Abstract:
The disclosed motor control circuit includes a speed loop controlling the rotational speed of the rotor of a motor. A phase control loop controls the rotational phase of the rotor, and a voltage control loop controls a voltage applied to a winding of the motor according to the current flow through the winding. The voltage control loops maintains the rotational speed and rotational phase constant despite variations in the load torque. The control circuit is especially well-suited for motors having a small torque.
Abstract:
Provided is a natural leather having a novel coating layer which feels leathery. The coating film retains material properties such as strength and wearing resistance. When the user directly touches the natural leather, the coating layer present on the surface of the natural leather gives slick characteristics of natural leathers and smoothness. The natural leather has a coating film formed on a surface thereof, the coating film including: a color coat layer formed from a mixture of a hard component (10% modulus is more than 2.3 but no more than 3.0) and a soft component (10% modulus is more than 0.0 but no more than 1.0) of a two-component polyurethane resin; and a topcoat layer formed from a mixture of a medium component (resin having a 10% modulus of more than 1.0 but no more than 2.3) and a soft component (resin having a 10% modulus of more than 0.0 but no more than 1.0) of a two-component polyurethane resin.

Abstract:
An object of this invention is to provide a printhead tolerant of switching noise occurred when concurrently driving plural printing elements, a head cartridge using the printhead, and a printing apparatus. To achieve this object, a printhead includes plural printing elements and plural driving elements for driving the plural printing elements, and prints by these printing elements. The printhead includes the following arrangement. More specifically, the printhead includes a shift register which receives print data in synchronism with a clock signal, and a latch circuit which latches the print data input to the shift register in synchronism with a latch signal. The printhead further includes a restriction circuit which restricts input of the print data and clock signal to the shift register and input of the latch signal to the latch circuit in synchronism with input of an enable signal for driving the plural driving elements.
