  • Patent number: 8336942
    Abstract: A guide structure for guiding a removable seat to move between a support base and a storage container is constituted by a joint portion between a lower face of a seat cushion of the seat and the support base and is constituted as a storing structure of the storage container. And, an arrangement relationship between both members is constituted to be such an arrangement relationship that the removable seat can also be guided to move to the guide structure constituted at the storage container in a state where the removable seat is guided to move by the guide structure constituted at the removable seat.

  • Patent number: 7857392
    Abstract: A vehicle seat can include a stopper capable of stopping a forward tilting of a seat back at a forwardly tilted position, and a stopper operation mechanism. The stopper operation mechanism has a main pivoting member that is pivoted through an operation of a forward tilting operation lever, a sub pivoting member that is pivoted with respect to the main pivoting member, and a connection spring connecting these tilting members to each other. When the forward tilting operation lever is operated, the sub pivoting member receives a force from the connection spring to be pivoted together with the main pivoting member, causing the stopper to move to an acting position. When the stopper is pushed from the acting position toward a non-acting position, with the forward tilting operation lever being operated, the sub pivoting member receives a force from the stopper to elastically deform the connection spring, and is pivoted with respect to the main pivoting member together with the stopper.

  • Patent number: 7649687
    Abstract: A reflective screen includes a light reflecting layer, and a light diffusing layer provided on the light reflecting layer. The light diffusing layer has the diffusion property that in one (A axis) of two perpendicular axial directions on a light diffusion plane, a luminance distribution curve versus incidence angle is asymmetric with respect to the zero-incidence-angle axis, and the side on which the incidence angle (half-luminance incidence angle) with half of a peak luminance on the A axis in the normal direction to the screen plane is small faces in a direction in which external light has the highest strength.

  • Patent number: 5538678
    Abstract: In order to produce a cassette, such as tape cassette, disc cassette or the like, the following steps are taken. First, fixed and movable dies are prepared which are unitable to define therewithin a shaped cavity. The movable die has at its inner surface a retaining ridge which includes a first portion immediately projected from the inner surface and a second portion immediately projected from the first portion. The second portion has side walls at least one of which has a laterally extending projection at the position remote from the first portion. Second, the fixed and movable dies are coupled to define the shaped cavity therewithin. Third, a plastic material is injected into the shaped cavity in such a manner that the retaining ridge is immersed in the injected plastic material. Fourth, the fixed and movable dies are uncoupled and a cured molded article of the plastic material thus produced is released from the movable die.
