Title: Safety device for electric switch of car
Inventor: ROBEERU JIYATSUKU ETSUKERU
IPC: E05F15/00
Filed: 1993-07-09
Abstract: PURPOSE: To securely and instantly stop the running of a movable member when there is an obstacle on the closing path of the movable member to be driven in a safety device for an electric window opening for a vehicle. CONSTITUTION: This device includes a mechanical means with a pawl 25 for forming a strong drive link between a drive input member 2 and an output member 22, and the pawl 25 is retained so that it can be engaged to the drive input member 2 or the output member 22 so far as the force transferred by the pawl 25 remains at most at a preset value due to the operation of a prestressed element 31. The system automatically interrupts a kinetic drive chain for driving the movable member in the case when the force exceeds a preset value. By this mechanism, the device becomes practically insensitive to friction, thus preventing the threshold of the operation stating force from becoming uncertain.

A CO concentration regulator 38 determines a second air-fuel ratio m2 based on a deviation between measurement of CO concentration and a desired set vale. A set air-fuel ratio computer 40 decides a weighted factor alpha in response to a fuel flow rate (v) and a pressure (p) in a furnace measured by a furnace pressure gauge 42, and calculates a set air-fuel ratio ms from the first air-fuel ratio m1 and the second air-fuel ratio m2. A necessary combustion air amount ms A0 is calculated by multiplying the theoretical air-fuel ratio A0 by the set air-fuel ratio ms. The necessary combustion air amount ms A0 is inputted to an air flow rate regulator 44 and is measured by an air flow meter 48 to feed it to a burner 22.

Title: Method for detecting clogging
Inventor: IMAMURA TAKESHI
IPC: F17D5/00
Filed: 1995-06-12
Abstract: PURPOSE: To detect clogging of a channel even when a state of the channel changes, by obtaining in time series a resistance value of the channel which is a divided value of an application pressure of a fluid by a flow rate of the fluid, setting the resistance value at a fixed time point as a reference value, and comparing an increase of the obtained resistance value from the reference value with a threshold value. CONSTITUTION: A control device 11 sets a threshold resistance value which is a half of resistance increase occurring when one of three nozzles is completely clogged, and reads driving data, e.g. pressures of a slurry at an entrance and an exit of a pump 1, a manipulated variable of the pump 1, etc. Then, the control device smooths the resistance value from the pressures at the entrance and exit of the pump 1 and the manipulated variable of the pump 1. The resistance value when a driving state of the equipment becomes first stationary is set as a reference value. An increase of the resistance value measured in time series from the reference value is compared with the threshold value. When the increase exceeds the threshold value, a warning is displayed on a CRT 16.  When the clogging of the nozzle 3 is removed by cleaning or the like, the increase is returned not to be larger than the threshold value, making it possible to detect cloggings afterwards.
