  • Publication number: 20240128683
    Abstract: The CPA-attached connector 1a includes a connector body 11 and a CPA member 12. The connector body 11 includes a temporary latch portion 112 for the CPA member 12, a full latch portion 113 which, before the mating with a mating connector, restricts full latch of the CPA member, and which, during the mating, cancels restriction of the full latch by the mating connector, and a hood portion 114 configured to cover, in a manner of a canopy, a portion of the CPA member 12 in the full latch state. The CPA member 12 includes a CPA body 121 and a finger rest portion 122 provided on the CPA body 121, a portion of the finger rest portion 122 being exposed from the hood portion 114 even in the full latch state, an inclined surface 122a being formed in the exposed portion to incline toward a central axis of the connector body 11 in accordance with a distance from the hood portion 114.

  • Patent number: 11791070
    Abstract: 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.

  • Patent number: 4656140
    Abstract: 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.

  • Patent number: 4378375
    Abstract: 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.

  • Patent number: 4364960
    Abstract: 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.
