Title: Reset control device for equipment
Inventor: MARUHASHI HIROO
IPC: G05B9/02
Filed: 1987-03-11
Abstract: PURPOSE:To prevent the resetting actions of an equipment due to noises, etc., by writing the prescribed contents into a memory when a valid state of the reset signal is released and the power supply voltage drops and controlling the resetting actions based on the memory contents. CONSTITUTION:The initialization of a printer is carried out when the power supply voltage exceeds a reference level after a power supply is turned on. At the same time, a working mode is written into a nonvolatile memory of a microcomputer unit 4. Then, a reset signal is valid when a noise is produced in a picture recording state. However, it is checked and known that the nonvolatile memory of the unit 4 is working with the rise of the reset signal. Thus a printing action is carried out as it is. When a main switch is turned off, the power supply voltage drops less than the reference level and an interruption signal INT is produced. Then a microcomputer unit 3 writes a stop mode into the nonvolatile memory of the unit 4. The reset signal is stopped when the power supply voltage drops further and the power supply voltage is set at zero.

IPC: B24B19/08
Filed: 1987-03-11
Abstract: PURPOSE:To aim at reduction in polishing time and improvement is accuracy of a finished surface, by setting up an abrasive polisher so as to become perpendicular to a working surface at all times, and moving it for polishing as tracing the specified curved surface form while describing a screw motion path. CONSTITUTION:A workpiece 7 with a curved surface is rotated at low speed in an (e) direction. An abrasive polisher 8 is always kept so as to become perpendicular to the curved form, and it is rotated in a (g) direction by rotation of the workpiece. In addition, an abrasive shaft housing 12 is moved in a radial direction (f) of the workpiece 7 so as to trace the specified curved form while rotating in a (h) direction around a turning shaft, thus polishing takes place. At this time, a moving path of the abrasive polisher 8 is described as a spiral path by a distance A between an axis of the polisher 8 and a housing center line. Size of this spiral path is varied by varying this distance A. With this constitution, stock removal grows larger and polishing time is shortened whereby the workpiece is uniformly machined so that accuracy in a finished surface is improvable.

Filed: 1982-04-07
Abstract: PURPOSE:To keep the mean DC voltage of a reference waveform part at a fixed level without giving any effect to the reference waveform part, by sampling the DC voltage of the reference waveform part and forming a feedback loop which sets the mean output voltage at a fixed level. CONSTITUTION:The video signal supplied from a terminal IN passes through a video amplifier VA and is clamped by a clamping circuit consisting of an analog switch SW, a capacitor C and a choke coil L and with the control signal given from a terminal C1IN. The clamping voltage samples the video signal passed through a buffer amplifier BA through a sample holding circuit SH and with the control signal given from a terminal C2IN and then averages it through an LPF. The output of the LPF is compared with the reference voltage of a clamping voltage generating circuit VCL through an error amplifier AMP and then fed back to the amplifier BA via the analog switch SW. As a result, the DC level can be stabilized with no effect of level variations of the input signal.

Abstract: PROBLEM TO BE SOLVED: To cancel or attenuate the reaction force of a vibration plate by using one loudspeaker unit, piercing plural through-holes in a damper and putting in/out air in the lower part of the damper and a cap. SOLUTION: Two or three thin cloths are superimposed and bonded so as to form the damper 17 or a synthetic resin solution, etc., is coated on the surface of the damper in order to obtain the highly airtight damper and the plural thin through-holes 21 are pierced at proscribed positions. Air flows into two space parts 20a and 20b formed at the rear side of the damper 17 by the vibration of the vibration plate 10, and pressure in the volumes of the parts 20a and 20b is fluctuated. When the number of the holes 21 is set to n, an action force FD/n and reaction force -FD/n with respect to it are generated by the flow-in air in the holes 21 of the damper 17. Therefore, balancing is executed to obtain FD/n+FD/n+...=F1 so that a reaction force -F1 and a reaction force -(FD/n+FD/n+ and so on) are cancelled.

Abstract: PURPOSE: To obtain a wide range of measurement without being restricted by the fluidity of the fluid to be measured by combining the heating metal wire for detecing Kalman's vortex with a function of a hot-wire current meter.  
     CONSTITUTION: Heating metal wires 5 and 5' serving as a hot-wire current meter are provided behind a vortex generator 4 provided in the suction tube leading to the engine. The output of the metal wires 5 and 5' is inputted into the hot-wire circuit section 9 in such a manner that the electric signal VDC is outputted from the output terminal A corresponding to the hot-wire current meter while the AC signal VAC is outputted from the out terminal B corresponding to the Kalman's vortex current meter. When the suction tube 2 is under a fixed vacuum, that is, the sucking pulsation is large, the switch 11 is activated to halt the action of the 12. The output V 1  of the hot wire current meter is produced by the signal selection circuit 14. When the sucking pulsation is small, the switch 11 fails to work. Thus, the calibration device 12 calibrates the output V 1  of the hot-wire current meter while the output V 2  of the Kalman's vortex current meter is produced from the signal selection circuit 14.
