Title: Injection unit turning device for injection molding machine
Inventor: MIYAUCHI TAKAKI
IPC: B29C45/20
Filed: 1995-06-27
Abstract: PURPOSE: To make an injection unit turn sufficiently even with a cylinder of stroke at the time of nozzle touching by providing two connecting holes for nozzle touching and turning at a joint which connects a nozzle touch cylinder and the injection unit. CONSTITUTION: Turning center holes 17 and 18 of a sliding stage and an injection unit 6 are made to coincide with each other so as to insert a turning pin 19 into them and a guide block is removed. A connecting pin which connects the injection unit 6 to a nozzle touching connecting hole of a joint 30 at a tip of a piston rod 20a is pulled out. The piston rod 20a is moved to a nozzle touch position by a stroke L and stopped at a position where a connecting hole for turning of the joint 30 and a connecting hole of the injection unit 6 coincide with each other so as to insert the connecting pin which is pulled out previously. When a nozzle touch cylinder 20 is operated, the joint 30 moves by a stroke L+S and the injection unit 6 turns with supporting point at the turning pin 19 as shown by a chained line 6a. Returning of the turning is performed in a reversed process.

Title: Method for processing optical fiber gyro signal
Inventor: WASHIMI KOICHI
IPC: G01C19/72
Filed: 1991-06-27
Abstract: PURPOSE:To reduce errors in measurement due to decrease in the quantity of light by detecting the drop of the output of even higher harmonics below a fixed value so as to detect a drop in the quantity of light reaching a light- receiving element, and then giving warning. CONSTITUTION:Light emitted from a light-emitting element 1 is divided into two rays of light by a light bifurcating element 2 and incident on both ends A, B of optical fiber 5 through respective lenses 3,4. The counterclockwise and clockwise rays of light are both allowed to pass through a sensor coil 6 and that portion 8 of the optical fiber which is wound on a phase modulating element 7 and are synthesized with each other at the light bifurcating element 2 and incident on a light-receiving element 9. Decreases in the quantity of light reaching the light-receiving element 9 are detected by monitoring the output of quadruple harmonics or other even harmonics. When the quantity of light reaching the light-receiving element 9 decreases warning 19 is given to urge the replacement or repair of an optical fiber gyro; or, tan<-1> correction is switched to sin<-1> correction. Accurate results of measurement of angular velocities can thus be obtained even if the quantity of light reaching the light-receiving element 9 decreases.
