Title: Chrominance signal processor
Inventor: FURUHASHI MICHIO
IPC: H04N9/47
Filed: 1981-09-26
Abstract: PURPOSE:To ensure the accurate identification of lines even in a reception mode of a weak electric field, by switching the central frequency of a band filter which extracts the carrier chrominance signal of SECAM system between the horizontal scan period and the horizontal flyback time. CONSTITUTION:The carrier chrominance signal component or a composite color TV signal fed through a terminal 20 is supplied to a band pass filter 12 via a capacitor 21 and then applied to a parallel resonance circuit including a coil 22 and a capacitor 23. In addition, a series circuit of trsnsistors (TR) 26 and (TR)  27 and another series circuit of a capacitor 28 and a resistance 29 are set in  parallel to the above-mentioned parallel resonance circuit. Then the horizontal flyback pulse is applied to the bases of the TRs 26 and 27 with the polarities as  shown in the diagram. As a result, the TR26 breaks and conducts in the horizontal flyback time and the horizontal scan period respectively, and vice versa  with the TR27. In such way, the filter 12 can have different characteristics of  band between the horizontal scan period and the horizontal flyback time. This  can increase the accuracy for the line identification.

Title: Controller for dc motor
Inventor: ASAEDA TAKEAKI
IPC: H02P7/29
Filed: 1982-08-31
Abstract: PURPOSE:To improve the speed controlling performance by varying the switching frequency of a chopper in response to the outer signal level of a current controller. CONSTITUTION:A speed controller 61 outputs as a current reference signal the deviation between a speed reference and a speed detection signal, and a current controller 62 outputs the deviation between a current reference and a current detection signal. A function generator 641A outputs a signal which decreases in proportion to the output of the controller 62 when the output is small and which is constant when the output is higher than the prescribed level. A V/F converter 642 applies a pulse of the frequency proportional to the output signal of the generator 641A to a triangular wave generator 632. A comparator 631 controls the conducting period of a transistor 21 of a chopper 2 in response to the compared result of the triangular signal from the generator 632 and the output signal of the controller 62. In this manner, the performance of speed control can be improved.

Inventor: INUZUKA TADASHI
IPC: A47J27/21
Filed: 1989-06-15
Abstract: PURPOSE:To obtain an electric kettle not decreasing pouring quantity even during boiling and just after boiling by providing a centrifugal pump, for which one end is communicated through a water guide pipe to the other end of a pouring port opened in the external part of a main body, to be communicated with a container, and providing a switching valve to arbitrarily and alternatively open a circulating duct, which is communicated with the container, and the water guide pipe to be communicated to the pouring port in the middle of the water guide pipe. CONSTITUTION:Hot water in a container 1 is guided from a communicating metal fitting 10, which is provided in the buttom part of the container 1, through a centrifugal pump 13 to a switching valve 15 and by the operation of this switching valve 15, the hot water is passed through a circulating duct 14 and circulated from the upper part of the container 1 into the container 1. Bubbles in the hot water is liquefied with the reduction of a hot water temperature and almost extinguished. In such a state, when an operation knob 20 is turned and the centrifugal pump 13 is electrified, the switching valve 15 immediately opens the side of a water guide pipe 12, which is communicated with a pouring port 17, and the hot water in the container 1 is guided from a communicating metal fitting 10 through the water guide pipe 11 into a case A21 of the centrifugal pump 13. Since the quantity of the bubbles to be generated by the rotation of a fan wheel 24 is reduced as much as possible, the quantity of the hot water to be poured even during boiling and just after boiling is not changed at all in comparison with the quantity at the time of insulating heat at 95 deg.C.

IPC: G06F19/00
Filed: 1995-06-20
Abstract: PURPOSE: To increase automatically the luminance of a cathode ray tube display monitor in an active state used for generic persons such as a bank terminal like an automatic cash dispenser. CONSTITUTION: A sensing section 1 senses access of a person thereto, and a sensing section provides an output of a sensing signal S1 when the access is sensed. Based on the sensing signal, a 1st grid voltage setting circuit 2 increase a 1st grid (G1) voltage of a cathode ray tube 6 to increase the luminance and uses a 2nd grid voltage setting circuit 4 to decrease a 2nd grid voltage for preventing a floated level of a background of a video image and uses a focus voltage setting circuit 5 to select a focus voltage for correcting fluctuation of a focal point. Thus, the luminance is increased while preventing deteriorated image quality. When the access of a person is not sensed, 1st and 2nd grid voltages are set to decrease the luminance more than that when the access is sensed. Moreover, a focus voltage is set to a voltage suitable for the luminance.

Title: High-frequency hardening method
Inventor: ONISHI MASAZUMI
IPC: C21D1/10
Filed: 1986-06-30
Abstract: PURPOSE:To increase hardening depth without hardening the core part of steel products by executing quick cooling after heating in two stages at the time of high-frequency hardening of the steel products. CONSTITUTION:While the steel products 5 to be treated are passed in a heating coil 2, the steel products are heated up to the hardening temp. by the induction electric power by the coil 2; thereafter, the steel products are cooled by the cooling liquid 7 injected from a sprinkler 6 of a 1st ring 3a for the cooling liquid. The steel products are then cooled by the cooling liquid 7 sprayed from the sprinkler 6 of a 2nd cooling ring 3b apart at about 10mm from said sprinkler 6. The flow rate of the 1st cooling liquid 7 is adjusted to about 0.4l/min.cm<2> and the flow rate of the 2nd cooling liquid 7 to 1.4l/min.cm<2>. (The unit is the flow rate of the cooling water to be injected per cm<2> of the steel products 5.) Only the surface layer is cooled with a small amt. of the cooling liquid in the 1st cooling. Heat transfers into the deep part of the steel products 5 before the steel products move to the 2nd cooling position. The surface is thereafter quickly cooled again; therefore, the hardening to the deep hardening depth is executed without hardening the core part.

IPC: H01F41/04
Filed: 1988-06-22
Abstract: PURPOSE:To make it possible to obtain an inductance element which is a further miniaturized and thinned closed magnetic circuit type by constituting ferrite powder to be mingled in resin out or powder having specific particle diameters, and sealing it with resin to which this ferrite powder is mingled. CONSTITUTION:Ferrite powder consisting of powder having particle diameters of 20-210mum for the most part is mixed and kneaded with synthetic resin 7, and this mixed and kneaded substance is used to seal a core vacant coil 5 or a magnetic core contained coil 5 and these are solidified as occasion demands. For the ferrite powder, the coercive force lowers as the particle diameter becomes large, and the powder having large particle diameters is excellent as soft magnetic material compared with powder small in particle diameter. Hereby, as compared with the case that the conventional ferrite powder is used, it can improve inductance L more than 10%, if selecting conditions, more than 70%. Also, in case that the inductance L is made to be equal, it can make small the size of the element, especially the height more than 10%, if selecting conditions, more than 70%.
