Title: Semiconductor laser element
Inventor: KAWADA HATSUMI
IPC: H01S5/00
Filed: 1984-10-22
Abstract: PURPOSE:To prevent a formation at two points of light-emitting spots, and to obtain a stable transverse mode by forming a striped groove to a V shape. CONSTITUTION:A striped groove, which reaches the inside of a second clad layer 4 from the surface of a current constriction layer 5 and is formed, is shaped to a V form. Consequently, an oscillating threshold can be lowered, and not only characteristics fit for an optical-disk light source such as the improvement of the circle of beams and the reduction of astigmatism are obtained but also a stable fundamental transverse mode is acquired because of the V-shaped striped groove. That is, there is only one position of a corner section where the film thickness of a high refractive-index layer 6 is thickened on the growth of the layer 6 in the V-shaped striped groove. As a result, beams are wave-guided only at one position of the corner section. Accordingly, beams are not wave-guided at two positions as seen in conventional devices and do not emit light, thus acquiring laser beams at the stable transverse mode.

Title: Laminated piezoelectric ceramic actuator element
Inventor: MURATA KOJI
IPC: H01L41/083
Filed: 1997-08-19
Abstract: PROBLEM TO BE SOLVED: To reduce a shearing stress caused by a stress concentration when an element is driven and to improve a repeated drive life, by forming the corners of inner electrode layers such that each of them has a curvature of more than a certain multiple to the shorter side of the rectangular inner electrode layer, on the assumption that the corner of the inner electrode layer is a right angle. SOLUTION: A laminated piezoelectric element has inner electrode layers 1a, 1b interposed between piezoelectric layers 5, and outer electrodes which are opposed to each other and electrically connected to the inner electrode layers 1a, 1b opposite to each other. Since the inner electrode layers are smaller than the piezoelectric layers 5, they are insulated from the outside except for the outer electrodes. Each of all the inner electrode layers has a curvature of more than 0.066 to the shorter side of the rectangular inner electrode layer, on the assumption that the corner 6 of the inner electrode layer is a right angle, which increases the total length of a boundary of an effective drive layer and an ineffective drive layer near the corner. This relieves a stress concentration in the direction of thickness of a corner 6 where stress is concentrated when the element is driven.

Thus, since the releasing lever 7 is housed in the case, the clamp is never released by mistake during the handling time, and the disk is never unsteady either.

Title: Treatment of lead-containing copper alloy for suppressing leaching of lead and implement for water service made of lead-containing copper alloy
Inventor: KAWAMOTO TOSHIYUKI
IPC: C23F1/44
Filed: 1999-08-06
Abstract: PROBLEM TO BE SOLVED: To remove lead in the surface of a lead-containing copper alloy and to effectively suppress the leaching of lead in the use of an implement by immersing the copper alloy in a fluoride added chromic acid solution after immersion in an alkali etching solution. SOLUTION: A lead-containing copper alloy is immersed in a fluoride added chromic acid solution. This chromic acid solution has high oxidizing power and dissolves lead while dissolving the entire surface of the copper alloy. When the copper alloy is immersed in an alkali etching solution containing an added oxidizing agent before the immersion in the chromic acid solution, a chemical reaction in which lead in the surface of the copper alloy is directly converted into a water-soluble alkali metallic plumbite by contact with the alkali solution and a chemical reaction in which the lead is converted into lead oxide once by the oxidizing agent and this lead oxide is converted into the alkali metallic plumbite, proceed. Since the latter reaction is more rapid than the former reaction, the dissolution of lead is accelerated.  A chromate coating is preferably formed after the lead in the surface of the copper alloy is dissolved and removed.
