Title: Valve for internal-combustion engine
Inventor: ERUNSUTO HORUMAA
IPC: F01L3/20
Filed: 1989-11-14
Abstract: PURPOSE: To enable a valve to be relatively light in weight even when the diameter of a valve head is large by providing an abutment surface on a valve stem for abutment with a fixed abutment surface of a valve guide. CONSTITUTION: A collar 16 on which an abutment surface 17 is formed is provided on a valve stem 3 in a valve 1.

Thus, the force applied to a valve head 2 is distributed to abutment surfaces 12, 17, therefore a convex portion 13 of the valve head 2 can be extremely thin. As the thickness of the valve head 2 is smaller, the weight of the entire valve 1 can be lighter. Consequently, the force necessary for opening and closing the valve applied to the valve mechanism can be smaller.

Filed: 1990-11-01
Abstract: PURPOSE:To rapidly render the output of a toner sensor to a steady state, control the toner density, and improve the image quality by rotating a stirring rotor faster than as usual in restarting image formation after a relatively long stopping time. CONSTITUTION:When a copying machine is redriven through a relatively long time A after once stopped, a stirring rotor 21 is rotated at a speed V2 upper by 20-30% than the speed V1 at the time of general copying about for several seconds from this point of time, and then the speed is returned to the speed V1. According such a driving system, the excessive time until the detection output of a toner sensor 24 abnormally increased at the time of redrive is returned back to the steady state can be set to about several seconds. Namely, the excessive time can be highly shortened, compared with the case in which the rotation of the rotor 21 is regularly fixed. Almost immediately after the redrive, the output of the sensor 24 can be read in a CPU 20 to control the toner density.

Title: Nitrogen oxide sensor
Inventor: ONO TAKASHI
IPC: G01N27/416
Filed: 1997-10-15
Abstract: PROBLEM TO BE SOLVED: To inexpensively and accurately detect NOx concentration in measurement atmosphere by allowing first and second electrodes to detect mutually converted NO and NO2 simultaneously and measuring the potential difference between both electrodes. SOLUTION: A detection target atmosphere gas flows into canned rooms 5 and 6 via a front room diffusion resistor 4 and a nitrogen oxide consisting of NO, NO2 , and nitrogen peroxide sucks or discharges an oxide gas by oxygen pump electrodes 10, 10', 11, and 11'. The NO or NO2 gas that is converted after oxidation or reduction flows into a rear room via a rear room diffusion resistor 9. Nitrogen oxide detection electrodes 1 and 2 respond to NO being converted by an oxygen pump with one electrode and NO2 being converted similarly with the other electrode since a potential change based on the concentration of NO and NO2 is opposite.  Therefore, a potential difference based on NO or NO2 concentration being generated between the nitrogen oxide detection electrodes 1 and 2 increases due to synergistic effect, thus remarkably increasing a detection signal and hence improving detection accuracy.
