To analyze glycans and peptide sequences without liberating glycans from glycosylated peptides, a glycan structure is analyzed through negative-ion CID, in which sialic acid and fucose are resistant to elimination, and a peptide sequence is analyzed through positive-ion ECD.

A capsule in which an unstable active ingredient has been stabilized is obtained by lowering the moisture content of a solid preparation (granules, subtilis, tablets, etc.) containing a chemical unstable to moisture such as an imidazole PPI compound by drying or the like, and then filling in a capsule comprising a water-soluble polysaccharide such as pullulan as the main component or a PEG-containing gelatin capsule. For the further stabilization, the capsule per se may be dried. The capsule preparation thus obtained is a stable capsule preparation with the use of a capsule being stable at a low moisture content which contains a chemical unstable to moisture such as an imidazole compound.
摘要:
A closing phase that produces the smallest energization flux error at a connection input point is calculated based upon a residual flux of the first closing phase and the preliminarily given pre-arc characteristic and closing time deviation characteristic of a three-phase circuit breaker, so that the calculated phase value is set as a target closing phase of the first closing phase. A closing phase that produces the smallest energization flux error when a residual flux of zero is calculated, so that the calculated phase value is set as a target closing phase of the remaining two phases. The total time required from the reference point to the target closing phases of the remaining two phases and a delay time corresponding to an integer multiple of a given cycle of the three-phase power supply is set as a target closing time of the remaining two phases.

Providing an antenna device and a portable radio communication device whose conductive plate for use in reducing the amount of the electromagnetic waves to be absorbed into a human body can be reduced in size. The portable radio communication device 1 includes a circuit board (not shown) necessary for performing radio communication, shield case 2 as a ground conductor which shields the circuit board, a conductive plate 3, an antenna feeding portion 4, and an antenna 5. The circuit board, shield case 2, and conductive plate 3 are enclosed by a housing (not shown) made of nonconductive material. The conductive plate 3 has its one end along the longitudinal direction connected to the shield case 2 to form a short circuit via the conductor 7, and has its other end electrically opened from the shield case 2. The conductive plate 3 has two slits 8a, 8b near the conductor 7.

Amusement facilities for providing predetermined images to passengers inside a vehicle for amusement on the basis of a scenario while the vehicle (ride)(1) is moving in a predetermined course, wherein the course includes bright areas and dark areas, and acceleration/deceleration of the ride (1) is done at the boundaries of these areas. A video camera (11) provides images outside the vehicle to the passengers in the bright areas and images of a video disk player (34) are provided to the passengers in the dark areas. Further, sways are imparted by a motor (23) for rolling and a motor (24) for pitching to the ride (1) in accordance with scenarios. These images, acceleration/deceleration and sway give the passengers an illusion as if they had moved over a longer distance than an actual distance in the dark areas.

A composite reverse osmosis membrane has a polyamide type skin layer whose specific surface area ranges from 3 to 1000. The composite reverse osmosis membrane of this invention is superior in the salt rejection property and water permeability. The composite reverse osmosis membrane comprises a negatively-charged crosslinked polyamide type skin layer obtained by reacting a compound having polyfunctional amino groups and a polyfunctional acid halide compound having polyfunctional acid halide groups, and a microporous support to support the skin layer. The specific surface area of the skin layer is at least 3. A first stage of reverse osmosis treatment is carried out in a membrane module using this composite reverse osmosis membrane. The skin layer can be coated with a layer of an organic polymer having positively-charged groups e.g. polyethyleneimine in order to be used as another membrane module. The organic polymer of this case is crosslinked, for example, by glutaraldehyde. The layer which is crosslink-coated on its surface area is a composite reverse osmosis membrane excellent in desalination of mineral salt in a low-concentration region and removal of cationic organic materials.

An antenna apparatus for use in a portable cellular telephone that can avoid deterioration in signal radiation characteristics caused by the adverse influence of a user's head during the use of the telephone. Two sleeves have been fixed to a housing for a portable cellular telephone. A linear radiating conductor having a .lambda./4-electrical length is slidably supported by the housing by way of the two sleeves so that it can be both freely pulled out of or accommodated in the housing. The radiating conductor is extended at one end on the side of the power-feed point by a length equivalent to n.lambda./2. Also, a tubular conductor is coaxially disposed with the extended portion so as to form a power-feed coaxial line. When the radiating conductor is pulled out of the housing to such a degree as to reveal the coaxial line, the monopole antenna projects sufficiently away from a user's head, and a deterioration in signal radiation characteristics can thus be prevented.

A DC circuit breaking device is provided for interrupting the transmission of direct currents to an electric power system by making external changes to an arc generated upon contacting or separation of contacts 11 and 12 in order to rapidly extend and vibrate arc currents. In a self-excited commuting DC circuit breaking device, coils 41 and 42 opposed to a fixed and a movable contact 11 and 12, respectively, are disposed around the outer circumferences of the contacts 11 and 12, and currents flowing through a commutation circuit or the contacts 11 and 12 are allowed to flow through the opposed coils 41 and 42 so as to apply magnetic fields to the neighborhood of an arc. This constitution provides the DC circuit breaking device with high performance that it can rapidly extend and vibrate arc currents to thereby interrupt direct currents.

A single-point bonder is provided ultrasonically bonding lead fingers extending along different directions onto a semiconductor chip with satisfactory reliability. The bonder contains a first bonding tool for bonding a first set of lead fingers onto a semiconductor chip using a first ultrasonic vibration along a first direction, and a second bonding tool for bonding a second set of lead fingers onto the chip using a second ultrasonic vibration along a second direction different from the first direction. Preferably, the first bonding tool has a first ultrasonic horn for transmitting the first ultrasonic vibration. The second bonding tool has a second ultrasonic horn for transmitting the second ultrasonic vibration. The first and second horns extend along the first and second directions, respectively. The first and second ultrasonic vibrations are parallel to the longitudinal directions of the first and second horns, respectively. The first ultrasonic vibration may be parallel to the longitudinal directions of the first horn, and the second ultrasonic vibration may be parallel to a rotation direction of the second horn.

This invention relates to an internal combustion engine and a control device for the internal combustion engine and has an object to provide an internal combustion engine and a control device therefore that can suppress occurrence of knocking if an EGR rate is increased. An EGR gas can be made to flow separately through one path via one EGR passage and an other path via another EGR passage. The EGR gas flow through the other path can be cooled by an intercooler. Since the intercooler usually has a capacity larger than that of an EGR cooler, its cooling capability is high, and the EGR gas can be made to flow into a surge tank in a state where heat of the EGR gas has been sufficiently emitted.
