    Abstract: In a semiconductor device, a plurality of semiconductor chips included in an upper-arm circuit are connected in parallel between a pair of upper-arm plates, while a plurality of semiconductor chips included in a lower-arm circuit are connected in parallel between a pair of lower-arm plates. In each of the arm circuits, the plurality of semiconductor chips are arranged in a direction perpendicular to a direction in which emitter electrodes and pads are arranged, the pads are disposed on the same side of the emitter electrodes, and signal terminals extend in the same direction. A series-connecting part between the upper- and lower-arm circuits includes a joint part 20 continued to respective side surfaces of the corresponding upper- and lower-arm plates. Each of inductances of respective parallel-connecting parts of the upper- and lower-arm plates which connect the semiconductor chips in parallel is smaller than an inductance of the series-connecting part.

  • Publication number: 20190028776
    Abstract: To make it possible to easily use video data of raw data of a high frame rate input from a single-chip camera in a server system that is different from an AV server system in which an AV server itself is included. First AV clip data is obtained by performing a compression encoding process to raw data of a high frame rate input from a single-chip camera and is written in a storage. The raw data of the high frame rate is obtained by reading the first AV clip data from the storage and processing a compression decoding process on the first AV clip data, video data of a high frame rate is obtained by performing a demosaic process on the raw data, and second AV clip data is obtained by performing a compression encoding process on the video data and is written in the storage. The second AV clip data is read from the storage and transmitted to a second AV server system that is different from a first AV server system in which an AV server itself is included.

  • Patent number: 9434579
    Abstract: An exemplary roller guide assembly for an elevator device comprises a shaft supporting a roller for engaging a guide rail, a shaft support member that receives the shaft therein, and a member inserted between the shaft and the aforementioned shaft support member. According to this invention, because the shaft is supported by the shaft support member via the elastic member, when the rollers are biased in the horizontal direction by the guide rail, the member limits the shaft from turning relative to the shaft support member.

  • Patent number: 9382098
    Abstract: An elevator car (1) which moves vertically along the hoistway is provided with a roller guide assembly (3) guided by a guide rail (2). The roller guide assembly (3) is provided with a horizontal fixing shaft (8) which is fixed to a base member (6) and rollers (5a, 5b, 5c) which are supported by the horizontal fixing shaft (8). The rollers (5a, 5b, 5c) are each provided with a roller outer circumference section (10), a rolling bearing (9), an annular rubber (11), and an inner cylinder (12). The configuration eliminates the need for a conventional spring or a conventional damper mechanism because the rubber (11) deforms elastically.

  • Patent number: 9359178
    Abstract: A detector for an electromagnetic brake, for example used in an elevator system, that, by quantitative judgment, determines whether the brake force of the electromagnetic brake is appropriate. Load cells for detecting the recovery forces of brake springs are arranged between brake springs, which energize brake arms with brake shooes installed on them toward the side of brake wheel, and spring sheets, which hold brake springs in a compressive deformed state, and, at the same time, judgment part judges whether the brake force of electromagnetic brake 4 is outside a prescribed normal range based on the outputs of load cells. If the brake force of electromagnetic brake is outside the normal range, judgment part sends a signal, for example to a monitoring center.

    Abstract: An apparatus and method for generating a stereoscopic pointer. Position information designates a position of the stereoscopic pointer, including the depth direction of the stereoscopic pointer. Horizontal pointer position signals are generated based on the position information. The horizontal position of the pointer is set in left and right channels to a horizontal position shifted so as to correspond to a parallax of the position of the stereoscopic pointer in the depth direction. The stereoscopic pointer is displayed based on the horizontal pointer position signal.

  • Patent number: 8817887
    Abstract: Disclosed herein is an information processing apparatus that performs a process of splicing encoded streams together at a splicing point, the apparatus including: control means for determining a section to be subjected to re-encoding in the encoded streams; decoding means for decoding the encoded streams to generate baseband signals; and encoding means for encoding an edited baseband signal generated by splicing the baseband signals generated by the decoding means together at the splicing point to generate an edited encoded stream. The control means provisionally determines a first section to be subjected to re-encoding in first and second encoded streams to be spliced together at a first splicing point. When a second splicing point exists in the first section or a predetermined section that follows the first section, the control means determines a second section to be subjected to re-encoding based on the second splicing point.
