Title: Solenoid driving circuit
Inventor: YAMANISHI HIDEKAZU
IPC: H01F7/18
Filed: 1986-04-25
Abstract: PURPOSE:To reduce the size of a solenoid driving circuit by continuously outputting a control signal when a solenoid attracts, and intermittently outputting it when the solenoid sticks to decrease power consumption and the amount of heat generated with a simple configuration. CONSTITUTION:When a CPU 11 supplies a control signal to a solenoid 14, an input/output circuit 12 outputs a drive signal (a) to a driver 13. The signal (a) continuously becomes a low level during a predetermined period that the solenoid 14 needs to attract, and then repeats high and low levels. As a result, a transistor TR1 is turned OFF and a transistor TR2 is turned ON at attracting time so that a current I1 continuously flows to the solenoid 14. Since the TR1, TR2 repeat ON and OFF at the time of sticking, the current I1 and a circulating current I2 alternately flow to the solenoid 14. Thus, power consumption at the time of sticking is reduced, and the amount of heat generated is decreased. The size of the circuit can be also reduced.

Title: Fast dubbing tape recorder
Inventor: MAKIMOTO SHINJIROU
IPC: G11B15/00
Filed: 1984-05-16
Abstract: PURPOSE:To realize high performance and fast dubbing by holding a dubbing speed high, and performing direction inversion at a tape end at a normal speed and stopping other mechanisms in a stand-by state during said direction invertion. CONSTITUTION:When a magnetic tape loaded in a fast deck 1 comes to its end, the magnetic tape end is detected by a detector 3, whose signal is sent to a controller 4. The controller 4 sends a stop command to a reproducing deck 1 and a sound deck 2, which are both stopped. Then, the controller 4 places the deck 2 in normal-speed direction inverting operation and commands the decks 1 and 2 to enter a fast dubbing mode and then perform fast dubbing operation again.

Title: White balance adjustment system for color television camera
Inventor: HONBO MASANORI
IPC: H04N9/73
Filed: 1990-04-13
Abstract: PURPOSE:To always maintain satisfactory picture quality by adjusting again the gains of respective original color picture signal channels with the signal of a highest level among three original color picture signals obtained at the time image-picking up a white subject as a reference signal. CONSTITUTION:The gains of gain control circuits 6 are changed into rated gains for three channels of R, G and B and the white subject 1 is image-picked up. Respective gains of the gain control circuits 6 are changed again so that the levels of the other signals agree with the signal of the highest level among the output signals ER, EG and EB of respective gain control circuits 6 and white balance is adjusted. Thus, the gains of the gain control circuits 6 of respective color channels always take values at least more than the rated value and the upper limit values of respective levels of the output signal ER, EF and EB from the gain control circuits 6, namely, the dynamic ranges of respective channels of R, G and B can always be held larger than the rated value.

Title: Manufacture of silicon solar cell
Inventor: MATSUMOTO HITOSHI
IPC: H01L31/04
Filed: 1979-07-27
Abstract: PURPOSE:To obtain an extremely low-cost silicon solar cell in a simple manner, by giving rise to precipitation by piling low-resistance and high-resistance silicon films on a metallic substrate in layers by electric plating in a silicon-compound-containing water-free plating bath. CONSTITUTION:The invention is based on a concept that a high-capability solar cell can be obtained even by using a silicon film prepared by electric plating process. That is, SiCl4 and (C4H9)4NBF4 are added to a solution of dimethylformamide, and this is agitated in a dry nitric atmosphere to prepare a plating bath. And then, a platinum plate (or sheet) which is to become an anode and a stainless steel substrate which is to become a cathode are immersed in the plating bath, and by agitating the bath while impressing DC voltage, B is doped on the stainless steel substrate and a low-resistance silicon film is precipitated. And then, only SiCl4 is added to a methylformamide, and a high-resistance silicon film is precipitated on the low-resistance silicon film in the same manner. It is possible, in this manner, to manufacture a solor cell with a conversion efficiency at 4% by a very simple process.

When the liquid surface is between both sensors, the voltage v1 is lower than the voltage V2, and the output voltage of the terminal 10 is Vec to continue the liquid supply. When the upper limit liquid level sensor is under the liquid surface, the voltage V1 is higher than the voltage V2, and the output of the terminal 10 is zero, and the liquid supply is stopped. When the liquid surface attains under the lower limit sensor, the liquid supply is restarted.

Title: Radio receiver
Inventor: HORIIKE YOSHIO
IPC: H04B1/26
Filed: 1982-06-07
Abstract: PURPOSE:To increase SN even if electric field strength is weak, by changing the band width of an intermediate frequency amplifier circuit in accordance with an input signal level. CONSTITUTION:The intermediate frequency 1F amplifier circuit 5 is provided with two filters of wide and narrow bands, e.g. 250KHz and 150KHz e.g. The output of the 1F amplifier circuit 5 is applied to a stereophonic demodulating circuit 7 and a level detecting circuit 12. When the output of the circuit 5 is reduced in a weak electric field, the stereophonic demodulating circuit 7 is controlled to deteriorate separation between stereophonic signals and turn to monophonic reception. When the output level of the circuit 5 is reduced to lower than a level, the circuit 12 is switched to the narrow band filter, and at the level, a titled receiver has been already switched to the monophonic reception. Since the narrow band filter is used in the weak electric field, the threshold level is reduced. Since the receiver has been already switched to the monophonic reception in the weak electric field, the generation of large distortion is suppressed.

IPC: G11B5/027
Filed: 1982-06-07
Abstract: PURPOSE:To simplify the operation of dubbing, by controlling two control means, a switching means a control means thereof in mutal relation. CONSTITUTION:The control means 3 gives a rewinding instruction to the control means 106 and 206 when the means 3 is operated to control decks 1, 2 in the rewinding state. When tapes 110, 210 are rewound up to the beginning of tape, an output is produced and the control means outputs a constant-speed running or reproducing instruction for a prescribed time. When the instruction is applied to the control means 106, 206, the tapes 110, 210 are driven in a constant speed or reproduced for a prescribed time. The control means 3 selects a switch means 7 to a contact (b). Thus, the input of a recording means 8 is an amplitude corresponding to an output of a reproducing amplifier means 4 divided with a level setting means 6, and a level recorded on the tape 110 corresponds to a level to be recorded on the tape 210. Thus, the recording level is set automatically, allowing to simplify the operation.

Filed: 1978-08-11
Abstract: PURPOSE: To perfectly insulate a coil from a bearing, by providing recesses on the part of a mold corresponding to the coil, which is likely to move when a molding resin is injected, so that the distance between the coil and the bearing is maintained.  
     CONSTITUTION: The recesses 10 are provided in the part of the mold corresponding to the coil 9, which is likely to move due to the pressure of the molding resin when the resin is injected. An appropriate gap G is thus formed between the coil 9 and the bearing 4 after the resin is injected. The gas G is set at 0.8 to 2.5 mm depending on a desired insulating capability. Even if the coil 9 is displaced by the injection pressure of the molding resin, the coil does not come into contact with the bearing 4. The insulating capability is thus attained.
