Abstract: A piezoelectric power generating device that includes a piezoelectric element having a first surface and a second surface opposite the first surface, a stopper, and a lever. The stopper has a first contact surface that is in contact with the first surface. The lever includes a contact portion, which includes a second contact surface that is in contact with the second surface, and a displacement portion. The lever is arranged in such a manner as to be rotatable relative to the stopper around a rotation axis such that the second contact surface presses the second surface when the displacement portion rotates relative to the stopper around the rotation axis.

Abstract: A method of producing a piezoeIectric resonator includes the steps of forming first to third internal electrodes by printing an electrically conductive paste onto a green sheet, punching out portions of the green sheet having the first to third internal electrodes formed thereon, so that at least three types of green sheets are punched out with a location of the internal electrode serving as a reference location, in which the first sheet is punched out by shifting a punching location by a first shift amount in a first direction with respect to the reference location, the second sheet is punched out by shifting a punching location by the first shift amount in a direction opposite to the first direction, and the third sheet is punched out at the reference location, forming a layered body by stacking the punched out green sheets, and forming a unit by cutting the layered body.

Abstract: A method of producing a multilayer piezoelectric resonator includes the steps of forming first to third internal electrodes by printing an electrically conductive paste with a certain shape onto a surface of a green sheet formed of piezoelectric ceramic, punching out portions of the green sheet having the first to third internal electrodes formed thereon, so that at least three types of green sheets including first to third green sheets, are punched out with a particular location of its corresponding internal electrode serving as a reference location, in which the first sheet is punched out by shifting a punching location by a first shift amount in a first direction with respect to the reference location, the second sheet is punched out by shifting a punching location by the first shift amount in a direction opposite to the first direction, and the third sheet is punched out at the reference position, forming a layered body by placing the punched out green sheets upon each other in a predetermined order, form

Abstract: A vehicular headlamp wherein aiming adjustment of two reflectors can be conducted accurately regardless of the positional relation between aiming screws operating in conjunction with each other. The headlamp includes first and second reflectors mounted in a lamp chamber defined by a lamp body opening at its front and a lens covering the front opening of the lamp body, the reflectors each being tiltable by turning of an aiming screw of a corresponding aiming mechanism that supports the corresponding reflector in a tiltable manner relative to the lamp body. A belt mechanism rotationally couples the two aiming screws for allowing the first aiming screw for tilting the first reflector and the second aiming screw for tilting the second reflector to be turned in conjunction with each other.

Abstract: An optical axis adjustment structure which includes an aiming adjustment screw having a ball part disposed at one end thereof for receiving and being supported by a movable part of a lamp or the like, an intermediate part screw-engaging with a nut member fitted in a stationary part of a vehicle body or the like, and an operating part disposed at the other end thereof for a rotational operation, and the outer dimension of the operating part of the aiming adjustment screw is designed to be larger than the threaded intermediate part of the screw and the outer diameter of the ball part is larger than the diameter of the threaded part of the screw, while the nut member is integrally molded with the aiming adjustment screw at the intermediate part thereof.

Abstract: A lamp using a discharge bulb as a light source in which the size thereof in axial directions is reduced. A discharge bulb incorporated in a lamp body is used as a light source. A lighting circuit for lighting the discharge bulb is accommodated in a case, and the case is integrated with the lamp body 1. The lighting circuit accommodating case, which is thin-structured, is arranged on the back side of a socket connector of the discharge bulb, and a circuit section constituting the lighting circuit is arranged in an outer circumferential region of the socket connector. Since the lighting circuit is arranged to the rear of the socket connector, it is not necessary to provide a space for arranging the lighting circuit, and therefore the lamp can be made thin. In addition, the discharge bulb can be mounted and removed through a space in the lighting circuit.

Abstract: An aimable vehicle headlamp is disclosed which has a lamp unit rigidly held by a mounting ring which is of rectangular, horizontally elongated shape as seen in a front view and which is to be mounted to a vehicle for rotary motion in every direction within limits. A helical tension spring is coupled to the mounting ring at a point adjacent one corner thereof for biasing the same toward the vehicle. A horizontal aiming screw extends between a first lug on one shorter side, away from the corner, of the mounting ring and the vehicle. A vertical aiming screw extends between a second lug on one longer side, also away from the corner, of the mounting ring and the vehicle. The second lug projects from the one longer side of the mounting ring a greater extent than does the first lug from the one shorter side of the mounting ring, so that approximately equal forces are required for turning the horizontal and vertical aiming screws.

Abstract: A vehicle headlamp including a lamp unit coupled to a lamp housing via horizontal and vertical aiming mechanisms each including an aiming screw. At least the horizontal aiming screw is coupled to the lamp unit via a socket seat of flexible material fastened to the back of the lamp unit. The socket seat flexibly carries a socket in which the ball on one end of the horizontal aiming screw is engaged. The flexible socket seat takes up torsional stresses that are exerted on the horizontal aiming screw while this screw is being tightened or loosened for horizontally aiming the headlamp.

Abstract: The present invention relates to an aiming device for adjusting the optical axis of an automobile head lamp, characterized in that it comprises a hollow bearing attached to a movable member which is a lamp unit or a reflection mirror to be moved for adjusting the optical axis, a gear case housing a worm gear and a spur gear engaged with each other, the gear case being attached to a fixed member which is an autobody or a housing for supporting said movable member, an aiming screw whose head is fitted into said hollow bearing and whose screw portion is screwed into a female threaded hole formed in the shaft center of said spur gear, and a device for inhibiting said aiming screw from rotating circumferentially.
