Abstract:
A vibration electric power generator includes an iron core having a coil wound therearound, a magnet member relatively moved with respect to the iron core by vibrations caused during running of a bicycle; and a nonmagnetic member fixed to the iron core and being in close contact with the magnet member. A plurality of magnets are stacked such that identical poles face each other. Switching is realized, by the vibrations caused during the running of the bicycle, between a state in which a first protrusion of the iron core is attracted and brought into contact with a north pole magnetism collecting and permeative plate and a second protrusion of the iron core is attracted and brought into contact with a south pole magnetism collecting and permeative plate and a state in which the second protrusion is attracted and brought into contact with a north pole magnetism collecting and permeative plate and the first protrusion is attracted and brought into contact with a south pole magnetism collecting and permeative plate.
Abstract:
A taking lens of a camera includes first and second lens elements. A lens holding frame retains the first lens element on a lens base or a front surface of a shutter unit. In the lens holding frame, a holding frame body is disposed in front of the first lens element. Arm portions are formed to project from a periphery of the holding frame body, have a distance to the lens base when in a free state, are bent resiliently by a retention pin or screws, and are secured to the lens base. Thus, the first lens element is squeezed tightly between the lens base and the holding frame body.
Abstract:
A light emitting apparatus for a bicycle includes a pulse generator for generating pulses having a predetermined period and a predetermined duty cycle, a light emitter for emitting light when a voltage is applied, and a voltage applying apparatus for applying a voltage to the light emitting apparatus in response to the generated pulses, and the pulse generator generates pulses which allows the light emitted from the light emitter to be visually recognized as light continuously emitted, by a person. Namely, the voltage is applied intermittently to the light emitter, such that the light emission by the light emitter can be visually recognized as light continuously emitted. Therefore, by the light emitting apparatus for the bicycle, brighter light can be emitted and power consumption by the circuit as a whole can be reduced, as compared with the prior art.
Abstract:
A battery case accommodating a battery is inserted into a battery case housing of a head lamp body. As the battery case is inserted, one protrusion of a stopper held by a stopper holding portion of the housing moves downward through an opening. When accommodation of the battery case is completed, another protrusion of the stopper as well as the one protrusion returns upward, and the former protrusion is fitted in a recess of the battery case to prevent movement of the battery case. When the head lamp body is attached to a bracket fixed on a bicycle in that state, a protrusion of the bracket prevents movement of the one protrusion of the stopper.
Abstract:
A starting clutch includes a planetary mechanism; a first clutch for outputting a torque to an outer diameter portion of the planetary mechanism; a second clutch for outputting the torque to an intermediate portion of the planetary mechanism; and a lock mechanism for locking a reactive force from an inner diameter portion of the planetary mechanism.
Abstract:
A headlight allowing easy adjustment of a delicate light distribution pattern during manufacturing is provided. The headlight includes a light source, a reflector surrounding the light source from its backside to reflect light incident from the light source frontward, and a front lens located in front of the light source and the reflector. The front lens is provided with at least two portions different in light transmission characteristic from each other.
Abstract:
A one-way clutch comprises an outer race where inner surface is formed with a raceway surface and an annular groove; an inner race whose outer surface is formed with a raceway surface; a plurality of wedge members interposed between the outer and inner races about the annular space defined therebetween; and a retainer comprising an outwardly extended annular projected portion engageable with the annular groove and a pushing member for causing the annular projected portion to elastically press against the annular groove. The retainer member is interposed between the outer and inner races so as to retain the plurality of wedge members, the outer race is provided with a stopper for limiting the displacement of the projected portion after the engagement thereof with the annular grove. The outer diameter of the projected portion is greater than the inner diameter of the raceway surface of the outer race.
Abstract:
A camera having a viewfinder and a taking lens changeable in focal length between at least two different focal lengths: a relatively short focal length suitable for wide-angle photography and a relatively long focal length suitable for telephotography and that allows close-up photography when the taking lens is changed to have the long focal length. The viewfinder has at least one movable lens which is axially moved and shifted away from the optical axis of the finder with respect to the axis of the taking lens when the taking lens is changed in focal length, to deflect the optical axis of the finder in order to cancel parallax error, depending on object distance.
Abstract:
A headlight reduced in size and ensuring sufficiently high efficiency is provided. The headlight includes a light source, a cylindrical condenser lens surrounding the light source from its periphery to transmit light incident from the light source, and a reflector surrounding the light source and the cylindrical condenser lens from their backsides to reflect the light transmitted through the cylindrical condenser lens frontward.
Abstract:
The present invention provides a starting clutch in which an input side element and an output side element are joined together by applying an axial load thereby to transmit a power, which clutch comprises an urging device for always providing the axial load, and a releasing device for releasing the input side element and the output side element from the axial load.
