摘要:
A suction apparatus includes a volume-variable chamber having an inlet and an outlet which is formed by a plurality of enclosing parts including an elastic part. A slider applies a force to the volume-variable chamber to decrease the volume thereof and a valve applies a force to increase the volume thereof. When the slider decreases the volume, the valve opens the outlet to drain ink and air from the volume-variable chamber. When the valve increases the volume, the valve closes the outlet to produce a suction force.

A mechanism by which interrupt frequency mitigation is combined with transmit raw cell status report frequency mitigation is presented. A tx raw cell status report is allowed to occur for only every N raw cell tx slots consumed. When the rate of interrupt requests is mitigated in accordance with holdoff parameters including a holdoff event count corresponding to X interrupt events and a holdoff time interval, and the raw cell status report counts as an interrupt event, an interrupt request is generated for an enabled interrupt if N*X events has occurred or the holdoff time interval has elapsed.

摘要:
In a device used to inspect substrates visually, an imaging region and a magnification are specified ahead of time for every component and stored as library data in a memory. The memory also contains CAD data, which include the class of each component on the substrate and its location. During initialization, a control unit links the location data for a component extracted from the CAD data to corresponding library data and specifies a field of view and a magnification for every component on the substrate. Using this data, the control unit creates on the substrate a number of viewing zones to be inspected at various magnifications and stores the data specifying these zones in the memory. When a substrate is to be inspected, the control unit uses the data specifying these zones to control the position and magnification of an imaging unit to collect image data from each zone successively and display them on a monitor.

摘要:
A communication control system for providing and registering a plurality of virtual circuits and sequentially transferring cells via the virtual circuits in response to request for transferring cells in an synchronous transfer mode is described. The communications control system comprises a device for determining whether or not it is permitted to transfer a cell via each virtual circuit having been registered in order to control the rate of transferring cells via the virtual circuit, and a device for erasing the registration of each virtual circuit if no cell is transferred via the virtual circuit for a predetermined time period after latest transmission on the basis of information for controlling the rate of transferring cells via the virtual circuit. In this configuration, erroneous operation is prevented which originates from overflow occurring in a counter for counting the present time.

The present invention is directed to a method and an apparatus for producing thin-film EL devices with short annealing treatment times and excellent productivity.A substrate to be subjected to annealing treatment is mounted on the surface of a stage. The substrate to be treated is constructed by forming lower electrodes, a lower insulating layer, an EL layer and an upper insulating layer in that order on a translucent substrate. Light-irradiating means is provided above and opposite the surface of the stage. The light-irradiating means includes a plurality of light sources and a reflecting panel, and the light sources are situated along each of a plurality of concavities provided in the reflecting panel. Light from the light sources irradiates roughly the entire surface of the substrate to be treated. The light from the light sources is selected so as to include the absorption wavelength band of the electrode material of the lower electrodes on the substrate. When a prescribed temperature is reached, the light irradiation is terminated to allow cooling.
