Filed: 1990-02-07
Abstract: PURPOSE:To attain the substitution with a registered phrase with no re-input of abbreviations even at the editing processing of the document data by providing a registered phrase memory, an abbreviation substitution control means, etc. CONSTITUTION:When the document data are inputted via a keyboard 3 and produced and edited, the control is started with operation of an abbreviation substitution key carried out when the word data equivalent to a single print line including a cursor are stored in a line buffer 32. Then the words pointed by the cursor are read out of a text memory 31 by a text pointer 35 based on the data on a cursor pointer 33 and the cursor line data. Then a registered phrase memory 36 is retrieved for the abbreviation equal to a pointed word. When this abbreviation is detected, the pointed word is erased from the memory 31. Then the data on the registered phrase corresponding to the same abbreviation is read out of the memory 36 and put into the memory 31. When the same abbreviation is not detected, a buzzer 12 works. Thus the substitution is possible with a registered phrase with no re-input of abbreviations even at the editing processing of the document data.

Title: Hydrogen pressure control valve

IPC: F17C11/00
Filed: 1992-02-14
Abstract: PURPOSE:To control the pressure of hydrogen expelled from metal hydride(MH) in a metal hydride tank in a predetermined pressure range with the use of only a mechanical arrangement. CONSTITUTION:When the pressure of hydrogen led into a diaphragm chamber 301 from a metal hydride tank 2 is lower than a predetermined value, a valve stem 302 is lifted up by means of a spring 303 so as to open a valve 305. Coolant for a hydrogen engine 1 is led into a heat-exchanger 202, after flowing from a port 306 to a port 307. When heat is fed into the metal hydride 201 from the heat-exchanger 202 so as to promote expelling hydrogen, resulting in an increase in the pressure of the inside of the metal hydride tank 2. When the pressure of the inside of the metal hydride tank becomes higher than a predetermined value, the valve stem 302 is depressed so as to open the valve 304. Accordingly, the engine coolant bypasses the heat-exchanger 202 so that no heat is fed to the metal hydride 201, and a result, the expelling of hydrogen is stopped so that the pressure of hydrogen in the metal hydride tank 2 is lowered.
