Title: Driving method of air cleaner for vehicle
Inventor: KOIZUMI SHINJI
IPC: B01D46/46
Filed: 1991-01-31
Abstract: PURPOSE:To improve the driving method of an air cleaner for a vehicle, based on the fact that conventional air cleaner can not completely attain its object, because it starts cleaning when air pollution starts. CONSTITUTION:An air cleaner 1 for a vehicle is started by an operation prior to smoking such as the firing of a lighter, that is, the switch SW of the air cleaner 1 is turned on by a non- visible beam sensor 2 to start air cleaning before the air is polluted. In addition, the air cleaner 1 is turned off by a timer 3, which hold the switch SW turned on for the specified time after the completion of detection by the non- visible beam sensor 2 mentioned above. This driving method reduces the generation of pollution, improving the environment in the vehicle room.

Filed: 1989-02-14
Abstract: PURPOSE:To prevent unnecessary operation of circuit breakers by switching the operational sensitivity of a current differential relay to a low level for a predetermined period of time on the condition of occurrence of closing command for the circuit breaker at its end. CONSTITUTION:A current differential relay 3A takes in the voltage at terminal A from a line 5A, then an input processing section 6A samples the voltage simultaneously with current taken through a current transformer 2A thereafter the voltage and the current are subjected to A/D conversion. Operating section 7A in the current differential relay 3A performs sensitivity switching operation of the current differential relay 3A based on a circuit breaker closing command. The sensitivity switching operation is carried out by means of AND gates 18, 22 and a NOT gate 21 so that a high sensitivity current differential relay 15A is switched to a low sensitivity current differential relay 16A thus tripping the circuit breaker through AND operation with a current compensation undervoltage relay 13A. By such arrangement, unnecessary function of circuit breaker can be prevented reliable until the current compensation undervoltage relay 13A is reset.

Filed: 1978-03-23
Abstract: PURPOSE: To enable a person, who has his lens adjusting ability deteriorated, to enjoy a comfortable field of view continuously from a long range to a short range by forming the upper region of the eyeglass lens above the vertical intersection of the main meridian in a manner to have the same curvature as that of the intersection and by using the plane in the vicinity of and along the round intersection as a nable.  
     CONSTITUTION: An eyeglass lens is vertically divided by the intersecting point A between a main meridian MM' and a round intersection. The intersection group has its curvature decreased the more in the lower region as it leaves the meridian MM' the more but held identical to the intersecting point in the upper region. The plane along and in the vicinity of the round intersection is in the form of a nable. The intersection between the plane intersecting with the meridian MM' and a refraction plane is located above the upper end of a progressively focusing portion P so that a wide field of view can be obtained from the progressive focal point to the short range portion N. At the progressively focusing portion P and the short range portion N, the curvature of the intersection group becomes the smaller as it leaves the meridian MM' the more so that the astigmatism and distorsion can be minimized even in the vicinity of the portions P and N. The nable-shaped curve along the round intersection can provide a comfortable feeling for the transverse movement of the eyes in the long range portion.
