Title: Object detection device
Inventor: SAKAGAMI OSAMU
IPC: G01V8/10
Filed: 1995-10-03
Abstract: PROBLEM TO BE SOLVED: To judge whether an object exists or not without being affected by disturbance light even if the disturbance light is much by providing, for example, a judging means for judging whether the intensity of the disturbance light, which a light reception element receives when the element is turned off, is equal to or more than a specified value or not. SOLUTION: A means is provided to judge whether disturbance light which a light reception element 12 receives when a light emitting element 11 is turned off is equal to or more than a specific value or not. Namely, when the light emitting element 11 is turned off and a voltage V0 is equal to or more than a specified value, it is judged that 'Tape (object to be detected) exists. Namely, the tape surface reflects, for example, solar light and emits disturbance light, and the disturbance light reaches the light reception element 12, the voltage V0 increases over the specified value. On the other hand, when the voltage V0 is less than the specified value, the light emitting element 11 is turned on to judge to see if the voltage V0 is equal to or more than the specified value or not. When the voltage is equal to or more than the specified value, it is judged that 'No tape exists'.  Namely, since no tape exists, light emitted by the light emitting element 11 reaches the light reception element 12 and the voltage V0 increases over the specified value.

Title: Method of detecting contact pressure of shear type slitter
Inventor: IKEDA NORIAKI
IPC: G01L5/00
Filed: 1987-10-12
Abstract: PURPOSE: To detect the contact pressure between a top slitter and a bottom slitter quantitatively and precisely by interposing a strain detection member adapted to strain in dependence on the contact pressure between both these slitters, between the top slitter and a housing. CONSTITUTION: Papermaking slitting work is allowed by pressing a top slitter 3 down on a bottom slitter 2 rotating. The reaction force or contact pressure of the bottom slitter 2 relative to the top slitter 3 during this process accordingly strains a strain detection member 22 interposed between the top slitter 3 and a housing 4. When a contact pressure is caused between both these slitters 2 and 3, the position of the strain detection member 22 relative to the housing 4 is held unchanged but that relative to the top slitter 3 changes because of the free axial movement of the top slitter 3. By this principle the strain detection member 22 is allowed to have a distortion, which is detected by a strain gauge 29 and is used for the calculation of the contact pressure between both these slitters 2 and 3.
