Title: Pulse motor drive circuit
Inventor: MINAMINO KAZUYA
IPC: H02P8/12
Filed: 1994-12-09
Abstract: PURPOSE: To provide a pulse motor drive circuit which has a simple constitution and can drive a pulse motor by sufficiently reducing the fluctuation of the torque of the motor by using a one- or two-phase excitation drive system. CONSTITUTION: A reference voltage generated from reference voltage generating circuits 3 and 4 becomes a first level during the non-exciting period of each phase, second level which is higher than the first level during a two-phase exciting period, or third level higher than the second level during a one-phase exciting period. When capacitors are connected in parallel with the resistors of the circuits 3 and 4, the variation of the reference voltage between each level becomes smoother. A constant-current drive circuit 9 supplies exciting currents to the coil of each phase of a pulse motor 20 based on the level of the reference voltage.  In case the falling timing of the pulse signal given to the circuit 9 is delayed by means of fall delaying circuits 5, 6, 7, and 8, an exciting current does not become '0' momentarily, but after the current drops to a one-stage lower level, when the exciting period is shifted from the two- phase exciting period to the non-exciting period.

Title: Recording information carrier and molding method therefor
Inventor: YOSHII MASAKI
IPC: G11B7/24047
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To prevent warp deformation without generating sinks and to prevent tracking errors by providing a void part or a foamed part on a thick part at the center part of a thin substrate turned to a high density such as a DVD. SOLUTION: A gaseous body can be injected from a substrate upper surface other than the same gate to which fused resin is injected and filled or a part near it. In this case, in order to prevent the local projection part of the substrate by gas injection port installation, it is preferable to provide a recessed part on a gas injection port part. Since the pressure difference of the inner peripheral part and outer peripheral part of the substrate is suppressed to be extremely small, the warp deformation of the substrate by the nonuniformity of resin filling is made less than the half of a conventional technique. Also, as the result of such low pressure molding, the double refractivity of the substrate is suppressed to be small as well. Further, on the substrate provided with the thick part 10 on the substrate center part, the effect of preventing the sinks of the thick part is provided.
