Title: Production of mixed gas containing hydrogen in definite concentration
Inventor: FUJITA YUUKOU
IPC: C25B9/19
Filed: 1983-08-05
Abstract: PURPOSE:To produce a hydrogen-containing mixed gas having a hydrogen concentration of high industrial value, by removing hydrogen at the anode of an electrochemical hydrogen-separation apparatus using an ion exchange resin, and utilizing the residual gas left after the separation of hydrogen. CONSTITUTION:An ion exchange resin membrane 1 prepared by introducing sulfonic acid group to a perfluorocarbon resin base is integrated at one surface with the cathode 2 and at the other surface with the anode 3, and is furnished with the charge collectors 4, 5 for the anode and cathode, the terminal plates 6, 7 for the anode and cathode, and the cell frame 8. The primary mixed gas having relatively high H2 concentration and humidified to the saturated state is introduced into the cell through the gas inlet 9, and a DC current is passed through the terminal plates 6, 7. H is ionized at the electrode 3, and H2 is generated at the electrode 2. The generated H2 is discharged through the outlet 10. The secondary mixed gas having relatively low hydrogen concentration and left after the partial consumption of H2 at the electrode 3 is discharged through the outlet 11. Since the H2 concentration of the objective gas is a function of the H2 concentration of the primary mixed gas, the rate of feeding and the operating electrical current, the variables are controlled to attain a constant H2 concentration.

Title: Caller number display system
Inventor: TAMURA TAKAKAZU
IPC: H04W4/02
Filed: 1989-06-05
Abstract: PURPOSE:To recognize a caller giving a message to its own telephone set among lots of unspecified callers by storing a caller number making a call to a mobile terminal equipment by a radio exchange station. CONSTITUTION:When power is interrupted, a mobile terminal equipment (CLD) 31 with display section in a cell 3 gives no response to a call signal and a central controller(CC) 23 discriminates it that a called party CLD 31 is subjected to power interruption or resident at the outside of the service area. The CC 23 in this case stores the result of a caller number request, that is, the caller number inputted from the caller telephone set (CLG) 10 to a subscriber data relevant area of the called party CLD 31 in an MM 24. Thus, the caller number as to the call arrived during power interruption or residence at the outside of the service area is displayed onto its own telephone set by allowing the CLD 31 to have only to apply its power supply or to dial a predetermined service code, then the caller giving a message to the called party is recognized.
