Title: Switching power circuit
Inventor: YASUMURA MASAYUKI
IPC: H02M3/338
Filed: 1999-05-07
Abstract: PROBLEM TO BE SOLVED: To make it possible to reduce the cost and size of a switching power circuit by providing a soft start circuit and increasing switching frequency at start of switching operation. SOLUTION: When approx. 20 ms have passed after an AC switch SW is turned on, the switching frequency is started to be forcedly increased through operation of a soft start circuit 2, and thereafter, it is gradually reduced. As a result, operation is performed so that the time before secondary-side direct- current voltage raises to a steady-state level at start is lengthened. That is, whereas the steady-state level is conventionally reached in 20 ms or so after the AC switch SW is turned on, this circuit is controlled so that the steady-state level is reached in 100 ms or so after the AC switch SW is turned on. Thus, the cost and size of the circuit can be reduced. Also, power loss is eliminated, and the efficiency of power conversion is enhanced.

Title: Liquid crystal element
Inventor: OKADA SHINJIROU
IPC: G02F1/1339
Filed: 1984-06-22
Abstract: PURPOSE:To form uniformly and stably a spacing of as small as 1-2mum, between a pair of electrode substrates, by removing at least partly the adhesive agent coated part of the substrates to form recesses. CONSTITUTION:A pair of the transparent substrates 22a, 22b provided respectively with transparent electrodes 21, 21b are fixed by an adhesive agent and a liquid crystal is sealed therein. The adhesive agent coated part of the substrates 22a, 22b is at least partly removed, by which the recesses 220a, 220b are formed. The initial thickness of the adhesive agent can be taken large even if the inter- substrate spacing is made as slight as 1-2mum and therefore fine adjustment of the thickness under the pressure is smoothly executed. The uniform and smooth formation of the very small inter-substrate spacing is thus made possible without any defect at all in the adhered part.

Title: Waveguide device and dielectric characteristic measuring device
Inventor: TAKAHASHI TAKESHI
IPC: H01P7/06
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To easily and quickly measure dielectric characteristic by surrounding a waveguide space with a cylindrical metal inner wall and flat metal inner walls for blocking both its axial ends, and forming their crossing part into a recessed curved surface continued to both the inner walls over the whole circumference. SOLUTION: The crossing parts of a cylindrical metal inner wall surface 11 and flat metal inner wall, surfaces 12, 13 constituting a waveguide space 1 are made into metal recessed curved surfaces 14 continued to the cylindrical metal inner wall surface 11 and the flat metal inner wall surfaces 12, 13. In such a structure, since a harmonic current is smoothly carried along the curved surface 14 in the crossing part, and a harmonic electric field is not collected to a part of the metal, a high no-load Q value can be ensured. Therefore, the change of no-load Q value both in the insertion of a sample and in no insertion can be increased, and the dielectric characteristic of the sample can be measured with high precision.

Title: Injection timing control device of distribution type fuel injection pump
Inventor: IBUKI NORITAKA
IPC: F02D1/18
Filed: 1984-06-21
Abstract: PURPOSE:To prevent the generation of smoke and noise, by a method wherein, during low load operation at a highland, an injection timing is corrected to the advance angle side to prevent the occurrence of failure in ignition, and during high load operation, said correction is suspended. CONSTITUTION:During low load operation of an engine, a switching valve 60 is switched so as to interenergize ports 61 and 63 by means of a load sensor 65 and a driving circuit 66. In which case, when operative at a highland, with a bellows 46 of a flow rate control valve 43 expanded, a push rod 45 is moved upward, and thereby through-holes 50 and 51 are decreased in a communicating area, and a bypass flow rate, flowing from a high pressure chamber 35 of a timer cylinder 34 to a low pressure chamber 36, is reduced. Thus, a fuel pressure in the high pressure chamber 35 is relatively increased, a piston 33 is moved leftward, and an advance angle is effected on the injection timing of an injection pump. Meanwhile, during high load operating at a highland, the switching valve 60 interenergizes the ports 61 and 62, and this causes the bellows 46 to be contracted compared with that during low load operation, and causes suspension of correction of the injection timing to the advance angle side.
