Title: Surface acoustic wave device and manufacture thereof
Inventor: NAKAGAWA MASATOSHI
IPC: H03H9/02
Filed: 1999-09-02
Abstract: PROBLEM TO BE SOLVED: To increase the contact of interdigital electrodes with a piezoelectric substrate by stacking at least one interdigital electrode formed on the piezoelectric substrate on a 1st metal thin film as a base and providing a 2nd metal thin film, which consists principally of tantalum and is made into α-tantalum at least partially. SOLUTION: On the piezoelectric substrate 2, an interdigital electrode(IDT) electrode) is formed of a comb-tooth electrode. An electrode finger 3a of the comb-tooth electrode has a 2nd metal thin film (tantalum thin film) 5b formed of tantalum on a 1st metal thin film. Here, the 1st metal thin film is formed of a laminated metal film in two-layered structure and a lower tungsten thin film 5a1 and an upper titanium thin film 5a2 are stacked. The tantalum thin film 5b is formed on the titanium thin film 5a2 and made into α-tantalum. The specific resistance of the IDT electrode is therefore reduced to improve the insertion loss.

Title: Detecting method of defective p-n junction in ic
Inventor: MORIKAWA HISASHI
IPC: H01L21/66
Filed: 1983-12-28
Abstract: PURPOSE:To detect a defective p-n junction through visual inspection by electrolytically plating the surface of an IC semiconductor substrate and forming electroplating layers in specific thickness on the surfaces of each p-n junction before electrodes are formed on the p-n junctions in the surface of the IC semiconductor substrate. CONSTITUTION:When a semiconductor substrate S is dipped in an electrolyte so that the surface side is opposed to an electrode A and voltage is applied while using the substrate S as another electrode, currents flow through an n type region being in contact with p type regions through diffusion layers, and electroplating layers are shaped to the surfaces of the p type regions. In this case, the diffusion potential of a defective p-n junction is lower than excellent p-n junctions, currents more than other sections flow, and the thick electroplating layers are formed. The difference of film thickness can be viewed as the difference of colors when film thickness extends over approximately 1mum or less in the electroplating layer. Accordingly, the semiconductor substrate S is pulled up once from the electrolyte when the plating layers reach to predetermined thickness of approximately 1mum or less, and the section of color irregularity can be regarded as the defective p-n junction through visual inspection.

Title: Slip control device for vehicle
Inventor: TEJIMA MAKOTO
IPC: F02D45/00
Filed: 1989-09-26
Abstract: PURPOSE:To prevent an engine output from excessively decreasing, when the atmospheric pressure is decreased, or on the ground of its decrease while suppressing an excessive slip of a drive wheel by correcting a slip control value to be optimized corresponding to a difference of the atmospheric pressure. CONSTITUTION:A slip value for a road surface of a drive wheel A in a vehicle is detected by a means B. While when the detected slip value is not less than a predetermined value, a means D for adjusting a load of an engine C is controlled by a means E by taking priority of accelerator operation with generated torque of the engine reduced. Further the atmospheric pressure is detected by a means F. When the detected atmospheric pressure is in a low value, as compared with when it is in a high value, a control value by the above described means E is corrected by a means G in a direction of decreasing a degree of reducing the generated torque in the engine C. Thus while suppressing an excessive slip of the drive wheel A, an excessive decrease of an output of the engine C is prevented when the atmospheric pressure is decreased.

Title: Reducing device of stress peak in anchor containing so-called "fir tree-shaped leg"-shaped root section of turbine blade
Inventor: PIEERU BURUSHIE
IPC: F01D5/30
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To reduce stress peaks in turbine blade anchoring by outlining cutouts on the extrados side of a blade root such that their clearance for root mounting in a groove on the extrados side is not uniform and rather they include at least one zone in which the clearance varies. SOLUTION: In a portion of a root on an extrados side, cutouts 3A to 3D form clearances J1 to J4 with the corresponding wall of a groove 6. The clearances J1 to J4 do not exist over the entire length of the cutouts 3A to 3D. The clearance J2 varies in the direction of a stress peak, or the root moves to the relief edge as the clearance J2 increases. If an excessively high stress peak occurs on the side corresponding to the abut edge of the root, if necessary, the same measures can be taken on the side in question. For such clearance arrangement, the cutouts 3A to 3D are cut into a prescribed shape. During turbine rotation, it is thus possible to reduce stress peaks generated in the root and in a disk conforming to the cutouts 3A to 3D.
