Title: Post-treatment of distilled water
Inventor: SAWADA IWAO
IPC: C02F1/20
Filed: 1984-02-02
Abstract: PURPOSE:To contrive to miniaturize equipment and to reduce equipment cost, in a method for treating distilled water obtained by a brine desalting apparatus with a Ca- salt and CO2 obtained by decarbonation treatment of seawater, by using CO2 obtained by adding an acid to seawater in a divided form. CONSTITUTION:Seawater is mixed with a controlled amount of an acid supplied from an acid tank 3 through a regulation valve 4 and, thereafter, injected into a decarbonation apparatus 5 where contacted with the open air to be decarbonated while CO2 is exhausted along with air. The residual seawater accumulated to the bottom part of the apparatus 5 is sent to a degassing apparatus 12 but the pH thereof is detected in a pipe 11 and the opening degree of the valve 4, that is, the acid injection amount is regulated on the basis of the detection value to allow the residual seawater to retain an unreacted bicarbonate ion. This seawater receives the injection of the acid through a regulation valve 14 and, thereafter, injected into the apparatus 12 and degassed under vacuum while the pH thereof is detected to regulate the valve 14. pH adjusted seawater is treated in an evaporation type brine desalting apparatus 9 to be converted to distilled water which, in turn, enters a limestone bed 21. Gas such as O2 or N2 containing CO2 extracted by a steam ejector 22 from the apparatus 12 is separated from condensed water therein and, thereafter, introduced into distilled water in a pipe 20 under pressure through a compressor 24 and absorbed thereby.

IPC: F24C3/06
Filed: 1979-02-21
Abstract: PURPOSE: To save a fuel by a method wherein a gas table having a timer is provided with means for automatically adjusting and terminating a supply of gas in  response to a cooking condition.  
     CONSTITUTION: When a pan 1 is boiled to increase a vapour pressure, a packing 5 is bulged out by the pressure to lift up the cap 4. This movement is transmitted to the shaft 8 through shaft 7, the shaft 14 is depressed by the shaft 8, a movement of the shaft 14 is transmitted to the wheel 18, and then transmitted to the operating rod 16 from the wheel 19. The operating rod 16 depresses an opening and closing valve 15 and thus the gas flame is changed from a strong one to a middle one. Further, when the pressure in the pan is increased, the operation rod 16 is moved away from the groove of the wheel 21, a rotation of the spring is applied to the gear 20 through a changing gear 43 to rotate a shaft of the knob 24 and at the same time a display plate for informing the boiled condition is rotated by the gear 57. When the shaft of the knob 24 is started to rotate, the wheel 22 is also started to rotate, and at the same time the shaft 23 is moved, removed from a scale plate, pushed up by a spring for the wheel 22. At this time, the operation rod 16 is fully lifted up, the valve is completely closed to distinguish the flame.

Title: Method for cutting edged copper coated laminated plate
Inventor: SEKINE HIDEO
IPC: B23Q17/20
Filed: 1988-01-30
Abstract: PURPOSE:To cut off an edge portion by one process and cut a laminated plate to size by cutting the edged copper-coated laminated plate to size after moving the laminated plate by a set quantity with the position of a base-material end obtained by detecting the change in the thickness of the end portion thereof as the reference point. CONSTITUTION:An edged copper-coated laminated plate 1 is fed by advancing a brush 5 and, as the laminated plate 1 is held between bearings 3 and 4, the brush 5 is retracted while also retracting the laminated plate 1. At this time, the upper and lower bearings can be rotated even though being pushed by an air cylinder, without causing damage to the laminated plate. Then, as the laminated plate 1 continues to be retracted and, on reaching the end portion of the portion of only upper and lower foils out of a base material, the bearing 3 is lowered by the amount of the thickness of the base material. At this time, as the distance between a metal block 6 and an eddy current type displacement sensor 7 is changed, the value of a current is changed and because of a signal exceeding a set value, the retraction of the brush 5 is stopped making this position a reference point. At this time, the other end portion of the laminated plate 1 is fixed by means of a chuck 8 and by feeding same by a defined distance, shearing is performed by cutting edges 10 while repeating this action successively.

Title: Vehicular suspension control device
Inventor: AOTANI TOMOAKI
IPC: B60G17/015
Filed: 1991-02-14
Abstract: PURPOSE:To heighten the safety of travel with a tire with reduced air pressure by discriminating whether the air pressure of the tire is the specified value or less from the vibration frequency of the tire detected by an vibration frequency detecting means, and performing the driving control of an oil damper onto the soft side in response to discrimination output from an air pressure discriminating means. CONSTITUTION:The characteristic frequency of a tire 1 with reduced air pressure is detected by an acceleration sensor 7, and after filtering the output of the acceleration sensor 7 by a band-pass filter 8, the decrease of air pressure in the tire 1 is discriminated by an air pressure discriminating circuit 9a. An oil damper 6 is then controlled onto the soft side by the output of the discriminating circuit 9a through an oil damper driving part 10. A coil spring 5 is thereby made soft to absorb a shock, applied to the tire 1, by the coil spring 5, so that the tire 1 is prevented from becoming flat, for instance, to heighten the safety of travel.

The possibility that the optical fiber is thermally stressed is eliminated in this way.
