摘要： PURPOSE:To apply a thick titanium carbide film to a substrate in good close adhesiveness, by adjusting the internal stress of the titanium carbide film by changing voltage applied to the substrate corresponding to the accumulated film thickness of titanium carbide. CONSTITUTION:In applying a thick titanium carbide film to a substrate by a physical vapor deposition method, constant voltage of minus 150-250V is applied to the substrate at the beginning of coating to perform the positive draw- in of a titanium ion and the close adhesiveness of the substrate with the titanium carbide film is enhanced. When the titanium carbide film having good close adhesiveness reaches several mum, voltage to be applied is gradually lowered until 1-2mum is further accumulated to be brought to minus 5V or less. Thereafter, voltage is constantly held at minus 5V or less until vapor deposition is finished to form the objective film thickness. By this method, the titanium carbide film with a thickness of several mum or more is formed on the substrate in good close adhesiveness.

摘要： PURPOSE:To inspect vacuum leakage at a connection part between the port of the internal wall of a vacuum container and the vacuum container easily and securely by blocking a part, communicating with the port of the internal wall, by a detachable lid and by evacuating the port in this state for the vacuum leakage inspection. CONSTITUTION:A port 6 is welded to a vacuum container 2 at a weld zone 8a. Further, a lid 10 is added to the internal wall part of the vacuum container 2 to block the opening part of the port 6, and welded to the vacuum container 2 at a weld zone 11. Then, the port 6 is sealed hermetically to the inside of the vacuum container 2 and a vacuum pump and a vacuum leakage inspecting apparatus are connected to a flange part 9 to evacuate the port 6, thereby inspecting vacuum leakage easily at the fitting part between the port 6 and vacuum container 2, i.e., the weld zone 8a. After the inspection, the lid 10 is removed at the weld zone 11 to complete the port 6 communicating with the inside of the vacuum container 2.

摘要： PURPOSE:To reduce the heat generation in print circuit substrates when drilling holes through them at a high speed and also avoid smear developing around the holes, by forming a plural number of margins on the ridges along the two cutter grooves of a twist type drill. CONSTITUTION:Along the ridges of the cutter grooves 5 that run from the drill tip 1 to the drill stem 6, margins 4 are provided, starting from the lip corner 3. The margins 4 are not formed on the groove ridges continuously to the attachment portion thereof. At the intermediate portions the margins are omitted. In other words, in this construction a plural number of margins are formed along the ridges of the cutter grooves 5, giving intermittent cutting. Accordingly, the friction heat is not continuously generated and the overall heat generation can be reduced.
