A process for preserving process cheese which comprises admixing with natural cheese during the steps of preparing process cheese from natural cheese sorbic acid-containing powder or granules having particle diameter of 300 microns or more comprising 5-90% by weight of finely divided sorbic acid and 10-95% by weight of an easily water-soluble substance which is a solid at normal temperature.
摘要:
A food additive composition admixed with fish mince consisting of a hydrophilic powdery colloidal solid having a particle size smaller than 20 mesh and comprising 60 to 99% of a sugar alcohol or a sugar, 30 to 0.5% of a food-grade surface-active agent and 30 to 0% of an edible oil or fat. The food additive can be prepared by adding a food-grade surface-active agent and an oil or fat to a melt or aqueous solution of a sugar alcohol or a sugar to dissolve them or disperse them in a fine particlar form, optionally adding a sugar alcohol or a sugar as a seed crystal, solidifying the solution or dispersion to form a colloidal solid, stabilizing the colloidal solid by crystallization, optionally drying the stablized solid, and pulverizing it to a particle size smaller than 20 mesh.
摘要:
A semiconductor blue-light-laser apparatus for emitting laser beams with high positional accuracy, which is achieved by mounting a semiconductor laser element on a semiconductor substrate with high accuracy and reliability, and a production method of the apparatus. A recess in a surface of the substrate has a p-type layer 100, which is coated with the SiN layer 105, Ti layers 110a and 110b, Au layers 111a and 111b, heat sink layer 113, and solder layer 114. Semiconductor laser element 10 is placed and fixed on Au layer 111b. Heat sink layer 113 is inserted between Au layer 111a and Ti layer 110b and is approximately 20 μm thick. Reflection unit 50 for reflecting laser beams LB includes at the surface thereof Al layer 116 and dielectric layer 117 as a reflection layer that provides a high refractive index for blue light laser beams.
摘要:
A battery charger is disclosed comprising a pair of charging terminals to which a secondary battery may be connected, a power source for supplying the charging terminals with a charging voltage, a recharging detector for detecting the degree of recharging on the secondary battery on the strength of the voltage between the charging terminals, and a timer operative to measure a predetermined time beginning when the recharging detector detects that the degree of recharging on the second battery has reached a predetermined degree set within a range from seventy percent to ninety percent of full recharging. The invention further includes a first recharging indicator, for example an LED, which indicates that the secondary battery is being charged up until the timing operation commences. Once the timing operation begins, a second recharging indicator, for example a differently colored LED, indicates that the secondary battery has been charged to the predetermined degree and is receiving a final charge during the timing operation.
