Title: Manufacture of cold rolled steel plate excellent in workability
Inventor: TOKUNAGA YOSHIKUNI
IPC: C21D8/02
Filed: 1980-05-01
Abstract: PURPOSE:To obtain a cold rolled steel plate excellent in workability by continuous annealing by adding specified components in adjusting the composition before performing continuous casting and blowing gaseous N2 into the tundish to adjust N component slightly within a delicate range. CONSTITUTION:The composition of steel taken out from a converter is adjusted to 0.015-0.05% C, 0.05-0.4% Mn, 0.01-0.08% Al, 10-80ppm N and 7- 50ppm B. At this time, if required, N2 gas is blown into the tundish or ladle and the relation between B and N is fine-adjusted to -5<=N-B/0.8<=35ppm. This molten steel is made to slab and hot rolled and cold rolled. By this method, crystal grains grow in a short time without raising temperature in continuous annealing furnace, and material of mild steel plate suitable for press-working is obtained.

Filed: 1988-03-14
Abstract: PURPOSE:To make it possible to accurately and stably detect the end point of etching by providing a heater at the window part to be used for detection of the end point. CONSTITUTION:A heater wire 12 is adhered to the outer side face of a quartz sheet glass 11 using heat-resistant resin 13, and a terminal part 14 is provided at both end parts of the heater wire 12.

When the quartz sheet glass 11 of the window part is heated up to 60-80 deg.C, a deposition film is adhered to the inner side wall of the chamber, but the deposition film is hardly adhered to the quartz sheet glass 11 of the window part. By having the state wherein the deposition film is hardly adhered to the window part, an emission spectrum can be picked out through the window part even when the number of treated wafers is increased, the detection of light intensity by a spectro-chemical analyzer can be improved, and the end point of etching can also be detected accurately.

Title: Traction limiting device for speed shift of row-crop tractor
Inventor: NAKAGAWA HIDEAKI
IPC: B60K20/00
Filed: 1983-04-04
Abstract: PURPOSE:To make it possible to shift a transmission unit to a backward low speed stage to enlarge the working range of a row-crop tractor, and as well to aim at enhancing the efficiency of working, by providing a tranction mechanism which inhibits the transmission unit from being shifted to the backward high speed stage when a steering wheel is set in respective direction. CONSTITUTION:In the condition in which a main speed shift mechanism 8 is set at its backward maximum speed stage, a backward side shifter boss 11 pushes the piece 33a of a traction limiting arm 33 remotely from a stopper 36 so that it approaches a position below the traction limiting part 23a of a high speed stage tension arm 23 in a counter shift-gear mechanism. Then, even if the tension arm 23 is intended to rotate in the direction in which a belt is tensed, the traction limiting arm 32 abuts against the traction limiting part 23a from the lower side thereof, and therefore, the tension arm 23 is inhibited from rotating by the traction limiting arm 32 which is biased by a torque spring 34 to rotate upward as shown in the direction of the arrow. Accordingly, a counter shift- gear is inhibited from being shifted to the high speed stage, but may be shifted into the low speed stage irrespective of the traction arm 32. With this arrangement, the low speed backward movement of the row-crop tractor may be made, and therefore, the efficiency of working is enhanced.
