摘要:
A work hardening treatment which decreases the Young's modulus, and an age hardening treatment which recovers or increases the Young's modulus decreased by the work hardening treatment are performed to form a vibrating portion, thereby attaining a vibrating element advantageous in downsizing while ensuring desired fatigue characteristics and vibration characteristics. This downsizes, for example, an actuator device, an optical scanning device, a video projection apparatus, and an image forming apparatus.

The oscillation element according to the present invention includes a torsion bar mounted on a base, and an oscillating member having a light reflection surface for reflecting light from a light source, which is fixed on the torsion bar protruding from the base. The oscillating member oscillates about a longitudinal axis of the torsion bar with an elastic deformation of the torsion bar, thereby deflecting the light that reflects at the light reflection surface in a direction intersecting the longitudinal axis. The oscillating member has two plates that are joined together so as to sandwich the torsion bar. On joining surfaces of the plates are provided with grooves for receiving the torsion bar, respectively. The plates have a symmetrical shape that the longitudinal axis serves as the axis of symmetry.

In an electrical connector for connecting connection objects to each other in a connecting direction, a holding member has an accommodating portion between a first and a second surface to which the connection objects are opposed, respectively, when connected to said electrical connector. A connecting member has elasticity and is placed in the accommodating portion. The holding member includes a first and a second wall which define the accommodating portion therebetween. At least one of the first and the second walls includes a restraining portion defining a space which allows a portion of the connecting member to elastically move in a predetermined direction crossing the connecting direction.

A connector capable of positively bringing terminals of connected objects into contact with associated portions of conductive films. The conductive films are formed in a film, for electrically connecting pads of two objects to be connected which are arranged on opposite sides of an elastic body. The film on which the conductive films are formed are bonded to the elastic body. A slit is formed in each of contact portions of the conductive films which are brought into contact with the pads of the objects to be connected so as to divide each contact portion into a plurality of parts such that the parts are independently displaceable.

In a magnetic connector acquiring connection with a mating connector by magnetic force, a base member has a particular surface to be faced to the mating connector upon connection. An electrode terminal is fixed to the base member and adapted to be electrically connected to the mating connector. The base member has a magnetic force generating portion having a plurality of magnetic poles for producing the magnetic force. N and the S poles of the magnetic poles are alternately arranged along the particular surface in a predetermined direction. Thus, the connector is properly positioned relative to the mating connector by the magnetic force.

An evaporative emission control system provided with a vapor-liquid separation chamber in which a liquefaction accelerating agent is filled for forcibly liquefying and separating the high boiling ingredient contained in evaporative emission and vaporizing the liquid fuel effectively when the evaporative emission is purged, thereby lightening the burden imposed on the adsorbents and preventing the deterioration of the adsorbents so as to make the canister small while keeping the adsorbent properties. It comprises a vapor-liquid separation chamber formed in the canister, a liquefaction accelerating agent which is fibrous or long strip-shaped and filled in the upper portion of the vapor-liquid separation chamber, a fuel storage chamber disposed at the lower portion of the vapor-liquid separation chamber for storing the separated liquid fuel and an adsorbent accommodating chamber which communicates with the vapor-liquid separation chamber.

A blade of an exposure control such as an iris control device or a shutter control device is provided for use in cameras. A sheet of a resin or metallic material configured as desired into the final blade form is placed in an injection molding machine which has a pin-forming cavity on one side of the sheet. The sheet is broken and penetrated at its portions where pins are to be formed and fixed, such that portions of the material of the sheet are deformed to project into the cavity. A molten resin is injected through a sprue formed on the opposite side of the sheet to the cavity so that the injected resin fills the cavity to form a pin in such a manner that the deformed and projected portion of the material of the sheet is embedded in the pin-forming resin. Another pin is formed on the other side of the sheet simultaneously with the first-mentioned pin in the same manner in the same die apparatus.

The present invention provides a connector configured to electrically connect two connection objects. The connector comprises an elastic member having a surface and a conductive film placed on the surface of the elastic member. The conductive film comprises two contact portions to be brought into contact with the connection objects, respectively, and a connect portion connecting the contact portions. Each of the contact portions comprises projections and a drainage arranged, at least in part, between the projections.
