Title: Differential amplifier circuit device
Inventor: NAMIKAWA TAKESHI
IPC: H03F3/45
Filed: 1992-02-18
Abstract: PURPOSE:To improve input/output characteristic extending over from an active area to an inactive area by providing an NPN transistor(TR), a resistor for current injection, and a PNP TR newly in a differential amplifier circuit. CONSTITUTION:An inrush current I4 flows on the collector of the TR Q2 via a resistor R3 even when an input signal voltage Vi on the positive side is increased and the emitter current of the TR Q2 is decreased. Therefore, the internal emitter resistance re2 of the TR Q2 is not so much increased, which keeps relation R1>>re2, re1. Therefore, the deterioration of linearity due to the increment of the internal resistance re can be prevented from occurring. The TR Q4 functions as a limiter which prevents the reverse voltage of the TR when the TR Q3 is cut off due to excess over the dynamic range of the differential amplifier circuit by the input signal Vi, and the emitter voltage of the TR Q3 jumps steeply. As a result, the input/output characteristic extending over from the active area to the inactive area can be improved.

Title: Float melting device and its method of molten metal output
Inventor: FUJITA MITSURU
IPC: F27B14/20
Filed: 1994-03-02
Abstract: PURPOSE:To control the output timing and amount from a molten metal which is prepared by putting in small solid pieces and allowing to grow. CONSTITUTION:An induction coil 20 consisting of an upper coil 21 and a lower coil 22 is installed at a crucible in such a way as surrounding it, which is equipped at the bottom with a flowout hole 13, wherefrom a molten metal 5 is taken out. If the current in the lower coil 22 fed from AC mains 32 is lessened, the buoyancy of the molten metal 5 lessens because it is proportional to the square of the amperage approximately, and the level of the molten metal 5 sinks, which enables output. Therefore, output can be done when it is desired by controlling the current in the lower coil 22.

Title: Speed change control device for continuously variable speed change gear
Inventor: IINO HISAFUMI
IPC: F16H59/54
Filed: 1989-02-10
Abstract: PURPOSE:To prevent the occurrence of an engine stop by a method wherein the target number of revolutions is adjusted to a low value responding to an approximately fully closed opening by braking during running to apply engine brake the change gear ratio of which is minimum, and when a car speed is decreased to a given value due to deceleration, the target number of revolutions is increased for correction. CONSTITUTION:A shift control valve 250 controls a servo unit for a second speed change by means of the pressurizing force of a second cam 171 of a throttle cam mechanism 150, i.e., the press force of the target number of revolutions of an engine responding to a throttle opening, and a governor pressure from a governor 8, and controls a change gear ratio. When a brake is worked during running, i.e., when an accel pedal is released from step-on, the low target number of revolutions responding to approximately full closing of a throttle opening is set, and engine brake is applied in a state that a change gear ratio is left minimum. However, when a car speed is decreased to a value lower than a given value due to deceleration, a control circuit 100 opens a second solenoid valve 285 to increase the target number of revolutions, set by the shift control valve 250, for correction, and a gear is shifted to the low side. This constitution enables prevention of the occurrence of an engine stop.

Meanwhile each channel 400 contains a channel number discriminating circuit which discriminates the channel number of the input information and a channel-based control circuit which transfers the input information to the corresponding channel when the channel number does not indicate its own channel.

Title: Device and method for controlling writing-in of flash memory
Inventor: HIGASHIDE TOMOFUMI
IPC: G11C16/02
Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To prevent a writing-in level from being upgraded due to that a flash memory is repeatedly written in and to prevent the deterioration in the precision of a holding test. SOLUTION: This device consists of a flash cell array section 11, a writing-in section 12 which stores writing-in object binary data and writes the data into the section 11, and a reading out section 17 which reads the data written in the section 11 and stores the data. An inverter 22 is arranged between the sections 12 and 17 to reverse binary data read from the section 17. The reversed binary data, which are reversed by the inverter 22, are reset as writing-in object binary data of the section 12. By properly setting initial setting values of the sections 12 and 17, a performance test is made faster and deterioration in the test is prevented. Thus, the increase in a writing-in level of arbitrary writing-in data is eliminated for an arbitrary write-in data by the physical characteristics of a flash memory in sigular or plural steps of repeated writing-ins.
