Title: Ventilating device
Inventor: OSHIMA KANEFUSA
IPC: F24F7/08
Filed: 1991-04-09
Abstract: PURPOSE:To execute an easy and rapid detachment and attachment of a filter without allowing the dusts to scatter from the upper surface of the filter by a method wherein the lower part of the filter is moved toward a downstream side against the force of a compression member to release its locking part from a mating engaging member and the filter is then detached while being tilted. CONSTITUTION:When a filter 18 is clogged by the use of a ventilating device, the filter 18 is detached therefrom to be cleaned. More specifically, a decorative panel 24, together with a supporting frame 23, is first removed from a ceiling and the lower part of the filter 18 is then grasped and moved toward a downstream side against the force of a compression spring 20 to tilt the filter 18. At this time, the compression spring 20 and a packing 22 are both deflected. With a locking pawl 19 released from its engaging position by the tilting of the filter 18, the filter 18 is pulled downwards and removed from the inside of an inserting groove 16 while allowing its peripheral aluminum frame to slidably contact with the end of the compression spring 20. In this way, the dusts accumulated on the upstream side surface of the filter 18 can be prevented from scattering therefrom.

Title: Optical element
Inventor: ITOU NORIYASU
IPC: G02B1/10
Filed: 1984-04-18
Abstract: PURPOSE:To absorb infrared rays, ultraviolet rays, and visible range light other than near ultraviolet rays without providing any interference on an element surface nor spoiling its characteristics by providing a specific impregnated material layer on the surface of a plastic transparent body. CONSTITUTION:The impregnated material layer 1a which transmits light with wavelength within a specific range as to visible rays and absorbs light outside the range is formed on the surface of a transparent body formed of plastic, e.g. lens 1, filter for absorbing infrared or ultraviolet rays, and condenser lens 3. This impregnated material layer 1a uses a coloring agent made of dispersed dye. This coloring agent has minimum transmissivity to, for example, about 520nm wavelength and cuts off >=600nm long-wavelength light and <=480nm wavelength light. The colored layer 1a on the surface of the optical element is formed by being impregnated with the coloring agent, so uniform light is transmitted regardless of the thickness of the element. Consequently, the optical element which transmits light rays within the visible range of specific wavelength and absorbs light with wavelength outside the specific range while maintaining the characteristics of the optical element is obtained.

Title: Surface acoustic wave gyroscope
Inventor: YUGAWA KAZUHIKO
IPC: G01C19/56
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a surface acoustic wave gyroscope by which a signal corresponding to precise Coriolis' force is detected without being subjected to the influence of surface acoustic waves. SOLUTION: A driving electrode 22 and a detection electrode 23 are arranged so as to be faced on the surface of a piezoelectric substrate 21, and surface acoustic waves which are generated by applying high-frequency waves to the driving electrode 22 from a high-frequency power supply 3 are propagated to the detection electrode 23. When the piezoelectric substrate 21 performs a rotation around the z-axis, Coriolis' force, in the y-axis direction, whose phase is displaced by 90 deg. due to an interaction with the surface acoustic waves is generated, and the force is converted into a voltage due to a piezoelectric effect so as to appear on the detection electrode 23.  A switching circuit 5 samples the voltage of the detection electrode 23 at a timing at which the amplitude of the surface acoustic waves becomes 0 on the basis of the high-frequency waves which are generated by a delay circuit 4 and whose phase is identical to that of the surface acoustic waves in the detection electrode 23, and it outputs the voltage to an integrator 6. When the generated voltage of the detection electrode 23 is extracted at the timing at which the amplitude of the surface acoustic waves becomes O, precise Coriolis' force which is not affected by the surface acoustic waves can be detected.
