Abstract: A main circuit portions are arranged in the order of a breaking section fixed-side conductor, a breaking section movable-side conductor, a disconnecting section movable-side conductor, and a disconnecting section fixed-side conductor, and first and second grounding conductors are respectively provided for grounding the breaking section fixed-side conductor and the disconnecting section fixed-side conductor at both end portions of the apparatus. The arrangement of operating devices is set in the order of a first grounding-section operating device, a breaking-section operating device, a disconnecting-section operating device, and a second grounding-section operating device. In addition, a breaking section is supported by a single supporting insulator to reduce the number of creepage insulation portions.

Abstract: A peep show toy and a peep show toy kit which are simple in construction, suitable for individual use, and capable of exhibiting a landscape, a portrait, a historical picture or a narrative, are disclosed, which include a hollow cube formed by at least one planar or curved wall. At least one observation hole is provided through which an observer can peep into the hollow cube. On the inner surface of the wall which comes in sight through the observation hole, a picture is drawn in perspective with a visual point disposed at the observation hole.

Abstract: An antivibration device for a clutch pedal in a clutch operating mechanism wherein upon depressing the clutch pedal a hydraulic pressure is caused in a master cylinder, which in turn actuates an operating cylinder to operate a withdrawal lever, the device having an oil damper provided in a hydraulic passage communicating between the master and operating cylinders, thereby absorbing fluctuations in hydraulic pressure in the operating cylinder caused by engine vibrations to prevent vibration of the clutch pedal.
