Patent JP-S6311220-A (JP)
Title: Electric discharge machine
Inventor: SAKAI AKIHIRO
IPC: B23H1/02
Filed: 1986-07-02
Abstract: PURPOSE:To prevent pulses from break to provide uniform roughens of worked surface by detecting the pulse break of working current to supply voltage to the primary side coil of a pulse transformer and instantly supply current between electrodes. CONSTITUTION:The working current value of a working power supply 13 is comapered with the set current value of a variable resistor 18 by a comparator 20 to generate outputs when voltage is not applied between electrodes of an electrode 1 and a workpiece 2 and when the pulse break occurs, and the outputs are integrated by a counter 21 on the basis of the cycle of an oscillator 23 to generate H output when a set pulse width value is reached. Thus, an exclusive OR gate 24 generates H output in the occurrence of pulse break to turn on a transistor 25 and overlap compensating currents by a pulse transformer 26 for compensating for the drop of working current and preventing the pulse break. Thus, the electrode is prevented from wear increase in the occurrence of pulse break and the uniform roughness of worked surface of a workpiece can be provided.

Title: Constant current circuit
Inventor: KANEZAKI KOICHI
IPC: H03F3/343
Filed: 1986-07-02
Abstract: PURPOSE:To evade the effect of the fluctuation of the power supply voltage after the start by supplying the start current to the 1st constant voltage element at an early stage of the start and then cutting off the start current flowing to said constant voltage element. CONSTITUTION:The start current flows to the 2nd constant voltage element 10 via a start resistance 9 in an early stage of the start. Thus the terminal voltage of the element 10 rises up and a switching transistor TR11 is biased forward. As a result, the start current is supplied to the 1st constant voltage element 1 via the base and the mitter of the TR11. However the TR11 is adversely biased and cut off when the terminal voltage of the element 1 rises up to the terminal voltage level of the element 10. Then the start current is not supplied to the element 1 any more. Thus the output current of an output terminal 7 is not affected by the fluctuation of the power supply voltage even if the power supply voltage supplied from a terminal 8 has fluctuation.

Title: Electrode with improved durable length of time
Inventor: KENESU ERU HAADEII
IPC: C23F1/26
Filed: 1993-06-25
Abstract: A metal surface is now described having enhanced adhesion of subsequently applied coatings combined with excellent coating service life. The substrate metal of the article, such as a valve metal as represented by titanium, is provided with a highly desirable rough surface characteristic for subsequent coating application. This can be achieved by various operations including etching and melt spray application of metal or ceramic oxide to ensure a roughened surface morphology. Usually in subsequent operations a barrier layer is provided on the surface of enhanced morphology. This may be achieved by operations including heating, as well as including thermal decomposition of a layer precursor. Subsequent coatings provide enhanced lifetime even in the most rugged commercial environments.

Title: Blow pin for blow molding
Inventor: YAMAMOTO KAZUYUKI
IPC: B29C49/66
Filed: 1988-06-23
Abstract: PURPOSE:To evenly cool the whole parison by a structure wherein a conical body is provided so as to be opposite to the jetting port at the tip of a blow pipe, which is inserted in the parison. CONSTITUTION:After a parison 4 is pinched by a cavity mold 2 and a core mold 3, air is forced through an influx port 2 in a cylinder main body 11, resulting in advancing a large piston 16 together with a blow pin 7 so as to thrust the parison 4 with a breaker 41 in order to insert the tip part of the blow pin 7 in the parison 4. When the large piston 16 reaches its forward limit, a circulating port 24 overlaps with the communicating port 26 of the large piston 16 so as to force fluid such as air or the like in the communicating port 26. The pressure of said fluid pushes the central part 32a of a small piston 32 so as to advance the small piston 32 with respect to the large piston 16 against the energizing force of a spring 33 and consequently also advance a cap 39 through a rod 38, resulting in opening the jetting port 37 of a blow pipe 35. In addition, the fluid flowing in the parison 4 through the jetting part 37 expands in a cavity 5 so as to make the parison 4 into the predetermined shape and at the same time to cool the parison 4.

Title: Method and apparatus for taking off form in stencil printing machine
Inventor: FUKAZAWA TOSHIO
IPC: B41L13/14
Filed: 1998-06-04
Abstract: PROBLEM TO BE SOLVED: To desirously take off a form without the necessity of complicate constitution comprising an exclusive power source, mechanical part, or the like by operating a form take-off means by making use of reverse rotation of a form cylinder in the opposite direction to that during printing so as to take off a base paper. SOLUTION: An oscillating arm 7 rotates in the counterclockwise against the urging force of a coil spring 17 by reverse rotation of a form cylinder 1 into the arrow direction (d) during taking-off of form. As such a planetary gear 11 moves to the side of a gear 21 to mesh therewith. As a result, a take-off roller 19 rotates in the direction of arrow (c). A base paper 5 wrapped around and secured onto the outer peripheral surface of the form cylinder 1 is in conditions where clamp done by clamping means is released during taking-off, and its rear end is raised from the form cylinder 1. In these conditions, by causing the form cylinder 1 to rotate in the reverse direction of the arrow (d), the rear end of the base paper 5 is raised by a base paper separation claw to thereby be taken off passing through between a taking-off form forwarding roller and the base paper separation claw.

Title: Intake air heater
Inventor: ITOU TOSHIHIKO
IPC: F02M31/135
Filed: 1979-11-30
Abstract: PURPOSE: To vaporize effectively the wall flow of fuel which is likely to appear when the fuel temperature is relatively low and thus reduce the ratio of the harmful components contained in the exhaust gas and improve the fuel consumption by providing an intake air heater by means of a mounting stay in an extension pipe projecting into an intake manifold from an intake pipe.  
     CONSTITUTION: At an engine start, when a battery voltage is applied to the heater 30, a current flows through a plus conductive wire 39, heating plate 38, PTC ceramic heater 41, cushion member 42, casing 31, stay 26, extension pipe 23 and intake manifold 12. Thus the heater 41 generates heat to warm the heating plate 38 quickly. On the other hand, when the engine temperature is low and hence the temperature of the inner wall of the intake pipe 10 is also low, the fuel supplied upstream of a throttle valve 15 is difficult to be vaporized. Therefore, a large amount of fuel is apt to flow in a wall stream along the inner wall of the intake pipe 10. When the wallstream drops from the lower and of the extension pipe 23, the fuel drops collide with the heating plate 38 to be vaporized quickly. Accordingly, the fuel thus vaporized completely is supplied to each cylinder of the engine.

Abstract: PURPOSE:To make it possible to eliminate a permanent magnet and to reduce a driving current during a printing time by providing a miniature amplitude operation valve on a spring charge type printing head. CONSTITUTION:A miniature amplitude operation valve 5, a guide 6, a movable iron core 7, a spring 8, a yoke 9 and a coil 10 are provided to a spring charge type printing head. The miniature amplitude operation valve 5 is depressed by the spring 8, and acting as a stopper of the spring 1, and an electric currentis not flowed in the coil 3 and the coil 10 under the condition in which an energy is accumulated in the spring 1. In a printing time, the printing action is carried by the energy accumulated in the spring 1.
