Title: Manufacture of seamless steel tube and mandrel mill used therefor
Inventor: OCHI SHIGEHARU
IPC: B21B17/04
Filed: 1994-02-09
Abstract: PURPOSE:To provide a method for manufacturing a seamless steel tube excellent in the accuracy of outside diameter without generating defective biting and roll mark and mandrel mill used therefor in rolling technique using a two-roll mill of plural stands and four-roll mill of the stand of the final stage. CONSTITUTION:A tube stock is successively rolled with the two-roll mills for rolling of >=2 stands in which mandrel bars having the same diameter are used and which are continuously arranged in 90 deg. phase and next, shaping rolled with the two-roll mill for shaping from the direction inclined by 90 deg. to the rolling direction of the final stand of the two-roll mill for rolling. At last, the finished thickness of the steel tube is changed by rolling the tube stock with the four-roll mill from four directions that are inclined by 45 deg. to the rolling direction of the two-roll mill of the final stand and changing the rolling reduction in the two-roll mill and four-roll mill. Since the spreading of the steel tube is corrected into a circle with the two-roll mill for shaping on the inlet side of the four-roll mill, defective biting and roll mark are not generated and the steel tube excellent in the accuracy of outside diameter is obtained.

Abstract: PURPOSE:To lower the parasitic resistance without losing the effect of surface stabilization by inserting a thin N type GaAs layer into the intermediate part of an undoped GaAs layer. CONSTITUTION:An undoped GaAs buffer layer 2, an N type GaAs actuating layer 3, an undoped GaAs layer 4, an N type GaAs layer 7, the undoped GaAs layer 4 again, an N<+>GaAs layer 6 are successively grown on a semiinsulating GaAs substrate 1. Next, a prospective channel region is etched away to form a recess. Next, after etching away a prospective gate region, a gate electrode metal is deposited and then lifted off to form a gate electrode 5. Next, after etching away a prospective ohmic electrode, AuGe/Ni is evaporated and then lifted off to form an ohmic electrode 8. Later, the whole body is heat-treated to make an ohmic contact. Through these procedures, the resistance of the N type layer 7 to the N<+>type layer 6 and the actuating later 3 can be lowered down to the value not exceeding 1/2 thereby enabling the parasitic resistance to be lowered.

Abstract: PURPOSE:To attain a supervisory system constituting easily and economically supervisory lines by constituting relays installed to terminal station devices and repeaters and their contacts into a closed circuit at a failure so as to measure a DC loop resistance. CONSTITUTION:Make contacts of relay contacts are constituted in series and brake contacts are constituted in parallel. For example, if a repeater 2 is failed, a realy 5 is activated, its contact 5'' is closed and its contact 5''' is opened.

Then, a loop through a relay contact 4''' is constituted when the loop is viewed from a measuring device 10, and the discrimination of location is attained by measuring this loop resistance. In the supervisory system discriminating the failed part by the measurement of loop resistance, since the system is constituted by a couple of supervisory lines, the economy and ease of measurement are attained.

IPC: G01R31/319
Filed: 1986-02-21
Abstract: PURPOSE:To generate an algorithmic pattern for a complicate function test at a high speed by detecting the parity of an optional bit group of an ALU output register and shifting the detection result in an ALU. CONSTITUTION:The contents of the ALU output register 5 are ANDed with the contents of a bit selection register 6 and the result is sent to a parity detecting circuit 8. The circuit 8 detects the parity and supplies the result as a shift input to the ALU 3 with a shift-in function. In case a pseudo random number is generated, a proper value is set in the register to select bits supplied from the register 5 to a circuit and also specify shift arithmetic as the arithmetic of the ALU 3. Further, a selector 4 also specifies the side of the register 5. In this state, when this algorithmic pattern generating circuit is operated, the contents of the register 5 are shifted in order. Thus, the pseudo random number is generated at a high speed to take the function test of a semiconductor at a high speed.

Filed: 1980-03-25
Abstract: PURPOSE:To enable reproduction of an image always easily visible irrespective of conditions of an original, by changing developing characteristics in accordance with exposure controlled with an exposure controller. CONSTITUTION:Image reproductivity can be changed by changing resistance of resistor 3 connected in series to the sleeve of developing device 2.
