Title: Manufacture of oxygen sensor for internal combustion engine
Inventor: ORIMO YASUSHI
IPC: G01N27/409
Filed: 1990-03-24
Abstract: PURPOSE:To suppress the release at a cut surface or the cracks of an element, in forming an oxygen sensor, by humidifying the laminated sheet body of an oxygen ion conductive solid electrolyte before cutting the same. CONSTITUTION:Slots 5, reference electrodes 6 an counter electrodes 7 are formed on plate bodies 1 - 4 formed by the extrusion molding of a kneaded mixture of zirconia and water and, thereafter, the plate bodies 1 - 4 are laminated and integrated. For example, the laminated one is allowed to stand in a thermostatic tank for a predetermined time to be huimidified. In this case, humidification is pref. performed for 1.5 hr under such a condition that temp. is 25 deg.C and humidity is 85% in order to prevent the adhesion of waterdrops to the surfaces of the plate bodies 1 - 4 and to obtain desired effect within the shortest time. After the humidification is completed, the plate bodies 1 - 4 are cut along cutting lines L1- L3 and the cut sensor element parts are baked for a predetermined time to be formed into zirconia ceramic. Since the plate bodies 1 - 4 are cut after humidification as mentioned above, the hardness of the plate bodies 1 - 4 at the time of cutting lowers and the generation of release or the breakage of an element can be suppressed and the time required in a visual observation process is also shortened.

Inventor: KURAHASHI MASAHIRO
IPC: B65H9/00
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To previously prevent unnecessary noise from generating, and temperature of a drive source from excessively rising, by setting a movement control quantity for returning a sensor standbying on a standby position to a reference position smaller than a movement control quantity for previously moving the sensor to the reference position, and enabling an operating time of a sensor driving means to be shortened when the sensor standbying on the standby position is returned to the reference position. SOLUTION: A sensor 47 is previously positioned on a reference position PB, and the sensor 47 is moved from the reference position PB to a standby position PW previously set according to the size of a print paper sheet 26. The sensor 47 is moved from the standby position PW to the print paper sheet 26 carried in the side of the standby position PW so as to detect the side end of the print paper sheet 26, and the sensor 47 is let stand by on the standby position PW until the next print paper sheet 26 is carried in the side of the standby position PW. Accompanying completion of detection of the side end position of the print paper sheet 26, the sensor 47 is returned to the reference position PB.  A movement control quantity for returning the sensor 47 standbying on the standby position PW to the reference position Ps is set smaller than a movement control quantity for previously moving the sensor 47 to the reference position PB.

Title: Method and apparatus for separating substance mixture of liquid phase
Inventor: DEIITERU DEITSUSERUBETSUKU
IPC: C02F1/14
Filed: 1981-05-20
Abstract: In a process for separating mixtures of matter in the liquid phase and a device suitable therefor, liquid (12) absorbs heat during its passage through a first cavity (3), said heat having been generated during the condensation yielding the condensate (13) at the upper wall portion (5) of the first cavity. The thus preheated liquid is passed to a third cavity (9), the upper wall portion (10) of which is liquid-tight and gas-tight and absorbs the thermal radiation (11). Part of the liquid further heated by said process evaporates and penetrates in vapor form through the liquid-tight, steam-permeable upper wall portion (8) of the third cavity (9) into a second cavity (6), the upper wall portion (8) of which is one and the same as the lower wall portion (9) of the third cavity. This steam condenses under the cooling action of the first cavity (3). The condensate (13) so formed is withdrawn from the second cavity. The cavities (1) and (3) are advantageously contained in double fabrics provided with adequate coatings and the two fabrics of which are spaced apart by means of spacers in the form of filaments.

IPC: G09B29/10
Filed: 1998-03-24
Abstract: PROBLEM TO BE SOLVED: To retrieve a proper route according to weight loaded on a vehicle. SOLUTION: In a navigation device 1, a route to a destination set by a destination setting device 11 is retrieved based on map data stored in a road information storing device 3 by a controller 4. The route selected as the result of the normal shortest route retrieval is stored in a shortest route retrieval register 8. When weight detected by a load weight detecting device 5 is a prescribed value or more, the controller 4 operates a steep slope road exclusion route retrieval by excluding a road having ascending slope, which is a prescribed value or more as an object to be retrieved by referring to road slope information 6 from the map data, and stores the result in a steep slope road exclusion route retrieval register 10.  Then, weighted route retrieval is operated by considering weight and slope by referring to a constant slope weighting table 7, and the retrieved result is stored in a weighted route retrieval register 9. The stored contents are compared, and the smaller stored content is selected as the result of the route retrieval.
