Title: Electric discharge machine
Inventor: INOUE KIYOSHI
IPC: B23H1/08
Filed: 1984-10-08
Abstract: PURPOSE:To promote the discharge machining speed by adding specific % of additive composed of alloy of rear earth metal such as Co, La, Sc, Y and Ti, Al, Zr then making the adding amount controllable and controlling gas to be produced in working liquid. CONSTITUTION:Additive 14 composed of alloy powder of 72% La and 28% Al is placed in a hopper 13 then fed out through rotation of a screw 11 where the rotation is controlled such that it is added by 5-10% into the working liquid in a tube 7 to be fed from working liquid feeding unit 6. The working liquid mixed with additive 14 is fed between an electrode 2 and a work 1 and upon pulse discharge through pulse power source 5, the majority of the discharge energy is converted into heat to exhibit high temperature thus to fuse the discharging point of work 1 thereby the additive 14 will react with the hot water to produce gas mainly composed of hydrogen gas. Consequently, the insulation at the machining gap is improved to prevent the applied voltage pulse from causing arc discharge thus to promote effective discharge and to prevent excessive cooling due to the working liquid through thermal insulation effect of gas resulting in improvement of machining speed.

Inventor: KAIRIN MASATAKA
IPC: H04B1/40
Filed: 1983-11-11
Abstract: PURPOSE:To reduce the leading time of an output signal at application of power even with a coupled capacitor to an output terminal by inserting the 1st analog switch to a path receiving a power supply voltage and the 2nd analog switch in the path leading an output signal to a signal output terminal and also providing a voltage dividing circuit in a switched capacitor circuit used for a filter of a mobile radio communication device or the like. CONSTITUTION:A power supply input terminal 81 to an integration device 101 consisting of a switched capacitor circuit is connected to a single power supply 103 via the 1st analog switch 102 and an output terminal 9 is connected to an output terminal 106 via the 2nd analog switch 107. The ON/OFF control of the 1st and 2nd switches 102, 107 is conducted by a power-down control signal applied to a control signal input terminal 108. When a power-on signal is fed to a terminal 108, the switches 102, 107 are conducted and a signal is given to a load 2. In this case, since the potential of the signal output terminal 106 is kept always to a neutral potential, the leading time of the output signal at the transition from power-down to power-on is very short.

IPC: G01F23/56
Filed: 1994-08-11
Abstract: PURPOSE:To prevent a wire from coming off from a pulley because of slackening. CONSTITUTION:This apparatus is provided with a winding drum 4 to wind a wire having a weight 2 at the tip thereof, a delivery value measuring means 6 for a wire to be delivered from the winding drum 4 and a weight-change measuring device 7 to measure a reduction in the weight by lowering the weight 2 until it reaches a measuring surface. In this constitution, the wire is paid out, the weight 2 reaches the measuring liquid surface, and changes in weight thereof is detected to measure the paid-out length of the wire. Moreover, the winding drum 4 is screwed down on a thread shaft and the rotation thereof in the paying-off or winding of the wire shifts axially synchronizing with winding pitch of the wire so that the position of paying-out or winding the wire is always the same facing a guide pulley 5 as opposed to the winding drum 4. Thus, any slight slackening of the wire will not cause the wire to come off from the guide pulley while winding of the wire on the winding drum is accomplished accurately.

Abstract: PURPOSE:To obtain a flattening agent which can be cured by heating to form a highly flattened cured film excellent in flatness, hardness, heat resistance, chemical resistance, etc., by combining a specified organic high-molecular compound with an epoxy curing agent. CONSTITUTION:A flattening agent is obtained by mixing an organic high- molecular compound (A) comprising structural units of the formula and having a weight-average molecular weight of 500-15000 with an epoxy curing agent (B) (e.g. phthalic anhydride, tetrahydrophthalic anhydride or m-xylenediamine). Examples of compound A include a homopolymer entirely consisting of the structural units of the formula and a copolymer consisting of the structural units of the formula and structural units derived from another polymerizable monomer (styrene is desirable from the viewpoint of a capability of thermal flattening). This agent has a low melt viscosity in a solventless state, can easily be cured by heating, and excels in properties such as hardness, heat resistance and chemical resistance, so that it is useful not only as a flattening agent but also as a molding material, a sealing material or an adhesive material.
