IPC: B01D53/22
Filed: 1988-05-18
Abstract: PURPOSE: To improve selective permeability of a gas sepn. membrane by imparting a reactive monomer material of a specific mol.wt. to the surface of the gas sepn. membrane and polymerizing the same. CONSTITUTION: The outer surface of, for example, an asymmetrical polyamide hollow fiber membrane is brought into contact with a soln. prepd. by diluting the reactive monomer material, such as 2,4-toluene diisocyanate, of the mol.wt. of <1000 with a nonreactive liquid of a hydrocarbon halide. The monomer material is then reacted to form a polymer and thereafter, the membrane is dried. he defect and drawback of the membrane are sealed by this treatment and the selective permeability of the membrane relating to >=2 kinds of gases, such as helium and gaseous nitrogen, is improved. Consequently, the productivity of the gases is enhanced.

Title: Temperature controller for eddy current coil in eddy current brake
Inventor: OBA MITSUYOSHI
IPC: B60L7/28
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To provide a temperature controller for preventing an increase in temperature above a given allowable level at an eddy current generating coil in an eddy current brake. SOLUTION: In a temperature controller, temperatures at eddy current generating coils 51a to 58a are detected by a coil temperature sensor 11. When the temperature of the eddy current generating coils 51a to 58a detected by the coil temperature sensor 11 is increased above a given allowable level, the quantity in continuity to the eddy current generating coils 51a to 58a is reduced under control of a continuity limiting device 12. As a result, a calorific value of the eddy current generating coils 51a to 58a can be reduced, thereby preventing overheat of the eddy current generating coils 51a to 58a.

IPC: B01J29/068
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To control the growth of noble metal particles by a method in which when a specified range in wt.% of noble metals are carried on the whole zeolite particles, the quantity of the noble metals carried within a range up to 2 nm from the surfaces of the zeolite particles is set up at 1.0 atomic percent or below.

Title: Method and apparatus for detecting gas by semiconductor gas-detecting element
Inventor: OKINAGA KAZUO
IPC: G01N27/12
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for detecting by a semiconductor gas-detecting element, whereby a gas can be detected almost continuously. SOLUTION: A microcomputer 3 alternately sets the power supply to a heater 2 of a semiconductor gas-detecting element 1 to a high-temperature period and a low-temperature period with a predetermined cycle, and samples a resistance value of a gas-sensitive body of the semiconductor gas-detecting element 1 with a cycle of one second in each term. For each sampling timing, the microcomputer 3 subtracts a resistance value Rsh(t) or RsL(t) of the gas-sensitive body detected at the timing from a reference value Rsmh0(t) or RsmL0(t) which are set, correspondingly to the timing and divides the resistance value by a difference Rsmh0(t) or removed by Rsmh0(t), thereby obtaining a change rate Sh or SL. Whether or not the change rate Sh or SL exceeds a CH4 determining value V1 or CO determining value V2 is determined.  When the change rate exceeds the determined value, a buzzer 6 is sounded and warning is issued.
