Title: Molding method of socket of porous pipe
Inventor: KOYAMA YOSHIRO
IPC: B29C57/02
Filed: 1984-09-28
Abstract: PURPOSE:To eliminate the need to repeat the hating and cooling of a mold and consequently contrive to improve the productivity by a method wherein the mold is kept as it is heated and, after molding only pipe bodies are directly cooled without forcibly cooling the remaining part. CONSTITUTION:Firstly, the end part of a porous pipe 9, which is softened by heating, is inserted onto inner molds 4,7 and 8 in case that no outer mold 10 is used. In this case, being the respective parts of the molds are properly heated in advance, the end part of the cored pipe easily clear the respective expanded diametral parts of the inner molds and formed to the form near to the mold surface. Accordingly, only the cored pipe 9 can be directly cooled and solidified by pouring cooling medium such as cooling water, compressed air or the like supplied from the cooling medium supplying pipe 13b of a pouring member 13 at this stage into the respective through holes 9a of the formed porous pipe 9 through pouring ports 13a. In this case, the inner molds 4, 7 and 8 subject not specially to cooling operations. By pulling a cylinder shaft 3 rightward, a core 4 connected through a dovetail joint with the cylinder shaft contracts diametrically so as to come off from a rubber ring groove forming part, resulting enabling to easily remove the pipe 9 from the molds.

Title: Optical communication network
Inventor: SATO KENICHI
IPC: H04B10/27
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To attain reduction of demand precision of a used wavelength by separating an optical signal wavelength multiplexed to be inputted by a wavelength branching filter, converting each optical communication node having a wavelength multiplex optical link on an input/output side into an allocation wavelength, outputting it to a specified direction by a space switch, wavelength multiplexing it by a wavelength multiplexer and outputting it. SOLUTION: With respect to optical communication nodes 1a to 1f, an optical signal wavelength multiplexed from an input side of wavelength multiplex optical links 2a to 2g connected to an input/output side respectively is separated and outputted by a wavelength branching filter. The separated optical signal is converted into a wavelength of each optical communication node to which a wavelength conversion part is allocated, is outputted in a specified direction by the space switch and is wavelength multiplexed and outputted by a wavelength multiplexer. Each optical communication node performs wavelength allocation for each one arbitrary wavelength multiplex optical link in a network according to information on a table so that a used wavelength of wavelength passes 3a to 3d becomes different.  Thus, it is possible to simplify wavelength management and wavelength allocation control, to reduce the number of used wavelengths, to reduce wavelength precision and to attain reduction of costs.

Title: Load discharging mechanism for dump truck
Inventor: NAGASAWA YOKICHI
IPC: B60P1/36
Filed: 1997-07-13
Abstract: PROBLEM TO BE SOLVED: To discharge a load in two directions by holding an upper part, of a discharging mechanism freely rotationally in the opening in the rear part, of a deck and performing selection between tight adhesion of the discharging mechanism, by which a load can be moved to the side face of a vehicle body, to the rear part, opening of the deck and release of the discharging device from the rear part opening. SOLUTION: Earth and sand or the like are let flow into a semicylindrical space formed of a cover body 44 via a space S. When oil pressure is transmitted to a hydraulic motor 58, an output shaft 59 is rotated by means of the hydraulic motor 58. The rotation of the output shaft 59 is transmitted to a small gear 60, a large gear 62, and a screw shaft 61 in this order, and consequently, a screw 64 is rotated inside a discharging mechanism 17. As the screw 64 is rotated in the internal space of the cover body 44, the earth and sand flowing into the inside of the cover body 44 via the space S are pushed sideward. For discharging the earth and sand from the back part, in the similar way to an ordinary dump truck, a shielding plate 34 is brought into tight contact with the front face of an intake frame 41 and the space S is closed.

Title: Air conditioner
Inventor: AKIYAMA TAKUO
IPC: F24F5/00
Filed: 1989-08-07
Abstract: PURPOSE:To prevent the rust and fault of parts from being generated by forming a partition plate in the casing of an outdoor unit into a dishlike configuration, providing the bottom of the casing with a drain hole, connecting the drain hole to a drain pipe and discharging water accumulated in the partition plate out of the casing. CONSTITUTION:A fuel such as petroleum or a gas is mixed with air blown by a combustion air blower 4 and burnt in a burner unit 3. The combustion air is fed to a refrigerant heater 2 and a heat exchange is conducted with a refrigerant. The air after a combustion is exhausted outside a casing from an exhaust port 5. When a heating operation is performed, since a temperature in a heat exchange chamber 6 is raised and a temperature outside the casing 1 is low, a dewing is generated on the inner wall of the casing 1 to become a water droplet, falling on the partition plate 14. The water droplet that falls on the partition plate 14 flows in a drain passage 14b to be introduced to a drain hole 14c in the deepest portion of the partition plate 14 and further falls into a drainage pipe 15 to be discharged out of the casing 1. That is, the water droplet falling on the partition plate 14 is quickly and surely discharged out of the casing 1 without penetrating into a machine chamber 7.

Abstract: PURPOSE:To measure both the biochemical oxygen demand(BOD) originated from a suspended organic substance and the BOD of a soluble organic substance of high molecular weight by providing a pretreatment device for oxidizing a sample water with using ozone in an apparatus housing CONSTITUTION:In accordance with a switching command of an output device 24, only a dilute water 7 is fed to a microbe sensor 5 through a valve 10 and a heat exchanger 20. The water enters at 29 and is discharged at 30. After the output of the sensor 5 is stabilized, the valves 8, 9, 10 are switched in a preset order and an inspection line is formed by a BOD standard solution. A BOD operating formula is stored in a memory 25. Then, simultaneously when the sensor 5 is calibrated, the sample water collected at 3 and solubilized at 2a is sent to the sensor 5 through a valve 11 and the heat exchanger 20, where the BOD value is measured. The pretreatment device 2a introduces the collected sample water to a reaction tube 31 and turns the condensed oxygen to ozone at 33 to react with the sample water at 31. Accordingly, the suspended substance is made soluble and of low molecular weight along with the dissolved organic substance. It thus becomes possible to measure a soluble organic substance of high molecular weight and improve the measuring accuracy.
