Abstract: PURPOSE:To form a uniform catalyst layer by using a pore closing-type elastic material for absorbing the unevenness of a water-absorptive material which induces the unevenness of the obtained layer at the time of press-molding a sheet material for the catalyst layer formation while dehydration being carried out. CONSTITUTION:A sheet material 1 consisting of a carbon paper 2, a powder layer 3 containing a catalyst and adjacently formed on the carbon paper 2, and a filter 4 adjacently formed on the powder layer 3 is put between an upper die 5 for pressing and a lower die 6 for pressing and press-molding is carried out. A filter paper 7 for water absorption, which is a water-absorptive material, is put on the upper side of the material 1, and the filter paper 7 for water absorption and a pore closing-type elastic material 8 of sponge rubber, etc., are put in the lower side of the material 1 successively from the filter 4. When both dies 5, 6 for pressing are pressured under this condition, water in the sheet material 1 for the catalyst layer formation bleeds and the carbon paper 2, the powder layer 3, and the filter 4 of the material 1 are firmly joined each other and a catalyst layer with a prescribed strength is thus formed.

Title: Navigation apparatus
Inventor: OMURA HIROSHI
IPC: G01C21/00
Filed: 1996-09-17
Abstract: PROBLEM TO BE SOLVED: To provide a navigation apparatus by which the action intention, of an operator, generated suddenly during the guidance of a route to a first destination is satisfied, by which a second optimum destination is decided from a present position and by which a route up to the destination is retrieved and guided. SOLUTION: During the guidance of a route to a first destination, an operator wants not a specific destination but a detour by intending only a targeted action. In this case, a desired item from a plurality of items (B-1 to B-8) and retrieval conditions (A-1 to A-6) in a retrieval operation are selected by the operator. Then, a destination which belongs to the selected item and which is closest to the present position or a second destination which is estimated to be capable of being reached in a shortest time is retrieved on the basis of a designated retrieval condition so as to be guided. When the action is finished in a place at the detour, the guidance of the route to the first destination is resumed.

IPC: H01F17/00
Filed: 1990-09-13
Abstract: PURPOSE:To prevent a current to flow between both coils through the interwire distributed capacitance and improve the function as an inductor of common mode choke coil in the high frequency range through small floating capacitance generated as a distributed constant between both coils by making longer the interlayer distance between the internal conductor patterns of both coils at the intermediate portion of a coil. CONSTITUTION:The ferrite green sheets 2a, 1b,..., 2m, 1n from the first layer of coil 12 to the nth layer of coil 11 are alternately stacked by respectively inserting two sheets of through hole green sheets 3a to 3z. As explained above, at the intermediate layer, a long interlayer distance is taken by sandwiching total of three green sheets, a sheet of ferrite green sheet and two sheets of through hole green sheets 3a to 3z, between the internal conductor patterns 11b to 11n of coil 11 and the internal conductor patterns 12a to 12m of coil 12. Therefore, interwire distributed capacitance between coil 11 and coil 12 in the intermediate layer becomes very small.

Title: Line repeater
Inventor: OKADA SHIGEO
IPC: H04L7/02
Filed: 1985-10-31
Abstract: PURPOSE:To use plural clock frequencies by selecting one among plural tank elements and reproducing data with a timing signal passed through the selected tank element. CONSTITUTION:The output of an equalizing amplifier circuit 1 is sent to a regenerating circuit 2 and a timing circuit 3. When the passing frequency of a tank element 4 is f1 and the passing frequency of a tank element 5 is f2, a selecting circuit 6 detects levels from the tank elements 4 and 5 respectively to connect the tank element 4 in case of f1>f2 or the tank element 5 in case of f2>f1 to a limiter amplifier circuit 7. Therefore, when the clock frequency of a transmission line is f1, a signal flows through the tank element 4 all the time and when f2, the signal flows through the tank element all the time, so that equalization and regeneration are both performed normally regardless of whether the clock frequency of an input signal is f1 or f2.

Title: Power source for telephone exchange
Inventor: OKOCHI SADAO
IPC: H02M7/48
Filed: 1985-10-31
Abstract: PURPOSE:To reduce a power source capacity by converting and smoothing an input DC voltage into another voltage by high frequency switching, and converting to a low frequency AC by a second switching circuit. CONSTITUTION:A power source is composed of a DC/DC converter having a switching circuit S mainly including power transistor, a transformer T and a rectifying and smoothing circuit R, and a DC/AC inverter I including a transis tor without using a transformer. Thus, a DC power source E1 is converted by the circuit S to a high frequency rectangular AC voltage, transformed by the transformer T and then rectified and smoothed. This DC voltage is converted by an inverter I to a low frequency AC, and supplied to a load circuit Z. As a result, since the desired low frequency AC can be obtained by the inverter I formed of a transistor bridge without using the transformer thereby only a small size transformer T is necessitated to make small the size of the power source.

Title: Speed detector
Inventor: YASUI KATSUAKI
IPC: G01P3/488
Filed: 1994-10-11
Abstract: PURPOSE: To obtain a speed detector which has high sensitivity with a low-cost structure and is resistant against electromagnetic noise. CONSTITUTION: The pickup coil 7 of a sensor 1 is connected in series via a resistor 102 between the base and the collector of a transistor 101. An operational amplifier 104 for applying a predetermined voltage to the sensor 1 when the controller 2 is under predetermined conditions is provided. When an AC electromotive force Vi generated in the coil 7 falls within a predetermined range, the transistor 101 is always held in an active state, and so operated as to current amplify. Thus, even if the input impedance of the controller 2 is small, an input signal voltage can be obtained, and a high S/N ratio can be obtained against electromagnetic noise. The input impedance of the controller 2 can be reduced by the amplifier 104, and the sensitivity can be raised.

Filed: 1985-10-31
Abstract: PURPOSE:To avoid the cracking of semiconductor crystalline substrate improving the yield thereof by a method wherein semiconductor substrate is half-diced to form a mesa type structure in the cleavage direction of the semiconductor crystalline substrate. CONSTITUTION:Assuming the facial angle of a semiconductor to be 100 face, dicing lines 10 are formed within the range making an oblique angle of 2 deg.-20 deg. in the easily cracking cleavage direction 8 and the other cleavage direction 9 rectangular to the direction 8. The cracking ratio of semiconductor crystalline substrate is culminated because of the deflection angle theta of 0 deg. coinciding with the easily cracking direction while being subject to the deflection angle theta of 45 deg., the substrate is most hardly cracked. On the other hand, when the semiconductor substrate is divided into individual chip, the favorable chip shape can be assured subject to the deflection angle theta of 0 deg. in the easily cracking direction coinciding with the chip dividing direction. When the deflection angle theta is 2 deg.-20 deg., the movement of semiconductor crystalline substrate and the resultant improvement of yield can be assured without deteriorating the chip shape.
