Filed: 1992-06-02
Abstract: PURPOSE: To secure stability against vibration and mechanical and thermal stresses by bearing a hinge pin for joining members of a tentering frame chain in a sliding bushing made of a high-temperature resistant synthetic resin, and providing the sliding bushing with vertically slanting successive slits. CONSTITUTION: One face of a chain side plate is coupled to a support bushing 5 pushed thereto, and the other face comprises side plate lip members 3, 4 coupled with a hinge pin 6 which is held by a sliding bushing 7. The sliding bushing 7 is made of a high-temperature synthetic resin having friction-resistance and abrasion-resistance. As a consequence, a chain can be operated without at least lubrication in a region between the support bushing 5 and the hinge pin 6. An error prescribed by manufacture and caused by thermal or mechanical fastening is compensated by an oblique slit 14 formed in a circumferential surface of the sliding bushing 7.

Title: Elastic surface wave element
Inventor: EHATA YASUO
IPC: H03H9/02
Filed: 1977-11-29
Abstract: PURPOSE:To prevent the effect which is given to the temperature characteristics of the elastic surface wave element itself by mounting the element to the base of the case made of the material featuring an approximate expansion coefficient to the heat expansion coefficient of the substrate in the propagation direction of the surface wave. CONSTITUTION:The crystal of the 42.75 deg. revolution Y plate and X axis propagation direction is used for the surface wave propagation medium of the elastic surface wave element. In this case, the heat expansion coefficient is 13.7 ppm/ deg.C in the X axis direction. The heat expansion coefficient of the iron is 12 ppm/ deg.C which is approximate to that of the crystal. Thus, the increased mechanical strength and improved temperature characteristics of the element can be obtained when the element is mounted to the base of the iron-made case. The same effect is ensured by using the iron to the case base also in case the surface wave is propagated to the 112 deg. direction from the Y axis via the X-cut LiTaO3.

Abstract: PURPOSE:To detect quickly a trouble and to prevent the data loss by detecting the trouble produced at its own station to hold all communication circuits led out of its own station or some transmission lines under a space state and discontinuing the transmission of data given from other stations. CONSTITUTION:If a CPU power supply fault, for example, occurs, an alarm module 11 detects the fault and delivers a signal showing the generation of the fault to a signal output circuit 14. The circuit 14 uses said fault signal to deliver a signal to a circuit holding device 16 to stop the reception of data against all communication circuits 31-3n. Then the device 16 changes the transmission lines of all circuits 31-3n into a space state and holds them to give a request to the terminals 21-2n to stop the transmission of data. The terminals 21-2n detect that own reception lines (transmission lines of a computer system 10) are set under the space state and stops quickly the transmission of data in response to the transmission timing.
