IPC: H03M13/23
Filed: 1984-03-23
Abstract: PURPOSE:To offer the system quickening an information transmission speed by applying pipeline processing to an ACS (addition/comparison/selection) circuit of a coder and a Viterbi decoder. CONSTITUTION:When an even (or odd) order bit of a transmission information series 1 is placed at the 2nd and 4th order from the left of a flip-flop, an adder 6 sums up them by modulo 2 to and the result is outputted. During this time, the odd (or even) order bit is placed at the 1st and 3rd bit from the left of the flip- flop and the system is in standby state while conducting nothing until the next clock is inputted. The transmitted information series is separated into even number order series and odd number order series, and the even number symbol series applied with coding for the even order number series and the odd order number symbol series applied with coding for only the odd number series are interleaved and an output symbol is obtained.

Title: Semiconductor device
Inventor: ITO MINORU
IPC: H01L27/02
Filed: 1985-03-20
Abstract: PURPOSE:To enhance a protective capability against surge, by providing an impurity diffusion having the same polarity as a substrate in the vicinity of a diode and an output diffusion. CONSTITUTION:Immediately after a VSS voltage impression terminal 4 is grounded and a negative surge is impressed on the output terminal 1 of an output transistor, an output P<+> diffusion 9 turns to be of negative high voltage, while an N substrate 6 near the output P<+> diffusion 9 and an N<+> diffusion 8 connected to a VDD voltage impression terminal 2 turn to be of negative high voltage which is smaller by the inverse voltage resistance of a PN junction than that of the output P<+> diffusion 9. A P<+> diffusion diode region 7 connected to the gate 10 of the output transistor turns to be of negative voltage smaller by a forward rise voltage (about 1V) of the PN junction than that of the N<+> diffusion 8. The reduction of the inverse voltage resistance of the PN junction to 30V or less can be realized easily by controlling a substrate concentration, a diffusion concentration and a channel stopper concentration, and thus this output transistor can be protected against the surge.

Abstract: PURPOSE:To ensure a solid and precise connection of a tone pipe to a member to be connected by an adhesive by forming the pipe by compression so that the outer circumferential section has an oval shape and the burrs caused at the longer diameter part and then finishing the pipe with elimintion of the burrs. CONSTITUTION:A pipe molding cavity 4 is formed in cooperation with the upper and lower molds 1 and 2 plus a core metal 3. The outer circumferential section of the cavity 4 has an oval shape. Thus a pipe 6 having burrs 5 at its longer diameter part is obtained. The longer and shorter diameters of the pipe 6 are set at D+DELTAD and D-DELTAD respectively, and thus an oval pipe 6 having a longer diameter D and a shorter diameter D-DELTAD is obtained by carrying out a drawing work with a dice having an inner diameter D. A member 8 to be connected such as a pipe holder or the like is connected to the pipe 6, and a hole 8a is made into a perfect circle having an inner diameter D+DELTAE. As a result, the clearance between the hole 8a and the longer diameter part of a pipe 6' has the minimum extent DELTAE only that is necessary for fitting.
