Title: Preparation of yeast extract
Inventor: KAMATA KOUZOU
IPC: A23L1/28
Filed: 1982-06-09
Abstract: PURPOSE:To prevent the unagreeable odor and color of yeast extract, by the pretreatment of raw yeast with an alcohol solution. CONSTITUTION:In the preparation of yeast extract, the yeast used as a raw material is pretreated with an alcohol solution having a concentration of >=10% by contacting the yeast with the solution at <=40 deg.C for <=1hr, and yeast is separated from the alcohol solution. The undesirable components such as odorous components, colored components, etc. are transferred to the alcohol by the treatment. Since the yeast odor is removed from the raw material, and the color is lightened by this method, the obtained yeast extract is free of the unagreeable odor and color which are inevitable to conventional yeast extract. Furthermore, the contaminant bacteria are removed from the yeast, the use of the solvent such as ethyl acetate, toluene, etc. becomes unnecessary, and the bitter hop taste can be reduced or eliminated.

Filed: 1980-07-16
Abstract: PURPOSE: To prevent the production of noise, by a method wherein an overflowing water is caused to flow down along a guide plate, and is reduced in shock against a river bed.  
     CONSTITUTION: An upper surface of a sliding surface of a river bed 6 is formed in a surface stretching out along a curve of a current guide plate 5 so that it smoothes a slide of a current guide plate 5 and betters stability when it falls down a river bed. A rail 11 is recessed in a moving direction such that it slightly emerges from the river bed. Thus, the current guide plate 5 slides on the rail 11. Water, which exceeds a given level of storage water 12 dammed up by a sluice gate, overflows a gate, and after it reaches a convex curve 10 of the current guide plate 5, a current direction is turned and the water flows into a current at a downstream side along a warping curve at a narrow flow-in angle. As a result, water, reaching the river bed, runs obliquely against the river bed to produce no shock, and thereby the water is reduced in a shock sound.

Title: Method and apparatus for recording color image in multi-color printing
Inventor: ETSUGERUTO YUNKU
IPC: G03F3/08
Filed: 1983-06-03
Abstract: Method and apparatus for recording color pictures wherein color proofs are made before the actual printing for quality control in multicolor printing processes. The color pictures are exposed on a chromatic material wherein the exposed colors must coincide with the colors which are later to be printed on paper. So as to achieve the color equivalent color picture exposure, the required color density values for the chromatic material of the selected printed and exposed colors are identified with a visual or mensurational comparison of the CIE coordinates. The identified color density values for the exposed colors are allocated to the corresponding color separation values of the colors to be printed and during recording the allocated color density values are utilized instead of the color separation values and are converted into signals for driving a color exposure unit for example a proof recorder.
