Title: Detecting method of magnetism
Inventor: SEGUCHI SHUJI
IPC: G01R33/02
Filed: 1993-12-14
Abstract: PURPOSE:To cause magnetization directed variously in an initial state to show the same state of magnetization and to enable attainment of a reproducible output by a method wherein a current of a value saturating the magnetization temporarily or above is made to flow and then restored to a constant current of a value at which the magnetization is unsaturated. CONSTITUTION:Magnetization in a ferromagnetic substance is not uniform in the direction in an initial state. In a state wherein a current of a value saturating the magnetization temporarily or above is made to flow through a coil 2a or 2b (at the time of transition), the magnetization is saturated in the direction of a composite magnetic field of a bias magnetic field generated by the coil 2a or 2b and geomagnetism. When the current is restored thereafter to a current of a prescribed value at which the magnetization turns unsaturated (at the time of a constant current), the magnetization directed variously in the initial state shows the same state of magnetization. Therefore a reproducible output can be obtained.

Title: Semiconductor integrated circuit device
Inventor: SUZUKI MASAHIRO
IPC: H03K19/0948
Filed: 1989-12-01
Abstract: PURPOSE:To reduce a through-current flowing at the time of changing a signal by setting threshold voltages of P and N-channel transistor(TRs) between the output change voltage of an inverter element and 2nd and 1st power supply potentials, respectively. CONSTITUTION:When the potential of a signal shown in figure A is a 1st power supply potential, the signal of a 2nd power supply potential is supplied to the input of an inverter of a final stage through two inverters placed in parallel, a P-channel TR 1 is turned on and an N-channel TR 2 is turned off and the signal of a 1st power supply potential is outputted as shown in figure B. When the potential of a signal shown in the figure A changes from the 1st power supply potential to the 2nd power supply potential, since the signal of the 1st power supply potential enters the input of the inverter of the final stage from the 2nd power supply potential, the signal shown in figure B changes from the 1st power supply potential into the 2nd power supply potential. In such a case, since threshold voltages (VTHP, VTHN) of the P-channel TR 1 and the N-channel TR 2 are set respectively as shown in figure, the simultaneous ON state at the signal change is evaded.

Title: Chlorine ion sensitive film and electrode
Inventor: YAMASHITA KOTARO
IPC: G01N27/333
Filed: 1990-11-21
Abstract: PURPOSE:To maintain the electrode operating performance for a long period of time in practical use by using class-4 ammonium salt to an ion exchanger, and introducing F atoms to an organic radical which tends to form a bond with N atoms. CONSTITUTION:An electrode cylinder 1 is filled with an internal solution 2, and therein an internal electrode 3 is immersed. An ion sensitive film 4 is fixed to the end of the electrode cylinder 1. When class-4 ammonium salt is used as an ion sensitive substance for this electrode, elusion of ion sensitive substance from this sensitive film 4 is decreased which otherwise results in inferiority in the long-term stability to a certain degree, and therefore, fat solubility of ammonium salt shall be increased. Therefore, self-machine radicals (H atom) X, Y, Z, U forming a bond with the sensitive film 4 having alkyl chain are substituted with F atoms having a large atomic radius. Accordingly increasing the volume of class-4 ammonium salt molecles themselves will be hydrophibic, to cause increase in the fat solubility, and elusion of the ion sensitive substance from the sensitive film 4 will lower. Thus long-term stability of the electrode operating performance is obtained.
