Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To reduce torque loss due to a bearing, and also shorten a rotor shaft, by providing a deep groove ball bearing on one end side of one side rotor shaft, also a cylindrical roller brearing on the other end side, and equipping a means for adding pretension in a direction same as that of a thrust load supported by the deep groove ball bearing. SOLUTION: In bearing a rotor shaft 1 such as an aircraft gas turbine, one cylindrical roller bearing 3, suitable for a heavy load and high-speed rotation, is arranged on a given place on the counter-joint side of the rotor shaft 1, and one deep groove ball bearing 2, for supporting a thrust load in high-speed rotation is arranged in a given place on a joint side. Pretension, for pulling the rotor shaft 1 in an axial direction, is added to the rotor shaft 1 to load the deep groove ball bearing 2 with a radial load and one-way thrust load. That is, a diaphragm type coupling is fitted to the end of the rotor shaft 1, and pretension in the axial direction is given to an intermediate shaft 5 previously by the spring 6 of the diaphragm type coupling, thereby setting the deep groove ball bearing 2.

Title: Electronic equipment
Inventor: MATSUMOTO SHIGEO
IPC: G06F1/00
Filed: 1988-07-08
Abstract: PURPOSE:To attain an automatic resetting action of a CPU by producing a resetting signal from a counter when an output signal is latched up by a runaway. CONSTITUTION:An optional output port which can obtain an output signal having the variance of its level in an interval smaller than a prescribed time interval of a CPU 1 is connected to a clear terminal of a counter 3 via a differentiating circuit 2. At the same time, the output of a clock generating circuit 4 is connected to a clock terminal of the counter 3. Then a carry output is taken out when the count value of the counter 3 reaches the numerical value equivalent to a prescribed time interval. When the software has a runaway, the signal of the output port is latched up at a high or low level. Therefore no detecting signal is obtained from the circuit 2 and the counter 3 is not cleared. Thus the carry output is taken out after a prescribed time interval and supplied to a resetting terminal of the CPU 1. As a result, the CPU 1 can be reset from the runaway state.

Title: Subscriber circuit
Inventor: HIBINO SATORU
IPC: H04Q3/72
Filed: 1986-07-18
Abstract: PURPOSE:To contrive to keep a two-wire side impedance to be constant without the aid of an ON/OFF by detecting the ON/OFF of a subscriber loop by means of a state detection circuit and providing a capacitor and a resistor which are connected in series with a switch to be controlled by the output of the state detection circuit. CONSTITUTION:A transmitter amplifier 12 and a receiver amplifier 14 are connected to a two-wire/four-wire converter circuit 4, and the circuit 4 has a balance network 13 which is approximately equal to the two-wire side impedance, e.g. the composite impedance of a telephone set 1 being in OFF hook state and a subscriber line 2. The state detection circuit 15 detects the ON/OFF state of the subscriber loop, and at the time of an ON hook state, it generates an output, drives a transistor 17 and operates a relay 18. After the relay 18 operates, the contact 18-1 of the relay closes and the capacitor 19 and the resistor 20 are inserted between a two-wire system line 2. The capacitor 19 prevents the resistor 21 from the flow of a direct current, and simultaneously, being combined with the resistor 20, keeps the impedance of the line 2 to be equal to a value of that in the OFF hook state.

Abstract: PURPOSE:To provide the capability of coping with internal pressure by forming a shear resistance section such as ribs staggered along the peripheral direction of lining, on the ring joint surface between segments, and filling the gap of the jointed surface with a filler for jointing the segments to each other. CONSTITUTION:In space inside the skin plate 20 of a shield machine, synthetic segments 1A are held with an erector and supported on a mobile timbering device 21.
