    Abstract: A coupling/uncoupling device includes a columnar member configured by a divided pair of semicircular members, and a pair of coupling members forming a circular holding section that holds the columnar member. The circular holding section includes a circular inner surface section with which an outer circumferential surface of the columnar member is in slide contact, the circular inner surface section being formed from inner circumferential surfaces of a semicircular section in one coupling member and a semicircular section in the other coupling member. The columnar member is configured to be rotatable in both clockwise and counterclockwise directions along the circular inner surface section about a reference position where a contact surface of the pair of coupling members and a dividing surface of the columnar member are flush with each other.

  • Patent number: 9516042
    Abstract: A main server and a mirror server hold the same content. A server switching apparatus sets only one of the web servers to be active. In the case where the mirror server has not been attacked in an immediately-previous operating period, the server switching apparatus switches from the main server to the mirror server. Upon receiving a request from a client computer, the server switching apparatus transfers the request to the active web server. The active web server then sends the requested content.

  • Patent number: 6667812
    Abstract: An information processing apparatus acquires identification information which specifies an interpreting program for interpreting a device control language, the specified interpreting program being operable in an external device connected to the information processing apparatus. It is discriminated whether a selected first control program corresponds to the device control language interpreted by the specified interpreting program. If it is discriminated that the selected first control program does not correspond to the device control language interpreted by the specified interpreting program, a second control program corresponding to the device control language interpreted by the specified interpreting program is selected from a plurality of control programs. Data is output to the external device using the first control program or, if it is discriminated that the first control program does not correspond to the device control language, the selected second control program.

  • Patent number: 6330989
    Abstract: A conduit guide is disclosed for attaching bicycle cables or conduits to the bicycle frame. Basically, the conduit guide includes a strap and a retainer. The strap and retainer are designed to secure a bicycle conduit to the bicycle frame without exerting any substantial radial compressive force on the conduits. The strap is preferably a plastic tie-type of band clamp. Of course, other types of band clamps can be utilized. The retainer includes a U-shaped conduit retaining portion and a foot portion. The foot portion includes a first foot section and a second foot section integrally formed at the ends of the leg sections of the conduits retaining portion. A strap receiving recess is formed between the foot portion and the conduit retaining portion to secure the retainer to the bicycle frame without exerting a compressive force on the conduit. In alternate embodiments, a bridge is formed between leg sections for added stability.

  • Patent number: 6304335
    Abstract: A printing system includes a host computer and a printer. The host computer includes a memory which store process steps that are executable by a processor, and a processor. The processor executes the process steps stored in the memory (1) to divide encoded image data in a page of encoded image data into blocks, each block having a size which is less than a storage capacity of a buffer on a printer, and (2) to transmit the blocks of encoded image data to the printer. The printer includes a memory which stores process steps that are executable by a processor, and a processor. The processor executes the process steps stored in the memory (1) to store a predetermined amount of encoded image data in a buffer, (2) to control a printer engine to print images based on the encoded image data stored in the buffer, and (3) to store additional encoded image data, including blocks of the encoded image data, in the buffer in place of the encoded image data for which images have been printed.

  • Patent number: 6265288
    Abstract: A method of fabricating a silicon-based thin-film photoelectric conversion device, where a plasma CVD process is used to deposit a polycrystalline photoelectric conversion layer. During the deposition of the photoelectric conversion layer, the temperature of the underlying layer is less than 550° C., the pressure in the plasma chamber is more than 5 Torr, and the ratio of the flow rates of a hydrogen gas and a silane-type gas is more than 50. In addition, one of the following operations is carried out during the deposition to change the relevant parameters between the start and end of the deposition. First, the distance between the plasma discharge electrodes is increased gradually or in steps. Second, the pressure of the reaction chamber is increased gradually or in steps. Third, the flow rate of the silane-type gas is increased gradually. Fourth, the plasma discharge power density is reduced gradually or in steps.
