A burglar alarm apparatus to be fitted to an object of protection for detecting a preliminary action of theft by raising an alarm, etc., and also relates to a radio receiver for the apparatus. There have been the problems in the past that the engagement of the apparatus with the object article becomes unstable due to external vibration, etc., or the engagement mechanism is easily tampered with. The apparatus of the invention comprises an electrical holding circuit wherein holding means (VK) for holding alarm output means (AO) for outputting alarm information on the basis of the detection information of preliminary action detection means (SD) for detecting a preliminary action of theft is set to a hold state on the basis of an actuation instruction, and alarm release means (R) comprises a hold release instruction switch for instructing the electrical holding circuit (VK) to release hold by an electrical signal. Accordingly, the apparatus can be made compact as a whole, and the holding means for holding the alarm output means in the operative state can exhibit a stable holding function.

PROBLEM TO BE SOLVED: To efficiently remove foreign matters without causing damage of the surface. SOLUTION: In this apparatus, laser beams emitted from an excimer laser are s-polarized and are irradiated at an angle θ of incidence of e.g. 5 deg. to the surface of a hard disc base sheet 12. Therefore, in comparison with a case of the angle of incidence of 90 deg., the area of irradiation to the hard disc base sheet 12 is increased and the laser density is decreased. In addition, as the laser beams reflected on the surface of the hard disc base sheet 12 are indirectly irradiated to a foreign matter 44, irradiation dose is increased. In addition, as electric vector of the s-polarized laser beams is oscillated in the parallel direction to the surface of the hard disc base sheet 12, this oscillation energy effectively acts as a force for eliminating the foreign matter 44.

PROBLEM TO BE SOLVED: To obtain a defect inspection apparatus in which an inspection processing operation is executed in parallel and in which a processing speed can be doubled by a method wherein a plurality of beam splitters are arranged in tandem on the optical axis of a laser beam and beams of reflected light by the respective beam splitters are received by CCD arrays whose number is identical to that of the beam splitters. SOLUTION: Beam splitters B0 to Bn which are arranged in tandem as n+1 pieces of optical reflection means are fixed in the upper part of a magnetic recording disk 1 in a state such that their reflection faces are tilted by 45 deg. to the same direction. By using the beam splitter B0 which is the closest to the disk 1, a laser beam which is irradiated from a laser light source 3 arranged horizontally so as to face the beam splitter is deflected downward, and the laser beam irradiates the disk face of the disk 1 vertically. When there is defect, the laser beam is reflected diffusely by the part of the defect on the surface of the disk 1, and it is received by CCD arrays C1 to Cn in such a way that a shade part is generated by a pixel. A light received result is output to A/D convertes A1 to An, it is converted into a digital signal so as to be given to an image processing part 4, and luminance data on the CCD arrays C1 to Cn is compared with a luminance threshold for every pixel.

PROBLEM TO BE SOLVED: To arbitrarily utilize a p-polarization component and an s-polarization component. SOLUTION: A laser irradiation apparatus 10 includes a polarizing beam splitter 16 and the laser beam passed through a variable attenuator 14 is split into two orthogonal polarized beams by the polarizing beam splitter 16. The laser beam of a p-polarization component transmitted through the polarizing beam splitter 16 is rotated by 90 in polarization plane centering around an optical axis by a 1/2 wavelength plate and, therefore, laser beam of an s- polarization component is allowed to be incident on a work. The laser beam of the s-polarization component reflected from the surface of the polarizing beam splitter 16 is reflected by a mirror 20 to be incident on the work. Therefore, both surfaces of the work can be washed at once and two works of the same kind can be washed at the same time. When the 1/2 wavelength plate is inserted between the mirror 20 and the work, laser beam of the p-polarization component can be utilized. Therefore, two works of the same kind can be processed at the same time.

PROBLEM TO BE SOLVED: To provide a manhole cover antenna capable of providing an antenna function for a manhole cover without deteriorating cover strength only by simply machining the manhole cover. SOLUTION: The surface of the manhole cover 1 is slightly cut to form a through hole 1b for putting a power feed line through in a center of the cut and recessed part 1a to install a substrate antenna 2 in the part 1a. A base conductor plate 2c on the rear surface of the antenna 2 is brought into contact with the cover 1 to short-circuit. Through the use of the thin substrate antenna 2 as an antenna element, the machining work of the part 1a for arranging the antenna element is minimized and as only the hole 1b for inserting a cable 2d and a connector 2e is provided, the strength of the cover 1 is not deteriorated much.

PROBLEM TO BE SOLVED: To reliably remove foreign objects, to improve the rate of foreign object removal, to prevent the foreign objects from adhering onto a substrate surface again, and to prevent an extremely small amount of scattering. SOLUTION: Compressed fluid is jetted to the outer edge of a spot P from first and second jet ports 38a and 40a of a nozzle 36, and is sprayed at a spraying angle α being smaller than 90 degrees. Each compressed fluid flows within the range of the spot P, and collides one another near the center between the first and second jet ports 38a and 40a. In addition, the compressed fluid that flows within the range of the spot P gives kinetic energy to foreign objects for supporting the peeling/floating of the foreign objects due to laser irradiation. Then, the foreign objects including extremely small ones that are subjected to the peeling/floating swim with the current of the compressed fluid. A suction port 42a is arranged ahead the flow of the compressed fluid that has collided, thus sucking the foreign objects to the suction port 42a with the compressed fluid by allowing suction force to operate.
