Title: Original point correcting system for mobile object
Inventor: TADA KIYOYUKI
IPC: G05D3/12
Filed: 1979-01-25
Abstract: PURPOSE: To secure the correction for the position shift of the device in a simple operation by obtaining the coincidence between the mark of the mechanical original point of the mobile object and the mark position on the monitor screen which corresponds to the original point of the mobile object programmed at the action control part.  
     CONSTITUTION: In the automatic wire bonder, 1st mark P is given on the monitor TV screen on which the semiconductor chip image is projected. The mark P is set in the form of the original coordinates of the capillary and in correspondence to the position information which is programmed previously at the control part, and then displayed at the position fixed on the monitor screen. Then 2nd mark Q is given onto the semiconductor chip screen opposing to the monitor screen and in the state under which the capillary is set to the mechanical original point position, and then projected onto the TV monitor screen via the ITV camera, After this, the position of the ITV camera is adjusted so that the coincidence may be obtained between marks Q and P. Thus the video information projected through the camera has no error to the program information. And accordingly, the shift distance and direction which are calculated can be decided as the shift amount and direction of the capillary.

Title: X-ray controller
Inventor: OOE MITSUO
IPC: H05G1/34
Filed: 1981-01-23
Abstract: PURPOSE:To permit continuous setting of bulb current value by feeding an adjusting voltage obtained by a bulb current setting means into a filament current caluclating means and a space charge correcting means and applying the difference of outputs into the filament of an X-ray tube. CONSTITUTION:The voltage DELTAV which varies in triangular wave form is obtained by transmitting the signal S1 of a bulb current selecting switch 10 into an adjusting voltage generating circuit 11. The filament current at a standard bulb voltage is calculated by setting S1 and DELTAV into a filament current calculating circuit 12, and the space charge correcting value is obtained by setting S1, DELTAV, standard bulb voltage, and set bulb voltage into a space charge correcting circuit 13. The difference of the both outputs is obtained from a differential amplifier 14, and thus the filament heating current for an X-ray tube 9 is formed. Accordingly, the adjusting voltage can be calculated automatically only by setting a desired bulb current value, and a switching signal can be formed, and the bulb current can be varied continuously and easily.

Title: Electronic timepiece
Inventor: HOSOYA KATSUMI
IPC: G04G5/00
Filed: 1990-01-17
Abstract: PURPOSE:To obtain the inexpensive electronic timepiece with high accuracy by calculating the time deviation of the electronic timepiece and thinning out or adding counting operation for reference oscillation pulses so that the time deviation becomes zero in a specific time interval. CONSTITUTION:For example, a display time 13:00:05 on a display device 102 is corrected into 13:00:00. A 1st storage means 104 is stored with 13:00:05; and 13:00:00 is stored in an area R1 of a 2nd storage means 106 and 12:00:00 is stored in a 2nd area R2. An observation period is therefore one hour and a time quantity which needs to be corrected is -5 seconds. Namely, the current time in the observation period is 5 seconds fast, so a frequency error is calculated from 5/3,600. For the purpose, a pulse control means 110 corrects the time deviation by thinning out the reference oscillation pulses so that the frequency error becomes equivalently 0.

Title: Tuning method for voice synthesizer
Inventor: ISHIDA KIYOSHI
IPC: G10L13/08
Filed: 1990-01-17
Abstract: PURPOSE:To prevent the deterioration in sound quality by increasing the attenuation degree of response energy in the several computation period sections at the last or top of sound source data with respect to the sound source data input having pitch periods, thereby decreasing the response waveform distortions in the fluctuation of the pitch periods. CONSTITUTION:A sound source input is given at the intervals of the pitch period and a filter circuit approximates the human voice tube to the cascade connection of sound tubes having plural sectional areas. A coefft. device K is given as the coefft. of the change in the sectional area with time by each element of the respective sound tubes by a sectional area coefft. computing section S. An attenuator ATT is provided in a delay circuit D to execute the attenuation processing of the energy to the backward progressing waves. This attenuation parameter is so applied as to sufficiently attenuate the backward progressive waves only in the several computation period sections at the time when sound sources change over. The mutual influence by the phase deviation between the response of the sound source after the pitch changeover and the response of the sound source one pitch before is lessened and the distortions of the response waveforms are decreased, by which the deterioration in the sound quality is prevented.

Title: Engine room cooling device
Inventor: NAKAJIMA KAZUSHI
IPC: F01P5/06
Filed: 1995-01-23
Abstract: PURPOSE: To improve startability at high temperature restart time and stability of idle rotation without actuating a radiator fan when an engine is stopped. CONSTITUTION: A control circuit 20 judges that an engine is restarted at high temperature when a cooling water temperature detected by a water temperature sensor 17 is not less than a prescribed value and an intake air temperature detected by an intake air temperature sensor 13 is not less than a prescribed value, and reduces a cooling water temperature preset value to actuate a radiator fan 19 more than an ordinary preset value. Therefore, at high temperature restart time, the radiator fan 19 can be actuated even in a temperature area where the radiator fan 19 is not actuated so far. A fuel temperature in a delivery pipe 22 is lowered by its air blowing effect, and influence of vapor is eliminated in its early stages.  Afterwards, when car speed becomes a prescribed value or more by considering a cooling effect by a traveling wind, or when a condition where the car speed is not less than the prescribed value passes by a prescribed time or more, the cooling water temperature preset value is restored to the ordinary preset value.

Abstract: PURPOSE:To cast a molten material always at an adequate temp. and good timing and to prevent the generation of foam, rough surface, etc., by forming a hermetic film of a combustible material and burning the hermetic film by the heat of a molten metal in the stage of pouring thereby rupturing the film. CONSTITUTION:A crucible 13 is imposed on a bottom wall 11 in a melting chamber 1a and a casting mold 14 is disposed on the lower side of the upper wall 11 in a casting chamber 2. The mold is held in hermetic contact with the hermetic film 15. The molten metal 35a in the crucible 13 is maintained in an adequate temp. range and in this state the whole part thereof passes through a molten metal passage hole 19 then through a casting hole 12 to burn and rupture instantaneously the hermetic film 15 by the heat of the molten metal 35a. The molten metal is thus cast through a sprue 22 into a molding cavity 23. The casting speed of the molten metal 35a is increased by the pressurizing force of the melting chamber 1a and the negative pressure generated in the casting chamber 2 by the rupture of the film 15. The molten metal is thus cast at an adequate speed into the molding cavity 23.

Title: General purpose brushless dc fan
Inventor: FURETSUDO EI BURAUN
IPC: H02H7/085
Filed: 1987-01-20
Abstract: A brushless DC fan (10) with a winding supply circuit (49) having an internal voltage regulator (53) can afford current limiting and thermal protection and provide various desired fan speeds without alteration of the basic fan circuit, the windings, or other manufacturing items. A voltage setting circuit element (63) can set fan speed externally and can be used to establish various fan speeds. An internal voltage establishing circuit element (58) sets the maximum speed. The regulator replaces the fan's protective thermistor to shut down the voltage to the windings (47) when locked rotor occurs. Bringing out a lead (21) for the purpose of connecting a speed controlling resistor, thermistor, or active programming means to the internal circuitry enables the fan's end user to alter operation as needed.
