Title: Synchronizing signal detector for optical scanner
Inventor: SHIMOKAWA HIROYASU
IPC: H04N1/36
Filed: 1989-09-05
Abstract: PURPOSE:To shorten a space length reaching a photodetector and to reduce the size to reduce the size of the device by providing a synchronizing signal detection light beam transmission part which has positive power at the peripheral part of an image forming lens system, and transmitting a light beam for synchronizing signal detection through this light beam transmission part twice and then guiding the light to the photodetecter. CONSTITUTION:The photodetector 8 detects a light beam at one side end part of the range of deflection by a rotary polygon mirror 4. A light beam generating means 1 modulates the light beam with an image signal at constant timing at the time of outputting the detection signal to record the image signal from a specific position of a scanned image formation plane 9. The light beam which is guided to the photodetector 8 is transmitted through the light beam transmission part 5 for synchronizing signal detection which has the positive power of a correcting lens 5b for scanning twice and then converged on the light receiving surface of the photodetector 8. Thus, the light beam for synchronizing signal detection is transmitted twice, then guided to the photodetector 8, so the space length to the photodetector 8 can be shortened while the optical path length to the photodetector 8 is held equal to the optical path length to the scanned image formation plane 9.

Title: Piping
Inventor: HARII KIRUSHIYUNAA
IPC: F16L47/04
Filed: 1995-08-16
Abstract: PROBLEM TO BE SOLVED: To attain a sufficient level of sealing for connection between a sleeve and a coupling piece for a pipeline by injecting heated sleeve material into the collar of the coupling piece for fusing the collar and obtaining close fusion- connection with a sleeve material, and dropping the temperature for hardening. SOLUTION: The area of the exterior of a coupling piece 3 surrounded by a sleeve 4 is provided with at least one collar 5 formed out of the same plastic material as that of the sleeve 4, which is formed integrally with the coupling piece 3 and fused together with the material of the sleeve 4. The collar 5 has a large surface area relative to a narrow width, therefore slight heat of the sleeve material fused at the time of an injecting process is transmitted to the collar 5, and the collar is sufficient to fuse, thereby conducting fusion-connection with the sleeve 4 in a sealed condition. This connection also occurs between a corrugation 7 at the end part of a corrugated pipe 1 and the sleeve 4. Simultaneously, configuration is set between the sleeve 4 and a recess 6 on one side and the sleeve 4 and the corrugated pipe 1 on the other side.

Title: Self-heating type oxygen sensor
Inventor: TAKADA MASASUKE
IPC: G01N27/12
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To eliminate a need of a separate heater for heating and to enhance the responsivity of a sensor by a method wherein an oxide which is formed to be a wire-shaped or thin-film belt-shaped bidy is used as a sensor element so as to generate a hot spot. SOLUTION: A voltage is applied, from an electrode 2a and an electrode 2b, to a sensor element 1 composed of an oxide which is formed to be a wire- shaped body or a thin-film belt-shaped body, and a hot spot part 1a is formed. Then, when an oxygen partial pressure in an atmosphere is changed so as to change an oxygen content in the element 1 (oxygen diffusion), a change in an electric resistivity due to its change is detected as a signal via a processing circuit. In this case, as the oxide for the element 1, e.g. REBa2 Cu3 Oy (where RE represents one out of Y, La, Nd, Sm and the like or their mixture) is used. Thereby, oxygen as a sensor substance is diffused quickly, and the responsivity of the sensor 1 is increased.  As a result, the hot spot part 1a is coated, to be porous, with a heat-insulating material such as alumina, magnesia or the like whose thermal conductivity is small, and the hot-spot part 1a is kept at a high temperature.

Abstract: PURPOSE:To surely and safely interrupt an optical signal by stopping automatically the transmission of an optical signal from a 2nd station to a 1st station when a fault signal inserted in an overhead signal in an optical digital signal is detected. CONSTITUTION:Input interruption detection circuits 4, 9 monitor an overhead signal of a predetermined channel in an optical digital signal and sends an input interrupt signal representing the interruption of an optical fiber transmission line 11 to an optical interrupt section 6 when a fault of the overhead signal is detected. An optical transmission section 7 receiving an input interrupt signal and an optical digital input signal inserts the input interrupt signal to an overhead signal of a different channel to form the optical digital signal and the signal is sent to an optical reception section 8 in a station A via an optical fiber transmission line 12. An input interrupt detection circuit 9 receiving the optical digital signal sends the input interrupt signal to the optical interrupt section 1. Thus, the optical interrupt section 1 interrupts the optical digital signal to be sent to a station B.
