Title: Power amplifier and electronic device using it
Inventor: MEJIKA KENICHI
IPC: H03F1/02
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To provide the power amplifier with a small power loss and the electronic device using it. SOLUTION: A down-converter is formed by a FET 21, a diode 22, a coil 23 and a capacitor 24. A comparator 25 compares a voltage Va at a power supply terminal 11a of an amplifier section 11 with a comparison voltage Vsz1 to apply A discrimination signal CPA to a drive signal generating section 51. A reference signal generating section 53 applies a reference signal CLK to the signal generating section 51. The signal generating section 51 generates a drive signal SWA based on the signals CLK, CPA to drive the FET 21. When an output signal SOUT is small, a voltage (power supply + VPL) is fed to an amplifier section 11 via a diode 26. When an output signal SOUT is large, a voltage (power supply + VPH) is fed to the amplifier section 11 while being reduced by the down-converter depending on the signal SOUT. The negative side configured similarly to above.  Thus, the power loss of the amplifier section 11 is reduced. Reception interference of the down-converter due to noise is relieved by varying a frequency of the reference signal CLK depending on the channel selection of a tuner.

Title: Fixing device
Inventor: FUKANO MASAHIKO
IPC: G03G15/20
Filed: 1989-02-23
Abstract: PURPOSE:To surely carry not only plain paper but also film without occurring a carrying defect and wrinkles by providing a pressure belt via a unidirectional clutch permitting the floating of the pressure belt in a paper carrying direction so that the belt can rotate and drive in the paper carrying direction and setting the circumferential speed of the pressure belt equal to or lower than that of a heat roller. CONSTITUTION:When plain paper is used, the heat roller 51, the plain paper and the pressure belt 52 are easy to slip, and therefore the pressure belt 52 does not follow the circumferential speed of the heat roller 51, but is driven at a predetermined circumferential speed via the unidirectional clutch F. Conversely, when film having excellent adhesion is used instead of paper, the clutch F permits the floating of the pressure belt in the paper carrying direction. Since the film sticks both to the heat roller 51 and to the pressure belt 52, the pressure belt 52 follows the heat roller 51 rotating at a circumferential speed higher than that of the pressure belt 52, and rotates in synchronization with the heat roller 51. Thus, the plain paper is surely carried, while the film is carried without the speed difference to eliminate wrinkles and damage.

Title: Traffic flow simulation system
Inventor: MORI HIROKO
IPC: G08G1/00
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To improve prediction precision by bringing a traffic flow simulation close to the real flow. SOLUTION: When one node exists in an arrival mesh and the two nodes exist in a departure mesh, a departure node is selected in terms of probability by a formula Pj=(Rj-αJj)/ijΣn(Rj-αJi). Here, Rj is the weight coefficient of the node j(Nj), α is an adjustment parameter for optimizing the simulation system and n is 2. Besides, Jj is the congestion level of the node j, is 1 in the case of spill-back in a link connected to the node j and is 0 in the opposite case. When the departure node is selected by a probability Pj, the probability for selecting the node j as the departure node is changed by the congestion level Jj of the node j obtained by the simulation system so that congestion in the departure mesh is mitigated, and the simulation of the more realistic traffic flow is enabled.

Title: Speed controller for car
Inventor: TANIGAWA MITSUARI
IPC: B60K31/08
Filed: 1982-03-23
Abstract: PURPOSE:To ensure quick actuation of the engine brake in a retard mode, by turning on and off a retard switch to release and retard the overdrive, respectively. CONSTITUTION:A signal (a) is obtained by giving an F/V conversion to a car speed signal and then compared 101 with the output (b) of a memory 102 storing the voltage equivalent to the speed of car after turning on an analog switch 103 at a speed to be set. Then the signal is supplied to an inhibiting circuit 105 with compensation 104 of lead angle and then driven 106. Thus a control valve coil 108 within a negative pressure type actuator is controlled to hold a desired speed. When a retard switch 110 is turned on, the circuit 105 is actuated with the coil 108 inactivated to set the generating output of the actuator at zero. At the same time, a cutoff coil 109 within an overdrive controller 111 is made to conduct to release the overdrive. Thus the function of an engine brake is increased. As a result, the deceleration is assured at a high speed to avoid collision.
