Filed: 1988-04-13
Abstract: PURPOSE:To enable stable detection even in case of a large shock or long-time use by supporting a weight by a coil spring and maintaining the contact pressure of a contact at a constant value by the coil spring. CONSTITUTION:A current flows between two terminals 16 and 25 of the detector. When a door, device, equipment, or other parts where the detector is fitted are rotated or moved and vibration is transmitted to the detector, the vibration is transmitted to the weight 18 through a movable piece 13 and the coil spring 19. The weight 18 to which the vibration is transmitted begins to vibrate and the fixed contacts 14a and 15a, and movable contacts 14b and 15b of contacts 14 and 15 leave each other. Further, when the detector is moved, the weight 18 is accelerated by the movement to move relatively to a case 11 and the movable piece 13 moves to cut off the current between the two terminals 16 and 25, so that a security device connected to the detector is put in operation. Consequently, the detector withstands the large shock and long-time use and performs stable detection.

Title: Preparation of combustible gas from excrement with solar heat and cold air, and its apparatus
Inventor: KURATA SHIYOUZOU
IPC: C12P5/02
Filed: 1979-07-18
Abstract: PURPOSE: To obtain a combustible gas from an excrement, by utilizing the temperature difference between the solar heat in the daytime and the cold air in the night.  
     CONSTITUTION: An excrement is fed from a feed pipe 6 into a high-pressure vessel 1 consisting of a transparent material, and the solar heat is absorbed by the excrement in the vessel through the reffection from a sunlight reflecting plate 5 provided on the ground. The temperaure of the upper excrement increases by the absorption of the solar heat, and the lower excrement is still cool in the ground. In the daytime, the heat is transferred downward, and if necessary cold air is fed from a pipe 3. In the night, the heat is transferred in the opposite direction. During the time between the daytime and night, the heat transfer is stopped. The heat stored in the excrement increases the pressure in the excrement to ferment and decompose the substance which cannot be decomposed even in an animal body and to generate a combustible gas. If the pressure of the gas becomes high, the gas is taken out of discharge pipes 7 and 8 depending on the indication of a pressure gauge.

Title: Powder feeder fluidized bath
Inventor: YAMAZAKI TAKUO
IPC: B05C19/02
Filed: 1978-07-26
Abstract: PURPOSE: Fine powder discharge is reduced by forming fluidized bed layer inside the cylinder specifically provided.  
     CONSTITUTION: The powder feeder bath 1 is provided with the partition cylinder 2 with openings at both ends so that the bottom end 3 is slightly spaced from the bottom 4 of the feeder bath. The fluidized bed 5 is formed on the section just below the partition cylinder 2 on the feeder bath bottom 4. The inlet 6 and room 7 for air is provided beneath the bottom of the fluidized bed 5. Powder is fed outside the cylinder 2 and compressed air is fed through the air inlet 6. This causes the powder to flow into the inside the cylinder 2 through the gas X below the lower edge 3 of the partition cylinder and forms fluidized layer (a). The fluidized layer (a) varies with the size of the gap X, the powder pressure of the fixed layer B, and compressed air pressure. But, the layer (a) is caused to maintain its height because powder is fed through the gap X due to the fixed layer B pressure and the density difference between the both side layers when the layer (a) is consumed. Thus, only the minimum quantity of powder is used, resulting in reduced quantity of discharged powder.
