IPC: A47L9/28
Filed: 1989-09-20
Abstract: PURPOSE:To miniaturize a floor surface discriminator and improve its shock resistance by using the discriminator comprising a rotatably supported polygonal pillar-shaped detecting roller and a rotation detecting means for detecting rotation of this roller and discriminating a material of a floor surface by the rotational condition of the detecting roller when it is moved into contact with the floor surface. CONSTITUTION:When a bottom part 3' of a supporting main unit 3 is brought into contact with a floor surface F1, and moved in a direction A, the side surface of a detecting roller 1 is fixed and slid in a condition that the side surface is in parallel to the floor surface F1, and therefor the detecting roller 1 is not rotated with no pulse detected, of course, by a pulse detecting circuit 5. On the other hand, in the case of similarly discriminating the floor surface F2 of a carpet, when the supporting main unit 3 is moved in a direction of the arrow mark A, the detecting roller 1 is rotated in a direction of an arrow marks B, and since an actuator 4' of a microswitch 4, coming into contact with this detecting roller 4 is lifted, by the top line of the detecting roller 1, a contact of the microswitch 4 is opened and closed with a pulse detectable as shown by the drawing in a pulse detecting circuit 5. Thus by detecting the pulse in the pulse detecting circuit 5, the floor surface can be discriminated.

Abstract: PURPOSE:To enable a gate resistance to be decreased without increasing the capacity between source and drain, by providing a low resistance layer on a gate electrode such that it is overhung only over the source side. CONSTITUTION:A gate electrode 2 of a high-melting metal such as tungsten silicide or the like is formed on a semi-insulating GaAs substrate 1, so that a rectifying contact structure is provided. Silicon oxide layers 3 are formed on the opposite sides on the gate electrode 2, and on the opposite sides of these silicon oxide layers 3 there are provided a source electrode 45 and a drain electrode 4D both formed of a AuGe/Ni layer, whereby a resistive contact structure is provided. A low resistance layer 5 of a metal such as Au or the like is then formed on the gate electrode 2 so as to be integrated therewith. An overhung section 5a of the low resistance layer 5 is overhung only on the source electrode 45 while it is overhung little on the drain electrode 4D. Since the overhung section 5a of the low resistance layer 5 provided on the gate electrode 2 is present only on the side of the source, the Au layer 5 can be effectively prevented from projecting over the drain side. Accordingly, increase in capacitity between gate and drain CGD can be avoided.

IPC: G11C11/14
Filed: 1983-12-26
Abstract: PURPOSE:To form a pattern with a submicron order gap easily by coating a substrate, to which the mask pattern is shaped, with a film and etching the substrate and the film by accelerated particles. CONSTITUTION:A pattern material layer A is formed on a substrate 1 in thickness tA, and a mask pattern B in thickness tB is shaped on the layer A by a photo-resist material through a photolithography technique. A film C is formed on the exposed surfaces of the pattern material layer A and the mask pattern B in thickess TC so that the undulating shape of the mask pattern B is maintained approximately. Consequently, the mask pattern B is thickened, and gap width G2 is made narrower than initial gap width G1. The film C and the pattern material layer A are etched by using accelerated particles. The gap width of the mask pattern B is further narrowed because one part C' of a material for the film C adheres on the side surface of the pattern B again at that time.
