The second branching portion includes a liquid outflow pipe and a gas outflow pipe. The liquid outflow pipe defines one outlet for the refrigerant and is located below the gas outflow pipe. The gas outflow pipe defines another outlet for the refrigerant and is located above the liquid outflow pipe. The one outlet of the second branching portion communicates with the third branching portion. The other outlet of the second branching portion communicates with the fourth branching portion.Type: ApplicationFiled: March 30, 2021Publication date: April 25, 2024Applicant: Mitsubishi Electric CorporationInventors: Kosuke MIYAWAKI, Yuki MIZUNO, Soshi IKEDA, Jun NISHIO, Yuji MOTOMURA, Koji FURUYA, Hiroki WASHIYAMA

Publication number: 20240077238Abstract: A refrigeration cycle device with a main circuit, a bypass circuit and a supercooling heat exchanger further includes: a controller to control an opening degree of the bypass expansion valve; a first sensor to detect a temperature at the refrigerant inflow side of the evaporator; and a second sensor to detect a pressure of the non-azeotropic mixed refrigerant flowing from the evaporator, wherein the controller controls the opening degree of the bypass expansion valve using temperatures of the evaporator, that is, the temperature at the refrigerant inflow side and a saturated gas temperature of the non-azeotropic mixed refrigerant calculated from the pressure so as to adjust a flow rate of the non-azeotropic mixed refrigerant flowing into the evaporator, to eliminate the temperature difference in the evaporator for suppressing uneven frost formation on the evaporator, and thus to prevent heat exchange performance from degrading.Type: ApplicationFiled: February 2, 2021Publication date: March 7, 2024Applicant: Mitsubishi Electric CorporationInventors: Yuki MIZUNO, Soshi IKEDA, Kosuke MIYAWAKI, Jun NISHIO, Yuji MOTOMURA, Hiroki WASHIYAMA

Patent number: 8345160Abstract: A synchronous signal conversion circuit converts a first synchronous signal, which is transmitted with a data signal, to a second synchronous signal conforming to a predetermined standard. In the synchronous signal conversion circuit, a transition detection circuit detects transition of the first synchronous signal. A synchronous signal generation circuit generates a second synchronous signal in response to a detection result by the transition detection circuit. An output timing control circuit delays the second synchronous signal generated by the synchronous signal generation circuit so that the second synchronous signal synchronizes with the data signal.Type: GrantFiled: August 25, 2008Date of Patent: January 1, 2013Assignee: Panasonic CorporationInventor: Yuki Nishio

Patent number: 7689164Abstract: The present invention relates to a wireless LAN (Local Area Network) communication system. Upon a timer unit 108 clocking a predetermined time T after an access point 100 has transmitted a beacon signal 200, a transmission frame control unit 105 generates a CTS frame 301, and transmits an error frame 401 via a transmission frame generation unit 106, a wireless transmission unit 107 and an antenna 109. Accordingly, upon receiving the CTS frame 301, a communication terminal 20 ceases transmitting data for a NAV (Network Allocation Vector, transmission prohibition interval) period in accordance with IEEE 802.11 standard.Type: GrantFiled: March 1, 2007Date of Patent: March 30, 2010Assignee: Panasonic CorporationInventors: Yuki Nishio, Masataka Irie

Patent number: 5731122Abstract: An image forming method and image forming apparatus for charging a photosensitive member, exposing the charged photosensitive member thereby forming an electrostatic latent image, carrying toner with a toner carrying member to bring the toner into contact with the photosensitive member surface, thereby developing the electrostatic latent image and forming a toner image upon the photosensitive member, transferring the toner image that is on the photosensitive member to transfer material such as paper, and conducting a simultaneous developing-cleaning process which recovers residual toner remaining on the photosensitive member following the transfer process, so that toner consumption is greatly reduced and high image quality is maintained at the same time. The angle of contact of the photosensitive member surface to water is 85.degree.Type: GrantFiled: November 8, 1995Date of Patent: March 24, 1998Assignee: Canon Kabushiki KaishaInventors: Satoshi Yoshida, Motoo Urawa, Shuichi Aita, Tsutomu Kukimoto, Yoshifumi Hano, Yuki Nishio

Patent number: 5576810Abstract: An electrophotographic image forming method including a toner image transfer step and eliminating an independent step for cleaning transfer residual toner is operated without causing ghost images and with good gradation and dot reproducibilities. In the method, the photosensitive member is exposed at an exposure intensity which is at least a minimum exposure intensity and below a maximum exposure intensity. The minimum exposure intensity is determined on a surface potential-exposure intensity characteristic curve of the photosensitive member by determining a first slope S1 of a straight line connecting a point giving a dark part potential Vd and a point giving a value of (Vd+ a residual potential Vr)/2, determining a contact point between a tangent line having a slope of S1/20 and the surface potential-exposure intensity characteristic curve and determining the minimum exposure intensity as an exposure intensity at the contact point.Type: GrantFiled: September 29, 1995Date of Patent: November 19, 1996Assignee: Canon Kabushiki KaishaInventors: Shuichi Aita, Toshiyuki Yoshihara, Tsutomu Kukimoto, Satoshi Yoshida, Yoshifumi Hano, Yuki Nishio
