Title: Hardening method for outer ring of constant speed universal coupling
Inventor: HOSOKAWA MANABU
IPC: F16D3/2245
Filed: 1979-10-31
Abstract: PURPOSE:To perform hardening at a low cost by utilizing high frequency energy effectively, by  pressing the top end of the legs of a heat-absorbing material to the end surface of the outer ring  of a constant speed universal coupling at the part near the guide grooves, then by induction  hardening the contact surface of the cage and the guide grooves. CONSTITUTION:The outer ring 10 of a constant speed universal coupling is positioned at a prescribed angular phase. Projected legs 22 made of good heat-conducting material are mounted on  a base 21 at an equal distance apart from the guide grooves 12 of the outer ring 10 to form a  heat-absorbing body 20. With the angular positions of the guide grooves 12 of the outer ring 10  being coincided with the angular positions of the legs 22 of the heat-absorbing body 20, the heat-absorbing body 20 is moved forward thereby engaging the top surfaces of the legs 22 with  the end surface of the outer ring 10. Then a high frequency electric source 24 is operated so as to  heat the internal peripheral surface of the outer ring 10. After completion of said heating, cold  water is sent pressurized into a heating coil 23 in order to quench the internal peripheral surface of the outer ring 10, hereby hardening is completed. This method allows to prevent the high frequency energy radiated from the heating coil 23 from being absorbed by the heat-absorbing body  20.

Title: Steam turbine control device for combined power plant
Inventor: UCHIDA NORIHIRO
IPC: F01K23/10
Filed: 1991-05-17
Abstract: PURPOSE:To protect turbine blades by detecting an opening degree of an exhaust heat inlet damper and by calculating a limited opening degree for a steam adjusting valve in accordance with the result of the detection so as to rapidly close the steam adjusting valve when the exhaust heat damper is closed. CONSTITUTION:A low value selector 20 receives an output signal which is obtained by adding an output signal from a speed controller 16 to an output signal from a load controller 17, and an output signal from a load limiter 18 and an output signal from a steam controller 19. Further, the selector 10 selects a signal having a lowest value among these signals and delivers the same as a man steam control value opening degree setting signal. In this arrangement, a function generator 21 and a variation rate limiter 22 are further provided. When an opening degree signal from an exhaust heat inlet damper is, for example, decreased, an abrupt decrease command is delivered from the function generator 21 which receives the opening degree signal, to the low value selector 20 by way of the variation rate limiter 22. Accordingly, the main steam control valve is closed to prevent the steam pressure of the inlet port of the steam turbine from abrupt decrease.

Title: Linearizing device
Inventor: MASUDA KOICHI
IPC: H04B10/2507
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To cancel a distortion component based on the non-linearity of a signal processing circuit by simple constitution without executing complicated adjustment. SOLUTION: A designer or the like grasps the I/O function of an amplification part 13 and executes adjustment so that the I/O function of an amplification part 11 approximates to that of the amplification part 13. In the case of amplifying an input signal, the amplification part 11 superposes a secondary harmonic distortion component based on the non-linearity of the I/O function to a main signal and outputs an amplified signal. A phase inversion part 12 receives the amplified signal outputted from the amplification part 11, inverts the phase of the received signal and outputs the inverted signal to the amplification part 13. In the case of amplifying the input signal, the amplification part 13 superposes the secondary distortion component to the main signal.  The secondary distortion component superposed by the amplification part 13 is consequently canceled by a secondary higher harmonic distortion component of reverse polarity inputted from the phase inversion part 12.

IPC: G01R19/165
Filed: 1990-05-31
Abstract: PURPOSE:To reduce the electric power loss of a resistor provided on a DC path so as to improve the operating efficiency of the title device by applying a voltage generated across a bias means across the light emitting element of a photocoupler, with the voltage being superimposed upon a voltage generated across the resistor. CONSTITUTION:A resistor R11 and diode D12 are added to the emitter of a large-power transistor constituting a main circuit. The resistor R11, diode D12, and a diode serial circuit D11 are connected in series to a DC power source VDD. The value of the DD resistor R11 is selected so that the end-to-end voltage of the circuit C11 does not change even when the resistor R11 and diode D12 are added. The diode D12 always generates a constant voltage and supplies the voltage to a light emitting diode ED constituting a photocoupler 8. Therefore, the resistance value required for detecting an excessive current on the main circuit is reduced and the power loss of this excessive current detecting device can be suppressed as compared with the conventional excessive current detecting device.
