摘要:
A p type group III nitride semiconductor layer can be manufactured without causing its crystal deterioration, and without requiring any complicated post-treatment, by repeating a plurality of times the following steps: the step A of growing a group III nitride semiconductor layer containing p type impurities; the step B of discontinuing the growth of the group III nitride semiconductor layer by stopping supplies of the respective material gases and the carrier gas, and replacing an atmospheric gas within a film forming apparatus with an inert gas, and reducing a temperature of the substrate from a growth temperature; and the step C of resuming the growth of the group III nitride semiconductor layer by again raising the temperature of the substrate and supplying the material gases and the carrier gas into the film forming apparatus. Thereby, the activation of the semiconductor layer is attainable by releasing hydrogen incorporated into the semiconductor layer, and reducing thermal damage, resulting in suppressing the crystal deterioration.

Provided is a light emitting element capable of improving light extraction efficiency and suppressing the nonuniformity of emission intensity distribution over the entire surface of a light extraction surface. The light emitting element is provided with a semiconductor multilayer body having an n-type semiconductor layer and an emission layer and a p-type semiconductor layer, and an electrode pad connected to the p-type semiconductor layer. The semiconductor multilayer body has a large number of projections on one main surface thereof through which the light from the emission layer is emitted. The main surface of the semiconductor multilayer body has a first region located in the vicinity of the electrode pad, and a second region being further separated from the electrode pad than the first region. The interval between the projections in the second region is smaller than that in the first region.

The present invention provides the simple operation for displaying the information that is expected to be necessary for the user and the simplified procedure of the hands-free operation when displaying the map information on the screen. The display device 20 in which an arrangement state of the screen can be selected between a first state and a second state displays on the screen the detailed information of a destination or its surrounding area such as parking lot information, an access route guide to the transportation facilities, and information of the facility of the destination is displayed on the screen if a change of the arrangement of the screen is detected, if the destination has been set in advance, and if a distance between a current position and the destination is within a predetermined distance. Further, it comprises a display control means 27 for displaying at least a portion of the information acquired by the information acquisition means 23 if the change in the arrangement state of the screen is detected after the external equipment detection means 25 detected the connection of the external equipment 4.
摘要:
Expression plasmids containing the full cDNA sequence of calf prochymosin and capable of expressing prochymosin gene in E. coli host cells are disclosed. A method is described for the preparation of said plasmids which comprises altering the spacing between the SD and ATG sequences within the E. coli trp promoter-operator region of the parent expression plasmid, pCR 701, which is known to express prochymosin gene in the E. coli host cells. These modified expression plasmids are designed to provide high expression levels of prochymosin.

A fuel injection type two-cycle engine for motorcycles. A fuel injection valve for injecting fuel into an air intake passageway at a predetermined timing is disposed on the upstream side of a reed valve in the air intake passageway communicating with an interior of the engine via the reed valve, with the injection port thereof directed towards the reed valve. An air intake pipe forming the air intake passageway extends nearly in the vertical direction from the upper surface of a crank case at an middle position between a crank shaft extending in the widthwise direction of the vehicle body and a transmission shaft separated from the crank shaft in the back and forth direction and extending in the widthwise direction of the vehicle body, and a fuel injection valve protrudes from this air intake pipe in the back and forth direction. The air intake pipe and the fuel injection valve are positioned between left and right vehicle body frame members above the engine, and a partition plate is provided between the vehicle body frame members and the engine main body.
摘要:
An electrolytic cell for producing a brine containing hydrogen peroxide is disclosed. Units for hydrogen peroxide production 3 and units for water electrolysis 2 are alternately arranged in the same electrolytic cell 1. Electrolysis is conducted while supplying hydrogen gas and oxygen gas generating in the respective water electrolysis units to a gas diffusion anode 11 and a gas diffusion cathode 13 of each unit for hydrogen peroxide production, to thereby obtain a brine containing hydrogen peroxide in a high concentration. Furthermore, because the anode of the hydrogen peroxide production units is a hydrogen gas diffusion anode having a reduced oxidizing ability, halogen ions contained in the seawater do not yield harmful halogenated organic substances.
