Title: Method and circuit for detecting out-of-step of stepping motor
Inventor: KONDO HIDEYUKI
IPC: H02P8/38
Filed: 1998-07-16
Abstract: PROBLEM TO BE SOLVED: To conduct out-of-step detection of a stepping motor with high precision using a simple structure. SOLUTION: This out-of-step detecting circuit 20 of a stepping motor 1 enhances resolution of a rotary encoder 3 so as to obtain pulse outputs out of 8 pieces of encoders during one step driving of the stepping motor 1, in place of discriminating out-of-step based on the absolute position of the stepping motor 1. If the number of pulses detected actually is 6 or more, it is discriminated that there is not generated out-of-step. This-out-of-step detecting circuit 20 ensures proper out-of-step detection even if a prescribed number of encoder pulses is not outputted because of mixing noise in the output of an MR element due to a change in magnetic field generated by driving the stepping motor.

Title: Information providing service system
Inventor: MORI TAKAHIRO
IPC: H04W76/02
Filed: 1998-07-16
Abstract: PROBLEM TO BE SOLVED: To freely and easily perform various setting by allowing a communication terminal device to set data based on various setting information transmitted from an information providing service center. SOLUTION: When a user selects an item which the user wants to set by using an input device 208, a communication terminal transmits the item selected by the user to a center through a PDC controlling part 203, a radio part 202 and an antenna 201. When a request comes from a terminal, the center inquires of a setting information database about setting information through an input- output interface by using an originating ID that is already stored. Inquired data is once stored in a setting information temporary storage buffer and when setting information corresponding to the originating ID exists, the setting information is transmitted to the terminal. The terminal side stores received setting information in a setting information receiving buffer 213, analyzes the setting information stored in the buffer 213 and extracts an item and setting content which should be set.
