Title: Detector provided with filter
Inventor: ITO MITSUYOSHI
IPC: G01N15/08
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To early detect that a filter is closed by clogging, by installing a detecting part which detects foreign matter, and a differential pressure detecting part which detects the difference between the atmospheric pressure in a detection space to a filter and the atmospheric pressure in the outside which is obtained via a penetrating hole. SOLUTION: The air in a room is introduced into a detection space 123 from a filter 121. Whether carbon monoxide exists in the air in the detection space 123 is monitored by a CO sensor 122. When carbon monoxide is detected, a current is outputted to a circuit board 14, and a buzzer 17 is operated. The clogging of the filter 121 is detected on the basis of atmospheric pressure difference between the detection space 123 and the inside of the room. When the clogging exists, atmospheric pressure difference is generated between the inside of the room and the detection space 123. By the difference, a diaphragm in a differential pressure detection part 13 is differentially operated, so that difference is generated in a capacitance. Hence a differential pressure sensor 13 detects the clogging of the filter 121, drives the buzzer 17, and gives the alarm.

Abstract: PURPOSE:To miniaturize a receiver, to reduce the weight of the receiver and to improve the reception sensitivity by detecting the output power of a local oscillation laser from the DC component of an electric signal detected by a balanced type photodiode, thereby reducing the number of components. CONSTITUTION:A transmitted signal light is made incident on an optical hybrid 4 from an optical fiber 3. Moreover, a local oscillation laser 1 is disposed in a PD module 23. The signal light and the local oscillation light are mixed by the optical hybrid 4 and its interference light 21 is emitted and made incident on a balanced type photodiode 5 to receive the light.

Title: Tape top/end detecting mechanism in recording and reproduction device
Inventor: KUSUI YOSHIO
IPC: G11B15/08
Filed: 1991-12-27
Abstract: PURPOSE:To securely operate a light receiving part without being influenced by external light and without using a shield member for preventing the external light by arranging the light receiving part in a position shielded from the external light, such as in a tape cassette, etc. CONSTITUTION:Light emitted by both light sources 11 and 12 is passed through light detecting optical paths L1 and L2 in the tape cassette 1 to reach a tip part of a light transmission body 14, whereas the light is reflected and refracted by reflecting surfaces 14c and 14d, and is received by a photodetector 13. Under the state of receiving the light emitted by the light sources 11 and 12 by the photodetector 13, when a tape is traversing the optical paths L1 and L2, the light is not received by the photodetector 13, and when a light-transmissive leader tape connected to the tip side of the tape is traversing the optical path L1, only the light emitted by the light source 11 is received by the photodetector 13, and hence the tape top is detected. Then, when a leader tape on the rear end side is traversing the optical path L2, only the light emitted by the light source 12 is received by the photodetector 13 to detect the tape end. By this method, malfunction is diminished and the need of a shield member for preventing the external light is eliminated, and hence the constitution is simplified.
