Title: Laser working device
Inventor: FUJIMORI YASUTOMO
IPC: B23K26/02
Filed: 1984-09-27
Abstract: PURPOSE:To execute irradiation of a laser beam to only the inside of a working area by constituting a titled device so that an opening of an aperture is provided in accordance with a critical point interval in the working area, and a start signal is outputted at the time point when a reflected light which has passed through all the openings has been detected. CONSTITUTION:In case when a condensing spot 12a is being irradiated on critical points 14a, 14b of a member 2, each spot image 24a, 24b of reflected light passes through an opening 18 and it is made incident on a photodetector 19. Also, in case when the member 2 has been dislocated, focusing beams 12, 13 irradiate a position of points 25a, 25b on the surface of a bottom plate 1. In this case, an interval of the points 25a, 25b is narrower than that of the critical points 14a, 14b, therefore, spot images 26a, 26b by reflected lights from the points 25a, 25b are formed between openings 18. On the other hand, in case when the member 2 has been dislocated to the right side, the irradiated spot is reflected and becomes a spot image 27a passing through the opening 18, and the spot irradiated on the bottom plate 1 due to the dislocation is reflected and becomes a spot image 27b formed on an aperture 17, and does not pass through the opening 18.

Title: Observing device for transparent body
Inventor: ISAKA KINICHI
IPC: G01N21/21
Filed: 1981-12-11
Abstract: PURPOSE:To recognize a transparent electrode pattern easily and visually from the intensity of the reflection of a polarized component parallel to a substrate by reflecting only the polarized component so that the tangent of its angle of incidence is the index of reflection of the substrate. CONSTITUTION:Light from a light source 1 is collimated through a lens 2. A polarizing plate 3 extracts only a polarized component parallel to a substrate 4. Then, it is made incident with tantheta=n (n: index of refraction of the substrate) and its reflected light is observed through an objective 5. Therefore, a different index of refraction from the substrate is obtained in the background where incidence is caused at a Brewster angle, so it is observed through the objective that there is the part where incidence is caused at a different angle from the Brewster angle, thus performing high-contrast observation.

Title: Piezoelectric vibrator
Inventor: OKAZAKI MASAKI
IPC: H03H9/19
Filed: 1988-08-11
Abstract: PURPOSE:To reduce the width and to miniaturize by making coincident the plate surface direction with the lengthwise direction of a metallic base with the lead wire of a piezoelectric vibrator composed by connecting electrically and mechanically a piezoelectric piece to a lead wire to penetrate the insulator part of the metallic base as a flat plate shape. CONSTITUTION:A crystal vibrator holds a crystal piece 1 on a metallic base 2 and a base main body 6 is approximately rectangular and has an oblong hole 11 at both edge sides in a length-wise direction. The oblong hole 11 is made coincident with the lengthwise direction of the metallic base 2. A sealed terminal 7 makes a lead wire 12 into a flat plate material and is formed by being covered with an insulator 13 at the circumference. Consequently, even when the width (c) is made smaller, the cross section is enlarged, the connection strength can be maintained, accordingly, the width (b) of the insulator 13 is made smaller, the matching area is enlarged and the matching strength with the base main body 6 is not damaged. Thus, the width of the metallic base 2 is reduced and the crystal vibrator can be miniaturized.

Abstract: PURPOSE:To produce a dense electrode having superior adhesion and a long service life and producing little internal strain during electrodeposition by successively forming an underlayer contg. Pt and Pd oxide, an intermediate layer of alpha-PbO2 and a coating layer of beta-PbO2 on a substrate of a corrosion resistant metal. CONSTITUTION:A plate, a porous plate, a bar or the like of a corrosion resistant metal such as Ti, Zr, Nb, Ta or an alloy thereof is used as a substrate. The surface of the substrate is preferably made uneven so as to increase the surface area. An underlayer contg. Pt and/or Pd oxide is formed on the surface of the substrate so as to protect the substrate and to improve the adhesion to an intermediate layer. In the underlayer, Pt is usually metallic but Pd is required to be oxide because metallic Pd has inferior corrosion resistance. An intermediate layer of alpha-PbO2 acting chiefly as a binder is the formed on the underlayer and a coating layer of beta-PbO2 is further formed on the intermediate layer. The coating layer has a great affinity for the intermediate layer.

Abstract: PROBLEM TO BE SOLVED: To impart a detergent dissolving function being suitable for the kind of laundry or the kind of a detergent, to a washing machine. SOLUTION: For a washing course in which a powdery detergent or a normal detergent which is hard to dissolve is used, a detergent dissolving is executed in a washing tank by a strong water current. In the meantime, for a dry course to wash dry cleaning designated clothes, in which a detergent itself is comparatively easy to dissolve with water but the luandry is easy to be damaged, after inputting the detergent (S40), the detergent is dissolved by a weak water current (S44), and then, the luandry is input (S45), and a washing is performed (S49). Therefore, even if the laundry is accidentally input in a washing tank while the detergent is being dissolved, clothes are not damaged because the water current is weak.
