Title: User certification system
Inventor: OKAMOTO TATSUAKI
IPC: G06Q40/00
Filed: 1984-06-15
Abstract: PURPOSE:To reduce stored information for a device which performs certification processing to a single piece regardless of the number of users while taking a countermeasure to the electrical interception of transfer information and stored information by using an open key decoding method. CONSTITUTION:A system control unit generates the password of each user in secret by using information that only the unit holds in secret and the identification number of each user, and when a user requests certification processing with a card 5, a certification processing unit 4 generates a random number (r) and passes the control to the card 5. The card 5 generates a value S on the basis of the random number (r) sent from the unit 4 and PW1 and (n) held in registers 51 and 52 and sends it to the certification processing unit 4 together with ID1 from a register 53. The certification processing unit 4 by generate S<e> and HrID<1> by exponent congruence computing elements 44 and 45 with (e) and (n), random number (r) of the random number generator 43, and S and ID1 received from the card 5, so that the user is certified as a correct user when S<e>identicalrID<1> and (modn) are satisfied.

Title: Video receiver
Inventor: YOKOGAWA MASAHIRO
IPC: H04N5/44
Filed: 1989-05-17
Abstract: PURPOSE:To prevent cross modulation and deterioration in the S/N even when strong and weak electric field signals are in existence by supplying a signal with a prescribed electric field strength to a tuner circuit independently of the electric field strength of an input signal. CONSTITUTION:A gain control signal is sent to a tuner circuit 3 and a control circuit 11 based on a control signal from an intermediate frequency detection circuit 4 by an RF-AGC circuit 6. When the gain control signal is maximum (full gain signal), the control circuit 11 turns off a changeover switch 10b and connects a changeover switch 10a to the position of a booster circuit 9 to control the amplification quantity so that the output of the RF-AGC circuit 6 is an optimum value. When the output of the RF-AGC circuit 6 is minimum, the control circuit 11 turns off the changeover switch 10b to connect the changeover switch 10a to the position of an attenuator 8 so as to control the attenuation, thereby optimizing the output of the RF-AGC circuit 6. Thus, the gain attenuation of the tuner circuit 3 is set to be small.

Title: Thermal head presser
Inventor: KUROSE KAZUYOSHI
IPC: B41J2/32
Filed: 1988-05-20
Abstract: PURPOSE:To prevent color misregistering and perform color transfer with high image quality, by a construction wherein a fastening part for connecting a thermal head and a head-pressing lever to each other is composed of a fastening member having an elastic element. CONSTITUTION:Head-pressing lever projections are positioned in a direction perpendicular to the longitudinal direction of a platen 4. One end of an elastic element 7a possessed by a fastening member 7 is brought into contact with or attached to the fastening member 7, and the other end is brought into contact with or attached to a flat surface of a head-pressing lever 5, 6, thereby absorbing dispersions arising from the contact of heat generating elements 1a with the platen 4 on only one side. Even when the non-uniform contact of the heat generating elements 1a with the platen 4 occurs due to dispersions in dimensional accuracy of component part, the dispersions arising from the non-uniform contact are automatically absorbed, whereby thrust play at a fulcrum for turning a thermal head 1 can be eliminated. Therefore, it is possible to maintain accurately the positional relationship of the heat generating elements 1a of the thermal head 1 with a recording paper 3, to prevent color misregistering, and to obtain a color image with high image quality.
