Abstract: PURPOSE:To adjust the contrast of interference fringes to the optimum state in response to the material and the like of a roof surface by rotating polarizing plates, which are provided in front of an image receiving means. CONSTITUTION:The diameter of the coherent parallel luminous flux emitted from a light source 11 is expanded through a beam expander 12. The luminous flux is reflected from a half mirror 13. A part of the luminous flux is reflected from a surface 14a and becomes a reference wave. The remaining part is reflected from a roof surface 30 and becomes a wave to be detected. The interference fringes generated by the interference of the wave fronts are detected with an image receiving element 15 through an observing lens 16 and converted into the electric signal indicating the variable density of the interference fringes. At this time, the amount of the transmitted light can be changed by rotating polarizing plates 40 and 41. The contrast of the interference fringes can be optimally adjusted in response to the material of the roof surface. The variable density data of the interference fringes from the element 15 are binary-coded with an image processing circuit 17 and displayed on an interference observing monitor 18. The data also inputted into a phase detecting means 21, and the amount of the phase for every unit measuring region is detected.

Title: Cooling fin structure
Inventor: YOMO KUNIO
IPC: H05K7/20
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To form a cooling structure excellent in cooling efficiency having no possibility of causing a damage thereto even if power semiconductor devices in different tolerances are fitted to both sides of the structure by making intervals between the cooing fins having two metallic substrates. SOLUTION: This cooling fin structure 1 is formed by abutting extruded aluminum substrates 2, 4 against each other and then engaging both outer sides parts 7, 9 with each other as a fixing leg 10. Next, the intervals 11 are made between the cooling fins 6, 8 by making the lengths of the cooling fins 6, 8 shorter than that of both outer side parts 7, 9. In such a constitution, when a power semiconductor device is fitted to the surfaces 2a, 4a of the extruded aluminum substrates 2, 4, the generated heat is conducted to the cooling fins, 6, 8 through the extruded aluminum substrates 2, 4 to be radiated. Through these procedures, even if the packaged semiconductor devices heat up differently, the heats can be efficiently radiated without conducting from the higher temperature substrate to the lower temperature substrate.

Filed: 1996-12-14
Abstract: PROBLEM TO BE SOLVED: To obtain good brazeability with a small quantity of a brazing filler metal by locally fusing a joining member with using a hyper-eutectic Al-Si alloy powder essentially consisting of Si for a brazing filler metal when brazing aluminum or aluminum alloy.

Title: Throw-away tip for corner cutting
Inventor: TAKAHASHI ISATO
IPC: B23C5/20
Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To make both cutting edges well-balanced in knife-edge strength so that the sharpness of a main cutting edge is not lowered and a chip is hardly caused by the progress of abrasion of an auxiliary cutting edge by relating a land width and a face angle of the main cutting edge to a land width and a face angle of an auxiliary cutting edge in the right-angled section of the cutting edge in such a manner as to satisfy a specified expression. SOLUTION: In the blade rignt-angled section of a throw-away tip for corner cutting, a land width (a) and a face angle α of a main cutting edge are related to a land width (b) and a face angle βin such a manner as to satisfy the expression I. The cutting performance of a tool itself is dominated by the outer peripheral main cutting edge, and the auxiliary cutting edge always rubs the bottom of a material to be cut to form a cutting surface. Accordingly, if b>1.3a, the effect of increasing the knife edge strength due to increase in the land width is small, and if b>2.5a, the effect of the face angle α is made smaller, and the land part acts intact as a cutting face, so that the sharpness is lowered, the abrasion of the auxiliary cutting edge part is more promoted, and chatter is easily caused by the increase in cutting resistance. Accordingly, the expression I is established. α>β is intended for increasing the strength of the auxiliary cutting ege, and the land width (a) is easily selected.
