Title: Intrusion preventing sensor
Inventor: OSAWA TSUNEJI
IPC: G01J1/02
Filed: 1990-08-07
Abstract: PURPOSE:To obtain an intrusion preventing sensor wherein the alignment of the optical axis of the sensor is simple, many pyroelectric type infrared-ray sensors are assembled in parallel and the boundary surface can be broadly covered by arranging a conductive honeycomb member in front of a lens when a pyroelectric type infrared-ray sensor is adopted. CONSTITUTION:Infrared rays which are obliquely cast into a lens 7 are cut in a small-diameter tube with a honeycomb member 8. The surface of the lens 7 is covered with the opening part of the above described small-diameter tube in the honeycomb state. The flow of air and irregular air stream on the surface of the lens 7 are prevented. The diameter of the inner circumference of an inner tube 5 of a hood 1 wherein the honeycomb member 8 is located is larger than the opening part of the tip of the hood 1. The gap is expanded. Therefore the speed of the air through the opening part is reduced. The expanding part contributes to the heat dissipation of the honeycomb member 8 itself. The hood 1 has the double structure comprising an outer tube 4 and an inner tube 5 through a heat insulating spacers 2 and 3. Therefore, the external heat conduction is suppressed utmost. Thus the change in temperature in the hood 1 becomes very low.

Title: Optical information recording and reproducing method
Inventor: SASA NOBORU
IPC: G11B7/24041
Filed: 1990-08-10
Abstract: PURPOSE:To secure the recording density of about 8 times as high as conventional by using a secondary harmonic produced from a nonlinear optical material layer in an information recording medium. CONSTITUTION:An optical information recording medium contains the 1st and 2nd recording layers 3 and 4 having the high and low reflection factors respectively to the secondary harmonic of the information writing laser which are laminated successively at the side of a substrate 1. Then the recording medium is irradiated by the laser beam from the side of the substrate 1. The light absorbing quantity is adjusted to the secondary harmonic for the recording performed at a 1st signal level to form the bit to the layer 3 only and also for the recording performed at a 2nd signal level to form the bits to both layers 3 and 4. In this case, the laser beam used for recording and reproduction of the information is identical with the secondary higher harmonic produced by a nonlinear optical material layer of the laser beam to be used. Therefore the area of the bit to be formed is reduced down to about 1/4 and the information can be written to both layers 3 and 4. Thus the recording density of about 8 times as high as conventional is secured.
