Title: Screw for synthetic resin extruder or injection molder
Inventor: FUKUMIZU SHINICHI
IPC: B29C48/395
Filed: 1979-12-11
Abstract: PURPOSE:To improve a shearing effect and an agitating effect and increase a mixing effect as well as a number of revolutions of the screw by a method wherein a mixing section having a different sectional configuration equipped with a feeding blade section and a returning blade section succeeding to the feeding blade is provided at the proper position of the screw. CONSTITUTION:The mixing section 7 of the different sectional configuration eqipped with a plurality of mixing blades 8 consisting of the feeding blade section 8a having a lead angle for sending the resin to the tip end side of the screw and the returning blade section 8b located at a fore side of said blade section 8a and having a lead angle for returning the resin to a hopper 3 side is provided at the proper position of the screw 1. A small shearing force exerts at open sections 10 and a time necessary for passing the resin through mixing flight sections 9 is very short, therefore, only little heat is generated in the resin and the number of revolutions of the screw 1 may be increased because of the little heat generation. The resin will never go to the tip end of the screw due to the presence of the returning blade section 9b while the resin is mixed sufficiently by eddy currents at the open sections 10.

Title: Endoscope
Inventor: KIMURA HIROYUKI
IPC: A61B1/07
Filed: 1983-09-02
Abstract: PURPOSE:To illuminate more efficiently the inside wall surface of a tube by forming an endoscope in such a way that the illuminating light transmitting a lens is distributed darkly at the center and brightly annularly at the periphery to the central part at the exit end of an optical element for accepting the illuminating light from a light guide. CONSTITUTION:The illuminating light made incident from a light guide 3 to the inside of an optical element 5 repeats reflection on the circular conical surface 12 of a recess 10 and the outside circumferential surface 13 of the element 5 and thereafter the light is emitted annularly from an exit end 9 and is condensed by passing through a convex lens 7. The inside wall surface 14 of the tube and a visual field range X are thus concentrically illuminated in the case of illuminating said wall surface. The emphatic illumination is thus efficiently accomplished without wasteful irradiation of the illuminating light in the forward direction of the tube axis.

Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To stably obtain a color image excellent in quality by preventing the adherence of magnetic carriers on a photoreceptor drum surface from two component developing device on the upstream side, among plural units of developing devices arranged along the photoreceptor drum periphery, reducing the carriers contamination into the magnetic one component developing device on the supreme downstream side, and making the prime development possible to be performed even with respect to the one component developing device. SOLUTION: A developing sleeve 41 of two component device is rotated at a part facing a photosensitive drum 1 in the direction of traveling opposite thereto, and allowed to develop the electrostatic latent image on the surface by holding the two component developer 45 on the sleeve 41 in contact with the surface of the drum 1 while shifting in the opposite direction. The carriers 45C2 after developing with use of toner 45T, since the carriers 45C2 has the charge of reverse polarity against the toner, is vulnerable to part in the drum 1 direction on the downstream side of the sleeve rotating direction at the developing part, but liable to be fetched by the subsequently coming carriers 45C2, since the traveling direction of the developer by the sleeve 41 is in the opposite direction, therefore the carriers 45C2 are prevented from sticking on the surface the drum 1.

Title: Speckle length measuring instrument
Inventor: AKISHIBA YUUJI
IPC: G01B11/00
Filed: 1990-06-19
Abstract: PURPOSE:To measure length with high accuracy by switching reference data one after another before a decrease in approximation extent and calculating the movement distance of a body as the integral value of a fine movement quantity in a range wherein a high approximation extent is obtained. CONSTITUTION:A microcomputer 7 judges whether or not an external timing signal Pe rises or not. When the judgement result indicates NO, the total value of difference data is calculated and compared with a switching reference value; when the total value is larger than the reference value, a return to a starting data fetch process is made. When the total value is less than the reference value, on the other hand, a data selector 53 is switched to switch the reference data to current data. Then the integral value of the body movement quantity is changed into the current movement distance after the start of the length measurement of the body and then a return to the starting data fetch process is made. When the rising of the signal Pe is detected, on the other hand, the difference between the calculation result of the movement distance at the rising point of time and the calculation result of the movement distance at a last rising point of the signal Pe is calculated and displayed 9,.
