Title: Infrared gas analyzer
Inventor: TANIGUCHI HARUTAKA
IPC: G01N21/61
Filed: 1986-04-18
Abstract: PURPOSE:To easily prevent a measurement error from occurring by making an infrared ray incident on a measurement cell into parallel luminous flux and also providing a light scattering body between the measurement cell and a detection chamber. CONSTITUTION:The infrared ray from a light source 3 becomes measurement light Im parallel to a tube body 7 through an infrared lens 25. The 1st transmitted light 101 transmitted through the measurement cell 5 is incident on a plate-shaped body 26 while it is still the parallel luminous flux. The plate-shaped body 26 is translucent, so the light 101 is scattered and then the light 101 which enters the 1st detection chamber 16 through the plate-shaped body 26 is in a scattered state. Part of it enters the 2nd detection chamber 17 as it is, but the remainder is reflected by the internal wall of the detection chamber 16 and then enters the detection chamber 17 as the 2nd transmitted light 102. The light 102 is also reflected by the internal wall of the 2nd detection chamber 17 and then transmitted through a window 100. Thus, the light 101 and the light 102 are scattered in the detection chamber 20, so the mean optical path lengths of those light beams become shorter than the lengths l1 and l2 of the detection chambers. For the purpose, the thickness Q of the plate-shaped body 26 is varied to specific thickness to remove an interference error caused by the vapor of chimney discharge gas 12.

Title: Control/diagnosis system with microprocessor as base for motor operated valve
Inventor: BOIDO PII BURUTSUKUSU
IPC: G05B19/35
Filed: 1988-04-12
Abstract: PURPOSE: To remarkably reduce the problems of the overshoot of a valve by detecting the location of a valve stem and periodically calculating the location of the valve stem when a motor is turned off from the present location by a computer. CONSTITUTION: The location of a valve stem 400 is detected by a multi-turn winding potentiometer 46 via a gear 108. The load of the valve stem 400 is detected by an SPD potentiometer load sensor 48 via a spring pack. Further, actual motor load is measured for the overheat load protection of a motor. These measured values are processed at the period of 50 times/second, for instance, by using a microprocessor. By this constitution, the location and the valve stem and the load of the valve stem are predicted, and when either one of them exceeds an expected correspondence point, the motor is switched to be turned off and the adverse effect of the overshoot due to the inertia of rotational is effectively prevented.

Abstract: PURPOSE:To increase the processing speed and to enable a user to intervene in the translation processing process by finding translated candidates of an inputted syntactic unit, determining one of translated candidates and transforming this candidate to a form according with grammar of the natural language. CONSTITUTION:If a translating instruction is issued from the user at the time of inputting an arbitrary syntactic unit from an input device 11, a translated candidate retrieving device 12 finds translated candidates of the syntactic unit. A translated word determining device 13 determines one translated word from these candidates. Thereafter, this translated word is transformed to a proper form by a transforming device 14. If a retranslating instruction is issued from the user at this time, another translated candidate is selected by the translated word determining device 13 and the processing is performed again. The control is returned to the start of the processing if input is continued, but otherwise, the processing is terminated.
