Abstract: PURPOSE:To improve the duty ratio and display performance of an image display device by selecting the potentials of a common electrode and one common- connected electrode of storage capacity so that variation in the potential of picture element electrodes regarding a driving signal and a transistor and the constitution of picture elements is compensated. CONSTITUTION:The capacity between the gate of the transistor 7 and a picture element electrode 9 is denoted as CGD, the storage capacity with the picture element electrode 9 is denoted as CS, and the voltage of the common electrode 10 which is inverted periodically is denoted as V. Then when the potential of the common electrode 10 is varied, the potential of one common-connected electrode of the storage capacity 8 is varied in the same direction with the common electrode 10 nearly by a voltage (1+CGD/CS)V. A voltage applied to liquid crystal before and after the potential variation of the common electrode 10 and storage capacity 8 is held equal because of the uniformity of driving voltage conditions over the entire screen of a liquid crystal display body. Consequently, 100% duty AC driving is enabled and the display quality is improved.

Title: Optical switch
Inventor: NAKANO YOSHIHIRO
IPC: H01H35/00
Filed: 1987-04-30
Abstract: PURPOSE:To make the operation stable and the transfer speed quick by providing a liquid crystal element arranged on the transmission path of an optical fiber and varied to the opaque or transparent state by the voltage change. CONSTITUTION:An optical switch is constituted of a liquid crystal element 2 and a control voltage signal line 3. When the optical signal is to be out off, the electric signal required to make the liquid crystal element 2 opaque is fed from the control voltage signal line 3. When the liquid crystal element 2 becomes opaque, the optical signal is absorbed by the liquid crystal element 2 and is not transmitted to the output side of an optical fiber 1. The optical switch thereby indicates an off state. When the optical signal is to be allowed to pass, a signal is sent via the control voltage signal line 3 to change the liquid crystal element 2 into a transparent state from the opaque state. As a result, the optical signal in the optical fiber 1 passes through the transparent liquid crystal element 2 and is transmitted to the output side 5 of the optical fiber 1. The optical switch indicates an on state accordingly.

Title: Air-cooled radiator
Inventor: AOYANAGI TORU
IPC: F28F1/40
Filed: 1994-05-20
Abstract: PURPOSE:To provide an air-cooled radiator in which the radiating rate can be regulated to be increased or decreased without increasing jarring fan noise. CONSTITUTION:An air-cooled radiator comprises a cylindrical radiator body 1, a heat storage drum 2 slidably coupled into the body 1, a base 3 coupled to the end face of the drum 2, and a heat generation source 4 placed on the upper central part of the base 3.
