Title: Energy storing device for on-load tap changer
Inventor: FUKUTOME TSUTOMU
IPC: H01F29/04
Filed: 1985-06-27
Abstract: PURPOSE:To reduce loss generated in a sliding section by supplying the sliding section with an eccentric plate, disposing the fixing points of a driving shaft fastened to the eccentric plate along the line of the direction of sliding and forming an energy storing device so as to have the relationship of work in a both-end support system sliding section. CONSTITUTION:When a sliding section 15 is pushed through an eccentric plate 12 fixed to a driving shaft 11 by driving force from a driving mechanism and displaced gradually in the A direction, an energy storing case 23 is fastened by a stopper at that time. An energy storing spring 20 consisting of a compression spring is compressed in the state, and the quantity of compression of the energy storing spring 20 slowly increases. When the quantity of compression of the energy storing spring 20 reaches a maximum position, a catch is tripped by a tripping pawl 17 and the energy storing spring 20 is released, and the energy storing case 23 is displaced instantaneously in the A direction. A changeover crank 29 connected to the lower side of the energy storing case 23 is turned at that time, thus completing the operation of release of energy storing on the starting of the driving of a diverter switch.

Title: Digger for bottom of sea
Inventor: SUGIHARA HIROSHI
IPC: E02F5/10
Filed: 1981-09-03
Abstract: PURPOSE:To enable the bottom of the sea to be smoothly excavated in a recess, by a method wherein an excavating part provided with jet nozzle and an excavated earth and sand draining device are mounted to a forward end of a base, and chain flat plates, which turn as it contacts a wall surface of an excavated ditch, are installed to both sides of the base. CONSTITUTION:With a high-pressure pump 4 actuated by means of an operational signal from a ship from a ship, a base B is moved forward by the operation of an endless track as sea water, drained from the high-pressure pump 4, is jetted to a ground at the bottom of the sea through jet nozzles 3. A ground, crashed by jet water current, is sucked as excavated soil through a suction inlet 6 by a sand pump 9 together with sea water, and is discharged to the outside of the base B through an earth drain pipe 11. In case an excavating depth is changed, the elevation of the front of the base B is adjusted by changing the jet angle of the nozzles 3 by means of a regulating cylinder 21.

Title: Killer circuit
Inventor: YAMAMOTO AKIHIRO
IPC: H03F3/72
Filed: 1982-08-12
Abstract: PURPOSE:To avoid a DC voltage at an output from being changed and to extend a dynamic range, by short-circuiting the collector and emitter of transistors (TR) constituting a differential pair so as to cut off the output. CONSTITUTION:When a voltage impressed to a terminal 2 is lower than a base potential of the TRs 7, 8, a signal inputted to a terminal 1 is amplified and outputted from a terminal 3. When the voltage impressed to the terminal 2 is higher than the base potential of the TRs 7, 8, the TRs 7, 8 are turned off. In this case, TRs 5a, 6a are turned on. Then, the signal inputted to the terminal 1 is not outputted from the terminal 3. Since a current having an amplitude equal to the collector current of the TR8 flows to the TR5a even in case when the killer operation is applied in this way, the DC potential at the terminal 3 is unchanged.

Abstract: PURPOSE:To achieve a better sealability without disturbing the pressure seal interface by performing a sealing work after substantially smoothing the irregularities caused by the groove in the internal circumferential wall at an open end of a metal pipe. CONSTITUTION:A mandrel 2 made of a material higher in hardness than a heat pipe 1 is inserted into a hollow member at an open end 12 of the head pipe 1. Then, for example, an open end member 12 undergoes a swaging being reduced in diameter with the application of a mechanical pressure from the outer circumference by a rotary swaging machine or the like. In this swaging work, a groove 11 carved in a circumferential wall 10 of the open end 12 is squeezed with the existence of the mandrel 2 so that the inner circumferential surface 10 of the open end 12 is made almost smooth. After the end of the swaging work, the mandrel 2 is pulled out and after the inside of the heat pipe 1 is cleaned up by a detergent to be evacuated, a working liquid such as pure water is injected thereinto. The open end 12 finer in diameter is cold pressure welded using a pressure welding machine 3 and the pipe is cut at a pressure welded part 13 on the final end side of the heat pipe 1. Using a welder 4, a weld part 40 is formed on a cut end face 14 to seal up the heat pipe 1 completely.

Title: Recording medium disk driver
Inventor: NODA TAIJI
IPC: G11B17/03
Filed: 1983-07-29
Abstract: PURPOSE:To secure the assured insertion of a disk by limiting the shift of a clamper in the early stage of turn of an operation knob. CONSTITUTION:The sloping surface 22a of an operation knob 17 is not set at the front of an opening 21 for the full period of turn of the knob 17 but set at the front of the opening 21 only in an early stage of the turn of the knob 17. This state relates to the insertion of a disk cartridge 1. While a cam 23 is provided into a interlocking mechanism and functions in the early stage to inhibit the shift of a clamper 8 toward a hub 5. Therefore the clamer 8 does not close to the hub 5 during the inserting period of the cartridge 1 based on the surface 22a. Thus the clamper 8 never prevents the insertion of the cartridge 1 or a disk 2. In such a way, problems such that the disk 2 is positioned inaccurately between the hub 5 and the clamper 8 and that a part 2a near the center of the disk 2 is damaged by a projected part 9 of the clamper 8 are decreased.

Abstract: PROBLEM TO BE SOLVED: To provide a fume-testing device for obtaining a reliable test result. SOLUTION: An electric wire W is supported while it is extended in a horizontal direction in an airtight testing bath 2. While a specific overcurrent is allowed to flow to the electric wire W, laser beams L are applied in the longitudinal direction of the electric wire W at the upper position of the electric wire W, and the scattered light of the laser beams L is monitored by a photosensor 22 such as a photomultiplier.

Abstract: PURPOSE:To obtain a printer having a high resolving power through which blurring of ink or deformation of paper would not occur, by assigning the density equal to the density range common to complementary color signals of the same dot to the density of a balck signal of the same dot. CONSTITUTION:When the density signals resulted from the complementry color conversion from a manuscript reading system are Y=6, M=3 and C=9, the amounts of color inks calculated by a circuit system to a multiplexer, and the common amount of the inks is substituted from the amounts of the complementary color inks to determine the difference of the amounts of the complementary color ink. As a result, with respect to, for example, a pattern including 4X4 tiny dots constituting one picture element, the amounts of color inks of Y=3, M=0, C=6 and BK=3 are obtained to be stored in memories. Further, when the amounts of inks of complementary colors Y, M, C and amount of black ink are successively arranged and recorded on corresponding positions on the 4X4 dot pattern by a register, the color inks would not be superimposed on the tiny dots of the 4X4 tiny dot pattern constituting the same picture element.
