Title: Apparatus and method of detecting object about vehicle
Inventor: HANAWA KAZUHIKO
IPC: B60R21/34
Filed: 1994-02-22
Abstract: PURPOSE:To prevent collision with an obstacle by detecting a distance to the obstacle and the direction on the rear side of a vehicle and the results are displayed being superimposed on own vehicle with an onboard display to allow an operator to recognize a positional relationship between the own vehicle and the obstacle. CONSTITUTION:The distance to and direction of obstacles 5 and 6 existing on the rear side of an own vehicle 3 are detected with a radar 1 and the outline of the obstacles is displayed with an onboard display 2 being superimposed on the outline of the own vehicle 3.

Title: Pressure sensor
Inventor: KAWANO ATSUSHI
IPC: G01M3/26
Filed: 1987-02-05
Abstract: PURPOSE:To improve the safety of an opening/closing mechanism with a simple constitution by providing a pressure generation space for air tube inspection which interrupts outside air by the stroke of a valve body and increases the pressure in the inside space of an air tube through a communication hole. CONSTITUTION:The pressure generation space 23 for air tube inspection which is interrupted by the valve body 18 from the outside air and communicates with the inside space of the air tube 6 through the communication hole 10 is provided in the vicinity of the communication hole 22 where the valve body 18 has a stroke. When the valve body 18 has the stroke in the space 23, the hole 22 interrupts the outside air and the pressure in the inside space of the tube 6 increases and is detected by a pressure sensing element 13. If the air tube damages, the pressure in the inside space of the tube 6 does not varies and the pressure detection is therefore not performed. While the valve body 18 does not closes the hole 22, the space 23 communicates with the outside air. Consequently, the safety of the opening/closing mechanism is improved with the simple constitution.
