摘要： PURPOSE: To provide an ID authentication system disabling duplication of a key even in the case that a content of a communication between a first and a second entities is intercepted by a third party. CONSTITUTION: An ID code A common to a first and a second entities is shared between them. The second entity side multiplies the ID code A by a random number R1 and calculates a message on (= A○1 ) and sends it to the first entity side. The first entity side divides n1 the ID code A to calculate the random number R1 . Thus, the key is judged as a right one only when the message is divisible by the ID code A. Since there is little probability that a random number is coincidentally divisible by the ID code A, the rightness of the key can be authenticated in a high probability.

摘要： PROBLEM TO BE SOLVED: To surely operate a lock main body without the need of power supply through a signal conductor to the lock main body and battery exchange in an electron lock where data is mutually communicated for identification and collation between a key and the lock main body. SOLUTION: A battery 34 of a key 32 functions as a power supply for the key 32 and the lock main body 30. Power transmission is performed simultaneously with data transmission to the lock main body 30, and the transmitted power is accumulated in a capacitor by a power supply circuit 54. The power is used to conduct transmission from the lock main body to the key and drive an actuator 62. A control part 36 effectuates the use of a key only in a designated time zone. If the life of the battery 34 becomes short, a warning is given to an indicator 40.

摘要： PURPOSE:To obtain an actuator whose structure is simplified, which is miniaturized and whose performance is made highly efficient by a method wherein magnetic fluxes by a permanent magnet are added or subtracted and made to flow in respective gaps formed between the S-pole and the N-pole as fixed magnetic poles and a rotary magnetic pole. CONSTITUTION:One out of magnetic fluxes by a permanent magnet 12 flows to a magnetic substance 28 for a fixed magnetic pole 16 via the end part of a rotary magnetic pole 46 from a magnetic substance 24 for a fixed magnetic pole 14, and the other flows to a magnetic substance 26 for the fixed magnetic pole 16 via the end part of the rotary magnetic pole 46 from a magnetic substance 22 for the fixed magnetic pole 14. On the other hand, a magnetic flux by an exciting coil 48 flows to the length direction of the rotary magnetic pole 46, it is divided into two directions of the magnetic substance 24 and the magnetic substance 28, divided magnetic fluxes flow in the magnetic substances 24, 26 for the fixed magnetic poles 14, 16 from one end of the rotary magnetic pole 46 to the lower part, they flow in the magnetic substances 22, 26 for the fixed magnetic poles 14, 16 via base parts 18, 20 to the upper party, and they flow to the other end of the rotary magnetic pole 46. At this time, a difference is caused in the composite flux density of the magnetic flux by the exalting coil 48 and the magnetic flux by the permanent magnet 12 in gaps 50, 56 and in gaps 53, 54, and a rotor 30 is turned.

摘要： PURPOSE: To make the motion of a connecting pin sure and to reduce consumed electric power in a lock cylinder. CONSTITUTION: Two rotary bodies 30, 32 is rotatably connected through a connecting pin 44. In the connecting pin 44, a return spring and a feed spring being weeker than the former are in action. When a key 14 is inserted, the action of the return spring is released, and a stud on the connecting pin 44 is caught by a trigger 46. When the trigger 46 is rotated by an actuator 38, the connecting pin 44 engages in an engaging hole 32B. When the key 14 is pulled out, the return spring acts on the connecting pin 44 to return it to an original state. In this case, the trigger 46 makes its comeback. A magnetic conductive member 22 is arranged in front of a lead switch 20 serving as a magnetic force sensor, and a judging section for deciding the effective term of the key 14 and a preparing section for preparing the use past history information of the key 14 are provided in an electronic circuit 16.

摘要： PURPOSE:To provide an electronic lock that stably operates with limited watt consumption. CONSTITUTION:When an electronic key is inserted into a keyhole, a push plate 20 is pushed, and a key rod 21 is shifted, removing a latch of a plate spring 24 which is meshed with a spiral groove 29 of a turning shaft 28 of a motor 27 by dint of magnetic force of two magnets 24 and 25. In the case where the certified data transmitted from the electronic key is aright, the motor 27 operates and thereby the plate spring 24 shifts along the spiral groove 29, while a coupling pin 23 is projected to the outside of an inner cylinder 16, and it moves into an opening part 34 of a clutch disk 31 installed in a bolt driving shaft 30. In this state intact, the electronic key, the inner cylinder 16, and the bolt driving shaft 30 are integrally rotated, so an electronic lock is made lockable. When the electronic key is pulled out, the key rod 21 is shifted to some extent by dint of a spring 22, removing the plate spring 24 from the groove 29, and it is latched at the keyhole side. With this constitution, the coupling pin 23 is also housed in the inner cylinder 16, and thus the connection between the inner cylinder 16 and the bolt driving shaft 30 is released free.

摘要： PURPOSE:To provide a liquid spray device which does not give a sense of incompatibility though being installed in a shop or the like and surely sprays a liquid as a mark to a criminal by constituting a cover provided with through holes correspondingly to nozzles in the front. CONSTITUTION:A liquid spray device 10 is operated by the command from an alarm device to spray the liquid as a mark to the standing criminal, and this liquid is stuck to his clothes or the like. In this case, a cover 30 with which a main body 11 is covered, has the logo type of the manufacturing company, the shop name, a pattern, or the like formed in the front face by many small through holes 31, and recessed parts 32 are provided in through holes 31a corresponding to nozzles 20a. When the main body 11 will be covered with the cover 30, nozzles 20a are fitted to recessed parts 32 to position the cover 30, and nozzles 20a face the through holes 31a. Consequently, only many through holes 31 are seen when the alarm device is seen from the front, and it cannot be found that nozzles 20a exist, in the inside.

摘要： PURPOSE:To prevent pollution of articles, commodities, or the like when spraying a liquid as a mark to a criminal, by recovering the liquid, which is not stuck to his cloths or the like or is sprayed after his escape, into a liquid recovery part. CONSTITUTION:When a burglar robs of money or other articles and comes to a position before a door 2, he temporarily stops before the door 2 because the door 2 is opened at a low speed. A human body detecting sensor 8 for exit detects him and sends the detection signal to an alarm device 5 through a door controller 6, and the alarm device 5 gives an operation command to a liquid spray part 10 basing on this signal. Then, the pressurized liquid in a cylinder is pushed out to a pipe and is sprayed as the mark to the burglar from a nozzle and is stuck to his clothes or the like. All of the liquid which is sprayed from the nozzle of the liquid spray part 10 but is not stuck to his clothes or the like, and the liquid sprayed from the nozzle after his escape, are recovered into a liquid recovery part 40.

摘要： PURPOSE:To improve an operability, a collation rate and a maintainability by isolating the internal part of a fingerprint input part at the time of a non- action from an external part for an operating body, and moving the operating body only when accepted person conditions to be inputted coincide with conditions to be specified beforehand. CONSTITUTION:When the fact that an inputted password is of a just user is judged by an accepted person decision means 611, an electromagnet 114 is demagnetized and turned off. Thus, when the user pushes an operating body 115 with a finger, the operating body 115 can be pushed towards a limit switch 32. As to fingerprint input image data, when the fingerprint of the finger to push the operating body 115 is inputted and the limit switch 32 is turned on, the feature part is extracted. Fingerprint data to be registered beforehand and fingerprint data to be inputted are compared and checked, and a result is outputted from a check result output part 3. When the user retracts the finger meanwhile, the limit switch 32 is turned off, and an electromagnet energizing means 614 energizes the electromagnet 114. Thus, the finger of the user is pressed out along with the operating body 115.
