Title: Improving method and device for running stability in overrunning state
Inventor: WELSCH KLAUS
IPC: F16D48/02
Filed: 1997-09-01
Abstract: PROBLEM TO BE SOLVED: To improve and secure running stability by disconnecting a frictional clutch when rotational speed is driving wheels is smaller than that of driven wheels, and its difference exceeds a limit value, and connecting the clutch when the difference is a second limit value smaller than the specified first limit value or less. SOLUTION: Difference of rotational speeds between front wheels and rear wheels is compared in respect to both sides of a vehicle. The larger difference is weighted and evaluated according to horiozntal accleration and a gear stage (steps 12, 14, 16, 18). The value renewed by the evaluation is matched correspondingly to a vehicular condition and operation condition. It is compared to a specified limit vlaue in a step 20. When the rotational speed difference exceeds the limit value (step 22), a frictional clutch is opened (step 26). When it is not more than the limit value, the clutch is not controlled (step 24). Rotational speeds of driving wheels and driven wheels are compared to each other in the step 26, and the rotational speed is compensated (step 28). Then, the clutch is closed again (step 32).  It is thus possible to improve running stability in an overrunning state and prevent occurrence under-or over-steering.

Title: Gas sensor
Inventor: SUEMASU TATSUO
IPC: G01N27/41
Filed: 1988-09-20
Abstract: PURPOSE:To directly measure sample gas by providing the mask material reacting with the measurement obstructing factor of a sensor element in a hood. CONSTITUTION:A hood 10 is formed by holding a porous mask material 12 having gas permeability between gold nets 13, 13 having fine pores 13a... and the mask material 12 reacts with the measurement obstructing factor of a sensor element E contained in sample gas to form a stable compound and, by this mechanism, it is prevented that the response of the sensor element E is deteriorated by the measurement obstructing factor. Since the measurement obstructing factor does not react with the sensor element E, the sample gas containing the measurement obstructing factor can be directly measured without applying pretreatment to the sensor element E. Since the response of the sensor element E is not lowered, the life of a gas sensor can be extended.

Title: Developing device
Inventor: TAMAKI SHINJI
IPC: G03G15/09
Filed: 1998-08-21
Abstract: PROBLEM TO BE SOLVED: To suppress a developer from intruding between a sponge seal and a developing sleeve and to stabilize the carrying of the developer at a developing sleeve end part by making the effective magnetizing width of the magnetic pole in a range where a widening preventive member does not exist narrower than that of the magnetic pole in a range where the widening preventive member exists. SOLUTION: A sealing member is stuck to the surface of both side plates 7a of a developer housing case 7 opposed to the developing sleeve. Thus, an interval between the side plate 7a and the surface of the developing sleeve 4 is eliminated so that the movement of the developer to the outside is prevented. The effective magnetizing width of a magnetic pole opposed to an area where the side plate 7a is not provided on the both sides is made narrower than that of the magnetic poles P3 and P4 opposed to a toner taking in part which necessitates the side plate 7a on the both sides at this device. Then, in this case, when for instance the effective magnetizing width of each magnetic pole is changed stepwise under a specified condition, an effect to return a small amount of the developer intruding between the sealing member and the developing sleeve 4 to a center part stepwise is obtained.
