Title: Depth finder
Inventor: MORI HIDEKI
IPC: G01F23/00
Filed: 1989-10-11
Abstract: PURPOSE:To accurately measure a depth from a reference position to a surface to be measured by extending a wire until a weight reaches the surface, stopping the descent of the weight by detecting the fluctuation of a balance and measuring the length of the extended wire. CONSTITUTION:A depth finder 1 is mounted to the upper portion of a tank. A driving motor 13 is operated, a weight 2 is let descend and, at the same time, a measurement by measuring means (the encoder of a pulse generator) 8 is initiated. At this time, a balance 5 is horizontally held. When the weight 2 reaches a surface to be measured and sinks a little into the surface, a resultant buoyancy reduces a weight applied to a wire 3 and destroys the balance of the balance 5. Therefore, the balance weight 25 side of the balance 5 descends and an electric detector 7 is closed to open the circuit of the motor 13, being stopped. At the same time, the measurement by the measuring means 8 is terminated and an arithmetic circuit 33 calculates and displays the length of the extended wire 3 from the number of pulses applied from the measuring means 8. In this case, the lower end of the weight 2 is positioned below the surface to be measured by a little distance and this distance is determined by an experimental value in advance to be inputted to the circuit 33 as a correcting value.

Title: Method and device for controlling command issueing
Inventor: ACHIWA KIYOUSUKE
IPC: G06F13/12
Filed: 1998-09-21
Abstract: PROBLEM TO BE SOLVED: To prevent a device having the function of command queuing from receiving a lot of commands. SOLUTION: The number of commands, for which issue is completed but the end is not reported, to the device having the function of command queuing is counted. When issuing a new command, the said number of commands is compared with the number of inflow limits. If the said number of commands is less than the number of inflow limits, the said new command is issued, but if the said number of commands is not less than the said number of inflow limits, the said new command is not issued (step 526). Thus, concerning the device having the function of command queuing, occurrence of overhead to return a lot of busy is prevented. Therefore, this device can be concentrated in original processing to commands so that processing efficiency is improved.

IPC: F16C13/00
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To effectively inhibit or prevent the generation of noise in the cool, while keeping the function as a pulley, by comprising a pulley body, and a cage of a ball bearing which is fitted to the pulley body and has pockets for accommodating the balls in a peripheral direction at unequal pitches. SOLUTION: In a cage 2d of a bearing, the pockets which have been formed at equal pitches in a conventional cage, are arranged at unequal pitches (unequal arrangement cage). A number of kinds of angles of circumference θ between pockets (an angle between the center lines P1 , P2 of the pockets adjacent to each other), can be arbitrarily determined so long as it is not less than 2. By unequally arranging the pockets 3, the balls are not rotated on the same route, so that even when a part of balls are channeled off by the grease on a transfer face, the other balls are passed through over the grease, whereby the abnormal vibration of the balls caused by the damping action of the grease can be prevented. As mentioned in the above, the structure is simple, so that it is also effective in view point of the cost.
