Title: Rotating synchronization signal detecting circuit
Inventor: HAGIWARA AKIHITO
IPC: G11B19/28
Filed: 1985-04-10
Abstract: PURPOSE:To detect a rotating synchronizing signal which stably rises sharply at the same circuit without conforming to the difference of the reflecting ratio of the disk-shaped recording carrier by providing a differentiator, a peak holding circuit, a bottom holding circuit, a comparator and a gate output generating circuit. CONSTITUTION:By differentiating the output electric signal obtained from a photodetecting element 1, the signal to show correctly the edge of a rotating synchronizing mark 14 can be obtained. By providing the peak holding circuit 3, the bottom holding circuit 4 and the comparator 6, the threshold value of the comparator 6 is also changed accompanying the height of the signal level and therefore even when the reflecting ratio of the disk-shaped recording carrier is changed, the rotating synchronizing signal can be easily taken out. A gate output generating circuit, after the circuit is sufficiently amplified so as not to receive the change of the signal level, triggers the circuit to generate a gate output 122 and therefore the circuit can stably generate the gate output 122.

Abstract: PROBLEM TO BE SOLVED: To measure the burial depth of a buried object from the ground surface easily and in a short time by operating based on the reflection time of transmitted electromagnetic wave from the buried object, the distance between the position and a vicinity position with equal reflection time and the reflection time from the transmission from above the ground surface, etc. SOLUTION: When a depth D of a pipe, for example, buried in the ground 1 is measured, a transmission and reception antenna 6 is firstly placed at the first position 3 on the ground surface and the necessary reflection time t1 from the transmission of electromagnetic wave to the reception after reflection at the pipe 2 is measured. Then, the second position 4 where the reflection time is t1 is determined by drawing the transmission and reception antenna 6 along the ground surface and the distance, 2v, between the positions 3 and 4 is measured. Next, the reflection time t2 is measured at the third position 5 where the transmission and reception antenna 6 is lifted up vertically from the position 4 by hm.

Abstract: PURPOSE:To obtain the present stable porous ceramic having high porosity, high purity, and excellent electrical and electronic characteristics by crushing the gel obtained by the hydrolysis of an alkoxide to a specified grain size, heating, and calcining the crushed gel in the vessel of desired shape at a specified heating rate. CONSTITUTION:The gel obtained by the hydrolysis of an alkoxide is crushed to 100-1000mum grain diameter, and the crushed gel is heated and calcined at a heating rate of >=600 deg.C/hr in the vessel of the desired shape. The gel consisting of the SiO2 obtained by hydrolysis under the influence of an acidic catalyst or the gel consisting essentially of SiO2 and a metal oxide is preferably used, since a good electrical characteristic is obtained. A vessel made of ordinary ceramics (e.g., alumina and mullite) can used as the vessel. However, a vessel made of carbon and SiC is most preferably used from the standpoint of mold releasabilty. An inert atmosphere is used from the midst of heating to prevent the oxidation of the vessel.
