Title: Seat device equipped with leg rest
Inventor: KAWASE HIDETOSHI
IPC: A47C1/035
Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To provide a seat device equipped with a leg rest, which is capable of preventing the shortening of the leg rest, and holding the entire lower leg of a user. SOLUTION: An assistant rest 6 connected to a leg rest 5 housed below the front end of a seat frame 4 is housed by being raised and inclined from its support shaft 8 upward toward a rear side and, compared with a conventional seat device where an assistance rest is housed by being lowered and inclined from a connecting portion with a leg rest downward toward a rear side, the length of the leg rest 5 is larger. In addition, when the leg rest 5 is developed and expanded, the front end portion of the seat frame 4 is raised by a seat vertical moving mechanism 9, and thus the assistance rest 6 developed and expanded by the leg rest 5 is passed through a position away from a floor surface, and accordingly the assistant rest 6 is formed to be large in length. Thus, the entire lower leg portion of a user including a foot tip is held by the leg rest 5 and the assistant rest 6.

IPC: G06T5/00
Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To obtain a binary image without generating two or more sheets of input images nor deleting an object out of a single sheet of input image. SOLUTION: A histogram generation part 16 receives the digital image signals of input images sent from an A/D conversion part 12 and generates the histogram data on the input images including an object and its background. A histogram generation part 20 receives the histogram data including the object and the background from the part 16 and generates the histogram data on only the background. On the other hand, a histogram generation part 22 subtracts the histogram data on only the background received from the part 20 from the histogram data including the subject and the background received from the part 16 and generates the histogram data on only the subject. The part 22 also generates the data having almost the largest luminance value as its threshold from the histogram data on only the subject. An image binarizing part 24 slices the histogram data on the subject and the background received from the part 16 by the threshold data received from the part 22 to generate the binary digital image signals of only the subject and output these image signals.

Title: Agc circuit for television receiver
Inventor: SAKAI YUJI
IPC: H04N5/52
Filed: 1988-12-28
Abstract: PURPOSE:To prevent a vertical sag from occurring by decreasing AGC response speed in the vertical blanking period of a video signal by setting the AGC response speed variably. CONSTITUTION:When the movable contact 14a of a mode change-over switch 14 is switched to a fixed contact 14b on a conversion synchronizing signal Vs* side, a conversion synchronizing signal Vs* in which a vertical synchronizing signal Vs is compacted or expanded is supplied to the connection terminal 16 of an AGC filter 35. Therefore, the time constant of the AGC filter 35 is switched to a short side in a section T1 where the level of the conversion synchronizing signal Vs* is low, and the time constant is switched to a long side in the section where the level of the conversion synchronizing signal Vs* is high. In such a way, the level can be maintained at a stable level even when a input electric field level is fluctuated quickly, and also, the attenuation of the level due to the vertical sag can be eliminated even in the section in the neighborhood of a vertical synchronizing pulse F.

SiC is mixed with the silica-type glass for the purpose of improving the oxidation-inhibiting action to a greater extent. In order to prevent intergranular oxidation at the slab surface, the thickness (d) of the oxide inhibiting film is regulated to >=0.1 mm. Moreover, in order to improve adhesion to the slab, drying time (t) is set up so that it satisfies logt>=0.6×d-1.0.
