Title: Method for embedding information in three-dimensional form, method and device for extracting information embedded by the same and recording medium
Inventor: MIYAZAWA AKIHIRO
IPC: G06T19/00
Filed: 1999-09-30
Abstract: PROBLEM TO BE SOLVED: To utilize the parametric expression itself of a three-dimensional (3D) curved surface form without approximately expressing the 3D curved surface form as a polygon model, to embed information without changing the geometrical form of a portion corresponding to the original 3D curved surface form and to read this embedded information. SOLUTION: The 3D curved surface form expressed by the parametric expression is prepared (S1), and when that 3D curved surface form is not expressed as a trim curved surface, that form is expressed as a trim curved surface again (S2 and S3). then, the 3D curved surface form is extended (S4), and information is outputted for identifying the partial form added by extension (S5). The, information to be embedded is prepared (S6), and by changing a parameter for expressing the partial form added by the extension corresponding to the information to be embedded, the information is embedded in the said 3D curved surface form without changing the geometrical form of the portion corresponding to the 3D curved surface form before it has been extended.

Title: Method of detecting residual moisture in refrigeration cycle
Inventor: KAWAMURA KAZUO
IPC: F25B49/02
Filed: 1987-11-06
Abstract: PURPOSE: To reduce the manufacturing cost of a refrigeration cycle, i.e., a vacuum piping system, by detecting the degree of vacuum therein after evacuating it for a predetermined time and making a decision that residual moisture is present if the detected vacuum is lower than a preset reference level. CONSTITUTION: At the time of detecting residual moisture in a refrigerating cycle 1, an evacuation process is employed as a preprocess for charging refrigerant into the refrigerating cycle 1. When evacuation is effected through a vacuum pump 2, vacuum achievement is lowered by steam if residual moisture is present in the refrigerating cycle 1 and a decision can be made that residual moisture is present if the degree of vacuum after evacuation for a predetermined time is lower than a preset reference level. The decision can be made by providing only a vacuum gauge 5 and an alarm 7 in addition to an existing evacuator. Reliability of the refrigerating cycle can be enhanced because presence of residual moisture can be determined.

Filed: 1985-12-13
Abstract: PURPOSE:To obtain doubled resolution with same memory capacity by thinning out video signals and recording still pictures onto plural tracks in different time to apply band-compression to a spatial frequency to make it into a half and to simplify the circuit constitution. CONSTITUTION:Only an odd-th order of picture element is read on an odd-th order field scanning line and only an even-th order of picture element is read in an even-th order field scanning line and they are recorded on a recording medium, e.g., a magnetic tape. In case of readout from a frame memory, the picture element is read alternately from the odd-th order field scanning line and the even-th order of field line in the unit of picture elements. That is, the video signal corresponding to a picture element of the even-th order field scanning line next to the odd-th order field scanning line is interpolated to the video signal corresponding to the picture element absent from the odd-th order field scanning line, and the picture element of the next odd-th order is interpolated to the even-th order field scanning line conversely. The correlatively is very excellent in the thinning out and the resolution is improved without deteriorating the S/N.

IPC: H04N1/21
Filed: 1987-11-06
Abstract: PURPOSE:To efficiently perform selection work from first-order candidate images by reading out the DC component of each block after orthogonal transformation stored in a first hierarchical storage area. CONSTITUTION:After the first-order candidate image is selected by performing key word retrieval, the data set (for example, a1A-anA in an image A, and a1B-anB in an image B) of each image in an area (a) are read out sequentially, and after decoding being applied, they are stored in a first buffer memory and displayed on a display device sequentially. By applying such operation, since the first sequence component of an orthogonal transform coefficient after the orthogonal transformation represents the mean value of image elements in the block, it is possible to display a list of reduction images of 1/4 (original image size is 256X256). In such a way, the selection work from the first-order candidate images can be performed efficiently.

IPC: C07C37/50
Filed: 1989-10-31
Abstract: PURPOSE:To efficiently remove a tertiary alkyl group without selecting a reactor by using an arylsulfonic acid having an electron attracting functional group as a catalyst for detertiary alkylation reaction of an aromatic compound having a tertiary alkyl group and a hydroxyl group on an aromatic ring. CONSTITUTION:De-tertiary alkylation reaction of an aromatic compound (A) having a tertiary alkyl group and a hydroxyl group on an aromatic ring is carried out at 100-250 deg.C for 3-12hr using an arylsulfonic acid (B) having an electron attracting functional group as a catalyst therefor. When the compound A is phenols, sulfoisophthalic acid is preferably used as the compound B and when the compound A is a biphenol, nitrobenzenesulfonic aid is preferably used as the compound B. In the above-mentioned method, it is unnecessary to select the reactor, because a gas corrosive to metal is not generated and freedom for setting reaction conditions is large and the catalyst can be reused, because the compound B has high activity and is not decomposed under high temperature.
