摘要:
In a flash device having the body part thereof arranged to be turnable relative to a fixed or stationary part which includes a mounting part for mounting the flash device on a camera so that the body part can be uplifted when the flash device is to be used and can be bent down toward the lens barrel of the camera for improved portability when the flash device is not in use, an operation member is disposed on the fixed part in such a position as to be covered by the body part when the body part is shifted to a usable position or to an unusable position thereof so that water, etc. can be prevented from entering the inside of the flash device via the operation member while the flash device is used or not used in the rain.

摘要:
An elastomeric shock and vibration isolator having a ring shaped rubber member in which a space is formed or a ring shaped rubber member having within such an internal space a sealed gas chamber and two liquid chambers filled with liquid which are interconnected through an orifice has a tightening ring on the outer circumference of the ring shaped member. The tightening ring is adjustable to adjust the tightening force against the ring shaped rubber member. The characteristics of a thus constructed elastomeric shock and vibration isolator can be changed to correspond to the position and condition of utilization.
摘要:
A recording light beam from an argon laser is modulated with an electrical recording signal and then recorded on a rotating disc-shaped record medium. Immediately after this recording, a recorded signal on the record medium is reproduced with a light beam from a helium-argon laser and converted into an electrical signal. Duty cycles of both signals are sensed by respective duty cycle sensors. A differential amplifier produces a differential signal between the sensed duty cycles and supplies it to an optical modulator arranged to control the output of the recording laser. The modulator controls the recording light beam to its optimum light level for recording in response to the differential signal which was detected just before its modulation.
摘要:
A recording optical system forms a recording spot to record a pitted signal on a record surface. A first reproducing optical system forms a reproducing spot fixed with respect to the recording spot on the record surface for monitoring purposes, and a second reproducing optical system with the greater part of the optical components thereof common to the first reproducing optical system and also including a rotatable reflecting mirror for forming a tracking spot on the record surface. The tracking spot is movable on the recorded signal by the rotation of the mirror in response to the light reflected from the record surface for causing the tracking spot to accurately track the pitted signal on the record surface.

The purpose of the present invention is to provide a gasket material that is capable of preventing corrosion caused by sulfur element, can be used as a seal part for a product that is easily damaged by corrosion, such as an electronic part, and is capable of forming a tight seal under low surface pressure with a material having low rigidity and inadequate reliability such as to have a blowhole, and that can prevent reduction in bolt axial load without producing plastic flow (setting) under pressure. The purpose is achieved by a gasket material in which a foamed rubber layer having a closed cell structure is formed, via an adhesive layer, on at least one side of a metal plate, wherein the foamed rubber layer comprises a carboxyl group-modified nitrile rubber, the expansion ratio of the foamed rubber layer is 2.0 to 3.0, and the foamed rubber layer is crosslinked with an epoxy compound.
摘要:
A fixing device includes a temperature measuring unit, configured to measure the temperature in regions that extend partially along the outer surface of a heating rotating body, which includes a resistance heating layer, in the circumferential direction and are aligned in the direction of the axis of rotation of the heat rotating body, and a control unit configured to sample temperatures, measured by the temperature measuring unit in each of the regions, over the entire outer surface of the heating rotating body in the circumferential direction by causing the heating rotating body to rotate while supplying a predetermined amount of power to the resistance heating layer, and to determine whether an abnormality has occurred in the resistance heating layer based on the difference between the maximum temperature and the minimum temperature among the sampled temperatures in each region.

The opposite side of a connecting intermediate section 32A of a diaphragm 32 to that of a first end section 32B extends from the connecting intermediate section 32A as a second end section 32C side that folds back towards the tube outside in an inside out reversed state. The diameter of the second end portion 32C is set larger than the diameter of the connecting intermediate section 32A. The second end portion 32C is fitted over an end on a chamber member 22 side of an outer tube member 60 and fixed with press contact against the outer tube member 60 by a band 72.
