IPC: C21D9/60
Filed: 1978-07-31
Abstract: PURPOSE:To raise the efficiency of heating of the side edges of a slab in hot rolling, by correcting the vertical warp of the front end of the slab to reduce the air gap of an edge heater. CONSTITUTION:When the slab 1 whose front end is warped upward is conveyed to the edge heater 4, profiling rolls 6 are moved forward in accordance to a signal from a material detector until the rolls 6 come into contact with the end of the slab 1.

Title: Personal computer having reset function
Inventor: YOSHIDA MASAO
IPC: G06F1/24
Filed: 1983-05-27
Abstract: PURPOSE:To prevent the erasion of information in a simple way by connecting an input signal line led from a reset key of a personal computer containing a dynamic RAM memory to an interruption input terminal and continuing the refresh function of the dynamic RAM. CONSTITUTION:Only the reset signal obtained in a power-on mode is supplied to the RESET input of a microprocessor Z80, and the reset signal obtained by a reset key is supplied to the non-maskable interruption input signal NMI. Thus the RESET works in a power-on reset mode, and the refresh is not performed for the dynamic RAM. When the reset key is switched on, this information is fed to the NMI as a non-maskable interruption. Then a program is restarted from a specific address. Here a program which performs the substantial reset processing is called out. Thus the refresh function of the dynamic RAM works continuously in a normal way, and the inform of the dynamic RAM is never erased.

Filed: 1984-05-08
Abstract: PURPOSE:To lower the resistance of an element, and to inject carriers efficiently to an active layer by forming an n type electron injecting region to one side end section of the active layer and a p type hole injecting region to the other side end section of the active layer. CONSTITUTION:Currents flow to an active layer 4 through a p<+> type cap layer 6 and a p type hole injecting region 21 from a p type electrode 9, and flow to an n type electrode 1 from an n<+> type cap layer 22 through an n type electron injecting region 20. Since currents cross the active layer 4, carriers are all injected to potential well layers 10, 11, 12, 13 regardless of the magnitude of the potential of carrier layers 14, 15, 16 in the active layer 4. When the width of the active layer 4 is made shorter than the diffusion length of electrons, electrons and holes emit light and are recombined in the potential well layers. Differences among the potential of the barrier layers and the potential well layers are formed sufficiently, carriers are confined effectively and used as a two element group, and carriers are injected efficiently, thus preventing the elevation of element resistance.
