Title: Angular velocity sensor and image pickup system employing it
Inventor: OGINO SHIGERU
IPC: G01C19/5656
Filed: 1993-09-24
Abstract: PURPOSE:To detect angular velocity for two axes simultaneously with high accuracy using one sensor by employing a beam for detecting vibration having one fixed end and the other rotatable end. CONSTITUTION:The sensor comprise an elastic square prism 1 having a piezo-electric element and an electrode stuck on its side faces and its bottom face is fixed. Driving piezo-electric elements 11x, 11y are driven by a sine wave voltage of predetermined frequency obtained by shifting the phase of a driving signal delivered from an oscillation circuit 13 by 90 deg.C through a phase shift circuit 14. In other words, the free end of the square prism 1 rotates at an angular velocity omegaz around Z axis. When the square prism 1 is turned by OMEGAx in X axis direction, Coriolis force is generated. Assuming the vector of Coriolis force is F, the vibratory speed vector is V, and the angular velocity vector is OMEGA, F=2mVXOMEGA is satisfied and since a formula of flexureproportional F is satisfied, ¦OMEGA¦ can be determined. Output signal from a piezo-electric element 12x is amplified 15 and the frequency components deviating from the detection band of the sensor are removed through a BPF 16. Driving signal for the piezo-electric element 11x is then subjected to phase shift 14, synchronous detection 17 and smoothing thus producing an output Vx.

Title: Ribbon oscillator
Inventor: MAEKAWA TOMOHIRO
IPC: B41J35/14
Filed: 1986-10-08
Abstract: PURPOSE:To detect an oscillating position without being affected by defective mounting of a ribbon frame, by providing a sensor for detecting the presence of an ink ribbon, a means for discriminating whether an ink ribbon has reached a stopping position, or not and a controlling means for stopping a motor when the ink ribbon has reached the stopping position. CONSTITUTION:A sensor 6 is constituted of a light source, a light-receiving element and a slit. When a ribbon cassette 1 is disposed in a printing position, the light-receiving element is shielded by a ribbon, so that it does not operate, namely, the sensor 6 is in an 'OFF' position. When the ribbon cassette 1 is oscillated, the light-receiving element receives light, and the sensor 1 is turned 'ON'. When the sensor 6 is in an 'ON' state, a pulse motor 5 is reversely totated by one step in the direction for lowering the lower end 1a of the ribbon, and it is discriminated whether the sensor 6 is 'ON' or not. When the sensor 6 is 'ON', the motor 6 is rotated until the sensor 6 is turned 'OFF', and a counter P for rotating quantity of the pulse motor is reset to the initial value '0', thereby completing setting of a reference position of the ribbon cassette 1. Thus, a printing part of the ribbon may be accurately set to a desired position.
