Patent number: 6918645Abstract: In a thermal transfer printer driven by a battery power source, to perform a print operation, the remaining capacity level of the battery power source (remaining battery capacity level) is detected by a voltage detector immediately before paper is fed out of a paper cassette and transferred for printing. The detected remaining battery capacity level is compared with a criterion level, which is a print-driving power required for one sheet of paper. If the remaining battery capacity level is lower than the criterion level, control is performed to stop the commencement of a print-driving operation. Thereby, the battery-driven printer averts printing from being terminated partway because of depletion in the battery power, and furthermore, enables printed sheets of the paper to utmost be increased.Type: GrantFiled: August 9, 2001Date of Patent: July 19, 2005Assignee: Olympus CorporationInventor: Yasuo Takahashi

Patent number: 6884281Abstract: First, the overall quantity of bubbles in a coating liquid is reduced in advance by vacuum deaeration performed in conjunction with preparation of the coating liquid in a stirring tank in a first step, then bubbles of relatively large sizes, of bubbles that have not been removed in the first step are removed by a tank type deaeration device with ultrasonic waves in a floatation tank in a second step, and finally bubbles of very small to small sizes that are difficult to remove in the first and second steps are dissolved in the liquid under pressure with ultrasonic waves and thereby removed in a pipeline in a third step. According to this, bubbles in the coating liquid can reliably be removed irrespective of the nature of the coating liquid, a large amount of coating liquid can be treated, and the possibility that the quality of the deaerated coating liquid is adversely affected is eliminated.Type: GrantFiled: March 5, 2003Date of Patent: April 26, 2005Assignee: Fuji Photo Film Co., Ltd.Inventor: Yasuo Takahashi

Patent number: 6624834Abstract: If printing is commenced while a relay is supplying power supply voltage from a battery to a power supply controller, a control circuit outputs a power supply switching prohibition signal to a permission/prohibition circuit. Even if an AC adapter is connected during printing, the relay will not be switched by an ON signal from an input voltage determination circuit. Once the printing is completed, the power supply switching prohibition signal is stopped, and a switch is made to power supply input from the AC adapter. As a result, even if an AC power supply is connected during printing, this will not cause the printing to take a longer time, and will prevent a decrease in printing quality.Type: GrantFiled: August 7, 2001Date of Patent: September 23, 2003Assignee: Olympus Optical Co., Ltd.Inventor: Yasuo Takahashi
