Publication number: 20170282890Abstract: A vehicle control apparatus includes an electronic control unit. The electronic control unit is configured to perform feedback control of a motor such that a torque is output for stopping a crankshaft at a target angle. A first angle is used as the target angle during a first period from start of the feedback control to first detection of rotation of the crankshaft in a negative rotational direction for returning the crank angle. A second angle is used as the target angle during a second period from the lapse of the first period to detection of a changeover in a rotational direction of the crankshaft from the negative to a positive rotational direction. The electronic control unit is configured to return the target angle to the first angle at a first timing after the lapse of the second period.Type: ApplicationFiled: March 31, 2017Publication date: October 5, 2017Inventors: Akihiro FUJIMOTO, Wan Leng ANG, Yu MIYAHARA, Yuji IWASE

Patent number: 8636915Abstract: To provide a liquid processing apparatus capable of processing substrates with a high throughput with the lesser number of nozzles for chemical-liquid, when the substrates that are horizontally held in cup bodies are liquid-processed by supplying a chemical liquid to the substrates. Taking a developing process as an example of a liquid process, two-types of developing nozzles are prepared for two types of developing methods. The developing nozzle, which is used in the method in which the nozzle is engaged with the process for a longer period of time, is individually disposed on each of a first processing module 1 and a second processing module 2. On the other hand, the developing nozzle, which is used in the method in which the nozzle is engaged with the process for a shorter period of time, is used in common in the first liquid processing module 1 and the second liquid processing module 2. The common developing nozzle is configured to wait on an intermediate position between the modules 1 and 2.Type: GrantFiled: July 12, 2011Date of Patent: January 28, 2014Assignee: Tokyo Electron LimitedInventors: Yasushi Takiguchi, Taro Yamamoto, Tsutomu Yamahata, Akihiro Fujimoto, Kouji Fujimura

Publication number: 20130300011Abstract: Since a space between one of a plurality of recessed portions 42c formed in a sub-master substrate 42 and a first molding surface 31 of a master die 30 is filled with a first resin material 41b, the thickness of a sub-sub-master resin layer 51 formed on the entire sub-master substrate 42 can be made relatively small while ensuring the thickness of the first resin material 41b which faces the first molding surface 31. Therefore, warpage of the sub-master substrate 42 caused by the sub-sub-master resin layer 51 can be prevented while easily increasing the positioning accuracy of the master die 30. By providing an annular step 32 in the periphery of the first molding surface 31, a residual film portion 44 which is an outer edge portion of the sub-sub-master resin layer 51 can be formed between the step 32 and the periphery of a recessed portion 42c.Type: ApplicationFiled: January 23, 2012Publication date: November 14, 2013Inventor: Akihiro Fujimoto
