Filed: 1995-08-11
Abstract: PROBLEM TO BE SOLVED: To make it possible to reduce the electric power consumption of a gradation voltage forming circuit forming many gradations of gradation voltages by specifying the circuitry construction of this gradation voltage forming circuit. SOLUTION: The rear stage of the gradation voltage forming circuit forming the many gradations of the gradation voltages is provided with a first switching element Sc and second switching element Sg of which the terminals at one side are connected to pixel electrodes and the terminal on the other side are inputted with power supply voltage and reference voltage. The first switching element Sc or second switching element Sg is alternately conducted in the prescribed period from the time of the voltage inversion to invert the gradation voltage to be impressed on a drain signal line in synchronization with a current alternating signal, by which the liquid crystal layer is precharged to the power supply potential when the common driving voltage Vcom to be impressed on a common electrode is at an H level and to the reference potential when the common driving voltage is at an L level.  The charging and discharging currents flowing to the liquid crystal layer are decreased via the gradation reference voltage source forming the gradation reference voltage and the drain driver.

IPC: H01L21/314
Filed: 1990-08-01
Abstract: PURPOSE:To obtain a high reliabile edge emission type semiconductor laser device capable of operating at high power by bringing the end face of an oscillator formed by wafer etching in contact with a sulfer-contained solution and growing a semiconductor layer whose forbidden band width is larger than an active layer on the surface of the oscillator's end face. CONSTITUTION:An n-GaAs current constriction layer 302, a pAl0.45 Ga0.55 As first clad layer 303, a p-Al0.55 As active layer 304, an n-Al0.45 Ga0.55As second clad layer 305, and a GaAs contact layer 306 are arranged to grow successively, thereby preparing an internal stripe type VSIS water. Te wafer is etched so that a stripe groove 320 may be formed vertically to the direction of optical waveguide, which forms a mirror surface-like oscillator end face 307. The wafer is dipped in a 10% aqueous solution 308 of (NH4)2S where the surface on the end face of the oscillator is processed. Then, the temperature is increased in an AsH3 gas atmosphere so that the sulfur sticked to the end face of the oscillator may be subliminated and cleaned. This construction grows a highly resistant non-doped Al0.5 Ga0.5 As layer 309. This layer is adapted to have larger forbidden band-width compared with the active layer.

Abstract: PROBLEM TO BE SOLVED: To automate radio frame synchronization between all base stations within a specified service area without utilizing a communication signal transmitted by a user's mobile equipment within the radio zone of a base station by adjusting the radio frame phase of an adjusting station so as to phase-synchronize with the radio frame of a reference station based on an obtained phase difference. SOLUTION: A managing part 51 obtains one of the base stations to synchronize as the reference station 60 and the other as the adjusting station 61 and requires the reference station 60 to transmit/receive a signal between with a testing mobile equipment 62. Furthermore the managing part 51 requires the adjusting station 61 to intercept this communication signal to detect the radio frame phase of the reference station 60 from this communication signal to measure the phase difference of the radio frame between the reference station 60 and the adjusting station 61 to send back the measured phase difference.  A phase adjusting part 52 sends the adjusting instruction of the radio frame phase to the adjusting station 61 so as to attain radio frame phase synchronization between the reference station 60 and the adjusting station 61 based on the phase difference sent back from the adjusting station 61.

Title: Lens cover driving device
Inventor: KAJI EISHIN
IPC: G03B17/04
Filed: 1994-08-31
Abstract: PURPOSE: To prevent a lens cover or a transmission member from being deformed and broken by providing a cushioning member acting by driving force and force contrary to the driving force at a part of the transmission member. CONSTITUTION: The driving force generated by an electric motor is transmitted to a gear 37. By the driving force of the electric motor and the elastic force of a driving spring 54, an intermediate lever 53 caulked by the gear 37 rotates. One end of an internal force spring 56 is engaged with the intermediate lever 53. The rotational force of the intermediate lever 53 is applied to the one end. By the rotational force, one end of the internal force spring 56 rotates in the rotating direction of the intermediate lever 53. Also, the other end of the internal force spring 56 is engaged with a cover 30. External force applied to the cover 30 is applied to the other end. Then, the external force prevents the displacement of the other end. Consequently, the other end engaged with the cover 30 is made to be in a stop-state.  Thus, the internal force spring 56 is elastically deformed and is made to be in a twisted-state centering a shaft 38, and then, a load is not applied to the cover 30 at all.
