Title: Electrophotographic copying device
Inventor: MURATA MITSUHIRO
IPC: H01H35/42
Filed: 1982-03-04
Abstract: PURPOSE:To obtain sharp picture images irrespectively of humidity condition by detecting the high humidity condition or condensation condition at the inside and outside of a device body and controlling the high voltage current to be applied to an electrifier. CONSTITUTION:When the high humidity condition or condensation condition around an electrostatic drum 8 is detected with a switching element 22, the signal from a detecting part 23 is conducted to a control system 25. When the moisture responsive film 29 of the element 22 absorbs moisture in the high moisture condition, the resistance of the element 22 changes. Thereupon, an adequate detecting level is regulated with a variable resistor 34 connected to a terminal 33, by which the signal from the terminal 33 is inputted to the system 25. Thus the quantity of the electrostatic charge on the drum 8 is changed to increase or decrease the amt. of the toners to be stuck on the drum 8 by controlling the high voltage current to be applied to the electrifier in the above- mentioned way, whereby the sharp copies are obtained irrespectively of the humidity condition.

Inventor: KATO MINORU
IPC: G11B5/10
Filed: 1988-02-16
Abstract: PURPOSE:To fix a block member on a case more firmly and to heighten reliability for a magnetic head, by fixing the projecting part of the block member, and preparing a case member consisting of a material with melting point lower than that of the block member. CONSTITUTION:A solid shape mask block 2a is formed in advance by using the material with high melting point such as metal with comparatively high melting point (m.p. is 1,000-1,500 deg.C), for example, stainless steel, and is arranged at the position of a mask block 2'a. Next, the case 1a is formed by using the material with comparatively low melting point such as 'Delrin(R)' (m.p. of 250-350 deg.C). After that, the case 1a and the mask block 2'a can be fixed without using a bonding agent by cooling and fixing the material with low melting point. Therefore, by cooling and fixing the material with low melting point after forming the case 1a in which a welded material with low melting point is used, the mask block 2'a is fixed more firmly because the case 1a bites into the projecting part 2b.

Title: Forgery preventive formed body having string of punched holes to which information is imparted, and its read-discrimination
Inventor: KIMURA KENICHI
IPC: B41M3/14
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To increase the forgery preventive effect while normally being hard to recognize, and at the same time, facilitate a forgery discrimination by forming a large number of punched holes to impart specified information being linearly arranged along a straight line which becomes a reference for the arrangement of a string of punched holes, as the string of punched holes for separation. SOLUTION: (a), punched holes p at locations with equal intervals impart information '0', and punched holes q at locations shifted either to the right or left side from the punched holes p, e.g. at locations shifted to the right side, impart information of '1'. Also, a string of punched holes under another performing configuration (b), imparts information in such a manner that a wider interval w between punched holes is '1', and a narrower interval n is '0'. These strings of punched holes do not present a sense of incongruity as normal punched holes for separation as long as a difference amount for the intervals between punched holes is kept small, and in addition, by imparting a delicate shift, the forgery/alteration preventive effect can be increased. Also, when an easily stretchable base material such as paper is used, the configuration shown under (b) is preferable.
