Title: Output amplitude controller
IPC: H03G3/02
Filed: 1992-03-18
Abstract: PURPOSE:To execute amplitude control by which a frequency characteristic and linearity are scarcely varied due to variable gain by inserting a first variable attenuator between a variable gain amplifier and a constant gain amplifier, and also, cascading a second variable attenuator to the constant gain amplifier. CONSTITUTION:Between a variable gain amplifier 11 and a constant gain amplifier 12, a first switching type attenuator 30 is inserted, and also, a second switching type attenuator 40 is cascaded to the constant gain amplifier 12. The attenuator 30 can switch an attenuation ratio to 4:1, etc., by an attenuation ratio control signal CT1, and the attenuator 40 can be switched to 100:1, 10:1, etc., by a fact that attenuators 41, 42 are switched by attenuation ratio control signals CT2, CT3. In such a way, an output level of the variable gain amplifier 11 is attenuated by the attenuator 30, therefore, in the case the output level is not the highest, amplitude of an output signal of the constant gain amplifier 12 is suppressed to a prescribed value or below, and deterioration of linearity and a frequency characteristic of the output signal is prevented.

Abstract: PURPOSE:To control the I-V property of a fuel cell, raise the discharge current of the cell stepwise in proportion to the temperature rise of the fuel cell, and shorten the time required for starting the cell without loss of a unit cell by finding the rate of voltage lowering i.e., dV/dI and d<2>V/dI<2> values in sequence according to the discharge current and discharge voltage of the fuel cell which are detected when the cell is started. CONSTITUTION:The output circuit of a fuel cell stack 6 is provided with a current detector 7 and a voltage detector 8 and thus the discharge current I and discharge voltage V of the fuel cell are detected when needed, and a change in the I-V value between two close points of time is calculated by an arithmetic and control portion 9. The values of dV/dI and d<2>V/dI<2> i.e., the rate of lowering of the output voltage to the rate of increase of the discharge current of the fuel cell detected when the cell is started, are calculated when needed, and, when the d<2>V/dI<2> is less than 0 and also the dV/dI value is dropped to a predetermined level, the discharge current is maintained at a fixed value to heat the fuel cell. When the discharge voltage V is raised to a predetermined value the discharge current I is increased and a series of control for maintaining the discharge current constant in a predetermined level approximating the dV/dI value is repeated so that the fuel cell is heated to its working temperature.

Title: Ventilation device
Inventor: HAYASHIDA YUKIO
IPC: F24F7/06
Filed: 1985-04-30
Abstract: PURPOSE:To make the movement of a movable hood at a constant, moderate speed from the start of its opening till its completion by a constitution in which a resilent member that presses the movable hood outwardly, a damper and a lock mechanism are provided, and energized force of the damper wanes as the movable hood opens wider. CONSTITUTION:A movable hood 22 on the front face is energized to be opened by a spring 23. When the front side is pushed, the lock mechanism 35 is released to allow the movable hood 23 to open to the front side. At this moment, the piston 31 of a slide damper 32 moves in the direction of its compression, which is joined by the resistance of a rotative damper 27 to generate a large damper force. When passing by the neutral point, the piston of the slide damper 32 moves in the direction of its extension, leaving the rotative damper 27 as a sole damper force. When the spring force of the spring 23 is large,the damper force is also large, and, as the spring force diminishes as the spring is contracted, the damper force also wanes, and so, the movable hood 22 will not suddenly open, but slowly.

Then, after crude oil A is flowed in the tank, a valve 4 is closed to make the tank airtight. Then, when the air in the tank 1 is discharged and the liquid 9a falls to the position of (b), a valve 14 is closed and a three-way valve 11 is changed over to make the air flow in the tank 1. At the same time, the stopwatch is operated and when the liquid 9a returns to the position of (c), namely, the 2nd pressure, the watch is stopped to measure the time T1. After that, the time T2 is measured everytime the crude oil is discharged in the same order and the filling rate of othe crude oil A can be calculated from the difference among T0, T1, and T2.
