Title: Data transmission system and apparatus providing multilevel differential signal transmission
Inventor: PEETERU HERARUDEYUSU MARIA BAR
IPC: H04L25/49
Filed: 1991-05-21
Abstract: PURPOSE: To provide data transmission system and device for providing multi- level differential signal transmission. CONSTITUTION: In this data transmission system for providing the differential transmission of a binary interface formed by plural binary input signals, the binary interface is coded by a coder to a corresponding multi-level differential interface formed by plural multi-level signals, and such matching corresponds to a code conversion chart selected in advance and the respective multi-level signals are transmitted over respective transmission channels. When reception is performed in a decoder, a difference between the respective pairs of the multi-level signals is detected and binary values are specified to the respective output signals of the decoder by the inverse of the code conversion chart used for coding corresponding to such a code.  The differential transmission achieves resistance from common mode noise and multi-level coding enables the differential transmission of channels fewer than the channels required for binary differential transmission.

IPC: F02D9/02
Filed: 1978-09-22
Abstract: PURPOSE: To provide fine adjustment of suction air in an internal combustion engine, by making a throttle valve composed of a main valve for full throttling of the air passage and a sub-throttle valve for partial throttling.  
     CONSTITUTION: A main throttle valve 26 can fully block a throttle bore 23, and a sub-throttle valve 27 downstream of the main valve can block half the bore 23. A valve opening mechanism 35 is activated by a negative pressure, generated as the main valve 26 is opened, in the narrowest part 32a of a Venturi 32 to open the sub-throttle valve 27. Both valves 26, 27 may be interlocked with each other. The fine adjustment of air flow by a single valve is difficult, if the valve diameter i large, but the two-valve system can ficilitate the operation because the change in cross sectional area of air passage in comparison with the change in valve angle is reduced.

Title: Detection of voltage
Inventor: ASO MAKOTO
IPC: G01R19/165
Filed: 1987-05-13
Abstract: PURPOSE:To obtain a voltage detection characteristic more than equal to that of a Schmitt trigger circuit, by a method wherein one of an input and a common is used as reference to determine a lease potential of an FET through a constant voltage element from the reference and changes in the voltage between the input and the common are applied to a gate of the FET. CONSTITUTION:When a potential on the source side of an N-channel junction type FET2 of a transient response circuit made by applying a voltage detection method becomes higher than that on the drain side of a P-channel junction type FET, internal impedances of the FETs 1 and 2 rise. With this operation, an output with a better rising or falling is obtained from the drain or the source of the FET1 or the drain of the FET2. An output also can be obtained from the drain side of the FET2. Resistances 6 and 7 of a light emitting diode 5 are selected to light the diode 5 with the FET1 ON while extinguishing it with the FET1 OFF. Thus, this provides a voltage detection characteristic equal to or more than that of a Schmitt circuit.

Title: Supporting method of heat transmission pipe at heat exchanger
Inventor: TAKEDA SHIYOUICHI
IPC: F28F9/00
Filed: 1978-09-26
Abstract: PURPOSE: To decrease thermal stress without reducing largely the natural frequency thru a mechanism wherein both the supprting method for the purpose of fixing the heat transmission pipes and another suporting method for increasing the natural frequency of the heat transmission pipes but does not restrain the thermal expansion of the heat transmission pipes are simultaneously employed.  
     CONSTITUTION: Helical coil heat transmission pipes 1, 1 are supported by the supporters 4a and 4b, e.g. which are established on the other circumference of the inner drum 2 with equal interval while the supporter 4a fixes the heat transmission pipe 1 rigidly, and the supporter 4b restrains the movement of the heat transmission pipe 1 to its axial direction alone and does not restrain the movement to its radial direction. Under this constitution, supporter 4a disposes the thermal stress preventing the concentration of stresses into a locality caused by the thermal expansion of the heat transmission pipe 1 while the supporter 4b does not restrain the thermal expansion of the said pipe 1 but contributes to increasing the natural frequency of the said pipe 1. Accordingly, thermal stress of the heat transmission pipe can be decreased without reducing largely the natural frequency of the pipe.

Title: Formation of polycide pattern
Inventor: SHIOTANI YOSHIMI
IPC: H01L29/78
Filed: 1987-05-14
Abstract: PURPOSE:To prevent the breakdown strength from deteriorating due to the occlusion of fluorine in an insulating film at the lower part of a wiring part by a method wherein, when a polycide wiring part is formed, an annealing process to lower a resistance value of a refractory metal silicide layer is executed while a silicon oxide layer is applied to the refractory metal silicide layer. CONSTITUTION:A gate oxide film 2 is formed on an Si semiconductor substrate 1; then, a poly-Si layer 3 is grown on the film; then, ions are implanted into this poly-Si layer 3. Then, a WSix layer 4 is grown on the poly-Si layer 3 by a CVD method; an SiO2 film 5 is deposited on the layer. Then, during an annealing process the WSix layer 4 is heated and crystallized to make a resistance value low. During this crystallization in the annealing process, F hardly invades into the gate oxide film 2 via the poly-Si layer 3; it is possible to prevent the breakdown strength of the gate oxide film 2 from deteriorating due to a phenomenon that one part of oxygen constituting this gate oxide film is substituted for F.
