A light-emitting device according to the present invention includes: first insulators (4) arranged so as to face each other; an emitter (2) arranged between the first insulators; a second insulator (5) functioning as a base for the first insulators and the emitter; an electrode (6) arranged to face, or contact with, the first insulators partially; another electrode (10) contacting with the second insulator and interposing the second insulator between the electrode and itself; and a light-transmitting substrate (8) that faces the second insulator with the first insulators interposed somewhere and with the emitter interposed elsewhere. If the first insulators are extended to reach the light-transmitting substrate on a cross section including the first and second insulators, the emitter and the light-transmitting substrate, the ratio of the cross-sectional area of the emitter to the combined cross-sectional area of the first and second insulators and the light-transmitting substrate is defined so as to fall within a predetermined range.

A non-volatile storage device comprises a non-volatile memory into which data is written per unit area, and a memory controller for controlling writing of data into the non-volatile memory. The memory controller comprises a first storage section for holding data input from the outside of the device, a first control section for writing data which is held by the first storage section and whose amount corresponds to the unit area, into the non-volatile memory in a unit area-by-unit area basis, and writing data which is held by the first storage section and whose amount is less than the unit area, into a second storage section, and a second control section for writing data held by the second storage section into the non-volatile memory.

The present invention relates to a method for analyzing residual agricultural chemicals which comprises the steps of acting a reduced glutathione as a reactive substrate and a glutathione transferase serving as a catalyst for the reaction on a carbofuran derivative or a methomyl derivative as a carbamate type agricultural chemical of a new series to thus derivatize the agricultural chemical into a substance having a high choline esterase-inhibitory activity; reacting the substances formed through the derivatization reaction with a choline esterase; and then detecting the presence of the agricultural chemical as the new series of carbamate type one included in a sample to be examined on the basis of the changes in the choline esterase activity thus detected. The method of the present invention may serve as a powerful tool for the detection of the residual agricultural chemicals in grains such as rice and the detection of the content of agricultural chemicals remaining in agricultural products such as vegetables and fruits.

Hardening is accomplished by heating a longitudinal section of a workpiece such as an odd-shaped bar, and by quenching while constraining the workpiece section in dies. The quenching is executed while the workpiece is pressed in a direction perpendicular to its longitudinal direction by a pressing device which is installed adjacent to the workpiece section constrained in the dies. Warping by quenching can thus be minimized in odd-shaped workpieces, such as an automobile steering rack bar.

The present invention provides a multilayer ceramic capacitor in which electrode metal layers and dielectric ceramic layers are laminated alternately and its dielectric constant peak is present at a temperature below −50° C. The multilayer ceramic capacitor is at least one selected from a multilayer ceramic capacitor to be incorporated into an electric circuit in which an electric field of at least 200 V/mm is applied to dielectric layers as a DC bias electric field and an alternating current at a frequency of at least 20 kHz is superimposed and a multilayer ceramic capacitor to be incorporated into an electric circuit in which an electric field of at least 200 V/mm is applied to dielectric layers as an AC electric field. As the dielectric ceramic, a ceramic containing lead atoms whose amount is indicated by being measured in the form of PbO, which is at least 30 mol %, particularly a compound with a perovskite structure represented by ABO3 is used. Thus, an inexpensive large-capacity multilayer capacitor that has thermal resistance and is stable for a high DC bias voltage and a high frequency voltage, and a low loss switching power supply using this capacitor can be provided.
