Title: Dc/dc converter
Inventor: TATEISHI TETSUO
IPC: H02M3/155
Filed: 1998-05-11
Abstract: PROBLEM TO BE SOLVED: To provide a DC/DC converter capable of holding an output voltage, even in the case where the difference is small between an input voltage to be supplied and the output voltage to be held. SOLUTION: A feedback amplifier 1 generates a control signal Icnt1 based on an output voltage Vout and a reference voltage Vref, whereas a ramp signal generating circuit 3 generates a ramp signal Ramp 3 synchronized with a pulse signal from an oscillator 2. A ramp signal generating circuit 11 generates a ramp signal Ramp 11 in accordance with the state of a latch circuit 1. A comparator 12 generates a reset signal at the time when the sum of each level of the ramp signals Ramp 3 and Ramp 11 has become larger than that of the control signal Icnt1. The latch circuit 5 is set by the pulse signal from the oscillator 2, and reset by the reset signal. A driver D1, provided with a capacitor Cx for boosting, drives switches S1 and S2 in accordance with the state of the latch circuit 5.

Title: Broad band amplifier circuit
Inventor: SAITO HIROSHI
IPC: H03F3/34
Filed: 1989-05-19
Abstract: PURPOSE:To widen a dynamic range of an output with a low power voltage by forming a current mirror circuit with a 6th NPN transistor(TR) and a 7th NPN TR and setting a base potential of a 8th NPN TR to a low level. CONSTITUTION:An input current fed to an input terminal 1 is subject to current- voltage conversion by using resistors R1, R3, R4 and the converted voltage is given to an emitter of an NPN TR 3. The voltage is amplified further by using resistors R6, R7 and since the level of the base of the NPN TR 7 is fixed to nearly 0.7V, the reference voltage V2 of a 2nd reference voltage source is decreased to nearly 1.4V. As a result, the amplitude of the output voltage is taken a maximum of (power voltage Vcc1-1.4)/2, and since the dynamic range of an output signal depends on a difference voltage between the power voltage Vcc1 and the reference voltage V2, a wide dynamic range is taken even when the power voltage Vcc1 is low.

Filed: 1985-06-12
Abstract: PURPOSE:To perform continuous position measurement even in an area where there are many shield bodies by selecting a satellite corresponding to the configuration of an area where a vehicle runs. CONSTITUTION:A map geographic information storage part 5 is divided into a suburb area and an urban area and the positions and heights of mountains are recorded in the suburb area; if there is a satellite from which a signal can not be received because of the positions and heights of the mountains, the satellite is excluded from a satellite selection. Further, a satellite selecting part 7 receives data from the storage part 5 to decide whether an automobile runs in a suburb or urban area, and selects a suburb or urban satellite selecting method to determine a satellite for position measurement. When the urban satellite selecting method is selected, a satellite from which a signal is received without any shield body is selected as the satellite for position measurement and satellites which has low possibility of reception, but is in the moving direction of the automobile and perpendicular to the moving direction are selected. When those satellites enter a receivable state, excellent HDOP (horizontal precision diversion) is obtained and a GPS navigation device is capable in continuous position measurement.

Title: Detection of cutting completion of cast slab in vertical type continuous caster
Inventor: YOSHINAGA TSUTOMU
IPC: B22D11/16
Filed: 1992-04-20
Abstract: PURPOSE:To stably detect the cutting of a cast slab only by the improvement of a control circuit without arranging a detector at mechanical equipment side, by detecting the cutting completion of the cast slab based on a signal showing that descending velocity of a carrier excesses the carrier velocity preset in the reverse hanging down characteristic range. CONSTITUTION:When the cutting of the cast slab completes, the wt. of the cut cast slab is loaded to a receiving table 5, and as a torque TD needed to support the wt. is larger than a torque TC, generated at the time of synchronously driving, the carrier 5 can not support the wt. and starts to descend at a velocity VD higher than the casting velocity VC. A torque command function generator 16 is made to increase the torque command to the ascending direction so as to restrain the velocity VD when the receiving carriage laying the cut cast slab starts to descend at the quicker velocity than the casting velocity. As the difference between the velocity VC at the time, when the carriage 5 synchronously descends with the cast slab and the velocity VD descended while loading the cast slab is generated, this difference can be detected as the completion in the cutting of the cast slab by an excess velocity detecting circuit 17.
