Title: Laser beam surface treatment of circumferential part
Inventor: KANAZAWA TAKAAKI
IPC: B23K26/064
Filed: 1985-07-25
Abstract: PURPOSE:To subject the circumferential part of a material to be treated to a uniform and defectless surface treatment by forming laser light to a luminous flux of an annular section having a prescribed axial line by an optical system and moving the same along the common axial line of the optical system and the circumferential part of the material to be treated. CONSTITUTION:The laser light 2 is made incident on a circular conical mirror 1 from above to below. The laser light 2 is reflected by a reflection surface 1a and is emitted in the annular sectional shape having the axial line 2a. The emitted light is focused onto the circumference centering at the axial center of an inside peripheral surface. The focused light is positioned to the circumferential part 4a at the top end edge of the surface 4 and the laser light 2 is irradiated into the circumference in the circumferential part 4a. The surface of the circumferential part 4a is subjected to the surface treatment such as build-up welding and alloying treatment by such laser light 2. The radius of the circumference of the laser light to be irradiated to the material 5 to be treated increases if the circular conical mirror 1 is moved upward along the axial center of the surface 4, i.e., the axial center of the circumferential part 4a. The plane between the circumferential parts 4a and 4b is thus beautifully surface-treated.

Title: Substrate treatment device
Inventor: SUGIMOTO KENJI
IPC: B08B3/04
Filed: 1995-06-30
Abstract: PURPOSE: To provide a device which enables a chemical solution to be discharged uniformly and hardly generates contamination. CONSTITUTION: This substrate treatment device is composed of a treatment tank equipped with a container part 41 which constitutes a treatment tank body and a pair of discharge nozzles 43, 44 for a treatment liquid, arranged in a mutually opposed position at the bottom of the container part 41. In addition, both container part 41 and discharge nozzle 43, 44 are formed of PEEK material. Consequently, it is possible to efficiently prevent the internal wall surface of the treatment tank 4 or the discharge nozzles 43, 44 for a treatment liquid from being corroded by a chemical solution, when an oxide film on the substrate surface is etched using, for example, a dilute hydrofluoric acid as a chemical solution for the treatment of a substrate. Consequently, the contamination hardly occurs when treating the substrate and a uniform quantity of treatment liquid is always discharged.  Besides the treatment tank 4 can be prepared easily and accurately by forming the tank 4 with a resin material.

Title: Device and method for processing printing
Inventor: YOSHITOMI ATSUSHI
IPC: B41J29/38
Filed: 1995-06-30
Abstract: PURPOSE: To prevent the waste of paper caused by the change of printing contents. CONSTITUTION: When printing data from an application are inputted (step S602), a printer driver processes those data and discriminates whether they are the partition data of pages or not (step S604). When those data are the partition data of pages, the data up to that partition are collected into one piece and a printing job is prepared (step S605). The prepared job is outputted to a spooler (step S606) and that processing is repeated until the printing data are finished. Thus, since the job of a desired page to be interrupted is interrupted and deleted from the spooler when there is such a page, only the desired page is canceled as an object and corrected and printing can be performed again later. Therefore, the wast of paper can be suppressed to a minimum.
