Title: Production of glucose by saccharification of starch
Inventor: TAKASAKI YOSHIYUKI
IPC: C12R1/125
Filed: 1991-05-29
Abstract: PURPOSE:To promote saccharification reaction and efficiently produce glucose by saccharifying starch or liquefied starch in the presence of a pullulanase-like conjugated enzyme having glucoamylase activity and alpha-amylase activity. CONSTITUTION:A bacterium of the genus Bacillus which is a Bacillus subtilis TU strain (FERM P-684) is cultured to prepare a pullulanase-like conjugated enzyme having alpha-amylase activity capable of mainly decomposing starch into maltose and maltotriose. Starch or liquefied starch is subjected to saccharification reaction in the presence of glucoamylase, alpha-amylase beta-amylase, etc., and the above-mentioned pullulanase-like conjugated enzyme having the alpha-amylase activity at prescribed pH and prescribed temperature. As a result, glucose can be produced in good yield. Furthermore, since the pullulanase-like conjugated enzyme promotes saccharification reaction of starch, the glucose can usually be obtained in 0.5-3% higher final yield.

Title: Drain pipe
Inventor: YOSHIZAWA TADAO
IPC: F16L9/12
Filed: 1977-10-19
Abstract: PURPOSE: To prevent a drain pipe from being blocked by admixtures accumulated on its bottom, by forming arched flow limiting walls from the bottom toward the center of both pipe sides.  
     CONSTITUTION: Arched flow limiting walls 4 are solidly formed from the bottom 2 to almost the center of a drain pipe 1 so that the passage is gradually reduced toward the bottom 2. Since the walls 4 play a role of banks in the pipe, the water level 6 of drain 5 is elevated than that 6a incase of without the walls 4. As the flow resistance on the bottom against the running water is generally larger than that on both sides, it tends to be reduced when the contact with the bottom is reduced by the limiting walls. In addition the water level is elevated and accordingly the flow speed of drain is markedly increased, which carries away admixtures 7 in the drain without accumulation on the bottom 2.

Abstract: PURPOSE:To enable faithfully the readout of an image by increasing the capacity of charge storage means larger than the parasitic capacity of a switch, thereby improving the clearness and the reproducibility of the image to be read out. CONSTITUTION:A plurality of photoelectric converters for storing charge storage means C by photoreceiving, a plurality of switches S connected in series with one ends of the converters, and means for producing the storage amounts as signals as the means C stores charge are provided to sequentially conduct the switches C in a time series manner. In such a reader, the capacity C1 of the means C is increased larger than the parasitic capacity SC of the switch S. If the SC is increased in this case, a floating capacity FC is increased. When the switch S is closed, a current creeps to the capacitor C to reduce a current passing a load resistance R. Thus, as C1/SC increases, the relative output value increases, and if the C1/SC is increased, an influence of an irregularity cause to the output signal is reduced.
