Title: Method of controlling operation of brushless dc motor
Inventor: KAWAGUCHI YUJI
IPC: H02P6/17
Filed: 1987-03-20
Abstract: PURPOSE:To effectively use winding energy at the time of commutation as reflux current, by change-over-controlling another semi-conductor switch while a chopper-controlled semi-conductor switch is ON. CONSTITUTION:The upper arm transistors 4a<+>-4c<+> of an inverter section are driven by the signal of a combining circuit 9 for combining commutation signal from a position detecting circuit 7 with chopping signal from a chopping signal generating circuit 8. Lower arm transistors 4a<->-4c<-> are driven directly by the commutation signal of the position detecting circuit 7. If the semi-conductor switches of both arms could be turned OFF at the same time at the time of commutation, the commutation timing of the semi-conductor switches on the lower arm side is delayed till the semi-conductor switches on the upper arm side are turned chopper-ON. As a result, change-over energy is effectively consumed, and the capacity of a power smoothing capacitor can be reduced.

Title: Reset circuit
Inventor: TASHIRO SATORU
IPC: G06F1/00
Filed: 1988-03-16
Abstract: PURPOSE:To secure the normal operation of an internal circuit by providing a means which outputs a detection signal at the time of detecting that the number of times of oscillation of an oscillation signal reaches a prescribed value and generating a second reset signal to be given to the internal circuit based on this detection signal. CONSTITUTION:When a signal RESET inputted to an external reset input terminal 3 goes to the low level at a time t1, an internal circuit 5 is reset. When the signal RESET is switched from the low level to the high level at a time t2, a frequency divider 6 is set to the set state. The frequency divider 6 starts the frequency dividing operation at a time t3 so that the frequency divider 6 overflows at a time t4 when a second oscillation signal X2 reaches stable oscillation. At the time t4, a signal V is switched from the high level to the low level, and an R-S-FF 7 is reset and the output is changed to the high level, and a synchronizing circuit 8 is synchronized with a system clock phi. At a time t5, an internal reset signal RST goes to the high level and the circuit 5 starts the operation with the clock phi as the synchronizing signal. Thus, since the signal RST goes to the high level to reset the circuit after oscillation of the signal X2 is stabilized, the normal operation of the circuit 5 is secured.

Title: Thermal transfer recording method
Inventor: UCHIYAMA KOJI
IPC: B41J2/325
Filed: 1987-03-19
Abstract: PURPOSE:To enable clearness of printing to be increased to several times the conventional clearness, by setting the feed velocity of an ink ribbon to be lower at the time of the first use of the ribbon. CONSTITUTION:A thermal transfer ink ribbon 1 enclosed in a ribbon cassette 12 and capable of being fed is used for desired printing on a recording medium 13. At the time of the first use of the ink ribbon, the feed velocity v1 of the ribbon 1 and the velocity v2 at which the cassette 12 is moved in a printing direction for the recording medium 13 are so set that v1<v2, and at the times of the second and latter uses of the ink ribbon, the velocities v1 and v2 are so set that v1=v2. For example, when the feed velocity of the ribbon at the time of the first use of the ribbon is set to be 1/3 times the velocity of the cassette, the amount of printing which can be performed with high quality by using the ribbon in the condition where the surface of the ribbon is not roughened is increased to three times that in a conventional method. Namely, clear printing free of contamination can be performed at the times of the first to third uses of the ribbon. At the times of the fourth and subsequent uses of the ribbon, a lowering in printed density and an increase in contamination occurs in substantially the same manner as at the times of the fourth and subsequent uses of the ribbon according to the conventional method.
