Title: Inking device of thermal transfer printer
Inventor: SHIODA TOYOJI
IPC: B41J31/16
Filed: 1990-03-02
Abstract: PURPOSE:To contrive to lengthen the life of an ink support by putting a hot-melt ink beforehand into the cylinder of an inking device, by heating the cylinder and winding the ink support round the outer peripheral face of an inking roller, which ink permeates and is discharged from, and by transferring and applying the ink to the ink support. CONSTITUTION:A cylinder 301 is heated by a heater 302 connected via a cylinder support 300 and an inking roller 304 is heated via the support 300 in the same manner as the cylinder 301. Between the internal surface of the inking roller 304 and the outer peripheral face of the cylinder 301, a predetermined very small gap 305 of not more than several mm is formed for the purpose of using a capillary phenomenon, and ink 303 is supplied to the very small gap 305 via a lower opening 306 by surface tension. The outer peripheral face of a subinking roller 308 partially comes in contact with the ink transfer part of the ink support 101. When the ink support 101 is caused to travel in the direction of rotation of the inking roller 304, ink is transferred to the ink support 101 by the surface tension of ink permeating the outer peripheral face of the inking roller 304.

Title: Preparation of super fine iron powder
Inventor: SUGA FUKUHIKO
IPC: B22F9/22
Filed: 1980-04-21
Abstract: PURPOSE: To prepare super fine iron powder, by hydrolyzing at a high temperature fresh FeCl 3  vapor in oxygen-hydrogen flames and reducing the resulting super fine iron oxide powder with hydrogen.  
     CONSTITUTION: When iron is put into a ferric chloride vapor generating chamber 3 and Cl 2  gas is introduced into the chamber, FeCl 3  vapor is readily and quantitatively evolved. The gas is mixed with an oxygen containing gas and sent into a gas mixing chamber 1, in which the gases are further mixed with hydrogen coming from  another route, and led to a burner 2 to react. Here, H 2 O formed by the combustion  of hydrogen reacts with FeCl 3  vapor in hot oxygen-hydrogen flames to produce  Fe 3 O 4  and HCl. Said Fe 3 O 4  forms solid nuclei in combustion exhaust gas, which  grow fine powder having a size under about 80mμ when the exhaust gas is gradually cooled as it passes through a flue. Super fine iron powder having a size under  about 80mμ is prepared by separating said fine powder and heating it at 450°C or  lower in hydrogen atmosphere to reduce.

Title: Portable type electronic computer
Inventor: YASUDA YOSHINORI
IPC: G06F1/00
Filed: 1985-03-15
Abstract: PURPOSE:To eliminate the necessity of the editing and transferring of the displaying data at the time of starting and to return to the condition instantaneously before the electric power source is turned off by backing up a RAM for displaying by the memory back-up circuit as well as a RAM for the main memory. CONSTITUTION:Since a RAM 4 for displaying is backed up from a memory back-up circuit 6 as well as a RAM 3 for the main memory, an electric power source is turned off, and even then, the data are preserved in the RAM 4, the after the electric power source is returned, a CPU 1 processes and controls the program from a ROM 2 where the stored program is stored beforehand, and the starting processing is executed. Consequently, the necessity to edit the data read from the RAM 3 to the data for displaying is eliminated, the processing time at the time of starting is shortened, returning can be instantaneously executed to the condition before the electric power source is turned off, and also, the complicated processing is not needed and therefore, the capacity of the ROM 2 can be made smaller.

Title: Dust collection method and its device in thermal cutting machine
Inventor: TSUTSUI KIKUO
IPC: B23K9/32
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To efficiently collect dust into the device over the entire area inside a dust collecting cabin. SOLUTION: Dust is sucked through a collecting duct 19 into the device 21 from a collecting part 17 provided above one of the side walls of a collecting cabin 15 covering above a machining table 5. With an air blower 23 provided above the side wall opposite from that of the dust collecting port, the outside air is blown in the cabin. The outside air so flown in becomes an upper air stream UAc in the upper part of the cabin and is exhausted from the dust collecting port 17. Current plates 25, inclined in the direction ascending the diffusion flow of the upper air stream against its flowing direction, are provided nearly parallelly at spaces apart from one another in the middle part in the height of the cabin, thereby stabilizing the upper air stream. Since the upper air stream sucks air in the lower part of the cabin, a stable strong ascending air stream AAt is generated there.  The dust in the lower part of the cabin 15 efficiently rises with the ascending air stream, joins the upper air stream and is sucked into the dust collecting device.

Abstract: PURPOSE:To operate coupling sleeves without troubles even when tilts are generated in a shift-fork, by forming the connecting surfaces of the pawl portions of the shift-fork in convex curved surface shapes. CONSTITUTION:A main body 21 of a shift-fork 20 is made of sheet metal, and a portion 22 at the side inner than an external form line except both end portions is half punched by means of a precise punching method and projected. The connecting surfaces 30 of pawl portion materials 28 are formed in convex curved surface shapes that the connecting surfaces draw arcs in the longitudinal directions of the outer circumferential grooves 9a of connecting coupling sleeves 9. Consequently, the connecting surfaces 30 and the inner flanks of the outer circumferential grooves 9a of the coupling sleeves 9 are maintained under line contact conditions because the connecting surfaces 30 are convex, curved surface shapes in the pawl portions 28 even when a shift-rod 16 is moved in the axial direction, the shift-fork 20 is deformed and tilts are formed. Thus, the coupling sleeves 9 are subject to thrust without being affected by the tils of the shift-fortk 20, and can smoothly be operated.
