In a transmission power control circuit which performs power amplification of a transmission signal to one of several predetermined levels in response to a control signal and outputs the amplified signal, the bias voltage of the power amplifier circuit 1 is set to the optimum in response to the net level. Since the bias voltage is set to the optimum, the power loss in the power amplifier circuit i...

The object of the invention is centred on prefabricated construction or partial prefabrication, of buildings, using basic panels (1, 2) which are placed in pairs in a parallel manner at a certain distance between the two, in order to form the external structure of a certain building or construction. The said panels are used individually to form the internal walls. Each of the panels is of the type...

PURPOSE:To assure a molded high precision circuit board with high reliability by molding a plurality of resin products on one surface of a circuit film and combining them into an assembly. CONSTITUTION:A circuit film 22 inlcudes a flexible circuit pattern on one surface or on both surfaces of a heat-resistant insulating film by copper foil pattern etching or printing of a conductive paste. Two res...

PURPOSE:To prevent a leak of oil from a plug in a device where the breather plug is provided to an upper part of a case or the like forming a gear box, by forming upper and bottom two chambers in the bottom of an opening part in the gear box of said plug. CONSTITUTION:An air breather device 20 is constituted such that a screw hole 7 is formed to be internally and externally extended through the up...

PURPOSE:To prevent deformation of a conductor due to processing by punching off a rectangular conductor covered with insulation as it is without removal of terminal insulation, forming the conductor narrow, and defoliating with the sleeve to the insulation left. CONSTITUTION:A rectangular conductor 2 covered with insulation 1 as it is, undergoes punching process 3, and the width of the end of cond...

The invention relates to a process for treating organocyclosiloxane-containing mixtures with condensation catalysts. The resultant mixtures can be reacted with silanes or siloxanes to form organopolysiloxanes containing functional groups.

PURPOSE:To automatize a molding process and improve the efficiency for increasing the freedom of circuit design by forming lands being mechanical coupling means to keep the three-dimensional configuration of an FPC board through soldering and employing it also as connector means for the circuit. CONSTITUTION:An FPC board 1 is molded into the three-dimensional configuration as a cylindrical body. T...
