To conduct the stimulation by detection of the electrocardiogram, when an electrocardiogram signal is inputted from the input part 4 to the judgment means 2, the time phases of the contracting period and expanding period are detected from the electrocardiogram signal. In the expanding period, pulses are outputted from the judgment means 2 toward the switching means 3 to close the switching means 3, and a stimulation output outputted from a low frequency stimulation output means 1 is applied to the living body through the conducting element 5. Consequently, the circulation of blood is accelerated, and the stiffness of the shoulders and various troubles accompanied by the reduction in living body activities can be conquered.

IPC: G01N27/447
Filed: 1988-01-29
Abstract: PURPOSE:To enable migration always at a constant temp. so that data having reproducibility is obtd. even if thermal environment changes by directly detecting the temp. of the gel medium itself and controlling a high-voltage power supply in accordance with the signal corresponding to the detected temp. CONSTITUTION:The permissible range of the migration temp. is first set and the migration temp. is monitored via a thermocouple 4 by a CPU 8 which monitors both of the high-voltage power supply 7 and a cooling block 2. The voltage is raised until the upper limit of the migration temp. is attained if said temp. is in a permissible range. The specified voltage is maintained until the heat diffuses and the same temp. as the cooling temp. is attained upon attaining of the upper limit. This operation is repeated until the upper limit of the voltage impression is attained and thereafter the specified voltage is maintained. The voltage is once lowered and after the state stabilizes, the voltage is again raised up to the upper limit of the impression if the upper limit tem. is exceeded in the constant voltage state. The migration is thereby effected always in the constant temp. state and the data having the reproducibility is obtd. even if the thermal environment changes.

Title: Fuel injection timing control device for internal combustion engine
Inventor: OTSUKA IKU
IPC: F02D41/34
Filed: 1994-02-18
Abstract: PURPOSE:To prevent worsening of drivability by a method wherein a fuel injection timing is gradually advanced when the fuel injection timing is switched from suction synchronism to suction non-synchronism. CONSTITUTION:When a cooling water temperature is detected by a cooling water temperature sensor 11 and it is decided that a current time is before warming up of an engine, suction synchronism being a fuel injection starting period is decided taking a fuel injection completion timing, the present number of revolutions of an engine, and a valve opening time into consideration and most of fuel is injected during opening of a suction valve 4. When a cooling water temperature is increased and it is decided that a current time is after warming up of an engine, it is decided whether a crank angle at a preceding fuel injection completion timing is below that right before opening of a suction valve 4. In the decision, switching is effected when a fuel injection timing approaches a fuel injection completion timing being suction non- synchronism, taking a fuel injection completion timing, the present number of revolutions, and a valve opening time into consideration. Since, during the switching, a fuel injection timing is gradually advanced and a fuel amount is gradually increased, quantities of fuel is not adhered to a suction passage 5 at one time, and a desired air-fuel ratio can be realized.
