Title: Reverse revolving machine for vessel
Inventor: OTSUKI KAZUHIKO
IPC: F16H3/14
Filed: 1986-07-11
Abstract: PURPOSE:To revolve a propeller shaft at an equal speed both in advance and retreat of a vessel by meshing the gear train of a reverse revolution system through the meshing between the cylindrical gears and making the gear ratio of the reverse revolution system equal to the gear ratio of the gear train of a normal revolution system. CONSTITUTION:When a vessel advances, the engine power is transmitted to a propeller shaft from an input shaft 15 through a cylindrical gear 22 on the input shaft, conical gear 23 on an output shaft 16, and the output shaft 16. In retreat, the engine power is transmitted to the propeller shaft from the input shaft 15 through the conical gear 22 on the input shaft 15, cylindrical gear 25 and other cylindrical gear 26 on an intermediate gear 17, cylindrical gear 24 on the output shaft 16, and the output shaft 16. Therefore, the gear ratio of a gear train in the normal revolution system and the gear ratio of a gear train in the reverse revolution system are made equal each other, and the propeller shaft is driven in the substantially equal number of revolution both in the advance and retreat of the vessel.

IPC: G06F9/48
Filed: 1979-12-18
Abstract: PURPOSE: To ensure the state of CPU, by performing the write-in to the stack produced from the production of interruption through switching it to exclusive use register group provided on the system newly.  
     CONSTITUTION: When an interruption request 5 is produced, flip flop E is inverted, and the write-in signal 3 to the entire system is inhibited with this inversion by an AND gate B, and the writen-in signal 4 after that is fed to the stack register F from the AND tage A. Further, the request 5 enables the supply of the count signal to the N notation counter D with the AND gate C and performs n times count for the write-in operation to the memory of CPU. Further, the register value and the value of stack pointer are output to the address bus 2 and the data bus 1 every write-in operation once, and one of the registers F is selected with the decoder G to write in the value on the bus 1. Further, when the n times write-in operation is finished, the flip flop E again inverts with the carry signal of the counter D, the request 5 is released with the release signal 6 and the write-in signal 3 of the entire system is returned to the original state.
