Title: Cleaning method of semiconductor
Inventor: HARADA YOSHIHISA
IPC: B08B3/08
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To reduce iron concentration and carbon contamination of a substance surface and thereby to improve reliability, in SC-1 cleaning used for cleaning of a semiconductor substrate. SOLUTION: This method comprises a process of cleaning the surface of a semiconductor substrate by a semiconductor surface treating agent, of which the constituents are alkali, hydrogen peroxide and water and a process of rinsing the surface of the semiconductor substrate with ultrapure water after the cleaning, and a cleaning chemical to which a complexing agent containing one or more phosphonic acid group or salts thereof in the molecule is added in the range of 2.1E-5 to 4.2E-5 wt.% is used for at least one of the semiconductor surface treating agent and the ultrapure water for rinsing. According to this constitution, an improvement in reliability can be expected from the effect of removal of iron by the complexing agent, and moreover, lowering of the reliability due to carbon contamination is lessened. Therefore a cumulative fraction defective is made small, and improvement in the reliability can be realized in particular. Furthermore, reliability is improved, with regard to other chemicals and complexing agents, by providing the concentration of the complexing agent to be set within the range of 0.9-1.8 times that at the saturation temperature thereof.

Title: Gas flow valve
Inventor: SANAKA KOJI
IPC: A61B5/0235
Filed: 1989-03-29
Abstract: PURPOSE:To decrease the number of engagement parts of an opening part, and also, to stably allow gas to flow by constituting this valve so that a cavity formed between plural projecting parts in used as a gas flow port in the opening part, the opening part is brought to elastic deformation by pressure received by the pressure response surface, and the size of the gas flow port is varied. CONSTITUTION:A gas flow valve body 2 has an air passage along the axial direction, one end 2a of this body 2 is formed on the wedge-like pressure response surface, and its one end is formed so that a notch on a straight line, that is, a linear opening part 3 communicates with the air passage 1. Also, on the peripheral wall of the opening part of the other end face of this valve body, a pair of grooves 4 are formed linearly with the same notch direction as the linear opening part 3, and also, in a state that they are due down in the one end 2a direction of the valve body. Moreover, by a notch 7, the tip part of a sheet-like member 5 is divided into projecting parts 5a, 5b, and the notch 7 constitutes a cavity which comes to a gas flow port when the sheet-like member is installed in the valve body.

Title: Production of magneto-optical recording medium
Inventor: KIKUCHI KAZUHIKO
IPC: G11B11/105
Filed: 1989-03-29
Abstract: PURPOSE:To decrease the residual strains generated by formation of films on an underlying layer and protective layer by forcibly warping a substrate at a prescribed rate in the direction opposite to the direction of the composite membrane stress generated after lamination at the time of the film formation, then laminating the respective layers on the substrate. CONSTITUTION:This magneto-optical recording medium 5 is constituted by forming the underlying layer 6, magneto-optical recording layers 7, 8, and a protective layer 9 successively on the transparent substrate 1 by using an RF sputtering method. the substrate 1 is forcibly warped by the jigs for mounting the substrate and is fixed before the film formation and thereafter the film formation is executed. The direction and prescribed rate where and at which the substrate is warped are determined by the direction and magnitude of the compressive or tensile stress which is the composite membrane stress. The jigs are a means for forming a recessed surface to be used in the case in which the stress generated after the film formation is the compressive stress. This means consists of a substrate holder 2, an inner peripheral mask 3 and an outer peripheral mask 4. The substrate 1 is fixed to the substrate holder 2 and can be fixed in the state of warping the substrate 1 by the inner peripheral mask 3 and the outer peripheral mask 4. The rate of the warpage is decreased in this case. Since drawbacks that the films are crazed and cracked when applied with an external stress, such as temp. change, and the environmental resistance is poor, are eliminated in this way.

IPC: C12N15/09
Filed: 1995-03-31
Abstract: PURPOSE: To obtain a new gene coding for a mussel adhesive protein having a specific amino acid sequence and giving a protein useful e.g. for an adhesive exhibiting strong adhesive force, keeping the adhesive strength even in a wet environment and developing strong adhesive strength even in water. CONSTITUTION: This new mussel adhesive protein gene codes for a mussel adhesive protein having the amino acid sequence expressed by the formula or an amino acid sequence the same as the amino acid sequence expressed by the formula and is expected to be useful in a wide application range as a raw material for adhesives developing effective adhesive strength even by starting the bonding work under moist condition or in water. The gene can be produced by extracting an mRNA from the foot of a mussel by conventional method, preparing a mussel foot cDNA library from the cDNA by conventional method, screening the library by using a part of a Tyrrhenian mussel adhesive protein cDNA as a probe and recovering the DNA from the clone containing the mussel adhesive protein gene.

A through-hole is arranged for a slider 5 to insert the core 1. A recessed section is formed on the top end section of the through-hole, having an butting section 7, which abuts against the section 6 and conducts the positioning of the core 1, as a bottom surface. A coil 2 is inserted into the section 41 of the core 1, abutted against the section 43 of the core 1 to conduct the positioning and adhesively fixed.  Since no resin forming section is required for the positioning between the sections 42 and 42 and the disk 4, a gap 3 with respect to the opposing magneto-optical disk 4 is equally made by the section 41, 42 and 42.

IPC: B65H7/06
Filed: 1978-06-23
Abstract: PURPOSE: To realize a high-speed printing by controlling the running speed of the card according to the printing range of the card.  
     CONSTITUTION: A number of sheets of card to receive printing are stacked onto document holder 17 and then fed into constant speed roller 5 one by one. The printing is given to the card while being driven by roller 5. Which position on the card the printing is given to can be known previously by the order given from outside, and thus the card is run at a constant speed in regard of the print quality while the printing range reaches the printing mechanism. But in case the printing mechanism is about reaching the non-print part, the card is run in a high speed at that range. Then the card running is returned to the constant speed as soon as the printing mechanism reaches the print part, thus reducing the time required for printing of the card.
