摘要:
A duplex heat exchanger of the so-called stacked type has in principle a plurality of plate-shaped tubular elements (1) which are stacked side by side or one on another and a plurality of fins (2) each intervening between the adjacent tubular elements. Each tubular element is composed of flat tubular segments (3a, 4a) separated from each other and each communicating with one of bulged header portions (3b, 4b) of the tubular element, so that flow paths (3, 4) for heat exchanging media are formed through each tubular element. Two or more unit heat exchangers (X, Y) are defined integral with each other within the duplex heat exchanger, since the adjacent tubular elements (1) communicate with each other through the header portions (3b, 4b).

Provided is a dereverberation system or the like which copes with an arbitrary condition flexibly and is capable of recognizing a sound or a sound source signal. According to the dereverberation system, an inverse filter (h) is set by using a pseudo-inverse matrix (R+) of a non-square matrix (R) as a correlation matrix of input signals (x). On the basis of the inverse filter (h) and an estimated correlation matrix (R̂) generated according to a window function (w), an error cost (J(h) between a correlation value of the input signals (x) and output signals (y) and a desired correlation value (d) is calculated. On the basis of the error cost (J(h)), the inverse filter (h) is adaptively updated according to a gradient method.

An image forming apparatus includes a rotatable image bearing member, and a transfer material support having a circumferential length an integer multiple of that of the image bearing member for supporting and transporting a transfer material. An image formed on the image bearing member is transferred at a transfer position onto the transfer material supported by the transfer material support. The image forming apparatus also includes a press member for pressing the transfer material support against the image bearing member at the transfer position. A varying device varies a relative position between the peripheral surfaces of the image bearing member and the transfer material support without shifting the transfer material support away from the image bearing member. A release device releases pressing of the transfer material support against the image bearing member by the press member when the varying device varies the relative position of the image bearing member and the transfer material support.

A magnetic brush developing device for an electrostatic copying apparatus wherein a magnetic brush is formed on a surface of a developing roller includes a magnet roller rotating inside of a cylindrical sleeve which is located adjacent to the surface of an electrostatic latent image retaining member to which a developing material is circumferentially applied. The magnet roller stops at a rotary angle such that a bristle of the magnetic brush on the sleeve is spaced from the surface of the electrostatic latent image retaining member, whereby a bristle of the magnetic brush is prevented from remaining in contact with the electrostatic latent image retaining member. Thereby, the developing material is prevented from causing the surface of the electrostatic latent image retaining member to change chemically, the developing material is prevented from causing the electrical characteristics of the surface to fail, and the developing material is prevented from adhering to the surface.

摘要:
A path generator includes a map generator for generating a map for a movement space based on information on the position and shape of a mobile object, an obstacle, and a target object. It also includes a composite potential generator for calculating an attractive potential and a repulsive potential based on relative positional relationship among the mobile object, the obstacle, and the destination position, and generating a composite potential that is a sum of the attractive potential and the repulsive potential. A local minimum determination unit performs a path search in the map based on the composite potential and determines whether a convergence position of the path search is a local minimum. If it is, a phantom potential generator generates a phantom potential to be added to the potential of the convergence position. If the convergence position is the destination position, a path generator generates a movement path for the mobile object based on the result of the path search.
