Title: Cooling device for electric car
Inventor: OOHARA TAKAHIDE
IPC: F28D1/053
Filed: 1994-06-29
Abstract: PURPOSE:To provide an electric car cooling device which is capable of securing a satisfactory cooling performance with saved electric power. CONSTITUTION:A cooling device 13 is provided with a cooling unit D which comprises a liquid heat exchanger 3 and an air-cooled heat exchanger 4 and a radiator 9 which constitutes a coolant circuit with the liquid heat exchanger 3 and an electric motor-driven pump 11. The radiator 9 is designed to cool a coolant by emitting the heat of the coolant when receiving the air supply of a motor-driven fan 12. The motor-driven pump 11 is interposed by a coolant pipeline 10 which is connected like a ring between the liquid heat exchanger 3 and the radiator 9 and operates under the power supply from a control device 13, thereby circulating the coolant between the liquid heat exchanger 3 and the radiator 9. The control device 13 drives the motor-driven pump 11 and the motor-driven fan 12 when the detection temperature T of a temperature sensor 14 which detects the temperature of electric components 2 exceeds the setting temperature T1 while it stops the drive of the motor-driven pump 11 and the motor-driven fan 12 when the detection temperature T1 is less than the setting temperature T1.

Title: Variable gain amplifier
Inventor: OSADA HIROKAZU
IPC: H03G3/30
Filed: 1990-06-06
Abstract: PURPOSE:To prevent oscillation from generating even when an input signal is enlarged and a feedback gain is reduced by forming a load part to decide the non-feedback gain of an amplifying part as a variable impedance element so that the impedance can be small when the input signal is large and the impedance can be large when the input signal is small. CONSTITUTION:In the variable gain amplifier having a dynamic range equipped with a negative feedback means 1 to enlarge the gain when the input signal is small and to reduce the gain when the input signal is large, the load part to decide the non-feedback gain of an amplifying part 2 is formed with a variable impedance element 3 so that the impedance can be small when the input signal is large and the impedance can be large when the input signal is small. Namely, inversely connected diodes D1 and D2 are parallelly connected to a resistor R1 for deciding the non-feedback gain, and a bias V1 is loaded by using diodes D3-D5 so that potentials can almost be equal at both ends of the diodes D1 and D2 when there is no input signal. Thus, since the gain is reduced by the negative feedback means 1 when the input signal is large, the non- feedback gain is reduced as well, and no oscillation is generated.

Title: On-column type electric conductivity detector for electrodynamic separation with microcolumn
Inventor: RICHIYAADO ENU ZARE
IPC: G01N15/10
Filed: 1988-06-16
Abstract: PURPOSE: To detect a chemical seed for changing electroconductance with a high sensitivity by providing a micro column in cylindrical pipe shape with a diameter of approximately 25-200μm and an on-column-type electroconductance electrode that forms a boundary on at least the same plane with the wall part. CONSTITUTION: A tube 10 is filled with an electroconductive liquid 11 and a cation 12 is contained in a wall part. The cation 12 attracts an anion 13 from the liquid and forms an electrical double layer 13. As a result, the body of the liquid 11 is electrified by a net excessive positive electric charge. Therefore, when a potential of for example 30KV is applied between electrodes 15 and 16 located at both edge parts of the column of the liquid 11, the liquid 11 moves toward the cathode 16. A chemical species 18 of cation in the liquid 11 is attracted by the cathode 16 by cataphoresis and the chemical seed 19 of anion is repelled by the cathode 16.  When, for example, the chemical species 18 and 19 pass between detectors made of electrodes 21 and 22, they are measured between the electrodes 21 and 22, thus changing the electroconductive characteristics that depend on the difference between a background and a sample. The diameter of the electrodes 21 and 22 is approximately 0.01-0.75 (especially 0.60) times the inner diameter of the tube 10.

Abstract: PURPOSE:To obtain a speaker with low driving force distortion for which a constant driving power can be obtained over a wide range and is provided with a small magnetic circuit with superior symmetric property for flux density even when a voice coil is moved to an area outside a magnetic gap. CONSTITUTION:A magnetic circuit is formed of a center pole 12, a yoke 16, a magnet 13 joined with the inner peripheral surface of the yoke 16, and a top plate 14 and an under plate 15 respectively joined with the upper and lower surfaces of the yoke 16. The inside diameter of the magnet 13 is made equal to that of the top plate 14 and the under plate 15, and also, the magnetizing direction of the magnet 13 is set in a radial direction. Since two different magnetic paths via the magnet 13, the top plate 14, and the under plate 15 are formed as the magnetic path, it is possible to apply braking to the voice coil 17 moving outside the magnetic gap between the center pole 12 and the magnet 13 in large amplitude by two magnetic circuits and to prevent distortion due to the asymmetric property of a driving force in the large amplitude from occurring.
