Filed: 1987-12-21
Abstract: PURPOSE:To enable detection of defects in a liquid-crystal mask, by providing a polarizing filter between a laser oscillator and the liquid-crystal mask, provid ing a beam splitter between the mask and a projection lens to branch a laser beam, and picking up an image by a television camera. CONSTITUTION:A laser beam from a laser oscillator 1 is polarized directly by a polarizing plate 2, and is projected through a liquid-crystal mask 4. The mask 4 is provided with a required printing pattern by a liquid crystal controller 8, and the laser beam is transmitted, without changing the plane of polarization, through the area provided with the printing pattern. The laser beam transmitted through areas other than the printing pattern area of the mask 4 has the plane of polarization rotated by 90 deg. upon the transmission, and is then separated through reflection by a beam splitter 5. The rotated laser beam 16B reflected by the beam splitter 5 is attenuated by an attenuator 10, and is picked up as an inverted image by a television camera 13. The image is binary coded by an image recognition device 15, and is compared with an image obtained under a normal condition, whereby an abnormality in the mask 4 is detected.

Title: Air stream control structure for ventilating part
Inventor: TEI SHIMEI
IPC: F24F13/06
Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To permit application of an air stream control structure on various structural body of a ventilating part, reduce a pressure loss as well as noise and prevent condensation when an air temperature is low, by a method wherein a flap for an indoor machine is arranged so as to be existing in the ventilating part through which air stream is passed, while the leading edge of the flap is provided with the structure of serration. SOLUTION: In an air outlet port of a ventilating part, a structural body for air flow direction control or a flap (louver) 3 and a plurality of vertical vanes 5 are provided in an air outlet passage while saw-tooth type serration structural parts 4 are formed on the leading edges 3a, 5a on the upstream side of air stream. Upon cooling or heating operation, air stream passes the serration structural parts 4. In this case, air stream generates vertical vortexes from both ends of a plurality of crests of the serration parts. The vertical vortexes promote the mixing of turbulent flows and supplement the moment of flow near the negative pressure surface of the flap 3 and vertical vanes 5 to restrain the separation of flow of air, whereby the stream of air on both surfaces of the flap 3 as well as the vertical vanes 5 is smoothed and aerodynamic noise is reduced.

CONSTITUTION:A specimen undergoes HF treatment and washing with water 6. Then a natural oxide film 4 is removed. An atom layer 7 of water and the like is adsorbed in place of the film 4. The washing with IPA vapor and drying 8 are performed. Then, the atom layer 7 of the water and the like is substituted, and an alcohol group layer 9 is adsorbed. Then the wafer is introduced into a UV treating chamber through a vacuum chamber, and ultraviolet rays are projected 10. Then the alcohol group is released from the surface of an Si substrate 1. Under the state wherein an outermost surface 11 of the Si substrate 1 is exposed, the specimen is introduced into a CVD chamber through the vacuum chamber. W 12 is deposited. Atoms such as oxygen atoms which are the cause for local intrusion of W are not present at a 11 in the surface of the Si substrate. Therefore, an interface 13 between the W 12 and the substrate 1 is flat. The local intrusion of the W does not occur. Finally, an Al wiring 14 is formed, and the wiring formed with the W and the Al is flattened.

Consequently, the PG pattern in plural positions coincides with the magnet pattern 2a on the rotor side once in one revolution or once during a horizontal movement, and a large PG output is obtained. Also, since the intervals of the PG patterns are respectively all different, the PG output is kept low except at the coincided timing, and only the PG output for the purpose of the phase detection is largely outputted. Thus, the improvement of S/N ratio in the PG detection and the increase in detecting the accuracy of the PG pulses are attained.

Since both sides in the moving direction of the panel 2 are restricted with restriction members 6, the defect of both sides of the panel 2 can be prevented when pressed with the die roll 1. Moreover, by restricting/ protecting the front and rear in the moving direction of the panel 2 with another adjoining panel 7, the defect of both sides of the front and rear in the moving direction can be prevented.
