Title: Galvanization of oxidized scale-stuck hot rolled steel sheet
Inventor: AOKI TOMOHISA
IPC: C23C2/02
Filed: 1994-08-08
Abstract: PURPOSE:To prevent the generation of ruggedness on the plated layer in a steel sheet by subjecting a hot rolled steel sheet to reducing treatment while scales are stuck thereto, grinding the face of the steel sheet by a roll whose surface has ruggedness and thereafter applying galvanization thereto. CONSTITUTION:A hot rolled steel sheet is subjected to reducing treatment at 300, to 750 deg.C in an atmosphere of a reducing gas such as hydrogen while oxidized scales are stuck to the surface. Next, at the time of galvanizing, the surface of the steel sheet is ground by using a roller having ruggedness on the surface on the inlet side in a plating tank and is thereafter passed through a galvanizing bath. Since reduced iron on the surface of the steel sheet is removed away before the plating, a plated layer having a smooth surface can be obtd.

Title: Circuit and method for generating high-speed pulse
Inventor: EMORI SHINJI
IPC: H03K17/04
Filed: 1981-12-23
Abstract: PURPOSE:To allow a transistor (TR) having low dielectric strength to peform high-speed switching operation by a small input current, by driving the TR by a power voltage which is higher than its collector-emitter breakdown voltage and lower than its collector-base breakdown voltage. CONSTITUTION:The TRT1 is grounded at its emitter and applied at the base with an input pulse I through an input resistance RB, and its collector is connected to an output terminal OUT and also connected to a power source circuit PW through a load resistance RL. A voltage VCC applied to the collector from the power source circuit PW through the load resistance RL is higher than the collector-emitter breakdown voltage (BVCEO) and lower than the collector-base breakdown voltage (BVCBO). The power voltage VCC is higher than the collector-emitter breakdown voltage BVCEO, so the fall of an output voltage corresponding to the rise of the input pulse is extremely abrupt. Namely, a large current IC is flowed by a base driving current which is not enough large to turn on the TRT1.

IPC: H01C17/24
Filed: 1999-07-22
Abstract: PROBLEM TO BE SOLVED: To improve accuracy of the resistance value adjustment of a film type resistor by avoiding concentration of generated heat, by constituting a resistance film of first portions adjoining both terminal electrodes or either of the electrodes and a second portion, making the resistance of the first portions higher than that of the second portion, and at the same time, engraving a resistance value adjusting trimming groove into the second portion. SOLUTION: A film-type resistor has a structure such that a resistance film 2 is constituted of first portions 2a, adjoining both ends of the film 2 and having a length L1, and a second portion 2b positioned between the first portions 2a substantially at the central part of the film 2 and having a length L2. The resistance value of the film 2 is adjusted to a prescribed value by making the resistances of the first portions L1 higher than that of the second portion 2b, by forming the portions 2a in a zigzag manner having narrower widths and longer lengths than the second portion 2b has, while engraving a trimming groove into the second portion 2b so as to lower the resistance value of the portion 2b.  Therefore, the reduction of the resistance value of the film 2 to the prescribed value can be distributed to the engraving of the trimming groove into the second portions 2b having the lower resistance value and the increase in the resistance values of the first portions 2a.
