Title: Amylase inhibition-active substance and its use
Inventor: MURATA TATSUO
IPC: A61K36/73
Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To obtain the subject substance with high affinity for starch, and to provide a use of the substance. SOLUTION: This substance is obtained by subjecting any plant served as daily food (e.g. beans, potatoes or potato-like vegetables, teas, crude drugs) to extraction with water, an organic solvent or a mixture thereof. This substance, because of having high affinity for starch, exhibits α-amylase inhibitory activity through binding to starch; by regulating its amount to be added, the amount of the degradation and the rate of degradation of starch can be regulated. This substance is used in food and feed, or as a medicament, being useful for diet and in treating diabetics.

Title: Electrophotographic method
Inventor: KOJIMA SHIGETO
IPC: G03G5/147
Filed: 1989-09-07
Abstract: PURPOSE:To maintain the high-image quality stable over a long period of time by supplying an antioxidant to the surface of the electrophotographic sensitive body from the contact member with this photosensitive body. CONSTITUTION:The antioxidant is supplied to the surface of the electrophotographic sensitive body 2 from the contact member 17 of this photosensitive body 2. Namely, the molding 18 of the substance to be supplied to the surface of the photosensitive body 2 is supplied via a brush structural body 17 to the photosensitive body 2. The antioxidant to be used is largely classified to the antioxidant of a phenolic system (phenolic compd.), the antioxidant of a sulfur system (sulfur compd.), and the antioxidant of a phosphorus system (phosphorus compd.). The antioxidants of the phenolic system and the phosphorus system are relatively high in effect. The environmental resistance and image quality good over a long period of time are maintained in this way without allowing the surface of the photosensitive body to be deteriorated by the ozone by corona discharge and various kinds of ions even if the photosensitive body is repetitively used in a copying process.

Title: Pressure plate and editing device
Inventor: YAMAMOTO SUGURU
IPC: G03B27/62
Filed: 1990-09-03
Abstract: PURPOSE:To erect a support member to support a device main body by fitting the support member which supports the device main body to part of an outer casing body so that it can be stored and stood. CONSTITUTION:When this editing device is mounted on a desk, etc., the support member 2b is slid to outside a cut part 2c, and then rotated downward and erected. Further, when this device is used as the original pressure plate of a copying machine, etc., the support member 2b is fitted in the cut part 2c of the outer casing part 2 again and used. This original pressure plate does not come into contact with a platen surface directly, so the original pressure plate is prevented from becoming dirty or flawing. Further, the support member 2b can be molded in the same shape, so the production cost is reducible.

Title: Current amplification factor compensation circuit and charging/discharging circuit
Inventor: HIRAO YOSHICHIKA
IPC: H03F1/34
Filed: 1994-09-27
Abstract: PURPOSE: To make a current of a charging/discharging circuit stable. CONSTITUTION: An input to a transistor(TR) T21 included in a differential pair 12 is decided based on a resistor R1 and a constant current IC24 . On the other hand, an input to a TR T22 is decided based on a resistor R2. An output from the differential pair 12 is fed back negatively to the differential pair 12 by a feedback amplifier circuit 18. A factor (R1/R2) is multiplied with the constant current IC24 to obtain a very small current. The very small current is multiplied with β at a current amplification TR T23 and the amplified current is outputted as a compensated current via a mirror circuit 16. The compensated current is given to a charging/discharging circuit whose TR base current is a charging/discharging current. That is, the compensated current is given as a collector current of the TR of the circuit.  Then a current amplification factor, that is, the β is cancelled out.

Title: Method for controlling pressurization by servo motor and device therefor
Inventor: KATO TETSURO
IPC: G05D15/01
Filed: 1997-08-13
Abstract: PROBLEM TO BE SOLVED: To prevent the oscillation or delay of a pressurizing force on others by a mobile object driven by a servo motor, and to prevent the generation of shortages of the pressurizing force. SOLUTION: A pressurizing force Td is estimated by an observer. A gain A is multiplied by a value obtained by subtracting an estimated pressurizing force Td from a command pressurizing force Fc. A value obtained by multiplying a speed feedback by a gain Kv is subtracted from this multiplied value, so that a torque command Tc is obtained. A servo motor 2 is driven controlled by this torque command Tc. The feedback control of the pressurizing force can be attained, and quick response and exact pressurizing force control can be realized. Thus, the feedback control of the pressurizing force, in which the generation of the oscillation of the pressurizing force is prevented, is attained by adjusting the gains A and Kv.

Title: High frequency heating device
Inventor: KASHIMOTO TAKASHI
IPC: H05B6/68
Filed: 1989-09-07
Abstract: PURPOSE:To carry out defreezing of food with a simple configuration without failure by a method wherein a control means for use in adjusting a heating and defreezing time is provided to operate in response to a variation of a signal to be detected by an antenna arranged within a heating chamber, in particular, a variation in amplitude after sensing of a minimum point. CONSTITUTION:When a food 1 is placed at a central part of a turn table 12 within a heating chamber 2 and defreezed, a signal of a turning means is varied with a certain amplitude as indicated by a dotted line in a period. As a food temperature reaches about -2 deg.C, a turned voltage VS and an amplitude of the tuning means 8 are rapidly decreased. This is due to the fact that as a part of the food 1 reaches its icing point, a loss of an induction member is increased and a high frequency wave is accommodated at that part to reduce a high frequency wave detected by a tuning means 8 to each other. A magnetron 3 may heat the food 1 under a maximum electrical power until the tuned voltage VS is a minimum value at the time T1 and subsequently, a driving means 10 is controlled for its ON/OFF at a proper time interval by a control means 11 and then the defreezing operation is carried out. A time required for performing the defreezing operation is about 1.5 times in response to an elapsing time T1 up to the minimum value and at a time subsequent to the minimum value T1, a signal transmittance of the magnetron 3 is intermittently operated to prevent a boiling of the food 1 being cooked.
