Title: Temperature measuring instrument for semiconductor integrated circuit
Inventor: TOYOOKA TAMOTSU
IPC: G01K7/00
Filed: 1989-11-10
Abstract: PURPOSE:To accurately measure the surface temperature of a chip by using a P-N junction diode which is parasitic between terminals of an IC as a diode for temperature measurement. CONSTITUTION:A signal generator 26 is turned off to make the IC 10 inactive and the potential difference between the terminals 36 and 38 is measured by supplying a specific forward current from a constant-current source 22 to the P-N junction diode 12 at various ambient temperatures, thereby determining the temperature coefficient of the diode 12. Then the signal generator 26 is turned on to activate the IC 10 and turned off when the chip surface temperature becomes balanced; and the constant forward current is supplied to the diode 12 right after that and the potential difference between the terminals is measured to estimate the temperature in operation from the potential difference between the terminals of the diode 12 which is not in operation, the quantity of variation in the terminal potential difference, and the temperature coefficient. Therefore, a means for temperature measurement need not be provided newly and the chip surface temperature can easily and accurately be measured.

Filed: 1996-11-06
Abstract: PROBLEM TO BE SOLVED: To decrease the information content when the same image data are encoded at the same level of picture quality by adding or subtracting the existing range of the original pixel value to and from an estimation error if the absolute value of the estimation error exceeds the half of the said existing range. SOLUTION: A blocking part 11 divides a 1-frame image of input image signals into a prescribed number of blocks and outputs the pixel data on every divided block to a memory 12 and an adder 13. The memory 12 successively stores the 1-frame preceding image signals of video signals inputted to an image encoder 10. The adder 13 calculates the difference between the pixel value of every block of each frame of video signals received from the part 11 and the value of the 1-frame preceding corresponding pixel that is sent from the memory 12 and then converts the current frame pixel value into the value that is estimated based on the 1-frame preceding image.  An encoding part 15 and a quantization part 16 encode the pixel data on the image data corrected at a difference correction part 14 in every block and then integrate the data on every block which are encoded at a framing part 17 to generate and output the encoding data on each frame.

Title: Circulation purifying device for hot bathing apparatus
Inventor: FUMOTO MASASHI
IPC: F24H9/00
Filed: 1996-10-16
Abstract: PROBLEM TO BE SOLVED: To provide a circulation purifying device for a hot bathing apparatus to peel deposit and microorganisms adhered to the moving parts of a float switch and a water flow direction control valve and maintain the function of the moving part. SOLUTION: A control device 50 periodically drives the moving part of a float switch 28 and a water flow direction control valve. In this case, a control means discriminates whether abnormality exists in a moving part by monitoring a signal from a position detecting means 52 for the float switch 28 and the water flow direction control valve, and displays an alarm when abnormality is present and stops operation. As noted above, since microorganisms adhered to the periphery thereof are moved by periodically moving the moving part and peeled by a water flow, the deposit and the microorganisms hardly continuously grow and adhesion hardly occurs. Even when adhesion occurs, since operation of the moving part is periodically confirmed, abnormality is detected at an early stage and a hazard is prevented from occurring.

Title: Control of main steam pressure in boiler
Inventor: KATSUKI KENJI
IPC: F22B35/00
Filed: 1993-11-25
Abstract: PURPOSE:To control the flow rate of the feedwater to a boiler in total by adding to a main-steam pressure deviation signal a temperature deviation signal obtained by deducting a preliminarily specified set value from the main-steam temperature signal of the boiler. CONSTITUTION:A deviation signal obtained by deducting a set main-steam temperature value 9 from the main-steam temperature signal 8S of a boiler is prepared by a subtracter 10. After multiplying the result by a gain 11a and cutting off the excesses of the signal over a certain range by an upper-and-lower value limiter 12a the result is added to a main-steam pressure deviation signal by an adder 13a. Consequently, when the main-steam temperature deviation is large, the feedwater flow rate in total is so controlled as to make it smaller, that is, in the case of an excess of the main-steam temperature over a set value, the control makes the feedwater flow rate to the boiler increase in total, so that the main-steam temperature lowers to the set value. Conversely, in the case of lower of the mainsteam temperature below the set value, the control makes the feedwater flow rate to the boiler decrease in total, so that the main- steam temperature rises back to the set value.
