Title: Waterproofing method for printed board
Inventor: MATSUO SHIGERU
IPC: H05K3/28
Filed: 1988-07-19
Abstract: PURPOSE:To absorb the thermal expansion of fillers by a cavity section, and to prevent the cracking of solder by forming a hole section to a printed board in the lower section of a large-sized part such as a transformer while shaping a projecting section penetrating the hole section into an injection die and forming the cavity section to the fillers. CONSTITUTION:A fixed quantity of liquefied uncured fillers 2 to which a liquid reaction curing type urethane group substance is mixed are injected into an injection die 3 composed of a synthetic resin, etc. A printed board 3 to which a switch 4, an LED 5 and a transformer 6 as a large-sized part are mounted is arranged so as to be buried into the liquefied uncured fillers 2. Projecting sections 1a, 1b formed to the injection die 1 are penetrated into holes 3a, 3b shaped to the printed board 3 in the lower section of the transformer 6, thus preventing the inflow of fillers 2 to the lower section of the transformer 6. The printed board 3 is pushed from an upper section by a pressing die 7, and heated and cured. Cavity sections 2a, 2b shaped to the layer of the fillers 2 are positioned at the lower sections of the transformer 6, thus absorbing stress due to the thermal expansion of the fillers 2, then obviating the cracking of solder near the cavity sections.

Title: Hand piece structure for dental use
Inventor: HIGUCHI TAKEHIRO
IPC: A61C1/08
Filed: 1999-06-25
Abstract: PROBLEM TO BE SOLVED: To extend the life of light source, and to surely avoid the situation of failure of electric supply to the light source. SOLUTION: This hand piece is provided with a light (source) 21 fixed to a connector 25 free to attach and detach at a second tip 2b of a connecting portion 2. The irradiating portion 20a of an optical fiber 20 arranged in the interior of the connecting portion 2 is formed into an annular structure. This constitution reduces thermal load since the lamp 21 is not heated by steam and eliminates tribology of contact point, and also leads to an extended life and surely avoids the situation of electric supply failure to the lamp 21. In addition, when a grip sleeve 3 is rotated during dental treatment, the light irradiated from the lamp 21 is surely transmitted via the optical fiber 20 to an optical fiber 5 provided in the interior of the grip sleeve 3.

Title: Velocity measuring apparatus for surface acoustic wave
Inventor: NISHIMORI HIROYUKI
IPC: G01N29/00
Filed: 1992-07-07
Abstract: PURPOSE:To measure simply the velocity of a surface acoustic wave of a solid by setting first and second angle probes for reception at different distances and by determining a time difference between reception signals of the two. CONSTITUTION:A transducer 3 for reception of an angle probe 21 for reception is fitted to a delay material 4 and a transducer 5 for reception of an angle probe 22 for reception to a delay material 6 respectively and they are integrated by a housing 7, at different distances from distances L1 and L2 between points of incidence. Based on an electric signal sent from a pulser 10 of an ultrasonic flaw detector 9, an ultrasonic wave is excited by a transducer 1 for transmission and propagated through a delay material 2 and a surface acoustic wave is propagated to the surface of a sample 8. The wave is propagated through the delay material 4 being off at the distance L1 and converted into an electric signal by the transducer 5 for reception, while it is propagated through the delay material 6 being off at the distance L2 and converted into an electric signal by the transducer 5 for reception. These signals are taken in an addition circuit 11, amplified by a receiver and processing circuit 12 and displayed by a monitor 13. Since a distance L between the points at which the surface acoustic wave is propagated through the sample 8 is known and fixed, the velocity Cr of the surface acoustic wave propagated between the points is determined by measuring a time tL of propagation and by using an equation Cr= L/tL.

Abstract: PURPOSE:To accurately determine the quantity of eccentricity by a method wherein a value most frequently detected in diameter distribution is presumed to be a wafer diameter before an accurate wafer diameter is determined, a four-point position detection free of noise, etc., is accomplished, and the quantity of eccentricity is determined using the result of the four-point position detection. CONSTITUTION:Outer circumference position data along the entire wafer circumference are determined by a wafer outer circumference position data detecting means, distances rhofrom the center of rotation of a theta-stage 2 to the wafer edge is detected at every point, a distance rho1 involving a point (i) and a distance rho1+180 deg. involving a point i+180 deg. which is 180 deg. degrees apart from said point (i) are summed up, for the approximation of a wafer diameter r1 involving said point (i). The same is repeatedly accomplished to cover half the wafer circumference for the preparation of a wafer diameter frequency distribution, wherein the most frequently observed value is presumed to be a diameter (r). Distances from the center of rotation of the theta-stage 2 to four points, free of noise and 90 deg. apart from each other, are measured for the determination of the quantity of eccentricity from the center of rotation. When four points are not available, three points separated by 90 deg. may be used to determine the quantity of eccentricity, when the most frequently appearing value in the frequency distribution is determined to be the quantity of eccentricity.

Filed: 1986-07-31
Abstract: PURPOSE:To get along even when the memory capacity of a buffer memory is small by providing a means to execute the tab action based upon a character code and the information in the second memory means in succession to a tab executing command code issued from an input means. CONSTITUTION:Especially, in a character processing device to execute a character processing work of an input editing, etc., of a character column on a displaying picture, a tab setting position on a displaying means is stored into a memory separate from the memory to store a character code, and based upon the memory information, a tab executing command code and the character code in succession to the tab executing command code, a tab action is executed. Thus, without storing a tab code onto the memory simultaneously with the tab execution, the improvement of the using efficiency is obtained by the buffer memory with the small unused part and a comparatively small capacity, and the input editing processing of a new character at any position on the displaying picture can be easily executed.

Inventor: TAKAHASHI MASAHIRO
IPC: B21D22/20
Filed: 1998-06-26
Abstract: PROBLEM TO BE SOLVED: To stably secure the flattened shape of an upper flat sheet surface by giving stress in parallel with an upper flat sheet surface toward the opposite side direction of the round corner part with a forming die and/or a wall part and specifying the max. dislocated height of the upper flat sheet surface. SOLUTION: The stainless steel sheet-made kitchen upper flat sheet part 20 and a sink part 18, are joined. At this time, the positions 30a, 30b having defective shape, are generated on the upper flat sheet surface 16. The direction giving the stress for correcting the shape, is directed to the surface of the upper flat sheet part 20, i.e., in parallel with the upper flat sheet surface 16 and toward the opposite side direction from the outer surface of the sink part 18. In the case of correcting the positions 300 having defective shape, the positions generating the tension stress in the parallel direction with the upper flat sheet surface 16 to the upper flat sheet part 20 are inevitably limited to the round corner part 32 with the die and/or the wall part 34 of the deep drawing part vertically formed to the upper flat sheet surface.  In order to correct the defective shape, the stress is given in parallel with the upper flat sheet surface 16 toward the opposite side direction and plastic deformation is executed to set the max. dislocated height of the upper flat sheet surface 16 to <=1 mm.
