Patent number: 8226532Abstract: A control apparatus for an automatic transmission having a rotation transmission mechanism for transmitting rotation of a prime mover mounted on a vehicle to a speed change mechanism, and an input clutch for controlling connection/disconnection of the transmitted rotation. The control apparatus includes a control portion that performs a neutral control including a release control that reduces rotation transmission efficiency, and an in-neutral control so as to maintain rotation efficiency. During the in-neutral control, a check control is performed that makes the fluid pressure relative to the input clutch fluctuate, and when determining as a result of the check control that the rotation transmission efficiency is in a predetermined low efficiency state, then reducing the fluid pressure relative to the input clutch by a set pressure, and thereafter maintaining the fluid pressure constant.Type: GrantFiled: August 28, 2009Date of Patent: July 24, 2012Assignee: Aisin AW Co., Ltd.Inventors: Gen Okumoto, Yasuo Tsukamoto, Hideki Tomida, Masahiko Nishikawa

Patent number: 8005342Abstract: A digital camera includes a signal processing circuit. The signal processing circuit makes signal processing on the camera data read from a camera data area of an SDRAM to produce YUV data for record. A thin-out circuit makes a thin-out processing on the recording YUV data to produce YUV data for display. The display YUV data and the recording YUV data thus produced are written respectively to a display data area and a recording data area of the SDRAM and thereafter processed for display on a display and record to a flash memory. The access speed to SDRAM is 48 MHz and the processing speed of the signal processing circuit and thin-out circuit is 12 MHz. Consequently, the YUV data for display and YUV data for record is written concurrently with reading out of the camera data.Type: GrantFiled: August 5, 2008Date of Patent: August 23, 2011Assignee: Sanyo Electric Co., Ltd.Inventors: Masahiko Nishikawa, Takehiko Kanda

Publication number: 20090062067Abstract: An excessive oil temperature increase prevention device for a torque converter of an automatic transmission is provided wherein, if the per-unit-time heating value of the torque converter becomes greater than or equal to an upper limit value, then the automatic transmission is downshifted and an upshift is inhibited. An expected input shaft speed and an expected input torque after the upshift are calculated. An expected speed ratio and an expected capacity coefficient are also calculated. A per-unit-time expected heating value after the upshift is calculated using the expected input shaft speed, the expected speed ratio, and the expected capacity coefficient. When the per-unit-time expected heating value becomes less than or equal to a lower limit value, the inhibition of the upshift is cancelled.Type: ApplicationFiled: August 29, 2008Publication date: March 5, 2009Applicant: AISIN AW CO., LTDInventors: Masakatsu IWASE, Shin-ichirou MURAKAMI, Hiroshi TSUTSUI, Masahiko NISHIKAWA

Patent number: 6729251Abstract: A thread taking-up tool is attached to a needle bar sticking out of a sewing machine head, and its leading end has a plurality of thread holes. The thread holes of the thread taking-up tool are arranged in the lateral direction. A thread handling body has a cam face in the vertical direction. Needle threads from a tension device to needles are controlled by the vertical motion of the thread taking-up tool and the action of the cam face of the thread handling body. When the needles ascend from the lowest position, an endless hook attached to the thread taking-up tool is engaged with the left needle thread between the cam face lower end and the thread hole of the thread taking-up tool. Each thread is handled in with the left needle thread staying at the cam face lower end, so that the needle thread loop at the remotest end is absorbed surely.Type: GrantFiled: July 31, 2002Date of Patent: May 4, 2004Assignee: Pegasus Sewing Machine Mfg.

Patent number: 6661452Abstract: A digital camera includes an SDRAM. The camera data taken is first written on a camera data area formed in the-SDRAM, and thereafter read out 8 lines a time. This 8-lines camera data is YUV-converted by a signal precessing circuit. The resulting 8-lines YUV data is stored in a work area of the SDRAM. A JPEG CODEC reads the YUV data block by block out of the work area, and compresses it. The compressed data is written block by block over the camera data area. At this time, the compressed data is written over in a manner. avoiding camera data uncompleted of compression. Such a process is repeated very 8 lines. If compressed data is obtained for all of the camera data stored within the camera data area, the compressed data is recorded at one time into a flash memory.Type: GrantFiled: February 22, 1999Date of Patent: December 9, 2003Assignee: Sanyo Electric Co., Ltd.Inventor: Masahiko Nishikawa

Patent number: 6390000Abstract: In a double chainstitch sewing machine, a movable thread guide 37 is fixed to the lower end of a needle bar 1. A fixed thread guide 41 and a thread take-up cam 39 are fixed to a jaw 43a of a sewing machine arm 43. The thread take-up cam 39 has a cam section to be engaged with needle threads 51a, 51b from the fixed thread guide 41 to the movable thread guide 37, and takes up the needle threads oscillating up and down by vertical motion of the movable thread guide 37. Thread take-up members such as movable thread guide 37, fixed thread guide 41, and thread take-up cam 39 are disposed centrally at the lower end of the needle bar near the needle and in the jaw 43a of the sewing machine arm 43. As a result, there is no member for thread take-up moving at the upper side and front side of the sewing machine arm, and dangerous positions for the operator can be decreased.Type: GrantFiled: August 6, 2001Date of Patent: May 21, 2002Assignee: Pegasus Sewing Machine Mfg.

Patent number: 5954006Abstract: The apparatus of the invention is applied to a case of folding, for example, the sleeve cloth of short-sleeved T-shirt in half while conveying. A holding device grips the leading end of the cloth conveyed on a conveying surface of narrow conveyor belts, lifts the gripped leading end of the cloth from the conveying surface, and holds it above the conveying surface temporarily. A cloth stopping device stops conveying of the front side portion of the conveyed cloth on the conveying surface at a position of an upstream side in the conveying direction from the holding device. When cloths are put on the conveying surface by overlaying mutually in part, a space is formed between the preceding cloth and succeeding cloth by the cloth stopping device, so that the leading end of the cloth is gripped and lifted by the holding device.Type: GrantFiled: September 17, 1998Date of Patent: September 21, 1999Assignee: Pegasus Sewing Machine Mfg.
