Abstract: The invention relates to oil composition comprising 0.1 to 59.8% by weight of a triglyceride, 40 to 99.7% by weight of a diglyceride, 0.1 to 10% by weight of a monoglyceride and at most 5% by weight of a free fatty acid, wherein contents of &ohgr;3 type unsaturated acyl groups having at least 20 carbon atoms and monoenoic acyl groups in acyl groups constituting the diglyceride are 15 to 89.5% by weight and 10 to 84.5% by weight, respectively; and oral medicinal compositions and foods comprising such an oil composition.

Abstract: Disclosed herein is an oil composition containing a diglyceride, in which at least 55% by weight of the constitutive acyl groups are unsaturated acyl groups, and 15 to 100% by weight thereof are &ohgr;3 type unsaturated acyl groups having at least 20 carbon atoms, in an amount of not less than 10% by weight, but less than 40% by weight, and a triglyceride, in which at least 70% by weight of the constitutive acyl groups are unsaturated acyl groups, and 5 to 80% by weight thereof are a linoleyl group, in an amount of 40.1 to 89.8% by weight. The composition effectively develops the physiological functions derived from &ohgr;3 type unsaturated fatty acids, such as antiarteriosclerotic effect, and is excellent in oxidation stability, flavor and the like. Foods and medicines containing such an oil composition are provided.

Abstract: A communicating pipe for introducing atmospheric pressure to an air vent circuit changeover valve has an intermediate portion provided in a fuel tank and slanted portions extending obliquely upward. The intermediate portion has a drain pipe wherein a drain hole is provided. Liquefied fuel in the communicating pipe is gathered to the intermediate portion through the slanted portions and drained from the drain pipe into the fuel tank. Thus constituted communicating pipe prevents a clogging of liquefied fuel in the communicating pipe.

Abstract: The process for increasing the bulk of a food having a decreased bulk in the present invention comprises applying a means of internal vibration heating such as a microwave oven to a food having a decreased bulk, which has been prepared by subjecting a porous food comprising a cereal flour and water, such as breads, to a treatment such as compression, and has maintained the thus decreased bulk. The food of which the bulk has been increased by such a way has a bulk comparable to the one immediately after baking and exhibits excellent taste and feelings during eating.

Abstract: A diglycerol saturated fatty acid ester mixture containing a diglycerol saturated fatty acid diester(s) having two monohydroxymonoacyloxy(iso)propyl groups, wherein the acyl groups are derived from saturated fatty acids having 10 to 24 carbon atoms and two acyl groups are the same or different from each other, in an amount of 80% by weight or more based on the total weight of the diglycerol saturated fatty acid diesters contained in the mixture, and a diglycerol saturated fatty acid diester(s) in an amount of 45% by weight or more based on the entire weight of the mixture, is used as a modifier for protein-containing materials, in particular, for the control of the stickiness on the surface of the dough during the production thereof, for the improvements of the mechanical resistance and the handleability, and for the improvements of the feelings during eating, such as softness.

Abstract: A charge transfer device includes a source barrier electrode arranged on portion of an insulation film which lies between a source region and a signal input electrode over a semiconductor substrate and formed to isolate the source region from the signal input electrode, and a source storing electrode for storing substantial source charge. A pulse signal is supplied to the source barrier electrode and source storing electrode, and a D.C. source voltage is applied to the source region.

Abstract: This device comprises transfer electrodes and read electrodes. The read electrode operates in accordance with two modes. Where it operates based on the charge detection mode, a charge below the read electrode is read out in accordance with the floating gate system, so that a charge detection signal is produced. On the other hand, where it operates based on the charge transfer mode, the read electrode performs a function equivalent to the transfer electrode. This device further comprises selector means, thus permitting the read electrode to select either of two modes to operate in a selected mode.
