摘要:
This invention discloses a wholly wrapped railroad crosstie. It is composed of an inner core and a shell that is made of deformable composite materials. The shell is molten and united together with the inner core as a whole when it is formed. The shell covers the inner core wholly. There's no seam on the crosstie at all. So it successfully avoids the separation and friction of the crosstie. It greatly increases the reliability and service life of the crosstie. And it reduces the cost of maintenance.

An image data buffer apparatus includes a memory, and a FIFO control unit configured to cause the memory to operate as a FIFO and having a write pointer indicative of a write position of the memory and a read pointer indicative of a read position of the memory, wherein the FIFO control unit is configured to store image data as a plurality of blocks in the memory at respective positions successively indicated by the write pointer as the image data are supplied as the blocks contained in an image, to read one of the blocks from the memory at a position indicated by the read pointer, to read, from the memory, partial data that is part of at least one block adjacent to the one of the blocks, and to consolidate the one of the blocks and the partial data for transmission as one consolidated block.
摘要:
A plasma display panel of a surface discharge type is disclosed, which can positively generate the discharge for display while suppressing the power consumption even when the number of the electrodes is increased for attaining the high definition. A plurality of display electrode pairs (x,y) are arranged in proximity with each other inside of a pair of substrates opposed to each other with a discharge gap formed therebetween. Each display electrode (x;y) includes a main pattern (3) extending in one direction, independent discharge patterns (2b) each formed for each luminous area corresponding to a display cell, and a plurality of auxiliary patterns (4) for electrically connecting the main pattern (3) and the discharge patterns (2b) to each other. The auxiliary patterns (4) are higher in conductivity than the discharge patterns (2b) in one embodiment, and are integral with the discharge patterns (2b) in another embodiment.

The present invention provides a wireless terminal apparatus (10), including a reception unit (11, 12) for receiving a multi-carrier signal generated by applying an N-point (where N is a natural number) inverse fast Fourier transform (IFFT) to a plurality of sub-carriers to which transmission information for a plurality of wireless terminal apparatuses is allocated; a fast Fourier transform unit (15) for extracting a plurality of the sub-carriers from the multi-carrier signal; a thin-out unit (14), being placed at the front stage of the fast Fourier transform unit, capable of changing, from the N points, a sampling number of the multi-carrier signals which are digitalized; and a judgment unit (17) for discerning, based on sub-carrier allocation information accompanying the multi-carrier signal, whether or not the sub-carrier of another wireless terminal apparatus overlaps with that of the wireless terminal apparatus itself in the case of changing the sampling number from the N points, and determining a sampling number for the thin-out unit.

A cache memory (50) built in a processor (10) comprising a plurality of independent memory blocks (53b), pass/fail information memory unit (56a) memorizing a presence/absence of a failure occurring in each of the memory blocks (53b), and a screening control function (54) substituting a sound memory block for a failedmemory block based on a memory content in the pass/fail information memory unit (56a).
摘要:
An electronic apparatus which is capable of detecting faults that cannot be detected with a fixed signal pattern and which also permits fault detection to be performed even during the operation thereof. Signal processor circuits perform identical signal processing, and a signal router causes the signal being input to an operating signal processor circuit which is performing the signal processing among the signal processor circuits, to be input to an idle signal processor circuit which is not performing the signal processing. A fault detector compares an operating output signal output from the operating signal processor circuit with an idle output signal output from the idle signal processor circuit to detect a fault.
摘要:
A method and system for creating a transition between a first scene and a second scene on a computer system display, simulating motion. The method includes determining a transformation that maps the first scene into the second scene. Motion between the scenes is simulated by displaying transitional images that include a transitional scene based on a transitional object in the first scene and in the second scene. The rendering of the transitional object evolves according to specified transitional parameters as the transitional images are displayed. A viewer receives a sense of the connectedness of the scenes from the transitional images. Virtual tours of broad areas, such as cityscapes, can be created using inter-scene transitions among a complex network of pairs of scenes.
