Title: Fine crosslinked cellulose particle and its production
Inventor: MEIWA YOSHIHEI
IPC: C08L1/00
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To obtain fine crosslinked cellulose particles simply, easily and inexpensively without necessitating a large quantity of energy, depolymerization treatment, etc., even when a common pulverizer is used by crosslinking a cellulose fiber with a crosslinking agent and pulverizing the crosslinked cellulose into fine particles. SOLUTION: A cellulose fiber (one made of pulp) is crosslinked with a crosslinking agent (e.g. polycarboxylic acid), and the crosslinked cellulose fiber is pulverized to produce fine crosslinked cellulose particles having a mean particle diameter of 300μm or below. The means for pulverization may be a wet process or a dry process. Therefore, the fine particles can be recovered in a state of a powder or a paste. By controlling the degree of crosslinking of the fiber, a powder controlled in flow properties, thixotropy, thickening properties, dispersibility, etc., and showing reduced swelling and excellent dimensional stability even in a water-containing state can be obtained.

IPC: F24F1/00
Filed: 1990-05-17
Abstract: PURPOSE:To enable an air curtain zone to be easily formed, reduce a cost, facilitate an installing work and further perform a free air conditioning and purification in a zone by a method wherein a gas injection flow is injected by an injection flow generating means substantially in accurate opposition to a central part of a parasol-like guiding surface and the injection flow is passed along the guide surface. CONSTITUTION:As an operating panel 50 is operated to cause an axial air blower 2 to be operated, a vane wheel 22 is rotationally driven by a motor 23. Then, air outside a guiding member 1 enters a casing 21 at an air suction inlet 24 through a guard 26, is biased by the vane wheel 22 and then the air becomes an injection flow A directed toward a central part of a parasol-like guiding surface 1a of the guide member 1 and injected. The air strikes against the central part of the parasol-like guide surface 1a, is guided by a guide 28, becomes a flow B along the guide surface 1a and then is dispersed toward an outer circumferential edge 1c. Then, the air becomes a film-like annular injection flow C from an entire circumference of the outer circumferential edge 1c and flows out in a slant downward directed flow. Rotation of the guide member 1 is controlled through a motor 13 in such a way as an elongated part 11 of the guiding surface 1a is always followed toward an orientation of the sun detected by a solar sensor 15 by the control device 16, thereby an incident action of the solar beam into the zone 9 is prohibited, resulting in that an inner area of the zone 9 can be efficiently air conditioned.

IPC: H02P25/02
Filed: 1981-08-11
Abstract: A method for operating a frequency converter of the type having an auxiliary commutating device for commutation at speeds which are lower than a machine-related minimum speed of operation. In a first speed range which begins at speed zero, the thyristors of a three-phase bridge of the inverter are commutated cyclically, as customary, six times per revolution of the machine. In a second speed range which is adjacent to the first speed range and below the machine-related minimum speed of operation, only every second commutation is executed. In embodiments of the invention wherein there is provided a third speed range which is adjacent to the second speed range and extending up to the machine-related minimum speed, only every third commutation is executed. In this manner, an auxiliary commutating device having a predetermined frequency limit can be utilized at speeds corresponding to two or three times the speed at which such an auxiliary commutating device could be used in prior art systems. Only slight drops in mean torque are experienced with the inventive method.

IPC: H04L7/00
Filed: 1995-05-25
Abstract: PURPOSE: To automatically control delay time for data conversion into a synchronous transfer mode to an optimum value even in the fluctuation of transfer delay time for respective cells. CONSTITUTION: When data at the synchronous transfer mode(STM) is transmitted/received as cell data by the network of an asynchronous transfer mode(ATM) and it is converted into data of the asynchronous transfer mode at a prescribed period T on a reception-side, the reception-side measures/stores delay time Td and abolishes cell data when cell data B is received later against timing t for converting received cell data into data of the synchronous transfer mode. Timing for converting next cell data C and subsequent data is set to be time t5 obtained by shifting it from t4 by delay time T2 and therefore the fluctuation of transfer delay time for the respective cells is absorbed. The absorption processing is automatically executed, and it is automatically controlled to appropriate timing in accordance with the fluctuation of transfer delay time for the respective cells.
