Filed: 1986-02-19
Abstract: PURPOSE:To satisfy both an output characteristic and contact start stop attraction characteristic by providing a piece of a groove which intersect at a specific angle with a circle concentrical with the center of a disk and is limited in width and depth onto an anodically oxidized film to the specific width in the region where the slider of a magnetic head moves.

Filed: 1981-03-09
Abstract: PURPOSE:To improve reception performance by increasing the S/N ratio of a car radio by connecting some part of an antenna serving as a heating conductor, where the amount of noise distribution is smallest, i.e. a one-side bus and one terminal of a feeder. CONSTITUTION:When the 1st receiving antenna (1st conductor 2) serving as a heating conductor is used as the heating conductor and is heated by being fed with a heating current from a positive-side bus 3' for defrosting a rear windshield 1, the heating current contains noise components passed through a noise filter 9. A negative-side bus 3 where the amount of the distribution of the noise components is smallest is connected to a feeder 8 through the 3rd conductor 7. Then, the noise components contained in the heating current inputted to a car radio which is not shown in the figure are least, and therefore the car radio is not affected by the noise components much. Thus, the S/N ratio of the car radio is increased and its reception performance is improved.

Title: Constant voltage controller
Inventor: ONODA YOSHIMITSU
IPC: H02M7/155
Filed: 1981-03-13
Abstract: PURPOSE:To control the output voltage of a thyristor circuit at a constant level without causing any transient state and regardless of a sudden change of power supply voltage, by controlling the gate of a thyristor converter with the output of a constant voltage magnetic amplifier. CONSTITUTION:With the combination of a thyristor circuit that rectifies AC current and a constant voltage magnetic amplifier 4 that controls the gate of the thyristor, the wave crest of the voltage in a main circuit decreases with the reduction of power suply voltage Ea. On the other hand, the firing angle thetam increases according to the decrease of Ea by the function of the constant voltage for the output of the amplifier 4 which uses the voltage Ea as a power supply. As a result, the flowing angle thetaT of the thyristor also increases to keep the mean value of the output Ed of the thyristor circuit at a constant level regardless of the reduction of the Ea. Furthermore, no transient state occurs at the output side of the thyristor circuit which is controlled by the amplifier 4 although the power supply voltage has a sudden change.

Abstract: PURPOSE: To fully automatically manufacture a coiled electric wire, by providing a bonding liquid  coating traverser, an electric wire protruding pipe and a coil making unit which comprises a lead  winding model, a winding model holder, a stripper pin, etc.   
     CONSTITUTION: When manufacturing is started, an electric wire protruding pipe is caused to  project to place the end of an electric wire in the position of a wire hold- down member 13. An air  cylinder 12 is driven to pinch the end of the wire between the hold-down member 13 and the bottom of an upper flange 8. A driver is then energized to rotate a lead winding model 11, an a top  plate 16 and a winding model 20 together. In the position of half rotation, a traverser is driven  upward to lift the electric wire above the upper flange 8. When a prescribed number of times of  rotation is performed, the driver is deenergized and an air cylinder 18 is driven and a winding  model holder 19 is elevated. At that time, the distance between the bottom of the winding model  20 and the top of the upper flange 8 is increased. In the final stage of elevation, a stripper pin 22  is protruded from the bottom of the winding model holder 19. At that time, the bottom of the pin 22 is wound on the peripheral surface of the winding model 20 to push the electric wire down and  separate it from the winding model. After that, the electric wire is cut off and the wire hold-  down member 13 moves down.
