Title: Field effect transistor and its manufacture
Inventor: NODA MINORU
IPC: H01L29/80
Filed: 1986-02-04
Abstract: PURPOSE:To realize a stable separation between a gate electrode and an N<+> layer, by forming an insulating film on the whole surface of a substrate after a P-type ion implantation region is formed on a semi-insulative semiconductor substrate on both sides of a gate electrode, implanting N<+> ions from above of the insulating film into the substrate, and performing a thermal treatment. CONSTITUTION:Applying a gate electrode 4 formed on a semi-insulative semiconductor substrate as a mask, P-type impurity is implanted and a P-type layer 8 is formed in the vicinity of an gate end. An insulative thin film 7 is formed on the surface of the substrate 1, and N<+> implantation is performed after a photo resist 2a is formed. Then an N<+> region 5 is formed by a thermal treatment. The insulative thin film 7 is eliminated and an ohmic electrode 6 is finally formed on the N<+> implanted region 5. Thus a P-type layer 8 is formed between the gate electrode 6 and the N<+> layer 5, so that the carrier (electron) of the N<+> layer 5 is recombined in the P-type layer 8, even if the diffusion of the N<+> layer 5 towards the gate end occurs. Consequently the diffusion reaching the gate end scarcely occurs.

Title: Stepping type input device
Inventor: NITSUTA KANEO
IPC: B41J5/10
Filed: 1982-02-15
Abstract: PURPOSE:To improve the efficiency of input operation for a stepping type input device developed for a person having a trouble in the hand, by varying the moving speed of a cursor with a foot operation of keys. CONSTITUTION:An operator shifts a cursor too the line to which a desired character code belongs by means of an intermediate pedal C. Then a right pedal R is trod strong to shift the cursor to the right at a high speed, and the treading pressure is weakened when the cursor gets near the desired character code to slow down the shift of the cursor. When the cursor reaches a proper position, the foot is detached from the pedal to stop the movement of the cursor. Then the pedal R is trod light again to the shift characters one by one, and the cursor is set under a desired character. Under such conditions, an input key 5 is trod by the left foot to feed the data on the desired character code. If the cursor passes beyond the desired place, a left pedal L is trod to set back the cursor to the left. Thus the cursor is set accurately under the desired character.

Abstract: PURPOSE:To minimize trouble to a telephone set user by finding out an improper connection of a telephone set early. CONSTITUTION:When the connection state of a telephone set connection terminal 4 is checked, a control section 15 at first controls a voltage control section 12 to change a voltage applied to the telephone set connection terminal 4. Whether or not the telephone set connection terminal 4 is normally connected is discriminated by receiving a signal from a current detection section 11. When the wiring of the telephone set connection terminal 4 is disconnected, since nothing is connected across the telephone set connection terminal 4, an open state is caused. In this case, even when a voltage change is caused across the telephone set connection terminal 4 by using the voltage control section 12, no closed loop is in existence, then no current flows to the telephone set connection terminal 4 and no current is detected by the current detection section 11. Thus, a connection state discrimination section 13 informs a connection fault to a management company of the terminal network controller via a notice section 14.
