Title: Semiconductor acceleration detector
Inventor: YAMAMOTO MASAHIRO
IPC: H01L29/84
Filed: 1992-04-28
Abstract: PURPOSE:To improve the electric characteristics of a semiconductor acceleration detector and to improve the adhesive property of a wire and a pad. CONSTITUTION:A semiconductor acceleration detector has a base 2, a stage seat 3, which is fixed to the base 2, an acceleration detecting beam 1, whose one end is supported with the stage seat 3, and a weight 4, which is mounted on the other end of the acceleration detecting beam 1. The semiconductor acceleration detector also has a pad 7 for outputting the electric signal, which is obtained by converting applied acceleration with an acceleration detecting region 8, to the outside, wires 6 and lead pins 5. Furthermore, the acceleration detecting beam 1 and the stage seat 3 are fixed with a bonding agent 9. Since the width W1 of the stage seat 3 is narrower than the width L of the acceleration detecting beam 1, the bonding area is small. Since the bonding area of the stage seat 3 and the acceleration detecting beam 1 is small, thermoremanent stress generated in the bonding agent 9 can be made small. The electric characteristics of the semiconductor acceleration detector can be improved.

Title: Measuring device for amount of condensate
Inventor: OKAMOTO MASAKATSU
IPC: G01F1/00
Filed: 1980-08-13
Abstract: PURPOSE:To measure the accurate amt. of condensate with simple construction by such constitution wherein a recess is provided to a condensate pipe connected to a flow rate meter and condensate is discharged from the flow rate meter via a steam trap connected to a pressure equalizer. CONSTITUTION:The steam generated from a steam generator is supplied via a steam supplying pipe 1 to a steam using apparatus 2. Produced condensate flows into a condensate pipe 3 and passes through a flow rate meter 5 via a water sealed recess 4, thence it is discharged from a steam trap 8. Since a pressure equalizer 7 branched from the pipe 1 is communicated with the stream trap 8, the pressure of the pipe 3 on the inlet side of the steam trap is maintained constant. Since the recess 4 of the pipe 3 is sealed by water, the condensate does not reevaporate in the flow rate meter 5 and the recess 4. Hence, the accurate amt. of the condensate is measured with the simple construction.
