Filed: 1996-10-23
Abstract: PROBLEM TO BE SOLVED: To improve the safety of an electronic lock by coding the discrimination signal to be transmitted from a key to the lock, and releasing the lock only when the key satisfies the conditions of collation. SOLUTION: A user presses a transmission button 3 to release a door lock. A first timer 4 of a key and a second timer 9 of the lock synchronously count the time, and the counting time is set to be 5 respectively. When the transmission button 3 is pressed, a coding part 5 of the key confirms that the counting time TS of the first timer 4 is 5, the square of the counting time TS is calculated, and 25 is outputted from a transmission part 6 to a lock 2 as the signal. A decoding part 11 of the lock 2 calculates 5 as the square root of 25 which is received, and the value is outputted as the counting time value T of the first timer 4. Then, a collation control part 12 operates the difference D between the counting time 5 and the counting time value 5 of the second timer 9 as 0 to confirm that the difference D is <=3.  If it is confirmed, the collation control part 12 drives a lock drive part 7 to transmit the signal to release the lock.

Title: Anti-fogging glass lens and its anti-fogging method
Inventor: SUGANO MITSUMASA
IPC: E01F9/615
Filed: 1996-09-17
Abstract: PROBLEM TO BE SOLVED: To prevent the fogging of a glass lens surface by the condensed water of moisture and/or water drops by providing this glass lens surface with a surface layer contg. transparent photocatalytic titanium oxide particles. SOLUTION: The layer contg. photocatalysts is formed on the surface of a base material. The glass lens surface is made highly hydrophilic according to the photoexcitation of the photocatalysts by having such surface structure. As a result, even if the moisture of the atmosphere condenses and sticks to the glass surface, the condensed moisture does not grow to the form of water drops and turns to the form of a uniform water film. The fogging of the glass surface by the condensed water of moisture and/or the water drops is prevented. In the case of Fig., the glass lens surface has a metallic element M and the extreme surface consists of a general inorg. oxide. This oxide exhibits hydrophilicity in the state that the contaminants in the environment are not adsorbed.  The oxide expels these contaminants by the photoexcitation of the photocatalytic titanium oxide incorporated into the surface layer exclusive of the inorg. oxide and is capable of forming the a uniform water film by forming adsorbed water layer.
