Title: Driving method for liquid crystal element
Inventor: ITO AKIHIKO
IPC: G09G3/36
Filed: 1988-01-13
Abstract: PURPOSE:To improve the color balance and to improve the contrast by allowing an applied voltage to conform to a color whose threshold level is the lowest at the time of turn-off of a liquid crystal element and adding and applying prescribed pulse width to a turn-on pulse by a difference of the threshold level at the time of turning on the liquid crystal element. CONSTITUTION:A signal electrode waveform is formed by inputting a gradation signal to SEG1-SEGn and switching an analog switch 207. Also, an effective value of a voltage pulse which is applied at the time when a liquid crystal element if all turn-off is set to the vicinity of a threshold voltage of a color whose threshold level is the lowest in advance, and when gradation data becomes turn-on even one bit, a prescribed turn-on pulse corresponding to a difference of the threshold levels of every color is applied. That is, light transmittivity of a black level at the time of turn-off of the liquid crystal element is suppressed as low as possible, and also, when the gradation data is turned on even one bit, as for the color whose threshold level is high, the liquid crystal element is driven by applying the width of the turn-on pulse by prescribed width so that an effective voltage rises by a portion of a high threshold level. In such a way, the color balance can be improved, and the contrast can also be improved.

Title: Device for coating agent on outer periphery of rodlike body
Inventor: MORII NORIO
IPC: B05C11/02
Filed: 1986-01-16
Abstract: PURPOSE:To reduce the wear of an elastic member and to operate the titled device for a long period by providing plural levers of specified shapes consisting of the elastic body to a coating agent feeder for excessively coating the coating agent on a rodlike body in front of the body in the moving direction. CONSTITUTION:The lever 12 is provided with plural or four elastic members 24, 26, 28, and 30, holders 32 for holding the members, fixed plates 34 for supporting respective holders 32, and springs 36 for connecting the holder 32 and the fixed plate 34. The elastic members 24, 26, 28, and 30 are formed in almost the same shape as the cross section of the rodlike body 22 to be coated, and have an opening having a cross section somewhat smaller than the cross section of the rodlike body. The two elastic members 24 and 26 close to the coating agent feeder 10 are formed with elastic sheet, and the two elastic members 28 and 30 distant from the device 10 are formed with a brush.

Title: Electron gun for cathode-ray tube
Inventor: YAMANE HISAKAZU
IPC: H01J29/50
Filed: 1990-01-12
Abstract: PURPOSE:To obtain a good white color balance at the time of image output by manufacturing a cathode support for a center and cathode supports for both sides out of Fe-Ni alloys slightly different in Ni content. CONSTITUTION:Each cathode support is manufactured out of Fe-Ni alloys containing 35-50% of Ni. At that time, the Ni content difference giving the maximum difference of thermal expansion coefficient is max + or -8% and therefore the Ni content difference among the Fe-Ni alloys for manufacturing the cathode support for the center 4b and cathode supports for both sides 4a, 4c should be set within the max + or -. Owing to thermal expansion, a G1 electrode is face- deformed toward a G2 electrode and the quantity is several mum and as shown in the figuar, the quantity of the thermal expansion of the support 4b in Z direction is slightly large as compared with that of the supports 4a, 4c. As a result, the gap between the support 4b and the G1 electrode and the gap between the supports 4a, 4c and the G1 electrode do not change and rising up of current of B and RG becomes almost the same and thus white balance becomes good.

Title: Ferroelectric liquid crystal display element
Inventor: SATO SHIGEHIRO
IPC: G02F1/1337
Filed: 1989-01-12
Abstract: PURPOSE:To form the element at a high yield without admitting the coloring of the element even if the thickness of the plural liquid crystal layers to specifying the angle of inclination of the liquid crystal layers from the normal direction of a substrate is increased. CONSTITUTION:The inclination of the liquid crystal layer is preferably >=45 deg. and <90 deg. from the normal direction of the substrate. The thickness of the liquid crystal film cannot be increased too much if the inclination of the liquid crystal layer is <45 deg.. The liquid crystal turns perpendicular to the substrate and the liquid crystal does not longer respond to electric fields at 90 deg.. Such inclination is, therefore, inadequate. The direction of the director of the liquid crystal is directed to the direction inclined by the angle beta from the substrate if the angle of inclination of the liquid crystal layer from the normal direction of the substrate is set at beta. The component which acts as an optical switch is the component projected to the substrate surface and, therefore, DELTAn cosbeta (DELTAn is the refractive index anisotropy of the liquid crystal) is obtd. and DELTAn can be effectively diminished. As a result, the increase of d (thickness of the liquid crystal layer) is possible. The liquid crystal thickness is increased to the thickness larger than the thickness when the liquid crystal layer is not inclined in this way and the yield is improved.

Title: Heat-sensitive inductor
Inventor: MIYAZAKI TAKESHI
IPC: H01F17/00
Filed: 1982-01-19
Abstract: PURPOSE:To improve heat-sensitivity by providing an annular magnetic bimetal with a gap and an inductance coil. CONSTITUTION:A magnetic body 2 with a small temperature coefficient and a magnetic body 3 with a large temperature coefficient are used to form an annular magnetic bimetal 1. The annular magnetic bimetal 1 is provided with a gap 4 and a coil 5 wound thereon. When the annular magnetic bimetal senses heat, the bimetal 1 is curved and spacing (d) of the gap is shortened because of the difference in temperature coefficient between both the magnetic bodies 2, 3, and the inductance of the coil 5 changes. By measuring or utilizing the change in the coil output as the result of the change in the inductance, it becomes possible to quickly sense the temperature change.

Filed: 1980-01-23
Abstract: PURPOSE:To generate a reference voltage having a large temperature coefficient, by amplifying a voltage, given a temperature coefficient by making use of a diode, by using an operational amplifier. CONSTITUTION:The inverting input (-) of operational amplifier 1 is provided with input resistance R1, feedback resistance R2 is connected between the inverting input (-) and output, and forward diode D1 is connected in series to input resistance R1 to apply voltage Vr stabilized through temperature compensation. Further, constant voltge V0 generated by dividing stabilized voltage Vr by resistances R3 and R4 is applied to noninverting input (+) of operational amplifying circuit 1 to develop reference voltage Vref at the output. Output reference voltage Vref can be found by solving equation I, where the forward voltage of diode D1 is denoted as VP. The temperature coefficient of reference voltage Vref can be set to a value multiplied by R2/R1 times. Consequently, a random large temperature coefficient can be obtained by properly setting the ratio of resistance R2/R1.
