Inventor: MIMURA HIDEKI
IPC: G11B27/34
Filed: 1996-04-19
Abstract: On décrit un système (31, 41, 32, 33) dans lequel un utilisateur modifie manuellement la qualité de périodes spécifiques d'une séquence vidéo (180) codée. Après le codage (50) automatique de cette séquence vidéo en un format numérique comprimé, une personne qui met en forme (31, 33) la séquence vidéo codée, réexamine la qualité de celle-ci et indique manuellement s'il faut modifier la qualité de périodes (180) spécifiques de cette séquence. Etant donné que le support d'information numérique, tel qu'un disque optique (84, 90), lequel mémorise la séquence vidéo codée, possède une capacité limitée de mémorisation, le nombre total de bits de la séquence vidéo (50) codée et la qualité de celle-ci sont limités. Un certain pourcentage de bits est enlevé de la séquence de temps et placé dans un groupe (368) de bits. Au moyen d'une fonction exponentielle (368), de nouveaux bits sont calculés et les bits placés dans le groupe sont distribués proportionnellement à des trames (376) vidéo, lesquelles doivent être ensuite vérifiées (394) et éventuellement réglées (398, 400), afin d'empêcher le sous-dépassement de capacité de la mémoire tampon vidéo.

Abstract: An on-axis through the lens optical alignment system for use in semiconductor manufacturing using step and scan photolithographic techniques. An optical alignment system uses a partially common path with the projection optics (16) optical axis (38) in order to detect alignment targets on a wafer (10) and a mask (20). The relative position of the mask (20) and wafer (10) is detected during a single simultaneous scan, and the mask (20) and wafer (10) are resultantly aligned. This provides advantages over prior art multiple channel off-axis through the lens alignment systems and single channel non-through the lens alignment systems. A detailed optical apparatus (60) is disclosed.

Title: Method for controlling the feed of backup rolls in a veneer lathe and a backup roll apparatus in a veneer lathe
Inventor: NAKAYA TAKASHI
IPC: B23Q15/02
Filed: 1997-04-21
Abstract: A method of controlling the feed of the backup rolls of a log backup apparatus for use in a veneer lathe for preventing a log from bowing while veneer is peeled from the log. The method comprises the step of centripetally feeding the backup rolls from a control-start diameter .PHI. at a provisional feed rate f which is higher than a predetermined feed rate F by a feed rate of a preselected correction value a per log rotation. The aforementioned control-start diameter .PHI. is slightly larger than the diameter of the log at which the backup rolls are brought into contact with the log. The method further comprises the steps of stopping the centripetal feeding of the backup rolls at the provisional feed rate f when the bowing is eliminated from the log and thereafter centripetally feeding the backup rolls at the predetermined feed rate F, thereby eliminating the bowing that occurs during the veneer peeling from the log.

Abstract: A system and process to administer an incentive award program through the use of a zero-limit credit instrument. The present invention allows incentive program Participants to take advantage of any incentive program earnings as a pre-payment to their card accounts.  There is therefore no up-front credit liability for either the participant, or the incentive program administrator.  The Participants in the incentive program are issued (120-126) a credit card account with a zero credit limit.  Upon the rewarding of earnings (70) in the incentive program, a monetary payment is issued (72) to the Participant's credit card account.  While the account's credit limit remains at zero, purchases (164) may be made by authorizing purchase transactions against an outstanding positive balance on the account.  Such authorization then temporarily lowers the outstanding balance until settlement and posting of the purchase transaction into the Participant's account, which then permanently downgrades the outstanding balance.  This purchase transaction is effectively paid for by the pre-paid positive balance created (72) in the Participant's account by the incentive program administrator.

Abstract: Using a mask opening a gate region, an undoped GaAs layer is selectively etched with respect to an undoped Al0.2Ga0.8As layer by dry etching with introducing a mixture gas of a chloride gas containing only chlorine and a fluoride gas containing only fluorine (e.g. BCl3 + SF6 or so forth).  By about 100% over-etching is performed for the undoped GaAs layer, etching (side etching) propagates in transverse direction of the undoped GaAs layer.  With using the mask, a gate electrode of WSi is formed.  Thus, a gap in a width of about 20 nm is formed by etching in the transverse direction on the drain side of the gate electrode.  By this, a hetero junction FET having reduced fluctuation of characteristics of an FET, such as a threshold value, lower a rising voltage and higher breakdown characteristics.

Title: Method and apparatus for improving error path control in a feed-forward amplifier
Inventor: VAN HORN MARK IAN
IPC: H03F1/32
Filed: 1997-02-13
Abstract: A feed-forward amplifier (200) bases control of an error path (123) within the feed-forward amplifier (200) on an output signal after performing carrier cancellation to remove the carrier signal. The feed-forward amplifier (200) implements couplers (203, 212), a carrier cancellation gain/phase control block (206) and a carrier cancellation delay block (209) to cancel the carrier signal. By basing the control of the error path on a signal without the carrier signal, control of the error path (123) does not suffer from the effects of high dynamic range presented by the carrier signal, thus improving overall control of the feed-forward amplifier (200).

Title: Hydrodynamically lubricated rotary shaft seal with environmental side groove
Inventor: KALSI MANMOHAN S
IPC: F16J15/32
Filed: 1997-06-04
Abstract: The present invention is a hydrodynamically lubricated interference type rotary shaft seal suitable for environmental exclusion and high pressure lubricant retention which incorporates an environment-side groove to control and minimize interfacial contact pressure at the dynamic sealing interface, which permits optimum hydrodynamic film thickness, thereby significantly lowering the self generated heat produced by the seal, as compared to the prior art. The cool-running nature of the present invention permits the use of higher modulus seal materials and higher surface speeds, compared to the prior art, and allows the seal to operate in applications with relatively poor heat dissipation. The controlled interfacial contact pressure of the present invention also permits effective hydrodynamic lubrication with lower viscosity lubricants, including water.
