| 20090173551 | Support Structure of Mass Sensor Used in Scales - The present invention protects a mass sensor from an overload in any direction. A support structure is accommodated in a case, has a floating frame provided on one end side and a fixed portion provided on the other end side, receives a load of an object to be weighed placed on a scale pan with the aid of the floating frame part, and supports the mass sensor used in scales to detect the mass of the object to be weighed. The support structure has a spring member for supporting the mass sensor, and is interposed between the fixed portion and the case, which are structural members. The spring member is elastically deformed in advance to thereby press/urge on the fixed portion of the mass sensor and cause the portion to come into contact with the structural member side. The spring member deforms elastically so that the fixed portion separates from the contact location when a force greater than the pressing/urging force is applied. | 07-09-2009 |
| 20090100919 | Engine Measurement Device - An engine measurement device includes a detector for measuring individual pieces of time series data containing at least a speed and output torque of an engine in a transient state while the engine is being run in combustion by control of an engine control unit, a torque operation unit for calculating the engine torque on the basis of the time series data of the engine speed and the output torque, and a model operation unit for modeling the engine torque as functions of the engine speed and a fuel injection time. This model is used to calculate both a fuel torque generated by the combustion run of the engine and a mechanical loss torque or the difference between the engine torque and the fuel torque. | 04-23-2009 |
