Filed: 1978-02-18
Abstract: PURPOSE: To prevent damage of contents by gradually discharging the content, reducing the drop head of the content, and forming a cushion member on the transfer surface so as to prevent collision and trembling on the inversion of the content.  
     CONSTITUTION: A transfer conveyor 11 stop when two boxes 39 have come onto a holder table 33. With a motor 9 driven, an inversion frame 1 inverts 180° and stops there.

Title: Electric kitchen range
Inventor: KUBO YOSHINOBU
IPC: F24C7/06
Filed: 1988-01-28
Abstract: PURPOSE:To prevent increase of the temperature of a frame body and a gravy pan and to facilitate cleaning, by a method wherein an approximately latticeform frame body holding a heater is pivotally supported to the inner side of a top plate, a hole part is formed in the inner side of the peripheral frame of the frame body, and approximately latticeform pot mount beds have a protrusion part inserted in the hole part and removably mounted to the frame body. CONSTITUTION:A pot is placed on each of heaters 2, 3, and 4, and with the heaters 2, 3, and 4 energized, an ambient temperature in the vicinity of the heaters 2, 3, and 4 is increased. High temperature air flows out through a space in a frame body 11 through convection, and heat is emitted to the outside. Thereby, a space between a gravy pan 9 and the frame body 11 is difficult to stay, and as a result, an increase in the temperatures of the gravy pan 9, the frame body 11, and the interior of a body can be decreased. Meanwhile, when gravy is erroneously split during cooking, the frame body 11 is rotated upward on a hinge part 10, and the gravy pan 9 can be removed for easy cleaning. Since approximately latticeform pot mount beds 16, 17, and 18 are also removably mounted, the beds can be removed and cleaned, resulting in the possibility to always keep a kitchen range in a clean state.

IPC: H04N1/40
Filed: 1995-02-06
Abstract: PURPOSE: To obtain a gesture recognition device which recognizes dynamic and static gestures from an image fetched by an image input device and interme diate for input to a computer. CONSTITUTION: A low-level model-free recognition system for dynamic and static gestures uses linear histogram of a space orientation angle-to-generation frequency for the static gestures or a two-dimensional space time orientation histogram for dynamic gestures. In each case, the histogram constitutes the signature of gestures used for gesture recognition. For dynamic gesture detection, a three-dimensional space time map is merged or converted into a two-dimensional space time orientation histogram wherein the generation frequencies of orientation and movement are both graphed. The inputted dynamic gestures are matched with this display, i.e. template.

Abstract: PROBLEM TO BE SOLVED: To enable a solar cell of high performance to be manufactured by a method wherein a semiconductor thin film is formed on a heat-resistant substrate, and the thin film is heated, melted, and recrystallized into a polycrystalline semiconductor film in a nitrogen-containing inert atmosphere. SOLUTION: Powdered, lump or gaseous silicon is introduced as a material into a plasma generating section through a material feed section 3, a melt is deposited on a board and formed into a semiconductor film as it is cooled down at a certain cooling rate that is properly controlled by a board heating section 6. An exhaust system 7 is connected to a film forming section 2, and volatile components contained in material when a film is formed and solidified silicon are discharged out without adhering to the board 4. The atmosphere of the film forming section 2 can be controlled by the exhaust system 7 and an atmosphere gas control system 8.
