Title: Insulated gate type fet
Inventor: MIKOSHIBA KEIMEI
IPC: H01L29/78
Filed: 1983-06-22
Abstract: PURPOSE:To attain a short channel without keeping a deep junction region too much close to a channel region, by forming a tapered side wall sufficiently thick. CONSTITUTION:The etching of an oxide film over the entire surface of a substrate by a reactive ion etching method enables to form the side wall 8 in the side surface of a polycrystalline Si. At this time, when the etching is carried out with the substrate inclined by an angle theta to the direction 10 of etchant infiltration and while it is rotated around the center axis 12, the thickness of the wall 8 increases because of being etched with taper in the shaded part. As a result, the deep junction region 9 comes off from the channel region, therefore punch through becomes difficult to occur, and the step part of the Si becomes gentle, resulting in the facilitation of fine Al wiring.

Title: Electronic oven
Inventor: ISHIBURO KATSUMI
IPC: F24C7/02
Filed: 1990-04-27
Abstract: PURPOSE:To permit a user to confirm the accurate accumulated oscillating time of a magnetron at any time by counting the oscillating time of the magnetron using a time counting means to be added to a readout data, and writing the addition result data in a storage means via a data transfer means. CONSTITUTION:When a microcomputer 3 enters a cooking start command through a key input unit 5, it reads out accumulated oscillating time data from an external memory 7 to be stored into its own counter. Then the microcomputer judges whether a magnetron 2 is turned on or not, and when it judges the magnetron is turned on, it counts up accumulated oscillating time data obtained from the counter so as to add up the accumulated oscillating time thereof. When the microcomputer judges the magnetron is turned off on the other hand, it judges whether an electronic oven finishes cooking a food or not. And only when the microcomputer judges the electronic oven has finished cooking the food, it writes the accumulated oscillating time data (total time) obtained as a result being added up by the counter in the external memory 7. The user of the electronic oven thus can recognize accurately the total operating time of the magnetron 2 via the key input unit 5.

IPC: C21D8/12
Filed: 1987-05-11
Abstract: PURPOSE:To manufacture a grain-oriented silicon steel sheet excellent in magnetic flux density, by hot- and cold-rolling a silicon-steel slab to the final sheet thickness, by applying decarburization and primary recrystallization annealing, and then by subjecting the above-mentioned sheet to secondary recrystallization annealing by carrying out temp. gradient-applying treatment. CONSTITUTION:A silicon-steel slab is hot-rolled into a hot-rolled plate of 2.2mm thickness and then subjected to the first cold rolling and rolled until 0.60mm thickness is reached. Subsequently, at the time of the second cold rolling after process annealing, the above sheet is cold-rolled to 0.20mm thickness by means of rolls in which surface roughness is continuously changed from one end to the other end in a length direction. Successively, this sheet is subjected to primary recrystallization annealing which doubles as decarburization in a wet hydrogen atmosphere, and then, an annealing and separation agent composed principally of MgO is applied to the above sheet, which is subjected to secondary recrystallization annealing in an N2 atmosphere. At this time, prior to secondary recrystallization annealing, the steel sheet is subjected to gradient annealing where the initial temp. of the secondary recrystallization has a temp. gradient of >=2 deg.C per cm extending over the width direction or longitudinal direction of the steel sheet and then to purification annealing.

Title: Adaptive reception circuit
Inventor: ONIYANAGI HIROYUKI
IPC: H03H17/02
Filed: 1993-05-14
Abstract: PURPOSE:To stably and quickly adapt a circuit to various variances of the transmission line characteristic by providing a signal conversion part which converts a main signal X into a prescribed level. CONSTITUTION:A signal conversion part 1 converts the main signal X into a rough signal X' having a prescribed level roughness, and this conversion is so performed that the amplitude of the rough signal X' is shorter than that of the main signal X in the case of the main signal X having a prescribed amplitude or longer. An adaptive transversal filter 4 consists of an FIR filter 2 which generates an equalized output Y by convolutional operation between the main signal X and a tap coefficient A and a tap coefficient update part 3 which obtains the tap coefficient A minimizing an error signal (e) based on the rough signal X' and the error signal (e). Thus, the signal level of the rough signal X' is suppressed even the signal level of the main signal X is deviated from a normal code point area and is abnormally raised by the disturbance like fading, and therefore, disorder of the tap coefficient vector A is reduced, and recovery to convergence is quickly performed.

Title: Position detecting passage sensor
Inventor: WATANABE SATOSHI
IPC: G01C15/00
Filed: 1999-03-16
Abstract: PROBLEM TO BE SOLVED: To enable a passage sensor to detect the passing position of a passing object without arranging sensors on the top side, bottom side, right side, and left side by detecting the passing object by means of two or more light projecting and receiving units and calculating the passing position from the intersection of lines respectively drawn from the positions of the units at detecting angles. SOLUTION: Light projecting and receiving units 11 are vertically arranged at a prescribed interval. A regressive reflecting plate 12 is commonly used for the units 11. When no passing object 13 exists, the light beams projected from the first and second light projecting and receiving units 11 for scanning are reflected by the reflecting plate 10 and the reflected light beams are continuously received by means of the units 11, but, when a passing object 13 exists in the scanning area, the light beam projected from the first unit 11 is intercepted by the object 13 at an angle θ1 and no reflected light beam returns to the first unit 11. Similarly, the light beam projected from the second unit 11 is intercepted by the object 13 at another angle θ2 and no reflected light beam returns to the second unit 11.  Therefore, when lines are respectively drawn from the positions of the units 11 at the angles θ1 and θ2, the position of the object 13 can be calculated as the intersection of the lines.
