Inventor: SHIMIZU YUKIHARU
IPC: H02K1/18
Filed: 1989-07-27
Abstract: PURPOSE:To avoid extreme dimensional precision for a yoke, a stator, and the like and to lower the cost of a rotating-field type miniature motor as a whole, by providing the section of the yoke contacting the stator with an elastically distortable section. CONSTITUTION:At the central section in a yoke 1 a rotor 2 consisting of a plurality of permanent magnets is rotatably set in a radical direction via a coil frame member 3. The elastically distorted section 11 of a section contacting the iron core section 8b of the yoke 1 is formed thinner than any other section, and is formed in contact with the top surface of the iron core section 8b, as a whole, and is recessed to the internal section of the yoke 1. When a stator 8 is fitted in the yoke 1, then the elastic section 11 is easily deformed, and the yoke 1 is fixed without applying pressure strongly to the stator, and with keeping a distance between the magnetic pole section 8a of the stator 8 and the magnetic poles of the rotor 2, uniformly.

Further, the paper feed pitch is set to the multiple of the number of printing elements arranged in the pitch between the adjoining lines. Thereby, a plurality of lines can be simultaneously printed through unilateral printing operation and in the case where bilateral printing is performed, each line is never superimposed on each printing element and printing can be performed so that the printing direction is reversed line by line. Then, printing speed can be increased and printing can be effectively performed.

Title: Control circuit of inverter device
Inventor: TADA HIDEAKI
IPC: H02M7/48
Filed: 1984-09-20
Abstract: PURPOSE:To shorten an arrival time to the desired frequency by controlling the variation in a command output to an inverter device when a load current is the prescribed level or higher, thereby preventing a control from stalling. CONSTITUTION:An inverter device 3 is controlled by a command output signal I0, and this output is driven by a motor 4. This control circuit has the first comparator 1, a voltage divider PD, an integrator 2, the second comparator 5, and a switch 6 of a field effect transistor. Thus, the comparator 1 compares a command input signal Ic with a command output signal I0, inputs its output through the divider PD to the integrator 2 to obtain the signal I0. In this case, the comparator 5 compares the current level IL of the motor 4 with a reference level signal Ir, and closes the switch 6 by the output signal 5a when the signal IL corresponding to the frequency of the inverter 3 exceeds the signal Ir. Thus, the input voltage of the integrator 2 drops, suppresses the output signal I0 to prevent the motor 4 from stalling.

At the decoder, after the random number ri is generated in advance, this is converted to the Ri, the Ri is substrated from the received cryptogram Ci and it generates the Mi. Further, the Mi is converted to the division message mi by an original body correspondence part 9, this message mi is connected to i=1 to l and an original message m is restored.
