Title: Narrow channel FET mfr. - includes etching field oxide beneath photoresist mask to form wide aperture through which substrate is depletion implanted
Inventor: JONES ROBERT KEITH
IPC: H01L29/10
Filed: 1979-03-24
Abstract: The FET is fabricated by forming on the field oxide a photoresist mask having a relatively narrow aperture. The field oxide is over-etched beneath the photoresist mask aperture to form a relatively wide aperture in the field oxide, leaving a photoresist overhang. The substrate is implanted through the relatively narrow photoresist mask aperture to provide an enhancement section of the channel region and the photoresist mask is removed. The substrate is depletion implanted through the relatively wide field oxide aperture. The gate structure is formed over the combined enhancement and depletion channels and a source and a drain span the ends of the channels. This effectively provides an enhancement FET which is in parallel with a depletion FET.

Title: Sand pressure moulding for brick mfr. - compensates for moisture in sand by controlling volume of compressed sand
Inventor: VOGT WILLY
IPC: B30B11/00
Filed: 1980-06-13
Abstract: The system measures the moisture content of sand before its introduction into the mould. The volume of sand introduced into the mould is adjusted to compensate for the moisture present in the sand. The volume is changed by means of a vertical piston coupled to a controller to which the moisture meter is connected. The moisture meter may be in the slide that conveys the sand to the mould or it may be in the hopper containing the sand. The advantage of the system lies in the production of bricks of uniform size despite variations in moisture content. Other production variables do not require adjusting.

Patent DE-3034168-A1 (DE)
Inventor: STRAESSLE EUGEN
IPC: F24F1/0358
Filed: 1980-09-11
Abstract: Also arranged in the housing (11) of this apparatus, in addition to a blower (20) for conveying air and blowing it out, is a dehumidifier unit (30) which has a coolant circuit (31) with an evaporator (32), with a condenser (33) and with a compressor constructional unit (34). Some of the air sucked in by means of the blower (20) is guided along the evaporator (32), the condenser (33) and the compressor constructional unit (34). The evaporator (32) serves for cooling the air flowing past to a temperature below the dew point of the moisture contained in the air, so that water is precipitated from the air. The precipitated water is intercepted in a collecting container (36). The dehumidified air cools the condenser (33) and the compressor constructional unit (34), the air experiencing heating to a temperature a little above the original temperature. Other air sucked in by means of the blower (20) is not dehumidified and is admixed with the dehumidified air when it is blown out. This apparatus allows an energy-saving drying of laundry in a room of a building, from which no hot air must be released into the open. <IMAGE>
