摘要:
A linear actuator can obtain a roughly fixed load within a stroke range. The linear actuator comprises a fixed element, comprising a yoke and a magnet which is magnetized in the radial direction, and a moving element, comprising an electromagnetic coil and a bobbin which surrounds the magnet. A spring is provided for applying a force acting in opposition to the thrust direction acting on the moving element. A constant load stroke area is provided so that the characteristics of the opposite force of this spring balance the characteristics of the thrust force acting on the moving element. The constant load stroke area is an area where one end of the coil in the stroke direction is located in an outside position from one end of the magnet in the stroke direction, and the other end of the coil in the stroke direction is located in an inside position from both ends of the magnet in the stroke direction.

A device to perform tone generation while efficiently using a broad bit width bus and essentially eliminating the delay from the request for tone expression until its expression. An arithmetic processing device that generates tones reads the data all at once from a memory in which tone data is stored. This is set so that the delay time from when there is a request for tone generation until the tone is actually generated and expressed is negligible.

摘要:
A three-dimensional image rendering portion, based on image data, performs geometric transformation, projection transformation, etc. and further applies texture data from the texture memory onto polygons, to thereby generate graphic data of a 3-D image. This graphic data is used as pixel data for a frame of image and written into the frame memory. A 3-D texture modeling value generating circuit performs arithmetic operations on 3-D texture modeling values of asperities of the textures, using coordinate data given from the 3-D image rendering portion, bump data stored in the texture memory and parameters stored in the register. These 3-D texture modeling values are provided to 3-D texture modeling circuit where, based on these values, the data from the frame memory is formed into a 3-dimensional form, which in turn is displayed on the display unit.
摘要:
A vector normalizing apparatus which normalizes an input vector or weight vectors by L.sub.2 -norm and adds norm information to the vector before it is normalized. Vector data from an input vector acquiring device (1) is displayed on an input vector display device (2) and transmitted through a vector transmitting device (3) to a normalized vector output device (4). During the transmission of the vector data, L.sub.2 -norm of the vector data is calculated by an L.sub.2 -norm calculating device (5) including a vector component squaring device (7) for squaring each of the components of the displayed vector, a summation device (8) for calculating a total sum of the squared components, and a square-root calculating device (9) for calculating L.sub.2 -norm by obtaining a square root of the result of the summation. The input vector is normalized by a vector component adjusting device (6) using the calculated value of L.sub.2 -norm. Thus, the input vector normalized by the L.sub.2 -norm is delivered onto the normalized vector output device (4).
