Inventor: NAKAMURA YOUICHI
IPC: G06F13/12
Filed: 1991-04-12
Granted: 1996-10-29
Abstract: A computer system executing a reset method when an adaptor module is faulty comprises processor modules (1), adaptor modules (2), a  system bus (3) connecting the processor modules (1) and the adaptor modules (2), devices (4) and lines connected to the adaptor module (2).  When the adaptor module (2) is faulty and becomes a special status, this method comprises a step for issuing an instruction by which the processor module (1) resets the adaptor module (2); and another step in that when the processor module (1) detects the special status of the adaptor module (2), the adaptor module (2) starts to operate by various predetermined operations.  By using the above method, even when the adaptor module (2) has been in a non-operational status, the adaptor module (2) is initialized and the reset capable of restarting can be carried out.

Title: Automatic dental flossing device
Inventor: GAO YONG
IPC: A61C15/04
Filed: 1992-06-26
Granted: 2000-12-12
Abstract: The principal object of the present invention is to provide an effective, easy-to-use and power-driven device for optimizing and comforting the process of using a dental floss to clean teeth. In accordance with this invention, there is provided an automatic dental flossing device comprising an elongate housing handle with an extending thinner arm forked at its front end, in which a pair of removable reels with dental floss on them, a transmission gear system, an operating switch, a winding switch and a powered motor are installed. The handle is divided into three casings which are the upper, bottom and rear casings, respectively. The upper casing is openable for storing or changing the dental floss on the two reels. The gear system is mounted in the bottom casing. The motor is in the rear casing. A pair of guiding slots are grooved on the forked arm which has a pair of slotted conducting tube-like means on its two tines, for guiding the dental floss from the upper casing to the tines of the forked arm. The dental floss, stretched across the two tines of the forked arm, is guided into the handle and wound on the two reels one of which supplies fresh dental floss, another of which takes up the used one. The dental floss can be automatically reciprocated by pulling the operating switch means backward, or tightly held by pushing the same switch means forward. Tension of the dental floss is controllable. On the other hand, the dental floss can be wound continually in one direction, backward or forward, by using the winding switch means. The pair of removable reels carrying the dental floss are driven by the transmission gear system which comprises a primary gear with partially geared circumference, a belt, and two pinions installed on two separate shafts on which the two reels are also installed. The primary gear can be moved into three engaging positions to alternately drive the two pinions, or engage only one of them, so the dental floss will be manipulated in three different operating modes for reciprocating, supplying or rewinding the dental floss. The driving belt deliver power from the motor to the primary gear, having flexibility of slipping on the shafts to release any unexpected overload for protecting the device and user as well.

IPC: G01N29/04
Filed: 1993-06-01
Granted: 1998-02-03
Abstract: A method and apparatus for use in confirming hydrogen damage in a boiler tube comprises a pair of electromagnetic acoustic transducer coils which are mounted for movement toward and away from each other. An electromagnet produces pulses that generate acoustic beams across a chord and within the wall thickness of the boiler tube. For adapting to boiler tubes of different outside diameters, the transducers coils are mounted on a resilient member so that the coils can be pressed against the outer surface of coils having a variety of outside diameters. The angle of the acoustic beam between the coils must also be adjusted, however, and this is done by changing the frequency of energy applied to the coils.
