Title: Typewheel position controller
Inventor: TANAKA HIDETAKE
IPC: B41J7/96
Filed: 1981-03-31
Abstract: PURPOSE:To achieve a highly reliable position control with a simplified mechanism by converting a signal from a magnetic sensor into a rotary position feed back signal when the sensor detects the passage through a ferromagnetic film provided at a finger section of a type wheel. CONSTITUTION:When the rotary position of a type wheel 1 connected to a pulse motor 4 is controlled with a closed loop, a magnetic film 8 made of a ferromagnetic material is provided at a finger section 2 thereof and is detected with a magnetic sensor 9. The output signal of the sensor 9 is input into a pulsation circuit 7 as a rotary position feed back signal of the type wheel to obtain a position pulse train signal. This allows the formation of a closed loop as shown in the drawing.

Filed: 1978-04-27
Abstract: PURPOSE:To simplify the manufacture process as well as to enhance the accuracy by attaching the metal film to the piezoelectric component partially or totally via the mask and then fusing away the unnecessary parts with the laser beam to secure a fixed form. CONSTITUTION:The raw crystal is cut out by turning it by angle theta centering on the X axis to obtain Z plate 1, which is then polished into a fixed thickness.

In case the laser beam is used, the electrode film is first coated on the entire surface, and then the area corresponding to the blank part of the pattern is fused away with the laser beam. After this, plate 1 is etched at the areas where no film 2 exists through soaking into the mixture solution of HF and NH4F to be formed into a tuning-fork type oscillator. In this case, it causes no problem at all if projection 4 or the rounded corner part 5 may occur at the side face. Then the unnecessary areas of film 2 are removed based on pattern 7 through the scanning by the laser beam.
