Title: Sensorless motor drive circuit
Inventor: SHIMAZAKI TSUTOMU
IPC: H02P6/06
Filed: 1996-11-14
Abstract: PROBLEM TO BE SOLVED: To prevent influence by kickback voltage and external disturbance noise produced in a drive coil in a sensorless motor. SOLUTION: A kickback voltage is generated at the point when output transistors 7 to 12 change to OFF from ON, namely when the drive coils 1, 2, 3 change to non-conductive condition from the conductive condition, and the clock pulse for DFF 20, 21, 22 to fetch the outputs of comparators 4, 5, 6 to DFF 20, 21, 22 is generated during the period between the time delayed by the predetermined period from the kickback voltage generating time and the zero-cross point of the drive voltage generated in the drive coils 1, 2, 3. As a result, outputs of DFF 20, 21, 22 not including the influence of kickback voltage and external disturbance noise can be applied to the logic circuit 23 to surely drive and brake the motor.

Title: Mask control circuit for memory
Inventor: AIZAWA RYOICHI
IPC: G06T3/00
Filed: 1987-12-02
Abstract: PURPOSE:To omit a mask area display memory and to realize memory mask control in simple constitution by deciding whether the address of image data is set in a specific area or not to decide a mask area when memory mask processing is carried out. CONSTITUTION:When the image data is written in a memory 1, an address is produced by an address generator 5. This address is sent to a deciding means 3 and compared with an address showing a specific area designated by a mask area designating means 4 for decision whether the image data belongs to the specific area or not. Then the processing contents are decided between the image data on the part belonging to the specific area and that on the part which does not belong to the specific area. Thus it is possible to designate the specific area with a small quantity of data via the means 3 and by using a simple shape like a rectangle, etc., to the specific area.
