Abstract: PURPOSE:To execute the switch of a diversity reception condition and a non- diversity reception condition only with the attaching/detaching of a sub antenna terminal to/from a sub antenna input terminal by providing a changing-over switch, which has a movable contact, and a switching device, etc. CONSTITUTION:When a terminal 20 of a sub antenna is not inserted to a sub antenna input terminal 12, a lever 15 of a changing-over switch 14, which is interlocked with the attaching/detaching of the terminal 20, is depressed and a movable contact 16 is connected with a fixed terminal 17. Thus, a switching transistor TRQ1 goes to a conductive condition and through a diode 1, in the internal part of a switching device 13, the antenna is forcibly fixed to a main antenna side. Then, the non-diversity reception condition is obtained. On the other hand, when the terminal 20 is inserted to the terminal 12, the lever 15 is depressed and the contact 16 is connected with a fixed terminal 18. Then, the TRQ1 goes to a non-conductive condition and through the diode D1, in the internal part of the device 13, the forcible fixing to the main antenna side is released. Then, the diversity reception condition is obtained. Accordingly, the switch of the reception condition can be executed only by the attaching/ detaching of the terminal 20 to/from the terminal 21.

Title: Car-height adjuster
Inventor: OOHASHI KAORU
IPC: B60G3/02
Filed: 1983-10-14
Abstract: PURPOSE:To prevent overshoot and undershoot by controlling the car-height speed so as to be high when the difference between a detected car-height and an amid car-height is larger than a prescribed value and low when the difference is smaller. CONSTITUTION:Each detected car-height signal of car-height sensors 40A-40C is input into a control circuit 60. Said control circuit 60 determines an aimed car-height and calculates the difference between the aimed car-height and a detected car-height by the aid of the operation signal of a manual switch 70 and according to a prescribed program, and compares said difference value with a set difference value. When the calculated difference value is larger than the set difference value, car-height adjustment is performed speedily by putting solenoids 23A-23C or solenoids 32A-32C into continuous electric conduction with a duty ratio of 100%. When the difference is smaller than the set value, the car-height adjusting speed is reduced by transmitting intermittent signals with a duty ratio T2/T1 into the solenoids 23A-23C and 32A-32C. Thus, overshoot and undershoot can be prevented.

Title: Ceramic-metal composite material and method of binding said material to metal structure
Inventor: SHIYUTEFUAN SHINTORAA
IPC: C04B41/88
Filed: 1990-07-23
Abstract: To date, highly porous ceramic materials have been infiltrated with a metal melt so that the product produced therefrom has a predominantly metallic structure. This ceramic-metal composite (CMC) is substantially metal-like in its properties, so that the requirements with regard to hardness, heat stability and wear are well below the values of the purely ceramic materials. The properties of the ceramic materials with regard to flexural strength, toughness, modulus of elasticity, hardness and resistance to wear are to be improved while retaining or increasing the properties such as hardness, temperature behaviour and resistance to wear, which are superior compared with metallic materials. The metal-ceramic composite is characterised in that the ceramic is composed of several layers, the layer thickness being between 10 and 150  mu m and the mean pore radius between 100 and 1000 nm with a final open porosity of 5-14% and a total porosity of 5-30%, and the metal fills the pore volume except for a residual pore volume of 0.1 to 10%, based on the initial porosity. The ceramic-metal composite is preferably used for binding to metal structures, such as welded or soldered ceramic/metal constructions.
