Title: Distributed processing system
Inventor: NAKAZATO HIDENORI
IPC: G06F15/16
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To attain a distributed processing system capable of preventing a response time to the processing of a specific computer from being too much prolonged and efficiently operating the system itself. SOLUTION: A service information storing part 4 stores service description, a service providing program identifier(ID) and IDs of computers including a service providing program. A service allocation information storing part 7 stores the processing capacity indexes of computers and the value of an allocation counter indicating whether several service providing programs are permitted to be executed or not in response to the IDs of the computers. When a service retrieving request is outputted from a service use program, a service retrieving part 5 extracts the IDs of computers including the service providing program. A service allocation part 6 outputs a computer having the minimum processing capacity index/allocation counter value as a retrieved result out of the computers extracted by the retrieving part 5.

Title: Camera capable of switching picture size
Inventor: TSUYUKI HIROTO
IPC: G03B17/18
Filed: 1998-07-06
Abstract: PROBLEM TO BE SOLVED: To issue a waning when panoramic size coexists in standard size at the time of finishing photographing. SOLUTION: The number of taken photographs of standard size, the number of taken photographs of panoramic size and switching frequency by a picture switching means 5 are stored in a storage means M by a control circuit 1b equipped with a counting means counting these numbers. When a film rewinding button R is actuated and a signal is outputted to a CPU, the warning such as a sound is issued from a warning means 21 when the picture size coexists. Since not only the numbers of the taken photographs of the standard size and the panoramic size are grasped but also whether the picture size is only the standard size or the panoramic size coexists in the standard size is discriminated and grasped, a charge at the time of developing and printing is predicted, which is convenient.  Besides, a mistake in sticking seals showing all panoramic sizes/ coexistence of panoramic sizes at the time of printing a film is reduced.

IPC: F02M55/02
Filed: 1997-07-16
Abstract: PROBLEM TO BE SOLVED: To prevent the sliding motion of electric contacts in a fuel injector and suppress a deterioration in the fuel sealing performance of the injector between its delivery pipe and injector. SOLUTION: A fuel injection system comprises a delivery pipe 7 provided with a connector 34, and an injector 8 provided with an O ring 52 and an injector-side terminal 54 and attached to the pipe 7.

Title: Pulley mechanism
Inventor: OKA TAKASHI
IPC: F16H55/36
Filed: 1982-10-30
Abstract: PURPOSE:To aim at preventing an endless belt from coming off and as well preventing torque loaded to a pulley for endless belts or the like from increasing, by supporting the pulley at one end to a support shaft and the other end to a ball bearing, and by forming a belt receiving groove in the pulley in the bearing supported end part thereof. CONSTITUTION:A pulley 1 is supported to a support shaft 5 at its one end through a ball bearing 6 and its the other end directly to the support shaft 5. A belt receiving groove 4 is formed in the pulley on the side of the fitted ball bearing 6. In this arrangement, the distance (a) between the center of the ball bearing 6 and the center of the bottom plate of the pulley 1 is set to be remarkably greater than the distance (b) between the center of the ball bearing 6 and the plane extending through the flange edge 3 of the pulley 1 near to the opening end of the latter. With this arrangement, the flange edge 3 prevents a belt 7 coming off, and, even if tension is concentrated to the flange edge 3, the force WXb/a which is exerted to a hole 2 may be made small since the value of b/a is small, thereby loading torque upon rotation may be prevented from increasing.
