Title: Formation of coating film
Inventor: KATOU SHINYA
IPC: G03F1/54
Filed: 1979-08-14
Abstract: PURPOSE:To improve a pattern on a semiconducter substrate by a method wherein the formation of a coating film of a metal or a metal compound on a surface of the substrate is carried out repeatedly over plural numbers while a coated amount per a time unit is increased or decreased. CONSTITUTION:By carrying out the formation of the coating film by accumulation on the surface of the substrate intermittently or carrying out the increase or the decrease of a coating amount per a time unit repeatedly over plural times, irregularities of a peripheral edge portion of a coated pattern are reduced. For example, in a vacuum vapor depositing apparatus containing the substrate 2 maintained by a rotating holder 3 in a chamber 1 thereof, when a evaporation source 4 of metal chromium is heated and an evaporated amount is reached to 60Angstrom /min. constantly, a shutter 5 is opened for 2min. to deposit a chromium layer with thickness of 120Angstrom  and, subsequently, the shutter 5 is closed for several ten sec., thereafter opened again to carry out the deposition. By repeating this procedure five times, a chromium layer with thickness of 600Angstrom  is deposited. Subsequently, the deposition is carried out similarly 5 times by using chromium oxide to deposit a 60Angstrom layer thereof. Next, when a mask pattern is fabricated by wet etching, irregularities on a peripheral edge surface are reduced and a sharp edge surface for superior to a conventional one is obtained.

Title: Heat resistant film excellent in dimensional stability and manufacture thereof
Inventor: OKU MITSUO
IPC: B32B27/36
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To obtain an enough antistatic effect and a hardened coat surface strength by a method wherein a resin coat, which contains the specified amount of thermosetting or photosetting hardened matter and has the specified thickness to the thickness of a biaxially stretched polyester film, is formed on one side of the biaxially stretched polyester film having the specified thickness. SOLUTION: Since if the thickness of a biaxially stretched polyester film is below 10 μm, a problem on its strength develops and if its thickness exceeds 40 μm, a problem on its cost develops, its thickness is selected within the range of 10-40 μm. If a hardened resin coat does not contain 70% nor more of a hardened matter, aimed dimensional stability at an elevated temperature can not be obtained. If a coat thickness is not 3-20% of the thickness of the object film, an excellent dimensional stability can not be obtained. On the other hand, if the coat thickness is below 3%, dimensional stability is not enough. Though the thicker the coat is, the more the dimensional stability improves, a curling phenomenon becomes large when the coat exceeds 20%. The preferable coat thickness is 4-7% of the film thickness.

IPC: F24C15/04
Filed: 1982-06-16
Abstract: PURPOSE:To prevent the surface of a transparent body such as glass from being stained and the entire inner wall of the box-shaped heat cooking range is coated with a catalyst having an oil stain purifying capacity by a method wherein a part of the door of the cooking range is formed of the transparent body such as glass and a shield plate for covering the transparent body from inside the cooking range is attached to the door so as to open and close freely. CONSTITUTION:When a cooking material is put into the cooking range by opening the door 3 and then the door is closed, a lever 16 comes into engagement with an engaging section 15 of a movable frame 14. In this case, the lever 16 is lifted upward by a spring 19 so the shield plate 12 remains closed. In case where it is desired to look into the range during cooking, a switch 7 for opening and closing the shield plate and for concurrently lighting up an inner lamp may be lowered so that the lever is lowered against the force of the spring 19 to push the movable frame 14 downward, to thereby open the shield plate 12. In this case, a microswitch 18 is closed by an arm 17 so that the inner lamp is lighted up simultaneously. Further, when the switch 7 is released from one's hold, the movable frame 14 which is in engagement with the lever 16 due to the force of the spring 19 to close the shield plate 12 and the inner lamp is put off simultaneously. In addition, as the shield plate 12 is also coated with the same kind of catalyst as coated on the inner wall of the range, the transparent body 9 is not stained.

Title: Detection level adjusting device
Inventor: KURITA KENJI
IPC: G01V8/12
Filed: 1980-07-31
Abstract: PURPOSE:To automatically set a reference level and to automatically discriminate whether paper, a liquid, etc. exist or not, by storing a reference level for detection, in a memory, in a copying machine, etc. CONSTITUTION:An analog output of a photodetecting part consisting of a resistance R5 and a photoelectric conversion element OE2 is supplied to an AD converter ADC, and its converted output is stored in a memory ME through a control device CTL. When paper P is inserted and an optical path emitted from a lamp L to OE2 is shut off, a detection output becomes maximum. On the other hand, when the paper P is drawn out and a light beam from the lamp L is made incident to OE2, the detection output becomes minimum. CTL calculates an intermediate value as a reference value from a maximum value and a minimum value of MEM, and this reference value is stored in MEM. In case when paper is detected, whether it exists or not is decided by relation of magnitude between said stored reference value and the detection output.
