Title: High frequency heating device
Inventor: BETSUSOU DAISUKE
IPC: H05B6/66
Filed: 1990-04-26
Abstract: PURPOSE:To cool an inverter circuit and a magnetron, and prevent erroneous operation of a control circuit by providing on a conductive casing a conductive material guide for guiding air form a cooling fan and a partition plate for partitioning the interior of the casing. CONSTITUTION:Air generated by a cross-flow fan 3 is directed through a guide 5 so as to cool an inverter circuit 1 and a magnetron 2. The guide 5 is formed with a conductive material such as a metal plate or a plate such as stainless including metal fibers, which divides the inside of a casing 4 to a plurality of spaces. The guide 5 serves as a partition plate for defining a guide for directing air and the inside of the casing 4 and forming a space not affected by leakage microwaves. A control circuit 6 for controlling a semiconductor switching element of the inverter circuit 1 and a filter circuit 9 are provided in a space located below the guide and not affected by the leakage microwave, for eliminating erroneous operation and leakage microwaves transmitted to a commercial power line external to the casing.

Title: Finishing controller for electrospark machining
Inventor: FUTAMURA SHOJI
IPC: B23H7/30
Filed: 1988-05-11
Abstract: PURPOSE:To improve accuracy on working by commanding an electrode to move over a predetermined finishing surface and stopping discharge when the number of effective discharge pulses reaches a predetermined value so that the electrode is moved away from a workpiece. CONSTITUTION:When a commanding unit 1 sends the command of power application to a working power source 3, the power supply is applied to a discharge gap between an electrode and a workpiece, while the number of effective discharge pulses is detected to send the detecting signal to a counter 4. A comparator 6 compares the number in the counter 4 with a reference value set to a set counter 5. When the former reaches the latter, the comparator 6 sends the signal to the commanding unit 1 to stop the finishing working in respect. That is, the command is sent to a table drive unit 2 to withdraw the electrode to the initial position. Thus, even if the desired movement position of the electrode is set to a remote one, the electrode is returned to the initial position when said number of pulses reaches a predetermined value, so that too deep cutting cannot take place.

Title: Coefficient setting circuit
Inventor: HORI MASATOMO
IPC: H03H15/00
Filed: 1988-05-11
Abstract: PURPOSE:To make a tap coefficient converge to an optimum value through a high speed operation by controlling the operation of an up/down counter. CONSTITUTION:The HOLD output of a quantizing means 41 is inputted to the HOLD inputs of the up/down counters 13, 14, 15, and the U/D output of it is inputted to the U/D inputs of the up/down counters 13, 14, 15 through a code inverter 43 as both being delayed by 0, T, 2T respectively by delaying units 44. The code inverters 43 multiply the U/D outputs of the quantizing means 41 by the output code of a code extractor 42, and supply them to the up/down counters 13, 14,15. The output of the code extractor 42 is the code of a difference between the respective output level of an output signal series and a reference output level, and the up/down conters 13, 14, 15 are turned into counting operation only when the HOLD input is '0', and they up-count when the U/D input is '1', and down-count when the U/D input is '0'. Thus, the high speed operation of the coefficient setting comes possible.

Title: Speed control method and device
Inventor: RINKAN ESU FUERISU
IPC: G01C19/70
Filed: 1989-05-06
Abstract: PURPOSE: To suppress the deterioration of feedback signals by vibrating a mobile element, so that the vibration can be used for pick-off signals for closing a feedback loop or oscillation loop, by subtracting the actual current in a torquer conversion element from the current of an immobile member. CONSTITUTION: The output voltage VD of a torque amplifier 14 is sent to the area surrounded by the dotted line, namely, to piezoelectric elements and a spring suspended mechanism. All of the piezoelectric elements are connected in parallel with each other. Elements CX1 , KQ, and Kp Q'd are the equivalent circuits of the piezoelectric elements which are connected in parallel when the elements are connected to a oscillatory suspended system. Namely, an electric current is supplied to the input of the amplifier 16, and the amplifier 16 converts the current into a voltage Vp to be supplied to a β-circuit 18 as a current-voltage amplifier. An AGC 18a and a multiplier circuit 18b generate a feedback signal VF to the amplifier 14 based on the voltage Vp and form a close feedback loop.  The amplifier 14 generates a voltage VD based on the signal VF and the voltage VD generates a current i1 by oscillating the piezoelectric elements.
