Title: Formation of photoresist film
Inventor: TAGUCHI TAKASHI
IPC: H01L21/027
Filed: 1989-07-05
Abstract: PURPOSE:To sufficiently remove a solvent in a resist film in a short period by applying heat treatment wherein temperature of a photoresist mask is raised stepwise at the time of prebaking in the case of forming the photoresist mask. CONSTITUTION:At the time of prebaking after a photoresist is spread, the prebaking is performed by dividing the process into two or more multistages. The processing temperature is changed stepwise. In this case, for example, the fist stage of the prebaking is performed at 90 deg.C or less, and the subsequent stage of the prebaking is performed at a temperature higher than the first stage. By performing the multistage prebaking in this manner, solvent scarcely remains in the thickness direction of the resist film nonuniformly. Further, processing time of baking can be reduced, so that thermosensitivity caused by prebaking can be decreased. Thereby the solvent in the resist film can be sufficiently removed in a short period.

IPC: B01J20/22
Filed: 1989-07-05
Abstract: PURPOSE: To selectively remove the chemical species from the liquid by allowing the liquid to contact with an element having a ligand for the species on its surface. CONSTITUTION: In the removing method of the species from the liquid, the liquid is brought into contact with the element having the ligand for the species on its surface.

In the selective removal of the species from the liquid, for example, in order to attain the removal of a specified protein from a mixture of proteins, the polymer must be minimum in non/specific adsorption on the element. An activated or activatable polymer is a hydrophilic polymer preferably and a chemical group giving the hydrophilic property is a hydroxyl group, etc.

Title: Objective lens magnification decision device for optical equipment
Inventor: DOI HIROMASA
IPC: G02B7/38
Filed: 1989-07-04
Abstract: PURPOSE:To device the magnification of an objective automatically by providing a means which detects the quantity of Z-axial movement from the rising to the falling of a focusing point signal. CONSTITUTION:A sensor signal outputted from a subtracter 9 is divided by the output of an adder through a divider 22 to obtain a focusing signal DELTAS. The focusing signal DELTAS outputted by the divider 22 is compared by a comparator 24 with a threshold value Vref<->. Assuming that the distance from a focusing point is long when the focusing signal DELTAS is negative and too short when positive, the comparator 24 detects the threshold value Vref<-> twice (P1 and P2) if the distance to the focusing point decreases through the search operation of an automatic focusing mechanism. An objective decision device 26, therefore, decides the power of the objective 4 from the quantity DELTAZ of Z-axial movement from the point P1 to the point P2. Thus, the magnification of the objective 4 is decided automatically.

Title: Cryogenic refrigerating machine
Inventor: NARASAKI KATSUHIRO
IPC: F25B25/00
Filed: 1990-07-02
Abstract: PURPOSE:To realize a highly efficient and a highly reliable cryogenic refrigerating system by a method wherein Gifford Macmaphon refrigerating cycle is combined with a magnetic refrigerating cycle and single circulating loop employing helium gas of common operating fluid is constituted. CONSTITUTION:When a high pressure valve 3 is opened, a low pressure valve 4 is closed and a magnetic field, applied on a cold heat accumulator 10A and generated by superconductive magnets 26, is reduced, the temperature of the cold heat accumulator 10A is reduced by magnetic refrigerating effect. Simultaneously, high-pressure helium gas flows from a compressor 2 into a cylinder 6 whereby a pressure in a room temperature space 16 above a displacer 8 increases from a low pressure PL to a high pressure PH. Next, when the displacer 7 is moved upward, helium gas in the room temperature space 16 dissipates heat through cold heat accumulators 8A, 9B, 10A and is cooled, then, moves to a chamber 17, an expansion chamber 18 and another expansion chamber 19. When the magnetic field, applied on the cold heat accumulator 10A, is reduced further, the helium gas, passing through the cold heat accumulator 10A through a pipeline 24, is cooled further more, then, is discharged out of the cold heat accumulator 10A and absorbs heat from a refrigerating load 29 in the part of a pipeline 25, then, enters the expansion chamber 19.

