摘要： PROBLEM TO BE SOLVED: To solve the problem that a user can not control a camera comfortably since a visual field intended by the user is different from the actual visual field of an image obtained after a delay time when a response delay of a camera image is large with respect to a camera control operation in a remote monitoring camera service.
SOLUTION: The camera controller predicts the visual field range of a camera image corresponding to the user's camera control operation, and then presents the predicted visual field range to the user.

摘要： PROBLEM TO BE SOLVED: To solve the problem in a forced chill circulation system refrigerator that an arrangement for distributing chill to the shelves at each stage of a refrigeration compartment has such a trend as power consumption of the refrigerator increases because the volume of chill flowing through the shelves or the door pockets is small and cooling performance of the refrigeration compartment is low. SOLUTION: The majority of chill 14 is delivered into the refrigeration compartment 1 from the back surface wall 2 and/or the upper surface wall 3 of the shelf 6 at the uppermost stage. At the second stage shelf 7 or even stage shelves from above, the gap between the forward end thereof and an opposite door pocket is narrowed whereas the gap between the back surface end thereof and the back surface wall is widened or a porous plate is employed partially in the vicinity of the back surface end of the shelf. At the uppermost stage shelf 6 or odd stage shelves, the gap between the forward end thereof and an opposite door pocket is widened or a porous plate is employed partially in the vicinity of the front end thereof or at the door pocket whereas the gap between the back surface end thereof and the back surface wall is narrowed so that the majority of chill 14 to the shelves and door pockets flows downward while snaking in the back and forth direction at the time of cooling operation of the refrigeration compartment.

摘要： PROBLEM TO BE SOLVED: To provide a refrigerator enabling reduction of power consumption consequent on defrosting, by improving the shape and disposition of a heater cover of a defrosting heater so that an evaporator can be defrosted efficiently in a short time. SOLUTION: The heater cover 13 of the defrosting heater 7 provided below the evaporator 6 inside a cooled air duct 5 is constituted so that an intake and a discharge opening are formed below and above a heater body 12 respectively, by a structure of substantially two members covering the front and rear sides of the heater body 12, respectively. At the discharge opening in such constitution, the upper end of the front-side member of the heater cover 13 is positioned above the upper end of the rear-side member and on the rear side thereof and also has eaves directed downward obliquely and, besides, the discharge opening is located at a position deviating rearward from the center of the cooled air duct 5.

摘要： PROBLEM TO BE SOLVED: To reduce power consumption by mounting a sensor for sensing the temperature of air near an air return port in a cooling room other than a room having a zone of lowest temperature to adjust the output of a heater based on the output from the sensor. SOLUTION: A temperature compensation heater 11 is mounted to or embedded in the interior or a wall surface of a room which vertically or laterally adjacent to a room having a zone of lowest temperature. As a result, a storage room 5 having a higher temperature zone than a vegetable room or a refrigerated room can be prevented from being excessively cooled. By setting a heater input control sensor 9 on an inner wall surface of the room 5 to control input values or ON/OFF of the heater, whereby air temperatures or wall surface temperature in the room 5, or temperatures of return cooling air entering a cooling air suction port 14 can be detected. Thereafter, the heater 11 takes into a CPU, in a refrigerator, signals of a heater input control sensor 9, outside air temperature sensor 12, and input signals of a cooling fan 2 to execute arithmetic operations, whereby the heater 11 is controlled.

摘要： PROBLEM TO BE SOLVED: To obtain a file system which exerts no influence on other terminals even when respective terminals operate data on a file server by managing the terminals sharing the data on the file server. SOLUTION: A logical layer management part 104 which relates a logical layer used for access from a user terminal to the hierachical structure of data files on the file server is provided on the user terminal 102. Consequently, the user terminal is able to access data without considering the hierarchical structure of the data files on the file server. On the user terminal (anywhere in the system), data position management tables 1201 to 1203 stored with the number of logical layers which were referred to are provided by data, and the tables are referred to when the data are accessed to prevent the storage capacity on the file server from being wasted owing to the repetitive storage of data and a logical layer having no reference destination from being generated.

摘要： PROBLEM TO BE SOLVED: To facilitate the repair of a freezing cycle, by expanding the end of the return pipe embedded in a heat insulating box, and arranging a decompressor wound in coil form in its inside, and taking out the decompressor from the connection to the return pipe in the vicinity of a compressor. SOLUTION: A decompressor 7 connected to the drier 10 at the outlet of a condenser is passed inside a return pipe 9 from a connection 9a on compressor side and a pipe joining pipe 9c, and is taken out from the junction 9b on the side of an evaporator, and is connected to the inlet pipe 8a of the evaporator. Then, the connection 9a on compressor side of the return pipe 9 and the suction pipe 5a of the compressor are expanded, and this refrigerator is provided with inner space which can accommodate the decompressor 7 in coil form, inside the return pipe joining pipe 9c for connecting the connection 9a on compressor side with the suction pipe 5a. Hereby, the length of the decompressor 7 and the pipe joining pipe 9c can be shortened, so the repair of the freezing cycle becomes easy.

摘要： PROBLEM TO BE SOLVED: To reduce operation costs by commonly utilizing program contents by transmitting MPEG(Moving Picture Experts Group) video signals while mutually connecting CATV networks more than two through a network using an internet protocol by an interwork means. SOLUTION: Concerning an MPEG-transport stream(TS), the case of transmitting a payload for storing data continuously to a TS header 1 of 4 bytes and the case of transmitting an adaptation field 2 before the payload are allowed. When transmitting a signal to an IP network, concerning the TS to transmit an IP header, the adaptation field 2 is inserted just after a TS header without fail and while using this adaptation field 2, the IP header is transmitted. The adaptation field 2 stores a flag 4 of 2 bytes showing contents to be transmitted and private data 5.
