Inventor: NANKOU YOSHIAKI
IPC: B62J23/00
Filed: 1998-11-27
Granted: 2003-06-11
Abstract: A protective plate for attachment to a bicycle frame for guiding a chain includes a plate body having a first side for facing laterally toward the bicycle frame, a second side for facing laterally away from the bicycle frame, a lower portion, and an upper portion. The lower portion of the first side of the plate body is structured to align with a bottom bracket of the bicycle, and a positioning abutment member is disposed on the upper portion of the first side of the support body. An upper surface of the positioning abutment member forms a positioning abutment for positioning a front derailleur to the bicycle frame. Additionally, a chain guiding abutment may be formed on the upper portion of the second side of the support body for guiding the chain as the chain shifts from a larger chainring to a smaller chainring.

Title: Data process method, recording medium and data processor
Inventor: MORIYAMA KOICHI
IPC: G06F9/46
Filed: 1999-02-24
Granted: 2001-03-01
Abstract: When using future to perform message passing, even if the object is in a standby status due to any problem, the object can be recovered from the standby status without having to use timeout. When a client sends a message to a server object, the data field is ensured. Therefore, the processed data will be stored in the data field if the process of the server object is completed normally. If the processed is not completed normally, the status data indicating the status of the server object will be stored in the data field. Consequently, by reading the stored data in the data field, the client object can accept the processed data if the process of the server object is completed normally or will accept the status data otherwise.

Title: A stabilizer composition comprising a latent mercaptan, a polymer composition comprising the same and a method for preparing the polymer composition
Inventor: DUVALL TOD CHARLES
IPC: C08K5/37
Filed: 1999-03-22
Granted: 2001-10-01
Abstract: Flexible, semi-rigid, and rigid vinyl chloride polymer compositions comprising a latent mercaptan-containing heat stabilizer are substantially free from the offensive odor typically associated with mercaptans and are protected during processing by the degradation products of the latent (i.e., blocked) mercaptan which include a free mercaptan. the free mercaptan thus released enhances the activity of metallic-based heat stabilizers such as zinc carboxylates and organotin carboxylates and mercaptides in the polymer composition. Other products of the degradation are believed to include carbocations of the blocking moiety which are stabilized by a molecular structure in which the electron deficiency is shared by several groups. The latent mercaptan is selected from the group consisting of a 2-S-(tetrahydropyranyl)-thioglycolic acid, and an ester thereof.

Then, the chemical mechanical polishing (CMP) process is used to polish and strip the covered dielectric layer and conduction layer above the protection layer surface. The dielectric layer in the dual metal damascene opening is removed to expose the conduction layer that is used to fabricate the lower electrode. A capacitance dielectric layer is formed on the conduction layer. Another conduction layer used to fabricate the upper electrode is formed and its pattern is defined so as to complete the fabrication of capacitor.

Title: Fan checking method and device thereof
Inventor: SHIE SHIN-MAU
IPC: G01R31/34
Filed: 2000-03-14
Granted: 2003-03-01
Abstract: The present invention relates to a fan checking method and a device thereof. A fan to be checked is placed on the check space of the checking device that is equipped with a power box for providing fan operating power, a power socket base board, and a data recorder for recording related operating data of the fan. Then, together with the fan on the checking device, the checking device is placed on a conveyer belt to repeatedly pass through various environments of different temperatures (such as high temperature and room temperature) in various operating ways (by simulating operations in the system). Finally, a computer is applied to read related operating data of the fan before determining when and under what condition the fan is defective. Since a checking device can check several fans at the same time and several checking devices can be placed on a conveyer belt simultaneously, not only high checking efficiency and simple operation can be accomplished but also one hundred percent quality and reliability of the checked fans can be ensured.
Patent TW-536692-B (TW)
Title: Using gain-adaptive quantization and non-uniform symbol lengths for improved audio coding
Inventor: DAVIDSON GRANT ALLEN
IPC: G10L19/032
Filed: 2000-04-11
Granted: 2003-06-11
Abstract: Techniques like Huffman coding can be used to represent digital audio signal components more efficiently using non-uniform length symbols than can be represented by other coding techniques using uniform length symbols. Unfortunately, the coding efficiency that can be achieved by Huffman coding depends on the probability density function of the information to be coded and the Huffman coding process itself requires considerable processing and memory resources. A coding process that uses gain-adaptive quantization according to the present invention can realize the advantage of using non-uniform length symbols while overcoming the shortcomings of Huffman coding. In gain-adaptive quantization, the magnitudes of signal components to be encoded are compared to one or more thresholds and placed into classes according to the results of the comparison. The magnitudes of the components placed into one of the classes are modified according to a gain factor that is related to the threshold used to classify the components. Preferably, the gain factor may be expressed as a function of only the threshold value. Gain-adaptive quantization may be used to encode frequency subband signals in split-band audio coding systems. Additional features including cascaded gain-adaptive quantization, intra-frame coding, split-interval and non-overloading quantizers are disclosed.

Abstract: A method for driving a head includes the steps of: determining a head-present-position by a head-position-data supplied from a head-position-detector; calculating in advance a target-sector accessible-time by the head for a first time based on a data of a head-present-position, a location data of a target sector at a destination and a driving capability of a head assembly and controlling a head-assembly-driver by determining a moving speed and an acceleration/deceleration pattern of the head for completing a seek to a track including the target sector within the accessible-time. The method is useful for controlling the head of a disc driving apparatus, especially a magnetic head of a magnetic disc driving apparatus, and the method reduces power consumption at a seek-operation without extending an access time.

In a first exemplary embodiment, the remote station combines the multipath components of the reverse link busy bits from each of the transmitting base stations in its Active Set and in response transmits a reverse link signal only when all of the reverse link busy bits indicate that the base stations in the remote stations Active Set have reverse link capacity. In a first alternative embodiment, the remote station weights the reverse link busy signals in accordance with the signal strength of the base station transmitting the busy signal and determines whether to transmit based on the weighted sum of the busy signals. In a second alternative embodiment, the remote station weights the reverse link busy signals in accordance with the signal strength of the base station transmitting the busy signal and determines a maximum reverse link data rate based on the weighted sum of the busy signals.
