Title: Method for regenerating pressure-swinging adsorber in air liquefying separator
Inventor: HONDA HIDEYUKI
IPC: F25J3/08
Filed: 1986-05-15
Abstract: PURPOSE:To increase the proportion of the regenerated gas and to reduce the operating pressure by providing >=2 groups of pressure-swinging adsorbers, and supplying the waste gas and the gaseous product separated and generated at a low-temp. separation part exclusively into the respective adsorber groups. CONSTITUTION:The air introduced from a pipe 1 is sent to pipes 3 and 3a through a compressor 2, and sent to the pressure-swinging adsorbers 5a and 21a of the adsorber groups 5 and 21. The water and CO2 are adsorbed in the adsorbers, and the air is sent to the low-temp. separation part 8 through pipes 7 and 23, liquefied, rectified, and separated therein to obtain O2 and waste gas. The gaseous product of O2 is discharged from a pipe 9, and the waste gas is discharged from a pipe 10. The O2 is exclusively sent to the adsorber 21b, and the waste gas is exclusively sent to the adsorber 5b. The adsorbers 5b and 21b are regenerated, the O2 is taken out as the gaseous product from a pipe 26, and the waste gas is discharged through a pipe 13. Adsorption and regeneration are periodically carried out by operating the change-over valves.

Filed: 1979-08-31
Abstract: PURPOSE:To fix securely a blind plug in the multitubular type heat exchanger by a method wherein when an open end of a heat transfer tube is to be shut by the blind plug because of occurrence of a fine pore thereon, an axial connecting hole is provided on the blind plug which is to be installed later and is shut after this blind plug is fixed. CONSTITUTION:In repairing the heat transfer tube 3 having a pore 5 which occurred on the intermediate portion of the tube, first, a tapered blind plug 6 is struck into an open end of the heat transfer tube 3 on one side of an exposed fixed tube plate 4. Then, another blind plug 7 is struck into the other open end. This blind plug 7 has the same taper shape as the blind plug 6 and is provided with an axial connecting hole 8 and a female screw 9 is cut on the inner surface of the connecting hole 8. Since the connecting hole 8 is provided, this blind plug 7 can be struck securely, keeping the before-mentioned blind plug 6 from removing on account of increase of the inner pressure of the tube caused when the plug 6 is struck. After that, the connecting hole 8 is stopped with a setscrew 10.

Title: Solder paste for precoating
Inventor: ASANO SHOZO
IPC: H05K3/34
Filed: 1995-04-14
Abstract: PURPOSE: To make it possible to remove the solder balls generated at the tame of soldering by kneading a pasty flux contg. a specific ratio of solid content and viscosity control agent which evaporates at a soldering temp. with powder solder. CONSTITUTION: This solder paste for precoating is prepd. by kneading pasty flux contg. 5 to 40wt.% solid content and the viscosity control agent which is solid at ordinary temp. and evaporates at the soldering temp. and the powder solder. The solid content is colophonium, chitin agent, activator, etc. Solderability is poor if the solid content in the flux is lower than 5wt.%. The flux flows in a large amt. and the formation of bridges and the fixation of solder microballs are resulted if the solid content is added to the flux in excess of 40wt.%. On the other hand, printability is poor if the solid content is not higher than 40wt.%. Then, the formation of bridging is prevented and the removal of the solder microballs is facilitated by adding the solid content to the flux at a lower ratio. The improvement in the printability is made possible by compensating the low ratio of the solid content with the viscosity control agent.

Abstract: PURPOSE: To eliminate use of a limit switch and stop the cage of a dust removing machine at any desired position by setting the wind-down target position of the cage depending upon the water level sensing value and the depth from the water surface, sensing and accumulating the wind-down distance from the rotating angle of a drum, and comparing the obtained value with the set value and conducting necessary control. CONSTITUTION: A dust removing machine has a cage 3 to collect floating objects from the water surface of a dam, and the distance necessary for winding down the cage 3 to the sinking stop target position is calculated by a calculator 211 in a position control circuit 21 using a constant which is determined by the sensing value of a water level sensor 23 and the structure of dam, and the obtained value is set in a setting device 22. The cage 3 is wound down along the dam wall 1 by a wind-up/-down drum 4 and a drive motor 5, and the wind-down distance is sensed by a pulse pickup 25 in the form of pulses corresponding to the rotating angle of the drum 4, followed by calculation by a cumulator 24, and the obtained value is fed to a comparator 212 to be compared with the set value.  If the wind-down distance is identical to the set value, the drive motor 5 is stopped, and the cage 3 is opened to take in floating objects, and winding-up is made to the stop position followed by a collection process.

Title: Core position detector for wound-shaft part such as coil
Inventor: HORIUCHI KAZUO
IPC: G01B11/00
Filed: 1988-05-10
Abstract: PURPOSE:To enable accurate detection of a position of a core, by operating multiple sets of photoelectric switches for detecting the core by one set sequentially to detect the position of the core with the repetition of the operation. CONSTITUTION:Opening-closing operation is repeated with make contacts T1-T2 at a specified time interval to emit light at a specified time interval from projectors PH'1-PH'4. At time t1 and t2, even when the contacts T1 and T2 are turned ON, light receivers PH''1 and PH''2 fail to be turned ON and none of relay coils X1 and X2 is energized when a core does not exist at the position of photoelectric switch. Now at time t3, the contact T3 is closed to emit light with a projector PH'3 and when light from the projector PH'3 is intercepted by a core, the light receiver PH''1 is turned ON while the contact T1 is not closed, hence energizing none of the coil X1. At time t4, when the contact T1 is closed, the light receiver PH''1 is turned ON and current flows through the coil X1 to excite the coil X1. Thus, it is displayed that the core is located at a position where the core intercepts an upper photoelectric switch.
