Title: Reading method of screw rotation angle of hand-held impact wrench, hand-vibration detection method, tightening evaluation method and control method of hand-held power screw loosening tool
Inventor: YAMADA MASAKAZU
IPC: B25B23/145
Filed: 2000-03-15
Granted: 2001-01-21
Abstract: A detecting means which detects the rotation angle in the right and left rotation directions of a rotation member is provided on a hand-held power screw tightening tool. When a screw is tightened, if there is rebound, the total of the rotation angles in the left rotation direction is deducted from the total of the rotation angles in the right rotation direction to obtain a whole rotation angle (P). A rotation angle during deceleration when impact is applied is denoted as DELTA H and totaled. Then a hand-vibration angle is calculated by a formula; Hand vibration angle = Total of (P - Pd) - Total of DELTA H (wherein Pd denotes the predetermined designed impact angle of an impact wrench and expresses an angle corresponding to 360 DEG/m when m times of impacts are generated while the rotation member makes one turn). When the total of the rotation angle DELTA H during deceleration when impact is applied reaches the designed impact angle (Pd), the rotation of the rotation member is discontinued. When a screw is loosened, the rotation member is turned in an opposite direction and, in the same way, when a predetermined rotation speed in the loosening direction is reached, the rotation of the rotation member is discontinued.

Granted: 2003-03-21
Abstract: On receiving a link channel assignment request or a link channel reassignment request from a mobile station, a wireless base station specifies a unique word (UW) that is not assigned to any other mobile stations, and sends a channel assignment notification containing the specified UW to the requesting mobile station. The base station also sends the specified UW to its user processing unit, which extracts a signal sent from the requesting mobile station and generates a signal to be sent to this mobile station. The base station then defines a reference signal based on the sent UW, and adjusts each weight vector by using the defined reference signal and a signal estimated to have been sent from the requesting mobile station, thereby directing the directivity pattern to the requesting mobile station.

Title: Backlight including external electrode fluorescent lamp and method for driving the same
Inventor: CHO GUANG-SUP
IPC: H05B41/36
Filed: 2001-03-22
Granted: 2006-10-01
Abstract: The present invention discloses a backlight including external electrode fluorescent lamps and a method for driving the backlight. The backlight includes fluorescent lamps having external electrodes made of an electrically conductive material for wrapping outer peripheral surfaces including edge cross-sections on both ends of a glass tube with a layer of fluorescent substance applied thereon. The backlight is constructed in a manner that a plurality of such fluorescent lamps are installed at outer portions of a plastic light guide; that an alternating current type power source is applied from the outside to the fluorescent lamps by installing a plurality of the fluorescent lamps between a reflecting plate and a diffusing plate and electrically connecting them with one another; or that the fluorescent lamps are installed at a predetermined interval between upper and lower substrates with a layer of fluorescent substance applied thereon and spaced from each other, and electrodes to which an alternating current type power source is applied from outside are formed on opposite outer or inner faces of the assembled upper and lower substrates. According to the present invention, since the electrodes of the fluorescent lamps are formed at external portions and are repeatedly disposed, the fluorescent lamps can be interconnected in parallel to and driven by a single power source. Further, since the fluorescent lamps serve as a partition and simultaneously emit light by themselves, their uniform luminance can be maintained and thinner backlight can be obtained. The backlight of the present invention is driven by a square wave from a switching inverter, and is characterized by the use of an overshooting waveform and a self-discharge effect favorable to an initial discharge, thereby driving it by a low frequency of several dozen kHz and thus realizing high luminance and high efficiency.

Title: Injection unit and method for the controlled advancing and pressing of an injection nozzle
Inventor: CHROMY FRANZ
IPC: B29C45/17
Filed: 2001-05-03
Granted: 2002-09-21
Abstract: The invention relates to a novel method and a corresponding novel device for advancing and pressing an injection nozzle (4) against a mold (3) of an injection molding machine. To this end, two independently controllable drives are provided for advancing the injection unit (7) and for pressing the injection nozzle. Due to the drive-wise separation of the unit displacement and of the pressing, the invention enables the use of optimally adapted and, above all, economical driving means. The unit displacement is affected by a direct-action linear drive, for example, a simple pneumatic cylinder (9) with a relatively long travel and low expenditure of force. Alternatively, large-surface cylinders (50), (50'), which can be connected via couplings (clutches), are used for pressing. As a result, a displacing movement with a large build-up of force with the smallest possible expenditure of energy can be executed by corresponding multiplications on the micro scale.
