Title: Method for driving electro-chromic display element
Inventor: KAWAI TETSUO
IPC: G09G3/16
Filed: 1988-03-07
Abstract: PURPOSE:To prevent wrong confirmation of information so as to improve the reliability of the title element by temporarily adding coloring pulses to all segments during the decoloring pulse period before a displaying content is updated. CONSTITUTION:In case displaying numerals are successively updated in the order of (8)   (2)   (1)   (next numeral), temporary coloring pulses Ps are impressed upon all segments a-g during the impressing period of decoloring pulses Pd before each updating, namely, in the time t1. Namely, pulse impression is performed in the order of decoloring pulse Pd   coloring pulses Ps  decoloring pulses Pd in the decoloring pulse period t1 and all segments a-g are uniformly subjected to the decoloring process after a coloring process before updating. Therefore, the difference in the degree of decoloring before updating is averaged even if the coloring and decoloring history of each segment is difference from each other. Accordingly, wrong confirmation of a display caused by uneven decoloring can be prevented.

Title: Cassette disk
IPC: G11B23/03
Filed: 1992-03-12
Abstract: PURPOSE:To record information on an optical disk cheaper than the case of using the conventional optical disk capable of optical recording by integrally fixing a memory unit with a reproducing only optical disk cassette. CONSTITUTION:An optical disk 10 is referred to a reproducing only optical disk, and is fixedly housed in the cassette 102. A shutter 104 is usually closed, and is moved by a setting operation in the direction of an arrow A when the disk is set in a disk drive, so that a window 107 for an optical pickup and a window 108 for contact points on the side of the memory unit are simultaneously opened. By using this cassette deck, because of its interchangeability with the conventional reproducing only disk, data and software hitherto available can be used as they are. Then, since neither fingerprints at the time of handling nor dust is stuck to the optical disk itself, the reliability of the optical disk in reproducing is improved, and moreover a fear of losing the memory unit 103 due to detaching it from the cassette at the time of carrying is eliminated.

IPC: G09F9/37
Filed: 1999-03-02
Abstract: PROBLEM TO BE SOLVED: To provide a method of improving a gylicon sheet which is one of electric paper. SOLUTION: This invention relates to an electric paper sheet using a pattern of conductive electric charge holding islands 306 mounted on an external side of a 1st plane 302 of a thin layer used for capsulizing a gylicon sheet 300. A 2nd capsule layer 304 can also be coated with a conductive material or made of a conductive material, but does not need to be patterned. The gylicon sheet 300 and two sheets of the capsule layer 302, 304 constitute a sheet of gylicon electric paper on which a picture can repeatedly be written or erased. The electric charge holding islands 306 where the 1st capsule layer 302 has been patterned receives electric charges from an external electric charge moving device.  Also after the electric charge moving device is removed, the conductive electric charge holding islands 306 holds the electric charges, and applies an electric field to the gylicon sheet 300 enough to cause a change in the picture.

Title: Image forming device
Inventor: TAKANE RYOTA
IPC: B65H43/06
Filed: 1999-03-02
Abstract: PROBLEM TO BE SOLVED: To eliminate waste of recording paper or the like to improve working efficiency by providing a controller for stopping image forming operation after completing one cycle during execution when the number of sheets of recording mediums over a fixed number are loaded on a paper discharge tray. SOLUTION: When the total number of sheets is judged to be over the fixed number, namely, when stack over is generated, copying operation is stopped when recording paper discharged into a paper discharge tray 60 during copying operation exceeds the fixed number. In this case, a controller computes a time up to stopping the copying operation. The computed time is displayed as the time up to copy stopping on a display for information. Or the time up to copy stopping is added to the beginning time of the copying operation to be displayed as the copy stopping time. After displaying these times on the display, copying operation is begun. Hereby, a user is unnecessary to pay attention to the copying operation condition for confirmation, waste of a time is eliminated, and the user can devote oneself to the other work.

Title: Communication controller testing system
Inventor: OKAWA TORU
IPC: H04L69/40
Filed: 1986-03-12
Abstract: PURPOSE:To test the interrupt operation of a channel adapter without connecting a host computer by building a test program in a communication controller. CONSTITUTION:Before execution of the test, a simulator handler 24 sets a channel adapter (CA) 21 to the test state by the indication from a main program 26. The control is transferred from the main program 26 to a test program 25, and the transmission request of data is issued from the test program 25. The main program 26 transfers to control to the simulator handler 24 for the purpose of starting the operation of CA 21. At the time of receiving a transmission end instruction, the CA 21 generates an interrupt to the main program 26 again. When confirming that data transmission is terminated, the simulator handler 24 reports it to the main program 26 that the transmission operation request of the test program 24 is terminated.
