IPC: G01N21/17
Filed: 1994-03-25
Abstract: PURPOSE:To perform an accurate and positive sensing of a foreign material at a surface to be detected without being influenced by disturbance light and to remove the foreign material. CONSTITUTION:Light projected from an LED 3 is incident in such a way that its incident angle may become a value near a Brewster's angle against an item 2 to be detected. The item to be detected which is comprised of transparent material such as glass reflects only an s-polarized light component under a state in which foreign substances such as water droplets, frosts or the like are not adhered to the surface. A polarization beam splitter 4 reflects the s- polarized light component, and incidents it to a light receiving element 5. In the case that foreign materials such as water droplets and frosts are adhered to the surface of the item 2 to be detected, light reflected by the item 2 to be detected includes not only the s-polarized light component but also a p- polarized light component. The polarization beam splitter 4 passes the p- polarized light component and incidents the light into the light receiving element 6. It is possible to judge the adhering state of water droplets and frosts at the surface of the item 2 to be detected in reference to a ratio of output between the light receiving elements 5 and 6.

Title: Special playback system for vtr
Inventor: MATSUOKA HIDEO
IPC: H04N5/93
Filed: 1987-03-13
Abstract: PURPOSE:To prevent a noise from appearing on a screen even when a tape speed is increased by making the rotating speed of a head drum faster than a normal rotating speed at the time of high-speed reproduction, and extending the time base of a video signal of a field selected correspondingly to the rotating speed of the head drum and obtaining a video signal of normal frequency. CONSTITUTION:The rotating speed of the head drum 1 at the time of cue reproduction and review reproduction is set double as fast as the normal speed. Thus, the rotating speed of the head drum is made double, and then modulated video signal outputted from rotary heads 2 and 2' through preamplifiers 18 and 18' are double in frequency and their time bases are shortened to 1/2. A video signal processing circuit 20 demodulates the modulated video signal as a luminance signal Y and a color signal C separately and extends the time base by twice to obtain a continuous signal of normal frequency. Consequently, even when the playback speed of a helical scan VTR at the time of special reproduction such as cue or review reproduction is increased, there is neither a noise band nor skew generated or at least reduced.

Filed: 1990-03-09
Abstract: PURPOSE:To provide long-term stability and chlorine ion selectivity by using a chlorine ion sensitive film constituted of a quaternary ammonium salt having a silane coupling group and long chain alkyl group as an ion sensitive film. CONSTITUTION:The chlorine ion sensitive film is provided on a chromium electrode 2 for the separating gate of a chlorine ion sensitive chip 5. The chlorine ion sensitive film constituted of the quaternary ammonium salt having the silane coupling group and long chain alkyl group is used as this ion sensitive film 2. A methoxysilyl group, etc., are known to react with a hydroxyl group existing naturally as a hydroxide on the surface of a metallic electrode and the quaternary ammonium salt having the silane coupling group can be fixed in the form of covalent bonding to the surface of the metallic electrode by this reaction. The elution of the quaternary ammonium salt into a specimen is prevented in this way and the ion sensitive film 2 is securely fixed to the electrode. Since the quaternary ammonium salt is used, the selectivity to Br<->, I<->m etc. of Cl<-> is enhanced.
