摘要:
A computer system is connected to a printer via a parallel interface, for point-of-sale (POS) applications employing one or more different paper sources, such as, continuous tape, document insertion, and sheet validation. A detector is associated with each paper source to sense a paper empty or out condition. The printer has an addressable latch that enables a choice of one or more of these detectors for connection through to a single status line within the parallel printer interface. The computer CPU can access the addressable latch prior to any printing so that the presence of an appropriate type of paper in its appropriate print position in the printer can be checked or tested utilizing an industry standard parallel printer interface, such as, the widely employed Centronics interface.
摘要:
A printer control device is employed with host computer controlled printers, typically of the point-of-sale (POS) type, which are capable of printing on several different types of recording paper. Several detectors are used on the printer to sense out-of-paper conditions with at least one detector being associated with each paper source used, and a detector selection device is used to determine which detector outputs are to be connected to the host computer through a communications interface. Detector output values can be stored and logically combined to allow transfer over a single communications line. Specific detector outputs can be enabled or selected for transfer to the host or for use in termination of printing operations. A paper type selector is used for setting line spacing or advancement amounts which are stored by the printer controller for later retrieval. Typically each advancement value relative to one type of paper is stored separately in a memory location or element. The type of recording paper and line advancement value for that paper are each selected by a printer control command, which is interpreted and acted upon by the printer controller. The printer controller responds to data printing commands and activates paper transfer mechanisms within the printer to achieve the established line advancement values during printing operations.

According to one embodiment, a method is disclosed for manufacturing a semiconductor light emitting device. The method can include forming a nitride semiconductor layer including a light emitting layer on a first substrate having an unevenness, bonding the nitride layer to a second substrate, and separating the first substrate from the nitride layer by irradiating the nitride layer with light. The forming the nitride layer includes leaving a cavity in a space inside a depression of the unevenness while forming a thin film on the depression. The film includes a same material as part of the nitride layer. The separating includes causing the film to absorb part of the light so that intensity of the light applied to a portion of the nitride layer facing the depression is made lower than intensity of the light applied to a portion facing a protrusion of the unevenness.

A fixing device includes a fixing rotary body, an opposed member opposing the fixing rotary body to form a nipping portion, and a heater to heat the fixing rotary body. The heater includes heat generators arranged in a width direction of a recording medium and separately supplied with power. When an unfixed image on the medium has an image area and a non-image area, power supplied to each of the heat generators is controlled so that, of the heat generators, a first heat generator corresponding to the image area becomes a higher temperature and second heat generators corresponding to the non-image area becomes a lower temperature. When the second heat generators are adjacent to each other, power supplied to one of the second heat generators closer to the image area is set to be greater than power supplied to another of the second heat generators farther from the image area.

A high pressure fuel pipe construction for an internal combustion engine, such as a direct injection engine. A conduit for the fuel is open at each end and a ball having a throughbore is slidably positioned over one end of the conduit. A reinforcing sleeve is positioned inside the end of the conduit so that the sleeve extends entirely through the ball. The sleeve, ball and the end of the conduit are then brazed together to attach the ball and conduit together. A double chamfer is provided at one end of the ball throughbore to facilitate inspection of the brazing quality. Additionally, a loop is formed in the conduit and a dampener is attached to the loop.

The present embodiments provide an acceleration sensor, which enables highly accurate detection and has an extremely compact size. The acceleration sensor of the present embodiments is provided with a substrate, a anchor portion formed on the substrate, a support beam, which has one end connected to the anchor portion and extends across a space from the substrate, and a proof mass which is connected to the other end of the support beam and held across a space from the substrate. The acceleration sensor is further provided with first and second piezoelectric bending resonators, a comparison unit, and a calculation unit. The first and second piezoelectric bending resonators have one end connected to the anchor portion and the other end connected to the proof mass or the support beam and have a stack of a first electrode, a first piezoelectric film, and a second electrode. The first and second piezoelectric bending resonators extend on the both sides of the support beam and perform bending resonance motion in a direction perpendicular to the piezoelectric film. The comparison unit measures a difference of a resonance frequency between the first and second piezoelectric bending resonators. The calculation unit calculates an acceleration in a direction perpendicular to the extending direction of the support beam in the substrate surface from the difference of the resonance frequency.
