Title: Mass flowmeter
Inventor: IKEDA KIYOUICHI
IPC: G01F1/84
Filed: 1982-04-30
Abstract: PURPOSE:To obtain a mass flowmeter having a simple constitution and a low electric power consumption, by constituting a pipe line so that its specific natural frequency is regulated within a frequency zone of the fluid noise to vibrate the pipe line by utilizing resonance of the pipe line due to fluid noises in a Coriolis flowmeter. CONSTITUTION:Fluid noise of a high restriction type white noise is generated, when a fluid is flowed in a pipe line 1. The pipe line amplifies the fluid noise selectively to vibrate by a Q of the pipe line itself (usually 500-1,000 in a primary mode) in each natural frequency. The Coriolis' force is acted to the pipe line 1 corresponding to the vibration in each natural frequency and the vibration of a Coriolis vibration mode is generated in each natural frequency. Outputs e1, e2 of vibration detectors 61, 62 at this time is turned to the output corresponding to the natural frequency of the primary mode. Thus a mass flowrate output e0 is obtained by finding its phase difference in an arithmetic circuit 7.

Title: Ultrasonic slant flaw detection
Inventor: ANDOU NOBUYUKI
IPC: G01N29/04
Filed: 1979-06-13
Abstract: PURPOSE: To expand the flaw detectable range for a cylindrical test material by specifying the arrangement of the probe.  
     CONSTITUTION: Ultrasonic wave transmitting elements T 1  and T 2  and receiving elements R 1  and R 2  are so arranged that the transmitting element T 1  and receiving element R 1 , the transmitting element T 2  and receiving element R 1 , the transmitting element T 2  and receiving element R 2  and the transmitting element T 1  and the receiving element T 2  are positioned at two corresponding bottom angles of isosceles triangles with the testing point K of the cylindrical test material P as the apex. This allows the ultrasonic wave to turn to the testing point K on the center line l of the welding bend WB in the transmission and receiving direction so that it reaches the welding bead WB not at the right angle to the extention of the bead. Therefore, the flaw detectable limits each due to the ratio of the thickness to the outerdiameter, the excess padding height and the ultrasonic wave channel can be extended without changing its sensitivity characteristic to artificial defects of the probe having a normal refraction angle.

Abstract: PURPOSE:To prevent the racing of an engine, the burning of a clutch in an automatic transmission and the like by temporarily raising an idling speed over a normal running speed range when the automatic transmission is selected from a neutral range to a travel range. CONSTITUTION:An electronic control device 16 makes judgement as to whether a signal from a select switch 17 is changed from a non-travel range (P and N ranges) to a travel range (D, R and L ranges), on the basis of signals from a throttle valve switch 15 and a vehicle speed sensor 19 when a throttle valve is totally close and the vehicle speed is equal to the predetermined value or less. Upon judgement of the signal change, the control device 16 sends an instruction so that an idling speed becomes A (e.g. 750 r.p.m.) only during a time (t) (e.g. 1 second). After the elapse of the time (t), the instruction is changed for keeping the idling speed at B (e.g. 650 r.p.m.). According to the aforesaid construction, the delivery capacity of an oil pump for an automatic transmission 12 immediately after gear selection is properly maintained and a clutch is quickly engaged, thereby ensuring quickly a travel ready state.
