Title: Method for controlling heat gain in alloying furnace of galvannealed steel strip
Inventor: NAKAMURA ISAO
IPC: C23C2/28
Filed: 1991-10-08
Abstract: PURPOSE:To obtain a galvannealed steel strip of quality in which harf backing is prevented by compensating the set value of a heat gain so that the actual value of the temp. and emissivity or reflectance of a steel strip on the outlet side of a soaking zone of an alloying treating furnace can approach the target value. CONSTITUTION:A steel strip 2 is passed through a galvanizing bath 1, and after that, coating weight is controlled by a nozzle 3. Next, heating is executed by an alloying furnace 4 to alloy iron and zinc. At this time, the set value of a heat gain and the target value of the sheet temp. and emissivity of the steel strip 2 on the outlet side of a soaking zone 4b are found based on the kinds of the steel strip, its coating weight and the sheet passing rate. On the other hand, the sheet temp. and emissivity of the plated steel strip are measured and detected. To the measured value Tx and epsilonx, the compensating quantities are respectively found from the deviation with the target value To and epsilono. Next, the set value of the above heat gain is corrected by the above compensating quantities in a range in which both the sheet temp. and emissivity do not fall below the target value. The heat input to the heating zone 4 is controlled based on the above corrected value, by which the above sheet temp. and emissivity are allowed to approach each target value.

Title: Method of controlling voltage type inverter
Inventor: MATSUI TAKAYUKI
IPC: H02M7/48
Filed: 1988-10-19
Abstract: PURPOSE:To compensate the output voltage drop caused by the ON-delay without measuring output voltage and current by correcting the pulse widths of each arm depending on the information on current polarity of each phase to each region calculated in advance into which the direction of inverter current vector is divided. CONSTITUTION:From an exciting current command signal Id* and a torque current command signal Iq* voltage command signals Vd* and Vq* of a rotating field coordinate system are calculated with a voltage computing element 4 and they are converted into AC voltage command signals vu*, vv* and vw* of a stator coordinate system with a coordinate transformation computing element 5. If these signals are corrected into pulse signals of each phase with a PWM pulse computing element 6, they are divided into six state regions based on the polar signals of each phase from a polarity discriminator 8. By the operating method corresponding to each region, correction operation of ON timing and OFF timing is performed. The sinusoidal wave output is obtained as a result.

Abstract: PURPOSE:To attain the correlation duplicated sampling method by connecting at least two sample holding circuits to an output circuit of a CCD. CONSTITUTION:At least two sample holding circuits 21, 22 are connected to the output circuit of the CCD, the sample holding circuits apply sample and hold sequentially at each signal read period, the two each sample holding circuits 23, 24 and 25, 26 are connected respectively after the sample holding circuits, the sample holding circuit of the post-stage applies sample and hold to the output of the sample holding circuit of the pre-stage alternately at each signal read period, and a difference of the sample holding circuit of the post- stage applying sample holding at the same signal period is an output of the signal read circuit. Since the correlation duplicated sampling processing is applied by using a pulse where the speed and timing accuracy are relaxed, the reset noise of an image sensor with higher speed and higher picture element number is eliminated.

Title: Optical evaluation of crystal using infrared ray
Inventor: IKEDO TOSHI
IPC: G02B6/00
Filed: 1986-11-04
Abstract: PURPOSE:To rate the propriety of a crystal easily and with a high accuracy, by using a laser beam with a wavelength in the visible or ultraviolet region to discover a foreign matter causing a scattered light as contained in a crystal. CONSTITUTION:Irradiation laser 1 uses a visible laser such as He-Ne laser and Ar laser, or an ultraviolet range laser depending on cases. A laser beam 2 emitted from a laser 1 is irradiated to detect a scattered light generated from bubbles and foreign particles contained in an infrared optical crystal 3 with a light receiving element 4. Since the quantity of the scattered light varies with the size of bubbles and foreign particles in a fiber used in the infrared range or light irradiated, it is measured quantitatively and hence, a crystal below a fixed reference is used.

Title: Magnetic recording medium
Inventor: MATSUDA SHOJI
IPC: G11B5/66
Filed: 1993-10-20
Abstract: PURPOSE:To prevent head crash as well as to solve sticking by interposing an underlayer of a C-Si compd. having a prescribed value or below as the standard deviation of height of surface protrusions between a nonmagnetic substrate and a magnetic layer. CONSTITUTION:An underlayer 2 made of an SiC film is formed by vacuum CVD on one principal face of a mirror-polished Si substrate 1. In the underlayer, the atomic ratio of SiC is about 1:1. An intermediate layer 3, a magnetic layer 4, a protective layer 5 and a lubricative layer 6 are then successively laminated by magnetron sputtering. For example, the magnetic layer 4 is an Ni added Co layer, the intermediate layer 3 is a Cr, Mo or Cr-Mo alloy layer, the protective layer 5 is a carbon layer and the lubricative layer 6 is a hydrocarbon layer. The surface ruggedness of the underlayer 2 is regulated so as to attain <=0.5nm standard deviation of height of protrusions and the surface of the resulting recording medium is made similarly rugged. Since the height of the surface protrusions is small, the problem of sticking is solved and head crash phenomenon is satisfactorily prevented.

Filed: 1996-09-10
Abstract: PROBLEM TO BE SOLVED: To provide a lithium secondary battery with high charging and discharging capacity by composing an anode active material of cokes and graphite and specifying the addition amount of the graphite. SOLUTION: The addition amount of graphite is controlled to be 2-40wt.% to the total amount (100wt.%) of cokes and graphite.

Cavities 11 are formed between end parts 12 of a coke crystallite 10 and end parts 12 of other coke crystallites 10 and lithium clusters 20 produced from lithium ions 2 are absorbed and stored in the cavities. As a result, much more lithium ions can be absorbed and stored and an anode for a lithium secondary battery having high charging and discharging capacity can be obtained.

Abstract: PURPOSE:To resolve a problem that data cannot be reproduced at for example, the time of the leading of a tape high speed travelling by controlling the automatically the revolution of a cylinder motor so that the relative speed with a head can be constant in accordance with the travelling speed of the tape. CONSTITUTION:The error amplifier 29 of a tape travelling speed error detecting means 18 compares a tape speed detecting signal eT supplied to a positive phase input terminal with the reference value ET of the eT coincident with a tape high speed travelling target value supplied to a reverse phase input terminal, and outputs an error signal in accordance with the tape speed. For example, when resistances 30-33 are set to the same value, the eT and the ET are com pared by 1:1, therefore, an output Er goes to the one shifting a characteristic in a vertical axis direction to a tape travelling speed by ET only. Thus, when the tape speed is at the rising process toward the revolution the target value, the automatic follow-up is executed for a cylinder so that the relative head with a head can be constant in accordance with the tape speed.
