Publication number: 20220319766Abstract: In the multi-layer coil component, the via conductor electrically connecting the coil layers adjacent to each other in the stacking direction of the element body protrudes from the coil region toward the side surface of the element body when viewed from the stacking direction of the element body. Therefore, the coil has a concave-convex portion. When a force is applied to the multi-layer coil component from the outside, the force is dispersed in the concave-convex portion of the coil, and thus defects are less likely to occur in the coil than in a coil in which the side of the side surfaces is flat.Type: ApplicationFiled: March 22, 2022Publication date: October 6, 2022Applicant: TDK CORPORATIONInventors: Akihiko OIDE, Makoto YOSHINO, Tomoki OKADA, Hideki SAITOU, Seiji OSADA, Kazuhiro EBINA, Kunio ODA, Takashi ABE, Akio SHIBATA, Kazuo IWAI

Publication number: 20220310312Abstract: In the multi-layer coil component, the lead conductor is exposed from the end surface of the element body and is connected to the external electrode provided on the end surface. When the lead conductor is led out to the end surface of the element body, the lead area can be easily increased as compared with the case where the lead conductor is led out to the side surface of the element body. Therefore, by connecting the coil and the external electrode via the lead conductor, high connectivity between the coil and the external electrode is achieved.Type: ApplicationFiled: March 18, 2022Publication date: September 29, 2022Applicant: TDK CORPORATIONInventors: Akihiko OIDE, Makoto YOSHINO, Tomoki OKADA, Hideki SAITOU, Seiji OSADA, Kazuhiro EBINA, Kunio ODA, Takashi ABE, Akio SHIBATA, Kazuo IWAI

Publication number: 20160058062Abstract: In conventional defrosting methods such as running water and microwave defrosting, dripping has arisen, affecting flavor and color, and so frozen foods have been evaluated poorly. Also, natural defrosting and refrigerator defrosting require at least two hours, and similarly dripping has arisen and so the reputation has been poor. The objective of the present invention is to perform defrosting of a frozen food such as meat or fish in a short period of time without using thermoelectricity such as electricity.Type: ApplicationFiled: December 27, 2013Publication date: March 3, 2016Inventor: Kazuo IWAI

Patent number: 6554620Abstract: The present invention provides a disinfectant/sterilizing composition which includes hinokitiol as the active ingredient. The composition has enhanced solubility of the hinokitiol in water without the need for alcohol as a solubilizing enhancing ingredient due to the presence of aloe vera extract, green tea extract, low striped bamboo extract and dokudami extract. In addition, the solubility of the hinokitiol in water is further enhanced by the additional inclusion of glycerin fatty acid ester surfactant and cara saponine emulsifier. In addition to enhancing the solubility of the hinokitiol in water, the above-noted plant extracts also serve to enhance the biocidal effect of hinokitiol and avoid the objectionable strong odor usually associated with hinokitiol compositions.Type: GrantFiled: October 15, 2001Date of Patent: April 29, 2003Inventor: Kazuo Iwai
