Title: Current mirror circuit
Inventor: YAMASE SHINYA
IPC: G05F3/24
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To supply constant currents which have nearly the same current values to a 1st and a 2nd MOS transistor(TR) and operating them properly as a current mirror even when a MOS TR which has deteriorated in saturation characteristics is used by providing a potential difference generating element which is connected between a 2nd and a 3rd drain or source and generates a potential difference between them. SOLUTION: When the TR having deteriorated in saturation characteristics is used, constant currents flowing to the 1st and 2nd MOS TRs TR1 and TR2 are different and they often do not operate as a current mirror. A 2nd resistance R12, however, is connected between the drains of the 2nd and 3rd MOS TRs TR2 and TR3 and then the potential of the drain of the 2nd MOS TR TR2 normally rises to make it possible to set the drain-source voltage of the 2nd MOS TR TR2 almost equal to that of the 2nd TR TR1.

Title: Carbon dioxide sensor
Inventor: MATSUDA YOSHIO
IPC: G01N27/416
Filed: 1988-10-07
Abstract: PURPOSE:To enable the realization of a small and inexpensive sensor by measuring the concentration of carbon dioxide to be inspected using an Na<+> conducting solid electrolyte by a direct interpolation formula to secure a high accuracy and a high stability. CONSTITUTION:An electrically insulating material 1 is a tubular body with both ends thereof opened and a heating element 6 is arranged on an outer surface thereof while an anode electrode 4 on the inner surface thereof. A block of an Na<+> conducting solid electrolyte is inserted into a hollow part of the insulating material so as not to contact the inner surface thereof directly. The electrolyte 2 has a cathode electrode 3 formed at one end 2b thereof and a layer 5 of Na2CO3 is provided to bridge between the other end thereof and the electrode 4. When a gas to be inspected having carbon dioxide contacts this sensor, an electromotive force is generated between the electrodes 3 and 4 in proportion to the concentration of the carbon dioxide (partial pressure). If a relationship between the gas and the electromotive force is prepared by a calibration curve, the concentration of carbon dioxide in the gas to be inspected can be learned from the electromotive force when the sensor is inserted into the gas to be inspected. Thus, the electrolyte 2 and the electrode 4 are so arranged as not to contact each other directly, thereby achieving a higher accuracy and stability.

Title: System stabilizing device
Inventor: TAGUCHI YASUHIRO
IPC: H02J3/24
Filed: 1989-09-29
Abstract: PURPOSE:To restrain the acceleration of a rotor without any control resistor of a large capacity by a method wherein a means, effecting stabilizing control by intercepting a pump upon serious trouble, is added to a system stabilizing device, stabilizing by throwing a brake resistance. CONSTITUTION:The degree of trouble is operated by a trouble condition discrimi nating circuit 8 in a system stabilizing device 3. When the trouble is judged by a control circuit 9 that it is serious, the system stabilizing device 3 transmits a pump-up intercepting signal 16 different from a brake resistance throwing signal 10. According to this method, strong system stabilizing control may be effected. In this case, the throwing of the control resistance prevents the acceleration of the rotor of an accelerating side generator while the pump-up interception prevents the deceleration of a system side generator. The brake resistance of a large capacity is made unnecessary by adding the stabilizing control, effected by the pump-up interception, to a system stabilizing device 3 so far. Further, the acceleration of the rotor may be prevented considering the balance between the demand and supply of the side of the system.

The swinging scroll 30 is not pressed against a fixed scroll 33, and gas seal performance and compression efficiency in a scroll compression element 23 are improved, and both the fixed scroll 33 and the swinging scroll 30 can be made of aluminium.
