Patent JP-H05288196-A (JP)
Title: Air conditioner
Inventor: KINOSHITA KANJIRO
IPC: F04D29/54
Filed: 1992-04-08
Abstract: PURPOSE:To reduce operating noise and improve fan efficiency by fitting a ring member to the outer periphery of the blade rear edge part of a fan, and enlarging the diameter of the inlet end of the ring member so as to provide a specified clearance between the inlet end of the ring member and the opening edge part of a fan guide. CONSTITUTION:Air existing at the peripheral part in a casing is drifted onto the opening 12 side by the action of a fan guide 11 and blown out outward as shown by a streamline A1 in the state of contraction flow. In this case, a blade rear edge part 3a is provided with a ring member 6 so as to eliminate a clearance in the outside of the blade. Blade tip vortex is not therefore generated, and operating noise is reduced. On the other hand, a clearance 10 is formed between the inlet end 6a of the ring member 6 and the opening edge part 11a of the fan guide 11. Contraflow of air flowing into the fan 2 side from the radially outer side through the clearance 10 as shown by a streamline A2 is generated in this clearance 10 by the suction action of air flow flowing in an opening 12 in the state of contraction flow. This contraflow of air is throttled appropriately, straightened and increased in the flow speed, and its drift onto the radially inner side is suppressed so as to improve fan efficiency.

Title: Abnormality detecting method for engine cooling water temperature sensor
Inventor: ASAKURA MASAHIKO
IPC: G01N25/00
Filed: 1985-04-23
Abstract: PURPOSE:To discriminate exactly the abnormality of a water temperature sensor at the time of running of a vehicle by comparing a water temperature measured by a water temperature sensor when operating the rotation of an engine with the maximum and minimum cooling water temperature of the time at a rotational operation prescribed in advance. CONSTITUTION:At the time of the rotational operation of an engine 5, the CPU of a controlling circuit 20, first of all, discriminates whether an engine revolving speed Ne exceeds a prescribed revolving speed N1 or not by a signal from a revolving speed sensor 11. In case of N3>N1, the engine 5 is in the course of a rotational operation, therefore, whether a cooling water temperature TW measured by a water temperature sensor 12 exceeds the highest temperature TMAX or not is decided by a water temperature sensor 12. The highest temperature TMAX is the highest temperature that the cooling water temperature TW of the time of an operation of the engine 5 can reach. In case of TW<=TMAX, whether the cooling water temperature is below the lowest temperature TMIN or not is decided. The lowest temperature TMIN is the lower temperature at which the engine 5 can execute a rotational operation. Also, in case of TW>=TMIN, it is decided that the sensor 12 is normal. On the other hand, if case of TW>TMAX, or TW<TMIN, it is decided that the sensor is abnormal and when the counting time of a time counter has elapsed by a prescribed time, an abnormality alarm is generated.
