Title: Alignment optical system
Inventor: UEHARA MAKOTO
IPC: G03F9/00
Filed: 1986-03-04
Abstract: PURPOSE:To expand an effective exposure area and to increase the degree of freedom for the design and production of semiconductors by reflecting observation light obtained from an alignment mark on a reticule plural times by a plural-times reflecting member so as to lead the plural reflected light rays into an objective lens. CONSTITUTION:A reflecting member is constituted of the plural-times reflecting member (three-times reflecting member 70) for reflecting observation light 20a obtained from the alignment mask 60 plural times and leading the plural reflected light rays into the objective lens 3. Even when the member 70 is arranged so that the 1st reflecting part for reflecting the observation light 20a at first is close to the pattern surface of the reticule 6 and the objective lens 3 is arranged on a position separated from the pattern surface of the reticule 6, the observation light 20a reflected by the 1st reflecting part is again reflected one or more by other reflecting parts of the member 70 and led into the objective lens 3. Consequently, the effective exposure area of the exposure optical system can be expanded within an aberration correcting area and the degree of freedom for the design and production of semiconductors can be increased.

Title: Optical interference type gas calorific value measuring apparatus
Inventor: OKAZAKI IWAO
IPC: G01N25/20
Filed: 1987-03-02
Abstract: PURPOSE:To reduce the consumption of standard gas by keeping the concn. of the standard gas in a standard cell constant over a long time, by a method wherein the gas discharge port of a standard gas cell is allowed to communicate with the fuel gas discharge pipeline of a measuring gas cell to discharge fuel gas. CONSTITUTION:When gas having a known calorific value as near as possible to the calorific value of the fuel gas flowing through a gas supply line L is selected to operate an apparatus, the fuel gas flowing through the gas supply line L flows in the first cell 1 while the flow rate is adjusted to a definite value by a flow control mechanism 2. The standard gas received in a cylinder 8 flows in the second cell 4 while the flow rate thereof is controlled to a definite value by a flow rate control mechanism 5 and issues to a discharge port 20 after a definite time while discharges the gas remaining in the cell 4. When the supply of the standard gas from the cylinder 8 is stopped in this state, the standard gas received in the second cell 4 communicates with the discharge port 20 through the fuel gas and, therefore, the initial concn. can be kept in the cell 4 over a long time.

Filed: 1980-04-09
Abstract: PURPOSE:To increase the coercive force of a magnetooptical storage disk at room temperature by forming an amorphous thin film, having magnetic anisotropy at right angles to the substrate, on a base disk made of glass or resin. CONSTITUTION:On disk 7 made of glass or resin, thin amorphous film 6 made of GdTbFe is formed in proportion of 0.24:0.18:1 of Gd:Tb:Fe and on this thin amorphous film 6, an SiO2 film is formed as protective film 5 in a film thickness of 5,400Angstrom . Thin amorphous film 6 has magnetic anisotropy at right angles to the surface of disk 7. If HeNe laser light is used as a reading light source, this protective film 5 increases the Kerr turning angle by about 0.5 deg.. The film thickness of amorphous film 6 should be relatively large, i.e. about 1,000Angstrom  when a reproducing means utilizes the Kerr effect or relatively small, i.e. 500-800Angstrom  when it utilizes the Faraday effect. In the recording and reproducing operation of the thus obtained recording disk, laser light 1 has the optical path controlled via reflective mirror 2 and, after being focused through lens system 3 provided with auxiliary magnetic- field generating coil 4, irradiates the magnetooptical recording disk, recording information.

Abstract: PURPOSE: To form a silicide film safely with low resistance by a method wherein a silicon oxide film not exceeding a specific film thickness is formed on a silicon substrate using a oxidizing solution to perform a specific heat treating step on a metallic film formed on the silicon oxide film. CONSTITUTION: A field oxide film 12 made of silicon dioxide is formed on a p-type silicon substrate 11 further to form a diffused layer 13 by impurity ion implanted heat treatment and after removing a natural oxide film on the surface using diluted fluoric acid to be immersed in hydrogen peroxide solution for three minutes.
