Title: Automatically operated lathe and method for controlling the same
Inventor: SHINOHARA HIROSHI
IPC: B23B7/00
Filed: 1998-04-10
Granted: 1999-12-11
Abstract: A turret (24) is clamped to a tool post body (22) by a pair of coupling members (66, 68). Also, at the time of indexing rotation for tool selection, the tool post body (22) and the turret (24) are moved relative to each other in the Z-axis direction, whereby the pair of coupling members (66, 68) are disengaged to unclamp the turret (24). At this time, in synchronism with the relative movements of the tool post body (22) and the turret (24) in the Z-axis direction, the tool post body (22) is moved relative to a lathe base (10) in the Z-axis direction. Such movements of the tool post body (22) are adjusted in such a direction and in such an amount of movement as to eliminate relative movements between the turret (24) and a headstock (12). Such movement control stops movements of the turret (24) and a tool mounted thereon relative to the headstock (12) and a work, so that the problem of interference between these constituent components is eliminated.

Title: Self-balancing shielded bipolar air ionizer
Inventor: PARTRIDGE LESLIE W
IPC: H01T23/00
Filed: 1999-01-08
Granted: 2001-04-11
Abstract: An air ionizer comprises at least two electrodes contained within a recessed region of an insulating housing. When high voltages are applied to the electrodes, nearby air molecules are ionized and generally move towards a target region outside the housing. Because the insulating housing shields the electrodes, the production of ions is not significantly disturbed by charged or grounded objects other than those in the general direction of the target region. In one embodiment, the electrodes are piaced close enough to the inner walls of the recessed region that the portions of the surfaces of the walls near the electrodes are electrostatically charged. This charge tends to repel the nearby ions, expelling many from the recessed region towards the target region.

Title: Low bit-rate spatial coding method and system
Inventor: DOLBY RAY MILTON
IPC: G10L19/008
Filed: 1999-04-07
Granted: 2001-06-07
Abstract: A spatial audio coding system, including an encoder and a decoder, operates at very low bit-rates and is useful for audio via the Internet. The listener or listeners preferably are located within a predictable listening area, for example, users of a personal computer or television viewers. An encoder produces a composite audio-information signal representing the soundfield to be reproduced and a directional vector or ""steering control signal"". The composite audio-information signal has its frequency spectrum broken into a number of subbands, preferably commensurate with the critical bands of the human ear. The steering control signal has a component relating to the dominant direction of the soundfield in each of the subbands. Because the system is based on the premise that only sound from a single direction is heard at any instant, the decoder need not apply a signal to more than two sound transducers at any instant.

Title: Method for collection and identification of automatic dynamic testing subjects
Inventor: LIN YING-DA
IPC: G06F17/30
Filed: 1999-12-10
Granted: 2001-09-11
Abstract: The major problem of Internet subject database is that there are not enough subjects and subjects are not good enough. For taking care of both them, it needs more subject sources and mechanism for identifying good or bad subjects to decide if subjects are able to preserve in the database or not. This invention provides a method for collection and identification of automatic dynamic testing subjects that teachers and students are able to collect subjects to the database, and every unit is able to share subjects of each other in order to fast increase the database and expand the scale of usable database. The more self-acting students are, the more suitable the method is. For the method to identify the quality of a subject, we improve the traditional internal corresponding analysis method to immediately change the subject identification of the test sheet after a student finish the test instead of the traditional method that it needs all students to finish the test for identification. It is called dynamic added internal corresponding method.

Title: Radio signal environment analyzer
Inventor: KUWABARA YOSHIHIKO
IPC: H04W64/00
Filed: 1999-12-27
Granted: 2001-10-21
Abstract: The invention is a radio signal environment analyzer including a transmitter that transmits signal through antenna. Such signal utilizes one set of pseudo noise for biphase shift keying (BPSK) modulation. A receiver includes one set of array antenna to receive the transmitted signals of the transmitter. The outputs of antenna integrating the array antenna keep being selected. Each of those output signal is multiplied by the provided signal of PN code generator. The provided signal of PN code generator is consistent with the received signal sequence of transmitter but slightly different in transmission rate, so it is taken for reverse spread spectrum. The reverse spread spectrum signal is converted as baseband signal and the orthogonal detection is performed. The signal processing element display the time delay data, which stands for the power and delay time of the received signal. Furthermore, based upon the specified time interval of the received directional analysis, the direction to be reached can be calculated by the displayed results concerning power, delay and angle (PDA).
