Inventor: HORUSUTO GIRUHAUSU
IPC: F27B14/06
Filed: 1992-07-16
Abstract: PURPOSE: To prevent transmission of sound by uncouplting a furnace platform sonically from the furnace body in an untilted normal position. CONSTITUTION: A furnace platform 3 disposed proximately above a tiltable furnace body 1 is uncoupled completely therefrom the in a normal position. The rear section thereof is secured to a platform 4 and to the opposite sides of the furnace body 1 above the side wall 5 of furnace box. At least on two side parts, the furnace body 1 is covered with the furnace box and the rear part is covered with the platform 4.

Title: Electrooptic switch
Inventor: MIKAMI KAZUO
IPC: G02F1/31
Filed: 1981-11-25
Abstract: PURPOSE:To obtain a compact, inexpensive electrooptic switch by providing a couple of electrode on a surface of photoelectric anisotropic crystal, connecting  at least two optical fibers to one end surface crossing the surface at right  angles, and providing on the other surface a concave mirror which guides polarized components of light from one optical fiber to the other optical fiber. CONSTITUTION:On a surface of anisotropic dielectric crystal 1 made of PbMoO4 having electrooptic effect, a couple of linear electrodes 2 are provided; and optical fibers 11-13 are connected through an SELFOC lens 4 to one end surface crossing the surface at right angles, and concave mirrors 21-23 are formed in the other end surface. While no AC voltage is applied to the electrodes 2, light projected from the optical fiber 11 for incident travels straight in the crystal 1 through the lens 4, and is reflected by the mirror 23 to illuminate the optical fiber 13. When a voltage is applied, an electric field E is produced in the crystal 1 and two polarized component of the incident light by birefringence are reflected by the concave mirrors 21 and 22 to enter the optical fiber 12. Thus, a compact, inexpensive switch is obtained.

Title: Bag refuse
Inventor: TAKEMURA SHINJI
IPC: B65F1/00
Filed: 1995-06-20
Abstract: PURPOSE: To throw away things without polluting a garbage box by fixing a string or a rubber-form thing to the mouth of a refuse bag in advance, and laying it on the inside of the refuse box as it is, and fixing the string or the rubber-form thing to the brim of the barbage box. CONSTITUTION: First, a string 2 or a rubber-form thing is so fixed as not to slide to the mouth of a vinyl bag 3. Second, it is laid on the inside of a garbage box 4 as it is, and the string 2 or the rubber-form thing is fixed to the brim of the bargage box 4. Hereby, the box whereon the refuse bag is laid never slides because the brim of the garbage box 4 is fixed by the string 2 or the rubber, so the garbage box 4 is not polluted, either. Moreover, by overlaying the refuse bag on the inside of the garbage box 4, the mouth of the garbage box 4 opens completely, so the refuse can be dumped easily.

Title: Small-sized three-group zoom lens
Inventor: OGATA YASUSHI
IPC: G02B13/18
Filed: 1990-07-18
Abstract: PURPOSE:To decrease the telephoto ratio at the wide-angle end to <=1.2 by finding combinational conditions of the focal length and image formation magnification of respective groups of the lens. CONSTITUTION:The zoom lens consists of a 1st group G1 with positive refracting power, a 2nd group G2 with positive refracting power, and a 3rd group G3 with negative refracting power. The overall length of the lens can be shortened by setting the composite power of the telephoto types G1 and G2 and the power of the G3 large. For the purpose, two conditions 0.5<¦f3/fw¦<0.9 and 1.3<beta3w<2.0 are required, where fw is the focal length of the whole system at the wide-angle end, f2 and f3 are the focal lengths of the 2nd group and 3rd group, and beta3w is the image formation magnification of the 3rd group. When, however, a movement distance for power variation becomes large, a camera main body can not be reduced in thickness, so the movement quantities of the groups need to be reduced for size reduction, so 0.5<¦f3/fw¦<1.3 should hold. Consequently, the lens system is reduced in size by satisfying those conditions.

Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To easily form a titanium oxide film with certainty by coating a base material with titanium oxide sol and then irradiating the coated surface, in this state or after drying, with microwaves. SOLUTION: As the base material, any material, organic and inorganic alike, such as glass, ceramics, wood, bamboo, and activated carbon, suffices as long as it has a surface shape to which titanium oxide sol can adhere.

The microwave used here is ordinarily an electromagnetic wave of 300 MHz to 30 GHz frequency, preferably, that of 245 MHz used for an electronic oven for domestic use. As the crystal form of the titanium oxide film to be formed, anatase with high performance as photocatalyst is preferred. The resultant titanium oxide film is porous and increased in specific surface area and can adsorb the organic compounds contaminating the environment and decompose them by sunlight, etc.
