Patent number: 11791070Abstract: An NTC thermistor element is of less than 0402 size. A first internal electrode is connected to a first external electrode. A second internal electrode is separated from the first internal electrode and is connected to a second external electrode. A third internal electrode opposes the first and second internal electrodes and is not connected to the first external electrode and the second external electrode. A shortest distance between the first internal electrode and the third internal electrode and a shortest distance between the second internal electrode and the third internal electrode are smaller than a shortest distance between the first internal electrode and the second internal electrode, a shortest distance between the first external electrode and the third internal electrode, and a shortest distance between the second external electrode and the third internal electrode, and are less than or equal to ¼ the thickness of the thermistor body.Type: GrantFiled: September 28, 2020Date of Patent: October 17, 2023Assignee: TDK CORPORATIONInventors: Daisuke Tsuchida, Takehiko Abe, Yoshihiko Satoh, Koki Yamada

Patent number: 4656140Abstract: A method for measuring the alcohol concentration of an acetic acid fermentation broth which comprises (a) forming a sample gas containing volatile components present in the acetic acid fermentation broth, the volatile componentscomprising alcohol and acetic acid; (b) passing the sample gas through an absorption column packed with a material which binds acetic acid whereby the acetic acid is absorbed on the material; (c) passing the sample gas which has passed through the absorption column to a gas sensor for measuring the alcohol content of the gas by outputting an electrical signal which correlates to the alcohol content of the sample gas; and (d) determining the alcohol content of the sample gas in response to the electrical output signal from the gas sensor.Type: GrantFiled: November 8, 1984Date of Patent: April 7, 1987Assignee: Nakano Vinegar Co., Ltd.Inventors: Mikio Yamada, Masahiro Mizuno, Yoshinori Tsukamoto, Koki Yamada

Patent number: 4378375Abstract: Vinegar having an acetic acid concentration higher than 20 percent weight by volume is produced in a submerged fermentation by maintaining the temperature of a fermenting broth at 27.degree.-32.degree. C. until the acetic acid concentration of the fermenting broth (after the initiation of fermentation) reaches 12-15 percent weight by volume. Then the temperature of the fermenting broth is lowered by 0.5.degree. C. to 2.degree. C. Fermentation is continued at the lower temperature until the concentration of acetic acid increases by between 0.05 to 2 percent weight by volume. At this time, the temperature is again reduced by from 0.5.degree. C. to 2.degree. C. The fermentation is continued, with subsequent temperature reductions of from 0.5.degree. C. to 2.degree. C. each time that the concentration of acetic acid in the fermentation broth increases by 0.Type: GrantFiled: October 10, 1980Date of Patent: March 29, 1983Assignee: Nakano Vinegar Co., Ltd.Inventors: Yoshio Kunimatsu, Shoji Ohmori, Hiroshi Masai, Koki Yamada, Mikio Yamada

Patent number: 4364960Abstract: A finished vinegar having an acetic acid concentration higher than 20 percent weight by volume is produced by repeating a fermentation cycle wherein a broth is fermented at 27.degree.-32.degree. C. in a 1st submerged fermentation tank by a continuous batch process, and, when the acetic acid concentration of the fermenting broth reaches 12-15 percent weight by volume, the large part of the fermenting broth in the 1st fermentation tank is withdrawn and charged in a 2nd submerged fermentation tank. The 1st fermentation tank is recharged with a mash and the fermentation of the fermenting broth in the 2nd tank is continued under aeration while lowering the temperature of the fermenting broth in such manner that the final fermentation temperature does not fall below 18.degree. C. and the lowering temperature does not become higher than the temperature once lowered.Type: GrantFiled: September 30, 1980Date of Patent: December 21, 1982Assignee: Nakano Vinegar Co., Ltd.Inventors: Yoshio Kunimatsu, Hajime Okumura, Hiroshi Masai, Koki Yamada, Mikio Yamada
