Title: Liquid crystal display element and information transmitting device using the same
Inventor: MORI SUNAO
IPC: G02F1/1339
Filed: 1994-03-15
Abstract: PURPOSE:To suppress generation of a defect according to a change of a cell gap by suppressing movement of liquid crystal molecules. CONSTITUTION:Since the surface of an orientation control film is provided with projecting parts 20,..., the moving directions of liquid crystals are reverse in the parts where these projecting parts 20,... are formed and the parts where, the projecting parts 20,... are not formed. Thus, the movement of the liquid crystals is suppressed with each other. The liquid crystal display element P is formed by spraying fine particulate adhesive resins in order to adhere substrates to each other and is so constituted that a cell gap fluctuates to some extent by setting the spraying density thereof coarse in the central part 65 of the element. Then, the cell gap of the central part 65 decreases even if the effect by the projecting parts 20 is not obtd. by a failure in temporarily setting the cell thickness at a desired value and even if the liquid crystals in the central part 65 move toward D1 or D2 and, therefore, the moving directions of the liquid crystal are inverted and the cell gap is eventually maintained nearly constant.

Title: Detection device for residual quantity of battery
Inventor: IKETANI KOHEI
IPC: G01R19/165
Filed: 1992-02-20
Abstract: PURPOSE:To detect the residual quantity of a battery accurately and easily. CONSTITUTION:An oscillator 13 outputs a square-wave signal having a definite cycle. Thereby, a constant-current switch 14 is turned on an off and gives a periodically changing load to a battery 12. An AC amplifier 15 amplifies only the change portion of a terminal voltage at the battery 12 and outputs it to a clamping circuit 16. The clamping circuit 16 clamps an output voltage from the AC amplifier 15 so as to be easily treated in a later-stage circuit. A peak detector 17 envelope-detects an output from the clamping circuit 16, and detects the magnitude of the change amplitude of the terminal voltage at the battery 12. When the magnitude of the change amplitude is larger than a prescribed value, a comparator 18 outputs a signal indicating that the residual quantity in the battery 12 has become smaller than a prescribed value.

Filed: 1984-04-10
Abstract: PURPOSE:To correct curl due to the heating of a fixing roller by composing a couple of rollers which discharge a form of heat pipes and cooling a heated form speedily through the heat pipes. CONSTITUTION:A paper discharge roller 8 is longer than a paper roller 9 and made of a heat pipe; and it contacts the roller 9 at the heat absorbing part 13 of the heat pie and a radiation part 14 never contacts the roller 9. When the heated form is discharged by paper discharge rollers 8 and 9, methyl alcohol vaporizes with the heat of the form at the heat absorbing part 13 of a wick 12, and the pressure of the methyl alcohol in the wick 12 at the heat absorbing part 13 drops owing to the vaporization, so that the methyl alcohol flows from right to left. The vaporizing methyl alcohol, on the other hand, moves from left to right and is condensed at the radiation part 14, and the heat absorbed at the heat absorbing part 13 is radiated. This operation is repeated and the heated form is cooled, so that its curl is corrected.
