Title: Switching regulator
Inventor: YASUI RYUICHI
IPC: H02M3/28
Filed: 1996-10-23
Abstract: PROBLEM TO BE SOLVED: To provide a switching regulator the conversion efficiency of which is not much deteriorated even when the load becomes lighter and which can operate stably. SOLUTION: The primary- and secondary-side windings of a switching regulator are formed by winding an electric wire 222 around a bobbin 221. A transformer 22 is formed by mounting E-cores 223A and 223B on the bobbin 221 wound with the electric wire 222. The gap between the C-cores 223A and 223B is eliminated or reduced by forming a projecting section 224 on the abutting surface of the central leg 223Ac of the E-core 223A, namely, the surface of the central leg 223Ac of the E-core 223A facing the central leg 223Bc of the core 223B. When the load is light, the current flowing to the transformer 22 becomes smaller and the inductance becomes larger.  Therefore, a switching regulator can operate stably even when the load becomes lighter, because the projecting section 224 eliminates the occurrence of an abnormally high oscillation frequency, intermittent oscillation, etc., which occur when the projecting section 224 does not exist. Since the increase of the current is relieved, the power loss of a switching transistor becomes smaller and the efficiency deterioration of the regulator is reduced even when the load is light.

Title: Optical information recording medium
Inventor: IIDA TAMOTSU
IPC: G11B7/24085
Filed: 1988-11-09
Abstract: PURPOSE:To obtain the medium having high reliability and large recording capacity by forming guide grooves of recording tracks running a swelling deformation region in such a manner that the gain of the tracking error signal obtd. from the swelling deformation region is smaller than the gain obtd. from the other parts of the same recording tracks. CONSTITUTION:The guide grooves of the recording tracks passing the hygroscopic swelling deformation region 13 in a prepit forming part are formed to the width W1 smaller than the width W2 of the other parts on the same recording tracks. As a result, the tracking signal level read out of the guide grooves 9 in the region 13 (the intensity level of the reflected and diffracted light or the intensity level of the transmitted and diffracted light from the grooves 9) decreases and even if the intensity of the light from the grooves 9 is unbalanced by the influence of the swelling, the track offset quantity is decreased and tracking noises are decreased. The stable tracking servo is thus assured. The swelling deformation generally appears more strongly in the recording near the prepits 8. The adjustment can be made by forming the grooves 9 in the swelling deformation region 13 to the width smaller the nearer the prepits 8 or wider the further therefrom in this case.
