Title: Batch annealing method for high carbon steel
Inventor: ISHIBASHI GENICHI
IPC: C23C8/22
Filed: 1992-12-17
Abstract: PURPOSE:To prevent decarburization on the surface of a steel sheet in batch annealing for high carbon steel. CONSTITUTION:As an atmospheric gas in an inner cover of an annealing furnace, hydrogen with a high concn. is used, furthermore, in the case the coldest point temp. of a coil reaches >=400 deg.C in the process of temp. rising, the atmospheric gas is fed with gaseous components such as carbon monoxide, methane, ethane, propane and butane carburizing the surface of the steel strip and, in the case the coldest point temp. of the coil reaches <400 deg.C in the process of cooling, the carburizing gaseous components are stopped. In this way, decarburized layers on the surface layer of the steel strip are obviated.

Title: Image processing unit and its method
Inventor: UEHARA RYUHEI
IPC: H04N19/00
Filed: 1993-12-28
Abstract: PURPOSE:To allow a receiver side to recognize an outline of an image even when the entire image data cannot be transferred to the receiver. CONSTITUTION:Upon the receipt of a transfer request by a control section 106, a coordinate calculation section 103 calculates a coordinate of an picture element being an object of transfer. The calculation is made by dividing an image into four in a shape of 'cross in square' and obtaining the sequence of coordinates of picture elements to be transferred as to each small picture. The calculated result is extracts sequentially in the order of an upper left image, a lower right image, an upper right image and a lower left image as to each image and the transfer sequence of picture elements of the entire image is decided. The method is recurrently applied to each of 4-division pictures to decide the transfer sequence of picture elements. Thus, the picture elements are sequenced impartially as to the entire image and even when the transfer is interrupted on the way, an outline of the entire image is transferred.

Inventor: CHATTHA MOHINDER S
IPC: F01N3/24
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To provide an ideal NOx trap material cheaper than a NOx trap material such as Pt-BaO/alumina catalyst and durable. SOLUTION: The exhaust gas generated from an internal combustion engine is treated by periodically changing a ratio of air to fuel in the exhaust gas entering the trap between a lean operation and a rich operation so that the nitrogen oxide trap is installed in an exhaust passage, the nitrogen oxides are adsorbed during the lean operation and the nitrogen oxides are released during the rich operation. The trap consists of a porous carrier being substantially γalumina, and 0.5-4 wt.% Pt, based on the weight of the carrier, supported on the carrier. The released nitrogen oxides enable to be converted into N2 and O2 on novel metal by reduction substance such as hydrocarbon present in the exhaust gas.

IPC: B65H20/20
Filed: 1991-11-27
Abstract: PURPOSE:To provide a printer device, which admits setting of a slip simply and which can make sensing of a jam. CONSTITUTION:Each tractor 6 includes a tractor door 3 to hold a slip inserted, a reflex type sensor 2 appended to the door 3 and sensing whether any slip exists, a tractor pin 4 to transport the slip, and a tractor belt 5. The sensor 2 is installed in such a position as capable of simultaneous sensing of a left-end and a right-end sprocket hole when the sheet is fed normally. The tractor mechanism part has two of such tractors 6 on the left and the right each equipped with the mentioned components. When both sensors sense sprocket holes, it is judged that the sheet is fed normally, and if one of them senses sprocket hole, it is judged as under jamming. Accordingly the slip can be set in the tractors automatically only by inserting along guides. It is also possible to sense jam.

Title: Static ram
Inventor: KADOTA JUNJI
IPC: G11C29/04
Filed: 1989-12-26
Abstract: PURPOSE:To detect a relief address by raising the potential of one selected word line when word lines in a normal word line group are selected and raising the potential of two redundant word lines when redundant word lines are selected. CONSTITUTION:A redundant word line driving circuit consists of an inverter to which a redundant memory cell activating signal is inputted. Consequently, when an external input address matches a relief address, the potentials of two redundant word lines centering on a word line driving circuit rise. When the external input address does not match the relief address, on the other hand, the potential of one normal word line rises. Therefore, when the relief address is inputted, the total of penetration currents is about twice as large as that in the potential rise of normal word lines. Consequently, a relief address detecting circuit, etc., need not be added and penetration currents flowing through memory cells are detected to detect the relief address from outside and the chip area is reduced.

Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to detect surely whether an electronic part is put in a correct position in a feeder or not, and improve efficiency in mounting the electronic part. SOLUTION: An electronic part 22 fed from a feeder 11 is sucked by a suction head 13 and moved and mounted on a circuit board. A distance sensor 34 mounted on the suction head 13 scans the feeder part.

The image of the feeding position of the feeder 11 is picked up by an imaging camera 32. The position of the suction head 13 is compensated adequately on the basis of the image. In these steps, a suction nozzle 23 can suck a correct part accurately, and thereby efficiency in mounting an electronic part can be improved.
