Title: Fuel flow controlling device for fuel cell
Inventor: NARITA HIROYUKI
IPC: H01M8/04
Filed: 1983-09-07
Abstract: PURPOSE:To improve the response performance of a device for controlling the flow rate of fuel for a fuel cell by setting a utilization rate of the fuel with a margin, producing a fuel flow rate corresponding to the utilization rate from a finction generator by using an output current as a parameter and controlling a fuel-flow-rate-controlling valve according to the output. CONSTITUTION:The output current of the fuel cell of a fuel-cell power generation system is detected with a detector 22. The required fuel flow rate function for the normal operation condition is produced with a function generator 32 to obtain a command value. The thus obtained command value is added to the signal of a differential block 33 to produce an amended command value 35. The amended command value 35 is then added to a fuel flow rate correction amount 55 obtained from both the temperature detector of an improver catalyst layer and a fuel flow rate 23. After that, the resulting value is fed to the input of a limiter block 60 for giving an upper and a lower limit (UL) and (LL) through a PID computing element 59, thereby controlling a valve 9 for controlling the amount of fuel fed to the fuel cell. As a result, controlling can be performed while always securing the lower limit of the supplied amount of the fuel and the response efficiency of fuel supply can be improved.

Inventor: WATANABE OSAMU
IPC: C08F12/22
Filed: 1991-06-07
Abstract: PURPOSE:To facilitate the formation of a polymer having a narrow molecular weight distribution and an arbitrarily controlled molecular weight and suited as a resist material or the like by anionically polymerizing p-t- butoxycarbonyloxystyrene. CONSTITUTION:p-t-Butoxycarbonyloxystyrene of formula I is produced, for example, by reacting p-acetoxystyrene with an alkali metal alkoxide to form an alkali metal phenolate and converting this compound into a compound having a t-butoxycarbonyloxy group.

Title: Method for recovering platinum and palladium
Inventor: JII BURIN HARISU
IPC: C22B11/00
Filed: 1990-06-21
Abstract: PURPOSE: To recover pure Pt and Pd by extracting the Pt and Pd while bringing a noble metal-containing acidic soln. containing no Au into contact with a specified org. soln., removing impurities and acid, and then stripping them with a buffer soln. and hydrochloric acid.  
     CONSTITUTION: A noble metal and base metal-containing acidic chloride having a pH smaller than about 1.5 or a mixed chloride/sulfate soln. is brought into contact with an org. solvent consisting of 8-hydroxyquinoline, a phase modifier and an arom. diluent to extract simultaneously the Pt and Pd. The extracted impurities and acid is removed by washing the org. solvent. Then the Pt is selectively recovered by stripping them with the buffer soln. actuating at pH2-5 such as sodium acetate at 20-50°C. Then the Pd is recovered by stripping with the hydrochloric acid. The org. soln. is regenerated by washing with water and the soln. is recycled to the first extracting stage.

Title: Silence section detector for magnetic tape reproducer
Inventor: OBATA KIYOSHI
IPC: G11B15/02
Filed: 1978-12-25
Abstract: PURPOSE: To ensure the tape retrieval by giving the control to the pass of the pseudo featuring the duration proportional to the no signal duration longer than the fixed time via the pulse train of the interval corresponding to the tape running speed.  
     CONSTITUTION: Pulse row generation means 7 generates the pulse train formed by the pulses featuring the interval proportional to the tape speed in coupling to the reel or the like. With this pulse's rear edge, mono-multi 8 is triggered. As multi 8 can be triggered again, it generates the high-level output if the pulse interval becomes short for the pulse train when the tape speed increases. Thus FF10 is set via NOR gate 9, and the output generated is made to pass through NAND gate 13 to which the no signal detection pulse of the duration proportional to the no signal duration longer than the fixed time. And the pseudo detection pulse at the decrement time of the tape speed does not pass. As a result, the reverse control is given to the quick winding direction via the necessary no signal detection pulse, and thus the tape is stopped at the fixed leading position with no malfunction.

Filed: 1980-11-20
Abstract: PURPOSE: To improve safety operation performance, by employing such a mechanism as to control supply of working fluid to a heat collector and a heat storage  tank by detecting temperature of piping on the top of a radiator of the titled  device equipped with the heat storage tank which utilizes working fluid phase  variation and gravitational reflux.  
     CONSTITUTION: When a heat collector 1 absorbs solar heat, a working fluid 9A evaporates 9B to fill up pipings 7AW7D, a radiator 2 and a liquid reservoir 6 and causes very little condensation, causing pressure of steam 9B to rise. On  the other hand, when the temperature of piping on the top of the radiator 2, being detected by a detector 11 becomes higher than a prescribed temperature, a  fan 10 is operated and valves 8AW8D are driven in the direction of 'close', at  the same time. Therefore, the radiator 2 is cooled to lower steam pressure, and  at the same time, supplies of the liquid 9A to the heat collector 1 and a heat  storage tank 3 are stopped, so that the rise in pressure becomes controllable. It is possible, by so doing, to improve the safety of the apparatus.
