摘要:
The sensitive coordinate input device of the present invention adopts a system in which the finger F of the operator is regarded as one electrode, and the electrostatic capacitance is varied depending on the changes in the distances between the finger and another electrode which is separated therefrom via a dielectric. Four electrodes are preferably disposed at regular angular positions. Among the four electrodes, two electrodes, and two electrodes which are located at opposite positions are spaced at intervals, respectively. Across the four electrodes, a sensitive member 15 is laid. The surface of the sensitive member is to be touched with the operator's finger F. The sensitive member is preferably formed by a dielectric having a high dielectric constant, such as a ceramic plate. According to the present invention, the area of sensitive area can easily be increased, and the determination of the cursor position on the screen of the CRT display apparatus can readily be performed.

In a control operation performed at the time of earthquake or strong wind, when a running elevator is stopped at the nearest floor, the natural frequency of the transverse vibration of a rope is prevented from resonating with the natural frequency of the building, and thereby the increase in transverse vibration of the rope is restrained.There is provided a rope resonance checking means in which, in the control operation in which when a shake of the building caused by earthquake or strong wind is detected, a running elevator is stopped at the nearest floor, or an elevator passing through an express zone is stopped emergently and runs at a low speed to the nearest floor, the natural frequency of the transverse vibration of the rope is compared with the natural frequency of the building, and selects the car stop position at a non-resonance position so as to prevent the natural frequency of the transverse vibration of the rope from resonating with the natural frequency of the building.

A battery connector in which, even when an engagement piece portion that is required for applying a preload to a contact of a contact member rubs with an engagement face formed in a wall face of a housing made of a synthetic resin, possibilities that the engagement face is shaved, and that the engagement piece portion is deformed can be eliminated. In the battery connector, a meandering contact member is housed in a housing. A mountain-like projection of the contact member is projected from an opening of the housing. An engagement piece portion formed in the mountain-like projection is engaged with an engagement face of the housing to apply a preload to the contact. The engagement piece portion has a shape which is free from an angular edge. Specifically, the engagement piece portion has a planar portion, and projection pieces which are continuously integrated with the planar portion through arcuate bent portions. Swollen portions having an arcuate face may be formed on the planar portion.

Method and apparatus for enabling fluid material contained in a package to be examined in a non-destructive manner to see whether there is any unacceptable alteration in the material. This examination is accomplished by shaking the package so that the package and its contents vibrate at the natural resonance frequency thereof, exposing the package to an irradiation of ultra-soft X-ray beams while the package is vibrating at the resonant frequency, either immediately after the package contents begin to be agitated by shaking or immediately after the vibration is stopped and it ceases to be agitated, detecting the strength of X-rays transmitted through the package and its contents, coverting the transmitted X-rays to a corresponding analog signal, and determining any alteration by comparing the analog signal against the refernece signal previously obtained in the same manner as described above for a like package with unaltered contents.
