Title: Vinyl chloride resin composition
Inventor: YAMAGUCHI NOBORU
IPC: C08K5/098
Filed: 1978-04-18
Abstract: PURPOSE: To prepare a rigid vinyl chloride resin composition giving a molded article with improved impact strength, by adding dibutyltin malate and dibasic zinc stearate to a rigid vinyl chloride resin composition.  
     CONSTITUTION: A rigid vinyl chloride resin composition containing 0.2W25 % of dibutyltin malate and 0.1W2.0 % of dibasic zinc stearate. Addition  of less than 0.1% of dibutylitin malate gives poor weatherability, and that of more than 25% increases the stickiness of the composition which results in the undesirably high torque in the molding machine. When the amount of the dibasic zinc stearate is lower than 0.1%, the heat stability of the composition becomes poor, and when it is higher than 2%, the composition becomes sticky.

Title: Manufacture of lambda/4 shift type diffraction grating
Inventor: FUJIWARA MASATOSHI
IPC: G02B5/18
Filed: 1989-02-27
Abstract: PURPOSE:To prevent the change of resist in properties so as to manufacture an excellent lambda/4 shift type diffraction grating by a method wherein a process in which an insulating film is formed on the resist is dispensed with. CONSTITUTION:A diffraction grating is formed of an insulating film 2 of SiNx on a substrate 1, a first resist 3 is applied onto the substrate 1 where the diffraction grating has been formed, and a part of the resist 3 is separated from the surface so as to expose a part of the surface of the diffraction grating of the insulating film 2. Then, a part of the diffraction grating whose length is nearly half that of the substrate 1 in a longitudinal direction of a resonator is removed, and then the substrate 1 is etched using the pattern of the resist 3 left unremoved in direct contact with the part where the diffraction grating has been removed. Then, the substrate 1 is etched using the pattern of the diffraction grating of the insulating film 2 on the rest part of the substrate 1 to form the diffraction grating. Therefore, a process, in which an insulating film is formed, is dispensed with. By this setup, resist is protected against degradation in properties and an excellent lambda/4 shift type diffraction grating can be manufactured.

Title: Radiation dose monitoring method for environment around nuclear power facilities
Inventor: KARASAWA HIDEAKI
IPC: G21C17/00
Filed: 1980-04-10
Abstract: PURPOSE:To discriminate facilities-contributing radiation dose with good accuracy by excluding the predetermined time before and after the signal detection of a prescribed meter, calculating the background line, subtracting the same from sampling data and determining the facilities-contributing radiation dose. CONSTITUTION:If the time within 5hr before the precipitation signal (b) by the precipitation meter is detected and the time within 7hr after the detection are defined as the exclusion period of the dose rate increased by precipitation, the average value S of the radiation dose rate is prevented from rising more than needed by the exclusion of the dose rate a2 increased by precipitation. Hence, if this average value S is subtracted as a background radiation dose rate from the sampling data, the facilities-contributing radiation doses X1, X2... are discriminated on the safe side with good accuracy, and the radiation dose of the environments around nuclear power facilities is monitored highly accurately.

Abstract: PROBLEM TO BE SOLVED: To miniature a cylinder, and to reduce the cost by improving the supporting force of a free bearing, and reducing the load on the cylinder. SOLUTION: A free bearing shaft 41 is integratedly provided on a lower part of a large number of free bearings 33 of worktables 23 of a plate machine. The free bearing shaft 41 is engaged with a vertically inclined guide groove 47 provided on an elevating/lowering guide body 49 through a lower guide roller 45. The elevating/lowering guide body 49 is reciprocated approximately in a horizontal direction by a hydraulic cylinder 53 on a linear guide 51 of a table frame 31, and then, the guide part is guided by the guide groove 47 on the elevating/lowering guide body 49, and the free bearing 33 is elevated/ lowered together with the free bearing shaft 41. Because the load of a work W is supported by the guide groove 47 of the elevating/lowering guide body 49 through the free bearing shaft 41 and the guide roller 45, the load of the work is not directly applied to a hydraulic cylinder 53.

Title: Pressure sensor
Inventor: SHOJI MASATO
IPC: G01L9/16
Filed: 1993-03-09
Abstract: PURPOSE:To suppress the deterioration of imide-based bonding agent in contact with water content and to prevent the peeling of amorphous magnetic alloy by mounting a yoke in the perfect tight contact with the main body of a sensor, and sealing dry air or resin into the yoke or evacuating the inside of the yoke. CONSTITUTION:Pressure is applied into a pressure chamber 2 through a pressure introducing port 2 so as to inflate a deforming part 4. Amorphous magnetic alloy 7, which is fixed to the surface of the part 4 with imide-based bonding agent, is deformed, and the permeability is changed. The change is detected with a pressure detecting coil 8 as the change in inductance. In a conventional pressure sensor, a yoke 11 is fastened to a main body 1 with screws. Therefore, the water content and humidity generated in a thermal shock test and a humidity test intrude into the inside through the gap of a screw, and the imide-based bonding agent is deteriorated. Thus, the amorphous magnetic alloy is peeled. Therefore, the main body 1 and the yoke 11 are brought into perfect contact with a welding part 14. Dry air 15 is further sealed into the tightly closed space formed of the main body 1 and the yoke 1. Thus, the intrusion of the water content and humidity is shut off. Therefore, the deterioration of the bonding agent is prevented, and the reliability can be improved.

Abstract: PURPOSE:To improve the accuracy reproducibility of a scaling instrument by fixing a scale to a member by a 2nd fixing means after fixing the fitting tool to a member by a 1st fixing means. CONSTITUTION:When the scale 1 is fitted to the member 3 such as a machine tone by using the fitting tool 2, the fitting tool 2 is clamped at a specific position of the member 3 with a fitting screw 9 and thus fixed. Then a fitting screw 8 is clamped to the member through a screw hole formed in the main part 2a of the fitting tool 2 and the fitting part of the scale 1 is held elastically with the pressure base parts of three leg parts 2b - 2d of the fitting tool 2 and the specific position of the member 3 to fix the scale 1 to the member 3. Thus, the deformation of the scale 1 when the scale 1 is fitted is eliminated and the accuracy reproducibility of the scaling instrument is improved.

Abstract: PROBLEM TO BE SOLVED: To prevent a charging gas from swelling at the jetting side in a product at the charging of the gas in the product and precisely mold a hollow product having a desired shape by a method wherein a gas showering member, which has an infinite number of minute axial through holes, is installed at the tip part of a charging rod. SOLUTION: When a gas is fed from a gas feeding source to a charging rod 11, to which a gas showering member 12, the gas reaches the gas showering member 12 through the introductory part and connecting passage of the charging rod 11 so as to pass through a large number of through holes in the gas showering member 12 in order to jet in a product. At this time, the gas is dispersed in a large number of minute sizes and jetted in the product under the dispersed state axially flowing along paths indicated with the arrow (b), resulting in preventing the gas from remarkably swelling outwards. In addition, since the lowering of the pressure loss of the gas can be suppressed as small as possible, the gas uniformly prevails in the product 14, resulting in partitioning a hollow part 14a into a desired shape.
