Title: Aluminum alloy foil for electrolytic capacitor electrode
Inventor: SAKAGUCHI MASASHI
IPC: H01G9/04
Filed: 1987-04-23
Abstract: PURPOSE:To use even an aluminum foil having a comparatively large quantity of Fe and Si as an electrolytic capacitor electrode foil without causing the lowering of electrostatic capacitance and the increase of leakage current by incorporating a proper quantity of fine deposited Fe or deposited Si into the aluminum foil. CONSTITUTION:The purity of aluminum is or exceeds 99.9%, and 0.0015-0.01 wt.% Fe and 0.0015-0.015 wt.% Si are contained. The quantity of precipitation of at least one of Fe or Si exceeds 10% of content thereof, and is regulated within a range of 70% or less. It is preferable that a deposit having size of 1mum or less be included in the amount larger than 50% of the whole. Accordingly, an electrode foil having the same performance as an aluminum foil having high purity is available despite its low purity.

Title: Optical fiber type humidity sensor
Inventor: TSUTSUI TERUAKI
IPC: G01N21/17
Filed: 1987-04-23
Abstract: PURPOSE:To obtain a highly stable temperature sensor, by providing a porous surface layer comprising fine particles of SiO2 on the surface of a quartz core, using said layer as a surface-treated optical fiber core, and using the core itself as a temperature sensor. CONSTITUTION:In a surface-treated optical fiber core 7, light from a light source 9 is reflected and propagated in a quartz core 11 and reaches a photoreceptor 10. Since moisture 13 is adsorbed in the porous surface, leaking and scattering of the light occur at an interface when the light hits the interface between the quartz core 11 or the SiO2 particles 12 and the adsorbed moisture 13. Thus optical loss is yielded. The value of the optical loss is proportional to the amount of the adsorbed moisture. As a result, the intensity of the light, which is transmitted through the surface-treated optical fiber core 7, is changed in proportion to the relative temperature of gas in a measuring region.

IPC: H01J1/30
Filed: 1996-04-23
Abstract: PROBLEM TO BE SOLVED: To simplify structure, wherein a cathode and an electron source are integrated, by providing a high-concentration impurity region in a diamond thin coat, to make this region double as the function of the cathode. SOLUTION: A surface electron source and cathode 2, composed of material having negative affinity, is formed on a first substrate plate 1, and an anode 4 and phosphor coats 5, 6, and 7 are formed on a second substrate 3. The substrates 1 and 3 are oppositely constituted via a spacer 8, and the peripheral parts of both substrates 1 and 3 are sealed by a frit glass, to retain a portion, nipped with both substrates 1 and 3, in a vacuum. Also, a matrix, constituted of the cathode 2 and the anode 4, is multiplexly driven, to give an electric potential difference between the cathode 2 and the anode 4 at every picture element, to display two-dimensional information. Since an electron source doubles as the cathode, the electron source and the cathode are not needed to be provided separately, thereby the structure of them extremely being simplified.

Title: Tunnel transistor
Inventor: YAMADA TAKAHIRO
IPC: H01L29/739
Filed: 1984-05-18
Abstract: PURPOSE:To operate at a high speed by interposing the low impurity density region of a noncontracted semiconductor between a high impurity density region and a contracted semiconductor, and controlling the tunnel effect of the boundary between the contracted semiconductor and the noncontracted semiconductor by the low impurity density region of the noncontracted semiconductor, thereby moving carrier with nondiffusion. CONSTITUTION:In a structure that a low density region (n<->) 105 of noncontracted state is interposed between a high impurity (p<++>) region 101 of contracted state and a high density impurity (n<+>) region 102 of noncontracted state, the region 101 forms a source region, the region 102 forms a drain region, and the region 105 forms a gate region. When a voltage V2 is applied between the source and the drain and a voltage V1 is applied between the gate electrodes 103 formed through an insulating film 104, a tunnel barrier is formed at the boundary between the region 101 and the region 105, the electron of valency electron band of the region 101 is introduced by the tunnel effect to the region 105 to run in nondiffusion, and again arrived at the region 102 by the tunnel effect. Since the electron runs in nondiffusion, the deceleration effect is removed to operate at a high speed.

Title: Lost foam pattern casting method
Inventor: MATSUSHITA MASAYUKI
IPC: B22C9/04
Filed: 1988-04-25
Abstract: PURPOSE:To prevent agglomeration of sands caused by solidification of liquid monomer and to reutilize the molding and by embedding a lost foam pattern into the molding sand to form the mold, making dilute condition of oxygen in the mold and again taking the oxygen in the mold after pouring molten metal. CONSTITUTION:The lost foam pattern 3 is laid on bed sand in the flask 1 and the molding sand 7 is packed to form the mold. The upper part of the flask 1 is sealed with a cover body 8 and the air in the flask 1 is sucked through the pressure-reducing chamber 2 to make the dilute condition for the oxygen. The molten metal 9 is poured into the pattern body 4 through a runner 6 and a runner gate 5. As the oxygen in the mold is dilute-state, combustion is restrained and the lost foam pattern is thermal- decomposed and made to liquid monomer 10 and extruded into the sand grains for the molding sand 7. The molten metal 9 is filled up in place of the lost foam pattern 3. After pouring, the cover body 8 is taken out to make oxygen-rich state in the mold. As the liquid monomer 10 extruded into the molding sand 7 is high temp., at the tie of bringing into contact with the oxygen, it becomes gas into the sand grains, and is burnt with the residual heat in the mold and removed from the molding sand 7.

Abstract: PURPOSE:To offer the bedding drier which can clean simply a dead body and dung of a tick, etc., without necessitating a cleaner specially, does not give a dirty sense nor an unpleasant sense at the time of using the drier, and can be operated actually in a clean state. CONSTITUTION:The bedding drier 100 is provided with a dust collecting part 9 for containing a tick dead body, etc., and functions as a cleaner by changing an attachment after drying of bedding is finished. In this invention, a bypass passage 8 for feeding out air sucked from a suction port 3, from a feed-out port without allowing it to pass through the dust collecting part 9 is provided, and at the time of drying bedding, this bypass passage is used. Since air which does not pass through the dust collecting part 9 is fed to bedding, it is clean actually, and a dirty sense is not given to a user. At the time of regular use, the dust collecting part is attachable and detachable, so it is also possible to remove the dust collecting part concerned at the time of drying bedding, and it is also possible to improve a use sense by drying bedding by air which does not pass through the dust collecting part.

Title: Final picture reproduction system for disk reproducing device
Inventor: YASUDA SHIGERU
IPC: H04N5/93
Filed: 1987-04-24
Abstract: PURPOSE:To reproduce pictures produced subsequent to intermission without spoiling the continuity of a story by means of simple operation by reproducing a recording information in a recording position that precedes the position of the intermission in the recording sequence when picture reproduction follows the intermission. CONSTITUTION:In the event of a need to intermit the viewing of a movie, etc., if a memory instructional key is operated, an address data representing a second recording position that precedes a first recording position where a picture when the intermission is recorded in the recording sequence by a distance corresponding to a prescribed time T1, is written in a last memory where it is held. If a user turns on the power source again and operates a last memory key, a disk is loaded, the second recording position is searched, and the tape- playing operation is started from this position. So by making the prescribed time T1 such a time that is sufficient for the user to remember the story, the reproduction consequent to the picture at the time of intermission comes to be such one as hot impairing the continuity of the story in the user's mind.
