Title: Optical scanning device
Inventor: ITABASHI AKIHISA
IPC: G02B26/10
Filed: 1989-07-24
Abstract: PURPOSE:To make an optical scan of good quality by correcting an electric signal with the control means of an actuator for a cylindrical lens according to the detected temperature of a sensor and compensating the temperature characteristics of the actuator. CONSTITUTION:The temperature TA of the actuator 7 is detected by the sensor 8A, the temperature TL of a laser as a light source 1 is detected, and a voltage V(z) is stored in a ROM 13 according to those detected temperature values. A synchronizm detector 10 reads out information with a synchronous clock which is generated every time deflected luminous flux is detected and drives the actuator through a D/A converter 14 and a driving circuit 15 to move a cylindrical lens 2 on the optical axis, thereby removing the curvature of field in a subscanning direction. Compensated voltage signals VL(z) and VAL(z) when wavelength variation takes place by variation in the laser temperature TL and when the changes in the operation characteristics of the actuator 7 and the wavelength of the laser 1 occur are also read out of the ROM 13 as neces sary. This constitution uniforms the light spot diameter in the subscanning direction with extremely high accuracy, so the optical scan of good quality is attained.

Title: Medium detecting mechanism
Inventor: SAITO MASAHIRO
IPC: G01V9/00
Filed: 1989-07-26
Abstract: PURPOSE:To accurately monitor the traveling condition of a medium by providing transfer rollers with a sensor function for detecting the presence of a medium, so that the presence of the medium can be directly detected by the transfer rollers. CONSTITUTION:A medium 1 is successively fed and transferred by transfer rollers 3 in the inside of a transfer passage 2.

Title: Method of cleaning pipe
Inventor: SAGAWA SHIZUO
IPC: B08B9/04
Filed: 1987-08-01
Abstract: PURPOSE: To uniformly peel and remove the scale on the inside wall surface of a pipe to be cleaned having different diameter parts by putting groups of special small balls into the pipe and impressing a water pressure on one of the groups of these small balls, thereby passing the groups of the small balls approximately along fluid dynamic velocity distribution curves. CONSTITUTION: The many small balls 2 driven with many pins so as to expose heads receive the water pressure and flow approximately along the fluid dynamic velocity distribution curves 4 in the form of lumps in the pipe 3. The small balls 2 which come into contact with the inside wall of the pipe 3 peel the scale of the inside wall of the pipe 3. When the small balls 2 come to the part of the large diameter or small diameter of the pipe 3, the lumps of the small balls change to the velocity distribution curve meeting the pipe diameter and still maintain contact with the inside wall surface of the pipe 3, thereby uniformly peeling the scale sticking to the entire area of the inside wall surface of the pipe 3 is made possible.

Title: Separation of component
Inventor: NAKAJIMA MITSUTOSHI
IPC: C07K1/14
Filed: 1994-08-15
Abstract: PURPOSE:To efficiently separate, e.g. an enzymatically synthesized dipeptide component by bringing an organic phase into contact through a charged membrane with an aqueous phase containing a target component group and a non-target component group having a partition coefficient higher than that of the target components group and extracting the target component group into the organic phase. CONSTITUTION:This is a method for separating components by bringing an organic phase into contact with an aqueous phase and extracting the target component group contained in the aqueous phase into the organic phase. In this method, an organic phase 4 composed of an organic solvent for extraction is brought into contact through a charged membrane 2 in the apparatus body 1 with an aqueous phase 3 composed of a reaction solution obtained by a reaction between a substrate (A) belonging to the first non-target component group and another substrate (B) belonging to the second non-target component group respectively having an aqueous phase/organic phase partition coefficient larger than that of the target component group in the presence of an enzyme catalyst (C) for production of the target component group composed of a product (P) and containing these components. Thereby, the target component group (P) contained in the aqueous phase 3 is extracted into the organic phase 4, thus separating a dipeptide component such as benzyloxycarbonylasparticphenylalanine methyl ester from benzyloxycarbonylaspartic acid and phenylalanine methyl ester.

Title: Automatic document feeder
Inventor: SEGAWA HIROYUKI
IPC: B65H29/68
Filed: 1991-07-31
Abstract: PURPOSE:To shorten a time required for exchanging a document without increasing a feeding speed by feeding the next document to an image reading position after feeding the document whose image has been already read to an intermediate position, and feeding the document being at the intermediate position to an ejection part when the read of the image of the document is finished. CONSTITUTION:When the read of the 1st document D1 is finished, an automatic document feeding processor starts the feeding action of the 2nd document D2 from a previous put position according to a signal from a main processor. In the case that the 1st document D is of a size shorter than specified length, step feeding action is executed. Namely, the document is not directly ejected from an exposing position to a paper ejection tray 18 but fed to stand by at the intermediate position where the leading edge thereof reaches a paper ejecting sensor 15 between the exposing position and the tray 18. Thus, the document D2 fed to the exposing position next is started to be fed when the document D1 at the exposing position comes to the intermediate position before it advances to a position where it can be ejected to the tray 18, thereby shortening the document exchanging time.
