Abstract: PURPOSE:To shorten the fire extinguishing time by supplying a current to a blower motor through a normally open contact of a changeover contact of a seismic automatic fire extinguisher and a first temperature switch thereof when the combustion device is overthrown and fire is extinguished. CONSTITUTION:A seismic automatic fire extinguisher 28 operates, a changeover contact 28a is switched from point (i) to (j), supply of current to a solenoid 6 is stopped, and holding of a lever 4 is released and fire is extinguished. Upon this occasion, different from the time of ordinary fire extinguishment, supply of current to an ignition heater 25 is not carried out. Furthermore, a current is supplied to a blower motor 17a through contact (j) of the seismic automatic fire extinguisher 28, a temperature switch 27 and the contact (o) of a relay 39 (as the relay 39 is not supplied with a current, the contacts are switched from (p) to (o). Thus, the blower motor 17 acts to blow out the small flames remaining in the combustion part at the time of the fire extinguishment. When the temperature of the combustion part falls and the temperature switch 27 is opened, supply of current to the blower motor 17a is stopped.

Abstract: PROBLEM TO BE SOLVED: To obtain a member into which large chemical prestress is introduced with little loss in the chemical prestress by kneading a cement compsn. containing a cement and an expanding material to prepare a concrete, forming the obtd. concrete and ageing it in hot water at a specified temp. SOLUTION: A cement compsn. containing a cement preferably of 100 pts.wt. and an expanding material (e.g. hauyne-base, calcium oxide-base material) preferably of 2 to 16 pts.wt. is kneaded to prepare a concrete, which is formed and aged in a hot water at >100 deg.C, preferably at 120 to 200 deg.C, preferably in a vertical pressure chamber. As a result, large expansion strain and compression strength can be obtd. at a lower temp. and in a shorter retention time compared to the process of autoclave ageing. Since hardening of the cement is significantly accelerated, specified compression strength can be obtd. in a short time. Further, specified chemical prestress can be introduced so that the use amt. of the expanding material can be suppressed.

Filed: 1984-07-12
Abstract: PURPOSE:To obtain an inexpensive adsorbent high in adsorptivity of carbon monoxide by forming the adsorbent with the porous granular material of the mixture consisting essentially of copper halide and carbide and interposing copper halide between the granules of carbide. CONSTITUTION:5-40pts.wt. binder is mixed with 100pts.wt. total of copper halide and carbide which consist of 80-98wt% carbide, 20-2wt% copper halide. After molding the mixture to the granular shape, it is calcined in the temp. not more than m.p. of copper halide, normally at 250-400 deg.C preferably at 300-350 deg.C to obtain an adsorbent for carbon monoxide. The calcination is performed in an inert gas such as gaseous nitrogen and gaseous carbon dioxide. Copper halide contained in the obtained adsorbent for carbon monoxide has the structure in which copper halide is interposed between the granules of carbide and has the porous structure as a whole. Therefore, carbon monoxide is selectively adsorbed out of gases.

Title: Motor-driven power steering control device
Inventor: ISHIKAWA HISAZUMI
IPC: B62D5/04
Filed: 1997-05-20
Abstract: PROBLEM TO BE SOLVED: To improve steering feeling by generating friction compensating torque in an electric motor at the time of turning and returning operation of a steering wheel. SOLUTION: When a turn-return discriminating circuit 21 judges the turning operation of a steering wheel, a switch 14 is turned on. Thus, a friction compensating command value of a turning friction compensating command value decision circuit 13 is added to a basic assist command value to be transmitted to a motor current control circuit 11. On the other hand, when the turn-return discriminating circuit 21 judges the returing operation, a switch 18 is turned on. Thus, a friction compensating command value of a returning friction compensating command value decision circuit 17 is added to a basic assist command value to be transmitted to the motor current control circuit 11. Thus, according to the turning and returning operation of the steering wheel, the friction is cancelled or apparently the torque of the same quality as the friction is generated to improve steering wheel.

Title: Two-channel liquid pressure control valve
Inventor: KADOTA SHINKICHI
IPC: B60T8/26
Filed: 1981-09-16
Abstract: PURPOSE:To suppress the discharged liquid from a master cylnder to a small amount  when one channel fails by constituting a coupling structure which, when one of two  channels of tandem type liquid pressure control valves fails, couples so as to move in  the direction to hinder the seal of the poppet valve mechanism of the other channel. CONSTITUTION:The first control valve 12, second control valve 14, and a free piston 16  are provided in a movable piston 32, which is applied with the force of a control spring  34. Poppet valves 20, 38 are provided on valves 12, 14 respectively. Under a normal condition, the movable piston 32 is pulled by the control valve 12 to move to the left,  decompressing the channel A, and the liquid pressure of the channel B is also controlled by the free piston 16. When the channel A fails, the movable piston 32 is moved  to the left by a distance 11 and is stopped by means of the liquid pressure force of  the channel B, and a guide member 48 presses the valve 14 to the stopped piston 16  through a coupling ring 52. Accordingly, the control valve 14 is kept open, thus hindering its seal action and recovering the liquid pressure. When the channel B fails, the movable piston 32 is pressed to the right by a distance 11, and the control valve 12 is kept open. Thereby, when one channel fails, the discharged liquid from a master cylinder is prevented from increasing to a large amount more than the required amount  and the liquid pressure is recovered.

Filed: 1989-06-07
Abstract: PURPOSE:To make it possible to obtain excellent performance in a compression ratio and volume efficiency by setting the thickness of the scroll body of each scroll to dimension different from each other. CONSTITUTION:Scrolls 21 and 22 have base plates and scroll walls 21a and 22a forming enclosed space 23 which moves depending on a relative swing movement. At this point, the thickness of scroll walls 21a and 22a are set to dimensions which are different from each other. That is, the scroll thickness of the fixed scroll is set to a thickness smaller than the scroll thickness of the swing scroll 22. By this, the aperture of a exhaust port 24 can be enlarged without lessening stroke volume by the scroll body whose scroll-like parameter is different. Therefore, excellent performance in a compression ratio and volume efficiency, and so on can be obtained.

Filed: 1981-09-18
Abstract: PURPOSE:To obtain a highly reliable ultrasonic penetrating device by reducing heat stress due to the temperature difference between an inner cylinder and a reflector at the time of scram of a reactor. CONSTITUTION:A reflector 20 has vertical and horizontal keys 23 set up so as to be engaged with respective grooves 21, 22 of an inner cylinder 15 and is fixed on the inner cylinder 15 with a bolt 24.
