An image-forming apparatus equipped with an optical means, an electrostatic image-forming means and a control means. The optical means projects a scanned light beam to be controlled according to an image to be formed. The image-forming means receives the scanned light beam projected from the optical means and forms an image corresponding to the scanned light beam. The control means controls the optical means and the image-forming means.

摘要:
A semiconductor device comprising a signal transmission line of a microstrip structure, capable of increasing the characteristic impedance of the signal transmission line and reducing coupling between a plurality of signal lines. In a signal transmission line of a microstrip structure composed of a signal line and a ground plate, the capacitance between wires is reduced and the characteristic impedance can be increased by forming holes in the signal line or in the ground plate. The coupling between a plurality of signal lines can also be reduced.

A heat shield plate for a substrate annealing apparatus is provided with a horizontally supported flat-plate-like substrate 1, a heater 5 positioned above the substrate to heat the upper surface of the substrate with radiation heat, and a heat shield plate 10 horizontally movable between a shielding position where the substrate is shielded from heater and an open position out of the shielding position. The heat shield plate 10 is composed of a structural member 12 made of a low thermal expansion material (carbon composite material) which is hardly deformed due to a temperature difference in the shielding position, and a heat insulating member 14 which covers the upper surface of the structural member and keeps the surface at an allowable temperature or below.

It is possible to provide a circuit and method for carrying out a parallel test using BOST (Built Out Self Test). The circuit includes first transfer circuits (11-1, 11-2, . . . ) that extract a data pattern supplied to a complete operating article chip (10) in a BOST (3) from the BOST and that successively transmit the data pattern in response to a clock signal, and second transfer circuits (12-1, 12-2, . . . ) that extract output data from the complete operating article chip (10) as an expectation value pattern and that successively transmit the expectation value pattern in response to the clock signal. The data pattern supplied to the complete operating article chip (10) is applied to one chip to be measured (10-1) and the data pattern from a corresponding stage of the first transfer circuits (11-1, 11-2, . . . ) is applied to each of other chips to be measured (10-2, . . . ). A comparator (14-1) compares output data from the one chip to be measured (10-1) to the output data from the complete operating article chip (10) to decide whether or not they coincide. Corresponding to the other chips to be measured (10-2, . . . ), a comparator (14-2, . . . ) compares respective output data from the other chips to be measured to the expectation value pattern from the corresponding stage of the second transfer circuits (12-1, 12-2, . . . ) to decide whether or not they coincide.
