Title: Magnetic recorder, magnetic recording medium and its production
Inventor: KAIZU ISATAKE
IPC: G11B5/73
Filed: 1995-06-27
Abstract: PURPOSE: To reduce noise in the case of recording and reproduction by heating a magnetic recording layer to >=400 deg.C during or after the formation of the layer and forming plural isolated particles of a ferromagnetic material having <=50nm average particle diameter by the heating. CONSTITUTION: When a magnetic recording layer 25 of an alloy of a ferromagnetic material 22 with a nonmagnetic material 23 is formed in 10nm thickness on a head resistant nonmagnetic substrate 21, the intrasurface distribution of the ferromagnetic material 22 in the recording layer 25 is made uniform. When Co is used as the ferromagnetic material 22 and Ag is used as the nonmagnetic material 23, the grain diameter of Co is as small as several nm or below and the recording layer 25 has low coercive force. The substrate 21 with the formed recording layer 25 is heated at 500 deg.C for 10min in a heating furnace. By this heating, Ag and Co are separately deposited in the recording layer 25, the diameter of Co is regulated to <=50nm and particles of Co are separately coated with Ag.  A protective film 26 of carbon is then formed in 10nm thickness on the recording layer 25 to obtain the objective magnetic recording medium ensuring low noise.

Title: Timepiece
Inventor: ITO KENZO
IPC: G04G9/00
Filed: 1993-06-30
Abstract: PURPOSE:To allow the display of time at an arbitrary time unit exceeding 24 hours by displaying a time unit added with 24 as a current time when a measured time is later than 0 a.m. but earlier than an upper limit set time along with the date of previous day. CONSTITUTION:A CPU 3 performs time measuring processing based on a timing signal generated from a frequency division/timing circuit 2 and displays 7 an updated time. When the display mode is 12/24 hours, a key K1 at a key input section 8 is turned to switch the display mode from 12/24 hours to 30 hours. If the current time is later than 0 a.m. but earlier than 6 a.m., the numeric value of time unit representative of current time in a time register is added with 24 and displayed 7 as 25 o'clock 35min, for example. At the same time, 1 is subtracted from the current date in a date register and displayed 7. This constitution eliminates the need of time conversion thus preventing error in the observed time caused by conversion miss.

Filed: 1997-06-18
Abstract: PROBLEM TO BE SOLVED: To detect the distortion of subsoil linearly over a long range with a system at a lower cost, by burying a sensor cable over a required length. SOLUTION: In a sensor cable with a required length, a center of rigidity strand 2 and two optical fiber-contained protective tube 3 are arranged. Spacers 4 are interposed along the length of the cable at an interval of several m to 10 m or so and a cover material 5 is arranged between the spacers 4. A excavated hole is made in the subsoil between manholes and the sensor cable is drawn to be buried. The two ends of the center of rigidity strand 2 are fixed on a connection box in the manholes. An optical fiber 24 is connected to a distortion measuring device via the connection box.  If detected light from the distortion measuring device is sent out to the optical fiber 24, a distortion in elongation is developed in the optical fiber 24 when abnormality, for example, a sign of land sliding is caused at a part of the subsoil and hence, scattering phenomenon of the detected light is caused at this point. Brillouin scattered light is received to detect the size of the distortion from a shift value of a wavelength, thereby learning the point where the distortion is developed from the arrival time thereof.

Abstract: PURPOSE:To achieve deflection and condensation simultaneously with simple constitution by forming a thin film, varying a propagation speed gradually, on an elastic wave propagation path. CONSTITUTION:On a piezoelectric substrate 1 of, for example, lithium niobate, an optical waveguide 8 is formed by deflecting tithanium and on the surface, interdigital electrodes 2 are formed; and, for example, an SiO2 film 12 is formed, varying in film thickness gradually, on a propagation path so that the propagation speed of a surface acoustic wave decreases gradually as the surface wave travels. Even if an energized electric signal has a contant frequency, the wavelength decreases gradually at the part of the film 12 thus forming a grating which has a gradually varying frequency. Incident light from a part 5-a has a greater angle of diffraction than that of incident light from a part 5-b, and diffracted light beams 13 and 14 are not in parallel; the light 13 is condensed and the light is diffused. Thus, the propagation speed of the surface wave is varied to achieve deffection and condensation at a time.
