In a fluid pump device, a filter is secured to a housing. A meshed portion of the filter substantially covers an inlet opening of the housing. Each engaging projection of the filter is engaged with a corresponding engaging recess of the housing in a direction perpendicular to an axial direction of an impeller. Arm portions of the filter substantially perpendicularly extend with respect to a meshed portion of the filter and are resiliently flexible in the direction perpendicular to the axial direction of the impeller. Each coupling projection of the filter is provided between adjacent two arm portions of the filter and is engaged with a corresponding coupling recess of the housing in the axial direction of the impeller.

In a commutator of an armature of an electric motor, a plurality of segments are arranged on the outer peripheral surface of a commutator ring at equal angular intervals. The segments which are in the same phase and oppose with 180° angular interval are connected through a conductive plate. Each conductive plate is spaced apart a predetermined distance from adjacent ones in the axial direction not to short, and molded within the commutator ring. Each of brushes is shaped to have a width which is sufficient to bridge over three segments. Alternatively, the commutator ring may be shaped to have a tapering protrusion part (25c) and the same-phase segments may be directly connected by a shorting wire along the tapering protrusion part.

A battery case comprising a case body, a closure for closing an open end of the case body, a pivotal plate pivotally movably supported in the vicinity of an opening edge of another open end of the case body for covering this open end, and a spring attached to the case body externally thereof for biasing the pivotal plate inwardly of the case body. Contact pieces are provided on the closure and the pivotal plate each on the inner surface thereof and adapted to contact the positive electrode and the negative electrode of a battery respectively.

The laser transfer machining apparatus comprises a shaping unit for shaping the laser beam so that the laser beam has a beam pattern which corresponds to a desired pattern to be machined in the object to be machined and a generating unit disposed separately from the shaping unit for simultaneously generating a plurality of laser beams each having the beam pattern from the laser beam shaped by the shaping unit. The generating unit is adapted to emit the plural laser beams while simultaneously defining a plurality of radiation directions of the generated plural laser beams to the object to be machined. The laser transfer machining apparatus can provide a high efficiency of utilization of light and reduce the time required for machining. Furthermore, the laser transfer machining apparatus can utilize a laser with a relatively low spatially coherence such as an eximer laser.

As regards a surface light source device for use with back-light or the like of a transmissive display panel, the efficiency of the cooling structure for the device will be improved and dust and dirt will be prevented from adhering.The surface light source device has a housing, a diffuser panel, a reflective plate, lamps, and an electric circuit portion. The housing has a window portion located ahead, a base portion located behind and side portions forming a flat space by connecting the two. The diffuser panel is mounted to the window portion of the housing. The reflective plate is supported by the side portions and partitions the flat space into a closed space ahead and an open space behind to be interposed therebetween. The lamps are housed in the closed space, and are positioned right above the reflective plate and right under the diffuser panel to radiate light toward the diffuser panel. The electric circuit portion is housed in the open space, and is electrically connected to the lamps to light them up. On the side portions of the housing, there are formed openings, through which cooling air supplied from outside is introduced into the open space to diffuse heat accumulated within the housing.

In a printer control system, a monitor unit monitors whether print document data or a print document consisting of a group of such print document data has been received within a given time. A schedule attribute judging unit judges whether the job processing scheduling attribute of the received print document data or print document is a before-complete attribute or an after-complete attribute. In the case of the before-complete attribute, a print document data processing unit is used to process the print document data. On the other hand, in the case of the after-complete attribute, a print document processing unit is used to process the print document. When a job is interrupted, a document addition judging unit is used to judge whether the job interrupted but received later again can be added to the last print document data or to the last print document or not.

A fine particle dispersing apparatus including a cylindrical body, a funnel nozzle provided at the bottom of the cylindrical body, and a valve having a clearance forming member forming a clearance with the inner wall of the funnel nozzle which is larger than the diameter of the fine particles. The funnel nozzle and/or the clearance forming member oscillates, thereby causing the fine particles present within the funnel nozzle to pass through the clearance and discharge from the nose portion of the funnel nozzle.

A coating method for applying a coating composition mainly containing an organic solvent onto a running flexible support 11 by ejecting the coating composition in an oversupply state from a slit 9 under pressure. A back edge top end surface 14 on the upstream side in the direction of running of the support with respect to the slit is set so as to be substantially parallel to the surface of the support. A liquid-detached position in which the coating composition ejected from the slit to overflow the slit is detached from a surface of the support 11 is set so as to be placed on the back edge surface opposite to the support.

A front mechanism mounted on a chassis loads a cassette in place by causing a first projection and a second projection on each of opposite side portions of a cassette carrying tray to slide along respective guide grooves formed in each of side plates. Power is transmitted from a drive cam gear provided on the rear side of the chassis to the tray via a drive mechanism, intermediate gear and rotary gear. For loading, the tray initially starts to move as inclined with the first projection and the second projection sliding along slanting grooves and is thereafter lowered by sliding movement of the projection along a vertical groove and sliding movement of the projection along a descent groove while being corrected from the inclined position to a horizontal position. Upon completion of cassette loading, the intermediate gear and the rotary gear constitute a Geneva stop, and the drive cam gear disengages from the drive mechanism. A support guide supporting the drive mechanism is provided by being formed by outsert molding inside the chassis and thereafter being rotated to project from a side portion of the chassis.

A digital operation recorder provided with a recording medium having a data region for recording operation data for each operation of a car, a clock, whose time is correctable, for generating time data, and a write means for successively writing the operation data into the data region within the recording medium at intervals of a preset time and writing, in response to the time data from the clock, such data from which its starting time and ending time can be found out is disclosed. In the recorder, the write means comprises a time write means for writing, every time the operation data of the car is successively written into the data area within the recording medium, the time elapsed after the start of each operation into a first area of the data region such that the currently written elapsed time supersedes the previously written time, and a time-of-day write means for writing, every time the operation data of the car is successively written into the data area within the recording medium, the time of write into a second area of the data region such that the currently written time of write supersedes the previously written time.
