Title: Micro wave heating device
Inventor: MINAMITANI KOJIRO
IPC: H05B6/74
Filed: 1988-04-12
Abstract: PURPOSE:To prevent a micro wave oscillator from being subjected to great loading due to the repetation of on/off operations as well as to contrive to improve the life of the oscillator by letting the irradiation of micro waves to materials to be heated be temporarily suspended when micro wave discharge is induced in the materials to be heated. CONSTITUTION:In case of normal heating, micro waves oscillated by a micro wave oscillator 1 pass through a change-over shutter 3 in an open condition with loss hardly increased by way of an isolator 2 so as to be matched by an impedance matching unit 4 so that they are irradiated onto materials to be heated 5. When micro wave discharge is induced in the materials to be heated 5, the discharge is detected by a discharge detecting device 6 so as to let the change-over shutter 3 be changed over to a closed condition by the signal from the detecting device for letting micro waves from the micro wave oscillator 1 be reflected by the change-over shutter 3 so that the materials to be heated 5 will be free from the irradiation of micro waves so as to let the discharge disappear. This constitution thereby prevents the micro wave oscillator form being subjected to great loading when on/off operations are repeated, thereby making it possible to prevent the life of the oscillator from being shortened.

Title: Production of ceramic foamed body
Inventor: SATO SHUJI
IPC: C04B38/02
Filed: 1989-04-07
Abstract: PURPOSE:To obtain a ceramic foamed body having stable quality at relatively low temperature as well as high mechanical strength, by adding silicon carbide to the mixture of eruptions and CaO compound, molding the blend and foaming the moldings while heating. CONSTITUTION:A mixture consisting of (A) 60-90pts.wt. eruptions (e.g. volcanic ash such as silas or obsidian or volcanic rock such as andesite or basalt), (B) 40-10pts.wt. CaO compound such as limestone or lime, (C) silicon carbide as foaming agent, normally of <=1pts.wt. and (D) as necessary, melt auxiliary such as water glass or glass powder, normally of <=20pts.wt., preferably <=10pts. wt. is molded into a prescribed shape and then heat-foamed at 900-1,250 deg.C, preferably 1,100-1,250 deg.C to provide the ceramic foamed body. Since the resultant product is reduced in scattering of quality and foaming temperature is also low, energy cost in production is low. Further, the product is suitable as a heat insulator and refractory because of having about 900 deg.C heat resistance.

IPC: B23D33/02
Filed: 1986-04-18
Abstract: PURPOSE:To enable correction for deflections in pre-machining on a composite processing machine for plate materials by providing clamp devices on a secondary carriage for holding the plate material and so supporting the other clamp device as to be freely movable back and forth at least against one clamp device. CONSTITUTION:In a composite processing machine comprising a combination of a punching machine 7 and a cutting machine 9, for example, a primary carriage 21 transfers a plate material 'W' to the position of the punching machine 7 for a punching process. In this case, some deflections are generated on the plate material 'W'. Then, an image sensor 'K' measures at least two punching bore positions and on the basis of the measured values, a reference position for a cutting process is obtained. For the reference position, one of clamp devices 25 for a secondary carriage 23 is fixed and the other clamp device 25 is transferred back and forth by a distance corresponding to the plate deflections for carrying out the cutting process, thereby enabling the finish of the plate material 'W' to a predetermined size, the improvement of product quality and the rationalization of productivity.

Title: Coordinate input device
Inventor: SAKAGUCHI AKIHIKO
IPC: G06F3/03
Filed: 1990-04-03
Abstract: PURPOSE:To detect the pressure applied to the metallic core of an input pen contactlessly and also to optionally change the feeling to the writing pressure of the pen by attaining the constitution of a writing pressure detection means where a magneto-resistance element approaches to and breaks away from a permanent magnet when the writing pressure is applied to a resistor via the pen. CONSTITUTION:A metallic core 2c of an input pen 2 has a pen point 2d protruded from a pen holder 2a and is energized downward by a spring 4. A writing pressure detection means 3 contains a magneto-resistance element 31 fixed onto the upper inner wall of the penholder 2a and a permanent magnet 32 fixed to the upper end part of the core 2c respectively. The magnet 32 forms a magnetic circuit where a closed loop is formed between two magnets by a magnetic/metallic plate 32a. Then the element 31 moves in a leakage magnetic field 32b generated in the closed loop. Thus it is possible to eliminate the fluctuation of sensitivity due to the deterioration of a material and also to change the writing pressure, i.e., the handwriting feeling with replacement of the spring 4.

Title: Method and device for detecting breakage of metal strip
Inventor: MIYAKE MITSUHIRO
IPC: G01N27/20
Filed: 1990-04-03
Abstract: PURPOSE:To make an accurate judgement by measuring the plating current and the voltage at all times and judging that the metal strip breaks when the measured current value becomes smaller than a set current and the measured voltage becomes larger than a set voltage. CONSTITUTION:The set current value is stored previously in a current comparator 2 to which the measured current value is sent from an ammeter 4 all times and a comparator 2 calculates the large/small relation between the measured current value and set current value. Similarly, the set voltage value is stored previously in a voltage comparator 3 to which the measured voltage value is sent from a voltmeter 5 at all times and a comparator 3 calculates the large/ small relation between the measured value and set value. a judgement circuit 1 judges the breakage only when the measured current value is smaller than the set current value and the measured voltages value is larger than the set voltage value. The circuit 1 puts a breakage recognition relay 6 in line stopping operation almost at the same time according to the judgement result. Consequently, the line stops in an extremely short period to prevent an accident caused by the breakage of the metal strip.

Title: Horizontally opposed two-cylinder engine used as model
Inventor: SAITOU HAJIME
IPC: A63H29/00
Filed: 1983-05-23
Abstract: PURPOSE:To permit stable low-speed operation by increasing the capacity of one cylinder larger than that of the other cylinder, thus preventing the misfire on the other cylinder side in low-speed operation. CONSTITUTION:The captioned engine is equipped with the first and the second cylinders 1a and 1b, and is constituted so that the cylinder 1b is put into compression cycle when the cylinder 1a is in explosion cycle. In this case, the capacity of the cylinder 1a is set larger than that of the cylinder 1b. Therefore, when the cylinder 1a side is in explosion cycle and the cylinder 1b side is in compression cycle, the output of the cylinder 1a side is increased, and the load applied onto the piston 2a on the cylinder 1a side is reduced, and reduction of the speed of the piston 2a is prevented. Therefore, misfire is suppressed even in low-speed operation, and low-speed operation can be obtained stably.

Filed: 1989-04-07
Abstract: PURPOSE:To attain the diagnosis of a controller with high reliability by discriminating the faults of a common bus and/or a service bus from the faults of the function units. CONSTITUTION:A diagnostic function unit 21 is separated from a common bus 14 and a service bus 15 connected to the function units 17 - 20 by the switch means 23 - 27.
