IPC: B01F23/10
Filed: 1980-02-06
Abstract: PURPOSE:To perform purification testing of exhaust gas in the same manner as for the exhaust gas of an actual automobile by mixing the respective component gases constituting a combustion exhaust gas in a manner as to assume predetermined composition by a mixer and introducing these mixed gases into a reactor having a  catalyst. CONSTITUTION:Component gases such as N2, CO, HC, NOx are introduced into a mixer 1 from respective cylinders 131-137 through flow rate regulators 141-142 so as to assume the composition of the exhaust gas of actual automobiles, whereby they are mixed. These mixed gases are introduced into a reactor 16 packed therein  with the catalysts 8 which perform oxidation of CO and HC and reduction of NOx,  whereby the oxidation of CO and HC to CO2 and H2O and the reduction reaction of  NOx to N2 are performed. The treated gases are analyzed in an analyzer 17, and the activity of the catalysts are tested. Thereby, the mixed exhaust gases of the same composition as that of the exhaust gas of actual automobiles are easily obtained and the reactivity of the catalysts is rapidly judged as well.

Title: Humidity sensor
Inventor: KAKINOTE KEIJI
IPC: G01N27/22
Filed: 1982-01-31
Abstract: PURPOSE:To improve the response speed of a humidity sensor, by connecting an air capacitor accommodated in a sealed case filled with dry air interrupted from the atmosphere to an air capacitor opened to the atmosphere in parallel to constitute a closed circuit. CONSTITUTION:The air capacitor 1 interrupted from the atmosphere by the sealed case is connected to the air capacitor 2 opened to the atmosphere in parallel to constitute the closed circuit 3, and to the air capacitors 1, 2, resistors 4, 5 are connected in series and high-frequency voltage 11 is applied. Two poles 7, 8 are insulated through an insulating material 6 and a metallic body 10 having parallel metallic plates 9 as one body is opposed to the other metallic body 10 having the same structure between the two poles 7, 8. Since the capacity of the air capacitor 1 is equal to that of the air capacitor 2 when the humidity in the atmosphere is 0, no signal is outputted from an instrument 12. When humidity is included, the capacity of the capacitor 2 is increased by the difference of dielectric constant between water and air and a signal is immediately generated in the instrument 12, improving the response speed for the measurement of humidity.

Title: Bearing device for motor
Inventor: SHIGA TAKESHI
IPC: H02K5/167
Filed: 1987-01-22
Abstract: PURPOSE:To reduce the starting voltage of a motor when an ambient temperature is low while preventing the vibration of the rotary shaft of the motor when ambient temperature is high, by a constitution wherein a bearing holder is made by a shape memory member, deforms so that the pushing force against a bearing is enhanced when a predetermined temperature has been exceeded but the same force is weakened when the temperature of the member has become lower than the predetermined temperature. CONSTITUTION:When an ambient temperature is low, a holder 21 deforms so as to shorten the free length thereof, therefore, the resilient force or a pushing force against a bearing 20 becomes small in the set length C. As a result, a centrifugal force in a low temperature may be weakened and the starting voltage of a motor in a low temperature may be reduced. On the other hand, when the ambient temperature is high, the free length of the holder 21 is elongated, therefore, the resilient force or the pushing force against the bearing becomes large in the set length C. As a result, the vibration of a rotary shaft 13 may be eliminated.

Title: Weed removing mat and afforestation method
Inventor: WATANABE TETSUEI
IPC: E01H11/00
Filed: 1999-01-22
Abstract: PROBLEM TO BE SOLVED: To easily remove weeds which are in a propagating state and easily execute afforestation works by forming a mat out of a coconut fiber having a prescribed density and a sufficient shading property. SOLUTION: Weeding is carried out from a propagation side of weeds 2 using a coconut fiber mate 1 having a nearly 100% shading property, promoting the extensive propagation of microorganisms and the degradation of dead weeds by shading and air circulation. In this case, weeds 2 under the mat 1 left alone for a prescribed period die, and at the same time seeds of turf 6 are planted on a thin soil layer 5 formed on the mat by sizing. Furthermore, the turfs 6 grow successfully and spread roots, penetrating the mat 1, and weeds 2 on the ground 3 die and biodegrade. Shading prevents weeds form sprouting through the coconut mat 1, and the turf 6 as sodding plants spreads roots over the soil layer 5, preventing weeds brought from other places from growing, thereby treating easily weeds in weed propagation areas and carrying out turfing even in a propagating state.

IPC: F03G7/06
Filed: 1984-01-31
Abstract: PURPOSE:To reduce the dimension of a rotary driving mechaism by installing each inner edge of a spiral-shaped shape memory member and a bias spring onto a rotary shaft and revolving the rotary shaft by the deformation of the shape memory member due to heating and accumulating the turning force onto the bias spring. CONSTITUTION:As for a spiral-shaped shape memory member 23 and a spiral- shaped bias spring 25, each inner edge is installed onto a rotary shaft 19 and each outer edge is installed onto a fixed supporting body 21. When the shape memory member 23 is heated by a line-wire transmission fiber 17, said member 23 develops the force for restoring the memorized shape and revolves the rotary shaft 19 in C direction and stores a turning force by tightening the bias spring 25. When the heating for the above-described member 23 is suspended, said member 23 is cooled, and the shape retaining strength is reduced. Therefore, the bias spring 25 revolves the rotary shaft 19 in D direction by the rewinding force accumulated and the above-described member 23 is rewound. These operations are repeated, and the rotary shaft 19 is revolved in reciprocation.

Abstract: PURPOSE:To relieve the load of the software by providing a changeover means in which the access route is unchanged after and before the changeover with the software of an exchange main body even when a subscriber circuit is changed over into a standby subscriber circuit due to a fault. CONSTITUTION:Suppose that a fault takes place in a #1 subscriber circuit 2, changeover to a standby subscriber circuit 3 and the access route is switched by a means 10. A subscriber connecting to the #1 subscriber circuit is connected to a standby circuit 3 via a subscriber line test terminal 2d. Then a software 5a transfers switching control information of the terminal 2d on a drive point to the circuit 2. That is, it is not necessary to recognize the presence location (scanning/drive point) of the standby circuit 3 when viewed from the software 5a and the changeover means 10 implements the access route switching. Thus, the load of the software is relieved.

Title: Image forming device
Inventor: HANEDA SATORU
IPC: G03G15/16
Filed: 1988-01-27
Abstract: PURPOSE:To prevent deterioration in image quality by providing a means discharging to a photosensitive body with electric charges of polarity identical to the potential of the image background of the photosensitive body, and a means uniformly projecting light of wavelength transmitting toner on the photosensitive body almost at the same time as discharging, after a developing step and before a transfer step. CONSTITUTION:A discharger/exposer 10 is provided between the developing units 4A-4D on an image forming device and a transfer electrode 5. The surface of a photosensitive drum 1 which has been developed and is not yet transferred is electrified with negative ions 41, and a toner 42 electrified negatively adheres thereto. Negative ions 43 whose potential is lower than that of the negative ions 41 owing to the exposure of a laser scanning system 3 remain on the surface below the toner 42. When a light source 14 for the discharger/exposer 10 uniformly projects light on the photoconductive layer surface of the photosensitive drum 1, the potential of the background falls. In case of electric charges below toner overlapping area, the photosensitive body beneath the toner adhering part is exposed when wavelength transmitting the toner is employed for light from the light source 14. Thus, toner scattering is minimized to prevent deterioration in image quality.
