Title: Fitting ceramic cylinder with electrical part
Inventor: ENOMOTO AKIO
IPC: C04B37/02
Filed: 1989-03-16
Abstract: PURPOSE:To rapidly and surely carry out packing operation of adhesive and to fit a ceramic cylinder with an electric part by specifying an angle of inclination of an adhesive impregnating nozzle to gap between the ceramic cylinder and the electric part and an arranged position of a lower opening part of the nozzle. CONSTITUTION:A ceramic cylinder 41 and a metallic bolt 43 are slantingly held, namely a central shaft line L of cylindrical gap G is maintained in a slant state by a given angle alpha based on a perpendicular line H and an impregnating nozzle 33 of an adhesive feeder 32 is placed at a position corresponding to an uppermost position part of the cylindrical gap G. When an adhesive 44 is dropped from the impregnating nozzle 33 to the cylindrical gap G in this state, the adhesive 44 flows to the bottom of the cylindrical gap G and flows slantingly downward toward gap at the opposite side at the bottom as shown by an arrow. Consequently, since the adhesive 44 smoothly flows, no foams are entrained and since the liquid level of the adhesive 44 is downward moved approximately in parallel with a top face 41c of the cylindrical gas G and the liquid level of the adhesive 44 becomes almost the same level of the opening end face of the cylindrical gap G in a completed state of packing.

Title: Automatic rice polishing machine
Inventor: YAMAMOTO SOICHI
IPC: G07F17/00
Filed: 1993-03-23
Abstract: PURPOSE:To provide an automatic rice polishing machine which can prevent the faults caused by the jam of rice grains even when a beginner user of the machine forgets to measure the water of rice grains or when the rice grains whose water value are unknown are polished. CONSTITUTION:A hopper 14 contains a water measuring instrument 40. When the water value measured by the instrument 40 exceeds a prescribed level, an automatic rice polishing device is kept inactive regardless of operation of an operation switch. Therefore the operation of the rice polishing machine is inhibited in such a case where a beginner user forgets to measure the water of rice gains and uses the rice grains large water value or where the rice grains whose water value are unknown are polished. Thus it is possible to prevent the faults of the rice polishing device caused by the jam of rice grains.

Title: Ethanol reforming catalyst
Inventor: IMAI TETSUYA
IPC: B01J21/06
Filed: 1983-04-14
Abstract: PURPOSE:To obtain an ethanol reforming catalyst developing high activity and high selectivity at a low temp., free from carbon precipitation and having long life, by allowing a carrier containing rutile type titania to support one or more of a metal selected from a group consisting of platinum and Pd. CONSTITUTION:A rutile type titania-containing carrier is allowed to support one or more of a metal selected from a group consisting of platinum and Pd. The above mentioned carrier is easily obtained by baking anatase type titania or one prepared by coating alumina with titania at 600 deg.C or more. In the next step, the noble metal is supported by the carrier according to such a method that the carrier is immersed in an aqueous solution containing a compound, for example, a noble metal nitrate and, after baking, the baked supported carrier is further subjected to hydrogen reducing treatment. Thus obtained catalyst is excellent in reaction for reforming ethanol to gas containing H and CO and shows high activity and high selectivity at a low temp., for example, at 300 deg.C while prevented from carbon precipitation and develops long life.

Title: Thin-film green color el element
Inventor: TSURUMAKI NAOYA
IPC: G09F13/22
Filed: 1989-03-15
Abstract: PURPOSE:To permit substantial improvement in luminance by using ZnS, Tb and F for a luminous layer, and then composing it to specify Tb concentration as well as the ratio of F concentration to the F concentration respectively. CONSTITUTION:ZnS, Tb and F are used for a luminous layer whose composition is made such that Tb concentration may correspond to 0.5 to 2.0 at.%, and at the same time, the ratio of F concentration at.% to the Tb concentration at.% (the ratio of F/Tb) may correspond to a range within 0.2 and 0.9. The Tb is accordingly displaced to the Zn site of a luminous base material, so that the F is combined with the Tb in such a form that it may compensate for difference in the number of valence between the Tb and the Zn. Since the Zn has plus bivalence (Zn<2+>) while the Tb has plus trivalence (Tb<3+>), because of having a self-compensating effect upon doping, the amount of F may be safely made smaller than that of Tb. Thus, when the Tb and the F are respectively taken in, the luminous efficiency of the layer is heightened.

Title: Controlling method for wiper holding device
Inventor: SAWARA HIDESHI
IPC: B60S1/08
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To prevent a wiper blade and a lift-up mechanism from being interfered with each other and cause a damage by driving a lift-up operation, when it is detected that a wiper switch is turned off and a wiper blade is stopped at the initial stop position, and releasing the lift-up by switching on a wiper. SOLUTION: An operation timing control of a lift-up motor 214, has no relation with the on/off state of a wiper switch(WP) 326 and operation state of a wiper motor 110. However, it is preferable to confirm a signal from a cam switch 346, when the wiper arm is lifted up with an ignition switch (IG) 302 turned off. The lift-up operation is permitted based on the signal (turning on the cam switch 346) from an automatic fixed position stop device of the wiper arm so that wrong conditions such as performing of the lift-up operation during the moving of the wiper device can be surely prevented.
