摘要:
A focal plane shutter for a camera comprises opening and closing blade units operable to open and close a shutter opening of the camera. Each blade unit has a leading blade and trailing blades in superposed relation to the leading blade. The leading blade and the trailing blades are supported by arm members through hollow pivot pins. The hollow pivot pins supporting the leading blade of each blade unit are covered by the trailing blades. Due to the use of hollow pivot pins, the overall weight and driving force of the blade units are effectively reduced to thereby make the shutter free of operational impact without light leakage.

The present invention relates to a stabilized proline transporter Put4 obtained by gene mutation and a gene encoding the same, as well as a Saccharomyces yeast strain which is obtained by yeast transformation with the gene and is capable of efficiently using proline in a source material such as wort. The stabilized mutated proline transporter Put4 can be used to achieve efficient use of nitrogen sources such as poorly assimilable proline contained in source materials (e.g., wort) for alcohol beverages. Fermentation using yeast capable of taking up a wide variety and large amounts of nitrogen sources facilitates carbon source assimilation and allows improvement of productivity for alcohol beverages. Moreover, the use of poorly assimilable nitrogen sources leads to resource savings and enables environmentally friendly production of alcohol beverages.

It is an object of the present invention to provide fermented beverages that give no sweetness in aftertaste and which have less off-flavors by a technique that will not affect the principal taste and aroma characteristics and which is highly acceptable to consumers.To attain this object, the proportion of trisaccharides in the assimilable sugars in the fermentation raw material solution or fermenting solution is adjusted, such that the yet-to-be assimilated sugars which remain in the fermenting step will not consist mainly of trisaccharides. Specifically, fermentation is performed while the proportion of trisaccharides in assimilable sugars in the fermentation raw material solution is adjusted to be no more than 25 wt %.

It is a common concern among beverages to avoid or prevent off-flavors (unpleasant smells) from developing during a yeast-based fermentation step. The present invention relates to low-alcohol beverages produced through a fermentation stopping process and provides a method for producing fermented beverages with less off-flavor and with an excellent aroma. The L-methionine concentration and the free amino nitrogen level (FAN level) in wort are adjusted to reduce the hydrogen sulfide concentration and the T-VDK concentration, thus enabling the production of fermented beverages with less off-flavor, i.e., sulfur and diacetyl smells.

Disclosed herein is a light receiving apparatus, including: a light receiving section including a light receiving element; a transparent part; and a light guiding part inserted in the groove; the groove having, on the front face side, a side face formed as an arcuately curved face convex toward the front face side and having the same shape in any cross section perpendicular to the front face and also to the depthwise direction of the groove; the light guiding part having a side face opposing to the side face of the groove on the front face side and formed as an arcuately curved face which is convex toward the front face side in a state wherein the light guiding part is inserted in the groove and which has the same shape in any cross section perpendicular to the front face and also to the depthwise direction of the groove.
摘要:
A novel technique is provided for drying a yeast for brewing and a method of producing alcoholic beverages by using the yeast. It is intended to provide a method of producing a dry yeast which has the optimum fermentability when directly used in fermentation and gives an appropriate flavor without needing prepropagation, and a method of producing alcoholic beverages by using the yeast.A method comprising incorporating a stabilizer such as trehalose into a yeast which has been recovered from the fermentation step, and, if desired, further incorporating glycerol into the yeast to thereby lower the water activity in the cells, and then dehydrating/drying the yeast while sustaining a high viable cell ratio and favorable fermentability; and alcoholic beverages produced by using the yeast.
摘要:
When a driving member is rotated counterclockwise by a single motor with a pair of sectors biased in the closing direction by a biasing spring, a first driving pin causes an operating lever to rotate clockwise. The pair of sectors pivot in opposite directions to each other in association with the driving lever to reach a first position where the sectors are fully open without overlapping the lens opening. When the driving member is rotated clockwise, a second driving pin also causes the operating lever to rotate clockwise. The pair of sectors pivot in opposite directions to each other to reach a second position, that is, a half-open position where an opening smaller than the lens opening is obtained. At this time, The second driving pin abuts on a part of one sector to restrain the displacement of the driving member. Accordingly, the driving member is prevented from overrunning, and no hunting occurs.
