Title: Building driving cotter
Inventor: BABA EIHACHIROU
IPC: E04B1/48
Filed: 1994-12-19
Abstract: PURPOSE: To make it possible to prevent the occurrence of cracks in building column, etc., by arranging a large number of projected threads inclined and extended to the axis of a building driving cotter concerned along a spiral piece in a row monolithically on the circumference of the upper part of the column so as to keep conformal intervals. CONSTITUTION: Building driving cotters 1 are driven into cotter driving holes bored in generally building wooden column, beam, girder, etc. Generally, metal plate-like joint devices driven into joint device slits cut in the building column, beam, girder, etc., pass through a column cotter hole for the joint devices and are driven from an inverted head cut cone section 3 side while tapping the end face 2b on the opposite side of the inverted head cut cone section 3 side of a column section 2 so that they are fixed to the column, beam, girder, etc. After the joint devices are driven, since a cotter driving hole having the same inside diameter as the original outside diameter ϕ 1 of the column section 2 of the driving cotter 1 (the outside diameter of part other than an upper part 2a) can be considered as an object, the driving cotter 1 can be driven in such a cotter driving hole.

Title: Method and apparatus for detection of fracture in shape of object to be detected
Inventor: TAKEGAWA YOSHIKIYO
IPC: A23L11/00
Filed: 1999-11-05
Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for the detection of a fracture, in which the fracture in the shape of a rectangular parallelepiped-shaped object to be detected such as Tofu, Konnyaku or the like is detected mechanically before the object to be detected is housed in a package container. SOLUTION: An object T to be detected, which is conveyed to a detecting position by a conveyance means 11 and a conveyance means 12, is irradiated with light so as to obtain a luminous flux which aims the upper surface of the object T to be detected from the oblique upper part in a straight line to a direction at right angles to its conveyance direction. The line shape of the luminous flux is grasped two-dimentionally from the upper part of the detecting position. The shape is compared with the two-dimensional shape of a luminous flux obtained at a time when an object T to be detected in normal shape is irradiated,. As a result, a fracture in the shape of the object T to be detected is detected.

Title: Liquid crystal projecting display device
Inventor: TEJIMA YASUYUKI
IPC: G02F1/13
Filed: 1988-12-14
Abstract: PURPOSE:To prevent the decrease of contrast occurring in surface reflection by forming the exit face on the projecting lens side of a dichroic prism as a curved surface. CONSTITUTION:The generation of ghosts by the surface reflection of the dichroic prism 11 and the degrease of the contrast are prevented if the end face on the screen side of the dichroic prism 11 is formed as the curved surface. Namely, the luminous flux emitted from the point A and is passed through the dichroic prism 11 then through the projecting lens 15 and a stop 22 arrives at the screen like A'. The upper ray b1 and lower ray b2 of another luminous flux emitted from the point B arrive at the screen like B'. Since the exit surface consists of a concave surface 21, the luminous flux of an alternate long and short dash line and the luminous flux of a broken line are varied in direction. The luminous flux shown by the broken line is, therefore, partly shielded by the stop 22 and is thus prevented from arriving at the screen. The ghosts of the image projected on the screen and the decrease of the contrast occurring in the ghosts are prevented in this way.

Filed: 1993-11-22
Abstract: PURPOSE:To provide the correcting method for the eccentricity effect having a short index time and high position correction accuracy in a device rotating a sprocket and pitch-feeding a TAB tape. CONSTITUTION:The reference image pickup data at the rotation start position of a sprocket 2 and the readout image pickup data when a TAB tape is pitch- fed are compared in the preparation stage, and the displacement value of the TAB tape from the rotation start position is sent to a controller 20.

Title: Freshness keeping agent for food
Inventor: YAJIMA KOTOSHIGE
IPC: B65D81/28
Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To soften the sharp wasabi smell without losing antiseptic property of wasabi extract to prevent a taste of food from being lost by including bamboo extract or bamboo extract and tea extract in addition to the wasabi extract as constituents. SOLUTION: Bamboo extract or further tea extract is mixed in wasabi (Japanese horseradish) extract to be used as freshness keeping agent for food. For example, aqueous solution containing constituents of wasabi extract of 0.1 to 2%, bamboo extract of 1 to 5%, green tea extract of 3 to 5% and an appropriate quantity of alcohol is received as it is, or the aqueous solution applied on non-woven cloth with 10 to 30 g/m<3> is received in a sealed container together with food. Thus compared with cases where the wasabi extract and the bamboo extract are independently used, higher freshness keeping function for food can be exhibited, while especially remarkable antiseptic ability can be recognized against fungus. In addition, wasabi smell scarcely occurs, and food itself can be deodorized.

Filed: 1998-10-20
Abstract: PROBLEM TO BE SOLVED: To enable a player to easily grasp the difference of elevation from a fixed view point by setting an arbitrary point in a three dimensional virtual apace as the reference point and placing a semitransparent filter at a pint at a prescribed distance from the set reference point. SOLUTION: A reference setting means 1 is set an arbitrary point in a three dimensional space as the reference point P. A semitransparent filter S is placed by a filter placing means 2 onto a point at a prescribed distance from the set reference point P. When the semitransparent filter S direction is viewed from the set reference point P in that state, a matter at a point at more than the prescribed distance from the reference point in the elevation direction, i.e., upward or downward direction, is viewed through the semitransparent filter causing the display image of the matter is masked by the semitransparent filter. Thus a player can easily grasp the difference of elevation from a fixed view point, on sensor switch 35. Thus a player can enjoy a game doing exercises.
