An input apparatus includes a case, an operation body stored rotatably in the case, a magnetic body fixed to the operation body, a magnet provided around the operation body, a magnetic detection element for detecting a magnetic flux from the magnetic body, and a frame for retaining the case. The magnetic detection element faces the operation body with a predetermined space therebetween. The frame includes depression sections for causing the magnetic detection element to elastically contact the lower surface of the case. This input apparatus can accurately detect a rotation angle.

There is disclosed a member for use with an arm that is used as an automobile suspension arm, for example. The member comprises a rodlike body and bushing-mounting portions formed at both ends of the rodlike body. The rodlike body consists of a hollow tube fabricated by extruding an aluminum material into a circular cross section. The bushing-mounting portions are formed by welding bushing-mounting members to both ends of the rodlike body. Each bushing-mounting member has a hole in which a bushing is mounted with a press fit. The curved wall of the rodlike body is recessed at the longitudinal center of the rodlike body. When an automobile having the aforementioned member collides, an axial compressive load is applied to the rodlike body. The rodlike body buckles at the recessed portion. This mitigates the impact in the collision.

In a friction agitation joining method for joining metallic joining members, a joining device having a column-shaped rotor of a larger diameter and a pin-shaped probe of a smaller diameter integrally formed on an end of the rotor and protruded along an axis of the rotor is used for joining the metallic joining members. The probe is rotated and inserted into or around a butted portion of the joining members to soften a contact portion contacted by the probe by friction heat and to agitate the contact portion so that the joining members are butt joined. Each joining member has a thick portion at a butting side thereof The rotating rotor is contacted to the thick portions under pressure to soften the thick portions by friction heat so that a gap formed at the butted portion is filled with the materials of the softened thick portions.

A process for producing a vibration isolator includes the steps of preparing an axial member, an outside member, the outside member including a cylinder-shaped portion and a bracket having a hollow, and a cylinder-shaped rubber elastic member, and drawing the cylinder-shaped portion by inserting a stationary mold, with which a drawing apparatus is provided, into the hollow of the outside member so that an outer peripheral surface of the cylinder-shaped portion contacts with the stationary mold, by disposing the rubber elastic member and the axial member inside the cylinder-shaped portion, and by pressing the cylinder-shaped portion onto the stationary mold and simultaneously diametrically reducing the cylinder-shaped portion to plastically deform the same. The production process can obviate the conventional pressed-in construction in which metallic members contact with each other, can make the manufacture of the vibration isolator easy, and can reduce the manufacturing cost.

A method of controlling a regulating hole for regulating an amount of light, a flow rate of fluid, a pressure of fluid passing through a tubular passage is provided.A partition wall 5 formed by a viscoelastic solid containing magnetic particles is transversely disposed in the tubular passage 3 through which light or fluid passes. The partition wall 5 is provided with a regulating hole 6 for regulating an amount of the light, a flow rate of the fluid, or a pressure of the fluid so that the regulating hole 6 penetrates in an axial direction. Magnetic field gradient is generated the partition wall 5 in a radial direction in the tubular passage 3 to thereby change an opening degree of the regulating hole 6.
摘要:
A process for producing a vibration isolator. The process involves steps of forming an intermediate product including an axial member, an outside member having a cylinder-shaped portion and a rubber elastic member, and drawing the cylinder-shaped portion with a drawing apparatus provided with a drawing hole at least by pressing the cylinder-shaped portion into the drawing hole. The drawing hole has a predetermined dimensional diameter being smaller than an outer peripheral diameter of the cylinder-shaped portion. Thus, the cylinder-shaped portion is reduced diametrically to plastically deform. The production process can obviate the conventional pressed-in construction in which metallic members contact with each other, can make the manufacture of the vibration isolator easy, and can reduce the manufacturing cost.

An end holder (5) has a main recess (8) and cavities (8a) to fit on an end of an extruded aluminum profile material (1) having a semi-hollow portions (1a). Each of chucks (6) can protrude into the semi-hollow portion placed in the cavity (8a) so as to chuck the inner surface of said portion (1a), so that the end of material (1) can be firmly held in place while it is being severed from a body of the material to thereby produce high quality slices of an improved precision in dimension and shape.

A laser-emitting head (12) is placed in a cavity (6) of an aluminum hollow and profile material (3), the material being of a desired shape in cross section and having an inner peripheral wall. A laser beam of an energy level capable of cutting the material is irradiated from the cavity onto the inner peripheral wall while the head is being rotated along the wall in a circular direction. The hollow and profile material (3) can be sliced in this manner to produce knuckles (1) as one of automobile parts, even if it is of a comparatively large size adapted for production of larger knuckles.

A Rankine cycle system has a condenser, a refrigerant circulating pump connected to the condenser, a heat collecting device connected to the refrigerant circulating pump, and an expansion turbine connected to the heat collecting device and the condenser. The refrigerant circulating pump includes an expansion tank or pressure vessel, a refrigerant supply conduit connected to the lower part of the expansion tank and to the condenser, and a refrigerant discharge conduit connected to the upper part of the expansion tank. An open/close valve is installed in the refrigerant supply conduit. A pressure regulating valve installed in the refrigerant discharge pipe opens when a pressure reaches a specified value or higher. A temperature regulating device can heat the refrigerant in the expansion tank to produce a refrigerant vapor of saturated temperature or higher, which vapor can be introduced into the heat collecting device.
