Inventor: NAGAYASU TOMOYOSHI
IPC: G02B6/02
Filed: 2009-03-11
Abstract: <P>PROBLEM TO BE SOLVED: To solve a problem wherein, since a conventional double clad fiber has an identical cross-sectional shape with respect to a fiber length direction, when skew light without contributing to laser light generation is generated, the skew light is not reduced.  <P>SOLUTION: This double clad fiber including a core 11 including a laser medium for generating and transmitting laser light, an inner clad 12 for transmitting excitation light and an outer clad 13 for trapping the excitation light therein is structured such that the cross-sectional shape of the inner clad 12 consists of an excitation region having a generally-circular cross-sectional shape for introducing the excitation light therein, and a generally-circular oscillation region for transmitting the laser light; at least either the excitation region or the oscillation region has a flat part forming a part of a circumference of the cross-sectional shape with a straight line; and the length of the flat part changes along the length direction of the double clad fiber.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Title: Insulated dc-dc converter
Inventor: FUJITA SATORU
IPC: H02M3/28
Filed: 2009-03-12
Abstract: <P>PROBLEM TO BE SOLVED: To provide an insulated DC-DC converter for improved control precision of an output voltage.  <P>SOLUTION: When a switching element 4 is turned off, a main winding 11a of a choke coil 11 is applied with a voltage Vout of a load 6, or both-end voltage of a capacitor 13, since a diode 7 is turned off and a diode 8 is turned on. Here, a voltage which is proportional to a turn ratio occurs at an auxiliary winding 11b of the choke coil, and a hold circuit 31 sample-holds at the timing of gate-off of the switching element 4 through an amplifier 30. Just after gate-off of the switching element 4, sample-holding is performed at the timing which is delayed by a delay circuit 32 because both end voltage of the choke coil 11 transitionally fluctuates from negative voltage to positive voltage. The pulse width of the switching element is controlled based on the voltage that has been sample-held.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To provide a low-floor ignition coil by optimizing layout in a housing.  <P>SOLUTION: In relation to a central core 13 and a peripheral core 18 housed in the housing 10, a center line L1 longitudinally penetrating the central core 13 is positioned on the lower side with respect to a center line L2 penetrating a middle point of a first side part in the height direction when it is assumed that a direction in parallel to the center line L1 and orthogonal to the longitudinal direction of the central core is the height direction. That is to say, the peripheral core 18 is arranged by being offset on the lower side relative to the central core 13. Thereby, since a terminal processing part 30 located above the first side part 18a is offset on the lower side relative to a housing 510 where a center line L3 of a central core and a center line L4 of a peripheral core are conventionally set nearly identical, the height H of the housing 10 is reduced, and thereby this ignition coil 100 is downsized.  <P>COPYRIGHT: (C)2010,JPO&INPIT
