摘要:
A method for controlling printing impact in an impact type dot printer which controls printing impact energy to be increase in case of normal density imprint function and to be decreased in case of high density imprint function in the controlling means of the impact type dot printer in which the printing stylus strikes the printing paper so that the printing paper can be prevented from being damaged during the high density imprint function.

A method of fabricating a polycrystalline silicon wafer, which method advantageously has the steps of radially outwardly flowing molten liquid of silicon base material on the wafer forming surface of a turntable mechanism by means of centrifugal force, thereby forming a thin molten liquid layer in a prescribed atmosphere, and cooling and solidifying the same. An apparatus for fabricating the wafer is used to carry out the method with a recover tray arranged at the wafer forming surface for receiving the excessive silicon liquid scattered, and a wafer tray placed on the recovery tray, and the wafer forming surface is cooled with coolant flowing in the wafer forming mechanism. Thus, large crystalline grains can be grown on the wafer in free states with the atmosphere from the inner surfaces of the casting mold as the conventional method.

Method of making a semiconductor device which includes applying a solution of a heterocyclic ring-containing polymer in an organic solvent to a desired surface of a semiconductor body and removing the organic solvent from the solution by heat thereby to form a coating of a polymer on the surface, wherein the polymer is a reaction product of a diamine represented by the formula: ##STR1## with a tetracarboxylic acid or anhydride of it. Since the coating exhibits good thermal stability and good electrical properties when applied to the surface of the semiconductor, it is useful as a passivating film.

At a contact step in a tool radius adjusting method, a reference portion of a movable body provided radially movably on a housing of a boring tool and a position adjusting reference member fixed on a machine tool are brought into contact by sliding the movable body relative to the housing so that the position of a cutting blade comes to a predetermined position in a direction to go away from a rotational axis. Then, at an adjusting step, the position of the cutting blade relative to the rotational axis is adjusted by changing the relative position between a tool spindle holding the boring tool and the position adjusting reference member in a direction to come close to each other by drive mechanisms of the machine tool used for positioning a spindle head with the tool spindle relative to a workpiece in machining the workpiece with the cutting blade.

A tool radius adjusting device executes an operation for adjusting the tool radius of a boring holder in parallel with execution of a machining program for executing an operation of a spindle head and an operation of a tool changer. A carrier control unit determines whether the tool changer is executing a tool changing process. When the tool changing process is not being executed, the carrier control unit allows the carrier device to execute an operation for picking the boring holder out from the tool magazine and an operation for returning the boring holder, of which the tool radius has been adjusted, to the tool magazine.
摘要:
An audio playback device includes an interruption-information storage memory which holds frame information at the time of an interruption of playback, a compressed-stream control section which calculates a start position of reading the compressed stream from a recording medium, and reads the compressed stream accordingly, a compressed-stream decode section which decodes the compressed audio stream and transmits decoding information on the frame to the compressed-stream control section as additional resume information, and an output control section which outputs a decoding result. When playback is restarted after an interruption, playback can be restarted without any section not played back in terms of time and without any frequency range not played back, by calculating the start position of reading the compressed stream based on both the additional resume information and the frame information at the time of the interruption, and by reading the compressed stream accordingly.
