Title: Monitor output device for high density television (hd-tv) receiver
Inventor: LEE KAB-KEUN
IPC: H04N9/64
Filed: 1998-04-13
Abstract: PROBLEM TO BE SOLVED: To enable an HD-TV receiver to execute a video recording of an HD-TV broadcasting program by an NTSC-VTR by converting a digital HD video signal into a specified display type of output chrominance signal and further converting it into an NTSC luminance signal and a chrominance signal. SOLUTION: A format converter 128 converts an HD video signal from an HD decoder 118 into a specified display type of primary color signals R, G and B. A HD/NTSC converter 140 converts primary color signals R, G and B from the format converter 128 to a luminance signal Y of an analog NTSC and a chrominance signal C. A second mixer 142 mixes the luminance signal Y with the chrominance signal C and generates a composite video signal V. The composite video signal V, the luminance signal Y and the chrominance signal C are outputted by way of a second switch 144. Thus, a user views an HD-TV broadcasting program on an HD-TV receiver, while also executing video recording by a VTR of the NTSC system.

Filed: 1989-04-21
Abstract: PURPOSE:To attain long service life of a back light and to reduce useless power consumption by detecting a synchronizing signal of an input video signal and turning off automatically the back light when the synchronizing signal is not detected. CONSTITUTION:When a video tape loaded on a video signal source 4, for example, comes its end and a video signal is not obtained for the reception channel, a luminance chroma separation circuit 16 cannot extract the synchronizing signal and a vertical synchronizing signal V is not fed to a light control circuit 20. Thus, a charge level of a capacitor 22 is lowered, a transistor(TR) 25 is turned off, and its collector level goes to a high level. Thus, a high voltage drive circuit 31 stops the production of a high voltage signal and the back light 32 is turned off. Thus, useless lighting of the back light 32 is prevented, then useless power consumption of a display device is prevented and power consumption is reduced.

Title: Tire load controller with drift compensating function
Inventor: NAGAI HIDENORI
IPC: G05B11/36
Filed: 1979-08-13
Abstract: PURPOSE: To reduce an overshoot or undershoot by stopping drift compensation in a transient control state and then by putting it into effect when the stationary state  is neary set.  
     CONSTITUTION: When deviation ΔT of the output signal of load setter 1 from that of load cell amplifier 4 connected to load cell 3 is large, namely, in a transient state, neither voltage comparator 6 nor relay 7 is not in operation. Therefore, contacts 8 and 9 are open and closed respectively and integrator 10 is reset, generating no output voltage. When deviation ΔT is small, i.e., when the control is getting stationary, comparator 6 and relay 7 are both put into operation and integrator 10 starts operation. Therefore, if load controller 2 generates an error in the stationary state, the drift compensator starts operation for the control so that deviation ΔT will be zero. Thus, the overshoot or undershoot can be reduced.

Abstract: PURPOSE:To make the consumption current and the lowest operating voltage constant with respect to temperatures and to reduce the consumption current, by supplying a constant voltage to a part of CMOS.IC via a resistor which has been formed concurrently with P-Well diffusion. CONSTITUTION:The output of a battery 7 is converted into a constant voltage by a constant voltage circuit 6.

The battery voltage is directly applied to a display driving part 3. If the temperature is increased, the value of the diffused resistor 101 is increased and the current is restricuted. If the temperature is decreased, the resistance value is decreased and the current is increased. Therefore, the consumption current and the lowest operating voltage 1 of the circuit becomes constant.

Abstract: PURPOSE: To enable smooth taking-up of cord and maintain safety by arranging a cavity for setting the cord curvature part in free state, which sets-up at the cord introducing part in the hanging-down of the cord, when the cord is taken-up, and reducing the sliding resistance.  
     CONSTITUTION: When the cord 8 taken-out hangs down, the cord 8 contact with the upper collar part 11b and a cord port 4 at the cord introducing part, and as the diameter of the upper collar part 11b is made smaller than the lower collar part 11a, forming a gap G, the cord 8 perfectly pulled-out is taken-up on a reel 7 against the sliding resistance generated, due to the contact with the upper collar part 11b and the cord port 4, by the maximum rolling-back force stored in a spring 6. However, when the cord 8 is taken-up to a certain degree and the rolling-back force of the spring 6 decreases and the speed of revolution of the reel 7 decreases, the cord curvature part W does not contact with the upper collar part 11b, owing to the cavity G, and the sliding resistance decreases.

Abstract: PURPOSE:To prevent adhesion of films to each other and to obtain transparency by adhering mixture of organic silicon compound solid fine particles and water soluble polymer having non-adherence at the ambient temperature at least on one side surface of a soft vinyl chloride resin film at a specific ratio per unit area CONSTITUTION:A mixture of organic silicon compound solid fine particles and water soluble polymer having non-adherence at the ambient temperature is adhered to at least one side surface of a soft vinyl chloride resin film at 0.01-3g/m<2> per a unit area of the film thereby to form a soft vinyl chloride resin film for an agriculture.

Title: Ink tank for ink-type wire dot printer
Inventor: MATSUZAWA MASANAO
IPC: B41J2/255
Filed: 1984-05-22
Abstract: PURPOSE:To arrange so that ink inside a tank may be completely used by arranging plural ink-impregnated members having varying capillary capacity in such a way that the capillary capacity gradually increases to the nearest member to the ink supply port. CONSTITUTION:When the ink is consumed completely, the ink in a porous member 62 flows into a printer head body through an ink guide groove 12b of an ink supply guide arm and a thin groove 45 of a tank bottom stepped part 44. At that time, the moving quantity of the ink in the porous member is negligible and therefore, almost no ink blocking occurs, because the ink movement is in the thickness direction of a plate-like porous member 62. Furthermore, if the ink is exhausted, a differential in the internal pressures of a porous member 61 and the porous member 62 generates immediately due to the difference of an average nozzle diameter. Thus the uninterrupted ink supply equivalent to an ink consumption from the porous member 61 to the porous member 62 results.

Title: Application device of viscous material

IPC: B05C11/10
Filed: 1994-05-17
Abstract: PURPOSE:To apply a viscous material at a specific flow and accurately regardless of a change in the temperature in an application device the viscous material which controls a flow path by the rotary speed of a pump of fixed volume type. CONSTITUTION:An application head 2 is equipped with a resistance variation means 7 which consists of a screw-type pin 70 with a spiral groove 70a on the outer periphery for engagement with a nozzle 20 to change a flow path resistance and drive sources 72, 73 which move the pin forward and backward and also rotate it. The pin 70 is caused to recede, if the temperature of the viscous material is low so that the flow path resistance is reduced, and is caused to advance, if the temperature is high so that the flow path resistance is increased. If the viscosity changes due to a temperature variation, the discharge load of a pump is constant, and a fault such as a change in the flow due to the varying internal leak amount of the pump by a load variation does not occur. In addition, the push and pull force of the viscous material ensuing from the forward/backward movement of the screw-type pin 70 is offset by a pumping effect generated by the rotation of the pin 70, so that no flow variation at the time of pin drive occurs.
