A liquid crystal display control apparatus includes a display on/off data generation circuit for generating plural display on/off data per pixel corresponding to M (M>N, M and N being integers) frame periods of a video output signal in N frame periods of a video input signal on a unit pixel basis in response to gray-scale data of pixel units included in the video input signal, a write control circuit for writing display on/off data per pixel corresponding to M frames of the video output signal generated by the display on/off data generation circuit into a frame memory during N frame periods of the video input signal, and a read control circuit for sequentially reading out, from the frame memory, display on/off data corresponding to M frames of the video output signal written in the frame memory in synchronism with one display scan period of the video output signal, thereby the data written in the frame memory is not gray-scale data but display on/off data of one bit, therefore, a data bus width at a time of accessing the frame memory can be reduced.

A display apparatus includes a display having a plurality of pixels, and a controller which selects a pattern corresponding to a gradation of gradation data. On-state pixels are added to a pattern corresponding to one gradation of the gradation data to obtain a pattern corresponding to another gradation of the gradation data higher than the one gradation of the gradation data while maintaining unchanged an arrangement of on-state pixels in the pattern corresponding to the one gradation of the gradation data.

A liquid crystal controller for controlling display of a liquid crystal display device of passive matrix type includes gray scale processing being performed on input data before being written in a frame memory for frame frequency conversion and gray scale processing being performed after the frequency conversion and reading of the data from the frame memory so that an amount of information of display data written in the frame memory can be reduced. Further, since the gray scale display pattern is switched by the same switching frequency as the converted frame frequency, pattern movement and flicker of the gray scale display portions can be reduced.

A patterned magnetic recording medium, accessible by a magnetic recording head, including a plurality of tracks, a width direction of each track and that of the magnetic recording head being of a skew angle. The patterned magnetic recording medium includes a plurality of magnetic dots, each corresponding to a recording bit, formed on a non-magnetic material. The plurality of magnetic dots are arranged in a plurality of arrays, each array corresponding to one of the tracks. Every N adjacent magnetic dots of the array define a polygon, one side thereof being parallel to the corresponding track, and another side thereof being parallel to a direction corresponding to the skew angle of the corresponding track.

A connector for an IC card is provided which has a reduced height and in which self-correction is possible. The connector includes a plurality of cantilever contacts electrically connected to an IC card, each including a stationary arm and a resilient arm having a tip formed with a contact point. The connector also includes a housing holding the contacts and integrally formed with the stationary arm so that the contact point projects from one surface of the housing. The resilient arms are bendably arranged in parallel and are slidable with respect to the IC card inserted from any one of the first and second insertion directions.

Provided is an optical element in which a groove for a sample to make contact can be formed without machining or etching a material for an optical element, and in which the scattering of a light at the groove does not decrease the precision in an optical measurement. The optical element is formed with a light-emitting prism including a light-output face from which a light to be emitted to a sample is outputted, a light-receiving prism including a light-receiving face which receives the light returned from the sample, and a light intensity-reducing part provided between the light-emitting prism and the light-receiving prism. The light-emitting prism and the light-receiving prism are combined to form a recessed part for the sample to make contact, so that the light outputted from the light-output face travels straight in the sample in contact with the recessed part and enters the light-receiving face.

In a connector housing (2), resinous guide walls (4,5) that slide and guide a card holder (3) are erected on both sides in a width direction (B) perpendicular to a direction (A) in which the card holder (3) holding a memory card (C) is inserted. The metallic guide walls (4,5) are provided with metallic reinforcement tabs (6,7) molded integrally with the guide walls (4,5) simultaneously. The metallic reinforcement tabs (6,7) can give rigidity and elasticity to the resinous guide walls (4,5). Therefore, after the card holder (3) is inserted, the card holder (3) inserted therein can be stably held so as not to easily slip off.
