Title: Vertical screw conveyor and vertical transport device
Inventor: SUZUKI MOTOMITSU
IPC: B65G33/14
Filed: 1990-08-06
Abstract: PURPOSE:To transfer a predetermined quantity of material by a small drive force for a vertical screw conveyor for grains, etc., by rotating a cylindrical casing and a screw blade in the same direction at different speeds from each other's. CONSTITUTION:A movable cylindrical casing 4 and a screw blade 13 are rotated in the same direction at different rotation speed from each other's by rotary drive units 9, 15 respectively. Grains taken into the cylindrical casing 4 receives a large centrifugal force by rotation of both to be pressed to the inner wall surface of the cylindrical casing 4, and they are moved along the upper surface of the screw blade 13 by differential rotation number between both to be transferred. A predetermined quantity of the material can thus be transferred by a small drive force.

Title: Method for operating integrated circuit
Inventor: KELVIN EDWARD MACRAFF
IPC: G06F1/04
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To provide an integrated circuit 11 having a frequency detecting circuit which supplies one or more digital signals to a current source according to the detected operation frequency of a generated reference clock. SOLUTION: With a signal 50, the current source 26 can change the operation state among two on more discrete current output levels by a digital control system. The signal 50 is used to select and supply a high-current output level to an external oscillator circuit 16 by the current source in startup mode, thereby guaranteeing that the integrated circuit 11 can start up in an optimum shortened time period. After the startup operation is completed, the current source 26 can be switched to a low-current operation mode by making use of the signal 50 and then the influence of electromagnetic interference(EMI) is reduced in normal operation mode after the startup operation.

Abstract: PURPOSE:To remarkably decrease the amount of fluid leak between a revolving part and a stationary part by installing a restricting member on one side-part in the axial direction of a non-contact seal part in such a manner that the restricting member is integrated into one body with the revolving part. CONSTITUTION:A labyrinth packing 15 whose fluid passage is zigzag is formed by both projected parts 12, which are projected in a ring-shape from the peripheral surface 11a a revolving part 11, and throttle-pieces 14, which are projected in a ring-shape from the inner surface 13a of a stationary part 13. Flow restricting members 17 are made up of many blade-shape projected members installed on the peripheral surface of the revolving part 11, and their blade angles are determined so that the flow from a low pressure chamber side 18 to the labyrinth packing 15 side is produced. On the stationary part 13 situated on the downstream side of the flow (marked by an arrow mark A) produced by the restricting members 17, a plurality of fluid passages 19, which let the discharged fluid (steam) compressed by said flow run toward the suction side of the flow restricting members, are formed in the circumferential direction at a regular interval.

Title: Data processing system, host device, data processor, host device control method, data processor control method, and storage medium storing computer-readable program
Inventor: TSUKADA NOBUYUKI
IPC: G06F3/12
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To reduce the size of a memory of data processor and to reduce the material cost of a host device itself by requesting the data processor that has acquired the individual identification data in the host device to update the data and making the data processor rewrite the individual identification data stored in a nonvolatile memory in response to the request of the host device. SOLUTION: The host device 101 requests a printer 103 that is newly connected to a USB to return the report data including the individual identification data necessary for identifying the individuals. When a printer 102 having the data exactly the same as the returned individual identification data is already connected, an instruction is given to change the data into the individual identification data different from those of the printer 102. When it is decided that an answer is received from the printer 103 to show the end of changing the individual identification data, the new device driver setting data corresponding to the changed individual identification data are stored in a storage such as a hard disk.

Title: Power converting apparatus for automobile
Inventor: SATO YOSHIO
IPC: H02M3/155
Filed: 1995-08-16
Abstract: PROBLEM TO BE SOLVED: To eliminate a reactor of a step-up circuit by applying an output of a battery, when an engine stops, to a neutral point of an armature coil of a generator. SOLUTION: A generator 2 is provided in an engine. An output of this generator 2 is adequately boosted or dropped by a step-up/step-down circuit 8 and then adjusted to a constant voltage and is then applied to an inverter 5. In the inverter circuit 5, a DC voltage of the step-up/step-down circuit is converted into an AC power required for a load 6. Moreover, an output of the battery 3 is connected to the neutral point of the generator 2 via the battery drive switch 9. The battery drive switch 9 is controlled to be closed when the load 6 turns on while the engine 1 stops. In this case, since the power is supplied to the neutral point of the coil of the generator 2 from the battery 3 and is then boosted, the inductance of the armature coil of the generator can also operate as the reactor of the step-up 1 step-down circuit.  Thereby, a particular reactor for step-up/step-down circuit can no longer be required.
