Title: High frequency hardening method
Inventor: KAJITANI KIYOKAZU
IPC: H05B6/10
Filed: 1997-11-11
Abstract: PROBLEM TO BE SOLVED: To prevent soft spot in quenching by increasing the power to be supplied to an induction heating coil when one end part and the other end part of a work are heated compared with the case when other parts are heated to uniformly harden from one end part of the work to the other end part. SOLUTION: In a condition where a tip part 22 of a square member 20 is away from an induction heating coil 16, the high frequency power of approximately 75 kW and of approximately 5.8 kHz in frequency, is supplied to the induction heating coil 16. The high frequency power is increased by supplying the high frequency power of approximately 400 V in voltage, approximately 85 kW and of approximately 6.2 kHz in frequency to the induction heating coil 16 after a tip 22a of the square member 20 reaches the prescribed distance B before the induction heating coil 16. The time when the high frequency power to be supplied to the induction heating coil 16 is increased, is the time until the tip part 22 of the square member 20 passes the induction heating coil 16.  Also when a rear end part 24 of the square 20 passes the induction heating coil 16, the high frequency power is also increased similar to the case that the tip part 22 passes the coil.

Title: Image processing unit
Inventor: SAKANO YUKIO
IPC: H04N1/387
Filed: 1995-11-01
Abstract: PROBLEM TO BE SOLVED: To obtain the image processing unit with diversified half-tone screen functions. SOLUTION: An unstable LSB from an A/D converter of an image read section is used for a random pattern generating signal. A dot pattern generator 241 generates a pattern signal K based on various control signals J and a signal S1 to select and designate kinds of patterns by the entry operation. A select signal S2 of a selector 242 is a signal to select either the signal K or a signal D0 being the LSB of an image signal. A half-tone screen signal M is generated by ORing the pattern signal L and a binary image signal H and a half-tone dot meshed screen signal N is generated by ANDing the pattern signal L and the binary image signal H at an AND gate 24. Since a random dot pattern is obtained by using the random property of the LSB of image data, no special random pattern generator is required. Thus, the random pattern is obtained inexpensively with a simple configuration.

Abstract: PURPOSE: To manufacture an interlayer insulation film excellent in flatness at a small number of steps by a method wherein a portion other than the portion where the interconnection of specific patterns out of metal films formed in a semiconductor substrate is insulated. CONSTITUTION: Photoresist is applied to the surface of an Al film 28, which is exposed to light and developed to form a resist mask 30 of the same pattern as a specific pattern of the interconnection. Next, oxygen is ion-implanted to form an oxygen ion-implanted layer 34 and a specific pattern interconnection 36. Next, the resist mask 30 is removed from an Si substrate 10 that oxygen is ion-implanted, and this Si substrate 10 is annealed in a furnace at 600 deg.C. Thus, the ion-implanted layer 34 that oxygen ions are implanted becomes an Al2 O3 layer (insulation material layer) 34a and is crystallized to form interconnection 36 of a specific pattern. Thus, after the interconnection 36 is formed, an interlayer insulation film is formed. As the Al film 28 is not etched in this method, a recess is not formed by etching in the Al film 28.
