Title: Method and device for carrying reversal film
Inventor: KAJI TOSHIKAZU
IPC: G03B1/00
Filed: 1994-02-28
Abstract: PURPOSE:To improve a correct rate in reading the information of reversal film without reducing the kind of write information. CONSTITUTION:The reversal film 100 on which the information is previously recorded corresponding to respective picture frames is carried along a carrying path 66 by carrying rollers 66A and 66B.

Title: Retrieving system for under-operation flag
Inventor: SHIMADA NORIO
IPC: G06F15/00
Filed: 1986-02-14
Abstract: PURPOSE:To process data while checking a group that is not set at zero even when a flag under-operation is retrieved, by displaying the real numbers so that the operating states of devices are previously checked within a group. CONSTITUTION:In a real number display area of an under-operation flag, +1 and -1 are designated to the real numbers when the flag of the opposite group is turned on and off, respectively. Thus the number of display areas are coincident with the number of working devices. As a result, a conventional key flag is turned off when the value of the real number display area is set at '0' and then turned on when said value is equal to >=1 respectively. In such an example, the retrieval of the under-operation flag can be passed since the real number display areas 52 and 54 show '0' respectively.

Title: Powder applying device
Inventor: TSUDA MASAYUKI
IPC: G03D13/00
Filed: 1991-02-26
Abstract: PURPOSE:To provide the powder applying device which does not deform a supplying roller and does not eventually generate unequal application even if the device is not operated over a long period of time. CONSTITUTION:A stepping motor 24 operates and a movable shaft 23 revolves accordingly when a power source of an image forming device or the like provided with the color developer applying device 1 is turned on. Consequently, an L-shaped bearing 21 moves toward a plane bearing 22 and the color developer carrying supplying roller 9 simultaneously moves accordingly. The stepping motor 24 is stopped by a sensor 25a if a color developer roller 5 and the color developer supplying roller 9 come into contact with each other by having a certain determined area. Consequently, the carrying roller and the supplying roller can be held in the contactless state while the device is not used over a long period of time and, therefore, the deformation of the supplying roller does not arise.
