Title: Stroboscopic device
Inventor: ISHIZAKA SATORU
IPC: G03B15/03
Filed: 1988-03-29
Abstract: PURPOSE:To improve light condensing efficiency and light distribution characteristics by making a part of a discharge tube touch an inner part of a reflecting shade and making a tilt angle to the light radiating direction of the reflecting shade on an aperture part side larger than an angle made by the light radiating direction and a tangent which is tangent to the discharge tube and which goes through the end of the reflecting shade. CONSTITUTION:The tilt angle to the light radiating front direction (the Y-axis) of the reflecting shade 5 on the aperture part side (a condensing lens 6 side) is larger than the angle made by the light radiating front direction (the Y-axis) the tangent (b) which is tangent to the discharge tube 4 and goes through the end of the reflecting shade 5. Consequently, a light beam which is from around the center of the electric discharge tube 4 and reflected first time at a part of ¦X¦>1.7 does not have a big angle to the Y-axis after being reflected, and goes towards a viewing angle going through the condensing lens 6. Furthermore, the light beam which goes backward returns on a same route after being reflected, is reflected second time at the part of ¦X¦>1.7 and also condensed on the viewing direction. Thus, the condensing light efficiency and the light distribution characteristics can be improved.

Filed: 1988-03-28
Abstract: PURPOSE:To obtain a high wave transmission force and a high reception sensitivity by connecting a piezoelectric ceramics for wave reception subjected to polarization processing in the spread direction to the piezoelectric ceramics for wave transmission. CONSTITUTION:The electrode 31 of the upper face of the piezoelectric ceramics 11 is connected to the diaphragm 2. The electrode 41 of the lower face of the piezoelectric ceramics 11 is used in common as the upper face electrode of the piezoelectric ceramics 12. When a wave transmission circuit 71 is oscillated, its oscillated output is fed to the piezoelectric ceramics 11 via lead wires 51, 62, and fed also to the piezoelectric ceramics 12 via lead wires 52, 61. Since the piezoelectric ceramics 11, 12 are arranged so that the direction of self- polarization is opposite, the electrode 41 and the lead wire 61 are used in common and the piezoelectric ceramics 11, 12 are energized in parallel, then the vibration of the spread vibration mode is caused in the same phase to the piezoelectric ceramics 11, 12, and since the vibration force is synthesized to knock the diaphragm 2, then a large ultrasonic wave output is generated from the surface of the diaphragm 2.

Abstract: PURPOSE: To prevent the snapping-off of aluminium wiring, by producing Al 2 O 3  on the surface of the aluminium wiring film and thereafter coating an insulating film on the Al 2 O 3  at a temperature lower than the melting point of aluminium.  
     CONSTITUTION: The aluminium wiring film 4 is made on a P-type silicon substrate 1 having a field oxide film 2 and a gate oxide film 3. The Al 2 O 3  5 is produced on the film 4 by O 2  plasma. An Si 3 N 4  layer 6 is then produced on the layer 5 by  plasma reaction. The corrosion and snapping-off of the aluminium is thus prevented. Because the thermal expansion coefficient difference between the aluminium wiring film and the protective insulating film is small, the cracking of the protective film due to heat shock is prevented.

Abstract: PURPOSE:To eliminate a cord from a pen and to improve the operability by arranging plural long magnetic substances each wound with a coil at a prescribed interval in parallel and using the inductance change in each coil so as to detect the position of the pen when the pen approaches. CONSTITUTION:When the pen 20 incorporating a rod magnet is positioned on the magnetic substances 11a-11h, since the angle between the magnetic flux and each magnetic substance in the lengthwise direction is smaller in a magnetic substance closer to the pen, the inductance of the coil of the magnetic substance closest to the pen is minimized. Thus, the inductance of each coil (12a-12h) is converted into a voltage signal by a converting circuit 30 and a signal selection circuit 40, a voltage difference (differential component) among the coils is taken to calculate the coordinate where the difference is zero.

Abstract: PURPOSE:To attain the uniformity of oxygen deficiency concentration by using a composite oxide sintered body material containing at least Ba, Lu and Cu and sintering the material via specifying a thickness from the surface to the center thereof. CONSTITUTION:A powder mixture obtained by mixing each oxide or carbonate of Ba, Lu and Cu is used as raw powder and crushed after preliminary baking. This process is executed at least once or more. And baked body powder obtained therefrom is formed to such shape that a distance from the surface of a product after sintering to the center thereof is 1mm or less, or more preferably 0.5mm or less, and sintered. In this case, if the thickness of a material is small, reaction with the environment of sintering or heat treatment progresses over the whole of the material preferably for the superconducting characteristics thereof. The superconducting material available therefrom becomes an effective superconductor all over. Consequently, a high superconducting critical temperature Tc inherent to the material is embodied and it becomes possible even to increase real superconducting critical current density Jc.

Abstract: PURPOSE:To obtain a noise reduction device of the video camera in which an operation sound (noise) is reduced to attain recording without losing the presence of sound even when a camera optical system such as an image pickup optical system or a finder optical system whose magnification is switched stepwise is in use. CONSTITUTION:A variable amplifier 168 is integrated with a sound processing system for a sound signal detected by a microphone 130.
