A peak holding means 9 holds the max. value among pixel outputs in one scanning. A reset time control means 10 provides the reset times t11, t12,... corresponding to a thermometric range and also provides the upper limit value eH and the lower limit value eL and, when the max. value of the sensor 3 is the value eH or more, the reset times are made long and, when the max. value is the value eL or less, the reset times are made short and the output of the sensor is always set so as to be present between the values eH, eL. Then, reset time data is sent to a linearizing means 8 which in turn selects a linearizing table according to a thermometric range (A-C).

Title: Dipping liquid cooling semiconductor element
Inventor: YAMADA MITSUTAKA
IPC: H01L23/44
Filed: 1988-12-13
Abstract: PURPOSE:To suppress rapid increase in element temperature and prevent breakdown of the element by providing one or more protrusions of a specific height consisting of metal on the rear surface of the element. CONSTITUTION:One or more protrusions which are 2mm or more in height consisting of metal are provided on the rear surface of an element. Even when a film boiling occurs on the surface of the element, air bubble of the film boiling is 2mm or less so that the upper part of protrusion protrudes from air bubble of film boiling if the height of a protrusion 5 exceeds 2mm. In this case, since the element is cooled through protrusion, the element temperature does not rise and danger for element breakdown is reduced drastically. Thus, calorifit value of element can be set to a higher value than as compared before. The diameter of protrusion may be phi 0.5-1.0mm and the sectional area of protrusion may be approximately 1/500 to 1/100 as compared with the element area.
