Inventor: KOBAYASHI AKIHIKO
IPC: G02B5/18
Filed: 1998-10-19
Abstract: PROBLEM TO BE SOLVED: To effectively use diffraction grating areas and to obtain high security making forgery and imitation difficult by dividing a cell into plural areas and making different a main diffraction grating area in an arbitrary shape and diffraction grating areas which are formed at its periphery without a gap. SOLUTION: The cell is divided into the plural areas and the main diffracting grating area in the arbitrary shape and the diffraction grating areas which are formed at its periphery without a gap are made different. For example, the shape (dot) of the cell is circular and has an inside area of a diffraction grating in a star shape as a main pattern and an outside area formed of a diffraction grating different from the diffraction grating inside the star between the circle and star; and the diffraction grating inside the star is a horizontal diffraction grating and the diffraction grating outside the star has a 45 deg. angle (a). When the mean length of the longitudinal and lateral dimensions of the cell is <=300 μm, it is very difficult to recognize the shape with the naked eye and thus speciality is added to an array of cells to obtain high forgery preventive effect.

Title: Picture area discriminating device
Inventor: OBATA MASATO
IPC: H04N1/40
Filed: 1991-10-17
Abstract: PURPOSE:To accurately discriminate whether a picture is a character picture or a dot picture with a small circuitry by automatically discriminating whether the picture is a halftone picture or a binary picture as to each area on an original in order to implement preferred processing in response to kinds of the pictures. CONSTITUTION:When a photosensing drum 3 is rotated, the surface of the drum 3 is uniformly charged with a high potential by energizing an electrifying charger 24 by activating a charger 24 and irradiated with a laser beam modulated by a binary signal in response to a picture to be recorded. Thus, the electrostatic latent image having a potential distribution in response to an image to be recorded is generated on the charged face of the drum 3 receiving the laser beam in this way and the electrostatic latent image is changed into a visual image by sticking toner thereto. Then the image is transferred onto transmission paper supplied from paper feed cassettes 4, 5 by the activation of the charger 14 and the paper is discharged to a tray 22 by a fixing device 23. That is, whether a picture is a dot picture or a non-dot picture is discriminated and pattern matching processing is simplified.

Title: Database managing device, database system, and recording medium
Inventor: MORI JUNJI
IPC: G06F21/62
Filed: 1999-10-19
Abstract: PROBLEM TO BE SOLVED: To cipher data while making a specific data item in a database higher in security than other data items. SOLUTION: A database stored in an external database storage device 18 is read out through a database I/F 17. Here, data of prescribed column items of the database are ciphered by using a column key which is common to the column items by referring to a key specification table 16c and data of other column items are ciphered by using row keys which are unique by rows as items which should be high in security. Further, the row keys are ciphered with a basic key by referring to a basic key storage part 16b and stored in a ciphered data storage part 16d together with the ciphered database. Thus, the ciphering is carried out while the keys are made different by the rows and the key used to cipher the column items is reciphered with another key to make it difficult to decipher the key, thus actualizing high security.

Title: Switching mechanism of vacuum valve
Inventor: SUZUKI MASAMI
IPC: H01H3/46
Filed: 1990-10-31
Abstract: PURPOSE:To remove unnecessary force applied to a movable electrode to make it possible to smoothly drive the electrode by making a spacer lie between a movable bar and a driving lever and regulating extension of a spring at the time of open driving to eliminate an energizing force applied to a driving lever. CONSTITUTION:A cylindrical spacer 36 is slidably inserted in between a pushed plate 37 and a pushing plate 19. The spacer 36 can be tilted on the curbed portions 21a, 21b of movable plates 20a, 20b. In the case a vacuum valve 14 is opened, when the driving shaft 22 of a revolving insulator 23 rotates so that the curved portion 21a pushes the plate 37 by means of the spacer 36, the energizing force of the spring 18 is never applied to the curved portion 21b. Resultantly, a movable bar 15 is, therefore, never pulled up by the plates 20a, 20b; as a result, an unnecessary force applied to the movable electrode in the vacuum valve can be removed, so that it can be smoothly driven.
