Abstract: PROBLEM TO BE SOLVED: To simply request the issuance of a personal certificate with no mistake even in the environment where subject names are separately described in different hierarchies. SOLUTION: The issuance of the personal certificate is requested with a client terminal 201 in a cooperating company. An applicant inputs a personal ID, a name, a mail address, a place to make contact, and a model registration ID. The request content synthesizing section 102c of an application server 102 receives a request content, synthesizes the directory information required for the request of the personal certificate in reference to a model database 109 and a project database 108 from the model control ID of the request content, and registers the directory information on a certificate database 110. A certificate issuing section 102d receives a public key from the public cipher key generating mechanism of the browser at the client terminal 201 of the applicant and generates and transmits the certificate to the applicant.

Title: Microcomputer
Inventor: ISHIMARU HISAAKI
IPC: G06F9/48
Filed: 2000-11-13
Abstract: PROBLEM TO BE SOLVED: To eliminate a dead zone where standby can not be released in a microcomputer that can not perform standby release without applying interrupt processing to a prescribed vector table by interrupt. SOLUTION: When an interrupt occurs after setting a flag f-stb during standby showing that processing including an instruction for making the microcomputer to be in a 'standby state' is being carried out in a step S41 and also by the time when a 'stop' instruction is carried out in a step S43 while a standby inhibition flag f-denstb being a flag showing that the interrupt occurs is not set, a stack pointer is rewritten to the address of a step S50 being the return destination of a cpustop subroutine and is subsequently retuned in a step S74 in interrupt processing, and the microcomputer is therefore prevented from being in the 'standby state' without going through the 'stop' instruction in the step S43.

Title: Variable attenuator
Inventor: KAWAMURA MASAAKI
IPC: H03H7/06
Filed: 2000-11-30
Abstract: PROBLEM TO BE SOLVED: To provide a resonance type variable attenuator which can be secured for a good low insertion loss characteristic and a high attenuation characteristic over a wider band. SOLUTION: The variable attenuator 40 uses two stages of LC parallel resonance circuits. A serial connection between the LC parallel resonance circuits 3 and 4 of the two-stage structure is connected to a reference potential point via a capacitor 41, while it is also connected to the reference potential point via a high frequency variable resistor element 9. When the control voltage Vc=0, high frequency variable resistor elements 5, 6, 7a, 7b, and 9 are turned into an off-state and therefore serve as a LC low-pass filter, and a pass-band characteristic of a high frequency signal has a low loss and becomes nearly constant over a wide band up to the cutoff frequency of the LC low-pass filter.  When the control voltage Vc is large, the high frequency variable resistor elements 5, 6, 7a, 7b, and 9 are turned into an on-state and therefore serve a LC parallel resonance preventive filter, providing the maximum attenuation to a high frequency signal near the parallel resonance frequency of the filter.
