Patent number: 7989722Abstract: Disclosed is an illuminated switch device capable of effectively preventing light leakage between different light sources, thereby obtaining a good lighting quality, while reducing the overall size of the switch device. The illuminated switch device includes: a casing that has an open upper end and a partition wall provided therein and is formed on a bottom plate member having light sources and a push switch mounted thereon; and an operating body that has a light-shielding wall provided on the rear surface of an upper plate, is arranged so as to close the open end, and can be pressed. First and second illuminated regions to which light components are emitted from first and second light sources are provided on the upper plate. A protruding portion is formed at a leading end portion of a light-shielding wall, and a concave groove is provided at a leading end portion of a partition wall. The leading end portions are opposite to each other such that they can approach or separate from each other.Type: GrantFiled: October 6, 2008Date of Patent: August 2, 2011Assignee: Alps Electric Co., Ltd.Inventors: Anthony McCurdy, Takayoshi Hoshi, Toshio Imai

Patent number: 6735404Abstract: A remanufacturing method is disclosed for a process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, wherein the process cartridge includes first and second frames rotatably coupled relative to each other. The remanufacturing method includes (a) a separating step of separating the first and second frames; (b) a step of dismounting a developing roller mounted in the second frame; (c) a step of peeling off an elastic sealing member for providing a seal between the second frame and the developing roller; (d) a step of sticking a double coated tape on a seat on which the elastic sealing member has been stuck; (e) a step of filling developer into a developer accommodating portion of the second frame; (f) a step of mounting a developing roller to the second frame; and (g) a step of coupling the separated first and second frames.Type: GrantFiled: July 31, 2002Date of Patent: May 11, 2004Assignee: Canon Kabushiki KaishaInventors: Akira Higeta, Satoshi Yasuda, Takayoshi Hoshi

Patent number: 6181746Abstract: Decoding images encoded on MPEG requires I and P pictures to be held for a long period of time for B picture reproduction, resulting in a greater amount of memory capacity necessary. This image data decoding apparatus has a reverse quantization section, a reverse DCT section, a sequence managing section, a motion compensating section, and a DRAM control section. Reverse quantization and reverse DCT operations are performed on input encoded image data. The sequence managing section determines the type of input pictures and detects sequences where more than one B picture is continuously input. I and P pictures are necessary for the decode operation of B pictures, so they are held in any frame bank. However, a B picture which has already been displayed is unnecessary, so one bank is shared by two B pictures which are continuously input. This results in a smaller number of necessary banks.Type: GrantFiled: January 27, 1997Date of Patent: January 30, 2001Assignee: Rohm Co., LTDInventor: Takayoshi Hoshi

Patent number: 5943102Abstract: An image data decoding and displaying apparatus is equipped with a decode map set for storing decoded data for every frame into an empty areas in a memory. This set contains a plurality of maps each describing a memory area for a frame. A map is changed by a unidirectional counter for every start of a decode operation in frames. A display map set is also provided with a bidirectional counter. Normally, these two counters are incremented every time a frame is decoded and displayed, respectively, so the same maps are referred to from decode operation and display operation. In the display operation, bidirectional counter is decremented by one if data is not decoded in time for display, so that a map for an immediately preceding picture is referred to. In such a case, the previous picture is displayed twice in place of the current picture. Display transition from the current picture to the previous one is performed smoothly changing maps consistently for these pictures.Type: GrantFiled: March 21, 1997Date of Patent: August 24, 1999Assignee: Rohm Co., Ltd.Inventor: Takayoshi Hoshi
