Patent JP-H10227893-A (JP)
Title: Metal corrosion prevention method
Inventor: TACHIBANA MASAHIKO
IPC: G21D1/00
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To physically control the oxygen concentration in coolant and suppress stress corrosion cracking of stainless steel without owing to injection of medicines and the like by using solid electrolyte and directly operating the oxygen concentration in liquid contacting metal. SOLUTION: Solid electrolyte, for example zirconia 1, is heated by impressing voltage to a heating means 3 isolated with an isolation means 4 using a voltage adjusting means 6 and voltage is impressed between 2a and 2b with a voltage control means 5. Electric field is generated inside the zirconia 1 so that oxygen concentration difference can be generated with the boundary of the zirconia 1. That is, with the boundary of the zirconia 1, the oxygen concentration in a liquid contacting the cathode is reduced to increase that in liquid contacting anode. Therefore, by contacting and passing the electrode 2a coolant contacting the metal having problem of high oxygen concentration, the oxygen concentration in the coolant is lowered and thus, corrosion due to oxidation or stress corrosion cracking of stainless steel can be suppressed.

Title: Motor rotation presence/absence detector
Inventor: YOMOGIHARA KOICHI
IPC: H02K11/00
Filed: 1993-02-19
Abstract: PURPOSE:To obtain a motor rotation presence/absence detector in which presence/absence of rotation of a motor can be detected in a fail-safe manner by providing an on-delay circuit for outputting an output from a window comparator by delaying it for a predetermined period. CONSTITUTION:A motor M is connected to an AC power supply through a switch circuit 1, and a snubber circuit 2 is connected in parallel with the motor M through a primary winding of a transformer T1. It is monitored with the transformer T1 for connecting a primary winding N1 to the circuit 2 and a bridge circuit 3 having a secondary winding N2 of the transformer T1 as one side, its unbalanced output signal is amplified, rectified and then an output signal of a rectifier circuit REC1 is level-detected by a window comparator 5. As a result, a motor rotation stop detection signal is not output from the circuit 6 at the time of rotating the motor M by conducting and idling by inertial force without conducting, and it is output only at the time of substantially stop state, and hence presence/absence of the rotation of the motor M can be detected in a fail-safe manner.

Title: Optical head
Inventor: KOBAYASHI SHIYOUHEI
IPC: G11B7/135
Filed: 1995-02-20
Abstract: PURPOSE: To prevent the degradation in the amplitude of a reproduced signal by nearly equally separating the light rays in the original polarization direction to ordinary ray and extraordinary rays by an analyzer. CONSTITUTION: The analyzer 7 is formed of an optical member having uniaxial double refraction. The plane on which the return light of the analyzer 7 is made incident is defined as an x-y plane and the direction normal to this plane as a z-axis. The x-y-z coordinate rate xyz at which the optical axis of the return light progresses in the z-x plane and both of the x-component and z- component of the progressing direction of the optical axis of the return light attain positive is defined. θ is defined as the angle formed by the optical axis of the return light and the z-axis, δ as a constant within a range of 44 to 46 deg. and -44 to -46 deg. and α and β are defined as variables independent from each other. At this time, the optical axis of the analyzer 7 is characterize to be lying in the plane parallel with the plane expressed by the equation.  The difference in the light intensity of the ordinary rays and extraordinary rays is thereby maximized when the return light rays rotated in the polarization direction are separated to the two kinds of rays by the Kerr effect. The degradation in the amplitude of the reproduced signal is thus averted.

Filed: 1994-03-01
Abstract: PURPOSE:To improve operability by requesting the change of transmission/reception timings from a remote controller to an equipment when no response is present from the equipment even when the fixed same number of signals are outputted from the remote controller. CONSTITUTION:When a synchronization timing accidentally coincides with the other equipment, the communication of the remote controller 2 and a gas hot water supplier 6 can not be performed. When a remote control communication equipment 7 can not perform reception even when data from the main body communication equipment 1 of the hot water supplier 6 are transmitted to the remote control communication equipment 7 of the remote controller 2 for four times for instance, the equipment 7 transmits a remote control transmission/reception timing change request to the equipment 1. When the equipment 1 receives the request signal, a transmission/reception timing adjustment device 9 changes the transmission/reception timing. For instance, the timing for performing transmission/reception until then is shifted for two seconds, the equipment 1 transmits the signals to be transmitted/received to the equipment 7 and the transmission/reception of the equipment 7 of the remote controller 2 with the equipment 1 of the hot water supplier 6 are performed at the changed transmission/ reception timing thereafter. Thus, the communication is smoothly performed.
