A camera shutter has an automatic focusing lens operative when actuated to effect an automatic focusing operation. An actuating ring is normally placed in a non-operating region and momentarily shifted to an operating region during the automatic focusing operation. The actuating ring is sequentially displaceable in forward and reverse direction through the operating region to actuate the automatic focusing lens, and displaceable in the forward and reverse directions in the non-operating region without effecting actuation of the automatic focusing lens. A ratchet mechanism is coupled to the actuating ring for selectively locking and unlocking the actuating ring in the non-operating region in response to the displacement thereof in the forward and reverse directions. A bi-directionally rotatable stepping motor is connected to drive the actuating ring to displace the same in the forward and reverse directions.

A vehicular lamp comprising includes a light-emitting diode that is used as a light source and that emits light; and a light transmitting member that is arranged in a path of the emitted light and through which the light is passed. The light transmitting member shields the light-emitting diode from infrared rays that travel in an opposite direction to a traveling direction of the light.

In a vehicle ceiling structure, a long reinforcing rib is attached to a ceiling member of the vehicle, the rib being made of a resin having a different coefficient of thermal expansion from that of the ceiling member. The reinforcing rib comprises a plurality of segmented ribs that are divided by a gap in a longitudinal direction. One segmented rib of adjoining segmented ribs and is formed, in upper and lower parts of a front end portion thereof, with an upper protrusion and a lower protrusion protruding in the longitudinal direction. One segmented rib and the other segmented rib fit with each other such that a lower face of the upper protrusion and an upper face of the lower protrusion of the one segmented rib respectively face a rear end portion of the other segmented rib in an up and down direction.

A flat pre-board plate including connection electrodes, internal interconnections, and external-connection portions is prepared. This pre-board plate is cut at portions each located between adjacent ones of the connection electrodes, thereby forming trenches. A plurality of semiconductor elements are placed in each of the trenches. Electrode pads and the connection electrodes are connected to each other by metal wires. Transparent lids are placed on, and bonded to, spacers to cover the semiconductor elements. Thereafter, two lines of the connection electrodes arranged between adjacent ones of the trenches are separated from each other. Subsequently, adjacent ones of the semiconductor elements are also separated from each other.

A vehicular lamp unit including a flat-surfaced light source module and a projection lens that projects the image of light emitted from the light source module to the front as an inverted image. The light source module is comprised of a substrate and a light-emitting diode element disposed on the substrate and is formed therein with a subwavelength grating that reduces the reflection of light; and the formation density of the subwavelength grating is varied from position to position so as to vary the distribution of light emission intensity in the inverted image projected to the front.

There is provided an earpad that is attachable to a housing capable of containing an audio signal processing unit and includes a ring-shaped cushioning member and a covering member covering the ring-shaped cushioning member. In the earpad, the ring-shaped cushioning member includes an outer ring member, a middle ring member and an inner ring member, and the hardness of the middle ring member is different from the hardness of the outer ring member and the inner ring member.

A lamp unit including mirror member 18 having an upward reflecting surface 18a, which reflects part of reflected light from a reflector 16 upward and is disposed between the reflector 16 and a projection lens 12. The mirror member 18 can be moved in the direction of an optical axis Ax and can take a reference position, where the front end edge 18a1 of the upward reflecting surface 18a is located at the rear focal point F of the projection lens 12, and a front movement position, which is located forward a predetermined distance from the reference position. When the mirror member is moved to the front movement position, part of the reflected light from the reflector 16 passes through a space behind the mirror member 18 so as to be incident on the lower region of the projection lens 12.

A vehicular headlamp unit using a light-emitting element as a light source includes a projection lens arranged on an optical axis that extends in a vehicle longitudinal direction, and first and second light source units arranged rearward of the projection lens. The first light source unit includes a first light-emitting element arranged in a vicinity of the optical axis further rearward than a rear-side focal point of the projection lens, a first reflector arranged so as to cover the first light-emitting element from above and structured so as to reflect light from the first light-emitting element forward toward the optical axis, and a first mirror component having an upward-facing reflective surface that extends rearward generally along the optical axis from a vicinity of the rear-side focal point so as to reflect a portion of the reflected light from the first reflector upward. The second light source unit includes a second mirror component including a downward-facing reflective surface that extends diagonally downward toward a lamp rear side from a front end edge of the upward-facing reflective surface, a second light-emitting element arranged on the second mirror component facing forward and diagonally downward below the optical axis, a second reflector structured so as to reflect light from the second light-emitting element upward and generally converge such light at a region in a vicinity of the rear-side focal point on the downward-facing reflective surface, and a third reflector arranged downward of the second light-emitting element which reflects light from the second light-emitting element forward so that such light passes through a lower space of the projection lens.
