Title: Manufacture of semiconductor device
Inventor: OSANAI JUN
IPC: H01L21/28
Filed: 1986-07-01
Abstract: PURPOSE:To improve the electrical characteristics of a contact section, and to conduct the activation of an impurity besides the selective silicification of a high melting-point metal by forming a high melting-point metallic silicide between an impurity region in an Si substrate and a wiring metal. CONSTITUTION:A high melting-point metallic silicide 6 is inserted between a wiring metal 7 and an impurity region 2 in an Si substrate 1. Since the silicide 6 is inserted even when pure Al is used as the wiring metal 7, pure Al does not react directly with the Si substrate 1, and there is no possibility of alloy spike. Even when an Al-Si alloy is employed as the wiring metal 7, the contact exposed section of the Si substrate 1 is covered completely with the silicide 6, and the preferential position of precipitation is removed, thus dispersing the precipitation of Si. Precipitation is further dispersed by adopting high- temperature short-time treatment, and the silicide 6 can form an ohmic contact with Si and Al as physical properties.

IPC: G10L19/06
Filed: 1989-06-19
Abstract: PURPOSE: To efficiently code a tone by selecting a subband signal suitably matching a source signal from subband signals generated by dividing the frequency bandwidth of the base band signal sampled at a 1st range into two subband signals and sampling them at a rate lower than the 1st rate. CONSTITUTION: A signal X(n) supplied by an adder is sent to a low-pass filter LPF 90 and a high-pass filter HPF 91 to obtain filtered signals y1(n) and y2(n). The signals y1(n) and y2(n) are divided by down-sampling device 92 and 93 into two signals x1(n) and x2(n), and x3(n) and x4(n) which are sampled at a 1/2 rate. Those signals are sampled up by devices 94 and 95 and converted to the original sampling rate, and errors d1(n) and d2(n), and d3(n) and d4(n) are derived to derive energy data Ej (j=1, 2, 3, and 4) through an inverse short- section filter 1/A(z). Eventually, an RPE sequence xj(n) which is selected by a device 100 and is quantized is the minimum Ej.

Abstract: PURPOSE: To make it possible to supply a proper amt. of toothpaste from a container body to a brush part by providing a part of this container body with restitutive elastic force to pressurize the inside of the container body and absorbing air into the container body at resetting after pressing. CONSTITUTION: The side wall of the container body 1 is bored with a through-hole 7 and the outer flank and the pressing body 8 consisting of a material, such as, for example, ester elastomer or silicone rubber, having the restitutive elastic force, is joined in an air tight state to the outside flank of the body so as to close this through- hole. A user presses the finger cushion to the apex of the pressing body 8 and puts a space part 2 into a pressurized state by operating the pressing body so as to press the body toward the side wall of the container body 1. The toothpaste housed in this space part 2 passes a check valve 11 and arrives at a brush part 5 through a teeming path 6. When the user releases the finger from the pressing body 8, the pressing body 8 is forced by the restitutive elastic force to be rapidly returned to the original hemispherical shape.  At this time, the check valve 11 operates and, therefore, a negative pressure is temporarily generated in the space part 2 and a cavity part 9 communicating with this part, and the slit of a section part 10 closed thus far in the pressurized state is opened and the air is supplied to the space part 2, by which the atm. pressure is rapidly restored.
