Title: Infrared gas analyzer
Inventor: SOTANI TOSHIYUKI
IPC: G01N21/35
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To provide a long-lived, small-sized and maintenance-free gas analyzer capable of effectively suppressing the deterioration of a filament to eliminate the change with the lapse of time of light emitting characteristic of an infrared light source by supplying a pulse current interrupted in a fixed period and having a duty ratio of repeat pulse varied in each period to the infrared light source. SOLUTION: Since this gas analyzer adapts a multiple modulation method for finely repeating ON/OFF, as a voltage for driving an infrared ray 13, and performing the ON/OFF in a period longer than the repeat period, occurrence of a notching phenomenon in a filament 16 constituting the infrared ray 13 can be suppressed. In each period, since the emitting interval is extended just after start, and the interval is thereafter narrowed, or the duty ratio of repeat pulse is set so as to gradually increase, the notching phenomenon or generation of rush current having a bad influence on the life of the filament 16 of the infrared light source can be suppressed.

Title: Apparatus for producing nitrogen/oxygen of ultrahigh purity
Inventor: NAGAMURA TAKASHI
IPC: F25J3/04
Filed: 1992-04-13
Abstract: PURPOSE:To make it easy to produce liquid oxygen of ultrahigh purity by a method wherein oxygen-rich liquid air remaining after removal of nitrogen is taken into a rectifying column and taken out as liquid oxygen and the gas taken out from the top of this rectifying column is taken into a series of rectifying columns in succession. CONSTITUTION:Compressed raw material obtained through compression by a compressor 1 and removal of dust, moisture, CO, CO2, etc., by a unit 2 is cooled by countercurrent indirect heat exchange with product of the plant at a heat exchanger 3; after that, the raw material is taken into the lower part of a first rectifying column 4. Nitrogen gas resulting from the rectification is taken out from the upper part of the rectifying column 4 and, after its condensation by a condenser 8, liquid nitrogen of ultrahigh purity is taken out. On the other hand, oxygen-rich liquid air taken out from the bottom of the rectifying column is, after deducting a portion of it, taken into the condenser 8 and used for the cooling of nitrogen gas and the deducted portion is taken into the upper part of a second rectifying column 5. The rectification there stores liquid oxygen at the bottom, which is heated by a reboiler 5a and turned to oxygen gas. This oxygen gas is fed to a third 6 and a fourth 7 of rectifying columns in succession and eventually obtained as oxygen of ultrahigh purity.

Title: Optical waveguide type modulator and its production
Inventor: KONDO ATSUO
IPC: G02F1/035
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a modulator which is lower in the effective dielectric constant of buffer layers than that of a dense structure by providing a dielectric material with depletion parts. SOLUTION: Signal electrodes 11 and modulation electrodes 12 and 13 are formed along optical waveguides 10a formed on a crystal substrate 10 of this modulator and the buffer layers are formed between the crystal substrate 10 and these signal electrodes 11 and the modulation electrodes 12 and 13. The buffer layers are composed of the dielectric material 21 and the depletion parts 22.  Since the electric lines of force generated from the modulation electrodes 12 and 13 to the optical waveguides 10a penetrate the depletion parts 22 as well, the effective dielectric constant over the entire part of the buffer layers may be obtained from the constitution ratio in the plane direction of the dielectric material 21 and the depletion parts 22, and the effective dielectric constant of the buffer layers containing the depletion parts consisting of air is lower than the dielectric constant of the buffer layers of the dense structure.

Abstract: PURPOSE:To improve the reliability of guaranteed data by providing a flag register showing whether a data memory device is main or auxiliary and controlling write and read of input data in a memory part and a transfer. CONSTITUTION:The flag register 11 outputs whether the data memory device is main or auxiliary. When the register 11 is set to the main, a read and write control part 14 transmits an instruction of write and read to a transfer control part 12 and a data memory part 13 according to instruction given through a signal line 108. The control part 12 accepts the write and read instruction, and writing and reading of data are normally executed. When the register 11 is set to the auxiliary, the control part 14 indicates the memory part 13 to write and read data, and the memory part 13 executes the instructed action and outputs data on a signal line 105. However, since the state on a signal line 101 is zero, the control part 12 will not accept the read action. Accordingly the reliability of the guaranteed data can be improved.
