IPC: H01L21/331
Filed: 1977-11-08
Abstract: PURPOSE: To expand the safe operating region by making the width of ballast resistance working as parasitic emitter and the base right beneath the ohmic connection part wider than the width right beneath the emitter.  
     CONSTITUTION: A deep P layer 21 and a P base 2 are selectively formed in an N epitaxial layer 1' on N +  Si substrate 1. N +  emitter layer 3 divided into 24 regions and adjacent ballast resistance 4 are selectively formed. At this time, the base width right beneath ohmic contact part 4' and resistance 4 is made wider than the width right beneath the emitter 3 by way of the P layer 21. The surface of layer 1' is covered with SiO 2  9, and electrodes 6, 7 are composed. When operating this device by reversely base-biasing, each emitter is free of current concentration owing to the effect of the resistance, and also in the parasitic element of connection part 4' of the resistance 4 current is not concentrated because the base width is wider twice, so that the safe operating region is sufficiently large.

Filed: 1977-11-10
Abstract: PURPOSE:To make it possible to use a cheap tape with the end by setting the tape of the answering side at the tape start position by control signals from a remote place. CONSTITUTION:The first signal (3 digits) is inputted as a tone signal to set R-S flip-flop 34 and make the remote control available. Next, when the second signal(1 digit) is imputted as a tone signal, this signal is taken out as a L-level signal by control signal generator circuit 22 to make R-S flip-flop 26 set-state through NAND circuit 35 and rewind the tape with the end of the answering side by H-level signals from output terminal 29. After all the tape is rewound, the tape end detection signal resets flip-flop 26. Thus, the rewind is released, and simultaneously, a signal is issued from terminal 32 by the charging of capacitor 31, thereby making the answering side recording-state.

Title: Joint for oil well pipe

IPC: C25D7/04
Filed: 1983-07-26
Abstract: PURPOSE:To provide a titled joint provided with excellent resistance to seizure by forming one kind among Cr, Mo and W alloys for the uppermost layer and a soft metal having low hardness and easy plastic deformability for the lower layer by multi-layer plating to specific thicknesses at a screw or metal sealing part. CONSTITUTION:A soft metal such as Cu, Zn, Sn, Pb or the like of >=2mu which has low hardness and is easily plastically deformable is plated for the lower layer of the screw or/and metal sealing part of an oil well pipe for which high airtightness is required and which is tightly screwed. One kind among Cr, Mo and W alloys is plated to a thickness of <=1/2 the entire plating thickness for the uppermost layer. Multi-layer plating of which the entire plating thickness is 3-50mu is formed on the above-mentioned part. The reasons for regulating the thickness of each plating layer are as follows. If the entire plating layer is <=3mu, there is no plating effect and if >=50mu, the plating is likely to be peeled. If the hard layer is >=1/2 the entire plating layer, the part for absorbing plastic deformation is smaller. If the soft layer is <=2mu, the effect of absorbing the plastic deformation and embedding the hard and broken pieces is not satisfactorily attained.
