IPC: F16H48/12
Filed: 1991-02-22
Abstract: PURPOSE:To provide a rotation transmitting device possible to mechanically conduct the transmission and change of a driving torque and control the transmitting direction of the torque only in one direction. CONSTITUTION:Engaging surfaces 4, 5 are formed on the opposed surfaces of an outer ring 1 and an input shaft 2, and a sprag 9 engaged with the engaging surfaces by the relative rotation between the input shaft 2 and a retainer 6 and an elastic member for holding the sprag in neutral state are integrated into the pocket of retainers 6, 7 provided between both the engaging surfaces. The retainer 6 and the input shaft 2 are connected to a control shaft 12 through pins 15, 17, a rotating directional clearance is provided in the connecting part between the pin 17 and the input shaft 2, and a deceleration force giving means 19 for decelerating the rotation of the control shaft 12 is connected to the top end of the pin 17. When the input shaft 2 is rotated, the control shaft 12 is rotated later than the input shaft 2 by the clearance portion of the connecting part, and the sprag 9 is laid in engaging operating state by the relative movement of the retainers 6, 7. When the rotation of the outer ring 1 is faster than the input shaft 2 in this state, the outer ring is overrun, and in the reverse case, the sprag is engaged with the engaging surfaces to transmit the torque to the outer ring.

Title: Gain control circuit
Inventor: SAWAMURA HIDEHIKO
IPC: H03G3/12
Filed: 1986-02-14
Abstract: PURPOSE:To control the gain without changing an emitter bias current by causing a constant current to flow dividedly to a current path including a variable resistive element and the other current path by means of a differential circuit and connecting two kinds of current paths to the emitter. CONSTITUTION:A common emitter amplifier circuit consists of a transistor (TR) 1, a variable resistive element 5, and a resistor 7. The DC bias component in the emitter current of the TR 1 is divided differentially by TRs 2, 3 and the emitter current is decided by a TR 4. The input signal is amplified by the TR 1 and the signal component is blocked by an inductance 6 at the emitter side of the TR 1, then the gain depends on a ratio of a collector resistor 7 to an AC resistance of the variable resistor element 5. The DC bias current flowing to the TR 1 being the sum of currents flowing to the TRs 2, 3 is set by resistors 12-14 of the TR 4 by changing a DC bias current flowing to the variable resistive element 5 by means of the control voltage.

Title: Single body double water path combustor
Inventor: SAITO TOSHIHISA
IPC: F23N5/00
Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To detect leakage of hot water automatically during independent operation of additional heating. SOLUTION: A hot water supply heat exchanger 2 is integrated with an additional heating heat exchanger 3 and provided with a section for detecting the flow rate of a circulation channel 23 based on the temperature detected by a sensor 31 for detecting the hot water temperature of the heat exchanger 2 utilizing the phenomenon where heat is absorbed from the hot water supply heat exchanger 2 side to the additional heating heat exchanger 3 side by hot water circulating through the heat exchanger 3 and the quantity of heat to be absorbed depends on the flow rate of hot water circulating through the heat exchanger 3. Since heat of the heat exchanger 2 is absorbed not only to the heat exchanger 3 but by the leakage hot water upon occurrence of hot water leakage, a hot water leakage signal is delivered when the maximum circulation flow rate is exceeded.

Title: Suppressing or attenuating method and device for undersired spectrum in dynamic elongation of digitalized compressed signal
Inventor: HAINTSU GETSUKURAA
IPC: H03H17/00
Filed: 1990-02-13
Abstract: PURPOSE: To suppress or damp an undesirable spectrum at the time of performing digital dynamic elongation by using a sampled frequency which is higher than that at the time of performing the subsequent digital processing on elongated signals. CONSTITUTION: Compressed analog signals are converted into digital signals at a frequency fA' higher than a normal sampled frequency fA and the digital signals are elongated at the raised sampled frequency fA'. The signals elongated at the raised sampled frequency fA' are supplied to a decimation filter DF from the output side AO of a dynamic expander EXP. The filter DF lowers the sampled frequency fA' to the normal sampled frequency fA used for the subsequent processing of the digital signals. Therefore, a defective non-harmonic spectrum can be suppressed or damped.
