Title: Character detecting and segmenting system for character reader
Inventor: SATO TOYOSHI
IPC: G06K9/34
Filed: 1985-08-30
Abstract: PURPOSE:To securely detect and segment one character even if a character with dot omission or a blurred character is targeted by comparing scan width, a gap slice value and a white data counted value according to the character pitch of a character string. CONSTITUTION:In correspondence to the predetermined scan width according to the character pitch of the character string of one line, which is read out of a detection and segment address detecting memory, a white data counting means scans a projection memory at a predetermined reference address, and outputs a white data counted value which is obtained by detecting and counting an initial white data from a horizontal projection data. A detection and segment address deciding means compares the white data counted value obtained from the white data counting means with the gap slice value read out of the detection and segment address detecting memory. Based on the compared result, a detection and segment address at which character pattern data of one character is segmented in a line buffer memory is decided.

Title: Oil feeding method
Inventor: HASEGAWA KAZUO
IPC: B63B27/24
Filed: 1983-10-14
Abstract: PURPOSE:To make high pressure oil feeding attainable as well as to aim at shortening the time required for oil feeding, by coupling an interval between a ship and a land tank with an oilproof delivery hose resistible to the high pressure oil feeding operation. CONSTITUTION:An interval between an oil tanker 1 and a land tank 2 is coupled with an oilproof delivery hose 3 being moored alongside by a wire rope 4. The hose 3 is rolled round on an auto-tension reel device 5 mounted on a ship, while a wire rope 4 mooring the hose 3 alongside is hoisted on a wire winch 6. In time of oil supply, the oilproof delivery hose 3 is moored alongside by the wire ropes 4, while its tip end is extended as far as the land tank 2. Since oil feeding takes place in relatively high pressure, the time required for oil feeding can be shortened.

Title: Manufacture of semiconductor device
Inventor: MOMOTOMI MASAKI
IPC: H01L21/28
Filed: 1981-11-30
Abstract: PURPOSE:To form electrode wiring having low resistance by adding Ti, etc. to a target consisting of the silicide of Mo or W and executing pre-sputtering before the film of the silicide is shaped through a sputtering method. CONSTITUTION:Ti is doped to the MoSi2 target by 1-10%, and sputtered. Since Ti is easy to be combined with oxygen more than Si, Ti is combined with oxygen as a residual gas in a chamber when MoSi2 to which Ti is added is pre-sputtered as the target, and there is hardly oxygen in the chamber when sputtering. Accordingly, the electrode wiring consisting of an MoSi2 film, which has no oxygen and resistance thereof is low, can be shaped onto a substrate. Zr, Ta or Hf can be utilized besides Ti as an additive.

Abstract: PURPOSE:To enable automatic selection of a character form in a character string aligned in a direction at right angle with a direction of character string of a document as a whole by detecting a character having two types of character form in a character string aligned in a direction at right angles with a document printing direction and selecting/printing a character form which is different from the character form of characters arranged in a printing direction. CONSTITUTION:A character string/arrangement judgement part 10 identifies characters having two types of character form for lateral/vertical writings, and compares adjoining characters before and after the characters having two types of character form with prearranged characters, when the characters with two types of character forms are selected. A character form selection part 11 judges that the character string is at right angles with a printing direction, if the characters before and after coincide as a result of the comparison. Then said part 11 selects the character form which is different from that of the character string aligned in the printing direction. When the characters before and after do not coincide, the character form selection part selects the same character form as that of the character string arranged in the printing direction. The character selection part 11 passes a selected character form to a printing control part 12. The printing control part 12 controls a printer 5 as usual so that designated characters may be printed.
