Patent number: 6674872Abstract: A pair of lead wire drawn from a voice coil is fixed to a land portion of a pair of terminal member by thermo-compression bonding. The pair of terminal member is integrally formed with the frame by insert molding. The frame made of synthetic resin has a pair of circular holes on the back side of the land portion to expose the land portion to the back space of the frame. In thermo-compression bonding, a supporting jig is pressed against the back side of the land portion via the circular hole. Thereby, generated heat is immediately transmitted to the supporting jig, preventing melting part of the frame around the land portion. Pressing force of a thermo-compression jig is received by the supporting jig, preventing sinking of the land portion in the frame.Type: GrantFiled: May 21, 2002Date of Patent: January 6, 2004Assignee: Star Micronics Co., Ltd.Inventors: Naohiro Fujinami, Fuminori Moritake, Tomoyuki Sato

Publication number: 20020175021Abstract: The diaphragm is supported by the frame at the outer edge thereof. The pair of terminal members is mounted on the frame, and a pair of lead wire drawn from the voice coil is fixed to the land portion of the terminal member for electrical continuity. Since the land portion is disposed on the upper side of the frame, fixation of the lead wire can be performed without turning the frame upside down. This simplifies the manufacturing process of the speaker and also prevents a breakage of the lead wire that conventionally happens when the frame is turned upside down. Further, this prevents the operator from touching the lead wire since no part of the lead wire is exposed outside the frame after the fixation.Type: ApplicationFiled: May 9, 2002Publication date: November 28, 2002Applicant: STAR MICRONICS CO., LTD.Inventors: Fuminori Moritake, Shigeru Sugiyama, Naohiro Fujinami, Tomoyuki Sato, Yoshio Imahori

Publication number: 20010055318Abstract: FIG. 3B shows buffer occupancy rate of a transport stream buffer 21 when a TS packet is transferred to the transport stream buffer 21 having a transport rate Rt and a leak rate Rx. A time T1 during which the buffer occupancy rate of the transport stream buffer 21 increases and a time T2 during which the buffer occupancy rate of the transport stream buffer 21 decreases are expressed by (Rt−Rx)×T1=Rx×T2 and T1=(188×8)/Rt. A time T is T=T1+T2=(188×8)/Rx. Therefore, the time T is equal to a time T′ shown in FIG. 3C. Thus, when a TS packet is transferred in a cycle of the time T′, the transport stream buffer 21 will not overflow and the transport stream buffer 21 becomes empty at least once a second, whereby simulation for the transport stream buffer 21 is not required in the simulation for the T-STD model.Type: ApplicationFiled: April 2, 2001Publication date: December 27, 2001Inventors: Koji Obata, Noriaki Oishi, Tomoyuki Sato, Hajime Nitta, Kiyoshi Ota

Patent number: 6324216Abstract: An encoder considers a frame representing a picture as comprised of areas. For each area, the encoder decides which of frame-based or field-based orthogonal transformation will be most efficient at reducing spatial redundancy in that area. For each area, the encoder decides which of frame-based or field-based predictive encoding will be most efficient at reducing temporal redundancy in that area. The encoder encodes each area of the picture frame using the most efficient orthogonal transformation technique and using the most efficient predictive encoding technique to produce an encoded signal. A decoder decodes the encoded signal. The encoded signal is recorded on a recording medium, transmitted over a transmission channel, or broadcast.Type: GrantFiled: May 30, 1995Date of Patent: November 27, 2001Assignee: Sony CorporationInventors: Katsuji Igarashi, Jun Yonemitsu, Yoichi Yagasaki, Yasushi Fujinami, Tomoyuki Sato, Motoki Kato, Teruhiko Suzuki

Patent number: 5840104Abstract: A canister structure for absorbing fuel vapor in the fuel tank and supplying the fuel vapor into the engine together with purge air is provided. The canister structure includes a canister body filled up with absorbents for absorbing the fuel vapor, a purge pipe connected to the canister body for introducing the purge air into the canister body and a separator for removing moisture contained in the purge air. To the separator, the purge pipe is connected downwardly. The separator is provided on the bottom side with an air inlet of which diameter is larger than that of the purge pipe. With the above-mentioned arrangement, since the separator is so formed as to have a diameter larger than that of the purge pipe, it is possible to reduce a flowing speed of the purge air by means of the separator, so that moisture contained in the purge air can be trapped and eliminated by the separator certainly.Type: GrantFiled: December 18, 1996Date of Patent: November 24, 1998Assignee: Nissan Motor Co., Ltd.Inventors: Takashi Hashimoto, Tomoyuki Sato, Junichi Hanai, Kei Orita

Patent number: 5539466Abstract: An apparatus for coding a moving picture in which one frame is comprised of two fields, includes a coder such that, with respect to all blocks in a frame, the odd field (the first field) and the even field (second field) are divided into blocks, thus permitting motion prediction of the second field from the first field, a coder means adapted for switching, every macro block, whether or not a frame is divided into the first field and the second field to generate block data to adaptively switch these coders every frame, thereby making it possible to obtain a picture of a high picture quality with a lesser quantity of information, to reduce the scale of hardware, and to reduce the capacity of a decoder.Type: GrantFiled: September 26, 1994Date of Patent: July 23, 1996Assignee: Sony CorporationInventors: Katsuji Igarashi, Tomoyuki Sato

Patent number: 5475435Abstract: In an encoder, an input picture of a non-interlace structure is sampled by down sampling to form an interlace picture, and the interlace picture is encoded. The encoded data are decoded to form an interlace decoded picture, and the interlace decoded picture is sampled by up sampling and utilized as a predictive picture upon encoding of the non-interlace input picture. In a decoder, a bit stream corresponding to an interlace picture of a low resolution is decoded into an interlace decoded picture. The interlace decoded picture is sampled by up sampling and is utilized as a predictive picture upon decoding of a bit stream corresponding to a non-interlace picture of a high resolution.Type: GrantFiled: October 28, 1993Date of Patent: December 12, 1995Assignee: Sony CorporationInventors: Jun Yonemitsu, Katsumi Tahara, Tomoyuki Sato
