摘要:
A liquid crystal is sealed with a sealing member between first and second transparent substrates, whereby a liquid crystal cell capable of transmitting ultraviolet light is produced. The liquid crystal cell is inserted into a mould into which an ultraviolet-setting resin is dropped and which is used to produce a light control member. The ultraviolet-setting resin is pressed to be bonded to the liquid crystal cell. In this state, ultraviolet light is irradiated to the liquid crystal cell in the mould from outside the mould. Thus, the ultraviolet-setting resin is set while bonding to the liquid crystal cell. Thereafter, the liquid crystal cell is removed from the mould. Consequently, the light control member is directly formed on the liquid crystal cell.

The liquid crystal display device comprises a liquid crystal cell with liquid crystals sealed thereinbetween, sandwiched between two transparent substrates having an electrode on each of the inner surfaces thereof facing each other, a first reflective polarizing film disposed on the visible side of the liquid crystal cell, a second reflective polarizing film disposed on the side of the liquid crystal cell, opposite from the visible side, and a light absorption film disposed on the side of the second reflective polarizing film, opposite from the visible side. The first reflective polarizing film as well as the second reflective polarizing film is a polarizing sheet reflecting a light linearly polarized in the direction orthogonal to the transmission axis thereof. A light absorption film and/or a backlight may preferably be disposed under the second reflective polarizing film. Further, an absorption-type polarizing film or a light diffusion layer may preferably be disposed on the visible side of the first reflective polarizing film.

In order to perform a multi-gradation display of high quality on a liquid crystal panel (6) by a small-scale A/D converter (1), a 4 - bit A/D converter (1) is equipped with four reference potential couples for performing the dither method using arbitrary two reference potential couples in each of two fields to display a signal at a first pixel. Likewise the remaining two reference potential couples are used for the dither method to display the signal at a second pixel adjacent thereto. In this way, the dither method is applied to adjacent pixels using different reference potential couples to generate an area gradation, so that it is possible to represent 64 gradations owing to the multiple effect of the dither method and the dot area modulation method. Moreover, it is possible to obtain a display of high quality which is free from flicker disturbance since the dither cycle is 1/30 second.

According to the invention, a deodorant which comprises at least one of germanium, antimony and bismuth compounds is used for a permanent waving agent consisting mainly of a mercapto compound. The deodorant is utilized by being contained in the permanent waving agent, or applied as a pretreatment agent before the permanent waving operation is carried out.By use of the above-mentioned deodorant, the production of hydrogen sulfide of "unpleasant odor" can be restrained.

The amount of fuel supplied to a fuel cell is set to a second set value Qm2 smaller than a first set value Qm1 determined based on a load. Then, an output current Ifcr of the fuel cell with the fuel supply amount set to the second set value Qm2 is detected. The output current Ifcr is compared with a reference value Iref for determining mild deterioration to determine whether the fuel cell has deteriorated from the comparison result. If a determination that the fuel cell has deteriorated is made, the fuel supply amount is reset to a third set value Qm3 larger than the second set value Qm2.

A direct oxidation fuel cell system includes a fuel cell and a cooling device. An anode-side separator of the fuel cell has a fuel flow channel in the face in contact with the anode. The direction of a flow of air supplied by the cooling device is set so that the upstream-side portion in the average flow direction of fuel in the fuel flow channel is selectively cooled. This allows the upstream-side portion of the polymer electrolyte membrane having large MCO to be cooled, thereby reducing the amount of MCO. Also, the downstream-side portion where the fuel concentration in the fuel flow channel is low has a relatively high temperature, thereby making it possible to improve the energy conversion efficiency.

A separator used in a fuel cell stack includes an inlet chamber, a plurality of partition walls, and an outlet chamber. The partition walls are formed in the same length in an equal interval from the inlet chamber to the outlet chamber so as to form a plurality of linear passages. The outlet chamber is formed at an end side of the partition walls. The outlet chamber is provided with a first outlet and a second outlet opening in the facing edges of the separator. A space is provided between the center partition wall and the inner wall surface of the separator in the outlet chamber, and the first outlet and the second outlet communicate with each other via the space.
