摘要:
A microwave plasma CVD apparatus for forming a functional deposited film comprises a film-forming chamber having a discharge space, a substrate holder, and apparatus for introducing a film-forming raw material gas into the film-forming chamber, for transmitting microwaves into the film-forming chamber to apply microwave energy to the raw material gas so that the raw material gas is converted into plasma, and for simultaneously applying a bias voltage to the plasma generated in the discharge space from an external system to control the plasma potential. A mechanism is provided for temporarily suspending the application of the bias voltage in the case when abnormal discharge occurs, while monitoring the fluctuation of the bias voltage to be applied to the plasma, to thereby inhibit the occurrence of abnormal discharge.

摘要:
Disclosed is a collagen powder and/or a collagen derivative powder, which are obtained by dispersing in a hydrophilic organic solvent a crude collagen precipitate which comprises 12 to 50% by mass of a collagen precipitate and/or a collagen derivative precipitate having an average particle size of 1 to 1,000 μm, recovering solids and then drying the solids. By dispersing the crude collagen precipitate in the hydrophilic organic solvent, the resulting precipitates can be dehydrated, so that drying of the thus obtained solids can be done by air-drying. In addition, the resulting collagen powder and/or collagen derivative powder exhibit excellent solubility due to an increased specific surface area and also have excellent ease of handling with the average particle size being 8 to 1,000 μm.

An object in a virtual reality space is made perform complicated movements. A user (or a keeper) who controls an object (or a pet) in a virtual reality space enters a command at the client terminal of the user by means of chat operation. The entered command is sent to a server. The server has a table listing the relationship between commands and movements to be performed by the object in the virtual reality space. For example, the relation is between command “Jump” and movement of jumping. The server interprets the received command by referencing this table. The interpretation result is sent to the client terminal. On the client terminal, the object (the pet) in the virtual reality space performs complicated movements such as dancing according to the received interpretation result.
