Title: Detector of crossing and access
Inventor: KITANI HIROSHI
IPC: G08B13/187
Filed: 1990-05-07
Abstract: PURPOSE:To keep receiving sensitivity constant by receiving a far ends combining signal by transmitting signal, and by detecting crossing movement and access of a moving object by variance of the received signal when the moving object crosses or approaches an open type coaxial cable. CONSTITUTION:A signal that is sent from a transmitter 3 provided at an end of one of two open type coaxial cables 1 and 2, is detected by the aforementioned transmitter 3 on the cable and a transmitter 11 provided at a farther side end of the cable, via the other cable. The received signal by this receiver 11 has the same transmission loss even if it is propagated from one cable to the other one at any point in a longitudinal direction of a detector, since passing lengths until being received through the open type coaxial cables 1 and 2 are quite the same in both cases, and therefore there exists rather small influence caused by the transmission loss.

The positive input of the cmparator 23 is connected to a switch SW25 which performs the switching between the potential VR and the earth potential. Then an output signal is fed back to a negative input via a switch SW21. The SW21 is closed with the SW24 and SW25 connected to the signal Vin and the earth, respectively. Then the SW21 is opened, and the SW24 is earthed. The signal Vin is sampled with the capacity 22, and the polarity of the Vin is decided. According to the positive or negative polarity of the Vin, the SW25 is connected to the potential VR or the earth. Then a part of the SW24 is earthed with the other part connected to the VR. The SW21 is closed and then opened, and the comparator 23 performs a sequential comparison. Thus the offset is eliminated for the A/D conversion.

Abstract: PURPOSE:To obtain an optical fiber preform having excellent characteristics, preventing the formation of bubbles at the glass interface and the intrusion of moisture into the preform, by preheating a glass rod with a flame containing chlorine or its compound, and depositing a glass layer to the circumference. CONSTITUTION:The glass rod 6 ascending slowly under rotation is preheated at a high temperature by a flame containing chlorine (compound) which does not form a glass raw material, e.g. SOCl2, etc. using a preheating burner 3. Glass soot formed by the vapor-phase reaction, i.e. flame hydrolysis reaction by the glass-forming burners 4, 5 is deposited to the outer circumference of the preheated glass rod 6 to form a porous glass layer 7. Since the glass rod 6 is preheated, the glass soot can be deposited firmly to the rod. Thereafter, the glass layer 7 is converted to a transparent glass layer by the thermal treatment in an electrical furnace (1,400 deg.C) in a mixed atmosphere consisting of e.g. H and a small amount of SOCl2.

Abstract: PURPOSE:To enable a burr to be removed in a short time from a core without flawing its surface while enable a dust by static electricity to be prevented, by blowing an abrasive material, in which a thin bar of polyurethane rubber is finely cut, to be injected or dropped on the surface of the shell core. CONSTITUTION:An abrasive material of urethane rubber is formed by cutting a bar of urethane rubber into about 3mm. length, and if the abrasive material is blown by air to the surface of a shell core generating a burr, the abrasive material, having suitable hardness and mass, breaks only the burr generated in the shell core to be removed by the collision of the abrasive material without causing the generation of a blow flaw on the surface. Further a size of the bar of urethane rubber is classified by an extent of the burr, while hardness of the bar of urethane rubber is selected in accordance with a quality of the core. In this way, the abrasive material, providing low electrification of static electricity because of urethane rubber, prevents a dust or the like from adhering to the abrasive material while the surface of the core from becoming dirty by adhesion of the dust.

Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To obtain an inspection method and apparatus capable of automatically inspecting the surface treated state, component and quality such as thickness or the like of a polymeric molded article over the entire surface thereof. SOLUTION: The unpolarized light emitted from a lamp 3 is linearly polarized in the specific direction by a polarization plate 4 provided in parallel to a film 2 to be incident on the film 2. The transmitted light from the film 2 is split into a P-polarized component and an S-polarized component by the beam splitter of a polarization camera and both components are respectively detected by CCD image sensors 8,9. A CPU 12a compares the signal value of the P- polarized component with the signal value of the S-polarized component to find a polarized component ratio R corresponding to an angle of rotation. Since the angle of rotation changes corresponding to find a surface treated state, the polarized component ratio R is compared with the standard value of the film to which proper surface treatment is applied to enable the inspection of the surface treated state of the film.
