Patent JP-S631558-A (JP)
Title: Image printer
Inventor: CHIBA KAZUHIRO
IPC: H04N1/405
Filed: 1986-06-20
Abstract: PURPOSE:To reduce an effect of a printing rate in the previous line and improve the printing state of a low density by making the heat generation intermittent at the border of adjoining pixel and forming a single pixel with a plurality of dispersed color-developing dots especially in low-density printing. CONSTITUTION:An output signal C4 of a counter is selected as an ON/OFF signal for a printing head to represent a time elapse in a system control 10 by comparing data obtained through conversion by an address conversion means 1 which data C4 using a comparator 106. The data C4 is a value which increases monotonously from 0-15 every printing in a single scan, and this value is converted by address conversion means 1. After conversion, when data C10<=C5 (C5 represents data converted by a density conversion means 105), the printing head is set to 'ON' state. Because of 'OFF' signal provided at the beginning and end of a single line, a cooling time is provided between dots, and a heat historical density nonuniformity can be avoided. Therefore, the nonuniformity does not appear except when a printing of maximum density is performed continuously, thus improving the printing significantly.

Filed: 1988-06-13
Abstract: PURPOSE: To improve the stability (installing property) of a bone support member to a bearing surface by making the bone support member supported by a pair of holding means rockable to a stem body. CONSTITUTION: A stem body 1 has an emoshi-like (headgear worn by nobles in the past) projection 2, and a neck part 4 protruded upward from a flat upper end surface 3. The neck part 4 has a ring-like projection 6, and the lower surface 7 of the projection 6 is formed into a protruding spherical form. Further, the neck part 4 has a groove-like constriction part 8 between the lower surface 7 and the upper end surface 3 of the stem body 1. A bone support member 9 is formed into a hose shoe form by removing the central part of a disk member in U-shape, so that the recessed part 1 of the bone support member 9 is supported by the protruding spherical surface 7 of the corresponding ring-like projection 6. The bone support member 9 can self-regulate the inclination by these spherical parts 7, 11 so as to make contact with the whole bearing surface of a cut surface of the femur.  Thus, the load through a joint can be effectively transmitted without being much influenced by the inclination of the cut surface.

IPC: G03B19/12
Filed: 1994-06-02
Abstract: PURPOSE:To facilitate a proper visibility correction even in a different observing state by selecting one of data previously stored in a storage part and driving the element of a part of an optical system through the use of the selected data. CONSTITUTION:An observer side (an eyeball and its peripheral part,) is irradiated with luminous flux from a light source 20 and the reflected light from the observer side is used to detect the observing state of the observer by a detecting part 23.

Title: Device and method for electronic authentication of text, and recording medium recording program for electronic authentication of text
Inventor: INAGAKI HIROTO
IPC: G09C5/00
Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To provide a text electronic authentication device which can properly authenticate an electronic text represented by an HTML text and can fetch buried authentication information, by burying the created ciphered electronic authentication information in the text, and burying the ciphered electronic authentication information so that it does not disappear even though the text with the buried information is edited. SOLUTION: A text authentication information burying part T-6 buries text authentication information generated in a text authentication information generating part T-5 in an inputted text. In this case, the text authentication information is buried distributed in the text so as to be durable against such changes as cutting and deletion of the text. A text authentication information fetching part T-7 fetches the buried text authentication information from the text in which the text authentication information has been buried for authentication or the like. Thus, since the text authentication information is buried as the undecipherable ciphered electronic authentication information, the proper authentication can be provided.

Abstract: PURPOSE:To prevent a malfunction which is caused by an insect by generating an infrared beam about 3mm above a tube surface, performing position detection as to one axis at least twice, and regarding the same coordinate values as plane coordinates when the same coordinate values are detected. CONSTITUTION:The position detection of one axis, e.g. an X or Y beam is performed at least twice and when 1st and 2nd values are equal, they are regarded as the detected value of the beam position of another axis and regarded as the determined correct plane coordinates, since a fly, etc., never interrupts the same beam. A light emitting diode 11 and a phototransistor 12 are so arranged as to generate the infrared beam about 3mm above the tube surface so that the beam between both is not interrupted by an insect such as the fly on the tube surface of a CRT 10. Consequently, the problem of parallax is not caused and the malfunction which is caused by the fly, etc., is prevented.
