Title: Liquid crystal display device
Inventor: MORISHITA SHUNSUKE
IPC: G02F1/13357
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To provide a structure having high strength to counter torsion and to provide protection of a power source circuit by providing at least a pair of respective opposite sides of the external shape of a casing viewed from an observation side with flank parts extending to the rear surface side. SOLUTION: The projecting parts 500A of which the respective sides parallel with the (x) direction of a resin frame 500 project along the respective sides are formed at the resin frame. Namely, the resin frame 500 is so formed that a pair of the respective opposite sides (the respective sides parallel with the (x) direction) of the external shape viewed from the observation side of the liquid crystal display device is provided with the flank parts 500B extending to the rear surface side. An effect of imparting the strength to the torsion by the rotating force of a reverse direction on the diagonal lines of the resin frame 500 may be imparted to the resin frame by such a constitution. Further, the strength of the casing composed by the combination of the resin frame 500 and an inside frame is made sufficient.  In addition, the flank parts 500B of the resin frame 500 are formed to a height taller than the height of a DC/AC inverter substrate. As a result, the constitution of the control substrate to a larger size is made possible.

Title: Photomask and production of photomask as well as etching method and exposing method
Inventor: INABA MANABU
IPC: G03F1/80
Filed: 1992-07-10
Abstract: PURPOSE:To decrease the number of processes and to improve throughput by forming a third intensity transmittance distribution with a distribution of the distances at which exposing light passes in an exposing light absorption region. CONSTITUTION:An absorption film 12 is formed by laminating a thin film of silicon dioxide on a quartz glass substrate 11 and further, a light shielding film 13 is formed on the quartz glass substrate 11 and the absorption film 12. Further, level differences are formed on the absorption film 12 and the distribution of the distances at which the quartz glass substrate 11 passes the absorption film 12 exist within the plane of the photomask. The exposing light is completely shut off and, therefore, the intensity transmittance is 0% and the light intensity is zero as well in the light shielding region where the light shielding film 13 is formed. The concn. of the boron ions incorporated into the absorption film 12 is constant throughout the film and the absorption quantity is determined by the distances at which the exposing light passes the absorption film 12. Since the intensity transmittance distribution is formed by the film thickness distribution of the absorption film 12, the intensity transmittance is reduced to 1/4 by doubling the film thickness of the absorption film 12.

Title: Telephone set sensitive to peripheral noise
Inventor: NAKAHARA TATSU
IPC: H04M1/60
Filed: 1986-08-05
Abstract: PURPOSE:To automatically adjust the sound volume of an incoming call at an appropriate level corresponding to the magnitude of peripheral noise by permitting a rectifying and smoothing means where a charging time constant is set larger than a discharging time constant to rectify and smooth a noise detection signal, and changing and controlling the level of an incoming call signal. CONSTITUTION:A microphone amplifier 8 amplifies noise collected by a microphone 7 built-in a telephone set 10. The rectifying and smoothing circuit 9 converts the noise to a DC voltage value in proportion to the level of its sound pressure, and inputs the converted one to a multiplier circuit 6. The rectifying and smoothing circuit 9 with charging in a long time and discharging in a short time outputs a voltage roughly equal to the level of peripheral noise independent of sound that human being speaks and sudden noise. Thus, as the peripheral noise becomes larger, the voltage value of the rectifying and smoothing circuit 9 is boosted, and the output of the multiplier circuit 6 becomes larger than multiplication. The sound volume of the incoming call signal rises because said signal drives a speaker 5 through a speaker amplifier 4.

Title: Electrolytic cell
Inventor: ITOI EIJI
IPC: C25B9/19
Filed: 1980-12-26
Abstract: PURPOSE:To reduce electrolytic cell voltage without degrading electric current efficiency by bringing either one of the opposite side faces of anodes and cathodes contacting an exchange membrane into contact with a a spring-like conductive member in an electrolytic cell for an aq. alkali chloride salt soln. by a cation exchange membrane method. CONSTITUTION:Anodes 1 are connected electrically and mechanically to an anode chamber frame 6 at a desired spacing. Cathodes 2 are connected electrically and mechanically to a cathode chamber frame 7 by means of leaf springs 5 of, for example, iron, steel, etc. and expand at a desired spacing on both sides in a free state. Both these electrodes are brought in contact substantially and respectively with a cation exchange membrane 3, whereby one unit of the electrolytic cell is assembled. At this time, the spacing between the cathodes 2 is made narrower than that in the state of free, and this puts both electrodes in contact with the membrane 3 under adequate contact pressure. Hence, the spacing between the electrodes is only the thickness of the membrane 3, and since the gases produced on the electrode surfaces escape from the rear of the electrodes, they are difficult to enter between both electrodes and the membrane 3.
