Patent number: 8357013Abstract: The present invention involves connectors for reducing Far-End Crosstalk (FEXT) through the use of novel polarity swapping to negate the cumulative effect of FEXT. Skew adjustment is used to improve the FEXT cancellation from polarity swapping. The polarity reversal location or locations among FEXT sources are optimized to achieve maximum FEXT cancellation. The novelty polarity swapping technique can be applied to a wide variety of connectors, such as mezzanine connectors, backplane connectors, and any other connectors that can benefit from FEXT reduction.Type: GrantFiled: November 5, 2009Date of Patent: January 22, 2013Assignee: Hirose Electric Co., Ltd.Inventors: Tatsuya Arai, Ching-Chao Huang, Clement Kam Lam Luk, Jeremy Buan, Tsutomu Matsuo, Toshiyuki Takada, Masakazu Nagata

Patent number: 8282399Abstract: An electrical connector includes a housing having an opening portion in an upper surface thereof including a width edge in a short side direction and a side edge in a long side direction; a terminal disposed in the housing; and a suction member detachably attached to the housing. The suction member includes a plate portion for covering the housing and an attachment portion for attaching to the housing at a middle portion of the side edge. The plate portion includes an attachment region between both end portions of the attachment portion in the long side direction and a non-attachment region outside the attachment region extending to a distal end portion of the plate portion in the long side direction. The non-attachment region includes a deformable portion with a free end portion to be deformable.Type: GrantFiled: September 8, 2010Date of Patent: October 9, 2012Assignee: Hirose Electric Co., Ltd.Inventors: Takeshi Saito, Masakazu Ezaki, Toshiyuki Takada

Patent number: 8156399Abstract: A low density parity check codes decoder decodes an LDPC code with an arbitrary coding rate by the same configuration. The low density parity check codes decoder enables decoding of an LDPC code constituted by a base matrix of Mbmax rows and Nbmax columns and a permutation matrix as an element of the base matrix. It stores therein MbmaxĂ—Nbmax validity/invalidity flags, shift amounts of valid permutation matrices, a permutation matrix size in a processing target code, and the number of rows of a base matrix in the processing target code, determined depending on a check matrix for the processing target LDPC code, and generates column addresses and a row address to be given to column processing calculation sections and a row processing calculation section that perform calculation in accordance with a BP algorithm by utilizing the stored information, so that it can process an LDPC code for a smaller base matrix than the aforementioned base matrix as well.Type: GrantFiled: March 7, 2011Date of Patent: April 10, 2012Assignee: Mobile Techno Corp.Inventors: Atsuhiko Sugitani, Toshiyuki Takada

Patent number: 7604483Abstract: An electrical connector assembly has a fixed connector, a middle connector, and a plug connector. The fixed connector is attached to a circuit member of an electrical device. The middle connector is connected and pulled out to and from the fixed connector in a direction same as that of the plug connector being connected and pulled out to and from the middle connector. Each of the fixed connector, the middle connector, and the plug connector is provided with engagement portions at both end portions thereof in a direction parallel to a straight line extending in a different direction from an insertion and pull-out direction. With the engagement portions, it is possible to prevent the fixed connector from coming off from the middle connector when the plug connector is pulled out.Type: GrantFiled: December 20, 2007Date of Patent: October 20, 2009Assignee: Hirose Electric Co., Ltd.Inventors: Toshiyuki Takada, Tadashi Ohshida

Patent number: 7462040Abstract: An electrical connector for a circuit board is provided with a relay member connection body and a relay member receiving body. The relay member connection body is provided with terminals and a terminal holding body to hold the terminals. The relay member receiving body is fitted into the relay member connection body and receives a relay member that is to be connected with the terminals. The relay member receiving body is provided with receiving grooves extending in the assemble direction to receive the relay member. One end side of the terminal is held, and a contact portion elastically bendable inward of the receiving groove is provided in the other end side of the terminal. A distal portion of the terminal on the other end side abuts against the relay member receiving body, so that the terminals receive pre-compression in an elastically bending direction of the contact portion.Type: GrantFiled: November 15, 2007Date of Patent: December 9, 2008Assignee: Hirose Electric Co., Ltd.Inventor: Toshiyuki Takada
