Title: Scanning converting method
Inventor: DAGURASU POORU SUZAAKOUSUKI
IPC: G06F3/12
Filed: 1989-08-18
Abstract: PURPOSE: To improve the precision by judging a deviation term including the deviation value between a 1st integer coordinate point adjoining to one end point of a straight line and the one end point from respective deviation values which are sequentially and cumulatively calculated, and successively selecting plural integer coordinate points adjacent to the straight line up to the other end point. CONSTITUTION: A source data source 18 specifies the real end points of a straight line as to each segment. A scan converter 20 which executes a program in a read-only memory(ROM) receives data from the data source 18 and stores the data in a random access memory(RAM) 24. Once actual pixel coordinate points are determined, they are supplied as a data series regarding the whole image to be printed to a printer controller 26. Then the printer controller 26 relates the data with printing elements while individual ink jet printing elements, etc., of a printer 28 scan a printing medium. Thus, the scan converter 20 converts text information, etc., into a specific coordinate grating in addition to the scan conversion. Consequently, the precision is improved.

Title: Drum type clothes drier
Inventor: KITAMURA SUSUMU
IPC: D06F58/02
Filed: 1992-08-10
Abstract: PURPOSE:To provide a drum type clothes drier having a short drying time and capable of reducing the entangling of clothes and drying irregularities. CONSTITUTION:A double-blade fan 8 is rotated in the reverse direction during the period from the operation start to the constant-rate drying stage when the temperature in a drum 1 is kept nearly constant. A fixed air quantity can be secured at the hot-air circulation side section 20 of a fan casing 19, thus the temperature in the drum 1 can be quickly increased. The entangling of clothes is liable to occur at the initial stage of operation, and reversing actions at the short cycle of the positive rotation for 10sec, stop for 2sec, and reverse rotation for 10sec are repeated for the rotation of the drum 1 during this period. When above two controls are combined, the time until the quantity of inserted clothes is judged is shortened, and the whole drying time can be shortened.

Title: Method for molding resin employing
Inventor: TAKATORI HIROYUKI
IPC: B29C33/76
Filed: 1988-08-30
Abstract: PURPOSE:To make the liquating property of molten alloy favorable and consequently obtain a molded item, which is excellent in dimensions and no after- machining of which is necessary, by a method wherein molding is done after lubricating skin is formed onto the surface of a core. CONSTITUTION:A core is produced by casting alloy having the range of melting points of 90 - 200 deg.C, especially Sn-Bi-Pb based alloy with a conventional casting machine. The formation of lubricating skin onto the surface of the core is done by evenly applying lubricant onto the surface of the core or by applying lubricant on a casting mold at the casting of the core. As the lubricant, casting releasant, organic lubricant, fats and oils such as paraffin, wax and the like, polyfluoro-compound powder and the like are effective and especially fuorocarbon, ethylene-bis-stearylamide and zince stearate are used favorably. By employing releasant in combination with the lubricant at the casting of the core, more effect is produced. Since said lubricant is incompatible with the alloy and exerts no bad influence on the alloy, no hindrance is constituted to the reuse of the alloy.

Title: Light-emitting element using amorphous semiconductor superlattice structure
Inventor: HIROSE ZENKO
IPC: H01L33/42
Filed: 1984-10-15
Abstract: PURPOSE:To enable a large area and high efficiency by a method wherein hetero-junction superlattice structure is held by a p<+> layer and an n<+> layer, forward DC voltage or high-frequency voltage is applied,carriers are injected to a potential well generated in superlattice structure from the outside and stored,and light is emitted. CONSTITUTION:With a light-emitting element 1 constituted by holding hetero-junction superlattice structure 6 by a p<+> layer 2 and an n<+> layer, carriers are injected to a potential well generated in superlattice structure 6, luminous beams are extracted effectively, and p<+>-i-n type element structure is formed. The light-emitting element 1 is operated by applying high-frequency voltage extending over a wide range. Especially when pulse voltage is applied, not only a large quantity of carriers can be injected into superlattice structure 6 but also carriers are confined in a well layer even after removing pulse voltage. Consequently, carriers remaining in superlattice structure are not separated in the opposite directions by internal voltage, and can contribute to light emission, thus manufacturing a light-emitting element having higher luminance. Since luminous energy is fairly smaller than the energy gap of the n<+> layer or the p<+> layer in the light-emitting element,reabsorption in an electrode is avoided, thus improving luminous efficiency.

Abstract: PURPOSE:To facilitate the removal of a magnetic material as foreign matter attracted to a magnet, by bypassing a line of magnetic force in an air gap of a permanent magnet along a magnetic adjuster to be converted to a magnetic body with the setting of temperature. CONSTITUTION:An object to be inspected is arranged in an air gap 1A of a pair of permanent magnets 1 separated as opposed to each other and when a magnetostatic field is applied to the object being inspected, an iron yoke 2 makes up a magnetic circuit to reduce a leakage flux. When magnetic material brought by mistake is attracted to the air gap 1A, first, the magnetic adjuster 7 is heated up to a high temperature by a temperature varying means 8 to be turned to a nonmagnetic body. Then, a heater is turned OFF or a cooler is turned ON simultaneously by the temperature varying means 8 to shift the magnetic adjuster 7 to a low temperature and converted to a magnetic body. This forms a bypass B instead of a normal path A with a shunt circuit 6 thereby enabling the removal of the magnetic material.
