Filed: 1986-10-21
Abstract: PURPOSE:To measure optical characteristics of an optical disk in an actual use state by irradiating the optical disk with converged laser irradiation light and performing tracking control, etc., over the irradiation light according to the reflected light. CONSTITUTION:Linearly polarized laser light from a laser 1 is made into parallel light 2, which passes through a lambda/4 plate 3 to become circular polarized light Pa. Then, the angles of rotation of a polarizer 4 and a lambda/4 plate 5 which have specific angles of rotation to a certain reference surface are selected to irradiate an optical element 6 to be measured with passing circular polarized light Pa as desired polarized irradiation light Pb. Then, projection light Pc which is transmitted or reflected by the element 6 is passed through the lambda/4 plate 7 and an analyzer 8 which have angles of rotation to the reference surface and then its quantity of light Pd incident on a photodetector 9 is detected. The Stokes' parameter of the projection light Pc from the element is found by setting the angles of rotation of the lambda/4 plate 7 and analyzer 8 to four conditions and measuring the quantity of the incident light Pd under the set conditions.

Title: Manufacture of laminated-chip inductor
Inventor: NAKAZAWA CHIKASHI
IPC: H01F41/04
Filed: 1990-09-20
Abstract: PURPOSE:To prevent the L value from fluctuating under the influence of a magnetic field by placing the burning elimination substance between a magnetic substance sheet and electric conductor patterns. CONSTITUTION:Burning elimination paste-made burning elimination patterns 18a are printed on an unburned magnetic substance sheet 12, with one pattern at a time. On the patterns 18a, electric conductor patterns 14 are printed one by one. Then, burning elimination patterns 18a are printed on the patterns 14, with one pattern at a time. After the patterns 18a, 18b and 14 are dried, the pattern-printed sheets 12 are so laminated that the patterns 14 may be successively connected to each other at the end. After that, the laminated sheets 12 are heated and stuck to each other to form a joined body. The joined body is cut at the specified positions to make laminated chips. By this method, a space is made on the boundary between the magnetic substance and the electric conductor. When the magnetic substance and the electric conductor expand or shrink independently of each other under the influence of a magnetic field, no internal distortion occurs due to a difference in an expansion coefficient between the magnetic substance and the electric conductor and thus the L value hardly fluctuates owing to a magnetic field.

IPC: H03K3/55
Filed: 1993-10-08
Abstract: PURPOSE:To obtain a small sized pulse power supply circuit without loss. of a high voltage characteristic with a low loss and a high efficiency and an excellent high frequency characteristic by using a saturable transformer for pulse voltage boosting and pulse compression. CONSTITUTION:A charging power supply 1 and a load 9 are coupled via a saturation transformer 10. When the power supply 1 charges a charging capacitor 2, a thyratron 3 is conductive to supply an exciting current to a primary winding of the saturation transformer 10, a boosted voltage is produced at a secondary winding to charge a charging capacitor 11. As soon as the charging is finished, the saturable transformer 10 is saturated to supply a current to a peaking capacitor 8. In this case, the pulse width of the pulse at the primary and secondary windings depends on the product of constants of the respective circuit components, the product at the secondary winding is set smaller than the product of the primary winding to compress the pulse width and then the pulse with a fast leading is fed to the load 9. Thus, it is not required to provide a pulse compression element and the size of a saturable reactor for the transformer is reduced to attain miniaturization of the circuit and high efficiency of the circuit.
