摘要:
Besides fixed display element information for merely displaying a fixed screen, variable display element information for variably displaying a variable display element whose display content changes, input element information representing the relationship of correspondence between the input means and an operation switch contained in a relevant component, and the operation program information for operating the relevant component as required, which are necessary for the relevant component to completely function as a component, are capable of being set and registered with respect to component data. In addition, the set and registered component is allowed to be handled in a component data unit when user screen data is generated. Accordingly, if the components are registered in a library, the possibility of use by a third party can be drastically increased, and the number of work steps during the screen generation by the user can be drastically decreased.

The present invention provides an easy and efficient method of introducing a foreign DNA into certain cells which have been considered difficult to be transformed by conventional methods.The present inventors have found that bis-benzimdazolyl compounds which specifically bind to DNA were useful as a carrier to introduce the DNA into a target cell. Foreign DNA was introduced into a host cell by exposing said cell to a suspension or a solution containing the foreign DNA-compound complex.

A schottky diode is disclosed which has a barrier electrode formed on a semiconductor substrate for creating a schottky barrier therebetween. Also formed on the substrate is a first resistive region which surrounds the barrier electrode. The first resistive region is higher in sheet resistance than the barrier electrode and also capable of creating a schottky barrier at its interface with the semiconductor substrate. A second resistive region is formed on the first resistive region via an insulating layer and electrically connected to the barrier electrode. The sheet resistance of the second resistive region is less than that of the first resistive region. The first and second resistive regions function to improve the voltage blocking capability of the diode, particularly at the time of instantaneous transition from forward to reverse bias. There is also disclosed herein a method of most efficiently fabricating schottky semiconductor devices of the foregoing general construction.

摘要:
In order to provide an ultrasonic probe capable of suppressing the influence of multiple reflections occurring on the interface of a transducer with a CMUT chip and a backing layer, an ultrasonic probe of the present invention has a structure where an acoustic lens 14, transducers 11-1 to 11-m, and a backing layer 12 are laminated. Each of the transducers 11-1 to 11-m has a CMUT chip, and the backing layer 12 is formed of a material with a value of substantially the same acoustic impedance as the acoustic lens 14.
