Filed: 1985-04-22
Abstract: PURPOSE:To reduce a stage and to widen the range for selection of an adhesive agent by melting fusing glass in a rotating magnetic field at the temp. lower than the crystallization temp. of an amorphous metal. CONSTITUTION:A work 1 consisting of the amorphous alloy film which is a core material for a magnetic head and is formed by sputtering on a substrate and the fused glass film which has the m.p. lower than the amorphous crystallization temp. and is formed by sputtering is held by a pressurizing jig 2 and is fixed to a table 3. The work 1 is heated up to the amorphous alloy crystallization temp. by a heater 5 and while the table 3 is rotated, a magnetic field is applied to the work by a magnet 6. The pinning of the magnetic wall is eliminated by the heat treatment and the uniaxial anisotropy is negated by the rotating magnetic head by which the core material for a head having high magnetic permeability is obtd. The stage is thus reduced by executing simultaneously the improvement of the soft magnetism and the adhesion of the substrate and since the adhering temp. can be increased up to the crystallization temp., the range for selecting theadhesive agent is widened.

Title: Halftone recording system
Inventor: YAMADA MITSURU
IPC: H04N1/23
Filed: 1989-04-04
Abstract: PURPOSE:To prevent the fluctuation of recording densities of the same gradation level to obtain a uniform recording density by a method wherein an offset value is set in accordance with a heat accumulation state of heating resistors during a recording action, and an energy to be applied to each heating resistor is set so as to eliminate the influence of the accumulation state. CONSTITUTION:When gradation level signals are successively inputted to an input terminal 1, a gradation level signal judgement means 4 finds a heat accumulation index for recording appropriate one dot. A heat accumulation index counting means 5 successively accumulates the outputted heat accumulation indexes from the start of recording with respect to all heating resistors and outputs the cumulative heat accumulation indexes obtained so far to a sequential pulse generation means 2 at every completion of the accumulation for one line. On the basis of the cumulative heat accumulation indexes, the pulse generation means 2 finds an offset value of a conduction pulse number to be supplied to the respective heating resistors with respect to a line to be recorded next. Using the set pulse number corresponding to a section for the 1st gradation as the offset value, a pulse number corresponding to the inputted gradation level signal is determined, and a recording is performed by supplying the conduction pulses to the respective heating resistors.

IPC: F01N13/04
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To correct shift in the output originating from degradation, etc., of an NOx sensor. SOLUTION: An NOx occluding/reducing catalyst 7 is installed in the exhaust passage 2 of an internal combustion engine 1, and the NOx concentration in the exhaust gas after passage of catalyst 7 is detected by an NOx sensor 33. An electronic control unit(ECU) 30 of an engine 1 operates the engine with the rich air-fuel ratio for a short time each time the sensed NOx concentration increases to a prescribed value and performs the regenerative process of the NOx occluding/reducing catalyst 7.  Also the ECU learns the shift of the NOx sensor output from the reference value (output corresponding to the NOx concentration being zero) and the NOx sensor output, when the engine is operated in the condition that the NOx emission in the low-load operation, etc., at a lean air-fuel ratio is less and also the NOx occluding/reducing catalyst is functioning normally, i.e., in the condition that the NOx concentration in the exhaust gas reaching the NOx sensor becomes approx. zero and then corrects the NOx sensor output on the basis of the learnt value.
