Title: Ultrasonic solid-state delay element
Inventor: YAMANAKA KAZUO
IPC: H03H9/36
Filed: 1984-04-25
Abstract: PURPOSE:To reduce the working distortion and improve the aging characteristic of an ultrasonic solid-state delay element, by using glass as the delaying medium and using a natural surface as the delaying medium surface which is parallel with the propagating direction of ultrasonic waves. CONSTITUTION:A delaying medium 5 is a glass plate pulled up by a floating system and the thickness of the glass plate is previously set so that it can be used for an ultrasonic solid-state delay element 6. The glass plate is cut to the size of a prescribed delay element 6 as shown by the alternate long and short dash line. Firstly, side faces are cut along longitudinal lines and, secondly, cut- off faces are cut at once. The side face which is used as the reflecting surface of the delay element 6 is cut, but flat surfaces 10 and 10' which are parallel with the propagating direction of ultrasonic waves are not prepared through any mechanical working process and natural surfaces formed when the glass plate is prepared by pulling up are used as the surfaces 10 and 10'. Then input-output convertors 8 and 9 are glued to the cut-off faces 7. When the delay element 6 is manufactured in such a way, the working distortion can be reduced and deterioration of its aging characteristic can be prevented.

Title: Active sonar device
Inventor: OKABASHI NOBUAKI
IPC: G01S15/66
Filed: 1990-03-30
Abstract: PURPOSE:To prevent plural sonars from interfering with each other and to enable target detection by varying a transmission frequency and a reception frequency band corresponding to the travel azimuth of the active sonar device. CONSTITUTION:The travel direction of the active sonar device (AS) is detected by an azimuth detecting circuit 8, whose output is sent as an azimuth signal 9 to a sent signal generator 2 and a band-pass filter 5. Then the generator 2 varies the frequency of an electric signal for transmission with the signal 9 and the filter 5 varies the passing frequency band of an electric signal for reception. At this time, a sound wave of the transmission frequency is sent 1 into water and the reception frequency band is matched with the underwater sound signal frequency band wherein a receiver 6 receives the sound wave. Consequently, when, for example, two underwater sailing bodies 11 and 12 send directional beams 11' and 12' of transmission frequencies f2 and f4 while sailing opposite each other, the reception bands of the AS are different and their received sound waves are outside the reception parts of the opposite waves and, therefore, never interfere with each other, so that the target is detected.

Title: Floppy disk device
Inventor: SAITO KAZUNORI
IPC: G11B33/02
Filed: 1985-04-19
Abstract: PURPOSE:To avoid the deformation of a chassis by absorbing the internal stress of the chassis at a connecting part between chassis of different materials by producing the bending moment within a long screw set on a chassis bent into a projected form. CONSTITUTION:When ambient temperature varies, the internal stress is produced at chassis 28 and 29 of different materials due to the difference of the linear expansion coefficients since both chassis are connected via a long screw. The length of the screw 30 is very large compared with its diameter and therefore the bending deformation is produced in a comparatively easy way. Then the internal stress produced in the chassis 28 and 29 is consumed by the bending moment produced within the screw 30. Thus an aluminum dicast chassis 28 and a sheet metal chassis 29 are put together via the screw 30 at an area where the chassis 29 is bent into a projected form. Then the internal stress produced in both chassis 28 and 29 can be reduced by the bending deformation of the screw 30.

Abstract: PROBLEM TO BE SOLVED: To provide an electrically controlled mechanical timepiece the duration of which can be prolonged, by reducing the occurrence of eddy current losses caused by leakage magnetic fluxes even when a main plate containing a magnetic material portion is used. SOLUTION: The distance L1 between a main plate 3 made of a magnetic material and a rotor magnet 13a is adjusted to >=1.5 times of the gap G1 between the rotor magnet 13a and a stator 21.
