Abstract: PURPOSE:To operate the absolute value of a difference between two signals at a high speed only by one instruction by providing the titled unit with an arithmetic logical circuit for executing the logical operation and addition/ subtraction of two input signals, a subtractor for executing prescribed subtraction and a selecting circuit for selecting the outputs of both the circuits. CONSTITUTION:Input signals A, B are inputted from input signal lines 11, 12 respectively. When an absolute value arithmetic mode is determined by an instruction signal line 13, an arithmetic logical block 1 is set up to a subtraction mode and a difference A-B is outputted to a signal line 14. On the other hand, a difference B-A is outputted to an output side signal line 15 of the subtractor 2. The selecting circuit 3 executes the following operation. At first, the code of the subtracted result A-B outputted to the signal line 14 is decided. In case of 2's complement display, a maximum bit '0' shows a positive and a maximum bit '1' shows a negative. The maximum bit is decided and the signal A-B or B-A is outputted to an output signal line 16 in case of '0' or '1' respectively. Namely, when the A-B is a positive, an output D becomes A-B, and in case of a negative, B-A is outputted. Since ¦A-B¦=¦B-A¦, a positive value, i.e. ¦A-B¦, is always outputted to the output D.

Title: Axial-flow turbine
Inventor: NAKANO TAKESHI
IPC: F01D25/30
Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To eliminate a swirl inflow component without increasing loss due to swirl by providing a guide blade of an obtuse head shape in a passage of a diffuser of an axial-flow turbine formed in the downstream side of a rotor blade. SOLUTION: A plurality of obtuse-head shaped guide blades 10 are provided in a diffuser passage 9. Obtuse head shape refers to a streamline shape in which an end portion located in the upstream side is rounded loosely in a sectional shape of the guide blade 10 and narrows toward a rear end portion. By loosely rounding the end portion of the guide blade 10, resistance against slanted flow is reduced as compared to that with a sharp end portion of the guide plate, and generation of swirl is prevented around the end portion to smoothly change the swirl into axial flow which is introduced into an annular diffuser 5. Then, a flow speed of the axial flow so as to be reduced in the annular diffuser 5, and a pressure of gas fluid is increased.  The obtuse head shape of the guide blade 10 prevents loss caused by resistance of the guide blade 10 itself and eliminates swirl inflow component without increasing the loss.

Title: Axial piston machine
Inventor: ITOU YOSHIMITSU
IPC: F03C1/28
Filed: 1984-07-05
Abstract: PURPOSE:To aim at preventing seizure and damage between both circumferential surfaces from occurring, by forming a curvature center of a spherical surface of a piston hear part so as to be situated in a position inside a cylinder all the time at the time of its reciprocation, while constituting an outer circumferential surface of the piston so as to press an inner circumferential surface of the cylinder with uniformly distributed force. CONSTITUTION:In a spherical 23 forming a spherical head part of each piston 8, its curvature center O is formed so as to be situated in the more rearward then a front end part 24 of a cylinder block 6 even in a state that the piston 8 is mostly projected from the cylinder block 6. With this positional constitution, force F acts on the piston 8 from a swash plate 11 in a direction of the curvature center O of the spherical surface 23 whereby if lateral force f is produced there, this lateral force f occurs inside a cylinder 7 so that such moment as rotating the piston 8 as in the past is in no case produced, and it acts on as uniformly distributed force for pressing an outer circumferential surface of the piston 8 to an inner circumferential surface of the cylinder 7. Therefore, seizure and damage between both circumferential surfaces aforesaid are kept back, and the leak and pulsation of a hydraulic fluid are preventable from occurring, thus durability in a machine is well improvable.

Abstract: PURPOSE:To float the entire body of a tape from a rotary cylinder and, at the same time, to stably run the tape without leading the tape, by making the barrel section of the rotary cylinder longer and giving a prescribed diameter difference between its upper and lower parts. CONSTITUTION:The barrel section of a rotary cylinder 15 is formed longer so that it can reach the vicinity of the base of a fixing cylinder 16 and the cylinder diameter at the upper part is made larger than that at the lower part in the vicinity of the recording and reproducing head fitting height. A recording and reproducing head 4 is fitted to the rotary cylinder 15 so that a prescribed quantity of the head 4 can be projected from the opening 17 of the cylinder 15. As a result, a tape can be run under a condition where the tape is wound around the barrel section of the cylinder 15 and around a rotary head assembly with an air film between the tape and assembly. By chaning the diameter of the barrel section in such a way, a downward component of force is applied to the tape and, on the othr hand, force moving the tape upward is always applied to the tape from the contact between the head projected from the rotary cylinder 15 and the tape. Therefore, the tape can be run stably without leading the tape, when the diameter difference is properly selected so as to balance the two force with each other.
