A hearing aid programming system with a host computer for providing at least one hearing aid program and having at least one personal computer memory card international association (PCMCIA) defined port in combination with a PCMCIA card inserted in the port and arranged for interacting with the host computer for controlling programming of a hearing aid. The host computer provides power and ground to the PCMCIA card and provides for downloading the hearing aid programming software to the PCMCIA card upon initialization. A microprocessor on the PCMCIA card executes the programming software. A portable programming arrangement utilizes a portable multiprogram unit to store one or more hearing aid programs which may be downloaded from the host computer. The portable multiprogram unit includes a wireless interconnection for transmitting selected ones of the programs to hearing aids to be programmed.

Method and apparatus for applying unique composite indicia or markings to a succession of articles, in which each unique composite indicium comprises two or more indicia. At least part of each of the indicia may be co-located at a predetermined location on the article with such co-location being unique or distinct for each composite indicium for each article. The indicium may be overprinted with one or more images, logos or color-schemes. A code (e.g. an alphanumeric string) that is stored in a database may be derived from the composite indicium from one or more mathematical properties. The code may be later accessed for identifying or verifying the article with the indicium.

A speaker box that is furnished inside a main body thereof with a curved sound channel, and used in a back-load horn, adopts a structure comprising two lateral plates and a plurality of intermediate plates interposed between the lateral plates, which plates are joined in a laminated form and secured with bolts. The intermediate plates individually have curved walls that jointly define a sound channel inside the main body of the speaker box.

On object of the invention is to provide a non-volatile memory device, in which data can be added to the memory device after a manufacturing process and forgery and the like by rewriting can be prevented, and a semiconductor device including the memory device. Another object of the invention is to provide a highly-reliable, inexpensive, and nonvolatile memory device and a semiconductor device including the memory device.

For the purpose of providing a method of safely and inexpensively producing a fermented plant extract containing an immunopotentiator at a high concentration, the method for fermentation and culture of the present invention ferments a plant component such as wheat flour using Pantoea agglomerans which is a gram negative bacterium which lives in a symbiotic relationship with a plant such as wheat and apple. It becomes possible to remarkably augment an immunopotentiation action which the plant has. In addition, these are not contaminated with impurities derived from animal components, and thus these are highly safe.

A complex inductor according to the present invention changes its magnetic coupling polarity according to currents flowing its two inductors. The complex inductor includes a first magnetic member, around which first and third windings are formed, and a second magnetic member, around which second and fourth windings are formed. A first inductor is formed by connecting the first winding to the second winding, and a second inductor is formed by connecting the third winding to the fourth winding. The two magnetic members are made of a magnetic material having a magnetic permeability that gradually decreases as its magnetic flux density is increased. When the two windings are interconnected in a direction in which induced voltages generated in these windings by the current flowing in the second inductor weaken each other, the magnetic coupling polarity between the first and second inductors changes according to the current flowing in the inductors. The two inductors are magnetically coupled so that, when one of the two inductors stores energy, the current flowing in the other inductor increases, and when one of the two inductors releases energy, the current flowing in the other inductor decreases.

When an electrode is formed over an organic layer, a temperature is limited because the organic layer can be influenced depending on a temperature in forming the electrode. Therefore, there are problems that an expected electrode cannot be formed, and miniaturization of an element is inhibited. The present invention provides a structure of an organic memory element in which two electrodes are provided in the same layer as two terminals of the memory element, and a layer containing an organic compound is provided between the electrodes. By narrowing a distance between the two electrodes, writing can be performed at low voltage. In addition, a structure of the memory element is simplified, and the area of the memory element can be reduced.
