Title: Production of xylooligosaccharide
Inventor: KISHIMOTO MAKIO
IPC: C12P19/14
Filed: 1987-08-31
Abstract: PURPOSE:To obtain a xylooligosaccharide in high efficiency, effectively utilizing enzymatic action, by preparing a xylan-containing liquid by solubilizing a vegetable extract, treating the liquid with an adsorbent and hydrolyzing the product with an enzyme. CONSTITUTION:A xylan-containing extract liquid extracted from a vegetable and solubilized by conventional method is treated with an adsorbent and hydrolyzed with an enzyme to obtain a xylooligosaccharide. The adsorbent is activated carbon, a clay mineral (e.g. acid clay or bentonite), a diatomaceous earth, an oxide or hydroxide of an element such as aluminum, silicon or titanium, a porous synthetic adsorbent, an ion exchange polymer, etc. The inhibition of the enzymatic action can be suppressed by removing pitch, etc., composed mainly of various polyphenols, rosin acid, etc., from the extraction liquid with the adsorbent.

Title: Semiconductor device
Inventor: FUKUSHIMA TOSHITAKA
IPC: H01L27/07
Filed: 1985-10-03
Abstract: PURPOSE:To increase the margin of a low level output of a logic circuit and to improve the switching speed by constituting a clamp circuit inserted between a collector and a base by a Schottky diode and a series resistor and constituting a collector resistor by series resistors so as to attain resistance division. CONSTITUTION:In order to clamp a collector voltage properly, a clamp circuit comprising the Schottky diode SBD and a resistor R3 connected in series therewith is inserted between a base and a collector. In inserting the circuit, the resistance value is set to obtain an optimum combination among the resistor R3 and the collector resistors R1, R2. Thus, the leading potential from a low level of a collector output is lowered and also an effective collector resistance viewed from the output side is decreased. As a result, the margin of an L level output VOL is increased remarkably. In this case, since the collector potential is clamped, the delay in the switching speed due to the saturated transistor is suppressed at the same time.

Title: Method for determining water resistance performance of screw conveyor
Inventor: YOSHINO KOJI
IPC: E21D9/12
Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To quantitatively, determine the performance of a screw conveyor regarding water resistance. SOLUTION: A screw conveyor 22, attached to an earth pressure type shield and transferring muck in a cutter chamber at the front end of the shield toward the back of the shield while consolidating the same, has its water resistance performance determined by use of a determining formula. The apparent unit volume weight γt of the muck, the coefficient of friction μ between the muck and iron, the inclination angle θ of the rotation axis of a screw, the hydraulic pressure drop ΔPwp in a plug zone 54, and the length Lp of the plug zone 54 are substituted into the determining formula: γt (μcosθ+sinθ)-ΔPwp/Lp.  The values in the determining formula are thereby determined, and if the values determined are positive, the water resistance performance of the screw conveyor 22 is determined to be sufficient, whereas if the values are negative, it is determined to be insufficient. Therefore, the water resistance performance of the screw conveyor 22 can be determined quantitatively.
