Filed: 1998-07-23
Abstract: PROBLEM TO BE SOLVED: To reduce friction resistance between a tab and a positioning hole by forming a sliding contact part partially coming in contact with the flat outer surface of the tab in the inner circumference of the positioning hole of a connector. SOLUTION: A region corresponding to a flat outer surface 13A of a tab 13 out of the inner surfaces of a positioning hole 15 of a moving plate acts as a sliding contact part 15A projecting in a triangle shape to the tab 13 side. The sliding contact part 15A slidably comes in contact with only a part of the flat outer surface 13A at the tip. A tapered guiding slop is formed in the hole edge part on the tab 13 inserting side of the positioning hole 15. When the moving plate is moved according to the fitting operation of both connector housings, if the tab 13 is inclined in the right and left direction, the tip of the sliding contact part 15A comes in contact with the flat outer surface 13A on the inclined side of the tab 13. Friction resistance generating by sliding contact is made low, and fitting resistance of both connector housings is also made low.

Filed: 1988-08-23
Abstract: PURPOSE:To obtain a device capable of multiplexed storing operation and remarkably increasing the degree of integration by arranging a plurality of layers between a pair of electrodes, which layers have characteristics that switching is operated by electric field and switching voltages of which layers are different with each other. CONSTITUTION:Between a pair of electrodes, a plurality of layers are arranged. These layers have characteristics that switching is operated by electric field. Switching voltages of the layers are mutually different. For example, glass is used for a vapor deposition substrate; gold turning to electrodes is previously formed; a led phthalocyanine thin film is vapor-deposited and formed thereon. In order to make the resistance value cf each layer nearly equal, a first layer of the led phthalocyanine deposition film is formed in a thickness of about 18000Angstrom  at a deposition rate of 5Angstrom /sec, and a second layer of deposition film is formed in a thickness of about 20000Angstrom  at a deposition rate of 8Angstrom /sec. Hence, the first layer whose switching voltage is 4V, and the second layer whose switching voltage is 10V are obtained. After the two layers having different switching characteristics are formed in this manner, gold turning to facing electrodes are vapor deposited, and a sandwich type memory device is obtained.
