摘要:
A vane compressor including plural vanes that perform a compression operation such that the normal to a circular arc formed by each vane tip portion and the normal to the inner peripheral surface of a cylinder are constantly approximately coincident with each other. Each of the plural vanes is held constantly in the normal direction of the inner peripheral surface of the cylinder or is held constantly along a direction having a fixed inclination with respect to the normal direction of the inner peripheral surface of the cylinder so that the compression operation is performed in the state the normal to the circular arc formed by the tip portion of each of the plural vanes and the normal to the inner peripheral surface of the cylinder are constantly approximately coincident with each other. The plural vanes are rotatably and movably supported with respect to a rotor portion.

A gap between a vane tip and a cylinder inner circumferential surface is denoted by δ. If rv is set as in an Expression (1), a first vane rotates with the vane tip thereof being out of contact with the cylinder inner circumferential surface. In the vane compressor, wear at the tip of a vane is suppressed, loss due to sliding on bearings is reduced by supporting a rotating shaft portion with a small diameter, and accuracy in an outside diameter and center of rotation of a rotor portion is increased.

A skin adhesion apparatus includes an upper mold half and a lower mold half. The upper mold half and the lower mold half clamps a core material and a skin laid on the core material so that the skin is adhered to a surface of the core material. Disposed along a mold surface of the upper mold half is a tubular member made of elastic material. The skin adhesion apparatus also includes a pump for supplying fluid into the tubular member. When adhering the skin to the core material, the upper mold half is pulled down and then stopped at a predetermined distance above the core material. After then, fluid is supplied into the tubular member so that the fluid pressure inflates the tubular member.

A plate-like support (2) is provided with a number of accommodating spaces (7) arranged along its surfaces. Two sets of spiral wires (4) are arranged perpendicular to each other, thereby forming a mesh member (5). This mesh member (5) forms the plate-like support (2) having a first surface (2a) and a second surface (2b) between which framework members (6) are disposed. These framework members (6) partition the accommodating spaces (7) so as to envelop them. The accommodating spaces (7) are formed over a space between the first surface (2a) and the second surface (2b), each of which is provided with openings (8), and adjoin the adjacent accommodating spaces (7) through the framework members (6). The framework members (6) are opened to provide communication portions (10), through which the adjacent accommodating spaces (7, 7) communicate with each other.

A system is provided to recover unutilized energy as electric power in hydraulic turbine power generation. The system includes a heat storage tank, a pump for pumping water from the heat storage tank and to air conditioning loads, a first water feed pipe connected between an outlet of the storage pump and the air conditioning loads, and a second water feed pipe for returning the water discharged from the air-conditioning loads. A hydraulic turbine driven generator is provided on a lower portion of the second water feed pipe at such a position as to recover the potential energy of the water discharged from the air conditioning loads.
摘要:
A fuel cell system and method of removing impurities from a catalyst are provided. The fuel cell system comprises a fuel cell stack comprising a pair of end plates and at least one unit cell. The unit cell contains a gas diffusion layer in contact with a membrane electrode assembly which is constructed of a polymer electrolyte membrane enclosed between two electrodes. The at least one unit cell is stacked between the end plates. The fuel cell system further comprises a voltage supply means and a means of impressing a cyclically varying voltage from the voltage supply means on the fuel cell stack. The cyclically varying voltage removes impurities that adhere to catalysts on the electrode surfaces in the fuel cell stack.
