Abstract: A cost estimate generating system comprises a pocket type computer which includes a control schedule which sequentially requests data relating to the number of damaged panels, the number of damaged sections of each of the panels, the damage degree or repair difficulty degree, the presence or absence of scratches, the length and depth of any scratches, the type of paint work (e.g. metallic or solid finish, the number of different colors or tones) and the current labor rate (cost per man hour); and calculates the amount of work, the amount of paint required and the cost of the paint based on the data input.

Abstract: A semi-continuous vacuum heat-treating furnace of two-chambers and one-door type is composed of a vacuum heating chamber which includes a heating element and a heat insulation material, both being stable in chemical property and strength in vacuum condition and atmospheric pressure at high temperature, a cooling chamber which is associated with the vacuum heating chamber, and an intermediate vacuum door which separates the vacuum heating chamber and the cooling chamber from each other.
