Title: Digital signal relay and exchange system
Inventor: YAMAGUCHI KENICHI
IPC: H04Q11/04
Filed: 1986-07-18
Abstract: PURPOSE:To prevent the deterioration in quality of a voice signal by compressing processing by allowing an input-side digital multiplexer to give a compression signal of a relay call to an exchange without decoding and allowing an output-side multiplexer to send a signal given from an exchange as a signal already compressed while multiplexing it as it is. CONSTITUTION:Compression switching control sections 32, 35 send a switching signal to corresponding decoding processing section 33 and compression processing section 34 to a notified line number to control them to bypass the decoding and compression processing. The decoding processing section 33 and the compression processing 34 have similar decoding and compression functions to that of conventional circuits, but do not execute decoding/compression reserving the switching signal, transmit/receive the compression signal to/from an exchange 20 in a way that the compression signal received from a relay line is sent to the outgoing relay line as it is with multiplexing by the bypassing of the sections. Since no decoding and re-compression is applied with respect to the relay call, the deterioration the quality of the voice signal based on the compression in the, multi-stage relaying is prevented.

The light valve 15 possesses a spherical reflection surface whose recessed surface is faced to the side of the projection optical system. Then, after the signal light emitted from the light valve 15 is moreover condensed through the front group 14 of the projection optical system, it is made incident on the polarizing beam splitter 13 again.  The signal light transmitted the polarizing beam splitter 13 is projected on a screen 17 arranged on the optical axis AX of the projection optical system through the rear group 16 of the projection optical system.

Title: Vertical-type electric furnace
Inventor: SENDA NOBUHIRO
IPC: H01L21/31
Filed: 1991-06-17
Abstract: PURPOSE:To efficiently cool the intermediate part inside a furnace by a method wherein the cooling air is introduced, from the top wall and the central part of a furnace wall, into the space between a soaking tube surrounding a vertical- type reaction tube and a coil heater around the furnace wall. CONSTITUTION:The cooling air is supplied to a space 6 from ports 8 and ports 15. Since the central part inside a reaction tube 2 becomes a highest temperature, the cooling-air introduction ports 15 are added to the part. The cooling air which has enterd from the ports 8 absorbs heat from the upper part which is going to maintain a high temperature, and lowers the temperature inside the upper-part reaction tube 2. The cooling air which has absorbed the heat from the upper part is mixed with the cooling air which has entered from the ports 15; it lowers the temperature of the reaction tube; it flows to the lower part while it is cooling the central part of the reaction tube 2; and it flows out to the outside from exits 12 via a manifold 13 and discharge ports 14. Thereby, the introduction ports of the cooling air form the intermediate are effective in uniformly lowering the temperature, and the high-temperature air can be cooled effectively when it is pushed out from the upper part to the lower part.

Abstract: PURPOSE:To reduce the number of external parts at the formation of an integrated circuit and to attain an essential operation independently of the resistance value of a variable resistor by newly adding a NAND circuit and an AND circuit to a conventional circuit. CONSTITUTION:The NAND circuit 2 and the AND circuit 10 are added. When a trigger pulse is inputted to an input terminal 1, a waveform differentiated by the leading edge of the trigger pulse is generated from the output 18 of a NAND circuit 4. When the resistance value of the variable resistor 12 is turned to '0', the output 21 of a comparator 14 is always kept at 'H'. The output 21 becomes an output 19 always kept at 'H' through an inverter circuit 16 and a NAND circuit 6 and a D-type FF 7 is held at the reset status, so that the output 20 of an inverter circuit 8 is always kept at 'H'. The NAND circuit 2 finds out NAND logic between the trigger pulse and the output 21 and generates an output 23 kept at 'H'. The AND circuit 10 finds out AND between the output 23 and the output of the circuit 8 and outputs the final output to a terminal 17. Thus, a conventional externally fixed resistor can be removed.

Abstract: PURPOSE:To easily and accurately take a measurement and to form an image by providing an opening part in a member which is opaque to light with specific wavelength and transparent to visible light, and limiting the light with the specific wavelength by the opening part. CONSTITUTION:This is an element having a stop function to the light with the specific wavelength, and the opening part is formed in the transparent member which is opaque to the light with the specific wavelength and transparent to the visible light to control the light with the specific wavelength.

A mark 12 is added to the range where the infrared light is transmitted so as to which position the infrared light impinges on. When the visible light is projected, light is transmitted through the entire surface (material 10 and part 11) of the opening part, so positioning is facilitated and when the infrared light is projected at the time of measuring operation, the light is transmitted through only the part (part 11) of the window, so this element operates effectively as a stop.

Abstract: PURPOSE:To grow a thick-film having small lattice mismatching and no misfit dislocation by hetero-joining a second semiconductor layer, in which C is added to an Si-Ge alloy, with a first semiconductor layer mainly comprising Si and having a large lattice constant. CONSTITUTION:A chemically cleaned Si (100) substrate is introduced to a molecular beam epitaxy device, and an Si surface is cleaned through heat treatment under an ultra-high vacuum. The temperature of the Si substrate, the surface of which is cleaned, is set at 600 deg.C, and the growth of Si-Ge-C is started after the temperature is kept constant. The beam intensity of Si, Ge and C is set at approximately 80 : 18 : 2 at that time, and an Si-Ge-C film is grown. When the thickness of the Si-Ge-C film is brought to approximately 1mum, the growth of the film is stopped. Accordingly, the lattice constant of Si-Ge-C manufactured approximately coincides with that of the Si substrate, thus acquiring the film having extremely low dislocation density and excellent crystallizability.
