Patent number: 6586714Abstract: The microwave oven includes an infrared sensor for detecting the temperature of a food within a heating chamber. The infrared sensor has a field of view within the heating chamber. The infrared sensor is capable of moving the field of view. The food is often placed in the central region of the heating chamber.

Patent number: 5986247Abstract: A high frequency heating device having a switching member screwed into a screw hole formed in a flange and fixed to the exterior. When the exterior is fixed to the body, a through-hole formed at that portion in the rear plate of the body through which the switching member passes is too large for the switching member. Thus, while the switching member is fixable to the exterior, the switching member cannot be fixed to the body onto which the exterior is not mounted. Therefore, a high frequency heating device can be provided, wherein an exterior switch more surely keeps the power supply circuit open when the exterior is removed.Type: GrantFiled: July 28, 1997Date of Patent: November 16, 1999Assignee: Sanyo Electric Co., Ltd.Inventors: Hiroki Hayashi, Hideki Yamauchi, Junji Murata, Kazuhiko Kawamura, Keiji Harada

Patent number: 5358909Abstract: A field-emitter having stable electrical properties, a long service life and a very small electron emission voltage is provided. The cathode of the element has a strongly sharpened projection at the tip end, and a smooth connection between the projection and the body portion. In the method of manufacturing the elements, cathodes are produced with a high reproducibility by using a mold produced by forming concave portions in the silicon and oxidizing the layer thereon, whereby the spacing between the cathode and the gate electrode is determined by the thickness of the silicon oxide layer, and the position of the cathode is determined by the silicon oxide layer embedded in the silicon substrate, by using an etching stop method based on an electrochemical etching process.Type: GrantFiled: February 26, 1992Date of Patent: October 25, 1994Assignee: Nippon Steel CorporationInventors: Gen Hashiguchi, Satoshi Kanazawa, Kazuhiko Kawamura, Hikaru Sakamoto

Patent number: 5323470Abstract: Methods and apparatus for automatically tracking the position of a moving object in real time, particularly the face of a person who is being fed by a robotic system, is disclosed. The object can be tracked by comparing a prestored object model image with the current image of the object using the square-distance criteria. The search area can be limited to a region in which the face is most likely to be found and the prestored object model image can be limited to robust points. The method can include motion prediction, including both continuous motion and sudden motion, such as the motion cause by a person sneezing. Alternatively, a computationally efficient approach employing a one-dimensional algorithm can be used.Type: GrantFiled: May 8, 1992Date of Patent: June 21, 1994Inventors: Atsushi Kara, Kazuhiko Kawamura

Patent number: 5285381Abstract: A control system for rapid fault tolerant control of a multiple control-point apparatus is disclosed. The system comprises: a host subsystem acting as a user interface; a plurality of control-point actuators; a master controller subsystem which receives initialization data from the host terminal and which generates behavior commands; and a control-point controller subsystem which receives behavior commands from the master controller subsystem and generates control-point actuator commands. The control-point controller subsystem is made fault tolerant by using a plurality of control-point processors connected to control-point interfaces through a programmable crossbar switch such that if any of the control-point processors develops a fault, the crossbar switch will connect one of the other control-point processors to the control-point interface previously serviced by the faulty control-point processors.Type: GrantFiled: September 9, 1992Date of Patent: February 8, 1994Assignee: Vanderbilt UniversityInventors: Moenes Iskarous, Kazuhiko Kawamura

Patent number: 5118568Abstract: A steel cord for reinforcing rubber. It is made of three steel filaments all having different diameters from one another. The small-diameter and medium-diameter ones of the three filaments have internal stresses adapted to be released when the cord is cut at both ends thereof. Owing to these stresses, the diameter of the cord is adapted to increase after it is cut at both ends. At the same time, the medium-diameter and small-diameter filaments retract inwardly from the ends of the large-diameter and medium-diameter ones, respectively.Type: GrantFiled: April 4, 1990Date of Patent: June 2, 1992Assignees: Sumitomo Electric Industries, Ltd., Sumitomo Rubber Industries, Ltd.Inventors: Kenichi Okamoto, Hidekazu Nakata, Kazuhiko Kawamura
