Title: Controlling method of parallel synchronous operation
Inventor: TAKI KENICHI
IPC: G06F9/52
Filed: 1982-06-30
Abstract: PURPOSE:To secure synchronism, by dividing the frequency of a clock signal through plural microprocessors, comparing one of frequency-divided signal as a reference signal with others, and inhibiting clock input for signals with differences and making corrections. CONSTITUTION:A clock signal CK from an oscillator 3 is inputted to the normal and reverse input terminals of a main processor 1, which outputs a main frequency-divided signal Cm. When frequency-division outputs Cs and Cm of a slave processor 2 are both at a level ''0'', the output Ga of an ENR5 is at a level ''1'' and an FF6 latches it; when the signal CK rises, the FF6 is triggered and an AND gate 7 generates an output. A positive and a negative signal CK are inputted to the slave processor 2, which starts outputting a subordinate frequency- divided signal Cs; and the outputs Cm and Cs are out of phase with each other and the output Ga goes down to the level ''0'' to cut off the signals to the processor 2, so that the Cs is at the level ''0'' continuously. When the CK goes down to ''0'', the ENR5 generates the output again and the gate 7 outputs ''1''. At this time, the Cm and Cs are put in phase at the timing of the CK. Thus, the synchronism is secured.

Abstract: PURPOSE:To perform the test of a logic circuit positively and readily by adding a circuit which can select the input voltage of a differential signal that is imparted to a differential amplifier at a voltage at the time of normal operation or at a voltage at an intermediate level. CONSTITUTION:Input signals to logic circuits 11 and 12 including differential amplifiers are selected as any of differential input signals 7 and 8 at the positive or negative side or an intermediate level voltage 4 through input selecting circuits 2 and 3 at the positive side and the negative side. Input control signals S1 and S2 are inputted into the circuits 2 and 3 in addition to the signals 7 and 8 and the voltage 4. The S1 controls the positive side, and the S2 controls the negative side. When, e.g. the voltage 4 is selected at one negative input terminal of the signals 7 and 8, one degenerate fault of S-P of the circuit 11 is detected. When I-P is made to be 0 and I-N is made to be 1 as the input signal for e.g. the circuit 11, the fault can be detected. Therefore, when the negative voltage 4 is selected at the negative side, the positive side can be diagnosed. When the voltage 4 is selected at the positive side, the negative side can be diagnosed.

Title: Ion-exchange granulation of modified calcite
Inventor: KATO HIDEO
IPC: C01B39/02
Filed: 1993-05-18
Abstract: PURPOSE:To provide a new process for granulating coal ash into artificial zeolite for profitable utilization of a large amount of coal ash from a power plant or the like. CONSTITUTION:Coal ash is hydrothermally treated with an alkali aqueous solution to effect modification, then purified by liquid separation, water rinsing, and dehydration to prepare modified coal ash. The modified coal ash and more than 15wt.% of a cement binder based on the total materials, as major starting materials, are mixed into paste by stirring the mixture at the initial rotation speed to separate water thixotropically, then kneaded and dried at the rotation lower than the initial. When the water content attains the optimal level for granulation, granulation and drying are performed at a higher rotation than the initial. The process enables the simple and efficient production of artificial zeolite of high mechanical strength and high ion-exchange percentage without disintegration.

IPC: H01L21/3205
Filed: 1988-05-11
Abstract: PURPOSE:To restrain increase of leakage currents through a diffusion layer by selectively removing a silicon film using wet etching, after implanting ions of impurity into the silicon film, so as to selectively form the silicon film at the side face or the bottom of a contact hole, and then forming a tungsten film selectively. CONSTITUTION:After a contact hole 102 is opened in a between-layer insulation film 101 or a substrate 104, a polycrystal silicon film 103 is formed on the whole face. Next, arsenic ions are vertically implanted into a substrate 104. By this processing, arsenic is doped into a polycrystal silicon film 103 coated on a part other than the side face of the contact hole 102. Next, by wet etching, leaving only the polycrystal silicon film 103 coated on the side face of the contact hole 102, polycrystal silicon film at other parts is removed. Next, a tungsten film 105 is made to grow selectively inside the contact hole 102. Hereby, since contact hole side face is covered with a silicon film, deterioration of leakage currents can be completely checked.
