Title: Thickness controlling device for seamless tube rolling mill
Inventor: UEDA NORIO
IPC: B21B37/18
Filed: 1981-05-27
Abstract: PURPOSE:To make thickness of tubes constant by calculating the amount of drawing position control that makes the difference between calculated thickness in the outlet side of a rolling mill and target thickness in the outlet side zero, and giving it to a drawing position controlling device. CONSTITUTION:An inlet side speed detector 40 detects the speed (v) of a rolling material in the inlet side of a rolling mill and an outlet side speed detector 50 detects the speed V of the rolling stock in the outlet side. An outlet side thickness calculator 810 inputs the output (v) and V of detectors 40 and 50. At the same time, it inputs inlet side sectional area (a) and plug diameter D of storage devices 90 and 100 and calculates the thickness T of the rolling material in the outlet side of the rolling mill. A drawing position calculator 820 calculates and outputs a drawing position control signal DELTAS that makes the difference between T and T' zero using calculated outlet side thickness T and target thickness T'. The amount of rolling position control DELTAS is given to a drawing position controlling device 60, and drawing position of rolls 20 is corrected. By this way, the thickness in the outlet side of the rolling mill is controlled to the target value T' and a seamless tube of desired thickness is manufactured.

Title: Production of high corrosion resistant coated steel material
Inventor: IKENO TERUO
IPC: C23C28/00
Filed: 1978-06-30
Abstract: PURPOSE:To impart corrosion resistance by forming a manganese-manganese hydrate oxide layer or further oil coating layer on the surfaces of steel material. CONSTITUTION:Mn is electroplated to thicknesses of 0.4 to 8mu on steel material surfaces. After the plating surfaces are rinsed, they are dried and the steel material is dipped in an aqueous solution containing hexad Cr ions up to 5g/l to saturated concentration. Or it is subjected to cathode electrolysis treatment at current density of 2A/dm<2> or over in the same solution to form a Mn hydrate oxide layer. The Mn- plated surfaces are stabilized by the Mn hydrate oxide layer to considerably improve corrosion resistance. Hexad chrominum ions do not exist in this Mn-hydrate oxide layer which is only the magnanese hydrate oxide layer, but it has a property of easy adsorbing oils and fats and therefore rust preventive oil or lubricating oil is coated to thicknesses of 0.1 to 5g/m<2> to additionally improve ths corrosion resistance.

Title: Semiconductor laser apparatus and method of driving same
Inventor: ISHIKAWA MAKOTO
IPC: H01S5/068
Filed: 1988-03-31
Abstract: PURPOSE:To realize a high-output and low-noise characteristic which is optimum as a light source of an addition-record and rewrite type optical disk or the like even without using a high-frequency superposed circuit by a method wherein a switch used to connect a second conductivity type electrode layer in an absorption region to a first conductivity type semiconductor substrate is installed and an excitation region is coupled optically to the absorption region. CONSTITUTION:While an absorption region 11 and an excitation region 12 are kept optically coupled by means of an electrode-separating groove 13, a semiconductor laminate structure is separated electrically into the absorption region 11 and the excitation region 12; a switch 14 which connects a second conductivity type electrode layer in the absorption region to a first conductivity type semiconductor substrate directly or via a resistance in accordance with a control signal supplied from the outside is installed. When the changeover switch 14 is connected to B, the absorption region 11 is grounded and this absorption region 11 functions as an oversaturation absorber; accordingly, a self-oscillation is generated and a low-noise characteristic can be obtained. On the other hand, when the changeover switch 14 is connected to A, a carrier is injected also to the absorption region 11 in the same manner as in the excitation region 12, and a high-output characteristic can be obtained. Accordingly, when the switch 14 is changed over in synchronization with a changeover operation between a drive voltage V2 at a high output and a drive voltage V1 at a low output, a low-noise oscillation and a high-output oscillation can be obtained alternately.

Title: Load switch or load-cutting switch and switching circuit device having fuse
Inventor: KAARU SHIYUTEEKUMIYURAA
IPC: H02H7/22
Filed: 1991-04-12
Abstract: PURPOSE: To reduce a load in a lower working area by connecting a switch in parallel with a fuse that opens when an electric current value exceeds an allowable value. CONSTITUTION: An auxiliary switch 7 opens if a current value of an electric current circuit exceeds an allowable value. A breaking time of a fuse 3 is set to be not longer than a proper time of a load cut-off switch so as not to trip the switch 7 by an excessively high electric current pulse such as in current energizing. If a fault current that exceeds that allowable value is generated, a magnetic contact 14 forms a magnetic field to pull out a switch pin 9 from a facing electrode 13, and the switch 7 is switched to carrentless condition. After opening switch contact zones 9, 13, the fuse 3 burns off to break the electric current circuit. That is, fusing starts just when the pin 9 stops short- circuiting the fuse 13. The switch 7 removes a preload being applied to the fuse 3, and a main switch switches a comparatively lower current strength.  Therefore, a load in a lower area of a working current and the like can be reduced.

Title: Coolant natural circulation type heat transferring device
Inventor: TANAKA HIROKUNI
IPC: F24F5/00
Filed: 1988-03-31
Abstract: PURPOSE:To make a cooling capability of a plurality of evaporators arranged side by side in a vertical direction constant by a method wherein a liquid level holding device for forming a coolant liquid column having a specified liquid height in reference to a coolant liquid surface of each of evaporators within a part of an inlet port of each of the evaporators of a liquid coolant pipe is arranged in the midway of the liquid coolant piping in correspondence with each of the evaporators. CONSTITUTION:It is possible to equalize a liquid level of a coolant liquid column P1 formed by a first liquid level holding device 6 in a first evaporator 1 mounted at a low position with a liquid level of a coolant liquid column P2 formed by a second liquid level holding device 7 in a second evaporator 2 mounted at a high position. Accordingly, coolant pressures in the first evaporator 1 ad the second evaporator 2 are equal to each other and then evaporating temperature of a coolants are also equal to each other. With this arrangement, as each of the evaporators 1 and 2, a temperature difference between an evaporating temperature and a cooled air (indoor side) around each of the evaporators 1 and 2 become the same. Cooling capabilities of each of the evaporators 1 and 2 arranged side-by-side in a vertical direction can be made the same to each other, resulting in that a cooling efficiency of a room where each of the evaporators 1 and 2 is installed can be made the same even if a temperature difference in the room is varied.
