摘要:
An electrode material capable of making more satisfactory the dispersion at the time of production and the aging property of a resonator than Au and capable of reducing the price as compared to Au. An resonator electrode material including a ternary alloy composed of Au and two metals M1 and M2, and being used as an excitation electrode to excite oscillation in a piezoelectric element, wherein the two metals M1 and M2 are, respectively, (a) metal M1: a metal exhibiting a tendency to decrease the temporal frequency property (Δf1/f1) from the reference value f1, and (b) metal M2: a metal exhibiting a tendency to increase the temporal frequency property (Δf1/f1) from the reference value f1. The metal M1 is preferably at least any one of Ag, Al and Ni, and the metal M2 is preferably at least any one of Pd, Ru, Pt, Ir, Rh and Cu.

An emitted-radio-wave shield capable of preventing the leakage of emitted radio waves from a circuit board includes a shield box, which houses the circuit board, and a shield plate that is easy to attach and remove in order to access the circuit board. A shield member, which is disposed at a joint between the shield box and the shield plate and is electrically connected with the shield box, shields emitted radio waves from the circuit board in a state in which the shield plate is secured to the shield box. The shield plate is formed to have a plurality of protrusions, which project toward the shield member, at a part thereof that contacts the shield member.

There is provided an image reading apparatus for acquiring a read signal of an image by receiving and photoelectrically converting a light reflected from a document. The location of an alien substance on an original plate is detected based on a reflected light received by a light receiving unit adapted to receive a light reflected from a document. When an alien substance is detected, an illumination unit selectively illuminates the location in which the alien substance has been detected. Also, a message which prompts cleaning of the alien substance is displayed. A method of displaying the alien substance location are also provided. Thereby, the image reading apparatus of the present invention can assists a user in cleaning the alien substance such as a dust or dirt on the original plate.

摘要:
An exposure device with a shutter operating in such a manner that the size of aperture opening defined by the shutter blades first increases from zero and then starts to decrease in predetermined timing, comprises a mechanism for opening the shutter with the help of an electric motor, while charging a spring as the drive source for closing movement of the shutter, an electromagnet arranged upon current supply to change the driving of the shutter from the opening mechanism to the spring, and a control circuit for controlling the operation of the shutter in such a manner that when taking one picture, the shutter blades reciprocate two times continuously to recycle substantially twice the exposure operation, as the operation of each of the motor and the electromagnet is recycled twice.
