Title: Printer control system
Inventor: FUKUNAGA MASAJIRO
IPC: G06F3/12
Filed: 1991-02-08
Abstract: PURPOSE:To print printing data larger than the capacity of a storage device, and to execute the spool of the printing data and output to a printer in parallel so as to speed up printing. CONSTITUTION:A printing job control part 2 receives the printing data from an application program 1a to 1n, and controls correspondence between the printing data and the application program as a printing job. When a spool file control part 3 receives the printing data from the printing job control part 2, it divides the printing data into plural groups of the spool files of small capacity for each printing job, and stores them. A spool file printing part 4 executes printing by a spool file unit as soon as the spool file corresponding to the printing job of the oldest generation is completed, and after the finish of this printing job, it shifts to the printing of the printing job of the second oldest generation.

IPC: B23K26/21
Filed: 1983-02-07
Abstract: PURPOSE:To decrease the thermal influence on a fine wire having high strength and the stress concentration in the end part of welding in laser butt welding of the fine wire and an equal thickness plate by irradiating a laser to the end part of the plate material apart slightly from the fine wire and welding both materials with the power increased at the beginning and end points. CONSTITUTION:A plate material having the thickness roughly equal to the diameter of a fine wire material having high strength is provided apart from the wire at about 1/2 of the plate thickness. The laser light for irradiating both surfaces by a mirror and a half mirror is moved to irradiate the end part of the plate material, thereby melting the end part and welding the same to the fine wire. The power of the irradiation at a beginning point 8a and an end point 8d is increased in this state. The weld zone having substantial curvature is thus obtd. in the end part 16 of welding and a local stress concentration is eliminated. The laser weld zone having high weld strength is thus obtd.

Abstract: PROBLEM TO BE SOLVED: To obtain a steel excellent in wear resistance and pitting strength by regulating the hardness in a specified depth from the surface before grinding in a steel subjected to carburizing treatment to >= a specified value and furthermore regulating the residual austenite content to <= a specified ratio. SOLUTION: Within 0.3 mm from the surface before grinding in a steel subjected to carburizing treatment, its hardness is regulated to >=750 HV, the residual austenite content is regulated to <=30%, and the concn. of carbon is regulated to 1.0 to 3.0 wt.%. As the material of the steel, a carbon steel or an alloy steel is used, and, if required, the elements to be added are incorporated therein. For increasing the caron concn. in the vicinity of 0.3 mm from the steel surface to form a grinding margin, it is held while heating at 1,000 to 1,250 deg.C and is subjected to carburizing treatment. At this time, for preventing the precipitation of network carbides, it is preferable that the carbon concn. does not exceed the A cm line. Then, it is cooled to the A1 point, is thereafter reheated to 750 to 870 deg.C and is quenched, by which coarsened austenitic crystal grains are refined to obtain a product in which the resudual content is regulated to <=30%.

IPC: G11B7/0045
Filed: 1988-01-28
Abstract: PURPOSE:To correctly specify a pit start end position whether a blank length is long or short and to decrease jitter by changing a bias optical output in accordance with the blank length at the time of recording. CONSTITUTION:A bias circuit 10 supplies a bias current IB variable by the blend length to a laser diode LD and makes it emit bias light to the extent of not melting a recording film when a transistor Tr2 is turned off, that is, at the time of forming a bland part or non-recording, namely, at the time of reproducing. Thus, when the blank length is long, the bias light is made higher, the cooling of a disk and the laser diode LD by the blank length being long is suppressed, the rise of a laser beam at the start end of a next pit becomes better and the melting shortage of the pit start end is solved. When the blank length is short, the bias light is made lower, the melting excess of the pit start end is solved. Thus, the jitter is decreased.
