Title: Ultrasonic probe and its production
Inventor: WAKABAYASHI KATSUHIRO
IPC: H04R1/32
Filed: 1993-08-20
Abstract: PURPOSE:To provide an ultrasonic probe using a piezoelectric element capable of performing polarization without using a polarizing electrode and not generating the destruction of piezoelectric ceramics even by the application of voltage by constituting the piezoelectric element so that spontaneous polarization changes gradually from the center part of the piezoelectric element to the outer peripheral part thereof. CONSTITUTION:A piezoelectric element 1 is constituted by forming full-face electrodes 2, 3 on both surfaces of disc-shaped piezoelectric ceramics 15. The piezoelectric ceramics 15 is subjected to polarization treatment before the full-face electrodes 2, 3 are formed and, by this treatment, spontaneous polarization changes gradually from the center part of the piezoelectric element to the outer peripheral part thereof. The polarization treatment is performed by a method wherein a pair of electrodes 16 composed of conductive rubber and almost same in diameter are closely brought into contact with both surfaces of the piezoelectric ceramics 15 to hold the ceramics and DC voltage is applied across both electrodes to perform first polarization and, subsequently, the part excepting the outer peripheral part of the piezoelectric ceramics 15 is held between the electrodes 16 composed of conductive rubber reduced in diameter to perform second polarization and the electrodes 16 composed of conductive rubber further reduced in diameter are used to perform third polarization.

Title: Electrophotographic device for which amorphous silicon photosensitive body is used
Inventor: YAMAZAKI MUTSUKI
IPC: G03G5/08
Filed: 1986-09-29
Abstract: PURPOSE:To prevent the flow of an image while humidity is high by providing a latent image forming means which forms an electrostatic latent image on a photosensitive body, a developing means for obtaining the visible image by development and a metallic blade which makes sliding contact with the surface of the photosensitive body after transfer, is held grounded and removes the developer on the surface of the photosensitive body. CONSTITUTION:The photosensitive body 2 is uniformly charged by an electric charger 3 and is formed with the electrostatic latent image by an exposing device 4, then the electrostatic latent image is developed and visualized by a developing device 5 while the base body 1 of the photosensitive body rotates in an arrow direction. This visible image is transferred by a transfer device 6 onto transfer paper 7. The image is fixed by melting after the transfer paper is released. the residual developer on the surface of the photosensitive body is scraped off by a blade 8. The blade 8 is metallic and is grounded by which the charge on the surface of the body 2 is dropped to the ground and the residual image on the surface of the photosensitive body is erased. The surface of the photosensitive body is uniformly charged by the charger 3 and such copying operations are repeated. Since photoirradiation for the purpose of destaticization is not executed, the generation of carriers in the photosensitive body at the time of destaticization is prevented. The flow of the image during the use in highly moist environment is thereby obviated and the excellent image is obtd.

IPC: G05D1/02
Filed: 1987-09-14
Abstract: PURPOSE:To prevent the collision between unmanned carriers without stopping unnecessarily either one of both carriers when they are operated opposite to each other by deciding a collision avoiding route for each of those carriers driven opposite to each other and performing the control so that the carriers are driven on each decided route. CONSTITUTION:The driving speed of one of two unmanned carriers driven opposite to each other is detected by a driving speed detecting means 4. Then the relative distance and relative speed are detected by the relative distance/ speed detecting means 1-3 to the opposite carrier. At the same time, the carrying priority is informed from the opposite carrier by a carrying priority informing means 5. Then a collision avoiding route is decided by an avoiding route deciding means 6 based on said relative distance and speed, the driving speed and the carrying priority. In such a way, it is possible to prevent the collision between the carriers without stopping unnecessarily either one of both carriers in case plural carriers are driven opposite to each other on a single track.
