Title: Fan
Inventor: ARAKAWA YOSHIAKI
IPC: F04D27/00
Filed: 1982-06-29
Abstract: PURPOSE:To permit to control the amount of ventilation automatically in accordance with various heat transfer conditions by a method wherein a sensor, consisting of a thermal resistor and a temperature sensitive element, which are provided near a heater, is provided to control the amount of ventilation based on an information obtained from the temperature sensitive element. CONSTITUTION:When a temperature in the sensor 2 is increased gradually, a thermostat 23 is put ON and terminals 40, 41 are short-circuited. Consequently, the fan 1 begins weak airflow operation while the airflow, sent out of the fan, increases the convection heat transfer coefficients of a heating body, situated in the air path of the fan, and the sensor 2. Therefore, the temperature in the sensor 2 is decreased. At te same time, the temperature of the heating body is also decreased. Whereby, the thermostat 23 is put OFF, the fan 1 stops the ventilation and the temperature in the sensor 2 is increased again. The ventilation to the heating body may be controlled by the repetition of this cycle.

IPC: B41M1/42
Filed: 1988-05-09
Abstract: PURPOSE:To enable application of an ink in a larger thickness and enhance bond strength of the ink to an object to be printed, by connecting a DC power supply to a conductive material constituting the surface of a printing plate and a conductor layer of a support, and passing an electric current from the power supply to generate an electrostatic attractive force between the ink adhered to the plate surface and the conductor layer of the support. CONSTITUTION:In the case of intaglio printing of a figure, an object 3 to be printed is supported on the surface of a conductor layer 2a of a support 2, an appropriate amount of a conductive ink 4 is contained into recessed parts of an intaglio plate 1c of a printing plate 1 by a doctor blade 6, and a DC power supply 5 is turned ON to pass an electric current. The object 3 serves as a dielectric, and an electrostatic attractive force is generated between the ink 4 and the conductor layer 2a. The attractive force is added to a pressing force of the printing plate 1, whereby the ink 4 is strongly attracted and transferred onto the surface of the object 3. By operating a polarity change-over switch 25 provided in a power supply circuit, the electrostatic attractive force generated can be continuously augmented. By this, it is possible to apply the ink in a larger film thickness, as compared with that in the conventional method.

Title: Capacitance sensing type touch button circuit
Inventor: MATANO YOSHIO
IPC: H03K17/96
Filed: 1995-05-12
Abstract: PURPOSE: To obtain with simple constitution a capacity detection type touch- button circuit capable of preventing the generation of malfunctions due to humidity and dew condensation. CONSTITUTION: The phases of an input from an oscillation circuit 1 and an input phase-shifted by the impedance of a touch-button 6 are judged in an in- phase state and an OR result between both the inputs is converted into a pulse width by a phase shift/pulse width conversion circuit 3. The pulse width is converted into a level signal by an integrating circuit 4, and the level of the level signal is judged by a button operation judging circuit 5 to detect the on/off of the button 6. Since the phases are judged to be an in-phase state, the change direction of pulse width due to high humidity or dew condensation in the state of the button 6 not touched by a person is reversed from the change direction of pulse width in the touched state of the button 6, preventing the generation of malfunction due to high humidity or dew condensation.  Since the reference level of phase judgement is set up near the center of amplitude, the effects of an amplitude change, waveform distortion, etc., are removed and the generation of malfunctions is prevented.

Abstract: PURPOSE:To profitably solve the problems of reduction of life of a circular tool during partial trimming and of defective chip ejection by making the circumferential speed of the circular tool faster the speed of a steel strip at non- trimming time before touching the partial lugs of the steel strip by attaching a circular tool rotating motor of smaller capacity. CONSTITUTION:The side trimming is performed by a pull-cut method by which a shearing force required for trimming is generated by giving a pull at a steel strip, and a motor 6 may be of small capacity enough to rotate circular tools 3, 4 at a specified speed. In a case of partial trimming, a calculation control device 9 decides a non-trimming state from a ratio of the circumferential speed of the circular tool to the speed of the steel strip, turns a clutch 8 ON to start the motor 6. The control device makes the circumferential speed of the circular tools 3, 4 detected by a detector 10 1 to 15% faster than the speed of the steel strip 1 detected by a steel strip speed detector, the circumferential speed being desirable to be in a range of 30m/min. When the calculation control device 9 detects a load current and further detects a impact current, the clutch 8 is turned OFF.
