Title: Pipeline structure for heat accumulating tank
Inventor: HASHIMOTO SHINICHI
IPC: F28D20/00
Filed: 1986-02-21
Abstract: PURPOSE:To obtain the pipeline structure for a heat accumulating tank, which is easy in laying and permitted to determine the place of installation freely, by a method wherein a hopper part, expanded from the base end to the tip end thereof, and a pipeline, connected to the root of the hopper part, are attached to a predetermined position in the heat accumulating tank while a temperature layer is formed in the heat accumulating tank by heat accumulating medium. CONSTITUTION:Hot-water is sucked from a second hopper 13b by the operation of a pump 9 and flows to a direction, shown by arrows C, through a pipeline 14 into an air-conditioning unit 10 to effect room heating operation. Then, the heat of the hot-water is deprived by the room heating operation and becomes water cooled in some degree, thereafter, flows into a first hopper 13a through the pipeline 14 and flows out from the blow-off and suction port 16 of the first hopper 13a to the lower position of an accommodation chamber 18. The blow-off of the cooled water is effected quietly comparatively, therefore, a temperature layer, consisting of a high-temperature hot-water layer located in the upper part of the temperature layer, and a low- temperature hot-water layer, located at the lower part of the temperature layer, are formed in the accommodation chamber 18.

Title: Acceleration detector
Inventor: YAMAMOTO TERUKAZU
IPC: G01P15/135
Filed: 1995-01-31
Abstract: PURPOSE: To increase DWT by providing a ring-shaped magnet, which has a central axis in common with a moving magnet and has polarity of the same direction, on the periphery of a central part of a lead switch. CONSTITUTION: Since a fixed magnet 6 and a moving magnet 2 of which polarity is in the same direction and which is supported by a coil spring 3 cancel each other's magnetic forces, a contact point of a lead switch 1 is in the released state. When acceleration is applied there, the moving magnet 23 starts moving, so that the balance of a magnetic field, which has been conceled each other at initial condition, is thrown off, and the contact point of the lead switch 1 is closed. While the acceleration continues, the moving magnet 2 continues to move, and stops at a stopper 7. When the application of acceleration is stopped, the magnet 2 starts returning to the initial position due to resiliency of the coil spring 3, and then, at the position where the magnetic fields of the fixed and moving magnets 6 and 2 negate each other, the contact point of the switch 1 is diconnected.  As a result, Dwell Time(DWT) is increased.

Title: Purification of caprolactam
Inventor: YARINO TATSUO
IPC: C07D223/10
Filed: 1983-03-08
Abstract: PURPOSE:To obtain a highly pure refined caprolactam, at a low cost, by distilling crude caprolactam, and passing the molten caprolactam through a cation exchange material. CONSTITUTION:Crude caprolactam is distilled to remove the impurities which can be removed by distillation. The distillation is preferably carried out under reduced pressure at a lowest possible temperature to prevent the decomposition of caprolactam, generally at about 130 deg.C under a vacuum of 5Torr. The distilled caprolactam is passed in a molten state through a cation exchange material, especially a strongly acidic cation exchange material such as sulfonated polystyrene. A high-purity refined caprolactam can be obtained by this process in an extremely high ion exchange performance. The whole treatment from the distillation to the ion exchange treatment is preferably carried out in the absence of oxygen.

Abstract: PURPOSE: To enable to prevent mis-detection, by greatly reducing (about 1/3) the hardware, through the exclusive logical sum for each latch to detect the error of operation for the data transfer control system.  
     CONSTITUTION: In the input and output selection latches 8, 10 and the mark latches 14, 15, when one is inverted, then another corresponding to it is also inverted. The data transfer control system error check circuit CKT consists of the exclusive logical sum circuit 16 and the error latch 17. When the initial value of the latches 8, 10, 14, 15 is taken as "0", the value of the exclusive logical sum 16 of each latch 8, 10, 14, 15 is always "0", as far as the system normally operates, excepting transient phenomenon, and accordingly, the latch 17 is "0". Next, if there is wrong sequence to the latches 8, 10, 14, 15, the output of the circuit 16 is "1" and accordingly, the latch 17 is "1". The error of the system is informed through the error line 25.
