IPC: C25B11/03
Filed: 1986-03-27
Abstract: PURPOSE:To prevent the damage of an ion exchange membrane during electrolysis at high current density by using a sintered Ti body having a specified porosity as an electrode substrate and by unitedly forming a Ti layer having a lower porosity on the part of the substrate brought into contact with the ion exchange membrane so as to reduce ohmic loss due to defective contact. CONSTITUTION:An electrode substrate 1 is made of a sintered Ti body having 40-80% porosity and a Ti layer 2 having a lower porosity than the substrate 1 is unitedly formed on the part of the substrate 1 brought into contact with an ion exchange membrane 3 by sintering or other method. The thickness of the Ti surface layer is regulated to about 50mum-1mm. The density of contact points between the resulting electrode and the membrane 3 is increased and the moderate supply of an electrolytic soln. to the membrane 3 is ensured. Accordingly, electrolysis at high current density is enabled and the damage of the membrane 3 is reduced because uniform pressure is applied to the membrane 3.

Title: Refresh control circuit
Inventor: YAMAZAKI TETSUO
IPC: G11C11/406
Filed: 1989-03-24
Abstract: PURPOSE:To make the power supply of required ability enough by preventing real refresh operation from being executed when an address is already accessed at a refresh time. CONSTITUTION:When a system is activated, all the bits of an access register 5 are set to 1. When a CPU 1 executes the normal access, an address selector 4 selects an address (a) outputted from the CPU 1 and the bit of the address register 5 is reset to 0. When the refresh is executed, the address selector 4 selects an address (b) outputted from a refresh counter 2 according to a refresh timing signal (g) to be outputted from a refresh controller 3. At such a time, the relevant bit of the register 5 is read as an address control bit (j) and when this output is 0, a timing controller 6 does not execute the access to a DRAM 7 according to an AND circuit 8. Thus, the power supply of the required ability is made enough.

An impurity implanted layer 36 is transformed into an N<+> gallium arsenide active layer 48. The length of the active layer 47 becomes short by the diffusion of impurities. Then, a source electrode 49 and a drain electrode 50 comprising ohmic metal are formed. The size of the N-gallium arsenide on the drain side is longer than that on the source side. Therefore, the withstanding voltage of the drain becomes high. As a result, high efficiency and high output power can be provided.
