Title: Motor controller of digital disk player
Inventor: NISHIKAWA AKINARI
IPC: H02P29/00
Filed: 1982-06-15
Abstract: PURPOSE:To control accurately the revolving speed of a motor although it is impossible to extract the synchronizing signal of a digital data signal, by controlling the revolving speed of the motor on the basis of the comparison between the maximum or minimum inverting interval of the digital data signal and the standard value. CONSTITUTION:A recording signal processing circuit 13 extracts only the digital data signal component out of the signal read out of a disk 11. A maximum interting period detecting circuit 14 detects the maximum inverting period of the digital data signal supplied from the circuit 13 by means of the reference signal given from a reference signal genrating circuit 15 and then delivers the result of detection as a comparison signal. A motor control circuit 16 delivers the voltage signal corresponding to the comparison signal of the circuit 14 and applies it to a revolution driving motor 17 of a disk 12. Thus the winding driving current of the motor 17 is controlled, and the motor 17 is controlled so that its revolving speed is substantially constant for the maximum inverting period on the basis of the comparison output of the circuit 14.

Abstract: PURPOSE:To prevent key input failure by defining the end of an interlocking rod that slides on a sliding surface as a straight line extended in a longitudinal direction of the interlocking rod, and by defining the length of the straight line in such a way that it is connected to the entire sliding surface, at least in the range that the interlocking rod regulated through a regulating surface is moved. CONSTITUTION:The end of an interlocking rod 2 that slides on a sliding surface 3a is defined as a straight line 2a extended in a longitudinal direction of the interlocking rod 2, and its straight tine 2a has the length that is connected to the entire sliding surface 3a, at least in the range that the interlocking rod 2 regulated by regulating surfaces 3b-3d is moved. Since the straight line 2a of the interlocking rod 2 is line-connected with the sliding surface 3a, the angular part of a bent and folded part 2c of the straight line 2a will not be point- connected with the sliding surface 3a, and the abrasion on the sliding surface 3a is reduced, while concentration of a load into the sliding surface 3a can be avoided, and there will be no case where a push-down stroke is not obtained. Key input failure can thus be prevented.

Abstract: PURPOSE:To improve image quality in a device onto which an image producing unit and a printer unit can be selectively loaded by stopping the operation of the printer unit if the temperature of an electrophotographic fixing part exceeds the fusing point of ink when the printer unit is loaded instead. CONSTITUTION:A photosensitive body, an electrostatic charger, a developing device and a cleaner are united in the image producing unit 2, while a heat sensitive head, an ink ribbon roller, a take-up roll, etc., are united in the printer unit 22.

Abstract: PURPOSE:To improve heat insulating properties against sun light, by combining a hollow circular corn and a circular corn in the heat flowing direction from a heat dissipating surface to the outer space and changing the interval between both the corns by driving a bimetal. CONSTITUTION:The driving force of rotation of a bimetal 2 actuated by the temperature of a dissipating surface is changed to linear motion by a gear 7. When the temperature of the dissipating surface 1 rises and dissipated to the outer space, a rod 8 is moved to the outer space side and the interval between the hollow circular corn 9 and the circular corn 10 is expanded, so that the quantity of dissipation is increased. When the temperature of the dissipating surface 1 falls and heat is insulated to the outer space, the rod 8 is moved to the body side of an artifitial satellite and the circular corn 10 comes into contact with the hollow circular corn 9 to insulate the dissipating surface 1 from the outer space. Since the rod 8 is formed like a taper and the hollow circular corn 9 and the circular corn 10 are made of thin plates having specular aluminium surfaces, so that the independence of direction to the sunbeams is improved by adopting these circular corn shapes.

Abstract: PURPOSE:To enable to easily prepare the layout of the circumference of a bonding pad by a method wherein a part of a resistor is formed as a part of the source or drain region of MISFET, thereby enabling to reduce the occupation area of said resistor and to improve the degree of integration. CONSTITUTION:A resistor R2 is formed in such a manner that a part of which will be used as a part 14 of the P<+> type drain region 11 of the P-MIS Q5 on an output part. To be more precise, said resistor R2 consists of the part 14 of the P<+> type drain region 11 and a P<+> type region 15. Said P<+> type region 15 is connected to the N-MIS Q2 of the input part 5 and the gate electrode of a P- MIS Q3. Oblique lines are drawn on the region which functions as the resistor R2. The gate electrode of Q5, wherein a part 14 of the drain region 11 is used as a part of the resistor R2, is therefore formed in bent form, not in a straight line as in the gate electrode of Q4. The drain region 11, located on the part where the drain region 11 and an aluminum wiring 18 are contacted, is formed width, whereas the drain region on the region 14 is formed narrower in width. The resistance value of the region 14 can be increased by narrowering the width of the region 14.
