Title: Variation rate detection method for analog information
Inventor: KUMAGAI HIDEMI
IPC: G05B21/02
Filed: 1986-09-10
Abstract: PURPOSE:To detect both long-period variation and short-period variation by comparing a sampled value obtained at a short period with a comparison reference value obtained at a period which is an integral multiple of said period, and obtaining variation rate information. CONSTITUTION:A CPU 3 reads a process value out of an interface 1 at every constant period. Then the current sampled value and a count value of the number of times of sampling are stored in a RAM 5 and the current sampled value is compared with the comparison reference value stored in the RAM 5 to check whether or not the absolute value of the difference between the both exceeds a prescribed variation rate limit value. Then when the absolute value exceeds the limited value, the variation rate is diagnosed as an abnormal value to output an alarm-on signal and when not, it the normalcy of the variation rate is judged to output an alarm-off signal. Then, the comparison reference value is updated into the current sample value at a reference value update period and the new comparison reference value is stored in the RAM 5. Consequently, the rate from long-period variation to short-period variation is securely grasped at every reference value update period and reflected upon the variation rate diagnosis.

Title: Semiconductor device
Inventor: AYABE TOSHIJI

Filed: 1986-09-09
Abstract: PURPOSE:To keep a resistance value used in a circuit constant irrelevant to a temperature by a method wherein a diffusion resistance with a positive temperature coefficient and a polycrystalline silicon resistance with a negative temperature coefficient are formed in the main surface of a semiconductor and connected in series or in parallel. CONSTITUTION:After a diffusion resistance 1 is formed, a polycrystalline silicon resistance 9 are formed and connected to the diffusion resistance 1 in series through contact windows 2 with aluminum wirings 8. If the temperature coefficient of the diffusion resistance 1 is alpha (alpha>0), the temperature coefficient of the polycrystalline silicon resistance is -beta (beta>0), a reference temperature is T0, the resistance value of the diffusion resistance 1 at that time is R1, the resistance value of the polycrystalline silicon resistance 9 is R2 and the equivalent resistance value when the diffusion resistance 1 and the polycrystalline silicon resistance 9 are connected in series is R0, R0 is expressed by R0=R1+R2. If the equivalent resistance at a temperature T is R, R is expressed by R=R1+R2+(alphaR1-betaR2)(T-T0). In order to make the resistance value R constant irrelevant to the temperature, the resistance values R1 and R2 are so selected as to conform to alphaR1-betaR2=0. By designing the diffusion resistance and polycrystalline silicon resistance 9 like this, the influence of the temperature upon the resistance value can be eliminated.

Abstract: PURPOSE:To miniaturize the vaporizing part by using a single motor even if twin burners are employed by disposing a rotor at the end of respective motor shafts, and disposing a vaporizer so that is surrounds a slinger plate disposed at the end of the rotor. CONSTITUTION:When liquid fuel is supplied to a rotor 19 and reaches a slinger plate 20 via the conical surface of the rotor 19 which is rotated by a motor 15, the fuel is atomized and scattered to be vaporized on the vaporizing surface of a vaporizer 24. The combustion primary air passes through a primary air passage 16, and part of its leaves a purge air hole 28 as purge air and the rest enters from a carrier air hole 27 into a mixing chamber 26 to smoothly flow upwardly as it carries and mixed with the vaporized gas to a burner 29 where the mixture is ejected from flame hole plate 30 for combustion. Meanwhile, the combustion secondary air passes through a secondary air passage 31 to be ejected out of a secondary air port 32 to hit the flame formed above the flame hole plate 30, causing a short flame length for a high load combustion. Since only one motor 15 is required to rotate the slinger plate 20 for the twin burners 29, the vaporizing part can be miniaturized.

Title: Refrigerator oil composition
Inventor: MITSUFUJI MUNEO
IPC: C10N30/18
Filed: 1982-12-06
Abstract: PURPOSE:To provide a lubricating oil composition containing a defoamer which prevents foaming when the composition is used at a low viscosity as refrigerator oil, prepared by adding trifluoropropylmethylpolysiloxane to a base oil consisting of a specified synthetic oil. CONSTITUTION:The lubricating oil composition is prepared by adding 0.1- 30ppm trifluoropropylmethylpolysiloxane to a base synthetic oil consisting of paraffinic, nephthenic or mixed mineral oil and olefin and having a viscosity of 3-15cSt at 40 deg.C. Dimethylpolysiloxane having a viscosity of 1X10<3>-1X10<4>cSt has so far been used as defoamer for refrigerator oil, but as the viscosity of the refrigerator oil is reduced, it becomes highly soluble in the oil and loses its foaming preventive power. The trifluoropropylmethylpolysiloxane shows an excellent foaming preventive effect in a state in which the siloxane molecules are incorporated into the refrigerator oil, as foams disappear through destruction of a part of intermolecular force of a hydrocarbon which constitutes the refrigerator oil.
