Title: Skew detection circuit
Inventor: ISHIZUKI HITOSHI
IPC: G01R25/00
Filed: 1991-09-04
Abstract: PURPOSE:To obtain a skew detection circuit which does not require any oscilloscope. CONSTITUTION:A first and second flip flops 8 and 9 respectively latch the logical levels of signals to be adjusted outputted from first delay circuits 4, 5, and 13 and the logical levels of inverted signals to be adjusted outputted from second delay circuits 6, 7, and 14 synchronously to the variation of the logical level of the output of a reference delaying element 3. When an OR circuit 10 detects that the logical level of the output of the first flip flop 8 coincides with that of the output of the second flip flop 9, the circuit 10 detects that the signals to be adjusted do not advance from a reference signal by the difference between a first delay and reference delay (first delay - reference delay) and do not delay from the reference signal by the amount equal to the difference between the reference delay and a second delay (reference delay - second delay).

Title: Surface-protective grave stone and surface protection method of grave stone
Inventor: YOSHIMURA TSUNESHIGE
IPC: C04B41/49
Filed: 1996-08-27
Abstract: PROBLEM TO BE SOLVED: To retain the beautiful surface of a grave stone which are not stained with ease and which are not chemically eroded, for a long time, by covering the whole surface with a protective skin having siloxane bonds. SOLUTION: The surface of a lower base stone 1, an incense burner 2, a middle base stone 3, a water bowl 4, an upper base stone 5, and a tombstone 6 constituting grave stones, is sufficiently washed and dried. Subsequently, a surface-protective agent chiefly made of a siloxane condensation product is applied by a spray gun or the like on the whole face including the bottom face of the constituting members 1-6 to form a surface protection skin film after curing at the normal temperature. Since the protection skin film coating the surface of grave stones contains siloxane bonds in the molecular structure, it is chemically inert and hence, excellent in anticorrosiveness, water-repellent effect, and water-imperviousness. As a result, it prevents oxidizing chemical substances in rainwater from eroding the surface of the grave stones.  Even if they are stained, the stains can be easily removed by washing. Accordingly, the surface of the grave stones can be beautifully retained for a long time.
