Title: Mass flow rate sensor
Inventor: HANSU HEHITO
IPC: G01F1/692
Filed: 1993-06-11
Abstract: PURPOSE: To obtain reproducible flow characteristics on the surface of a measuring chip which protects the measuring chip against mechanical load and contaminating particles by building a measuring chip in a casing having a flow-in channel. CONSTITUTION: A measuring chip 2 is built in a channel 9 of a casing 1. A heating element 5 is arranged on a diaphragm 3 and connected through a conductor line 7 with a bonding pad, then connected through a bonding wire 21 with a switching circuit 14. The circuit 14 controls the heating element 5 by processing signals from a temperature sensor for the heating element 5 and a reference temperature sensor. More specifically, the heating element 5 sustains the temperature of the diaphragm 3 higher than a passing medium, and then the flow rate is measured, based on the heat deprived from the diaphragm 3 by the passing medium.  Since the measuring chip 2 is built in the plane of the channel 9, and the cross-section thereof is constricted on the downstream side, a mass flow is prevented from being accelerated to generate vortexes on the chip 2, resulting in stabilized flow characteristics where noise is suppressed, while preventing adhesion of the contaminating particles.

Inventor: NISHISAKA SHIYOUJI
IPC: E21B7/00
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To reduce the turning radius of an excavating device. SOLUTION: This excavating-device elevating mechanism comprises a leader 5 mounted on a from bracket 2 projected from the front of a turning table 12, sprockets 73, 74 provided respectively at the upper and lower ends of the leader 5, and a chain 8 extended endlessly via a drive sprocket 42 and to be connected to an excavating device 9, the drive sprocket 42 being linked to a hydraulic motor 4. In this case, the hydraulic motor 4 and the drive sprocket 42 are located above the front sprocket 2. Since the drive sprocket 42 does not need to be stored in the leader 5, the longitudinal length of the leader 5 can be reduced accordingly, and therefore the turning table 12 of the excavating device 9 mounted at the front of the leader 5 in such a way as to be capable of rising and falling can be decreased in its turning radius from the center of rotation.
