Title: High strength cold rolled steel sheet having superior local ductility and stable baking hardenability of coating, produced by continuous annealing
Inventor: SHIODA KOSAKU
IPC: C22C38/06
Filed: 1994-01-31
Abstract: PURPOSE:To provide superior local ductility and strain ageing characteristic and stable baking hardenability of coating by continuously annealing an Al killed steel sheet of specific composition and specifying solid-solution carbon content and transgranular cementite density, respectively. CONSTITUTION:This steel has a chemical composition consisting of, by weight, 0.01-0.04% C, 0.005-0.4% Si, 0.05-0.30% Mn, >0.08-0.13% P, 0.003-0.02% S, 0.015-0.15% Al, <=0.0040% N, and the balance Fe with inevitable impurities. This low carbon Al killed steel is hot-rolled, cold-rolled, continuously annealed, and temper-rolled. By this treatment, solid-solution carbon content is regulated to 3-12ppm. Transgranular cementite density (rho, piece/mm<2>) satisfies an inequality rho<=(0.034XAl+3.0)X10<5> in the relation with aging index (Al, MPa). By this method, the cold rolled steel sheet in which LDH0 as (100 deg.CX1h) local ductility index after artificial aging treatment is regulated to 22mm and which has 30-80MPa baking hardenability of coating and 380-450MPa class strength level, can be obtained.

Abstract: PROBLEM TO BE SOLVED: To accurately control the shape of a recess by forming a source electrode and a drain electrode so that the recess side edge part projects onto the recess at both sides of a semiconductor region surface, and arranging the gate electrode in the recess of the semiconductor region. SOLUTION: A source electrode 12 and a drain electrode 13 are formed on an n-type GaAs layer 11 so that they oppose each other with a specific gap.

IPC: H03K5/02
Filed: 1994-02-01
Abstract: PURPOSE:To cope with the transmission lines of various characteristics and to appropriately perform sag correction even when a DC offset voltage is present between a first signal and a second signal. CONSTITUTION:When the first signal and the second signal whose phase is inverted from the first signal are inputted, a third differential amplifier part 38 outputs a first amplification signal for which the phase is inverted and a voltage is amplified for the first signal and a second amplification signal for which the phase is inverted and the voltage is amplified for the second signal.

Title: Driving controller of electric motor for hydraulic braking apparatus
Inventor: SUZUKI MASAKUNI
IPC: B60T8/34
Filed: 1994-02-01
Abstract: PURPOSE:To stop the rotation by the inertia after an electric motor is cut off from a power supply and relieve a passenger from uncomfortableness. CONSTITUTION:After the finish of initial checking, antiskid control, etc., a switching unit 204 is turned off and an electric motor 80 is cut off from a driving power supply 190. A resistor 206 is connected to the motor 80 and a regenerative braking circuit 212 is closed. As an electric energy produced by the rotation of the motor 80 by the inertia is consumed in the resistor 206, the rotation is quickly suppressed. In other words, the continuing time of the residual rotation of the motor caused by the inertia is reduced compared with the continuing time of a conventional constitution, so that a passenger can be relieved from the uncomfortableness such as a rotation noise and radio noise.

Filed: 1982-01-27
Abstract: PURPOSE:To eliminate errors by fluctuations in the amplification factor of an amplifier and to measure micro currents such as leak currents of semiconductors with good stability and accuracy by comparing the micro current to be measured and reference current and measuring the difference thereof. CONSTITUTION:Leak current il to be measured is supplied to the inversion input terminal of an operational amplifier 21. The voltage signal which increases gradually from 0V is generated from a reference voltage generator 20, and reference current ig is increased gradually. In this case, right after the start of measurement, the current il is larger than the current ig, and the output signal of the amplifier 21 is negative. The negative output signal thereof is outputted to a control line E. Right after the voltage of the generator 20 rises to ig=il and further to ig>il, the output signal of the amplifier 21 inverts positive, and the output voltage of the generator 20 at this moment is sampled and held with a capacitor 27 and is read out from an output terminal B. Thus, from the relation il=iR=V/R<3>, the value of the leak current il is determind.

Title: X ray exposuring device
Inventor: OKADA KOUICHI
IPC: G03F9/00
Filed: 1980-02-01
Abstract: PURPOSE:To make it possible to conduct positioning with high precision, by measuring the X ray amount using pattern asymmetric to the positioning mark. CONSTITUTION:As generally known, marks 24 on a wafer 23 correspond to marks 22 on a mask 21. The precise positioning can be ascertained by identical amount of X rays that are radiated on the mask passed through on the left and the right side and detected 25. In the present method, the shape of the marks are asymmetric. When positioning matches, an Au mark 31 on the mask falls on a mark 32 on the wafer precisely. The marks on the right side likewise fall on each other precisely. The X rays pass through the penetration region 100 and are measured. Measurement on both sides are identical. If the positioning is not precise, the X ray penetration regions below the left and right marks are 101, 101' respectively, not identical. The difference is returned back to the driving system of the wafer so that the measurement on both sides are identical. With such an arrangement, positioning by the X ray flux that has been not feasible hitherto can be made possible to the copying the ultra fine patterns.
