Title: Linear array type ultrasonic probe
Inventor: KANEKO NAGAO
IPC: H04R17/00
Filed: 1983-09-05
Abstract: PURPOSE:To eliminate troublesome position-matching of a strip-shape electrodes during lamination and to attain inevitably the improvement of productivity and high efficiency, by providing the strip-shape electrode only on one of opposing surfaces of a high polymer piezoelectric bodies which are laminated by mutually opposing their polarization direction axes. CONSTITUTION:Silver is vapor-deposited for about 1mu thickness on both sides of a linearly-drawn PVF2 film about 55mu thickness. Silver is polarized, for instance, under an electric field of 6kV at a temperature of 100 deg.C for an hour, and is rapidly cooled down to the room temperature to create a PVF2 piezoelectric film 1. So as to make parallel with a polarization direction of the surface of this piezoelectric film 1, a strip electrode 2 is, for instance, element-formed 64 by etching, so that its unit element width attains to about 0.9mm. and its unit element interval about 0.1mm.. In this case, the surface on which the strip-shape electrode 2 is formed and an electrode surface 3 on the opposite side are formed into a common electrode surface which is patterned when necessary. Then, the piezoelectric film 1 is folded into two, so that the strip electrode 2 is located between the piezoelectric films, which are opposing to each other, bonded by an adhesive and laminated.

Title: Lens barrel
Inventor: SATO KAZUHIRO
IPC: G02B7/02
Filed: 1988-06-28
Abstract: PURPOSE:To decrease the number of components of a stop mechanism and to reduce the quantity of projection in a radial direction as much as possible by supporting the fulcrum of rotation of stop blades inside a connection part and engaging an operation shaft with the cam of an arrow wheel 7 outside the connection part. CONSTITUTION:A cam groove 7a moves by the clockwise rotation of the arrow wheel 7 and then the operation shaft 8a moves in the direction of an optical axis O to rotate a blade 8 clockwise around the support shaft 8b, thereby performing stopping-down operation. Then even when the position of the operation shaft 8a is put as close to the connection part 10 as possible to reduce the distance L2 from the optical axis O to the operation shaft 8a, the operation shaft 8a moves away from the connection part 10 as the blade 8 rotates clockwise around the support shaft 8b by arranging the support shaft 8b inside the connection part 10, so the blade 8 does not collide against the connection part 10. The distance L2 is shortened as much as possible to decrease the external diameter of the blade 8 and the number of components of the stop mechanism is decreased.

Title: Interface converter of information process system
Inventor: MUNAKATA AKIO
IPC: H04L29/10
Filed: 1980-11-21
Abstract: PURPOSE:To obtain an interface converter which is provided between an upper general-purpose device and a lower device and avoid an immediate disuse of a connection to the upper general-purpose device with the interface freezing that is caused when the processing operation of the lower device becomes faulty. CONSTITUTION:In case a lower device has a fault such as a delay of the information process, to freeze the interface, an interface converter detects this interface freezing and produces the false informatin. Thus it is impossible for an upper device to decide the interface freezing, and accordingly the upper device never disuses the connection to eliminate a complicated operation of an operator which is due to the activation of the circuit. Furthermore just the queuing is required with the same interface conditins as before without changing the physical interface conditions regardless of the freezing state. As a result, no reduction is caused to the working efficiency of the information process system.

Abstract: PROBLEM TO BE SOLVED: To automatically check component interference. SOLUTION: A graphic data generating tool 11 generates and stores assembly drawing data in a figure data base 15. A group setting tool 12 puts a plane view, a front view, and a side view of one component in one group, defines a component number and a component name, and stores them in the figure data base 15. A quadrant dividing tool 13 defines section lines for sectioning quadrants and displays them on a display. A component interference checking tool 14 recognizes the respective elements of the assembly drawing data in the figure data base 15 by the components and quadrants according to the group setting, decides whether or not there is an intersection between the elements of the two components, and calculates whether or not there is the intersection and the number of intersections.  Then they are compared with interference patterns registered in a pattern data base 16 to find a corresponding interference pattern, and it is judged whether or not there is interference; if there is the interference, it is displayed on the display.
