Title: Very low temperature rectifying method for superhigh purity nitrogen
Inventor: HARII CHIYUN
IPC: F25J3/04
Filed: 1990-03-15
Abstract: PURPOSE: To produce ultra high purity nitrogen product without requiring additional energy by condensing superatmospheric nitrogen rich vapor produced through cryogenic rectification of air progressively and rejecting low boiling impurities through revaporization. CONSTITUTION: Compressed supply air 3 is introduced into a cryogenic, rectification plant 4 and separated into nitrogen rich vapor 5 and oxygen rich vapor 6. Nitrogen rich vapor 11 ascends in a heat exchanger 12 and partially condenses gradually to produce nitrogen rich liquid 13 and vapor 14. The former falls down to the bottom of the heat exchanger and stays thereat while the latter rich with low boiling impurities is rejected from the process. The nitrogen rich liquid 13 us passed through a valve 15 and expanded to produce a low pressure fluid 16 which is introduced the shell side of the heat exchanger 12 where the nitrogen rich vapor 11 is partially condensed progressively and nitrogen rich vapor is evaporated. The nitrogen rich vapor 17 is taken out from the heat exchanger and recovered as ultra high purity nitrogen product.

IPC: G05B13/02
Filed: 1996-02-26
Abstract: PURPOSE: To rapidly decide whether or not an adaptive control system is stably operated by a method wherein it is decided from the output of the adaptive parameter regulation mechanism by an adaptive controller to cause coincidence of a fuel injection amount with a target value whether the adaptive controller is stably operated. CONSTITUTION: During operation of an engine, a control unit 34 calculates a fundamental injection amount from the number of revolutions of an engine and an intake air pressure through retrieval of a map, and in a feedback control region, a feedback correction factor is computed based on the output of an LAF sensor 54. In this case, in an adaptive controller having an adaptive parameter regulating mechanism, an adaptive parameter θ hat is calculated so that a deviation between a target value and a control amount is reduced to zero. On a condition that the adaptive control system is situated in an application region, stability of an adaptive control system is discriminated by using the element of the adaptive parameter θ hat, and on a condition that it is not unstable, a correction factor by an adaptive control rule is used as a feedback correction factor.

Filed: 1995-03-23
Abstract: PURPOSE: To reduce a dark current flowing to an externally mounted switch by interposing a reverse flow prevention diode to a non-power supply line side of a pull-up resistor. CONSTITUTION: Reverse flow prevention diodes 64-66 are interposed between switches 53-55 and 2nd pull-up resistors 61-63 in a switch input circuit turned off in the sleep mode and turned on in the wakeup mode by a control circuit. Through the presence of the reverse flow prevention diodes 64-66, it is prevented that a current flowing to the 1st pull-up resistors 56-58 flows to the 2nd pull-up resistors 61-63. Furthermore, the resistance of each of the 2nd pull-up resistors 61-63 is selected to be sufficiently smaller than that of the 1st pull-up resistors 56-58. Thus, the entire circuit is led surely to the sleep state with simple configuration.

Title: Nonaqueous solvent battery
Inventor: SUZUKI SHINTARO
IPC: H01M4/48
Filed: 1986-03-24
Abstract: PURPOSE:To reduce voltage drop in the initial stage of discharge at low temperature by using a positive active material having a specific composition. CONSTITUTION:A positive active material is formed with a mixture of cupric oxide and copper sulfate indicated in CuXS (1.1<=X<=1.9). If copper silfide whose x value is less than 1.1 is mixed to CuO, the voltage drop in the initial stage of discharge is rarely generated, however, the voltage at the start of discharge is very high like 2.4V or more. This high voltage causes the malfunction when the battery is used as a power source of an analog watch. If the value of x exceeds 1.9, the voltage drop in the initial stage of the discharge is remarkably increased, and accuracy of the watch is decreased. The mixing ratio of CuXS is specified to 5-50wt% based on the total of CuO and CuXS.
