Title: Heat dissipating apparatus with variable heat transfer rate
Inventor: MIYAGAWA SHINICHI
IPC: H01L23/42
Filed: 1992-02-06
Abstract: PURPOSE:To increase heat transfer rate of a heat dissipating apparatus, by forming an air gap in the inside of its body, and filling the air gap with grease having a temperature region wherein a heating element normally operates. CONSTITUTION:The heat generated from a heating element 5 fixed to a heat dissipating apparatus body 1 is conducted to a heat dissipating main body in contact with a heat generating element 5, and dissipated in the surrounding air from heat dissipating fins 2 via the grease 4. In the case of heat dissipating apparatus with a variable heat transfer rate, as shown by a continuous line 9, the heat transfer rate alphaH of the whole part of the heat dissipating apparatus becomes small when the surrounding air temperature TA is lower than the melting point of the grease 4, which is turned into liquid by phase change at a temperature higher than the melting point. The heat is conducted by convection as well as by conduction, so that the heat transfer rate of the heat dissipating apparatus can be improved.

IPC: G01B11/03
Filed: 1993-03-18
Abstract: PURPOSE:To properly position a washing brush and a drying nozzle thereby to improve the washing efficiency and facilitate saving of labor, by recognizing the shape of a vehicle body correctly. CONSTITUTION:While a gate 10 of arm inversed U shape of a car washer is proceeded in the longitudinal direction astride a vehicle body 9, a washing brush or a drying nozzle is positioned in conformity with the contour of a cross section of the center of the vehicle body 9 for washing and drying. A distance sensor 1 is set at the center of an upper side of the gate 10 to measure the distance downward in the vertical direction, i.e., to the upper surface of the vehicle body 9 along the central longitudinal direction. Accordingly, the contour of a side section of the vehicle body 9 is detected. An X detecting part 4x obtains X coordinates=V.Ti at a time point Ti because the gate 10 moves at a velocity V. A Z detecting part 4z obtains Z coordinates of the contour of the upper surface of the vehicle body 9 from the output of the distance sensor 1. Since Y coordinates are a constant value A, a Y detecting part is not provided in the apparatus. The set of the X and Y coordinates at the time point Ti is stored in a data storing part 5 as a vehicle shape data.
