Abstract: A thin-walled laminated synthetic resin body for a liquid container according to the invention comprises first and second thin-walled synthetic resin layers (10, 20), each having a curved surface portion (11, 21) and a projection (12, 22) extending outwardly from a predetermined region at an edge of the curved surface portion (11, 21). The first and second layers (10, 20) are laminated to each other with the curved surface portions (11, 21) bulging out in the same direction, are integrated with each other at the edges (13, 23) of the curved surface portions (11, 21) and projections (12, 22), and are separable from each other at regions exclusive of the edges (13, 23). When a liquid is charged, the curved surface portion (21) of one of the first and second layers (20) is separated from the curved surface portion (11) of the other layer (10) and reversed.

Abstract: When a rear seat is moved forward, a front leg is swung forward around a roller arm. When the front leg of the rear seat is swung forward by a predetermined angle, a hook provided in the roller arm is detached from a round bar portion of a striker so that a roller is moved downward along a guide rail. Further, as the roller is moved downward along the guide rail, the front leg of the rear seat is swung forward around the roller arm. Therefore, a radius of rotation of the seat is reduced when the rear seat is moved to a position for storage on a vertical-front-side floor surface.

Abstract: A unit detachably attachable to a main body of an image forming apparatus includes developing means for developing a latent image born on an image bearing body and storage means for storing a time which has elapsed from a last developing operation of the developing means.

Abstract: A simple-structure vehicular rear seat wherein an upstanding seat cushion reliably receives and stops a luggage piece placed on a luggage supportive floor surface if the piece moves for any reason. When a seat back is laid down forward, the reverse surface of the seat back can be used as a luggage supportive floor surface. A seat cushion is supported on an elevated step portion of a stepped floor, and made up of a lower cushion and an upper cushion. The upper cushion is connected to the elevated step portion by a link-type connection mechanism that allows the upper cushion to be moved between a normal position where the upper cushion is supported on the lower cushion and an upstanding position where the reverse surface of the upper cushion abuts against and is supported by a front wall surface of the elevated step portion.

Abstract: A rear seat apparatus for a vehicle which is provided on a floor surface where a recess is formed includes: a lower seat cushion portion located in the recess; and an upper seat cushion portion having a seating surface, wherein the lower seat cushion portion and the upper seat cushion portion are provided in such a manner as to be separable.

Abstract: A rear seat apparatus for a vehicle is disposed on a rear elevated portion of a stepped floor of the vehicle. At least a rear seat cushion of the rear seat apparatus is allowed to swing toward the front of the vehicle from a horizontal seating state, in which a passenger may sit on the rear seat cushion. The rear seat apparatus has a connection mechanism for connecting the rear seat cushion to the rear elevated portion of the floor. The connection mechanism allows the rear seat cushion to be moved by approximately 90 degrees toward the front of the vehicle and then slid downward so as to be brought into an upright state, in which a front portion of the rear seat cushion is held on a front lower-level portion of the floor. The connection mechanism also allows the rear seat cushion to be moved by approximately 180 degrees from the seating state toward the front of the vehicle so as to be brought into an overturned state.

Abstract: A rear seat apparatus for a vehicle is disposed on a rear elevated portion of the floor of the vehicle and allows at least a rear seat cushion, which is a portion of the rear seat apparatus, to swing by approximately 90 degrees toward the front of the vehicle from a horizontal seating state to an upright state. The rear seat apparatus includes a connecting mechanism which connects the rear seat cushion to the floor so as to allow the rear seat cushion to be swung between the seating state and the upright state. In the seating state, the rear seat cushion is disposed on the floor so that a passenger can sit thereon. In the upright state, the rear surface of the rear seat cushion is allowed to abut the vertical wall surface of a stepped portion of the floor.

Abstract: A vehicle rear seat device, which enables an increase in a floor surface area of a rear portion of a vehicle, includes: a seat cushion provided so as to be rotatable approximately 180 degrees toward a front of the vehicle; a seat back which is forwardly-collapsible; and a rotating mechanism which rotates the seat cushion and at which a center of rotation of the seat cushion is set at a height which is approximately one-half of a height of the seat cushion at a front end surface of the seat cushion.

Abstract: A mounting structure for mounting a polygon mirror on a rotating body includes a mirror seat formed in the rotating body for mounting the polygon mirror thereon and a fixing device for fixing the polygon mirror on the mirror seat. The mirror seat is formed on the periphery of the rotating body, and the polygon mirror includes in a top surface thereof an annular groove of a rectangular section at a position thereof a predetermined radius from the center of rotation of the rotating body. The fixing device comprises a planar ring-shaped anchoring member fixed to the rotating body and having along a peripheral portion thereof a plurality of downwardly extending conical or semispherical projections. The projections of the anchoring member engage with the annular groove in the polygon mirror and press against the upper edge of the inner periphery of the groove by point contact to thereby fix the polygon mirror in position.

Abstract: A rear seat device for a vehicle disposed on a higher, rear section of a stepped floor surface of a vehicle, and provided so as to be rotatable by substantially 180 degrees toward a front of the vehicle, including: a rear seat back whose length is adjustable between a seating state length, which is a length of the rear seat back in an ordinary seating state for a vehicle occupant, and a folded-up state length, which is shorter than the seating state length.

Abstract: Herein disclosed is a liquid injection container which comprises: a container body 1; a cylinder 10 depending into the container body from a cap-shaped member 3 fitted on the outer face of the mouth/neck portion of the container body; and an actuator 20 having a stem 17 erected through the top wail 4 of the cap-shaped member from a cylindrical piston 16, which is fitted in the cylinder, and a head 18 fitted on the upper end of the stem and having a nozzle opened forward. The actuator is moved up and down with respect to the cylinder for sucking a liquid in the container body into the cylinder and discharging the liquid in the cylinder out of the nozzle 19 through the stem. A finger knob 80 attached to the top face of the head for receiving a finger. The vertical movements of the actuator are accomplished by the tip of the finger inserted into the finger knob. The actuations of the actuator are facilitated through use of auxiliary walls 6 and 6 acting as a finger knob and guiding the head.
