Publication number: 20230384230Abstract: An object of the present invention is to provide a kit for making an electron donor visible and a method for making an electron donor visible, stably visualizing coloring of a site to which an electron donor is adhered over a certain period of time and causing no deterioration in appearance due to remaining of a dye. The kit for making an electron donor visible of the present invention includes a liquid A containing a coloring component including an electron donating colorant and a solvent and a liquid B containing a bleaching component including an electron acceptor and a solvent in combination. In the present invention, the liquid A and the liquid B are sprayed onto an adhesion surface of an electron donor to reveal an adhesion site of the electron donor.Type: ApplicationFiled: August 10, 2023Publication date: November 30, 2023Applicant: SHACHIHATA INC.Inventors: Hideshi IMAI, Norihiro MINAMIDA

Patent number: 10832301Abstract: A host computer, a plurality of thermal carving machines, and a user terminal are connected to a network. The host computer includes seal image creation means that permits edition of a seal image using the user terminal, site selection means that allows a user to specify one site from a site candidates list, ID issuing means that issues an order ID for identifying the contents of an order, and order information registration means that registers the issued order ID and order information in a database. A control device of the thermal carving machine includes order acceptance means that accepts an order ID input when information on the input order ID is registered in the database, and carving control means that performs seal carving of a stamp based on seal image data associated with the order ID.Type: GrantFiled: December 29, 2015Date of Patent: November 10, 2020Assignee: SHACHIHATA INC.Inventors: Eiji Abe, Masayoshi Uchida

Patent number: 10183480Abstract: Provides is a seal surface carving apparatus capable of carving a seal surface using only a single attachment irrespective of a size of a stamp. A porous impression die having a seal surface to be carved is set on a dedicated attachment, and is loaded in a seal surface carving apparatus. A fitting projection fit to a bottom portion of the impression die is formed on the attachment, and impression dice having various sizes may be set. In addition, a slit hole extending in a conveyance direction is formed in an impression die setting portion of the attachment. Impression die size determination means of the seal surface carving apparatus determines a size of the impression die by detecting a position at which the impression die blocks the slit hole.Type: GrantFiled: January 12, 2017Date of Patent: January 22, 2019Assignee: Shachihata Inc.Inventors: Eiji Abe, Takayuki Mitsuya

Patent number: 10029396Abstract: 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.Type: GrantFiled: October 16, 2015Date of Patent: July 24, 2018Assignee: Shachihata Inc.Inventors: Eiji Abe, Masayoshi Uchida

Patent number: 9993972Abstract: 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.Type: GrantFiled: September 13, 2017Date of Patent: June 12, 2018Assignee: Shachihata Inc.Inventors: Eiji Abe, Masayoshi Uchida

Patent number: 9975367Abstract: A reverse type stamp includes an outer cylindrical body, an inner cylindrical body which is movable relative to the outer cylindrical body, an elastic member that constantly urges the inner cylindrical body in a protruding direction inside the outer cylindrical body, an inversion body which is reversed and returned in synchronization with the relative movement, and a print body which is joined to the inversion body. When the outer cylindrical body is pressed down while the inner cylindrical body stands on a paper surface, the inversion body is reversed inside the inner cylindrical body for an imprinting operation. An ink pad is provided inside a movable container inside a cartridge. The movable container is elastically supported inside the cartridge by a coil spring provided at a rear surface thereof. Since contact between the ink pad and the print body is buffered, the sagging of the ink pad can be prevented.Type: GrantFiled: March 7, 2017Date of Patent: May 22, 2018Assignee: Shachihata Inc.Inventor: Takuya Koide

Publication number: 20180086124Abstract: Provided is a stamp unit comprises a case that accommodates an ink occluding member and a frame on which an impression member formed of a porous film is tightly stretched, and a leaf spring is provided between the case and the frame. By an elastic repulsive force of the leaf spring, the impression member and the ink occluding member are constantly separated from each other, and the ink is not allowed to penetrate the impression member during distribution. In this way, even when an unexpected external force is applied to an unprocessed stamp unit, the impression member and the ink occluding member do not come into contact with each other, and penetration of ink into the impression member is prevented from starting.Type: ApplicationFiled: September 12, 2017Publication date: March 29, 2018Applicant: SHACHIHATA INC.Inventor: Takayuki MITSUYA
