Patent EP-0003231-A1 (EP)
Inventor: PFLEIDERER HANS-JORG
IPC: H01L29/78
Filed: 1978-12-18
Abstract: Die Erfindung betrifft einen MIS-Feldeffekt-Transistor, der aus einem mit einer Isolierschicht (2) bedeckten Halbleiterkörper (1) mit einem jeweils von einer Elektrode (16, 17) kontaktierten Source-Gebiet (3) und Drain-Gebiet (4) vom ersten Leitungstyp und einer dazwischen angeordneten Gate-Elektrodenschicht (18) besteht. Diese Gebiete sind von einem weniger stark dotierten Gebiet (10, 11) vom ersten Leitungstyp umschlossen. Auf der Source-Seite schließt sich daran ein weiteres Gebiet (14) vom zweiten Leitungstyp an, das unterhalb der Gate-Elektrodenschicht (18) an die Halbleiteroberfläche angrenzt. Die Dotierung wird durch differentielle Implantation mit unterschiedlichen Eindringtiefen erzeugt. Als Implantationsmaske wird dabei eine Maske mit abgeschrägten Kanten an den Fenstern über Drain-Gebiet (4) und Source-Gebiet (3) verwendet, die vorteilhaft von der Isolierschicht (2, 7) und/oder der Gate-Elektrodenschicht (18) gebildet wird. Dieser Feldeffekt-Transistor ist wegen seiner hohen Durchbruchsspannung und der von der kurzen Kanallänge (L) hervorgerufenen hohen Schaltgeschwindigkeit für integrierte Halbleiterschaltungen besonders geeignet.

Abstract: Two-stage gas valve having a valve housing (1) and a drive element (12) for the successive operation of two final control elements (5, 9). A first final control element (5) is closed when the load is low and does not open until full load is applied. A second final control element (9) is connected in series with an aperture (6) in the gas flow and opens when the load is low. The low load flow rate is governed only by the aperture (6). The latter can be set from outside the valve housing (1) by a movement direction of the drive element (12) which does not influence the position of the final control elements (5, 9). Valve plates (5, 9), operated by the raising of a ram (12) are used as the final control elements, of which valve plates (5, 9) one opens under full load and carries with it the aperture (6), a valve seat (8) and the valve plate (9) for low load. Two perforated discs (13, 14) located on top of one another and which can be offset with respect to one another by rotation of the ram (12) are used as the aperture (6). <IMAGE>

Abstract: A coin testing apparatus comprises transmitting and receiving coils (14) and (15) on opposite sides of a coin passageway (11). The transmitting coil is connected to high and low frequency oscillators (16) and (17). The output of the receiving coil is separated into the high and low frequency components by a high pass filter (21) and a band pass filter (22). In the high frequency channel the signal is amplitude controlled by a voltage controlled amplifier (23) rectified by a rectifier (24) and smoothed by a long time-constant circuit (26). The initial rise in level caused by a coin entering between the coils (14) and (15) is detected by an instantaneous level change comparator (32) which responds to the rate of change of signal level at the output of the long time-constant circuit (26) becoming equal to preset threshold and causes a normally closed switch (27) to be opened. When the switch (27) is closed a comparator (31) compares the signal with a reference value from a source (30) and adjusts the gain of the amplifier (23) until the signal corresponds to the reference value. Upon the arrival of the coin the switch (27) is opened and a long time-constant circuit (28) causes the gain of the amplifier (23) to be maintained at the level before the arrival of the coin. A window comparator (33) compares the difference in voltage with voltage ranges for acceptable coins. A similar arrangement is provided in the low frequency channel but with two differences. The switch (27) in the low frequency channel is operated by the same instantaneous level comparator as is used for the high frequency channel and instead of a rectifier (24) a novel sample and hold technique is used for providing a d.c. signal from the output of the amplifier (23).
