IPC: A61P35/00
Filed: 1982-08-28
Abstract: PURPOSE:To obtain the titled substance useful as an antitumor agent with little side effects, by extracting an animal cartilage with an aqueous solvent, precipitating the resultant extract with a hydrophilic organic solvent, and separating a fraction of a molecular weight within a specific range having a collagenase inhibitory activity. CONSTITUTION:An animal cartilage, preferably a bovine fetal cartilage, is extracted with an aqueous solvent and then precipitated with a hydrophilic organic solvent, e.g. acetone, to separate a fraction having 20,000-300,000 molecular weight and a collagence inhibitory activity by the separating method with a membrane and give the aimed antitumor active substance. The resultant antitumor active substance can be purified if desired by the conventional purifying means for proteins, e.g. dialytic method, freeze-dried and preserved. The resultant freeze-dried substance is a water-soluble light yellow powder having 6-7pH in an aqueous solution thereof. The substance has little side effects because the substance is derived from the living body, and made from the animal cartilage available in large amounts as a starting material. Therefore, the practicability as a carcinostatic agent can be expected.

Abstract: PURPOSE:To enable in-line measurement even in multicomponent mixed liquid by irradiating sample liquid with exciting light, further irradiating sample with exciting light having wavelength absorbed by the object material of measurement in an excited state, and measuring the quantity of the absorption of the exciting light. CONSTITUTION:The exciting light 21 from a pulse laser light source 1 shoe pulse intervals are controlled 7 is branched 9, and one is guided to a light source intensity detector 5 and the other is guided to a sample cell 3 to project on the sample 11. The exciting light 22 from a CW laser light source 2 is also guided to a light source intensity detector 6 and the sample 11 similarly. Then materials which do not transit an excited state from a base state with the exciting light 21 are excluded from a detection range, and materials which do not transit the excited state of further upper level with the exciting light 22 are also excluded from the detection range. Consequently, the concentration of a desired object material can be measured. Further, when there is a coexistent material which can not separated, variation in the absorption of the exciting light 22 with lapse of time is measured to find the light absorption quantity in a time area wherein the influence of the coexistent material is little, and the absorption intensity based upon only the contribution of the material to be measured is measured to determine the concentration of the object material.

IPC: B60L9/16
Filed: 1978-12-06
Abstract: PURPOSE: To make the tractive force uniform by driving one of two induction motors, which are mechanically connected to each other, by means of a common inverter and by driving the other by means of another power converter controlled by an output current of the inverter.  
     CONSTITUTION: Each of the motor units 4A, 4B is made up such that both driving shafts of the main induction motor (IM) 41a, 41b and the auxiliary induction motor 42a, 42b are mechanically connected to each other. Power variable voltage and frequency is fed from the inverter to the main IM and from the auxiliary converter to the auxiliary IM. The auxiliary converter compares a signal of the current detector 8A, 8B with a reference signal and gives a fixed control signal to the auxiliary  IM. In this way, the scattering of the tractive force, which is caused by the difference between both diameters of the wheels, can be compensated to make the tractive force uniform.

Title: Semiconductor device
Inventor: MORI KOZO
IPC: H01L21/3205
Filed: 1990-06-08
Abstract: PURPOSE:To reduce silicon segregation of a contact, and to decrease contact resistance by opening a contact hole through an insulation film, and implanting P-type or N-type ion of impurities through the contact hole, and then forming an aluminum alloy film containing silicon on the insulation film. CONSTITUTION:An opening pattern of a photo-resist is formed only in the region to be implanted by P-type ion in the photo-resist processing. P-type ion of impurities is induced by ion implantation to high-resistance polysilicon in the contact holes of 8, 9, and 10, with the photo-resist ad a silicon oxide film as a mask. Then, the photo-resist is removed, and the ion implanted layer is activated by lamp annealing. Accordingly, resistance of the second layer polysilicon in the contact holes can be lowered. As a result, contact resistance can be reduced when high-resistance polysilicon is used as a resistor, and high- resistance characteristics as a resistor is stabilized.

Title: Method of molding hollow ball of synthetic resin
Inventor: ISHIKAWA MAKOTO
IPC: B29C31/00
Filed: 1978-12-07
Abstract: PURPOSE: To obtain a ball having a high physical strength and a high elastic force by molding a synthetic resin with a gas-generating material contained therein, whereby a ball which has no air injection port and which is free from air leak is produced.  
     CONSTITUTION: A material (for example, diazo compound or sodium bicarbonate) which generates a gas at a temperature at which a ball is molded is mixed in paste of a ball-molding synthetic resin, such as vinyl chloride. The resulting paste is placed in a hot rotary mold so as to be heated. The paste is thus extended along the inner surface of the mold as the paste is expanded by a gas generated by the gas- generating material contained therein, to obtain an object ball. The gas-generating material may not be directly mixed in the paste; it may be put in a thermally meltable bag, which is then placed in a mold. Ball-molding paste consisting of a synthetic resin only may be thereafter placed in the mold to subject it to a molding operation.

Abstract: PURPOSE: To roughen the base body metal surface with Ni powder, etc., and make lower the BaO content in the oxide layer, which comes into contact with the base body metal surface, than the BaO content at the top surface, thereby supressing the growth of the intermediate layer and retaining stable electron emitting characteristics over a long period.  
     CONSTITUTION: Powder of Ni, etc., is applied by spraying, etc., over the base body metal surface and baked, so that base body surface will be roughened by protrusions of Ni. Then as the carbonate layer 15 which is to come into contact with base body metal 21, composite salt consisting, say, of SrCO 3  and CaCO 3  is sprayed; and over the carbonate layer, composite salt consisting of BaCO 3 , SrCO 3  and CaCO 3  is sprayed in order to obtain excellent thermal electron emitting characteristics. Then the sprayed base body is decomposed by heating in vacuum to form a solid solution of alkaline earth metal. In this way, the BaO content is made lower at the portion which is in contact with base body metal than at the top surface, thereby making it possible to obtain excellent thermal electron emitting characteristics which are stable over a long period.
