Title: Switching power supply device
Inventor: KAGEYAMA AKIRA
IPC: H02M3/335
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To eliminate large ripples in an output voltage even under a light load. SOLUTION: If a load is reduced and a DC output voltage is elevated, a transistor Q1 is forcibly turned off by an on-period limiting circuit 22 and the on-period of a MOS-FET 1 is restricted. That is, the lighter the load, the shorter the on-period of the MOS-FET 1 and hence the smaller the energy supplied to the load. Therefore, the oscillation frequency of a nonstable multivibrator 3 is not significantly reduced under the light load and ripples in the output voltage can be significantly improved.

IPC: G21C3/34
Filed: 1987-04-06
Abstract: PURPOSE:To lower a pressure loss coefft. without deteriorating the strength of a spacer so that the driving power of a pump is reduced and flow stability is improved by forming annular elements to complete cylinders closed at the circumferential faces. CONSTITUTION:The spacer is formed by concentrically arranging the annular elements 1 and reinforcing the elements with an outer ring 2. The respective annular elements 1 are formed to the complete cylinders having no holes on the circumferential faces. The formation of the ends of the annular element 1 to an acute angled or streamlined shape is equally satisfactory. Notches and holes are not provided even in the case of providing projecting parts (dimples) to support fuel to the annular elements 1.

Title: Selective hydrogenation of unsaturated fatty acid derivatives
Inventor: YAN KUIPERU
IPC: B01J23/40
Filed: 1980-06-19
Abstract: Triglyceride oils, which contain besides fatty acids having two double bonds, fatty acids having more than two double bonds, are hydrogenated using palladium, platinum, rhodium and/or iridium as a catalyst, the catalyst being treated with dry ammonia. The hydrogenation is carried out at a temperature of at least 100 DEG  C. The hydrogenation progresses in a particularly selective manner. On using, for instance, soyabean oil, which contains about 55% of linoleic acid and 7% of linolenic acid, the amount of linolenic acid can be reduced to 2%, whereby more than 45% of linoleic acid is retained in the hydrogenated product. In case the catalyst is not treated, said amount is only about 35%.

CONSTITUTION:A low frequency component of an output signal of a photoelectric converting circuit 11 is eliminated by a low cut-off filter 13 and the signal becomes an AC signal from which a changed component only is extracted. Further, an output signal of the low pass filter is rectified by half-wave (or full wave) by a detecting and rectifying circuit 14 and becomes a value proportional to the change amount of an optical output signal 24. An optical output level at OFF is obtained by subtracting an output level of the rectifier circuit 12 and an output level of the detecting and rectifying circuit 14. The change amount of the optical output signal 24 is controlled to be constant by controlling the amplitude of a pulse current with the output level of the detecting rectifier circuit 14 proportional to the change amount of the optical output signal 24.
