摘要： PROBLEM TO BE SOLVED: To improve the productivity of a small antenna and to easily mount it on a printed circuit board at a subsequent process. SOLUTION: A dielectric matrix 10 that is partitioned into many dielectric chips 14 with V grooves 12 formed on one face in a grid-like shape is prepared. A radiation conductor pattern 16 is formed in each dielectric chip on the face of the V grooves 12 of the dielectric matrix 10, a ground conductor pattern 18 is formed on the opposite face in each block of each dielectric chip and a feed pin 20 is subsequently erected. A peelable sheet 30 for covering the blocks of the entire dielectric chips is stuck to the face where the ground conductor patterns 18 are formed through a double-sided adhesive sheet 28. Many small antennas stuck to the peelable sheet 30 are obtained by dividing the dielectric matrix 10 along the V grooves 12 in this state.

摘要： PROBLEM TO BE SOLVED: To make it possible to accurately detect even in the case of faint fluorescence by detecting the fluorescence generated by irradiation of fluorescent substance such as sheet with ultraviolet rays with an optical system having different focuses of visible ray region and ultraviolet region. SOLUTION: The exciting ray of the ultraviolet region generated from an exciting light source 2 is projected to a material 1 to be detected except the visible ray component with an optical fiber 4. The fluorescence of the visible ray region is emitted from the fluorescent substance of the material 1 to be detected and introduced into an optical filter 7. The filter 7 is installed to transmit only the visible rays but also transmit the reflected exciting ray of ultraviolet region through it is slight. The fluorescence of the visible ray region transmitted through the filter 7 is transmitted through a SELFOC lens arrays 8 which has a feature of shorter focus for UV ray than hat of visible ray, and focused on the surface of a photodetector 3. The ultraviolet ray reflected on the material 1 to be detected is slightly arrived at the photodetector 3 but it is out of focus and hence it does not form image to be uniform pattern. This is processed as noise to accurately detect the focused pattern of the fluorescent substance.

摘要： PURPOSE:To select the light of a required wavelength area and to detect it without using any expensive optical filter. CONSTITUTION:Concerning this fluorescent detector, fluorescent light is emitted from a fluorescent material by irradiating this fluorescent material of an object 2 to be detected with excited light from an excited light source 1, and the fluorescent material of the object 2 to be detected is detected by passing the fluorescent light through an optical system and detecting it with a photodetector 3. As the optical system, a glass block, which is formed in the shape of a rectangular column with La-shaped side faces by synthetic crystal glass not to generate fluorescent color with ultraviolet rays and forms a detecting plane 4, is used and the wavelength of the excited light is reflected on the outside face of a bending part 6 at this glass block but the wavelength of fluorescent light generated from the fluorescent material is transmitted at the angle of a formed slope 7.

摘要： PURPOSE:To obtain the small sized detection section by adopting a plastic optical fiber not transmitted through an ultraviolet ray as a fluorescent light transmission line used to sending a fluorescent light emitted from an object to be detected to an optical detector so as to detect the fluorescent light with high sensitivity and isolating a light source of the detector and the detection section. CONSTITUTION:A stimulated light emitter from a stimulation light source 1 is collected by a condenser lens 10 and made incident on an emission light transmission line 3. Since an ultraviolet ray is transmitted through the emission light transmission line 3, only the ultraviolet ray in the stimulated light is emitted to an object 2 to be detected through a detection widow 9 by passing the ray to the optical filter. When an ultraviolet ray is emitted, a fluorescent substance of the object 2 to be detected is stimulated and a fluorescent light is emitted from the fluorescent substance and the fluorescent light passes through the detection window 9 and made incident on a fluorescent light transmission line 5. Since the fluorescent light transmission line 5 has a property of hardly transmitting an ultraviolet ray but passing easily a visual light, the ultraviolet ray is separated in the fluorescent light transmission line 5 without use of an optical filter when the fluorescent light color is within a visual light region. The ultraviolet ray is emitted from the fluorescent light transmission line 5 and received by a photodetector 4.

摘要： PURPOSE:To downsize a rigid circuit board by connecting the wire bonding pads of a flexible glass epoxy wiring board directly with the pads of an electronic component through wire bonding thereby eliminating the need of individual joints for the flexible wiring board and the electronic component. CONSTITUTION:A flexible glass epoxy wiring board 17 is bonded, on one end side thereof, to the vicinity of a bare chip component 13 mounted on an aluminium base circuit board 11. The flexible glass epoxy wiring board 17 has one end side where wire bonding pads are formed, the other end side where various components 21 of control/protective circuit for bare chips are mounted, and an intermediate part, i.e., a flexible interconnection part. Pads 19 of the flexible glass epoxy wiring board 17 are connected electrically with the pads of the bare chip component 13 by wire bonding 25. Since electrical connection is established through wire bonding, necessary area of rigid circuit board can be decreased resulting in downsizing.
