摘要:
An electric-component mounting system wherein a determining device is operated for presently required operations of working devices disposed on a common main body, to determine a cycle-time-determinant working device which determines a cycle time of the system such that the cycle time is determined by a required operating time of the cycle-time-determinant working device as calculated when the presently required operation is performed at predetermined maximum acceleration and deceleration values or a predetermined maximum operating speed, and a slowdown device determines actual acceleration and deceleration values or an actual operating speed of each of non-cycle-time-determinant working device, so as to be lower than the predetermined maximum acceleration and deceleration values or operating speed thereof, such that the presently required operation of each non-cycle-time-determinant working device can be completed within the cycle time determined by the cycle-time-determinant working device.

There is provided an information processing system in which files on plural file servers having different file management manners can be efficiently accessed by a single client program, a control method for the information processing system, and a storage medium for storing programs for performing the control. A gateway program 20 is provided on a first server information processing device 120, and an agent program 30 which is operated in conformity with the gateway program 20 is provided on a second server information processing device 130, whereby a copy of the directory structure of files on the second server information processing device is created on the first server information processing device 120. In addition, at the time when the copy is created, data in a file are not copied, and the data copy is performed only when the file is opened by an application program 8a of a client information processing device 110.

An electric-component mounting system including a component-holding device for holding an electric component, a board-supporting device for supporting a printed-wiring board on which the electric component is mounted, a first relative-movement device operable to move the component-holding device and the board-supporting device relative to each other in a first direction parallel to a surface of the board supported by the board-supporting device, a second relative-movement device operable to move the component-holding device and the board-supporting device relative to each other in a second direction which intersects the surface of the board; and a control device including a positioning portion operable to select one of a plurality of different control targets which is used for the first relative-movement device to establish a predetermined relative position between the component-holding device and the board-supporting device, and wherein the positioning portion selects one of the different control targets, depending upon a pattern of control of an operating speed of the first relative-movement device.
摘要:
A mounting system for an electric component operates by transferring the electric component from a component supply device to a suction nozzle of a component-holding head on a circuit substrate. A relative position between a sucking surface of the suction nozzle and an axis of rotation of the component-holding head is obtained. A component-holding head and the component supply device are moved relative to each other on the basis of the obtained relative position, so as to minimize an error of relative positioning between the sucking surface and a predetermined sucking position of the electric component positioned at the component-supply portion. The head and the component supply device are then moved toward each other, for transferring the electronic components from the component supply device to the suction nozzle.

摘要:
A particle size distribution measuring apparatus includes a source of laser light for providing a laser beam to a sample cell that can hold a sample to be measured. A condenser lens converges the laser beam towards the sample cell along an optical axis. The position on the other side of the sample cell is a ring detector unit that can be aligned with the optical axis to measure light intensity at relatively small scattering angles from contact with particles in the sample cell. An array of detectors can be operatively positioned on a substrate with appropriate amplifying multiplying and analog to digital conversion capacity for measuring light intensity at relatively large scatter angles. The outputs of the ring detector unit and the array of detectors can be used to determine the particle size distribution of particles in the sample.
摘要:
A cooperative adaptive low noise television system provides that, prior to transmission, the composite video is separated into chroma and luminance components. The luminance signal is adaptively pre-emphasized, with the amount of pre-emphasis being determined by the luminance transitions level, so that small transitions have more pre-emphasis than large ones. In the receiver, a received luminence signal is submitted to adaptive deemphasis in order to precisely cancel the adaptive pre-emphasis provided prior to transmission, thus reducing transmission noise while restituting a luminance signal free of pre-shoot, over-shoot or resolution losses.

A television system, in which a picture is transmitted from an oblong screen to a television screen having an aspect ratio of 3:4, which is different from that of the oblong screen, and wherein no-picture portions are developed within upper and lower sections of the television screen, signals are transmitted into such upper and lower no-picture portions of the television screen in accordance with detected non-moving and moving picture portions of the oblong screen so as to improve the resolution of the picture image displayed upon the television screen.
摘要:
An extruded synthetic resin foam comprises a cell structure of substantially two different cell sizes, the smaller size being not more than about 0.25 mm while the other size is from about 0.4 to about 1 mm. The cells are dispersed in an island in the sea manner. A foam such as a styrenic foam is produced by forming a mixture of synthetic resin, a fine mineral powder having hydroxyl groups, and a cell controlling agent, incorporating a volatile foaming agent and extruding the mixture to form a foam. The powder has a particle size of not more than 1000 nm and may be a silica having silanol groups.
