摘要:
A voice coil type linear motor with a cooling function. A closed magnetic circuit formed into the θ-shape, by an inner yoke provided between a pair of outer yokes made up of magnetic materials arranged in parallel with a longitudinal center axis in such a manner as to be in parallel with the pair of outer yokes. The outer yokes and side yokes are provided at both end portions of the inner yoke. Permanent magnets are provided on inner sides of the outer yokes and on outer sides of the inner yoke with polarities thereof which face opposite surfaces of the outer yoke. The inner yoke is made opposite to each other or with polarities thereof which face only the outer yokes being made opposite each other to thereby a field. An armature made up of a bobbin of non-magnetic and insulating materials is provided. A coil is provided around the bobbin between the permanent magnets via air gaps in such a manner as to move in an axial direction or in such a manner that. The coil is wound around the bobbin. A case is constructed on an exterior of the bobbin. A coil portion is made watertight. A fluid supply port and a fluid discharge port are provided on the bobbin or the case. A cooling fluid is caused to flow between the coil and the case so that the coil is cooled directly.

A small vacuum chamber is provided which needs no load lock chamber. In a voice coil type linear motor including a closed magnetic circuit formed into the θ-shape, by a pair of outer yokes (11), an inner yoke (12) and side yokes (13) and in which an armature is fixed to an inner side of the outer yoke (11), whereas permanent magnet sides are allowed to move, a coil (18) is wound around a bobbin (17), an exterior case 23 for the bobbin is constructed so as to make a coil portion watertight, and a fluid supply port and a fluid discharge port are provided either on the bobbin or on the case, whereby a cooling fluid is made to flow between the coil and the case so as to cool the coil directly.

Split cores comprising laminated iron cores each having formed thereon a tooth, and a yoke and a pole piece which are connected to the tooth at both ends thereof, and arranged and connected together into an annular shape to make a stator. Both ends of the yokes and both ends of the pole pieces are displaced in one circumferential direction by laminated iron core from a top laminated layer of the iron cores of the split cores to a bottom laminated layer of the iron cores or split cores.
摘要:
Although in a conventional permanent magnet type synchronous motor, cogging torque is reduced by displacing permanent magnets of a rotor in a circumferential direction or displacing a stator core in a circumferential direction, since the skew so produced reduces the output of the motor and moreover the winding work of windings cannot be automated to make the resulting motor highly expensive, split cores are provided which solves those problems and enables the winding work of windings to be automated so as to obtain an inexpensive and high-output motor.There are provided a plurality of split cores (100) made up of laminated iron cores each having formed thereon a tooth (6), and a yoke (5) and a pole piece (9) which are made to connect to the tooth (6) at both ends thereof, and arranged and connected together into an annular shape to make up a stator, characterized in that both ends of the yokes (5) and both ends of the pole pieces (9) are displaced in one circumferential direction by laminated iron core from a top laminated layer to a bottom laminated layer of the iron cores of the split cores.

The present invention provides a surface treatment method for a water-absorbing resin comprising three steps of: 1) a humidifying and mixing step for mixing a base polymer and a surface cross-linking agent solution to obtain a “humidified substance”; 2) a pretreatment step for raising temperature of said humidified substance to obtain a “pretreated substance”; and 3) a surface cross-linking reaction step for cross-linking said pretreated substance to obtain a surface cross-linked “water-absorbing resin”; wherein dew point in the pretreatment step of the above 2) is from 50° C. to 95° C., and temperature of said humidified substance is raised from temperature below the dew point up to a temperature of 10° C. higher than the dew point.

An absorbent member and a method for making such an absorbent member. The absorbent member includes a modified water absorbent resin having good production efficiency, absorbency against pressure, absorption speed, gel strength, and liquid permeability. The modified water absorbent resin may be made by mixing a water absorbent resin, water, and a water-soluble radical polymerization initiator without addition of an ethylenically unsaturated monomer to obtain a water absorbent resin composition, and irradiating the water absorbent resin composition with active energy rays. During irradiation, the surface water content of the water absorbent resin is at least 3.0 wt %.

A packing package includes a gusseted container formed from laminated films and having opposite side walls and gussets extending between the opposite side walls, and a spout attached to an opening in the gusseted container. The laminated film forming either the two opposite side walls or the gussets is provided with a heat insulating barrier. The laminated film forming the gussets is not provided with any heat insulating barrier when the two opposite side walls are formed from the laminated film provided with a heat insulating barrier. The laminated film forming the two opposite side walls is not provided with any heat insulating barrier when the gussets are formed from the laminated film provided with a heat insulating barrier.

The present invention provides a pseudorandom number generating system, an encryption system, and a decryption system. The pseudorandom number generating system of the present invention repeatedly performs simple transformation of a non-secure pseudorandom number sequence that may be generated quickly, and thus may quickly generate a highly secure pseudorandom number sequence having a long period. In addition, the encryption system and the decryption system of the present invention do not generate a large encryption function difficult to be deciphered based on a shared key 122, but prepare multiple functions 126, which perform fast, different types of transformation, and select a combination of functions determined based on information of the shared key 122, and make the selected functions transform a text multiple times, thereby encrypt the text. Each of the functions is basically fast, and thus transformation by the entire combination is also fast. Furthermore, since the combination of functions and repetitive count for them can be changed, future improvement in specification is easy. Moreover, security is high since which functions are applied in what order is unknown.

A drive control apparatus for a vehicle includes: a follow-up control device; a stop hold device that is capable of holding the vehicle in a stopped state by controlling a brake pressure; and a driving operation detection device that detects at least one of a brake operation and a shift operation to a reverse or neutral position, wherein the follow-up control device cancels the holding of the vehicle in the stopped state by making the stop hold device cancel the holding of the vehicle in the stopped state after holding the vehicle in the stopped state for a predetermined time period or by making the stop hold device gradually reduce the brake pressure when the driving operation detection device detects at least one of the brake operation and the shift operation to the reverse or neutral position while the vehicle is held in the stopped state.
