摘要:
An infrared sensor unit has a thermal infrared sensor and an associated semiconductor device commonly developed on a semiconductor substrate. A dielectric top layer covers the substrate to conceal the semiconductor device formed in the top surface of the substrate. The thermal infrared sensor carried on a sensor mount which is supported above the semiconductor device by means of a thermal insulation support. The sensor mount and the support are made of a porous material which is superimposed on top of the dielectric top layer.

An abdomen width determiner determines an abdomen width value of a human subject. A memory stores a correlation between abdomen width values and waist circumferences of human beings. A waist circumference calculator calculates a waist circumference of the human subject on the basis of the abdomen width value determined by the abdomen width determiner and the correlation stored in the memory. The correlation stored in the memory may be expressed by the following regression formula: Y=aX+b where “Y” is a waist circumference of a human being, “X” is an abdomen width value of a human being, and “a” and “b” are constants.
摘要:
A method of manufacturing a semiconductor device. In this method, a concave portion is formed in one surface in the thickness direction of a primary base plate comprising a semiconductor substrate with a relatively large thickness dimension. Then, through-holes are formed by a reactive-ion etching process using as a mask an opening formed in an oxide film provided on the other surface in the thickness direction of the primary base plate. The opening has a narrow width in a region corresponding to the concave portion and a wide width in the remaining region. Thus, respective times necessary for the wide-width through-hole to penetrate through the primary base plate and necessary for the narrow-width through-hole to reach a bottom surface of the concave portion can be approximately equalized to complete the common etching process of the wide-width through-hole and the narrow-width through-hole approximately simultaneously.

摘要:
In a load transfer mechanism which transfers load to a load cell that constitutes a Roberval mechanism, a load transfer member has at least an area right above a load cell mounting section in the top surface thereof as a concave surface area formed to be lower than the remaining area of the top surface thereof so that it does not contact a cover member. Thus, if the barycentric position of the load of an object to be weighed placed on the cover member, regardless of whether the load is concentrated load or divided load, the load transfer mechanism can reduce the difference of the influence of deflection of the load transfer member or moment imposed on the load, transfer given load to the load cell through the load transfer member and decrease a span error produced by the load position of an object to be weighed.

A shape memory alloy consists of a three element alloy of nickel-titanium-copper which is formed as being subjected to a cold working and to a heat treatment at a temperature below recrystallization point of the alloy for storing the shape, the alloy being thereby improved in operation stability and reliability even after repetitive operation and made wider in environmental temperature range for use therein of the alloy.

A joint material that is improved in arc-proof characteristic, fusion-proof characteristic, and consumption-proof characteristic. The joint material contains silver, lithium oxide and one selected from the group consisting of aluminium oxide, calcium oxide, magnesium oxide, and silicon oxide. Furthermore, one selected from the group consisting of iron, nickel and cobalt may be contained as an additional component in the joint material. Such joint material is produced by a method of oxidizing the silver alloy containing lithium and one selected from the group consisting of aluminium, calcium, magnesium, and silicon, with the composition ratio of 0.1-3 wt % for lithium, and 0.01-1 wt % for aluminium, calcium, magnesium, and silicon, respectively, in quantitive conversion to metal or by a method of oxidizing the silver alloy containing, in addition to the components mentioned above, one selected from the group consisting of iron, nickel, and cobalt, with the composition ratio of 0.05-1 wt %. In either of those methods, the oxidization mentioned above is performed through internal oxidation in order to disperse each of the foregoing oxides in silver.
