Publication number: 20230411069Abstract: An electronic component includes an element body, an electric element embedded inside the element body, and an electrode terminal connected to the electric element so as to be exposed to an outer surface of the element body. The electrode terminal includes a terminal body continuously and integrally formed with a wire of the electric element embedded inside the element body and extending in a planar shape along a main surface of the element body. The wire is drawn out to an outside of the element body from the main surface of the element body to form the electrode terminal.Type: ApplicationFiled: May 19, 2023Publication date: December 21, 2023Applicant: TDK CORPORATIONInventors: Shintarou KOIKE, Kazushige TOHTA, Takuto KAZAMA, Masashi GOTOH

Patent number: 9118011Abstract: An oxide material having a langasite-type structure having a desired surface condition and a desired outer shape is obtained stably. By adding at least one selected from the group consisting of Ir, Pt, Au, and Rh to a raw material which is a composition used for producing a desired oxide material as an additive element, it is possible to control the wettability between a die portion at a bottom end of a crucible and a melt of the raw material, thereby implementing stable production of the oxide material while controlling the wetting and spread of the melt of the raw material leaked out through a hole of the crucible.Type: GrantFiled: October 12, 2011Date of Patent: August 25, 2015Assignee: TDK CorporationInventors: Ko Onodera, Kazushige Tohta, Masato Sato, Akira Yoshikawa, Yuui Yokota

Patent number: 7323053Abstract: It is an object of the present invention to provide a pulling-down apparatus that can breed a crystal having good characteristics of scintillation. The apparatus retains in a container that can control an atmosphere a melting pot having a narrow hole at the bottom side thereof, an induction heating device, and a seed-holding device that holds a seed and is pulled down so that a crystal formed successively to the seed is pulled down. Concurrently, imaging devices are arranged that can pick up images of a solid-liquid interface between the crystal and a melt material, from different directions, and the seed-holding device can be travel along directions perpendicular to respective image pickup directions in a horizontal plane.Type: GrantFiled: January 23, 2006Date of Patent: January 29, 2008Assignee: TDK CorporationInventors: Kazushige Tohta, Kou Onodera, Takeshi Ito, Tsuguo Fukuda, Akira Yoshikawa

Patent number: 7165317Abstract: The present invention is an object to provide an apparatus or a method making it possible to easily effect connection between additional electrodes, etc. and lead electrodes when performing a processing for achieving a predetermined throat height value or crown processing or the like and making it possible to measure the requisite lapping amount. For achieving the object, a flexible electrode extension sheet is used which consists of a portion for retaining a ceramic bar in which element portions are formed and a portion where there are formed wirings respectively in correspondence with the elements and adapted to be connected to these elements, in which these wirings, which can be easily connected to an external measurement system, are electrically connected to the elements, whereby the lapping amount is easily obtained from the characteristic amount of the elements in the lapping process.Type: GrantFiled: June 15, 2001Date of Patent: January 23, 2007Assignee: TDK CorporationInventors: Hiroshi Shindo, Akio Ogawa, Kazushige Tohta

Patent number: 6991513Abstract: The present invention relates to a lapping apparatus and a lapping method that may effect further machining in response to each element on a ceramic bar to the ceramic bar that is largely locally lapped and may reduce a cost needed for machining without any jig for holding the ceramic bar. The ceramic bar is held by a surface of an elastic member made of rubber or the like. A plurality of actuators are arranged on a back surface of this elastic member. When the ceramic bar is depressed against the lapping surface, a specific portion of the ceramic bar is deformed or strongly deformed through the elastic member by these actuators to thereby make it possible to perform the lapping in response to each element.Type: GrantFiled: June 15, 2001Date of Patent: January 31, 2006Assignee: TDK CorporationInventors: Kazushige Tohta, Hiroshi Shindo, Akio Ogawa, Osamu Fukuroi, Takashi Fujii
