Title: Laminated type piezoelectric element and its manufacture
Inventor: SAKAIDA ATSUO
IPC: B41J2/045
Filed: 1995-01-12
Abstract: PURPOSE: To provide a laminated type piezoelectric element used for an ink jet type printing head which is high in yield and reliability and low in manufacturing cost, and its manufacture. CONSTITUTION: A structure wherein a piezoelectric ceramic layer and an inner electrode layer are alternately laminated is provided. By a narrow long hole part 52 opened in its laminated direction, at least its central part is divided into a plurality of actuator parts 46. By impressing voltage selectively to an electrode to each actuator part 46, a required actuator 46 can be independently driven. Further, the actuator part 46 can be driven at a low voltage. Furthermore, since a slit provided to a laminated piezoelectric element 38 is a long narrow hole part 52, and each actuator part 46 is held by a piezoelectric inactive part 48 at its end parts, it is difficult to be broken in manufacture or in driving even though its width is narrow.

Title: Air conditioner
Inventor: NISHIKAWA OSAMU
IPC: F24F1/02
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To reduce a load of an air conditioning operation during a cooling operation and during a heating operation by a method wherein a signal for reducing a degree of opening of surrounding atmosphere feeding port is outputted to a means for adjusting a degree of opening of air feeding port in the case that an air speed of surrounding air entering through the surrounding air feeding port is more than a predetermined value. SOLUTION: When a surrounding air feeding port 11 is opened to take the surrounding air, the surrounding air strikes against an air receiver 14 arranged at the surrounding air feeding port 11, resulting in that the air receiver 14 is oscillated toward an inner side at an angle corresponding to an air speed of the surrounding air. Then, in the case that the oscillation angle is more than a predetermined value, a switch is changed over from OFF state to ON state, a controller 6 controls the means 5 for adjusting a degree of opening of the air feeding port in such a way that a degree of opening of the surrounding air feeding port 11 is reduced in response to the changed- over state. With such an arrangement as above, a degree of opening of the surrounding air feeding port 11 is reduced. Namely, a surrounding air feeding amount per unit time in the case that an air speed of the surrounding air is more than the predetermined value and one in the case that an air speed of the surrounding air is less than the predetermined value are approximately the same to each other.

Abstract: PURPOSE:To obtain a hole structure with a less occupied area in a semiconductor device by a method wherein the hole structure is made to have a contact hole, which exists in an active region having a reverse conductive type to that of the semiconductor substrate and has a depth deep enough to reach the substrate, and a metal wiring layer formed in such a way as to cover the upper part and side surface of the hole. CONSTITUTION:A contact hole 17 is shaped like a hole bored in a substrate 1 in a depth of about 1mum at this part, where the hole 17 itself is existing, for taking the potential of conductive regions 4' forming a source and the potential of the semiconductor substrate 1. An aluminum wiring layer is formed on the sidewall of the hole 17 and the regions 4' and the substrate 1 are mutually connected. However, at this time, as there is a possibility that a metal wiring 9 may be brought into a state of Schottky contact with the substrate 1 in some cases by the concentration of the P type substrate 1, it is better that a high-concentration region of P type impurities as indicated by A in the diagram has been previously formed by an ion-implantation technique, etc. As a result, the wiring 9 can be done with enough area to cover at least the hole 17 and any restriction due to the intervals between the wiring 9 and the neighboring wirings can be completely eliminated.

Filed: 1981-01-14
Abstract: PURPOSE: To remove a runner and a gate by a mechanical means without manual operation or press working by a method wherein the gate and runner are separated from a lead frame by twisting the frame during the feed of the frame after insert molding.  
     CONSTITUTION: The frame 1 delivered from a reel at the right is subjected to the insert molding 7, and then it is fed to a secondary working head 8 while maintaining a continuous condition. During the feed, the frame is twisted 9. Under the twisting of the frame along the feed direction, the frame consisting of a metallic body flexibly follows up to the inclination of the twist, but the molded runner and gate cannot easily follow up to the twist because of the stiffness, so that the tunner-gate body is easily separated from the frame. The runner or gate part is provided with legs 10, 10' for clamping a crosspiece 5 of the frame, thereby facilitating the separation.

Title: Optical disk
Inventor: OKAMURO AKIO
IPC: G11B7/2407
Filed: 1992-01-14
Abstract: PURPOSE:To provide an optical disk wherein in recording, erasing of information already recorded on the adjacent track or writing of wrong information is prevented. CONSTITUTION:The optical disk of this invention is formed by laminating on a substrate 1 a recording layer 3 and a thermal diffusion layer 6 of a non- magnetic metallic film, e.g. a Cu film, Al film or Ag film, and has concentric or spiral tracks or intertrack areas. The thermal diffusion layer 6 is not provided between the tracks or porvided more thinly than the tracks. Since the thermal diffusion layer 6 exists in the tracks, the power margin for recording or reading, particularly the maximum reading power increases. Further, since the thermal diffusion layer 6 is not provided between the tracks or provided more thinly than the tracks, heat conduction to the adjacent tracks is reduced, and the data on the adjacent tracks is never destroyed even if a fairly large power is used for recording or there is off tracking to a practical extent.
