteed.
