Title: Circuit of intermittent reception
Inventor: SUWA KEISUKE
IPC: H04W84/02
Filed: 1984-08-10
Abstract: PURPOSE:To prevent a transient current from flowing to a coupling capacitor through the intermittent power supply by amplifying a difference between a reception circuit output and an output voltage of a voltage divider at a differential amplifier to output a signal eliminating a DC component from the output of the reception circuit. CONSTITUTION:A waveform of an output 21 of the reception circuit is a rectangular wave from C around a voltage V2 at a period when a power is fed to the reception circuit 1, is 0 at a period when no power is fed to the reception circuit 1. On the other hand, the potential at a voltage division output terminal 25 is also V2 when a power switch 4 is turned on and 0 when the power switch 4 is turned off. Thus, a differential amplifier 7 amplifies only a portion corresponding to a digital signal in an output signal of the reception circuit 1 when the power switch 4 is turned on. No DC component appears at an output terminal 26 of the differential amplifier 7 but only the digital signal portion D appears, and then no transient charge/discharge current flows to the coupling capacitor 2, a signal waveform at a load terminal 22 is a digital signal E without distortion and a zero cross comparator discriminates accurately a signal.

Title: Method for diagnosing stomach cancer
Inventor: MIZUOCHI TSUGIO
IPC: G01N33/68
Filed: 1998-06-02
Abstract: PROBLEM TO BE SOLVED: To diagnose the presence/absence of a stomach cancer more highly accurately and more simply than by an X-ray inspection by using a gastric juice as a specimen and measuring a pH of the gastric juice. SOLUTION: According to this diagnosis method, a pH of a collected gastric juice is measured, thereby diagnosing the presence/absence of a stomach cancer. Since the gastric juice generally contains hydrochloric acid or the like in the components, the gastric juice of a healthy person or a person suffering from a gastritis shows an acidity of a pH of approximately 2.0-4.0, while the gastric juice of a stomach cancer patient is nearly neutral, i.e., a pH of approximately 6.0-7.5. Therefore, when a person has the gastric juice of pH of 6.0 or higher, the person highly probably suffers from a stomach cancer and is required to be inspected more accurately. The highly accurate inspection is preferably required when the pH is not lower than 5.0 so as to avoid a false negative judgment.  A pH measurement means is a known pH measurement method, e.g. a method using a pH test paper, a titration method with the use of a base, etc. This diagnosis method enables the inspection with a considerably higher accuracy and considerably simpler than an X-ray inspection. A burden of the patient is lightened and therefore this method is valuable for use in screening such as a group medical examination, etc.

IPC: A61B10/00
Filed: 1982-09-27
Abstract: PURPOSE:To return the direction of magnetization to a thermal equilibrium state within a short time, by predetermining the pulse system of an electromagnetic wave for inducing nuclear magnetic resonance. CONSTITUTION:The ON-OFF operations of a coil control circuit 2 for a magnetostatic field and a gate circuit 61 through which the output from an electromagnetic wave oscillator 6 is passed are controlled by a controller 30. When a Z-axis gradient magnetic field +Gz is applied to the corresponding coil and a 90 deg. pulse for exciting an object HB to be inspected is applied, the nuclear magnetic resonance signal from the surface Sz is detected. Subsequently, an 180 deg. pulse is applied at predetermined intervals under an X-axis gradient magnetic field and a Y-axis gradient magnetic field is further applied. In this case, when an (180-x') deg. pulse is applied under a Z-axis gradient magnetic field after an echo signal disappears and the Y-axis and X-axis gradient magnetic fields are applied succeedingly and successively while a 90 deg. pulse is applied under the Z-axis gradient magnetic field at the point of time when the echo signal becomes max., the direction of magnetization is forcibly directed to an X'-axis direction for bringing said direction to a thermal equilibrium state within a short time. Therefore, by repeating this cycle, a tomograhic image having good S/V and high resolving power is formed.
