Patent JP-H0335422-A (JP)
Title: Production of magnetic recording medium
Inventor: TAMAI HIDEKI
IPC: G11B5/851
Filed: 1989-06-30
Abstract: PURPOSE:To improve reproduction output and recording density by forming a recording film by discharge in an Ar gas containing a little amt. of additive gas and controlling the partial pressure of the additive gas to be high in the beginning stage of film formation and to be low near the end of film formation in order to obtain the perpendicular coercive force of the film varying from higher near the surface to low with the depth of the film. CONSTITUTION:The perpendicular magnetized anisotropy film is formed on a substrate by sputtering, by discharging in an Ar gas with a little amt. of additive gas (oxygen, nitrogen). The partial pressure of the additive gas is controlled to be high at the beginning stage of film formation and low at the end. Thereby, the obtd. recording medium has higher coercive force in the perpendicular direction near the surface and lower in the depth direction. Thus, recording by use of a magnetic head can be performed enough to deep part of the medium.
Patent JP-H0833192-A (JP)
Title: Relay controller
Inventor: SATO KEIKICHI
IPC: H02H7/045
Filed: 1994-07-21
Abstract: PURPOSE:To prevent an unneeded operation caused by the residual of a DC component contained in an excitation inrush current in a current transformer by controlling a relay means based on the zero-phase current detection means on the load side, the output of a differential current detection means, and the output of a current detection means provided on the load side. CONSTITUTION:The output of a current transformer 3 and that of a current transformer 4 are inputted to a differential current detection circuit 6 to obtain a differential current. The differential current is inputted to a 2F-Lock element 8 and is also fed to a DIF element 7 for judging the internal failure of the current transformer. When a circuit breaker 16 is switched many times for magnetizing bias or saturating the current transformer 4, a grounding overcurrent relay 12 operates and a grounding overcurrent relay 14 does not operate. Therefore, '1' is outputted from an AND circuit 22 and the output becomes '0' regardless of the output of the 2F-Lock element 8 when performing a NOT OR with the output of the 2F-Lock element 8, thus disabling a relay controller 11 as well as a protection circuit 15.

Title: Modification of low-quality coal
Inventor: MUROI KATSUMI
IPC: C10L5/32
Filed: 1983-09-16
Abstract: PURPOSE:Heat-treated low-quality coal is coated with tar and simultaneously the environmentally polluting substances in water formed in heat treatment are absorbed on the activated carbon obtained from the low-quality coal whereby a large amount of low-quality coal is modified without environmental pollution. CONSTITUTION:Low-quality coal is heat treated usually at 250-450 deg.C to remove water in the coal and decompose oxygen-containing functional groups whereby the coal is made hydrophobic, then the coal is allowed to adsorb tar and coated with the tar which is formed during the heat treatment. At the same time, the water resulting from the pyrolysis is treated with activated coal from the low- quality coal to remove substances causing environmental pollution. EFFECT:The modification prevents the product from flying off dust and increases calorific value.

Title: Method and device for testing water leak in various water tanks
Inventor: HORINOUCHI SHIGERU
IPC: G01M3/04
Filed: 1990-06-26
Abstract: PURPOSE:To save water and to speedily conduct a water leak test by forming a water film while sprinkling and circulating a small amount of water, reservoired in a tank body, on the inner peripheral surface, and detecting a water leak place while sending compressed air into the tank body and holding the tank body in the pressure state. CONSTITUTION:The tank body 12 is formed a completely sealed type which has only one or plural intake outlets 14 formed in the top surface as main openings. Namely, while the intake outlets 14 of the tank body 12 are sealed and the water M reservoired in part of the tank body 12 is sprinkled and circulated on the inner peripheral surface of the tank body 12, the water film W is formed on the inner peripheral surface of the tank body 12 and the compressed air is sent into the tank body 12 to detect the water leak place from the wetting of the water of the water film W to the outer surface of the tank body 12. Consequently, the reservoired water which is required for the water leak test is small in amount and the cost is low; and the need for trouble is eliminated and the water leak test can speedily be conducted.

Title: Power steering controller
Inventor: OKAMOTO OKIMICHI
IPC: B62D6/02
Filed: 1984-08-15
Abstract: PURPOSE:To aim at simplification in a power steering structure and the promotion of its low-unit cost of production, by making the opening of a solenoid- operated type flow valve variably controllable in a direct manner, according to a car speed or the like. CONSTITUTION:Such a voltage as being varied according to a car speed is inputted from a car speed sensor 8 to the voltage input side of a voltage-to-current conversion circuit 7 as an input voltage Vi, and an output current Io commensurate to that is fed to a solenoid 6 as a driving current. Opening of a solenoid- operated type flow control valve 5 depends upon driving force of the solenoid 6, and the driving force of this solenoid 6 depends upon the size of the driving current Io to be fed to the solenoid 6. Therefore, this driving current Io is controlled for negative feedback according to the input voltage Vi out of the car speed sensor 8 whereby steering assist force of a power steering is variably controllable according to the input voltage Vi, namely, the car speed.

Title: Cooling apparatus
Inventor: MATSUDA NORIMOTO
IPC: F25B7/00
Filed: 1990-06-27
Abstract: PURPOSE:To extend the range in which the temperature of a cooled body can be set by a method wherein between the last stage of a refrigerant line for a refrigerant with the lowest boiling point and a cooled body, a plurality of secondary refrigerant circulating lines, each of which contains a secondary refrigerant differing in boiling point from another, are provided in parallel. CONSTITUTION:Mixed refrigerant gas discharged by the compressor 101 undergoes repetitive gas-liquid separation; after undergoing condensation at a heat exchanger 113, a gaseous phase refrigerant with the lowest boiling point undergoes expansion under reduced pressure at a capillary tube 115, hence assuming two phases of gas and liquid, and then at a cooling device 140 becomes vaporized in part by absorption of heat from the secondary refrigerant in a brine line 141, and at a cooling device 150 it absorbs heat from the secondary refrigerant in a brine line 151; after passing through the heat exchangers successively the refrigerant returns to the compressor in the form of low pressure gas at normal temperature. The secondary refrigerant used in each of the brine lines 141, 151 differs in boiling point from the secondary refrigerant in the other brine line. Therefore there is a difference in temperature between the cooling coils 143, 153. And by adjusting the openings of flow-regulating valves V1, V2, changes of the temperature of a cooled body 123 based on the tempera ture difference can be effected in a wide range.

Title: Automatic plate thickness controlling method of cold rolling mill
Inventor: MAJIMA KANEYOSHI
IPC: B21B1/22
Filed: 1984-08-17
Abstract: PURPOSE:To improve the quality of a product by switching a control system of a designated side to a control system of a non-designated side, when the control system of a designated manipulated variable has reached a limited value, and also varying a limited value of a variable limiter of the designated side. CONSTITUTION:When reversible limiters 10', 30' reach control limited values G1, G2, control signals S1, S2 are outputted, and also timers 14, 34 are started, and measure the time of integral time constants TT, TV of a tension and a speed, respectively. Subsequently, the control limited values G1, G2 are reduced linearly for a prescribed time, and thereafter, returned linearly to its original level. In this case, an output of the reversible limiter 10' is in a saturated state, therefore, when the limit G1 is reduced, the output of the limiter 10' also follows it and becomes small. According to this method, a speed AGC system operates without interfering with a tension AGC system, and works so that a deviation of a plate thickness of the delivery becomes zero. Accordingly, the plate thickness accuracy is stabilized, and the quality of a product is improved.
