Title: Perfume material
Inventor: MARUTA ATSUSHI
IPC: A61L9/01
Filed: 1989-03-10
Abstract: PURPOSE:To enable both the intensity of perfume and its durability to be controlled as required by letting perfume moisture absorbent coexist with perfume inclusion particles wherein perfume is included by cyclo-dextrin, and thereby letting them be formed into a powdery or tablet shape. CONSTITUTION:200g of perfume is directly added to 100g of beta-cyclo-dextrin saturated water solution. Then, the solution with perfume added is stirred so as to be mixed for two hours for letting them be filtered so that water as solvent is removed. And remaining moisture in sediment obtained wherein almost of water has been removed, is furthermore removed by means of a centrifugal separator, and then, the sediment is dried by a spray dryer and the like so that powdery perfume inclusion particles are obtained. When 15g of the aforesaid powdery perfume inclusion particles are mixed with 35g of calcium chloride as moisture absorbent, it can be confirmed that strong perfume can be consistently maintained at approximate same intensity for two weeks.

Title: Reel shaft driving device
Inventor: NAGATA YUUJI
IPC: B65H23/06
Filed: 1982-04-08
Abstract: PURPOSE:To simplify the structure to make it small-sized easily and to apply a back tension inexpensively and properly, by releasing the friction mechanism on the take-up reel side and operating only the friction mechanism on the supply reel side in accordance with the direction of tape running. CONSTITUTION:An idler 2 is provided on an idler arm 3 which is attached freely rotatably, and the idler 2 is floated in the direction of an arrow 5 by the rotation frictional force between the idler 2 and an idler bearing 4 and is brought into contact with a reel shaft 6. Since one end 10 of an arm 8 is used as the rotation shaft and the other end is half-fixed by a spring 9, the adhesive strength among a driving wheel 1, the idler 2, and the reel shaft 6 is enhanced to transmit the rotation efficiently. If the driving wheel 1 is rotated in the direction opposite to the direction of an arrow 7, the rotation of the driving wheel 1 is transmitted to a reel shaft 6' in the reverse direction. Pad arms 12 and 12' are interlocked with the motion of the idler arm 3 to slide pads 13 and 13' only on the reel shaft which is in the supply state, thus obtaining the back tension.

Title: Thermal battery
IPC: H01M6/36
Filed: 1992-03-17
Abstract: PURPOSE:To improve battery insulation resistance in vibration and shock resistance by providing a polyimide film on the outside of a heat insulating material laid around the external surface of a generation section and the inside of a battery sealing vessel for maintaining insulation property between the vessel and the generation section. CONSTITUTION:The ends of ignition input terminals 1 fitted to the base 3a of a battery sealing vessel 3 are provided with a fusehead 4, and a heat insulating material 5 is so mounted as to surround the fusehead 4. In operating a battery, ignition current is caused to flow through a pair of the terminals 1 from the outside of a battery and the fusehead 4 is actuated, thereby supplying power from a generation section 8 to the outside of the battery via output terminals 2. In this case, the temperature of the section 8 rises to a few hundred centigrade degrees and, therefore, heat resistant materials 5 and 7 are so laid as to surround the section 8 for shutting out temperature. In this constitution, a polyimide film 6 as the insulation 5 is laid on the outside of the heat insulating material 7 for maintaining insulation property between the vessel 3 and the section 8. In this case, the thickness of the film 6 is between 20 and 50 microns. According to this construction, the thickness of the film 6 can be decreased to a value between 1/2 and 1/5 of 100 microns as general mica thickness.

Filed: 1986-03-18
Abstract: PURPOSE:To enable a diaphragm portion with a prescribed thickness to be formed by a simple operation without increasing operating processes by performing an etching for enabling the thickness of the diaphragm portion to be visually confirmed on the same surface side and at the same time as the formation of the diaphragm portion. CONSTITUTION:Silicon oxide films 2 and 3 are formed in lamination on both surfaces of a substrate 1 having a plane (100). A diaphragm portion forming window 4 and rectangular first, second and third windows 5a, 5b and 5c, respectively, are formed in the silicon oxide film 3 on the reverse side at the same time. The substrate 1 is anisotropically etched at its exposed portions in the windows 4, the first, second and third windows 5a, 5b and 5c, respectively, and etching depths are determined by the size of the windows. When the recesses formed by the windows reach prescribed depths, the bottoms of the recesses become rectilinear and an etching does not progress over the prescribed depths. During this etching process, a diaphragm portion 7 is formed on the portion etched through the window 4. Thus, by visually confirming the configuration of the bottom of the etched portion, the etching of the diaphragm portion is terminated.

Abstract: PURPOSE:To suppress the occurrence of a trailing phenomenon or the like to improve the quality of a reproduced picture by erasing a direct radiation part of a radiograph accumulated and recorded on an accumulating phosphor sheet and reading the picture thereafter to obtain a picture signal. CONSTITUTION:A direct radiation part 2b is recognized, and the direct radiation part 2b of a radiograph 2 accumulated and recorded on the accumulating phosphor sheet 1 is erased, and thereafter, the accumulating phosphor sheet 1 is scanned with exciting light and the stimulated luminous light is read to obtain the picture signal.

The operation to discharge the radiation energy stored on the accumulating phosphor sheet is called 'erasing'. Thus, an influence of the direct radiation part having a considerable great influence of flare and afterglow is eliminated, and the picture signal where this influence is reduced is obtained, and the occurrence of a trailing phenomenon or the like on the reproduced picture is suppressed to improve the picture quality.
