Patent number: 11926152Abstract: A printing apparatus includes a carriage mounted with a printing unit; a first motor configured to move the carriage in a predetermined direction; a second motor configured to move the carriage in the predetermined direction; and a control unit. The control unit executes a first mode in which, when causing the printing unit to perform printing under a first printing condition, the first motor is driven in a first direction and the second motor is driven in the first direction, and a second mode in which, when causing the printing unit to perform printing under a second printing condition different from the first printing condition, the first motor is driven in the first direction and the second motor is driven in the first direction while changing an output ratio between the first motor and the second motor.Type: GrantFiled: May 12, 2022Date of Patent: March 12, 2024Assignee: Canon Kabushiki KaishaInventors: Ryohei Maruyama, Daigo Kuronuma, Masakazu Nagashima, Tomohito Abe, Kenta Iimura, Hiromasa Yoneyama, Naoaki Wada, Kichinosuke Hirokawa, Akira Fujikake, Toshiaki Yamaguchi, Hideyuki Nozawa

Patent number: 6122313Abstract: A system for testing an overall system employing an integrated circuit with a modulator thereon is disclosed. The system for testing includes structure for causing the modulator to continually transmit data and structure for causing the continually transmitted data to exhibit extreme frequency deviation. In both instances the structure may be a single register. This register may also include a set of bits that may be set to select a continuous or an alternating pattern or, stated another way, a maximum or a minimum peak frequency deviation.Type: GrantFiled: June 5, 1995Date of Patent: September 19, 2000Assignees: Advanced Micro Devices, Sony CorporationInventors: Joe William Peterson, Shin Saito, Dale E. Gulick, Masaru Nonogaki, Toshiaki Iimura

Patent number: 5835476Abstract: A laser diode driving apparatus detects the laser power output of a semiconductor laser diode (13), irradiating a laser bean on a write-once or overwrite optical disk (11), by a detector (14), compares the resulting detection output signal by a comparator (17) with a laser power setting signal, modulates the resulting comparison output signal with record data by a modulating device (19), and drives the laser diode (13) by a driving device (22) with the resulting modulation output signal. By providing the modulation device (19) in the APC circuit adapted for controlling the output of the semiconductor laser diode (13), it becomes possible to automatically set the laser power necessary for recording to an optimum value, as well as to widen the temperature range and the working characteristics of the semiconductor laser diode.Type: GrantFiled: March 5, 1990Date of Patent: November 10, 1998Assignee: Sony CorporationInventors: Yoshimari Yamasaki, Yasunori Terayama, Toshiaki Iimura
