Patent JP-H02250333-A (JP)
Title: Manufacture of thin-film field-effect transistor array
Inventor: NISHIDA SHINICHI
IPC: H01L29/78
Filed: 1989-03-23
Abstract: PURPOSE:To give a different characteristic to only elements in one part on a transistor array by a method wherein atoms whose own polarizability is high or atoms which can change an electronic state of a film largely are ion- implanted into a region which is sufficiently distant from an interface between a silicon thin-film and a gate insulating film. CONSTITUTION:A source electrode and a drain electrode 6, 7 are formed; silicon thin films 4, 5 and a gate insulating film 3 are formed on them; in a state that the gate insulating film 3 of a transistor 8 whose threshold value is to be changed protrudes on the surface, ions of a heavy metal such as Ta or the like are implanted in such a way that impurities are distributed in a region which is sufficiently distant from an interface between the gate insulating film 3 and a channel layer. Accordingly, a permittivity of the gate insulating film 3 of a selected thin-film transistor becomes large; as a result, a gate capacity becomes large; the insulating film behaves in such a way that a mobility of the thin-film transistor has become equivalently large. Thereby, it is possible to form a flexible thin-film transistor array without changing a channel width.

Title: Knocking control device for engine equipped with supercharger
Inventor: KAGEYAMA HIDETOSHI
IPC: F02B37/12
Filed: 1982-05-04
Abstract: PURPOSE:To prevent knocking, by providing a valve in a passage running from a compressor to an actuator of waste gate valve and by opening and closing the valve. CONSTITUTION:While an engine 1 is not knocking, a solenoid valve 19 provided in a branch passage 11b remains closed and an actuator 9 remains inoperative, thereby keeping a waste gas valve 8 closed. The actuator 9 receives a supercharging pressure of a compressor 3, and therefore a waste gate valve 7 is caused to open and close by the supercharging pressure. Upon an engine beginning to knock, such a vibration is detected by a knock sensor 15, whereas a knocking control circuit 17 determines the knocking for openning the solenoid valve 19. The supercharging pressure begins to affect on the actuator 10, and an exhaust gas partially bypasses from the waste gate valve 8 into a passage 6.
