Title: Concentration and purification of beta-amylase
Inventor: TANIGUCHI HITOSHI
IPC: C12N9/26
Filed: 1980-02-09
Abstract: PURPOSE: To carry out the concentration and purification of β-amylase in high efficiency, by adding a salt of a specific metal and a halogen-free anion to a β-amylase extract liquid, and concentrating the mixture through a membrane.  
     CONSTITUTION: A raw material such as soybean, malt, sweet potato, etc. is extracted with water or a buffer solution to obtain the extract containing β-amylase. Proteins are removed from the extract by acid precipitation, salting out at a relatively low degree of saturation, addition of an alkaline earth metal, etc. The extract is mixed with ≥0.01% of a salt of a metal selected from Ca, Mg and Al and a halogen-free anion, e.g. CaSO 4 , magnesium acetate, aluminum borate, etc., adjusted to pH4W6, and concentrated with a membrane, e.g. by ultrafiltration, reverse osmosis, etc. at 50W55°C. By this process, the putrefaction of β-amylase is prevented while keeping the high enzymatic activity.

Title: Projection type display device
Inventor: MATSUO MASATAKE
IPC: G02F1/135
Filed: 1989-01-25
Abstract: PURPOSE:To enhance graduation display ability and to improve the quality of a video by arranging filter whose absorbance distribution of a peripheral part is different from thant of a central part in at the least one optical path, among those of transmission type light valves for R, G and B. CONSTITUTION:In a projective display device including three transmission type light valves 4 for R, G and B, the filter 8 is provided in the optical path of the transmission type light valve for R. The absorbance of the filter 8 distributes highly in the peripheral part and low in the central part. Therefore, the intensity distribution of light made incident on the transmission type light valve for R varies and becomes almost the same as the intensity distribution of light incident on the transmission type light valve for B. Thereby, the in-plane brightness correction for R can be operated in common with that for B, and moreover the brightness distribution of outgoing light can be uniformized. Therefore, the gradation display ability of the transmission type light valve for R is enhanced and the quality of a video is improved.

Title: Digital pll circuit
Inventor: NOGAWA HIROMICHI
IPC: H03L7/06
Filed: 1992-01-31
Abstract: PURPOSE:To eliminate jitter in a clock in the steady-state, to extend the locking range only with a revision of a phase difference comparison discrimination circuit and a decode circuit and to limit the included jitter to a range being + or -1/2 of the clock signal. CONSTITUTION:A phase difference comparing discrimination circuit 104 obtains a phase difference between a Q output of a D flip-flop group 102 and an edge detection signal. A decode circuit 103 decides a D input of the D flip-flop to adjust the phase based on the Q output of the D flip-flop group 102 and a phase difference comparison signal. The digital PLL is established by decoding the Q output of the D flip-flop group 102 so as to be at a required timing. In this case, a timing adjustment signal generated by an edge detection circuit 101 is used to eliminate jitter in the steady-state by using one output after the edge is detected and taking into account a discrimination timing and the included jitter is limited to a + or -1/2 range of the clock signal.

Title: Voltage feedback circuit and constant voltage circuit using the voltage feedback circuit
Inventor: KAWATOKO OSAMU
IPC: G05F1/56
Filed: 1991-01-16
Abstract: PURPOSE:To reduce the occupation area of an IC and to reduce power consumption. CONSTITUTION:A differential amplifier 11 outputs a signal corresponding to a difference between a reference voltage Vr and a feedback voltage Vf fed back from a voltage feedback circuit 13. A transistor(TR) 14 for driving a load 31 is controlled for its conduction by an output signal from the amplifier 11. A current supplied from the TR 14 is converted into voltage by the circuit 13 and fed back to the amplifier 11. The circuit 13 is constituted of a switched capacitor circuit. Since the equivalent resistor of the switched capacitor circuit can be set up to an extremely high value by the frequency bands of clock signals C1 to C3, power consumption in the part can be suppressed. An output voltage V0 becomes a constant value determined by the capacitor values CA, CB of the switched capacitor circuit and the reference voltage Vr.

Title: Aqueous print lamination adhesive composition and method of print lamination
Inventor: IKEDA YASURO
IPC: B32B29/00
Filed: 1993-02-03
Abstract: PURPOSE:To obtain a composition which can exhibit excellent adhesiveness and water and oil resistances without causing the discoloration of printing ink and the yellowing of coated paper by mixing a specified water-dispersible polyurethane resin with a water-dispersible polyisocyanate compound. CONSTITUTION:The composition comprises a water-dispersible polyurethane resin having at least two isocyanate-reactive functional groups and a water- dispersible polyisocyanate compound. A water-dispersible polyurethane resin having a linear structure is generally desirable for this purpose because it is excellent in ordinary state bonding after crosslinking and durability as well as initial tack to substrates such as film. Functional groups reactive with the isocyanate groups of the water-dispersible polyurethane resin, such as hydroxyl groups, carboxyl groups or a combination thereof, are disirable from the viewpoints of especially odors and sanitary properties.

Abstract: PURPOSE:To prevent an electrolytic capacitor from disconnecting and to obtain the capacitor having a long life by generating polyurethane by reacting glycol with di-isocyanate in an electrolyte, adding, as required, a foaming agent to foam it, and securing a capacitor element. CONSTITUTION:An electrorolyte which contains, as a main solvent, glycol of ethylene glycol or the like and, as solute, boric acid or the like is first impregnated. Then, this capacitor element is contained in a case made of metal, such as aluminum or the like, di-isocyanate and foaming agent are poured therein to generate polyurethane. As the di-isocyanate, di-isocyanate hexane or the like is employed. As the foaming agent, a surface active agent is employed, and the density of the polyurethane is varied by regulating the contents. After the polyurethane is formed, it is closed with a cover. The adhesive properties of the generated polyurethane and the capacitor element are improved, and the vibration resistance of the element is improved. If the polyurethane is foamed, air gap in the case is increased, gas containing capacity is increased, thereby improving its life against its deterioration due to gas pressure.

Title: Portable electronic machinery
Inventor: NAKAMURA KOICHIRO
IPC: H05K1/02
Filed: 1989-01-27
Abstract: PURPOSE:To enhance the strength against deformation by setting the bending neutral surface of a substrate to a position where stress is hardly applied to an electronic paper by mutually differentiating the shearing elastic moduli of the fixing medium layers formed to both surfaces of the substrate. CONSTITUTION:The shearing elastic moduli of fixing medium layers 11, 13 fixing an outer plate 6 and a spacer 7 to the upper surface 4a of a substrate 4 and the bottom surface 4b thereof are differentiated and the bending neutral surface H2 of the substrate 4 is set to the position separated by a distance D2 from the bottom surface 1a of an electronic part 1. Since the stress applied to the bottom surface 1a of the electronic part 1 is smaller as the distance from the bottom surface 1a of the electronic part 1 to the bending neutral surface of the substrate becomes shorter, the breakage of the electronic part 1 is prevented. The thickness center of the electronic part 1 is most desirable as the position of the neutral surface H2. In order to reduce the stress to the electronic part 1 due to bending movement A, the shearing elastic modulus of the fixing medium layer 11 may be lowered with respect to the other fixing medium layer 13. Therefore, the fixing medium layer 11 may be constituted by partially applying a fixing medium 15 and, in a thickness differentiating method, the fixing medium layer 11 may be made thicker than the other fixing medium layer 13.
