Abstract: PURPOSE:To deposit an insulating film while realizing sufficient adhesion and coverage by ion assist deposition. CONSTITUTION:A wiring board 6 for depositing an insulating film of metal oxide is held by a substrate holder 5. High vacuum is established in a vacuum chamber 1 and a mixture of an inert gas e.g. argon, and an active gas, e.g. oxygen, is subjected to ionization and projected from an ion gun 9 through a shutter toward the wiring board 6 placed in the vacuum chamber 1.

Title: Method for compensating burst level for adjusting color density
Inventor: HASHIMOTO HIROSHI
IPC: H04N9/77
Filed: 1991-12-20
Abstract: PURPOSE:To prevent the variation of a burst level value from appearing as a color noise by finding out a difference between the mean value of burst level values and a reference value by comparing them. CONSTITUTION:A microcomputer 40 compares the 2nd detection value with the reference value read out from a register 42, and when the difference between them is less than a set value, allows the register 42 to output the reference value to an ACC circuit 16 as a burst level value. When the difference is equal to the set value, a corrected value obtained by adding +1 or -1 to the detection value is written in the register 42 as a new reference value and outputted to the circuit 16 as a new burst level value. When the difference exceeds the set value, the detected value is set up as a new reference value, and is written in the register 42 and out-putted to the circuit 16 as a new burst level value. Even when the mean value of the burst level values of digial video signals successively sent is varied within a fixed range, the variation does not appear as a color noise on a plane.

Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To print at the ends of printing paper without causing the enlargement of a device by carrying out printing at the return section or the forward section as marks are printed at the left end or right end, and also printing marks at the reverse section from the return section to the forward section or at the reverse section from the forward section to the return section. SOLUTION: In the forward section and return section, an ordinary printing is implemented. Also, in a section between the position of a middle in a reverse section from the forward section to the return section to a middle in a reverse section from the return section to the forward section, printing is conducted including mark printing. Namely, marks 63 are required to be printed at the receipt 61; in this instance, marks 63 exist at the left end of the receipt 61. As a result, the carriage prints marks at the timing of its reciprocation and, besides, prints marks utilizing a reverse section from the return section to the forward section. This requires no expansion of the printing section, and prevents the printer from being enlarged in size.

IPC: B29C43/24
Filed: 1992-12-25
Abstract: PURPOSE:To eliminate a levitation of a rubber and an air entrapment to easily pull out the rubber by a method wherein a kneaded rubber is calendered to a predetermined rubber thickness, attached to a cloth liner, pulled out, and vulcanized. CONSTITUTION:In a calender roll machine, a kneaded rubber 60 is successively passed through between a side roll 10 and a top roll 20, between the top roll 20 and a center roll 30, and between the center roll 30 and a bottom roll 40. Thus, the rubber is sequentially calendered in three stages to a rubber sheet 60 of a uniform thickness. This calendered rubber sheet 60 is attached to a fed cloth liner 70 between the bottom roll 40 and a rubber roll 50, pulled out, and vulcanized. With the use of the cloth liner 70 in this manner, a high adhesion is obtained between the liner 70 and the rubber 60, thus preventing an occurrence of a levitation and an air entrapment and ensuring a smooth pull-out. The cloth linder 70 substituted for release paper can be repeatedly used economically.
