Title: Image reader
Inventor: KIMURA TAKASHI
IPC: H04N1/12
Filed: 1989-03-29
Abstract: PURPOSE:To attain highly accurate image reading work by constituting many optical fibers with an interval between adjacent optical fibers so that the part of the interval in response to both edge parts of a main scanning line is dense compared with the part of the interval in response to the central part of the main scanning line. CONSTITUTION:A reading original S is placed on an original platen 12 and while carrying the original platen 12 in the direction of an arrow A, an illuminating mechanism 14 is driven. Thereby, a laser beam L sent from a laser oscillating tube 18 is deflected in the direction of an arrow C by a galvanometer mirror 20 and the original S is irradiated with the laser beam L in the direction of an arrow B (in a main scanning direction) through a scanning lens 22 and a mirror 24 along the main scanning line 36 of the original S. Image information is picked up from the original S as an optical signal by the beam L and introduced to a photomultiplier 28 from the part on which the illuminating lights of optical fibers 30a and 30b which constitute optical guides 26a and 26b respectively are made incident. Then the information is photoelectrically read. Thus a reflecting light including the image information along the main scanning line 36 of the original S can be introduced to the plier 28 in a condition free from unevenness in light quantity and the highly accurate image reading work is realized.

Title: Roller bearing having synthetic resin cage
Inventor: TAKANO SUSUMU
IPC: F16C33/46
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To improve reliability and durability of synthetic resin cages incorporated into a roller bearing by arranging a locking part for preventing displacement on the shaft directional outside of the cages. SOLUTION: Cylindrical inner race raceway tracks 15, 15 are formed on an outer peripheral surface of an inner race 11, and rollers 14, 14 are arranged between the inner race raceway tracks and an outer race raceway track 16 to be held by synthetic resin cages 5a, 5a so as to be freely rollable. Engaging projections 8a, 8a projected on an inner peripheral side surface of column parts 4b, 4b are arranged in tip parts of the column parts 4b, 4b to prevent these synthetic resin cages 5a, 5a from being displaced in the shaft direction to be put in a state where rim parts 6, 6 for constituting the synthetic resin cages 5a, 5a exist on the shaft directional both sides of the rollers 14, 14.  Thus, even when the column parts 4b, 4b of the synthetic resin cages 5a, 5a are deformed outward in the diametrical direction as these proceed to the tip parts, displacement in the shaft direction of the rollers 14, 14 can be prevented by the rim parts 6, 6 to thereby prevent falling-off of the rollers 14, 14 in spite of deformation of the synthetic resin cages 5a, 5a.

Filed: 1985-04-12
Abstract: PURPOSE:To improve the handling performance of a cylinder mechanism by providing a weight member which is fitted in an elastic member fixed annularly in a nearly ring-shaped recessed part formed in a rotating body and inserted loosely into the recessed part.

IPC: H01M50/572
Filed: 1987-03-31
Abstract: PURPOSE:To improve safety of a battery by disposing electrolyte gelatinizer in the battery which reacts making contact with nonaqueous electrolyte to gelatinize the electrolyte and reduce the quantity of current for preventing an abnormal rise of the temperature of the battery when the temperature of the battery reses to a predetermined temperature. CONSTITUTION:For a battery including a negative electrode 2 with light metal as active material, a positive electrode 1, and nonaqueous electrolyte, electrolyte gelatinizer 5 is disposed in the battery which is normally insulated from the nonaqueous electrolyte and which makes contact with the nonaqueous electrolyte when the battery temperature rises to a predetermined temperature to react and gelatinize the electrolyte. A factor for an abnormal rise of the battery temperature is increase of short-circuit current, and when the battery temperature rises a little caused by an external short circuit of the like, the electrolyte gelatinizer 5 enclosed by a member 4 which dissolves at this temperature comes into contact with the electrolyte to gelatinize it and reduce short-circuit current. An abnormal rise of the battery temperature can thus be prevented. As the electrolyte gelatinizer 5 is insulated from the electrolyte normally, it does not give any harmful effects to normal battery reaction.
