A wireless communication system includes a plurality of terminals connected via at least one wireless network. Each of the plurality of terminals identifies a wireless network to which the terminal is to be connected by using a group identifier including a terminal identifier of an issuing terminal that issues an attribute certificate and a first identifier that is set for the issuing terminal.

A process for providing a coating on a surface of a substrate made of magnesium or magnesium alloy has a step of heating the substrate in a humidified atmosphere therein. It is desirable that the atmosphere has a temperature between 50 and 450 degrees centigrade and a relative humidity between 50 and 100%. It is also desirable that the atmosphere has a pressure between 1.0×105 and 1.0×106 Pa. Further, it is desirable that a thickness of the coating is between 3 and 50 μm. The surface treatment process is suitable for forming a vehicular part such as an ECU case.

A gene coding for a mutant tyrosine repressor having increased positive regulatory activity for expression of the tyrosine phenol lyase gene compared with a tyrosine repressor not having mutation is obtained by introducing a mutation into a tyrosine repressor gene of Erwinia herbicola, introducing the gene into which the mutation is introduced into Escherichia coli expressing a lactose operon under the control of a promoter and enhancer of the tyrosine phenol lyase gene derived from Erwinia herbicola, and selecting a transformed strain having increased β-galactosidase activity.

Each terminal in a wireless ad-hoc communication system includes an encryption-key management list table 660. The encryption-key management list table 660 stores, in association with a terminal identifier 661 such as a MAC address, a unicast encryption key 662 for use in unicast communication with a terminal identified by the terminal identifier 661, and a broadcast encryption key 663 used when the terminal identified by the terminal identifier 661 performs broadcast communication. Therefore, a broadcast encryption key is provided for each terminal that performs broadcast communication, and the broadcast encryption keys are managed by the individual terminals in an independent and distributed manner. This allows independent and distributed management of broadcast encryption keys in a wireless ad-hoc communication system.

An end surface of a stopper is formed so as to be thick which is substantially the same surface as an outer circumferential surface of a flange portion, and the stopper is engaged with an engaging groove formed at the flange portion, whereby an engaging portion formed at a locking piece of the stopper is elastically deformed and engages with an engaging portion formed at the flange portion. When the stopper is pulled out in the direction away from the surface of the base resisting with elastic force of the engaging portion, an opening portion of a slot can be opened. The paper cutter of the invention enables to take the slider out of a plate in spite of having a simple configuration, and prevent a falling of the slider from the plate even in conveying it.

A magnetic field sensor in which a magnetic film or films having a magnetoresistance effect for detecting a magnetic field and a conductor electrode film for applying a current to the magnetic film are deposited on a flexible substrate. Therefore, the magnetic field sensor deposited on the flexible substrate can be bent as desired. The magnetic film or films can be deposited on one face of the flexible substrate made of resin that is 5 to 300 &mgr;m thick while the other substrate face on the opposite side of the flexible substrate can be brought adjacent to a body inducing a change in a magnetic field that is undergoing detection. be deformed.

A clock signal generating circuit of the present invention switches the threshold value of a buffer circuit included in an output buffer section substantially when the oscillation output of an oscillating section is stabilized, thereby generating a clock signal. The clock signal plays the role of a clock signal for a stabilization detecting circuit at the same time. Therefore, once the oscillation is stabilized, clock components other than a clock signal whose duty cycle is 50% and which would bring about noise are obviated. This allows the clock signal output from the clock signal generating circuit to remain stable.

A method of producing a photosensor having a photoconductive layer and a pair of electrodes provided through an ohmic contact layer on the same surface of the photoconductive layer for applying a voltage to the photoconductive layer. The method comprises the steps of: forming an insulating layer on one surface of the photoconductive layer except at portions where the pair of electrodes is to be formed; forming a layer of an ohmic contact layer forming material on the insulating layer; forming a layer of an electrode forming material on the layer of an ohmic contact layer forming material; and removing the electrode forming material except at the portions where the pair of electrodes is to be formed, and the ohmic contact layer forming material.
