摘要:
The present invention is an apparatus for filling a multi-powder including a powder box (10) including a plurality of powder chambers storing a plurality of powders whose constituent compositions differ in a divided manner, and a gas feed pipe (14) disposed on the bottom side of the powder chamber and having an introducing hole for introducing a gas, wherein it can fill a plurality of the powders into a cavity (24) at once through the bottom openings of the powder box by introducing a gas through the introducing hole to substantially equalize the respective flow resistances of a plurality of the powders. Thus, it is possible to fill the powders whose constituent compositions differ at once without disposing them in a mixed manner.

A fuel supply duct, which supplies a mixed fluid of a solid fuel and carrier gas to one or more burners provided on the walls of a furnace, is provided with a branching part, and each of a plurality of branch ducts, which branch out from the branching part, is connected to a corresponding burner. Also a damper, with which the tilt angle with respect to the direction of flow of the mixed fluid can be changed, is positioned in the fuel supply duct at the upstream side of the branching part so that a mutual difference will arise in the solid fuel concentrations of the mixed fluid supplied to the respective branch ducts. A fuel distributor for fuel supply duct is thus arranged. The tilt angle of the above-mentioned damper is adjusted to increase the concentration of solid fuel in the mixed fluid supplied to a specific burner. At a burner to which the high solid fuel concentration is supplied, stability of ignition and stable combustion of the ignited flame can be obtained during low load operation.

A hologram recording medium and apparatus for and method of recording data on the recording medium. The recording medium is a card shaped hologram recording medium having an auxiliary recording area at a periphery of a main or user data recording area. Address information is recorded along one or two sides of the main or user data recording area. The recording medium may also be divided into a plurality of user data areas each having associated address data on the one or two sides. A recording location is determined by reference to the address information.

In an information processing apparatus, a user having no knowledge of a designer of an LSI modifies a floorplan of the LSI without deteriorating the performance of the LSI. The designer who designs the LSI uses a circuit designing apparatus to store circuit information including a functions of each of blocks constituting the LSI, a floorplan regarding allocation of the blocks, and evaluation indices which are the know-how of the designer, with being associated with each other. The user uses a floorplan modifying apparatus to modify the floorplan and to evaluate the modified floorplan according to the evaluation indices.
摘要:
A semiconductor storage device conducts a late-write operation. The semiconductor storage device comprises: a memory core circuit storing data; a data latch circuit storing preceding data corresponding to a preceding write-operation; an address compare circuit comparing a preceding address corresponding to the preceding write-operation and a present address corresponding to a present read-operation so as to determine whether the preceding address and the present address match each other; and a control circuit. The control circuit controls a test read-operation to read data from the memory core circuit regardless of whether the preceding address and the present address match each other.

In a synchronization system adopted in a synchronous-multisystem control apparatus including a plurality of systems operating synchronously with each other at a fixed control period, the synchronous-multisystem control apparatus can be operated in a single-system mode in the event of failures occurring simultaneously in some of the systems. The synchronous-multisystem control apparatus employs a plurality of control circuits each provided for one of the systems. Any particular one of the control circuits includes: a period-signal generating circuit for generating a period signal indicating a start point of a control period; a synchronization-reference selecting circuit for outputting a synchronization-reference signal by referring to period signals generated by the systems; and a control-period correcting circuit for correcting a control period of the particular system by forming a judgment on a synchronization shift of the period signal generated by the particular system from the synchronization-reference signal and keeping the control period as it is in case the synchronization-reference signal is not generated.

A tuning-fork type piezoelectric vibratory gyroscope includes a tuning fork having two arms and a base portion integrally formed with the two arms and having electrodes, and a supporting base supporting the base portion of the tuning fork. An adhesive layer joins the base portion and the supporting base together so that the tuning fork and the supporting plate are elastically integrated within a temperature range in which the gyroscope is used.
