Title: Internal tooth forming device
Inventor: ARAI SHINJI
IPC: B21H5/02
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To reduce cost of a forming device and an internal tooth member, and get the forming device and the internal tooth member smaller in size. SOLUTION: The device has a mandrel 78 a fixed member for fastening a raw material at a front edge of the mandrel 78, and a forming roller for deforming the raw material by pressing it against the mandrel 78. The mandrel 78 is composed of a main element part 16 and a ring 17 arranged adjoining to the main element 16 wherein the main element is equipped with a tooth die part 79 composed of plural grooves 21, both ends of which are kept opened. A peripheral edge part of a front end face of the ring is slanted backward. Since the mandrel 78 can be manufactured by a through forming method grinding processing, the cost of the forming device and the internal tooth member can be reduced. When a material in the groove 21 is pressed against the peripheral edge part, since a pressing stress is generated inside the ring 17, no chipping occurs at the peripheral end part.

Abstract: PURPOSE:To increase light emitting intensity by forming an light emitting layer portion, having a band gap smaller than that of a non-light emitting layer portion adjacent to each conductive layer, at that portion of an intrinsie semiconductor layer remote from first and second conductive layers that pinch the semiconductor layer. CONSTITUTION:An light emitting element L consists of a transparent conductive layer 2 formed on a glass substrate 1, a p-type a-SiC layer 3 and an Ag electrode 6a formed on the conductive layer 2, a light emitting i-type a-SiC layer 4, n-type a-SiC layer 5 and an Ag electrode 6b formed on the layer 3 in succession. The i-type a-SiC layer 4 includes a light emitting portion 4c formed between two adjacent non-light emitting layer portions 4a and 4b and provided with a band gap smaller than those of the other layer portions. Because the light emitting layer portion 4c has smaller band gap than the other layer portions 4a and 4b and is located close to the p-type a-SiC layer 3, light emitting intensity can be improved.

Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To provide a mixer system capable of preventing spilling out a material after crushing, by engaging a vessel and a vessel bed by an engaging means comprising a stopper bar vertically movable by dead weight and an engaging hole member. SOLUTION: A mill vessel 1 is fixed in a mill vessel bed 3 by rotating a male screw part 2 toward fastening direction to be screwed into a female screw part 4. Since the mill vessel 1 is located in upward direction of gravity and the mill vessel bed in downward direction of gravity respectively, the tip of a stopper bar member 23 is inserted into an engaging hole 25. Inconvenience such as the mill vessel 1 coming off the mill vessel bed and spilling out a material 12 contained inside and dirtying surrounding is prevented by this condition. When a crushed material 12 contained in the mill vessel is to be taken out, the mill vessel 1 and the mill vessel bed 3 integrated together is rotated to set the mill vessel bed 3 in upward direction of gravity.  Thereby, since the tip of the stopper bar member 23 is released from an engagement 25, when the mill vessel bed 3 is rotated toward the releasing direction, the mill vessel comes off from the mill vessel bed 3 and the retained crushed material 12 can be taken out.

Title: Back track system with designation of plural evaluating orders
Inventor: AORI YOSHIZOU
IPC: G06F9/44
Filed: 1987-09-30
Abstract: PURPOSE:To solve the complicated problems with high efficiency by replacing the priority order with another to continue the inference in case the search fails with said priority. CONSTITUTION:When it is decided that the inference fails with execution of a rule conclusion part 8, a back track is pointed for the inference by a back track execution propriety deciding means 9. Then a pair selection means 3 for gathering to be evaluated selects a data/rule gathering pair having a higher priority degree following the data/rule gathering pair presently evaluated. Thus the processing is started again at and after the evaluation of the inference subject given from a data/rule extracting means 4. As a result, the inference is quickly and automatically carried out in a substitute evaluating order even though the inference carried out in a certain evaluating order fails.

Title: Dielectric filter
Inventor: FUJIKAWA MAKOTO
IPC: H01P1/202
Filed: 1994-10-12
Abstract: PURPOSE: To obtain the dielectric filter with excellent yield in which the effect of contraction of a volume is reduced when a dielectric material is baked by covering an inner face or the inner side face and a bottom face of a non- throughhole formed to a forming body made of a dielectric material with an electrode. CONSTITUTION: An inner side face or the inner side face and a bottom face of a non-throughhole 2 made from an upper face to a lower face of a forming body 1 and of a non-throughhole 3 made from the lower side to the upper side with a dielectric material 9 inbetween are covered by electrodes 5, 6 to form an independent resonator. Then the electrode 5 and an input electrode 7, and the electrode 6 and an output electrode 8 or the electrodes 5, 6 form a coupling capacitor via the dielectric material 9, they act respectively like a λ/4 resonator to form 2-stages of dielectric filters.  As a result, since the characteristic of the filters of the 2-stages mainly depends on the distance between the bottom faces of the two non-throughholes 2, 3, the dielectric filter hardly receives the contraction of a volume when the dielectric body is baked and the dielectric filter with excellent yield is obtained.

Title: Upper-and-lower-display swtiching device for cumulative display on preset counter
Inventor: ISHII HIDEO
IPC: G01F15/075
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To easily display upper display digits of numerical value even if the number of digits of flow rate exceeding the number of lower display digits on a total display portion is measured. SOLUTION: A plurality of photoelectric switches comprising a pair of a light emitting element 22 and a light receiving element 23 for receiving its signal are disposed on a switch mounting plate in this upper-and-lower-display switching device for accumulated display. Each of these photoelectric switches corresponds to a processing function. In these photoelectric switches, when a shift switch 24 and a total operating switch 21 are pressed, a display on lower display digits of a total display portion 11 is switched to a display on upper display digits. Thus, easy changeover of the display to the display on the upper display digits is allowed simply by operating an operating switch, and the flow rate can be instantly read. Even if the number of display digits is increased, the entire device needs not to be enlarged to compact the device.

Title: Fuel cell power generation plant
Inventor: YAJIMA TORU
IPC: H01M8/04
Filed: 1994-10-12
Abstract: PURPOSE: To suppress drop of the voltage likely to be generated by a steep drop of the temp. and provide a battery with a long life without impairing the safety by supplying a heated inert gas to a fuel cell in the event of emergency stop, and thereby preventing steep drop of the temp. at the time of stopping. CONSTITUTION: When a fuel cell 10 goes in an emergency stop. a selector valve 14 is turned to the inert gas 17 side, and the flow of combustion gas generated by a fuel reformer 13 is stopped. On the other hand, the combustion continues at a burner 15, and a heated inert gas is supplied to the fuel cell 10 to keep its temp. constant. When the combustion at the burner 15 is stopped, the temp. in the reformer 13 sinks gradually, and in association therewith the temp. of the inert gas also sinks, and the temp. of the fuel cell falls slowly at a rate as not causing drop of the voltage. This prevents voltage drop likely generated by a steep drop of the temp. to permit prolongation of the life of a power generation device. and also the reliability can be enhanced.
