摘要:
The present invention provides a liquid application device and an inkjet recording apparatus which are capable of reducing harmful effects resulting from an increase in the number of times of using an application member (for example, a roller). An embodiment of the present invention includes: a supply port for supplying application liquid to a liquid retention space; and a collection port for collecting the application liquid from the liquid retention space, wherein the liquid is applied by a application member in a state where a negative pressure of the collection port is larger than that of the supply port. In such a configuration, the liquid supply port is arranged at a position relatively close to a transferring reference, and the liquid collection port is arranged at a position relatively far from the transferring reference.

An image forming apparatus is capable of specifying the type of an occurring abnormality to a certain extent while avoiding the increasingly complicated control that is cause when a plurality of abnormalities is detected individually according to the presence of their respective causes. A normal group data set, which is a collection of normal value combination relating to grouped information constituted by a plurality of information of differing types, is stored in RAM or ROM serving as information storage device of a control unit. At least two or more sets of grouped information, including first grouped information constituted by a plurality of different types of information, and second grouped information constituted by a plurality of information in a different combination to that of the first grouped information, are obtained from the RAM, the ROM, various sensors, and an operation display unit.

A generator apparatus can provide generated power fit for a connected battery, and even if a load voltage is not within a suitable range, when the load voltage is a certain level or more, the generator can provide power. A selector 25 selects a target voltage for controlling the output voltage of a rectifier 2. An output controller 34 controls the rectifier 2 according to the target. A load judgment section 35 judges the terminal voltage of a battery 19. When the terminal voltage is within an allowable range with respect to the target value, permission for output is given to the output controller 34. When the load voltage is not within the allowable range, an alarm is raised. Even when the alarm is raised, if a load voltage develops which is not less than a predetermined voltage lower than the allowable range, the battery 19 can be charged by forced-output.

In a print head having arrays of large nozzles and small nozzles with different ink ejection volumes that are connected to a common ink chamber, the preliminary ejection operation is performed 29,000 times first on only the large nozzles at an ejection frequency of 10 kHz to discharge viscous or mixed color ink from ink chambers. After the preliminary ejection operation of the large nozzles is finished, only the small nozzles are made to perform the preliminary ejection operation 2,000 times at an ejection frequency of 10 kHz. Reducing the number of preliminary ejections from the small nozzles in this manner can minimize the generation of stray mist. Further, by performing the preliminary ejection operation on the large nozzles first, it is possible to discharge enough viscous ink from the ink chamber.

The invention provides a gene (isolated nucleic acid molecule) encoding the cyclodextrin glucanotransferase which produces a considerable amount of γ-cyclodextrin (γ-CD) from the substrates selected from among starch and starch decomposition products such as dextrin, amylopectin and amylose; recombinant plasmids comprising this gene; transformants transformed with the recombinant plasmid; methods of manufacturing the cyclodextrin glucanotransferase by employing these transformants to act upon the substrates selected from among starch and decomposition products thereof and causing the production of γ-CD as a main product; and methods of manufacturing γ-CD and CD-comprising compositions having a desired CD balance (α-, β- and γ-CD balance) employing this recombinant cyclodextrin glucanotransferase.

An electric vehicle driven by a pair of left and right electric motors is provided. The vehicle includes a controller for controlling the start of the vehicle. The controller performs such control as avoiding brake drag caused by the operation of the electric motors before the elimination of the braking of a pair of left and right parking electromagnetic brakes.
摘要:
The absence or shortage of a heat transfer medium can be detected without any time lag. While the medium is circulated through a water jacket and an exhaust gas heat exchanger which receives heat from the exhaust gas, heat generated by the engine can be recovered. A first sensor is provided at a waste heat recovering location in a circulation path of the medium. A second sensor is provided at a downstream side of sensor. When the medium is absent, a difference in measured temperature develops between sensor and sensor. A heat transfer medium shortage signal is outputted when the difference in the measured temperature between the first sensor and the second sensor exceeds a predetermined reference level.

A high-quality image is printed with reduced bleeding in colors that may appear at a boundary between a black image and a color image. A head for ejecting black ink and a head for ejecting color ink perform three times of scanning while feeding is carried out therebetween for moving the printing medium by four pitches of ejection openings arranged on the heads, different ejection openings are caused to correspond to a scanning area, which corresponds to the four pitches, and multi-pass printing is performed to complete printing on the area. The black head completes printing of the black image, and then, the color head completes printing of the color image adjacent to the black image. The arrangement of ejection openings is determined so that between last scanning for completing printing of the black image and the first scanning for printing of the color image, scanning with no performing printing exists.
摘要:
A printing apparatus and a printing control method are disclosed, which can ensure a sufficient acceleration area for stable movement of a carriage and realize the downsizing. According to the printing apparatus, an inkjet printhead is used, on which a plurality of nozzle arrays each having a plurality of nozzles for discharging ink are arranged in a direction different from the array direction of the nozzles. The apparatus performs printing operation on a printing medium by discharging ink while reciprocally moving the carriage, on which the above inkjet printhead is mounted, in a direction in which the plurality of nozzle arrays are arranged. When preliminary discharge is performed from the inkjet printhead to an ink receptor arranged on at least one end of a reciprocal movement area of the inkjet printhead, the carriage is stopped. The scanning of the carriage is controlled so that the carriage accelerates from zero speed to a predetermined speed after the preliminary discharge is completed, and moves at the predetermined speed. On the other hand, the movement of the carriage and preliminary discharge are so controlled as to sequentially perform preliminary discharge with regard to the plurality of nozzle arrays from one nozzle array arranged outside the reciprocal movement area to another nozzle array arranged inside the area.
