Title: Stepping motor drive circuit
Inventor: KITAMURA SHINGO
IPC: H02P8/14
Filed: 1998-12-07
Abstract: PROBLEM TO BE SOLVED: To improve symmetry of current waveform when a current is fed to motor winding and when a current is drained therefrom by applying a constant current signal to both the P-ch side and N-ch side of a power switching control means performing bipolar drive. SOLUTION: In a five-phase stepping motor drive circuit, a PWM signal 501 is applied to both P-ch and N-ch FET drive sections 306, 307 in order to equalize the switching characteristics of P-ch and N-ch FET arrays. When the switching characteristics of P-ch and N-ch FET arrays are equalized, the current flowing through phase B has a substantially ideal waveform and rotational fluctuation occurring at a quarter of period of the rotational frequency of the stepping motor can be suppressed. Since the waveform is improved, rotational fluctuation occurring at other period of the stepping motor can also be suppressed.

Title: Angular velocity sensor
Inventor: MIZUNO TAKUYA
IPC: G01C19/5712
Filed: 1999-12-22
Abstract: PROBLEM TO BE SOLVED: To improve detection accuracy by preventing inclination of a vibrator in an angular velocity sensor supported inside. SOLUTION: A support part 51 consists of a circular central support part 51a and an extended support part 51b and so the contact area between the support part 51 and a glass plate 10 is large and the contact force is improved. The stability of the support part becomes very good and the inclination of the vibrator 50 is surely prevented. As the contact area between the support part 51 and the glass plate 10 is increased and the contact force is improved, the inclination of the vibrator 50 due to gearing of the circular part 11 and conductor wire 14 does not generate. As the results, detection accuracy improves. As the inclination of the support part 51 is prevented, the yield of production also increases.
