摘要:
An ultraviolet ray measuring apparatus is provided which comprises first and second photodiodes having substantially the same spectral sensitivity at least in an ultraviolet band, and a first optical filter arranged in front of a light-receiving face of the second photodiode, for shielding only light of at least a part of the ultraviolet band. The apparatus measures the light intensity and its accumulated value in accordance with the difference between electric signals output from the first and second photodiodes. It is preferable that a second optical filter, which has a main transmitting band in the ultraviolet band and a sub-transmitting band in the visible light range, be arranged in front of the light-receiving faces of the first and second photodiode. A multi-step bar graph display device displays indices, such as an MED multiple value and an SPF value, which represent the measured light intensity and accumulated value in association with a reference MED value, so that this apparatus can suitably serve as a sunburn monitor.

A zoom lens comprises in order from an object side, a first lens unit, a second lens unit, a third lens unit, a fourth lens unit, and a fifth lens unit having, respectively, a positive, negative, positive, negative, and positive refractive power. At the time of zooming from a wide angle end to a telephoto end, the first, third, and fourth lens units move toward the object side. A distance between the first and second lens units increase, a distance between the second and third lens units decrease, a distance between the third lens unit and the fourth lens unit changes, and a distance between the fourth lens unit and the fifth lens unit increases. The zoom lens satisfies the following expressions: 1.54

A magnetic circuit including a pole piece, a magnet, and a yoke is supported by using a suspension where outer and inner circumferential portions thereof are connected to each other with a supporting member, and the outer circumferential portion of the suspension is fixed to protrude from a housing or an inner wall of a cover provided with a stepped portion in a direction passing over the magnetic circuit toward an inner portion, so that it is possible to limit a movable range of the magnetic circuit by using the outer circumferential portion of the suspension and to prevent inner components of a main body of the multi-function vibration actuator from being destructed at the time of being impacted due to falling.

摘要:
A contact terminal which prevents a load from being concentrated on the contact terminal portion thereof when a part is disposed on a substrate, to prevent contact terminals from being short-circuited even if stacked, thereby reducing the overall space requirement. A projection is formed on a terminal base and the movable range of a contact is limited by the projection, whereby the load that is conventionally concentrated on a terminal support part can be distributed by a support part and the projection. Consequently, the durability of the terminal portion can be enhanced, the space for the contact terminal portion is saved, and a short circuit is prevented from occurring due to the contacting between the contact terminals.
摘要:
[Problems] To provide a multifunction vibration actuator which has flat rising and falling frequency characteristic at the time of generation of bodily sensation vibration and which is stable for an input signal.[Means for Solving Problems] Flat frequency characteristics can be obtained by using a two-fold rotational symmetry frame type suspension, and miniaturization of the whole multifunction vibration actuator can be made by the user of the frame type suspension. With regard to the frame type suspension, use of protruded configuration of corner parts ensures the effect of absorption of deflection of the suspension.
摘要:
There are comprised a first group lens G1 that has a negative refractive power at a fixed distance from an image plane, a second group lens G2 that has a positive refractive power, a third group lens G3 that has a positive refractive power, and a fourth group lens G4 that has a negative refractive power at a fixed distance from the image plane. The first group lens G1, the second group lens G2, the third group lens G3 and the fourth group lens G4 are arranged in order from the object side toward the image plane. Zooming is performed by moving the second group lens G2 and the third group lens G3 in the optical axis direction by lens-moving mechanisms 1, 2 so that a spacing between the first group lens G1 and the second group lens G2 at the telephoto end state is made smaller than a spacing between the first group lens G1 and the second group lens G2 at the wide angle end state, and a spacing between the third group lens G3 and the fourth group lens G4 increases as the zoom lens shifts from the wide angle end state to the telephoto end state.

In order to improve the reliability of an electrical connection between a power supply terminal of a vibrator and an electrode of a circuit board and to improve the efficiency of mounting the vibrator on the circuit board, the power supply terminal is made from a torsion coil spring and a contact portion of the power supply terminal in contact with the electrode of the circuit board is formed by winding. In addition, a torsion coil spring portion is wound around a spindle pin and a housing is provided with a step portion as a space for accommodating the contact portion without interference and a plane portion to which the contact portion faces. Moreover, a partition plate is provided between a pair of power supply terminals or a space where the contact portion can be elastically deformed is surrounded by a box member, a pair of power supply terminals having positive and negative polarities are extended in a bilaterally symmetric direction from torsion coil spring portions to the contact portions, and the power supply terminals are constructed so as to be elastically deformed to allow each contact portion to reach the outside of each torsion coil spring portion.
