A chair-type massage machine is provided which comprises a seat, backrest and leg portion having a plurality of preset reclining angles for giving an effective massage to the user in various postures. The massage machine comprises a seat pivotally movably supported by a base, a backrest pivotally movably supported by the seat at the rear end thereof, a leg portion pivotally movably supported by the seat at the front end thereof, control means for controlling seat moving means, backrest moving means and the leg portion moving means and a manual controller. The control means has stored therein a plurality of preset reclining angles with respect to the angle of the seat, backrest and the leg portion. The manual controller has reclining selection buttons for selecting one of the reclining angles and an initial position button. The control means operates the moving means for the seat, backrest and leg portion when the reclining angle is selected by the reclining selection button and pivotally moves the seat, backrest and leg portion to the selected angle.

In the method of the invention for producing an electrode-membrane-frame assembly, its principal part is formed by laying a first catalyst layer onto one of surfaces of an electrolyte membrane, arranging a first gas diffusion layer onto the surface of the first catalyst layer and inside the circumferential region of the electrolyte membrane, laying a second catalyst layer onto the other surface of the electrolyte membrane, and arranging a second gas diffusion layer onto the surface of the second catalyst layer and inside the circumferential region of the electrolyte membrane so as to make the position of the outer circumference of the second gas diffusion layer different from that of the outer circumference of the first gas diffusion layer. Then, in the state that an outer circumferential portion of either the first gas diffusion layer or the second gas diffusion layer, the portion being positioned outside a region of the first and second gas diffusion layers wherein the two layers are opposed to each other, is opposed to a portion of a flat region located inside the frame of a frame-form primary molded body, the circumferential region of the principal part is arranged on the flat region, and subsequently a secondary molded body is formed to cover the circumferential region of the electrolyte membrane with the second molded body together with the primary molded body, in order to prevent the polymer electrolyte membrane from being broken or deformed.

A MEA-frame assembly is arranged in a mold for injection molding to form a first flow passage arranged so as to extend along the outer periphery of an electrode between the outer periphery of the electrode and the inner periphery of a frame, a second flow passage arranged so as to extend along an inner elastic member between the inner periphery and outer periphery of the frame and a plurality of connecting flow passages which communicate the first flow passage with the second flow passage. An elastic resin is injected into the first flow passage to fill the first flow passage with the elastic resin and to fill the second flow passage with the elastic resin through each of the communicating flow passages, thereby an elastic member which hermetically seals the space between the MEA-frame assembly and the separator is integrally formed.

First rubbing is performed on an entire surface of an alignment film (22) provided on a substrate (21), and then a mask part (51a) for masking a first region and a region of an alignment mark is formed on the alignment film (22) by using a resist layer (51). After performing second rubbing on the alignment film (22) through the mask part (51a), the mask part (51a) is removed, and a liquid crystal layer (23) is formed on the alignment film (22). In this way, the alignment mark is formed as a region having an optical function different from an optical function of a region surrounding the alignment mark.Thus, it is possible to produce a substrate (21) having an alignment mark formed without increasing processing steps at such a position as to contact the liquid crystal layer (23).

A fuel cell separator and a fuel cell are provided that can improve uniformity in reaction gas flow rate and can prevent flooding due to excessive condensed water in passage grooves appropriately. A reaction gas passage region (101) of a separator (2) has a flow splitting region (21) having a passage groove group where the reaction gas is split, and one or more flow merge regions (22) having a recessed portion in which the reaction gas is mixed and connecting a plurality of flow splitting regions so that the passage groove group of the adjacent flow splitting regions (21) are connected to the recessed portion, and protrusions (27) vertically extend from a bottom face of the recessed portion and arranged in an island form. A pair of passage groove groups connected to the recessed portion of the flow merge region (22) is formed so as to have a greater number of grooves in the upstream passage groove group than the number of grooves of grooves in the downstream passage groove group. The recessed portion of the flow merge region (22) is defined, in a turn portion of a serpentine shaped reaction gas passage region (101), by oblique boundaries between the recessed portion and a pair of passage groove groups which are connected to the recessed portion and by the outer end of the turn portion.
