Title: Chopper type mos comparator
Inventor: KATOU MITSUHARU
IPC: H03K5/24
Filed: 1981-06-08
Abstract: PURPOSE:To increase the operating speed, by providing an input voltage storage capacitor, in a chopper type MOS comparator. CONSTITUTION:A reference voltage Vr is applied to one end A of a capacitor 16 via a switch 13 and an input voltage Vs is applied to it via a switch 14. Another end of the capacitor 16 is connected to an input terminal B of a CMOS inverter 17 and a switch 11 is provided between input and output terminals B and C of the inverter 17. When the switches 11 and 13 turn on and switches 12 and 14 turn off, a potential at the terminals B and C is a threshold voltage of the inverter 17. When the switch 13 turns off and the switch 14 turns on after the switch 11 turns off and the switch 12 turns on, a potential at the terminal B is changed in accordance with the difference between the Vr and Vs, an output of the inverter 17 goes to H or L. Since a capacitor for the input voltage storage is connected to an input terminal E, a timing signal for switch driving can be quickened.

Filed: 1986-04-16
Abstract: PURPOSE:To form the titled device capable of deflect waveguide light two-dimensionally, and small in size, by providing a diffraction grating for turning back a diffracted waveguide light and diffracting it so as to advance to a substrate side, and providing the second deflecting means for deflecting the turned-back waveguide light in the laminating direction of the substrate and the optical waveguide. CONSTITUTION:A surface acoustic wave 16 advances in the direction as indicated with an arrow B on the surface of an optical waveguide 11, and advances so as to cross the acoustic wave 16, but in that case, it is brought to Bragg diffraction. A deflected waveguide light 21 is coupled to an aggregate diffraction grating FGC 15, and changed to a wave what is called a backward wave and turned back toward a substrate 12 side. The light beam 21 which is made incident into the substrate 21 passes through a pair of electrodes 17a, 17b and a part opposed to their gap, but changes its light refractive index by receiving the heat by an electric field, therefore, refracted in the direction as indicated with an arrow D. The light beam 21 which is emitted from an end face 12a is deflected continuously in the direction as indicated with an arrow Y, and also, by a diffraction by the surface acoustic wave 16, the light beam concerned 21 is deflected continuously in the direction as indicated with an arrow X, too, in the outside of the substrate 12. Accordingly, when a body to be scanned 25 is placed in a position where this light beam 21 is irradiated, the body to be scanned concerned 25 is scanned two-dimensionally by the light beam 21.

IPC: B21B37/18
Filed: 1989-04-06
Abstract: PURPOSE:To control the variation of tension of a strip on the inlet side with a high responsiveness by moving the positions of deflector rolls guided through a die means based on information about the thickness of the strip on the inlet side of main rolling rolls. CONSTITUTION:The passing locus of the strip A uncoiled from an uncoiling reel 20 is bent by the deflector rolls 13, then, the strip A is rolled by the main rolling rolls 24. The control means anticipates the variation of tension based on information regarding the thickness of the strip A brought into the main rolling rolls 24, the deflector rolls 13 are guided by a guide means according to this variation of tension and moved to a prescribed position.

Title: Air conditioning device for vehicle
Inventor: HONDA YUJI
IPC: B60H1/00
Filed: 1991-03-26
Abstract: PURPOSE:To control the quantity of blow-off air into a car room without depending on a water temperature sensor in response to the detection results of the blow-off air temperature into the car-room by a blow-off outlet temperature sensor in a case where hot air is required to be blown into the car room with a heat source not sufficiently heated at the time of start-up. CONSTITUTION:A microcomputer 150 determines the required blow-off temperature of blow-off air flow in response to the actual temperature and the set temperature, and controls the blow-off air flow so that the actual temperature in the car room is maintained at the set temperature. When it is judged that warm-up control is needed in answer to the above blow-off temperature needed to be determined, and when the temperature detected by a lower blow-off outlet temperature sensor 130 is very low, the microcomputer 150 stops a blower 30, and allows the air to be blown from the blower 30 into the car room at intermittent time-intervals in response to the temperature detected by the lower blow-off outlet temperature sensor 130.

Title: Picture processor
Inventor: NOGUCHI YASUSHI
IPC: H04N7/01
Filed: 1993-03-22
Abstract: PURPOSE:To generate a same display picture even when a system of a display device differs by generating data of odd or even number fields from picture data of two lines and feeding back the data in a succeeding field. CONSTITUTION:When a system of a display device differs from that of a talking object, picture data of two lines are subjected to weighting addition and picture data are generated. In this case, an interpolation circuit 41E generates picture data of an odd number field or an even number field for each one field period and stores the data sequentially to an FIFO 42. Then the picture data stored once are fed back to the input side in a succeeding field and stored newly and sequentially. Thus, a picture data processing section converts the line number of the picture data stored in the FIFO 42 and outputted from an arithmetic operation memory 40 for one field period. Thus, the picture data are alternately generated in the unit of field in synchronism with a write timing of the FIFO and the same display picture is generated even when the system differs.

The quantity of the energization for the heater 2 is then gradually reduced to naturally cool the crucible 5. When the temperature is reduced to room temperature, the crucible 5 is lowered to take out the fluoride crystal 100.  In the case of calcium fluoride, the preferred heat treating temperature is >=1,000 deg.C and the melting point of the calcium fluoride or below.

A compound expressed by formula II (m is 0-6) is subsequently separated from the organic layer and the aqueous layer is then reused for the condensation reaction. Although the unreacted raw materials, intermediates, product, by-products, etc., are contained in the aqueous layer, they are in trace amounts. Thereby, circulation and reuse for a long period can be carried out effectively tn prevention of pollution.
