Title: Electric discharge machining device
Inventor: TAKAHASHI TOSHIAKI
IPC: B23H1/02
Filed: 1987-07-02
Abstract: PURPOSE:To eliminate power losses by a current limiting resistor by providing a plurality of d.c. pulse power source circuits in a machining current supply section, and by applying supplying machining current between electrodes from the d.c. pulse power circuits having a predetermined time difference. CONSTITUTION:Working pulses from a machining pulse oscillator 10 turn on and off switches 6a, 6b through switch drive circuits 11a, 11b. For example, when the switch 6a is turned on, the voltage of a d.c. voltage source 5a is applied between an electrode 3 and a workpiece through an interpole current reverse checking diode 7a and a reactance 21a. When it is turned off, current runs through a diode 9a to a flywheel current absorbing voltage source 22a. When a similar trapezoidal shape current is fed by the switch 6b which is turned on with a predetermined delay, the current 1a becomes zero. Thus, it is possible to feed a trapezoidal current having a maximum current value maintained during a predetermined time, between the electrodes with no use of a current limiting resistor, thereby it is possible to enhance the energy efficiency.

Abstract: PURPOSE:To prepare a synthetic resin tube showing a three-dimensional appearance and a high-grade appearance and having irregular patterns by holding a transparent resin between different two-color opaque colored resins and successively arranging all of the resins in an annular stripe state to emit the same under rotation in a molten state. CONSTITUTION:The annular emitting part 1 of a die is divided into a large number of emitting orifices at an equal interval and different two-color opaque resins 2, 3 and a transparent resin 4 are successively arranged to those emitting orifices in an annular stripe state so as to hold the resin 4 between the opaque resins 2, 3. The resins 2, 3 are thermoplastic and supplied in a molten state to be extruded in a tubular form while the annular emitting part 1 is rotated. At this time, the resins 2, 3, 4 are extruded in the annular stripe state but, since the flow velocities of the resins are different between the contact part and non-contact part of the die at the time of rotation, positional shift is generated between the resins and a shape is collapsed to develop irregular patterns such as grain patterns. A molded product formed by the integral injection molding of a neck part 6 having an extraction port provided thereto by drilling and a shoulder part 7 is thermally welded to the upper end opening part of the formed tube 5 and the lower end opening part of the body part of the tube 5 is heat- sealed as shown by a numeral 8 to complete a tube container.

Title: Multiaction type electronic digital timer
Inventor: OKUYAMA KENJI
IPC: G04G15/00
Filed: 1980-11-27
Abstract: PURPOSE:To stabilize the starting of a timer-operated recorder by allowing the timer-on thererof at a given time before the preset time with a cue function attached. CONSTITUTION:Timer counters 60a and 60b for setting the timer-on time are initially set at 12:29:55, 0:0:0 or the like. Closing a cue switch turns the output Q of a JK type FF to a high level to open and close an AND gate and an And gate 62a and 62b. As soon as the contents of a clock counter 64 coincide with those of a counter 64a, the output of a comparator 66 is converted into a timer- on signal via the gate 62a so as to serve as a cue for activating the timer-on action at a given time such as 5sec before the preset time. This ensures stable starting of a recorder or the like requiring some time length before it is stabilized through a pre-starting by a timer.
