[Subject] To provide laser Doppler blood flow measuring method and device which achieve multi-dimensional measurement efficiently at a high degree of accuracy over a wide range with a simple optical system and device.[Solving Means] Laser light from a semiconductor laser 12 is split and formed into sheet lights Ls using a cylindrical lens 22, and the sheet lights Ls are crossed with each other at a predetermined position. A lens system 30 configured to form an image of scattered lights into a linear shape at a linear irradiation site Lx where the sheet lights Ls cross with each other is provided. An optical fiber array 32 having a plurality of optical fibers 34 is provided at an image-forming position of the lens system 30. Avalanche photodiodes 42 configured to convert the scattered lights which are shifted in frequency by the Doppler effect caused by the blood flow into electric signals for the each optical fiber 34 are provided. The blood flow velocity in a tissue of a biological body at the linear irradiation site Lx is calculated from the scattered lights transformed from the laser light by being shifted in frequency by the Doppler effect and is scanned for the each optical fiber 34, whereby the blood flow velocity in the blood vessel in a predetermined area in the biological body is calculated.

A multifunction system has advanced functions and high speed capability and is excellent in expandability. The multifunction system includes a controller, an IIT, an IOT, and a light distributing device. For a print job, print data outputted from the controller is converted into optical signals, which enter a light distributing device and are transmitted to the IOT of the emission side. The IOT prints the received data onto a printer. For a copy job, copy data outputted from IIT is converted into optical signals, which enter the light distributing device, and are transmitted to the IOT of the emission side. For a scan job, scan data outputted from the scanner is converted into optical signals, which enter the light distributing device, and are transmitted to the controller of the emission side. The controller processes the received data.
摘要:
A wear resistant, heat resistant conveyor chain comprising a series of links, each having a heat resistant roller rotatably fitted onto a bush between inner plates. The links are interconnected in the longitudinal direction of the chain by outer plates, and connecting pins rotatably inserted into the bush. A wear resistant, heat resistant sleeve-shaped spacer protrudes beyond the end surfaces of the heat resistant rollers toward the right and left inner plates to eliminate any sliding contact between the end surface of the heat resistant roller and the inner side surface of the inner plate.
摘要:
There is provided an optical disk drive capable of appropriately effecting recording and reproducing operations without being affected by offset values and a laser output value, which are set at startup of the disk drive, even when changes have arisen in the internal temperature of the disk drive because of changes in ambient temperature. In an optical disk drive, a temperature sensor provided on a pickup measures a temperature. When changes in temperature are greater than a predetermined level, a focus offset value, a tracking offset value, and a value of laser output from the pickup are reset.

A process for printing or coating a substrate with a liquid-crystalline composition and at least one non-liquid-crystalline print or coating as a multilayer and a substrate produced by this process is described. The liquid-crystalline composition contains at least one compound having two polymerizable groups and at least one compound having only one polymerizable group, and optional further additives. The non-liquid-crystalline print or coating contains one or more IR- or UV-absorbent or fluorescent dye or pigment. The process and the printed substrate are useful in producing counterfeiting-proof marking of articles.
摘要:
A chamfering portion provided at an inlet corner of a port of an inside way-out in a governor shaft is effective to decrease energy loss of fuel flowing into the inside way-out to less than one half in comparison with that of a conventional art. A flow amount characteristic of the fuel into the inside way-out improves so that a hysteresis between a pump chamber pressure decrease characteristic on increasing a load (a retarding characteristic) and a pump chamber pressure increase characteristic on decreasing the load (an advancing characteristic) is lowered, resulting in securing a highly accurate control of fuel injection timing.

An oil-free chain has bushings which protrude from the outer surfaces of the inner link plates into which they are press-fit, and extend into bushing supporting bores formed in the inner surfaces of the outer link plates of the chain. These bushing supporting bores are formed by a pressing operation which produces offsets in portions of the outer plate, so that, as the bushing supporting bores are formed in the inner surfaces of the outer plates, bosses are simultaneously formed on the outer surfaces. The connecting pins of the chain are press-fit into pin holes in these bosses. The bushing supporting bores are formed without removal of material by machining, and therefore the strength of the outer plates is not compromised.

In a chain transmission in which a roller chain transmits power from a driving sprocket to one or more driven sprockets, the sprocket teeth are shaped so that at a location radially outward from the sprocket pitch circle, the distance between the front surface of each sprocket tooth to a radial reference line from the sprocket center through the center of the tooth root, is at least as great as the distance from the centerline to the front tooth surface at the pitch circle. The tooth faces merge smoothly with the tooth gap bottom, the sprocket root diameter is smaller than the root diameter according to ISO standards, and the radius of the arcuate tooth gap bottom is greater than the radius of the chain roller.
