Title: Camera
Inventor: AOKI NOBUHIRO
IPC: G03B17/08
Filed: 1999-06-11
Abstract: PROBLEM TO BE SOLVED: To provide a camera capable of preventing water from infiltrating into the inside of a camera body with a simple structure and keeping the internal pressure of the camera body equal to ambient pressure by providing an air chamber having larger cross-sectional area than a ventilation path through which the inside and the outside of the camera body communicate with each other in the middle of the ventilation path, recovering the water infiltrating into the ventilation path through the air chamber and discharging the water to the outside. SOLUTION: The air chamber 32 is provided in the middle of the ventilation path 26 through which the inside and the outside of the camera body 12 communicate with each other. The chamber 32 is formed so that its cross-sectional area may be larger than that of the path 26 and formed to open to the outside of the camera body 12. The opening part 32A of the chamber 32 is covered with a drain valve 34 having larger area than the opening part 32A from the outside of the camera body 12. Waterdrops infiltrating into the path 26 are recovered in the chamber 32 and discharged to the outside through the valve 34.

Title: Gate opening controller
Inventor: FUKAGAWA TSUMORU
IPC: E02B7/40
Filed: 1978-12-29
Abstract: PURPOSE: To enable an overflow amount of water to be automatically controlled according to a water level of a reservoir, by moving a body, which rotates in accordance with rising an falling of a float of a reservoir, in synchronism with opening and closing of a gate.  
     CONSTITUTION: When a float 6 is raised as a result of a water level 7 at the upstream side rising, the movement of a rope 8 causes rotating of a functioning object 10, a valve poppet 20 parting from a valve port. This causes an oil in a cylinder 3 to return to an oil tank 17. Thus, a gate 1 falls down gradually by dint of the water pressure, and thereby water at the upstream side overflows the upper end of the gate 1. When the gate 1 starts to fall down, a sprocket 23 and a male screw 13 turn through the working of an endless chain 24, the functioning object 10 moving in the opposite direction to a mechanical valve 15. This causes the valve poppet 20 to close the valve port. As a result, the oil in the cylinder 3 stops flowing out, which results in stopping the gate 1 at a present position. In the case of the gate 1 being raised from the fallen position thereof, the oil is fed into the cylinder 3 through the working of a hydraulic pump 27.

Title: Manufacture of al based rare-earth magnet
Inventor: YANAGAWA MASAHIRO
IPC: C22C33/00
Filed: 1987-07-02
Abstract: PURPOSE:To enhance the thermal resistance, to enhance a possibility of plasticity processing by a forging process, to enhance the conductivity, to reduce a cost by improving the handling convenience and the degree of freedom for designing by using an Al powder or an Al alloy powder as a coupling agent. CONSTITUTION:A rare-earth magnet powder at 10-80volume% is added to an Al powder or an Al alloy powder; this mixture is shaped preliminarily by a cold pressing process. In addition, the mixture is shaped by a hot pressing process; it is solidified to form a shaped substance; after that, it is magnetized. The rare-earth magnet powder refers to a powder of, e.g., a samariumcobalt magnet (composed of Sm1Co5 and SM2Co17) and a neodymium-iron-boron magnet (composed of Nd15Fe77B8); these are used by appropriately mixing one kind or two or more kinds. During the cold pressin process, if the mixture which has been wet-mixed in a Freon-based low-melting solvent is pressed in a magnetic field, the magnet powder is oriented; by this setup, an Al based rare-earth magnet whose anisotropy is excellent can be obtained. If a mixing ratio of the rare-earth magnet powder is less than 10%, it is difficult that this mixture functions substantially as a magnet. If the ratio exceeds 80%, a coupling force via Al is lost; the mixture cannot be solidified and shaped; a meaning of light weight is lost.
