Patent JP-S61283870-A (JP)
Title: Speed measuring apparatus
Inventor: SAKATA MASAO
IPC: G01S17/50
Filed: 1985-06-10
Abstract: PURPOSE:To enable accurate measurement, by keeping the quantity of light received of a spatial filter at a proper level regardless of significant changes in the reflectance of an object to be measured and optical conditions of external light or the like hitting it. CONSTITUTION:When the quantity of light received of a light receiving element 2 is large and the output level of a preamplifier 3 is large, the output level of a level detection circuit 12 increases and a quantity of light adjusting circuit 14 acts to decrease the quantity of irradiation light of a projector 5. To the contrary, with a smaller output level of the circuit 12, the circuit 14 acts to increase the quantity of irradiation light of the projector 5. As the quantity of irradiation light of the projector 5 decreases, the brightness of the roard surface lowers to reduce the quantity of light of the element 2. To the contrary, as the quantity of light of the projector 5 increases, the road surface become light to increase the quantity of light of the element 2. In this manner, a feedback control works to increase or decrease the quantity of irradiation light of the projector 5 so that the quantity level of light received of the element 2 will be almost constant. Thus, the speed can be always measured accurately regardless o significant changes in the reflectance of the road surface and the quantity of external light.

Title: Moisture detector
Inventor: SUGII MASAHIRO
IPC: G01N27/22
Filed: 1977-10-19
Abstract: PURPOSE: To make possible detection of high sensitivity and sure operation by making use of the high impedance of CMOSIC at the time of changing the phase of the pulses of a basic frequency by the use of the floating capacity of a moisture sensor and detcting moisture.  
     CONSTITUTION: A delay circuit is formed by the floating capacity of a moisture sensor 1 and a resistance 10, by which the pluses B of a pulse width τ from a pulse generator 9 are delayed τA and are inputted to a 3-input NAND gate 14. On the other hand, the pulses B from the generator 9 are delayed τC like C by a delay circuit of a resistance 12 and a capacitor 13 and are then inputted to the gate 14. When water deposits on the sensor 1, the floating capacity increases and increases to the delay τ'A like the broken lines of the pulses A. Here, if constants are selected like τ>τ'A>τC>τ, then the output of the gate 14 becomes low like the broken lines of the pulses D and the deposition of the moisture may be detected. Since the IC of the gate 14 is of high input impedance, the values of the resistance 10, 12 may be increased and the delay quantity may be expanded despite minute change in the floating capacity, thus the moisture may be surely detected

Title: Disk-shaped optical information recording medium and its production
Inventor: IINO TETSUYA
IPC: G11B7/24
Filed: 1988-05-20
Abstract: PURPOSE:To form good pits over the entire surface of a disk by using a material having a high thermal conductivity as a protective film in the part of the recording information medium where the line speed is low and using the protective film having the low thermal conductivity in the part where the line speed is high. CONSTITUTION:The material having the thermal conductivity higher than the thermal conductiv ity of an outside circumferential part 11 of a substrate 22 formed of polycarbonate or acrylic resin, etc., is used as the protective film 23 of an inside circumferential part 12 on said sub strate. Namely, the protective layer 23 consisting of AlN is deposited on the sound region 12 of the inside circumferential part and the protective layer 23 consisting of SiO2 is formed to the video region 11 of the outside circumferential part by a sputtering method. The heat required for recording is, therefore, easily diffused in the region where the line speed is low so that rapid cooling is attained therein. The recrystallization of the amorphous recording pits is thus prevented. The diffusion of the heat is small and, therefore, the recording with relatively small power is possible in the region where the line speed is high. The pits of the good shapes are thereby obtd. with the optical information recording medium having the region of the high line speed and the region of the low line speed within the same disk is thereby obtd.
