Publication number: 20040029526Abstract: When an image transmitter and a mobile phone are connected, it is determined whether or not a connection (communication) is established between a communication section and the mobile phone. If it is determined that the connection is established, the image transmitter transmits to the mobile phone a signal to request the mobile phone to obtain identification information given to the mobile phone. The image transmitter determines whether or not pre-stored identification information in the storage unit and the obtained identification information match. If it is determined that the identification information matches, the image transmitter reads image data stored in the storage unit and transmits the image data to the mobile phone.Type: ApplicationFiled: July 31, 2003Publication date: February 12, 2004Applicant: FUJITSU LIMITEDInventors: Atsushi Miki, Shuji Kimura, Keiji Fujiwara, Satoshi Fukui, Kiyoshi Chinzei, Mieko Nakano

Publication number: 20040029552Abstract: It is determined whether or not a connection is established between the communication section of an image transmitter and a mobile phone. If it is determined that the connection is established, a request command is transmitted to the mobile phone to obtain the model information of the mobile phone. When the mobile phone receives the request command, it reads the model information from an internal memory, and transmits the model information to the image transmitter. When the image transmitter obtains the model information in response to the request for the model information, it reads conversion information corresponding to the obtained model information with reference to a conversion table. Then, the image transmitter converts the image data stored in a storage unit, based on the read conversion information, and transmits the converted image data to the mobile phone of the image transmitter through the communication section.Type: ApplicationFiled: July 31, 2003Publication date: February 12, 2004Applicant: FUJITSU LIMITEDInventors: Atsushi Miki, Shuji Kimura, Keiji Fujiwara, Satoshi Fukui, Kiyoshi Chinzei, Mieko Nakano

Patent number: 5353882Abstract: A screwing apparatus includes a multi-phase motor and a control device. The motor rotates a bit, installed on the motor, for rotating a screw. The control device controls a rotational speed of the motor by calculating a rotational speed of the bit based on commutation signals outputted from sensors installed on the motor, and controls a torque value of the bit by outputting instructions to the motor so that the bit is rotated at a predetermined torque value.Type: GrantFiled: December 17, 1993Date of Patent: October 11, 1994Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hiroyuki Inoue, Keiji Fujiwara, Tomomi Ogawa, Masumi Tezuka
