Title: Tubular bulb
Inventor: KAWAKATSU AKIRA
IPC: H01K1/32
Filed: 1992-12-28
Abstract: PURPOSE:To prevent deterioration of optical transmittance so as to enhance the efficiency of light by alternately stacking high and low refractive index layers each made from a metal oxide on the surface of a bulb, and interposing a metal nitride layer between the interfaces of the layers. CONSTITUTION:A high refractive index layer 2H made from titanium oxide is formed over the outer surface of a bulb 1, a metal nitride layer 2M made from silicon nitride is formed over the layer 2H, and a silicon dioxide layer 2L whose refractive index is lower than that of the layer 2H is formed over the layer 2M. Further, a layer 2M is formed over the layer 2L and a layer 2H is formed thereover and 10 to 30 layers are repeatedly stacked one atop another in that order to form an optical interference film 2. With the film 2 thus formed over the outer surface of the bulb 1, the visible range of light emitted from a coil is transmitted through the film 2 and radiated out of the bulb, whereas the infrared range of the light is reflected at the film 2 and returned to heat the coil to enhance heating efficiency. Therefore, deterioration of optical transmittance due to multilayer formation can be prevented and the efficiency of light enhanced.

IPC: H01M10/05
Filed: 1992-12-28
Abstract: PURPOSE:To prevent deterioration, etc., of battery performance that could be caused by damage to an electrode and a short circuit caused in a non-circular spiral electrode body or by unevenness of the tension of the electrode by providing a hollow, metallic pipe in the center through hole portion of the spiral electrode body.

When the roundness of the circular electrode body 2 is decreased by pressing, curvature of less than a certain amount, formed by the outer periphery of the pipe 1, is secured even at the innermost peripheral portion of the electrode body 2, so an internal short circuit that could be caused by damage to the electrode or by the absence of the electrode can be prevented. Also the tension of the inner peripheral portion of the electrode is prevented from becoming uneven and even tension is maintained so that battery reaction is accelerated, and that discharge characteristics, and cycle characteristics in the case of a secondary battery, can be enhanced. Further, a pipe 1 at the center portion of a non-circular spiral electrode body can be used directly as a current collector core, so manufacturing processes can be simplified.

IPC: C04B20/06
Filed: 1992-12-28
Abstract: PURPOSE:To improve the strength of artificial lightweight aggregate by including plural bubbles composed mostly of spheres having the same shapes in artificial lightweight aggregate. CONSTITUTION:This artificial lightweight aggregate contains plural bubbles 2, wherein the most part of the bubbles 2 are spheres 2A having the same shapes. The ratio of the (minor axis)/(major axis) of the bubble is preferably >=0.70. A strength required for artificial lightweight aggregate can be attained by this composition. The adjustment of the particle size distributions of the raw material particles and the foaming agent particles may be carried out by using precision sieves, however, it is sufficient for the industrial production to adjust the passing diameter ratio to >=1/4 by using conventional crusher, air classifier, etc. The shape of the bubble can be varied to spherical shape by the adjustment of the particle size distribution of the raw material, however, the bubble shape is controllable by other methods such as the control of baking temperature, heating rate, retention time in the furnace, baking atmosphere (e.g. oxygen concentration), etc.

Title: Abrasive grain tool and manufacture thereof
Inventor: ENOMOTO TOSHIYUKI
IPC: B24D3/34
Filed: 1998-12-08
Abstract: PROBLEM TO BE SOLVED: To uniformly and finely disperse abrasive grains and microcapsules utilizing electrophoretic phenomenon to enable ultraprecise polishing to be executed by actually preventing the abrasive grains from coagulating, in an abrasive grain layer formed out of the abrasive grains and the microcapsules. SOLUTION: Silica is, for example selected as abrasive grain, water-based acrylresin is selected as water soluble macromolecule (binder), and they are mixed at a fixed addition rate. Positive and negative electrodes are arranged in such suspension, and voltage is impressed between both electrodes to execute electrophoresis. An abrasive grain layer is formed around the positive electrode, and after cutting out the abrasive grain layer from the electrode and reshaping it into a grinding tool pellet, it is dried to obtain a grinding tool pellet for grinding/polishing. In the abrasive grain pellet, microcapsules and abrasive grains do not actually coagulate, and uniformly disperse.  Consequently, in addition to improve working rate and surface roughness by addition of the microcapsules, occurrence of scratch on the worked face can be dissolved, and hence ultra-precise grinding/polishing face can be insured.
