The present invention provides novel glycopeptides antibiotic derivatives comprising a sugar residue (I) represented by the formula: (wherein n is an integer of 1 to 5: Sugs are each independently a monosaccharide, (Sug)n is a divalent sugar residue formed by binding of same or different 1 to 5 monosaccharides; RA1 is optionally substituted lower alkyl, optionally substituted lower alkenyl, or optionally substituted cycloalkyl; and RE is OH or NHAc (Ac is acetyl)) is bound to an aromatic ring of the fourth amino acid residue in the glycopeptide skeleton. These derivatives have antibacterial activity against vancomycin-resistant bacteria.

A tensioner for a chain or similar power transmission medium comprises a spring-biased plunger having annular rack teeth with gradually sloping forward surfaces and steeper rearward surfaces. The teeth are engaged by radially movable balls received in inclined grooves in an axially movable annular ball seat disposed in an annular groove formed in the wall of a plunger-accommodating hole in a tensioner housing. The bottoms of the inclined grooves face a steep rearward surface of a rack tooth, and the annular ball seat is axially movable in the annular groove and biased in the plunger protruding direction by a spring that exerts a biasing force greater than the biasing force exerted on the plunger. The balls and the movable annular ball seat block retraction of the plunger on engine start-up, but permit retraction when excessive force is imparted to the plunger while the plunger is in a protruding condition.

According to one embodiment, a broadcast transmitter includes a generator and a transmitter. The generator generates service information including event information table information that describes format information indicating the format of distribution content corresponding to broadcast content distributed via a communication network. The transmitter multiplexes the service information into a transport stream and transmits the transport stream.

The present invention provides a sol of spinous silica-based particles in which silica-based particles having peculiar forms, spinous forms are dispersed in a solvent. The spinous silica-based particles have verrucous projections formed on surfaces of spherical silica-based particles. In the spinous particles, a value of the surface roughness (SA1/SA2, SA1 indicating a specific surface area measured by the BET method or the Sears method and SA2 indicating a specific surface area converted from an average particle diameter (D2) measured by the image analysis method) is in the range from 1.7 to 10. Furthermore the average diameter (D2) measured by the image analysis method is in the range from 7 to 150 nm.

The check valve unit of a hydraulic tensioner comprises a check ball, a ball guide and a disc-shaped retainer. The retainer is fixed to the high pressure oil chamber side of the ball guide by crimping an annular portion of the ball guide over the outer edge of the retainer so that substantially all of an annular circumferential portion of the high pressure chamber side of the retainer is held underneath the crimped portion of the ball guide. The crimped portion of the ball guide forms a recess for receiving and positioning a plunger-biasing spring. A ball seat is similarly secured to the inflow side of the ball guide by crimping.

A damper device includes a drive plate; a driven plate; and a torque transmission mechanism having different types of damper springs. The torque transmission mechanism transmits torque of the drive plate to the driven plate via at least one of the damper springs, wherein the torque transmission mechanism is structured to allow a combination of damper springs acting during torque transmission to be changed at lease three times as a rotation angle of the drive plate relative to the driven plate becomes greater. Each of the damper springs can be extended and compressed circumferentially about the rotation axis and is disposed at the same radial position about the rotation axis.

In a plastic hydraulic tensioner having an oil reservoir formed as a recess in a portion of a synthetic resin tensioner body adapted to engage a tensioner mounting surface on an engine block, metal bushings are insert-molded in the synthetic resin tensioner body for receiving mounting bolts by which the tensioner is secured to an engine block. The outer circumferential surface of each bushing is provided with at least one flat portion or at least one concave groove, and a protruding portion of the bushing is formed adjacent the end of the flat or groove remote from the engine block-contacting end of the bushing.

It relates to a hybrid recording apparatus using. The recording apparatus includes a magnetic disk medium for recording and reading data by a magnetic head, a nonvolatile memory in which a write cache area is allocated, a cache control unit for temporarily loading write data, which is recorded on the magnetic disk medium, into the write cache area in accordance with a write request from a higher-level apparatus. A memory allocation management unit stores memory management information in the magnetic disk medium for management thereof, the memory management information representing an allocated position of the write cache area in the nonvolatile memory.
