Abstract: PURPOSE:To manufacture a line pipe excellent in corrosion resistance and weldability by heating a low carbon martensitic stainless slab to a specified temp., executing hot rolling, thereafter subjecting it to resistance butt seam welding to make a tube and executing specified heat treatment and cooling treatment. CONSTITUTION:A martensitic stainless slab contg. <=0.08wt.% C is heated to 1050 to 1300 deg.C, is thereafter hot-rolled into 4.0 to 25.4mm plate thickness and is coiled at >=600 deg.C. Next, this hot coil is cut and is subjected to resistance seam welding while it is formed into a cylindrical shape to make a tube. This resistance welded steel pipe is subjected to hardening of executing heating to the temp. range of 950 to 1100 deg.C for >=1min and thereafter executing cooling at least to <=300 deg.C at the cooling rate of that of air cooling or above. In this way, the structure of the steel pipe is formed into a one constituted of >=50vol.% martensite. Next, the steel pipe is reheated to the temp. of 550 deg.C to the AC1 transformation point, is held for >=1min, is thereafter cooled at least to <=300 deg.C at the cooling rate of that of air cooling or above and is tempered. In this way, a low carbon martensitic stainless steel pipe useful as a line pipe can be obtd.

Filed: 1989-12-15
Abstract: PURPOSE:To increase the absolute value of a detection value of a black level and to improve the detection performance of the black level by providing a shunt varying a current ratio of a cathode current flowing to a cathode current detection resistor at the detection of a white level and a black level. CONSTITUTION:A current flowing to cathodes 13R, 13G, 13B passes through a shunt comprising resistors R3R-R7R, transistors(TRs) Q2R,Q3R and a switch S1R through a TR Q1R and is fed to a cathode current detection resistor R1R, where the current is detected. Suppose that the shunt supplies the cathode current to the resistor R1R only and the ratio of black and white levels is 1:10, then the shunt is set so that 100% of the cathode current flows to the resistor R1R at the detection of the black level and 10% of the cathode current flows to the resistor R1R at the detection of the white level, it is possible to make the prescribed black level detection value equal to the white level detection value at the resistor R1R, thereby improving the detection performance of the black level.

Title: Revolving cylinder with built-in circuit
Inventor: MASUMOTO TSUTOMU
IPC: G11B5/02
Filed: 1990-11-29
Abstract: PURPOSE:To prevent the generation of beat due to a crosstalk and to completely erase recorded signals by inserting a low-pass filter circuit to block frequency components of erasing signals into a video signal recording circuit. CONSTITUTION:Into the video signal recording circuit from a signal transmission transformer 4Tr to a video head 1, a low-pass filter circuit LF is inserted. Consequently, since the signal level of the frequency components in which the erasing signal frequency is present thereon is reduced, even if the erasing signals are superposed, the maximum level of the erasing signal components is smaller than the video signal level, therefore the erasing signal does not flow into the video signal recording circuit. Consequently, the current of the erasing signal can be increased in stead, and the recorded video signals are completely erased, and simultaneously the generation of beat due to crosstalk is prevented.

Filed: 1988-12-23
Abstract: PURPOSE:To prevent ill influence upon the lifetime of a contact even in the case of contact is of mechanical type by changing over an emergency lighting control switch from On to Off when the AC mains are recovered, and changing over a lamp changeover switch from an emergency inverter circuit to a commercial inverter circuit until the lamp lifetime compensated operating time has elapsed thereafter. CONSTITUTION:When power failure on AC mains is recovered, oscillation of a commercial inverter circuit IN1 will start, and the oscillation output be impressed on a lamp. However, preheating of the lamp shall be made until the lamp lifetime compensated operation time has elapsed since the AC mains were recorded. After a certain while, a lamp changeover switch S1 is changed over from the emergency inverter circuit IN2 side to the commercial inverter circuit IN1. At this time, the oscillation motion of the inverter circuit IN2 is stopped through an emergency lighting control switch S2, and current supply to the lamp from the inverter circuit IN1 is in preheated condition even though the oscillating motion of the inverter circuit IN1 has been started, so that no contact arc will be generated at changeover operation of the changeover switch S1.
