Title: Drying treatment method for glass fiber strand or direct roving
Inventor: YAMANAKA KIYOUICHI
IPC: C03B37/10
Filed: 1978-06-23
Abstract: PURPOSE: To prevent accumulation of solid components in greige goods to both  surfaces of a rolled strand or direct roving in the roll axial core direction and to  prevent occurrence of unevenness in strength and color due to the accumulation, in  manufacture of products, by covering the surfaces with water absorbing substance layers prior to drying.  
     CONSTITUTION: Upper surface 1A and under surface 1B of rolled direct roving 1 are wholly covered with porous gas and water permeable plates 3A, 3B provided with internal water absorbing substance layers 2A, 2B. A number of convered rolls A to be dried are heat dried with hot air while being moved in a drying furnace. As water contained in greige goods is evaporated, solid components move forming high concn. parts k 1 , k 2  around both inside and outside 1a 1 , 1a 2 . As water is evaporated from upper and under surfaces 1A, 1B, the solid components are absorbed in layers 2A, 2B. After drying, plates 3A, 3B provided with layers 2A, 2B are detached, and parts k 1 , k 2  are drawn out and removed. Layers 2A, 2B can be used repeatedly until their water absorbing properties are deteriorated. A rolled strand can be treated similarly.

Title: Manufacture of metallic calcium
Inventor: SAKAGAMI KENICHI
IPC: C22B26/20
Filed: 1979-06-20
Abstract: PURPOSE: To economically manufacture Ca at a high reduction rate by making the grain size of CaO larger than that of a conventional method and briquetting the CaO together with Al of a specified grain size when the CaO is reduced to Ca with the Al by a vacuum hot reduction distilling method.  
     CONSTITUTION: CaO and Al are mixed and briquetted, and the CaO is reduced to Ca with the Al by a vacuum hot reduction distilling method. At this time, the grain size of the CaO is adjusted to 1W3mm which is larger than that of a conventional method, and the grain size of the Al to 0.2W4mm. The blending ratio of them is calculated according to the stoichiometric amounts of equation I. The reduction is carried out under the following conditions: a vacuum degree of 0.03mmHg or less, a temp of 1,150W1,200°C, and a time of severalW10hr. Metallic Ca is obtd. at a reduction rate of 90% or more. Since the grain size of the CaO is not made smaller than the necessary size, CaO crushing time and equipment are saved. In place of the Al an Al alloy may be used.

Title: Piston for internal combustion engine and manufacture thereof
Inventor: ONISHI SHIGERU
IPC: F02F3/00
Filed: 1995-02-25
Abstract: PURPOSE: To perform control of the temperature of a piston by a method wherein structure is formed in such a manner that a part or the whole of a combustion chamber volume part is cast insertingly with a material different from a piston material surrounding and having high thermal conductivity, in an internal combustion engine wherein the combustion chamber volume part is built at the upper area of a piston. CONSTITUTION: In a so-called re-entrant-shaped piston wherein a combustion cavity part is formed in a piston and the opening part of the cavity forms throttle structure, the piston forms double structure wherein the peripheral area of the combustion chamber of a piston is surrounded with copper or a copper alloy (a high thermal conduction material) 4 having high thermal conductivity so that a piston temperature is controllable. In a combustion chamber part, the high thermal conduction material 4 is exposed and covered with an aluminum or a cast steel piston material 3 for protection so that oxidation melt loss is prevented from incurring.  This constitution rapidly absorbs the heat of a high temperature part by the high thermal conduction material 4 serving as a core part and rapidly transits and disperses heat to a low temperature part by utilizing the high thermal conductivity to cool a piston temperature.

Title: Temperature measuring method
Inventor: NAKAHIRA MIZUHO
IPC: G01K11/00
Filed: 1980-06-09
Abstract: PURPOSE:To perform temperature measurement in a low temperature range simply and accurately by utilizing the fact that the transmittivity of crystalline optical fiber to ultraviolet and visible rays depends on temperature. CONSTITUTION:Crystalline optical fiber is set at a position where temperature is to be measured and ultraviolet and visible rays are passed through it. The temperature is measured by transmittivity of the rays. For instance, a crystalline optical fiber 1 in which the core is AgCl (100%) and the clad is AgCl (92%)-AgBr (7%) is wound round a part 2 to be measured. Light of 0.42 micron in wavelength is passed to this from a laser emitter 3 and the transmittivity is measured with a light receiver 4 consisting of a photoelectric multiplier. In this case, for instance, transmittivity of 0, 6.2 and 81% are obtained at 198K, 89K and 3K respectively, and thus an accurate temperature measurement is made possible over a wide range in a low temperature range. Crystals of various halogenides can be used as material for optical fiber.

Abstract: PURPOSE:To prevent the dispersion of product characteristics and the damage of an outer casing member and to facilitate the vibration of non-linear characteristics by providing a second elastic member having elastic modulus smaller than a first elastic member which is formed in one body by pouring rubber material into a gap between the inner periphery of the outer casing member and the periphery of the first elastic member. CONSTITUTION:Rubber material is poured between the periphery of an inner casing member 12 and the inner periphery of a metallic mold, and adhesive agent is applied to the periphery of the member 12, and first elastic member 13 and the member 12 adhere mutually in one body at the same time as a curing process has been done. Next, the elastic member 13 is formed in a fixed size by its constricting after the curing process, and in this case, the periphery of the elastic member 13 is formed with two recesses 16a, 16b. Next fixed preliminary compression is given to the elastic member 13 after it is pressed into an outer casing member 11, and the recesses 16a, 16b therefore form a pair of gaps 14a, 14b together with the inner periphery of the member 11. Second elastic members 15a, 15b are also formed in a pair by pouring urethane foam resin having a fixed expansion ratio into the gaps 14a, 14b to prevent damage caused by the entering of a small stone or the like into gaps between the members.

Abstract: PURPOSE:To prevent an end mill from being damaged, by providing the tip of a stylus with the same form as that of the end mill and making the outside diameter of the main part of the stylus much larger than that of the main part of the end mill not to cut a steep slope. CONSTITUTION:The tip 11 of a stylus S1, which has the same form as the tip of an end mill E, is brought into contact with the horizontal or near horizontal surface of a model M to cut a workpiece W according to the form of the model. The lower end of the main part 13 of the stylus S1, which has a much larger outside diameter than the end mill E, is brought into contact with the slope of the model M which has an inclination of 60 deg.. At that time, the tip 11 of the stylus is separated from the model to put the end mill out of contact with the workpiece W not to cut it, so that the end mill is protected from damage. To cut the workpiece W whose steep slope is not yet cut, profiling is performed by a stylus of the same form as the end mill E. Complicated work for preventing the end mill from being damaged is thus made needless.