Abstract: PURPOSE:To granulate ungranulated coal and granulated coal of a size smaller than 0.5mm. to a required size, by deashing dust coal in slurry and granulating it into a 1st batch of granulated coal for recovery and granulating ungranulated coal and small-sized granulated coal from a waste water tank into a 2nd batch of granulated coal. CONSTITUTION:A conditioned slurry is fed into a high-speed stirring tank 3 together with a binder emulsion B. After deashing, the slurry is led into a low- speed stirring tank 4 for agitation and formation of agranules in the require size of 0.5mm. or larger. The 1st batch of granulated coal of a required size is separated for recovery in a 1st shaking sieve 5 and waste water is discharged down into a 1st waste water receiving tank 6. As the amt. of slurry of ungranulated coal increases and reaches level H.L. in the receiving tank 6, the capacity of a pump 7 is equalized to the total of slurry and emulsion B fed into the tank 3. The ungranulated coal is intermittently formed into the 2nd batch of granulated coal in a granulation tank 8 and separated for recover in a 2nd shaking sieve 5a.

Filed: 1984-08-20
Abstract: PURPOSE:To output a characteristic pattern for about every T/n time from a characteristic extracting circuit though a processing time of one processing unit is T by storing a program of the same processing in a program memory of a characteristic extracting circuit. CONSTITUTION:A processing unit 5 cuts out a character pattern for one character each from a video memory 10 and sends it to a data line 35 at the prescribed interval.

Consequently, it takes Tsec for a characteristic pattern of the character pattern to be is first sent from the processing unit 6a, and after that, the characteristic pattern of a next character pattern is sent from the processing unit 6b after 1/n sec, and thesame way, the pattern is sent from 6c. Consequently, an extracting characteristic pattern is outputted from the circuit 2 every T/n sec.

Filed: 1980-12-10
Abstract: PURPOSE:To improve the abrasion resistance and the airtightness of scroll members by applying surface treatment layers on the surfaces of scroll members. CONSTITUTION:In a scroll fluid machine, a fixed scroll 1 and a rotary scroll 2, which cnsist of mirror plate sections 1a, 2a and lap sections 1b, 2b are arranged to engage each other at the lap sections 1b, 2b. Surface treatment layers 10, 11, 12 are applied on the surfaces of the lap groove sections 1c, 2c; the lap sections 1b, 2b; the mirror plate sections 1a, 2a of both scrolls 1, 2. These surface layers 10 through 12 are formed by treatment of sulphurizing and nitriding for cast iron and steel, and anodic oxidation and Tefoln soaking for aluminum alloy. When the fixed scroll 1 and the rotary scroll 2 are pressed each other in the axial direction, soft portions with high fitness on the surface treatment layers 10 through 12 covering all surfaces fit each other, forming a sealed space 9. Therefore, the coarseness of the surfaces is minimized, and the airtightness is improved.

Title: Production of magnetic recording medium
Inventor: KIMURA YOSHITAKA
IPC: G11B5/84
Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To enable production of a magnetic recording medium having few defects by controlling the contact angle of the substrate surface with pure water after surface treatment within a specified range. SOLUTION: The surface state of a substrate after surface treatment relates to data defects of a magnetic recording medium, and especially among properties of the surface state, the contact angle with pure water largely relates to defects. The contact angle is preferably <=85 deg.. Since the contact angle is influenced by the cleaning state of the surface, the cleaning degree is increased by using a detergent having high cleaning performance, by increasing the temp. of the cleaning liquid, by extending the cleaning time, by cleaning while scrubbing, etc., in order to control the contact angle to 85 deg.. If the contact angle is >85 deg., the substrate surface is easily dried before the film forming process after the surface treatment and contamination deposits and fixed on the dried part. This causes peeling after a film is formed.  Therefore, by controlling the contact angle to <=85 deg., the substrate is prevented from drying during carrying, and moreover, a magnetic recording medium having little defects can be obtd.
