Title: Manufacture of elastic surface wave device
Inventor: KISHI SHIYOUICHI
IPC: H01L21/027
Filed: 1984-05-22
Abstract: PURPOSE:To realize the production of high-precision interdigital electrodes by a method wherein the width of a pattern corresponding to equi-distantly arranged interdigital electrodes is caused to be smaller than the distance between the interdigital electrodes. CONSTITUTION:The device of this design is constituted of a piezoelectric substance 1, electrode forming members, resist 3, glass mask 4 and a pattern 8, and the pattern 8 is formed to be smaller in width than the distance between interdigital electrodes. That is, on the glass mask 4, the distance B between interdigital electrodes is formed to be larger than the width A' of the pattern 8. It follows therefore that, when the pattern 8 wherewith the resist 3 is in close contact is exposed to rays 6 projected by a UV illuminator, the quantity of diffracted rays 61 is far smaller than the quantity of rays 6 directly hitting the resist 3 without being diffracted. The resist 3 therefore is exposed to the rays 6 as hatched in the figure (c). The entirety of the resist 3, except the portion corresponding to the pattern 8 and the interdigital electrodes 7, is exposed to the UV energy. A combination of the exposed resist 3 and the piezoelectric substrate 1 is subjected to development and etching, for the formation of the interdigital electrodes 7.

Title: Ceramic cutting tool
Inventor: HARA AKIO
IPC: B23B27/16
Filed: 1986-05-06
Abstract: PURPOSE:To prolong tool life and enable highly efficient machining by forming a diamond sintered body or diamond monocrystal body of 1mm or less in thickness and by mounting it on a base metal with the cutting edge section overhanging 0.1mm of more from the base metal. CONSTITUTION:A tip 1 made of a diamond sintered body or artificial diamond monocrystal body of 1mm or less in thickness is formed. This tip 1 is coated with TiC of about five(5) micron meters in thickness by means of CVD(chemical gaseous phase vapour deposition method) to be brazable. In the next step, this tip 1 is brazed to a base metal 2 with a cutting edge overhanging by 0.1mm or more in overhanging quantities (x) and (y). These overhanging quantities serve to prevent the base metal from touching a workpiece even if the tip is weared resulting in the prolongation of tool life.

Title: Solution diluting device, method for adjusting solution concentration and method for forming pattern
Inventor: NAKANO TOSHINORI
IPC: H01L21/027
Filed: 1997-04-22
Abstract: PROBLEM TO BE SOLVED: To maintain the titration accuracy of a first solution at a high level by measuring the concentration of a second solution periodically (wherever desired) to seek an equivalent point in the mixing of the second and a third solution and titrating the first solution using the second solution again, based on the measurement results, when diluting the first solution with pure water. SOLUTION: This solution diluting device titrates (a first titration process) a diluted developer 13a by using a sulfuric acid reagent (a second solution) 15a, then titrates a NaOH solution (a third solution) by using a sulfuric acid reagent 15a before or after the first titration process, when developer 11 for a positive type resist (an alkaline solution; the first solution) is diluted with a high-purity water 12. Further, the device measures (a second titration process) a change in the concentration of the sulfuric acid reagent 15a over time periodically (whenever desired) to seek an equivalent point in the mixing of the sulfuric acid reagent 15a with the NaOH solution (the third solution) 16a. Next, the concentration is measured at a high accuracy level and again the first titration process is carried out with high accuracy.

Title: Method for detecting reduction in thickness of metal wall
Inventor: UMEMOTO TADAHIRO
IPC: G01N3/34
Filed: 1990-04-20
Abstract: PURPOSE:To easily and correctly detect a reduction in thickness of a tube wall or the like from a surface of a metal wall by detecting an inherent vibration and attenuation characteristics at the time of application of a mechanical impact and comparing them with reference values on the metal wall in an initial state. CONSTITUTION:A surface of a metal wall 1 to be inspected is struck by an impact generating jig 3 to apply impact force to the metal wall 1 so that a vibration in an arrow V-V' direction with a fixed point 2 as the center is permitted to take place. The vibration is detected by a vibration detecting element 4 to measure a magnitude of the vibration, the number of vibrations, a change in amplitude with time, etc. Detected data of vibration characteristics on the metal wall 1 is compared with reference values on the metal wall in an initial state which have been prepared so as to determine whether or not a coordinate A in the initial state has been changed or whether or not it has moved toward coordinates B to D. In this case, since there is a change in vibration characteristics depending on a degree of corrosion of the metal wall, determination of the proper number of vibrations and vibration attenuation of the metal wall 1 based on the change in characteristics is possible.

Filed: 1988-04-27
Abstract: PURPOSE:To improve the resonance supercharge effect by allowing a volume chamber to communicate to the intake passage of an engine through a resonance passage and increasing the intake pulsation of the intake passage by resonating a resonance member in the volume chamber by the intake pulsation. CONSTITUTION:During the operation of an engine 1, the intake sucked through an air cleaner 11, common intake passage 7, tank 15, and an intake passage 5 pulsates in the intake passage 5. For the pulsation of the intake, a resonance plate 19 in a volume chamber 17 which communicates through a common passage 16 resonates according to the spring constant of a spring 20. Through the resonance, the intake pulsation is amplified, and the intake is supercharged into the cylinders 2a-2d by the amplified pulsation. Thus, notwithstanding the simple structure, the intake can be supercharged by the resonance of the resonance member in the volume chamber.

Abstract: PROBLEM TO BE SOLVED: To reduce manufacturing cost without causing a reduction of hardness and strength due to thermal influence at the time of welding by applying welding in at least two sections incontinuously on an outer peripheral face of an end part of a tubular shaft. SOLUTION: Arc welding for joining an end part of a tubular shaft 2 with a join end part 6 is applied to two welded sections A, B incontinuously on an outer peripheral face of the end part of the tubular shaft 2, and two sections C, D which are not yet welded are provided between these sections A, B. The sections which are not yet welded C, D are in a scope of 70 deg. to 100 deg., respectively, and correspond to a circular arc part of the join end part 6. Since two sections which are not yet welded C, D are provided in this way, welding to two welded sections A, B can be done by intermittent welding for simple circumference, robot welding can be eliminated, and manufacturing cost can be reduced. Moreover, hardness and strength are increased on the contrary when compared with the case where welding is applied on whole periphery.
