    摘要: In a data packet transmission method and an apparatus for realizing the method, data packet transmission/reception is performed between communication apparatuses each having a CPU for controlling an entire operation of the apparatus. An operating efficiency of the CPU of the communication apparatus on a reception side is detected when a data packet transmission/reception request is generated. An optimum data packet length for reception of a data packet is determined in correspondence with the detected operating efficiency, and the communication apparatus on a transmission side is informed of the optimum data packet length. The data packet to be transmitted is assembled to have the optimum data packet length, and the data packet is transmitted.

    摘要: For use in combination with a data processing apparatus (50) which is provided with a card connecting portion for connecting a card-shaped device therewith, a portable telephone apparatus (20) has a card-shaped portion which can be connected to the card connecting portion instead of the card-shaped device. The data processing apparatus is for processing a datum. When the card-shaped portion is connected to the card connecting portion, the datum can be transferred between the data processing apparatus and the card-shaped portion. Therefore, the portable telephone apparatus enables the data processing apparatus to carry out communication relating to the datum.

    摘要: An optical head has a first light source for emitting a first light beam having a first wavelength, a second light source for emitting a second light beam having a second wavelength larger than the first wavelength, and an optical system for guiding the first and second light beams to an optical disc and guiding light beams reflected by the optical disc to an optical detector. The optical system, includes an objective lens, a beam splitter for reflecting the first light beam and the S-polarized component of the second light beam and transmitting the P-polarized component of the second light beam, and a quarter wavelength plate. When a high density medium is set against the optical head, recording is performed by the second light beam and reproduction is performed by the first light beam. When a low density medium is set against the optical head, recording and reproduction are carried out by the second light beam. A single optical head provides read/write compatibility with optical discs of different densities, and recording and reproduction can be made on a high density optical disc.

    摘要: The present invention relates to a plasma etching method in which a special area for detecting an end point needs not to be set and an equipment therefor. At an etching step of forming SF6 gas into plasma to etch an etching ground on a Si film, the step is configured by two steps of: a large-amount supply step of supplying a large amount of SF6 gas; and a small-amount supply step of supplying a small amount of SF6 gas. An end-point detecting processor 34 measures an emission intensity of Si or SiFx in the plasma at the small-amount supply step, and determines that an etching end point is reached when the measured emission intensity becomes equal to or less than a previously set reference value.

    摘要: According to one embodiment, an automotive display apparatus includes an image projection unit and a control unit. The image projection unit is configured to project a light flux including an image by using a reflecting unit to reflect the light flux. The control unit is configured to control an operation of the image projection unit so that the image projection unit moves a projection region of the light flux by an amount substantially proportional to (Vc)2×δ from a predetermined initial position in a horizontal direction orthogonal to an optical axis of the light flux projected toward the predetermined initial position, where the Vc is a velocity of a vehicle and the δ is a steering angle of the vehicle.
