Title: Thin glazed substrate
Inventor: TSUZUKI MASAJI
IPC: C04B41/86
Filed: 1992-10-30
Abstract: PURPOSE:To reduce the warpage of a thin glazed substrate having <0.5mm thickness. CONSTITUTION:A glazed layer is formed on the whole surface of the alumina substrate having <=0.5mm thickness so that the thickness after firing is <=20mum by using a glazing paste consisting of a glazing material free from alkali metal and lead and having -15% to +5% average thermal expansion coefficient between room temp. and the glass transition temp. to that of the alumina substrate. As a result, the warpage of the thin glazed substrate is reduced to below that of the conventional glazed substrate. And the glazed substrate is electrochemically stabilized since the glazed layer does not contain alkali metal and lead. Then the thin glazed substrate is suitable for small sized, high density and high precision chip parts or the like.

Filed: 1989-12-07
Abstract: PURPOSE:To display distinctly the actual amount of a refrigerant packed by specifying the total amount of the refrigerant packed at a point of time when the dropped rate of a shell temperature in a low-pressure shell type compressor reaches a preset value or below as an optimum value, disposing an operation means for computing the rate of the refrigerant packed in a freezing cycle on the basis of the optimum value thus specified, and also disposing a display means for displaying the computed value. CONSTITUTION:A refrigerant is packed from a refrigerant packing port 12, and a shell tempera ture T deg.C in a low-pressure shell type compressor at a point of that time is detected by a temperature sensor 10. Subsequently, a microcomputer 11 judges whether the dropped rate of the shell temperature T deg.C with respect to a predetermined amount DELTAM of the refrigerant increased is not more than a preset value s, and, in the case where the judgement result indicates No, DELTAM of the refrigerant is packed again. Thus, when the amount of the refrigerant packed in a freezing cycle is increase, so that the shell temperature T deg.C is stabilized at a fixed level, the total amount SIGMAM of the refrigerant packed at a point of that time is speci fied as the optimum amount of the refrigerant to be stored in a storage means. The rate C of the refrigerant packed is then computed by applying the formula of C=(SIGMAM+kDELTAM)/SIGMAM on the basis of the total amount SIGMAM of the refrigerant packed and the amount kDELTAM of the refrigerant additionally packed thereafter, and the computed value thus obtained is numeri cally displayed on a display unit 13.
