Filed: 1978-11-18
Abstract: PURPOSE: To aim at saving power consumption by utilizing the syphonage in a closed pipe line as to the lower floor side; and by operating a turbine for power recovery using discharging water as to the higher floor side.  
     CONSTITUTION: Water stored for air conditioning purposes is supplied to groups of heat exchangers 8, 9, etc., and after the completion of heat exchanging, the water is discharged directly into a reception tank on its 6 side through the closed pipe line as to the lower floor side, so it is due to the syphonage that only the power of mechanical loss from the pipe line and the heat exchangers 8 and so forth is supplied, and potential energy due to water storage is recovered. The discharged water on the high floor side is made to flow into the reception tank 6 through the turbine 4 for power recovery. In this case, if the speed of rotation of the turbine 4 does not reach that of a driving motor 1, the clutch of a directional differential connector 3 is disengaged. If the amount of discharge is increased, the clutch is engaged. Therefore, the rotating force produced in the turbine 4 for power recovery is carried back to the driving motor 1, so that the power is recovered.

Title: Fluid passing device
Inventor: IRIGUCHI NORIO
IPC: B04B11/06
Filed: 1979-11-05
Abstract: PURPOSE: To ensure a smooth fluid flow between the rotary body enclosing a fluid container and the stationary system in a device, without using a complex rotary driving mechanism, by using a flexible twist-resistant cable in a rigid pipe to specifically connect the rotary and stationary systems.  
     CONSTITUTION: When a continuous centrifugal separation is performed in the fluid treatment chamber 7, the rigid pipe 8 is rotated by the motor 7 around the axis 5. The hollow cable 11 housed in the pipe 8 is free to slide in the pipe 8 and fixed to the lid 8; so the cable receives a twisting force from the pipe 8. But, because of the cable material being twist-resistant, the cable itself turn in the pipe 8 rather than being twisted. As a result, the part of the rigid pipe 13 at the end of the cable 11 makes two turns around the axis 5 in the same direction as the pipe 8 while the pipe 8 makes one turn. Thus the cable 11 is not twisted during rotation and therefore the internal flexible fine pipes 10 are not twisted. The cable 11 rotates the rotary body 4 enclosing the chamber 7 in the same direction at a speed twice that of the pipe 8, so that centrifugal separation is conducted in the chamber 7.

Inventor: YAHAGI MASAHISA
IPC: B29K21/00
Filed: 1985-06-28
Abstract: PURPOSE:To enable to make an extent of supervulcanization at a position other than the latest vulcanizing point small and to curtail overall vulcanizing time, by vulcanizing a raw tire after the raw tire has been formed by allotting treat rubber in a plurality of layers which is the more it becomes inward, the faster a vulcanizing speed becomes. CONSTITUTION:The whole thickness B of a tread part 2 is larger than the other part, for example, the whole thickness C of a slide wall part 3 by a large margin. Moreover, as an inner tread rubber 8 is positioned at the center of the direction of a thickness of the thick tread part 2, an increase of the temperature is slower drastically than that of the other part. As a vulcanizing speed of the inner layer tread rubber 8 is made faster than the vulcanizing speed of outer layer tread rubber 9, time required until the inner layer tread rubber 8 becomes the most suitable degree of vulcanization is about indentical with that of the other part or approaches to that. As basic ingredients of both the rubber 8, 9 are identical with each other, physical propeties of both the rubber 8, 9 after vulcanization, for erample, resistance to wear (Shore A handness) becomes practically identical with each other; consequently, generation of the situation such as separation is prevented.

Title: Propagation burner
Inventor: KIMURA JUNICHI
IPC: F23N5/02
Filed: 1988-06-09
Abstract: PURPOSE:To upgrade combustion efficiency by installing an arbitrary change over means which can switch over to a high pressure mixed air when there is aflame on a gas supply side and change over to allow pressure mixed air when there is a flame on a gas discharge side based on aflame detection signal transmitted from a flame detector and propagating the flames going and returning without extinguishing the flames directly. CONSTITUTION:During starting a low pressure side change over means V2 is opened and a premixed low pressure air is supplied to a mixing chamber 3 from a mixed air nozzle 6. When a gas supply side flame detector F1 detects a flame flow, a high pressure side change over means V1 is opened to premix the air through the mixing air nozzle 6 and supply high pressure mixed gas to the mixing air chamber 3. When the high pressure mixed gas, after it is sufficiently mixed, is supplied to a straight pipe-shaped combustion chamber 1 by way of a narrow section 2, the gas flows from the upper stream side to the lower stream side inside the straight pipe-shaped combustion chamber 1 and performs flame propagation combustion motion while going on. When a gas discharge side flame detector F2 detects a flame stream, a low pressure side solenoid valve V2 is adapted to open, and supply the low pressure gas into the straight pipe-shaped combustion chamber 1, thereby performing the flame propagation combustion motion going on. An ignition heat source 4 is only required during starting. When the starting is over, the going and returning propagation combustion motion is carried out in automatic mode, thereby upgrading the combustion efficiency.
