Title: Liquid crystal device
Inventor: YOSHIDA AKIO
IPC: G09G3/36
Filed: 1999-12-13
Abstract: PROBLEM TO BE SOLVED: To cope with television broadcasts and to actualize infinite gradations by driving an antiferroelectric liquid crystal without using the memory properties of the antiferroelectric liquid crystal. SOLUTION: The antiferroelectric liquid crystal is driven without using the memory properties of the antiferroelectric liquid crystal or an antiferroelectric liquid crystal having no memory property is provided and applied with high- voltage pulses. Namely, one scanning period wherein a scanning signal GK is on is divided into a 1st time and a 2nd time. In the 1st time, an auxiliary pulse application signal GH is turned on to applying an auxiliary pulse high voltage VH. In this period, a sample holding circuit SH is disconnected. Then the auxiliary pulse application signal GH is turned off in the 2nd time and a gradation voltage Vs1 or Vs2 is applied from the sample holding circuit SH. Consequently, when an antiferroelectric liquid crystal device is controlled with voltage, the speed of transition from an antiferroelectric state to a ferroelectric state can be made greatly fast.

Filed: 1998-12-11
Abstract: PROBLEM TO BE SOLVED: To suppress the rotation irregularity of a driven magnetic wheel body, and to improve the interlock torque of magnetic interlock in a magnetic interlock device and an image-forming device using it.

Abstract: PURPOSE:To improve the radiation pattern of an electromagnetic wave by changing a high frequency current distribution on a housing by providing a recessed part on the shielding means of a portable radio equipment. CONSTITUTION:A notch 101 is provided in the neighborhood of 1/4 wavelength (dimension 1) from the setting point of an antenna 103. The length (a) of the notch 101 is almost the 1/4 waveform. At that time, the length from the top end part of the antenna 103 to the notch 101 is almost 1/2 waveform by an electric length conversion. Therefore, the current distribution indicates the waveform of a broken line (a) at that part. Then, the length of the notch 101 is almost 1/4 waveform, and then the current distribution at the upper side part and lower side part of the notch 101 is the waveforms of broken lines (b) and (c). At that time, the amplitude of the broken lines (b) and (c) is the same, and the phases of the lines (b) and (c) are opposite, so that an influence on those electromagnetic wave can be offset. That is, the influence of the portable radio equipment on the electromagnetic wave radiation due to the notch 101 can be prevented, the influence of the high frequency currents running on the housing on the radiation can be reduced, and the desired radiation pattern can be obtained.
