摘要:
An overcurrent protection device for a motor M with an overheat prevention function having a housing 10 with fixed contacts 16, 18 and movable contacts 24, 26. A first snap acting bimetallic element 20 in the device is responsive to heat from overcurrent conditions and a second snap acting bimetallic element 40 is responsive to heat from the temperature for the motor M. The movable contacts 24, 26 are controlled by the first bimetallic element to cause engagement or nonengagement with the stationary contacts 16,18. Coupling members 42, 44 contained in the housing engage both bimetallic elements 20, 40 and allow the first overcurrent bimetallic element 20 to snap independently of the second bimetallic element 40 while providing for snap action of the second bimetallic element 40 to also cause the first bimetallic 20 to snap.

A plurality of memory modules are stacked so as to form a multilayer integrated memory circuit. All of the memory modules have a plurality of bare memory IC chips mounted thereon, and have the same structure, the same circuit configuration and the same terminal arrangement in lead frames with each other. Each of the memory modules to be stacked in each layer is rotated by 90.degree., 180.degree. or 270.degree. before being stacked and connected to each other. Thus, in the multi-layered memory circuit, it is possible that signals can be selectively input/output to/from a particular layer in the multilayer structure, although the lead terminals of each of memory modules has the same configuration and the same arrangement with each other. As a result, a small-size integrated memory circuit device with a large memory-capacity can be provided, which can be fabricated easily and efficiently. A higher processing speed of digital computers can be also achieved.

A horizontally split casing of a turbo machine, such as a centrifugal compressor, including one half casing formed with scroll grooves on an inner peripheral surface thereof, and the other half casing formed with cutouts in portions thereof corresponding to outlet scrolls. A second casing formed on an inner peripheral surface thereof with scroll grooves is attached to the other half casing in a manner to enclose the cutouts. The horizontally split casing of this construction is low in cost and yet enables a compact size and a light weight to be obtained in a horizontally split casing of a turbo machine.

A damped bearing device operative to damp vibration acting on a bearing journalling a rotary shaft includes a spring body resiliently supporting the bearing with respect to a housing. The spring body includes a spring portion arranged on the outer peripheral side of the bearing to minimize the axial dimensions of the bearing device without increasing the stress produced in the spring portion of the spring body.

The object of the present invention is to provide (1) a cell sorter, (2) a flow cytometer capable of detecting sideward scattered light, (3) a method for accurately measuring cell concentration, (4) a method for multicolor staining analysis without a fluorescence correction, and the like, which satisfy requirements that carry-over and cross contamination of samples do not occur.The object can be solved by an apparatus for separating particles comprising: a flow cell wherein a flow path is formed in a flat substrate, an illumination unit configured to illuminate the particles in a sample liquid flowing through the flow path, a detection unit configured to detect particles of interest by detecting scattered light or fluorescence from the particle when the particle is illuminated, and identifying the particle based on its signal intensity, a constant-pressure pump which applies a pressure pulse to the particles in the sample liquid flowing through the flow path in the flow cell, and an electromagnetic valve connected thereto, and a control unit configured to control the movement of the electromagnetic valve based on the signal from the detection unit.
摘要:
A metal vapor discharge lamp and a lighting fixture are downsized without causing breakage of an outer tube because of optimization of a positional relation among the outer tube (34), an inner tube (32), and an arc tube (40). The metal vapor discharge lamp has the arc tube, the inner tube housing the arc tube, and the outer tube housing the inner tube. The positional relation satisfies the relation of 2×A+B≧1.06. In a cross section of the lamp (the cross section of the arc tube is unshown for convenience), A (mm) represents the shortest distance between the arc tube and the inner tube along a line in a radial direction of the inner tube, and B (mm) represents a distance between the inner tube and the outer tube on a line segment C that is extension of the line.

According to one embodiment, a method for manufacturing a thin film magnetic head includes forming on a substrate magnetic head portions having a magnetoresistive element and resistance detection elements for measuring an amount of polishing; slicing the substrate to form at least one row bar; polishing the ABS of each row bar; forming rails on the polished ABS; and cutting each row bar to separate each magnetic head portion. The step of polishing the ABS includes measuring a resistance of each resistance detection element and a resistance of each magnetoresistive element; calculating an offset value between the resistance detection element and the magnetoresistive element; and calculating a final resistance of the resistance detection element by using the calculated offset value. When the resistance of the resistance detection element reaches the final resistance, polishing of the ABS of the row bar is terminated. Other methods are presented as well.

摘要:
To improve the laser annealing process for polycrystallizing amorphous silicon to form silicon thin films having large crystal particle diameters at a high throughput, the present invention is directed to a process of crystallization by irradiation of a semiconductor thin film formed on a substrate with pulsed laser light. The process comprises having a means to shape laser light into a linear beam and a means to periodically and spatially modulate the intensity of pulsed laser in the direction of the long axis of the linear beam by passing through a phase-shifting stripy pattern perpendicular to the long axis, and collectively forming for each shot a polycrystalline film composed of crystals which have grown in a certain direction over the entire region irradiated with the linear beam.
