A light emitting element includes an LED element that emits an excitation light having a single peak wavelength within a range of greater than or equal to 380 nm and less than or equal to 500 nm; a fluorescent body to which at least a portion of the excitation light enters to emit fluorescence; and a light extraction surface that emits an output light formed by superimposing the excitation light and the fluorescence. The output light exhibits light emission over a range of at least greater than or equal to the peak wavelength of the excitation light and less than or equal to 1050 nm, and all of the output light have a light emission intensity of greater than or equal to a light emission intensity at 1050 nm within a range of at least the peak wavelength of the excitation light to 1050 nm.

A foil seal lamp in which even when a high temperature of the seal area is reached oxidation of the molybdenum metal foils and the molybdenum outer leads which have been placed in the seal area can be reliably prevented, and in which a long service life can be obtained. is achieved by providing the surfaces of the metal foil and the outer lead which are placed in the seal areas with protective coatings of crystalline molybdate. An increase in the amount of protective coating that can be carried is produced by surface roughening the outer leads.

A plurality of orderers with their own code systems procures materials from companies (supply companies) with which the orderers have business relations. In this material procurement system, a name register master is provided for making correspondence between goods name codes provided by each of the supply companies and material codes of the orderers. When necessary materials are procured from the supply company, the orderer goods name codes are used for specifying the materials. Further, an order processor is provided. The order processor refers to the name register master, and combines orders of the materials with a same orderer goods name, if the same goods name of the supply company is in the name register master. The order processor also divides the orders and orders to another company by referring to the name register master, if the materials in a quantity beyond a predetermined number must be ordered.

A current clamp circuit which can easily restrict an output current externally in an output current amplifier circuit using a current buffer IC, is provided. The current clamp circuit restricts the output current in the output current amplifier circuit for amplifying the output current by using the operational amplifier and the current buffer IC wherein the resistor is connected to the output terminal of the current buffer IC, and the output current restriction unit for restricting the output current is connected to the current buffer IC and the resistor in parallel.
