Title: Ultrasonic flaw detection of bending processing part of thin material
Inventor: YASHIMA MINORU
IPC: G01N29/04
Filed: 1982-11-27
Abstract: PURPOSE:To detect the minute defect of the bending processing part of a thin material, by predetermining the frequency and incident angle of a flaw detecting ultrasonic waves. CONSTITUTION:A probe 18 of which the position is freely adjustable is provided to the support rod 16 of the running truck 4 arranged to an ultrasonic flaw detector 19 so as to make an ultrasonic echo max. Ultrasonic waves with frequencies 4-10MHz or 5MHz outputted by the probe 18 are selected so that the incident angle to the bent processing part of a thin molded processed product immersed in an ultrasonic transmission medium such as water is brought to an angle for maximizing a reflected echo in a range of 22+5 deg.. Whereby, ultrasonic waves are well propagated through the processed product 1 having the bending processed part without generating a noise echo to also detect an internal defect in sensitivity almost the same to the detection sensitivity of an external defect and the highly sensitive flaw detection of the minute defect in the bending processed part of a thin material can be performed.

Abstract: PURPOSE:To improve the width accuracy of an electrode finger and to assure the connection of a bonding part by coating the 1st metallic film on a piezoelectric substrate to obtain plural electrodes, coating the 2nd metallic film on those electrodes and deleting the 2nd metallic film excluding the electrode bonding part. CONSTITUTION:A metallic film 12 vapor-deposited with gold, for example, is coated on a piezoelectric substrate 11 of LiNbO3, etc. Then a resist film 13 is coated on the substrate 11 and the film 12 is etched with an aqua regia etching solution after exposure and development. Thus a prescribed electrode is obtained, and the undesired film 13 is deleted. Thus an electrode 14 is produced. Then Al, for example, is vapor-deposited and the 2nd metallic film 15 is coated by a sputtering process, etc. Then a resist film 16 is formed only at the bonding part of the electrode 14. The film 15 is etched with a mixed solution of nitric acid, phosphoric acid, acetic acid, etc. to delete the undesired film 16. Therefore only a bonding part 17 on the electrode 14 increases its thickness for a surface acoustic wave device 18.

Title: Watermark printing method
Inventor: TAKEFUCHI HIDEAKI
IPC: B42D15/10
Filed: 1981-12-23
Abstract: PURPOSE:To obtain easily a paper with a transparent pattern, having processability even in small amounts, by a method in which printing is performed on a paper by using an SAIB solution while heating and then heated further. CONSTITUTION:In priting a paper with an SAIB (sucrose acetate isobutylate)  solution, the solution is printed after being heated to 70 deg.C or higher or the heating is made to the temperature after the printing in such a way as to make the printed portion an open work to a semitransparent state. However, since the SAIB tends to migrate into the paper layer for a long period of time after printed transparently to make the open work foggy with time because it has a high viscosity but is in liquid state at room temperature. To remedy the defect, a liquid solution of 0.5-2pts.wt. resin whose refractive index is similar to that of cellulose and being solid at room temperature, e.g., a cellulosic derivative, a paraffinic polymer, and alkyd resin, an alicyclic saturated hydrocarbon resin, etc., in an organic solvent is used to treat the SAIB portion. In this way, it is preferable to make the watermark printing portion into a semitransparent state.

IPC: A63F7/02
Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To reduce the controlling load on a discharge control circuit. SOLUTION: A game control circuit 36a judges whether there is the change of information for discharge-possible condition, which becomes a discharge- possible condition for the game ball, or not, based on the detection signal sent from an over flow sensor 26 or a fragment sensor for prize ball 39 and so on. And when it judges that there is the change of information for discharge- possible condition, it sends the state change data, which offers the contents of discharge-possible condition after changing, to a discharge control circuit. The discharge control circuit decides whether it is possible to discharge the game ball or not based on the state change data, which is received, and it interlocks the decision of discharge-possible to discharge the game ball.
