  • Patent number: 10029396
    Abstract: Dot pattern perforations predetermined according to a type (kind and carving size) of a workpiece are formed in a part of a body of an attachment where the workpiece is to be set. A seal carving apparatus detects the dot pattern of the mounted attachment by means of photosensors to identify the type of the workpiece. This makes it possible to check consistency between type information on the workpiece input by a customer and type information identified from the dot pattern to prevent mismounting of the attachment or an erroneous carving operation.

  • Patent number: 9993972
    Abstract: A seal carving apparatus includes a thermal head having a plurality of heat generating elements disposed in lines, and thermal drive control means that performs a control process of selectively and thermally driving the individual heat generating elements while moving the thermal head and a porous material in relative to each other with the thermal head being in abutment with the porous material, thereby forming a seal face on the porous material. The thermal drive control means controls a pulse time width for thermally driving the individual heat generating elements of the thermal head under pulse width modulation control based on gradation image data having a gradation value, thereby forming a seal with a gradation on the porous material.

  • Publication number: 20160263627
    Abstract: A process fluid circulation type processing system has a processing apparatus that supplies a process fluid to a workpiece held on a chuck table. A process fluid supplying apparatus adds a surface active agent to pure water to produce the process fluid at a predetermined concentration and then supplies the process fluid to the processing apparatus. A pure water generating apparatus removes processing dust and impurities including the surface active agent from waste fluid discharged from the processing apparatus to thereby generate the pure water and then supplies the pure water to the process fluid supplying apparatus. The process fluid supplying apparatus includes a pure water passage, a pure water flow meter for measuring the flow rate of the pure water, and a surface active agent supplying unit for supplying the surface active agent to the pure water downstream of the pure water flow meter.

  • Publication number: 20050096934
    Abstract: The part lifetime management system includes a parts server and a parts lifetime managing server. Parts server stores various data of parts used to repair car, automobile, etc. When the drawing of a repair part is released, future integration plan of the part is decided and inputted to the parts lifetime managing server with an integration condition. In the future, when the integration condition is satisfied, the parts lifetime managing server outputs the instruction to integrate a part to predetermined terminal. Then, the supply of a pre-integration part is stopped and changed to post-integration part so that the number of kinds of repair parts are reduced.
