Abstract: PROBLEM TO BE SOLVED: To provide a method of reserving a natural gas in an absorption type natural gas storage tank, which can restrain adsorbent from raising its temperature when the natural gas is reserved in the storage tank. SOLUTION: A liquefied natural gas is fed into an adsorption type natural gas storage tank 12 mounted on a natural gas engine automobile and incorporated therein with adsorbent, from an LNG tank 10. In this phase, the quantity of a liquefied natural gas fed into the storage tank 12 is monitored by a pressure sensor 16. When the pressure detected by the pressure sensor 16 reaches a predetermined value, a shut-off valve 18 is closed so as to stop the supply of the liquefied natural gas. Since the temperature of the liquefied gas is low, the temperature rise of the adsorbent caused by heat of adsorption when the natural gas being adsorbed to the adsorbent in the tank 12, can be held to be low, thereby it is possible to restrain the adsorbed amount from lowering.

Abstract: PROBLEM TO BE SOLVED: To sustain insulating characteristics stably while resisting against plastic machining and magnetic annealing by forming an insulating film on the surface of a magnetic metal or alloy plate by sol-get method using a solution of metal alkoxide shown by a specific formula. SOLUTION: After being applied to a magnetic metal plate, an insulating film is subjected to plastic machining and magnetic annealing to produce an electromagnetic core. The insulating film is formed by sol-get method using a solution of metal alkoxide shown by a formula M(OR)n [M: metal, R: alkyl group, n: natural number], where M, R and n are not limited so long as a stabilized insulating film can be formed by sol-gel method. Furthermore, ceramic particles being dispersed into the metal alkoxide solution is not limited and viscosity of the solution is increased by adding an insulating viscous substance.

Abstract: PROBLEM TO BE SOLVED: To provide a core member and an armature member for a solenoid actuator having structure realizing a small loss. SOLUTION: Planar members 12 having at least one easy direction of magnetization are laminated semi-elliptically or semicircularly with the easy direction of magnetization being set in the circumferential direction. Two semielliptical or semicircular laminates are bonded contiguously while abutting the outer circumferential faces such that the cut face will be coplanar. The laminates are then disposed oppositely and a coil is set in one recess to produce a core member 10 while a shaft 20 is fixed to the other recess thus producing an armature member 18. Since lines of magnetic force 16 generated from the coil 14 are aligned constantly with the easy direction of magnetization of the planer member 12, the iron loss of a solenoid actuator can be reduced significantly.

Abstract: PURPOSE: To takes out feedable electric power maximally from an alternator when electric power is fed only from the alternator to a plurality of on-vehicle electric heating type catalysts. CONSTITUTION: An electric power feeder is provided with an alternator 10 driven by means of a driving source in a vehicle so as to generate electricity, a battery charging circuit 14 included in the alternator 10, and a battery 8 which can be charged/discharged. Changeover switches SW1-SW3 are arranged between a stator coil 11 in the alternator 10 and the battery charging circuit 14, and output of the stator coil 11 is fed to output terminals 16, 17 arranged in the alternator 10 when the battery 8 is not charged, while the rotor coil 12 is connected to the battery 8. Two electric heating type catalysts 3A, 3B are connected to the output terminals 16, 17 in series while their outer cylinders are grounded. As a result, electric power is directly fed from the alternator 10 when the electric heating type catalysts 3A, 3B are heated, so that ability of the alternator 10 can be used maximally.
