A chair provided with a backrest for use in offices, etc., comprising an inner shell (2) and an outer shell (3). Conventional chairs of this type have a problem that there is little freedom in design with respect to strength and flexibility since only the inner shell serves as a structural member. An object of this chair is to increase the freedom. To this end, in the chair of this invention, the outer shell (3) as well as the inner shell (2) are formed as an integral body L-shaped in side view and comprising a seat portion (31) and a backrest portion (32), so that a three-dimensional shell structure is formed. In this chair, various measures are taken to solve the problem caused by the outer shell which is formed into an integral body. First, a fixed shell (6) is adopted for preventing a gap from being formed. Also, to obtain a required resiliency the shells (2, 3) are of such a construction as to allow a positional shift between the shells, and the inner shell (2) is supported by two brackets (118, 119). In order not to make the user feel uneasy upon resilient deformation of the shells, they are so constructed that the brackrest point (d) can be suitably shifted. Moreover, to connect the shells properly claws, (302, 602) of a particular type and inclined bolts (355) are used. Also, to make a mechanism to be provided between the shells (2,3) as compact as possible, the balancing members (101) support a backrest support (104).

A chair with a backrest is arranged so that the seat can be shifted forwardly to a rest position upon a rearward inclination of the backrest. The front end of the seat is supported pivotably on a support base, and the seat is movable forwardly and rearwardly. A balancing member is provided below the seat, and the support base supports a fulcrum of the balancing member set between a front and rear point of action of the balancing member. A backrest is provided on the rear end of the balancing member, and a rear part of the seat is supported on the rear point of action of the balancing member through seat receiving means. An upward movement of the front point of action of the balancing member is translated by motion translating means to a forward movement of the seat.

A vehicle front body structure including a front end module attached to a body front end. The front end module includes a frame member and a headlamp unit supported on the frame member. The headlamp unit is provided with a mounting device which is configured to flexibly support the headlamp unit on the frame member, and to provide a tendency to move the headlamp unit to its attachment position, upon application of a force exceeding a predetermined threshold to the headlamp unit.

A curved panel including a panel body and a pair of reinforcing members fixed to the panel body and arranged so that a planar restorative force of the panel body is balanced by a resilient force of each of the pair of reinforcing members so as to keep the panel body at a predetermined curvature. The panel body is made of resiliently deformable material including a face portion at (a) each of a first pair of opposite sides to which a deformable bent portion is attached which allows the face portion of the panel body to be curved to the predetermined curvature and at (b) each of a second pair of opposite sides to which a reinforcing bent portion is attached which keeps the second pair of opposite sides linear. The reinforcing members have a curvature greater than the predetermined curvature and are fixed to the deformable bent portions of the panel body.

The desk comprises a top plate and legs which are assembled so as to be able to be disassembled. The desk requires a reduced number of parts to connect the top plate and the legs, so that the labor required for assembly and disassembly may be reduced. To this end the top plate has sufficient rigidity, and each of the legs is provided with an upwardly facing surface adapted to be brought into contact with the under surface of the top plate and at the top end thereof with an arm extending along the front edge of the top plate. The top plate and the legs are connected by tapered engaging means and claw-type engaging means. The tapered engaging means comprises a concavely tapered surface formed in the front edge of the top plate and a convexly tapered surface formed on the arm of each leg, so that the two surfaces are brought into close contact with each other by sliding the leg relative to the top plate toward the user's side. The claw-type engaging means comprises bent claws formed on the upper surface of each leg and claw-receiving holes formed in the under surface of the top plate, so that the claws may be brought into engagement in the holes by sliding the leg relative to the top plate toward the user's side. Upon engagement of the engaging means, the above-mentioned arm is securely fixed to the front edge of the top plate by a fastener.

A medical material comprising a high-molecular weight material and a heparin derivative is provided, which high-molecular weight material comprises a high-molecular weight compound having functional groups capable of binding with epoxy groups, a compound having at least two amino groups and a polymer having a number of epoxy groups, said functional groups and some of said amino groups being bound to said epoxy groups, and which heparin derivative comprises heparin and an epoxy compound having at least two epoxy groups part of which is bound to amino groups in the heparin, the amino groups not bound to the epoxy groups in said high-molecular weight material being bound to the epoxy groups not bound to the amino groups in the heparin derivative. Also provided are an intermediate (high-molecular weight material) to be used for said medical material, as well as processes for producing said medical material and said intermediate. This medical material retains the activity of heparin intact and has it bound strongly and in a large amount. Further, this medical material has good biocompatibility. The above-described intermediate and processes for production further enhance the characteristics of the above-described medical material.
摘要:
The present invention provides a three-piece rectangular can which can overcome drawbacks (joint defect) of a can body joint portion of a three-piece can, and is of a new type which overcomes shortage of a can body strength which a two-piece can possesses, and exhibits excellent liquid leakage resistance, excellent can body strength and excellent heat radiation property or the like even when the can is used as a casing of a battery or electric equipment. For this end, the three-piece rectangular can of the present invention is formed such that a circular blank formed of an aluminum plate which forms an organic film on at least one surface thereof is formed into a bottomed circular can by deep drawing such that the organic film forms an inner side of the can, a cylindrical sleeve having no seam on a side surface thereof is formed by cutting a can bottom of the bottomed circular can, a rectangular can body portion having no seam on a side surface thereof is formed by deforming the cylindrical sleeve into a rectangular shape, a necking formed portion is formed by applying necking forming to opening portions at both ends of the rectangular can body, and a top lid and a bottom lid are mounted on the opening portions at both ends of the rectangular can body by double seaming by way of an organic compound.
