Filed: 1992-06-17
Abstract: PURPOSE:To obtain an optical rain gage which can measure the radius of a rain drop and the amount of rainfall with high precision in a short time. CONSTITUTION:When distances of luminescent spots formed by a reflected light and a transmitted refracted light from a rain drop 1, from the center of the rain drop on a photosensor 6, are denoted by r1 and r2, angles of incidence of the reflected light and the transmitted refracted light on the rain drop 1 by theta1 and theta2, the magnification of an imaging optical system 5 by (m) and the radius of the rain drop 1 by R, an arithmetic device 8 determines R by an equation R=(r1+r2)/m.(sintheta1+sintheta2). When a distance between the object- side principal point of the imaging optical system 5 and the rain drop 1 is denoted by H, an angle formed by the optical axis of images of first luminescent spots in a pair and by a reference line by delta1 and an angle formed by the optical axis of images of second luminescent spots in a pair and by the reference line by delta2, the amount DELTAH of deviation of the rain drop 1 from a focal surface is computed from dimensions of these delta1 and delta2 and a corrective value R' of R is determined by an equation R'=RX(H+DELTAH)/H.

IPC: G04G99/00
Filed: 1995-06-23
Abstract: PURPOSE: To provide a solar battery-driven watch capable of increasing the degree of freedom in designing and invariably realizing a stable clocking action. CONSTITUTION: The dial 2A of the watch is formed out of a light collecting plate 7 for sunlight, and four solar batteries 6A are arranged symmetrically to the center of the light collecting plate 7 to face the outer periphery of the light collecting plate 7.

Title: Production of magnetic recording medium
Inventor: KATO YOSHIKATSU
IPC: G11B5/85
Filed: 1988-06-25
Abstract: PURPOSE:To prevent the deterioration of a shape and to improve yield by blowing a gas to the position where a nonmagnetic base parts from a cooling can. CONSTITUTION:The base 1 travels toward a take-up roll 3 from the cooling can 4. A gas pipe 11 is disposed to the position where the nonmagnetic base 1 parts from the can 4 and the gas of a prescribed volume is blown to the rear surface side of the base 1 at this time. The base 1 is, therefore, parted from the can 4 without exerting large tension to the base 1 even if the base is largely electrified. Generation of build-up or the like on the base 1 is prevented in this way and moreover, the actual trouble in case of transferring to the ensuing stage is prevented.

Title: Waveguide type optical switch element
Inventor: SATO YOSHIKAZU
IPC: G02B6/12
Filed: 1987-06-25
Abstract: PURPOSE:To execute the switching of the propagation direction of light by a light signal for control by forming the reflecting layers in waveguides reversibly according to the kinds of light. CONSTITUTION:A photochromic layer 6 is formed on a substrate 1 having a low refractive index and visible light is projected thereon by using a mask having the patterns of the waveguides to increase the refractive index of the patterned parts to the higher refractive index and to form the waveguides 2, 3. A low refractive index layer 8 is then formed by sputtering of quartz glass. A slit 11 is formed by sputtering of metal chromium and patterning of a light reflecting layer 7, by which a light shielding layer 9 is obtd. The light signal 12 for control projects the crossed part of the waveguides through the slit 11 and the layer 8. The refractive index in the light projected part in the waveguides increases and the propagated light progresses rectilinearly if UV rays are used as the signal 12 with the switch element obtd. in such a manner. On the other hand, the refractive index of the light projected part in the waveguides decreases and the reflecting layer 7 is formed so that the propagated light is bent if visible light is used as the signal 12. The layer 7 is, therefore, reversibly formed.

IPC: H04W48/16
Filed: 1995-06-26
Abstract: PURPOSE: To minimize the consumption of a battery in use not by searching detecting electric field strength from a base station through the selection of any of plural amplification factors but by searching it at a prescribed amplification factor when the portable terminal equipment is discriminated to be at the outside of the service area. CONSTITUTION: A discrimination circuit 7 extracts lowest reception level information receptible from a base station so as to discriminate whether or not a demodulated reception level satisfies it and desired data are obtained. When the desired data are not obtained, an amplification factor of an amplifier section 2 is switched. When at first a medium amplifier section 2b is selected, the desired data are not obtained, then a high amplifier section 2a is selected. When the result is NG, a low amplifier section 2c is selected, and when the result is NG, it is discriminated that the information terminal is resident at the outside of the service zone and the result is informed to a notice section. When out of zone is discriminated, a changeover control section 7 uses a switching control signal to select only the high amplifier section 2a and controls the conduction of search.  When the searching exceeds a prescribed time, a longer search interval is used. When reception level and required data are obtained, it is discriminated that the information terminal is resident in the service zone and the result is noticed.
