Title: Temperature measuring method
Inventor: SHIRAKAWA HIDEKAZU
IPC: H01L21/027
Filed: 1989-03-31
Abstract: PURPOSE:To eliminate the need for the setting of emissivity and to accurately measure the temp. of a body in a non-contact state by respectively measuring the radiant quantities in the plural absorption peak wavelengths obtained from the absorptivity of the body to be measured. CONSTITUTION:IR detectors 11 and 12 for detecting the IR emitted from the photoresist 2a coating the surface of a semiconductor wafer 2 placed on a heating plate 3 are provided. The filters 11a and 12a selectively transmitting the wavelengths lambda1 and lambda2 different from each other are provided to the detectors. The outputs of the detectors 11 and 12 are inputted to a temp. calculator 13 through amplifiers 11c and 12c respectively having gains K1 and K2. The monochromatic emissivities Elambda1 and Elambda2 at the wavelengths lambda1 and lambda2 are obtained by the gains K1 and K2 from the previously measured absorption spectrum of the body to be measured, and the setting is controlled to K1/K2 Elambda2/Elambda1. Since the emissivity of a body is equal to the absorptivity, a measurement with a little effect of the IR radiation from the background of the body to be measured can be realized by measuring the high-absorptivity wavelength of the body.

IPC: H04N1/419
Filed: 1984-04-25
Abstract: PURPOSE:To decide accurately the picture quality of a reception picture by estimating how many lines of data are lost from a reception data depending on the interval of end of line codes before and after an error line. CONSTITUTION:A corresponding run length RL or an end of line code EOL is obtained from the reception code, the code bit number required for decoding is integrated in an LENGTH of a memory 5 and whether or not the decoded result is the EOL code is decided. When the code is not the EOL code, the obtained RL is added to TOTAL. On the other hand, when the code is the EOL code, the total of the decoded RL of one line is decided whether it is 1,728 or not and when the preceding line is not the error line, the content of the LENGTH is transferred to a BEFORE to complete the decoding of one line. On the other hand, when the line is the error line, a larger content between the content of the BEFORE and the content of the LENGTH is used as a UNIT, the content of the ERRORBIT is divided by the UNIT and the decoding of one line is finished.

Title: Suction equipment for internal combustion engine with exhaust turbo-charger
Inventor: NOHIRA HIDETAKA
IPC: F02B37/00
Filed: 1979-07-02
Abstract: PURPOSE: To greatly accelerate the combustion speed of an engine under low load by providing a secondary throttle valve in each suction passage running behind a primary throttle valve, and an auxiliary suction passage for bypassing the secondary throttle valve.  
     CONSTITUTION: Under low load operation where a primary throttle valve 25 opens little, the pressure in a suction duct 24 comes approximately equal to the atmospheric pressure. On the other hand, the pressure in a suction manifold 22 downstream the primary throttle valve 25 is greatly reduced to a negative pressure, thereby causing each secondary throttle valve 26 to be closed completely as shown by a dotted line 26a. Branch pipe 30 forcedly leads air fuel mixture at a high speed into appropriate combustion chambers 5, in each of which powerful swirl is generated as indicated by an arrow W. Each swirl greatly accelerates the combustion speed under low load. Under a high load operation, as each of the secondary throttle valve 26 is kept nearly closed at a position 26b, knocking can be prevented.

IPC: B22F9/08
Filed: 1978-07-10
Abstract: PURPOSE: To suppress absorption of O 2  gas into molten steel and make possible underwater casting which has hitherto been considered difficult to be put to practical use by containing 1 to 35wt% of the specific organic material in the water used in the underwater casting method of molten metal.  
     CONSTITUTION: Molten steel 2 from a ladle 1 reaches the copper-made casting mold 5 in a water vessel 7 and organic material (preferably one which is water soluble and of low boilding point) such as methyl alcohol or the like which produces reducing gases such as CO and CH 4  by decomposing by the effect of the heat retained in the molten steel 2 is beforehand contained in cooling liquid 4. Since the O 2   through decomposition of steam produced at the time when the molten steel 2 is cast in water is consumed by the reducing gases which the foregoing organic material produces, the rate of O 2  absorption in the molten steel is reduced and the underwater casting of high quality of less O 2  contents is obtained.

Filed: 1981-05-30
Abstract: PURPOSE: To make unload control attainable, by making up an opening spanned between a fluid suction chamber and a central chamber on a plate body of a fixed scroll casing member and distributing a switch control valve to this opening.  
     CONSTITUTION: A fluid suction chamber 132 is made up between an inner wall surface of a cuppy housing 10 and a scroll body 22 of a movable scroll casing member 20. On a bottom plate 12 of the housing 10, an opening 5 spanning a fluid suction chamber 132 and a central chamber 122 is made up and at the same time a switch control valve 1 to be coupled with a plunger 4 of a solenoid 3 is arranged to be set up via a spring 2. When the opening 5 is in a state of open, a by-pass circuit 6 which inter connects the fluid suction chamber 132 and a fluid discharge chamber 123 through is formed, that is, compression stroke becomes released and this fact may dispense with a job of compression for the scroll type fluid system, decreasing a loss of energy. Like this, when unload functions are given to the control valve, substantially compressing operation is as good as unnecessary indeed.

Abstract: PROBLEM TO BE SOLVED: To suppress packet retransmission of a communication of low priority in the congestion. SOLUTION: A recording managing means 13 manages the frequency of retransmission showing how many times retransmission is allowed, packet by packet.

Filed: 1984-04-25
Abstract: PURPOSE:To simplify measurement procedure, and to perform data processing and to use a nonreflection type as a wave source and a detector by allowing a reflection coefficient measuring instrument to function as a detector for a transmitted wave. CONSTITUTION:The wave source 4 of a reflection coefficient measuring instrument 7 is turned on and the wave source 11 of a reflection coefficient measuring instrument 14 is turned off. The reflected wave indicator 6 of measuring instrument 7 indicates a reflection coefficient u1 when a component side is viewed from an input surface 1 through a directional coupler 5. Further, the measuring instrument 14 functions as the detector for a transmitted wave because the wave source 11 is off, and a reflected wave indicator 13 indicates a transmission coefficient I2. Then, the wave source 4 is turned off and the wave source 11 is turned on; the reflection coefficient measuring instrument 14 indicates a reflection coefficient u2 when a component 3 to be measured is viewed from the input surface 2 and the measuring instrument 7 indicates a reflection coefficient I1. Then the component 3 is removed and only the wave source 4 or 7 is turned on, and then the measuring instruments 6 and 14 indicate a reflection coefficient to the other measuring instrument and detection outputs to light from the wave sources 11 and 4. Those data are processed to measure the transmission parameter of wave motion.
