Title: Formation of fine pattern
Inventor: AKIYAMA TATSUO
IPC: H01L21/3065
Filed: 1985-10-24
Abstract: PURPOSE:To enable the formation of fine patterns by diminishing a size transfer difference in RIE etching by effecting the RIE etching after coverint the pattern obtained by exposure and development of a photoresist layer laminated on a coating layer formed on a semiconductor substrate with an extremely thin noble metal film. CONSTITUTION:When a fine pattern is formed on a coating layer 2 which is formed on the surface of a semiconductor substrate 1, a noble metal element of 10-50Angstrom  is formed on a pattern 3 obtained by patterning a photoresist layer coating said coating layer. This covering layer 4 is subjected to RIE etching. As the noble metal layer, a single substance of Au, Pt, or Pd, an alloy of those elements, or a mixed sputtering layer of single substance elements are applicable and such noble metal elements are selected because their sputtering rate is faster than that of other elements. As a coating quantity, the amount under 10Angstrom  is ineffective and that over 50Angstrom  causes the prolongation of the etching time by sputtering which impedes mass production.

Title: Liquid fuel combustion apparatus
Inventor: HIRATA YASUSHI
IPC: F23D11/40
Filed: 1983-12-15
Abstract: PURPOSE:To suppress accumulation of tar, and to enhance combustion property, by radially providing projected parts around the opening on the surface of a mixing disk provided at the top of a vaporizing chamber, facing to the vaporizing chamber, in a combustion apparatus of vaporized and pre-mixed combustion type, using kerosene for fuel, applied to a heating apparatus for household use. CONSTITUTION:Projected parts 9 are radially provided on a mixing disk 3. The projected parts 9 are formed in an arc. Fuel injected from a fuel nozzle 6 into a vaporizing chamber 1 is gasified and heated by a vaporizing wall surface 7, flowing into a combustion part 8, passing through the opening 3a of a mixing disk 3 provided on the top of a vaporizing chamber. During the time, fuel is vaporized on the vaporizing surface 7, sufficiently mixed with combusution air by the aid of the projected parts 9, and is fed into the combustion part 8 from the opening 3a. With such an arrangement, sparks does not occur, because unvaporized particles contained in fuel do not scatter and do not flow into the combustion chamber 8. At the same time the mixing property of vaporized gas with the air is very much heightened. Flames are stabilized, combustion property is improved, and carbon monoxide is not produced, and then tar is prevented from forming on the wall surface of a vaporizing chamber.

Title: Method for measuring position of work
Inventor: NISHIDA YOSHIHARU
IPC: G05B19/18
Filed: 1992-09-04
Abstract: PURPOSE:To correct the positional deviation of a work in a short time with relatively high precision by determining a coefficient with a specific method when a coordinate conversion coefficient is found. CONSTITUTION:A conversion matrix T (equivalent to coordinate conversion coefficient) is found based on measured positions Pmi of points PTi (i=1, 2,...n) on the actual work corresponding to representative points Psi set on a model work and the calculated points Pdi of points Pti on the actual work which are obtained from the representative points Psi on the model work by coordinate conversion. The coordinates of other points (except the representative points) on the model work are converted to measure the positions Pd of points Pt on the actual work corresponding to other points Ps on the model work. When, however, the conversion matrix T is found without fixing the representative points, the conversion matrix T is determined by setting the partial differential value of each parameter of the conversion matrix T of an evaluation function J as the sum of the squares of distances between the measured positions Pmi and calculated positions Pdi of the points Pti on the actual work to 0.

Title: Switch gear for high tension load
Inventor: NAKADA RYOSAKU
IPC: H01H9/54
Filed: 1990-09-05
Abstract: PURPOSE:To reduce the loss produced in SCR and completely cut out the load side from a power source at the time of blackout by connecting SCR's arranged in opposite parallel and opposite to each other and a first mechanical breaker in series between a power source side terminal and the load side terminal, and connecting a second mechanical breaker in parallel with these parallel SCR's. CONSTITUTION:When a second breaker S2 is opened, an arc 40f is produced between a tip 33 and a fixed electrode 7f. The arc voltage is applied to an SCR. The arc voltage reaches a lowest actuation voltage, the SCR becomes ON and the current moves to the SCR. The current between the connection terminal 4f and the movable electrode 8f flows through the route via an attachment piece 23, an SCR 9f or 10f, an attachment piece 29, and an auxiliary contact piece 28. As a result no voltage exists between the electrode 7f and a tip 33 of the electrode 8f and the arc disappears. When the phase of the power source becomes 0 deg. or 180 deg., the SCR 9f becomes non-conductive and the energization between the terminals 4f and 5f is shut off. When the electrode 8f further moves and the first breaker S1 is opened, the arc is not produced because the SCR is non-conductive.
