Title: Production of stainless steel strip and steel sheet having excellent polishing property
Inventor: UEDA MASANORI
IPC: C21D8/02
Filed: 1986-05-02
Abstract: PURPOSE:To produce a stainless steel strip having excellent polishing property by subjecting a prescribed hot rolled stainless steel to mechanical descaling and pickling, then to a desmatting treatment and cold rolling under specific conditions followed by annealing and pickling. CONSTITUTION:After the hot rolled steel strip of a ferritic or martensitic stainless steel is taken up, the steel strip is subjected to mechanical descaling and is pickled with an acid of an active dissolution type essentially consisting of about 150-500g/l H2SO4 and about 30-300g/l HCl. The strip is then subjected to the desmatting treatment by hot water and abrasive polishing effect of brushes without drying the surface; thereafter the steel strip is cold rolled at >=30% draft by large-diameter rolls having >=200mm roll diameter. The strip is further continuously annealed at about 750-1,000 deg.C as final finish and is subjected to electrolytic nitric acid pickling, etc., after a salt treatment. Such steel sheet is subjected to bright annealing at the same temp., then to temper rolling at need. The stainless steel sheet which has the small surface roughness, has no fogging on the surface and has the excellent polishing property is thus obtd.

Abstract: PURPOSE:To accurately etch a substrate to be dry etched to an arbitrary depth by using a monitoring plate in which at least one layer of a thin film of substantially the same material as a product substrate is formed on the substrate for the plate as the monitoring plate. CONSTITUTION:At least one layer of a thin film of the same material as that of a product substrate 7 is formed on a substrate 10a of a monitoring plate 10. A reflected light (or transmitted light) of the plate 10 is monochromatized by a monochrometer 16 reversely to a beam splitter 15 during etching of the substrate 7, and an output signal corresponding to reflectivity is detected by a recorder 21 or a meter 22 through a photodetector 17, etc. Here, an end point of etching is known from a periodic change of an output signal. Thus, crests of a spectral curve can be clearly separately measured, and the end point of the etching which is not affected by influence of a thickness change of the plate due to thermal expansion of the product substrate can be detected.

IPC: H03K17/04
Filed: 1985-05-13
Abstract: PURPOSE:To obtain a drive circuit operating a switching element in high speed by adding the 3rd winding to a drive transformer and providing a transistor (TR) connected thereto. CONSTITUTION:When a TR 2 is turned on by a control signal 108, a current turning on a switching element 1 flows to the secondary winding 42 of the drive transformer 4. When the TR 2 transits from ON the OFF by the control signal 108, a base current flows to a TR 3 through a resistor 5 and a capacitor 6 and the TR 3 is going to transit from OFF to the ON state. Thus, a voltage is impressed to the ternary winding 43 and a voltage increasing the base current of the TR 3 is induced in the primary winding 41. Thus, the TR 3 is transited from OFF to the ON state quickly and a voltage giving a reverse bias to the switching element 1 is induced in the secondary winding 42 and the switching element 1 is transited quickly from the ON to the OFF state.

Title: Control system for copying machine
Inventor: UCHIDA KEIICHI
IPC: B65H37/04
Filed: 1984-05-22
Abstract: PURPOSE:To check economically and efficiently the operation of a stapling binder by detecting the input of the operation command for said binder in a diagnosis mode and operating the binder in the state of prohibiting the copying operation. CONSTITUTION:An operator sets the operation mode of a copying machine at the diagnosis mode by turning on an SE mode select switch 132 and operates a start switch 130 after inputting the operation command for checking the operation of a binding mechanism 20 as a check number from numeric keys 131. A CPU11 drives a staple motor 14 to actuate the mechanism 20 by judging that the operation command for the mechanism 20 is inputted thereto. The operator operates again the switch 132 to turn off the switch and to release the diagnosis mode after confirming that the mechanism 20 operates correctly. The operation check of the mechanism 20 is thus made possible without the copying operation.
