Title: Piezoelectric type pressure sensor
Inventor: FUKADA TETSUJI
IPC: G01L23/10
Filed: 1986-10-28
Abstract: PURPOSE:To reduce the effect of heat, to enhance processing accuracy and to apply uniform force, by applying pressure by a pressure transmitting member so that shearing stress acts on both end surfaces of a cylindrical piezoelectric element. CONSTITUTION:A cylindrical piezoelectric element 3 has a pressure transmitting member 2 fixed to the inner peripheral part of the bottom surface thereof and is fixed to the central part of the pressure receiving surface 1' in a housing 1. A fixing member 4 is contacted with the outer peripheral part of the upper surface of the element 3 and a fixing screw member 7 is tightened to mount a heat insulating member 5 and a metal plate 6 to the housing 1 so as to fix both of them between the fixing member 4 and said screw member 17. Further, the member 5 avoids the direct conduction of heat from the housing 1 and attains the heat insulation of the element 3 not only from the electrodes on the inner and outer peripheral surfaces thereof but also from the housing 1 and the metal plate 6 generates the uniform load to the parts tightened by the member 7. Since the outer peripheral part of the end surface of the element 3 is fixed and pressure is applied to the inner peripheral part of the other end surface of the element 3 by the member, the stress in a shearing direction with respect to a polarizing axis direction acts on the element 3. Therefore, the effect of heat can be reduced by reducing the contact surface with the member 4 and processing accuracy can be enhanced.

Title: Double lock type electric connector
Inventor: KINOSHITA SHOJI
IPC: H01R13/42
Filed: 1990-09-28
Abstract: PURPOSE:To accurately detect insertion of a contact and increase the strength of an inserted pin by installing a common opening which crosses a plurality of contact accommodations on the side wall of an insulated housing to accommodate a double lock member in this opening. CONSTITUTION:A single large opening 40 for accommodating a double lock member 24 is formed across a plurality of contact accommodations on the side wall 38 of an insulated housing 22. That is, the insertion edges of the double lock member 24 are mutually interlocked, so that such flexibility as could be seen in the case of a conventional insertion pin can not be recognized. Accordingly, even if the insertion edges 46 abut against an imperfectly inserted contact, they never escape from the contact, so that it is impossible to make the double lock member 24 move to the substantial engagingly locking position; the imperfectly inserted contact can be accurately detected, therefore. It is thereby possible to accurately detect the imperfectly inserted contact and also sufficiently increase the engagingly locking strength of the contact.
