Patent JP-S63191089-A (JP)
Title: Car detector
Inventor: OISHI TSUYOSHI
IPC: E05F15/20
Filed: 1987-02-03
Abstract: PURPOSE:To dispense with a disturbance light blocking hood, by a method wherein a sensor is opposed to natural light or an irradiation light source and a car is detected on the basis of the quantity of the receiving light of said sensor. CONSTITUTION:One or plural illumination light sources or natural light is provided to the ceiling 15 of a passage 6 to perform illumination. A large number of sensors S1, S2,...S6 for detecting the brightness of the shade of a car 2 are provided to the passage 6 along an arrow 7. Each of the sensors S1-S6 is constituted by mounting a lens member to the mount hole provided to the center of a metal so as to converge light to a light receiving element. When the car 2 is present on the sensors, the quantity of the light received by the sensors becomes about 10-20% of that when there is no car 2 and, therefore, a discrimination level is set to each of the sensors. By this constitution, light can be detected not only during the running of the car 2 but also during the stoppage thereof and a hood for blocking disturbance light is not required and miniaturization of the device can be achieved without considering the space of the hood.

Filed: 1981-02-23
Abstract: PURPOSE:To improve the strength of a core and to reduce the time for molding or to reduce the amt. of addition of resins by blowing hot wind into the cavity of the core after rapping through a molding stage. CONSTITUTION:A core 4 is molded by means of the upper, lower dies 2, 3 and mandrel 8 of a molding machine 1, and the core 4 is heated with such heating means as heating burners 5 and heaters 6 by which it is thermally hardened.

IPC: F04C15/00
Filed: 1987-02-05
Abstract: PURPOSE:To prevent the deterioration in transmittance by providing a measuring gear and providing polymer leak grooves which are communicated to the sliding part with said measuring gear and to the sliding part with a driving shaft, on a bearing part which slides with the measuring gear and, further, providing a polymer discharge flow passage communicated to the leak groove and a discharge port connected to said discharge flow passage. CONSTITUTION:A polymer/monomer mixed liquid flows in from the arrow direction and is measured and conveyed downward by means of a measuring and conveying device. Gears 1a, 1b are driven by a motor via a driving shaft 4a. The driving shaft 4a is held, made slide, and rotated, by bearing parts 2a, 2b. Here, fine grooves 3 are formed on the contacting faces 19 between the side faces of the gears 1a, 1b and the bearing parts 2a, 2b, and on the bearing parts at the sliding parts with the driving shaft 4a, allowing the polymer/ monomer mixed liquid to flow through the fine grooves of the bearings, to lubricate the shaft. Thereby, the mixed liquid which finished lubricating is again returned to the fine grooves, preventing the mixed liquid as a whole from returning to a main flow, and making it flow into a polymer flow passage 6. Thereby, the mixing in of dust due to sliding can be prevented.
