Title: Amplifying circuit
Inventor: KOBAYASHI MASAHIKO
IPC: H03F1/22
Filed: 1990-01-29
Abstract: PURPOSE:To widen the band without decreasing the gain by injecting a prescribed bias current from the collector terminal of a common emitter transistor(TR) in a cascade amplifier circuit. CONSTITUTION:A constant current source I3 is connected to the collector terminal of a TR Q1 whose emitter is connected to ground and a constant current is supplied to the TR Q1. An emitter current I2 flowing to a common base TR Q2 is decreased by a bias current supplied from a constant current source I3 to the emitter current I1 of the TR Q1. Thus, the size of the TR Q2 is decreased by the current reduction to decrease capacitors CB2, CC2 which are parasitic on the collector terminal of the TR Q2. Thus, the amplifier circuit whose band is expanded without decreasing the gain is formed in comparison with a conventional cascade type amplifier circuit.

Title: Electronic hybrid circuit
Inventor: UENO NORIO
IPC: H04B1/58
Filed: 1980-02-18
Abstract: PURPOSE:To ensure a small-size and economical connection between the unbalanced 2-wire and 4-wire circuits,by setting the impedance of the artificial load of the balance network higher than the impedance of the unbalanced 2-wire circuit. CONSTITUTION:The balance network 5 includes the resistances Ra and Rb plus the artificial load Zp. These resistances Ra and Rb are selected so that the impedance of the load Zp is higher than the impedance of the unbalanced 2-wire circuit. The input signal of the input termianl 1 in the unbalanced 4-wire circuit is delivered to the input terminal 3 via the differential amplifier 4. The component supplied to the differential amplifier 6 from the terminal 3 via the resistance R3 is identical to the component supplied to the amplifier 6 from point (b) via the netwofk 5. As a result, the input signal supplied through the terminal 1 never turns into the terminal 2. The input signal applied to the terminal 3 from the unbalanced 2-wire circuit is delivered to the terminal 2 from the amplifier 6 since the component supplied to the amplifier 6 via the resistance 3 is larger than the component supplied via the network 5.

Title: Joining method for porous metal
Inventor: MORIMOTO KAZUO
IPC: B23K11/16
Filed: 1986-01-30
Abstract: PURPOSE:To form a large-sized plate, etc. inexpensively with excellent strength and heat resistance of the joining part by depositing the joining part with its heating and pressing by passing a current in the state of abutting mutual joining faces. CONSTITUTION:A current is passed through an electrode 3 by press-fitting joining faces 6, 7 by moving a foamed Al plate 1 in the direction of a foamed Al plate 2. The foamed Al plate 2 retreats with the reaction force in some degrees by the means of a spring, etc. and the further retreat is stopped with an operative plate 80 abutting to a stopper 81 when the reaction force reaches to a fixed value by being pressed by the Al plate 1. The press-contacting force between the joining faces 6, 7 is accordingly set to the prescribed value. The diaphragm of the foam is bent by performing the heating and melting in the press-contacting state, becoming in a linear contact state from a point contact state or in a face contact state with the mutual diaphragms being overlapped. The generation of burrs is prevented and the joining can be performed so that no seam can be seen from the external appearance when the joining is performed with the press-contacting each other by the minimum force which forms this linear or face contact state, namely the force which crushes no foam.
