摘要： PURPOSE:To detect a temperature rise precisely and perform an accurate charging control by arranging a temperature sensing element in a space part formed between three batteries or more. CONSTITUTION:Eight batteries 10 are built in a battery pack and five batteries 10 are arranged in the lowest stage of said battery pack in a state where they are adjacent to each other. An insulating sheet is stuck on the under surface of said five batteries 10 and between two batteries in the middle stage. A thermostat switch block B is arranged in a space part (a) formed by four batteries 10 out of the batteries 10 in the lowest stage. A temperature rise after the completion of charging of said batteries is sensed by said thermostat switch block B so that said charging is stopped, if necessary. A temperature sensor is little affected by an external temperature and a temperature scattering among batteries, because it is provided between batteries.

摘要： PROBLEM TO BE SOLVED: To ensure inexpensiveness and stably detect a biosignal under the less deterioration of the characteristics of components with the lapse of time. SOLUTION: This device is made up of a resilient body 2 having a surface subjected to a bio load, a support member 1 for bearing the resilient body 2, and light emitting element 4 laid on one of opposite surfaces of the resilient body 2 and the support member 1 as well as a light receiving element 5 laid on the other surface in a bio load application direction on the resilient body 2. A biosignal is detected from a change in the received light quantity of the light receiving element 5 on the basis of a distance fluctuation between the light emitting element 4 and the light receiving element 5. Thus, a change with the lapse of time does not take place, and stable signal detection is ensured, as the biosignal is detected on the basis of a spatial distance between the light emitting element 4 and the light receiving element 5, and no component is positioned between the elements 4 and 5.

摘要： PROBLEM TO BE SOLVED: To exactly detect a biological signal at all times. SOLUTION: In this biological signal detector, an optical fiber 2 for guiding light from a light emission circuit 1 to a light reception circuit 3 is arranged at the portion to which a bilogical load is transmitted through a living body supporting part, and the biological signal is detected from the change of the quantity of light to reach the light reception circuit 3 based on the fluctuation of the biological load. The plural parts of one optical fiber 2 are arranged at plural sections for supporting the various parts of the living body at the living body supporting part. Even when the load is small at the position holding a certain part of the living body, it can be supported at a position holding the other part so that the load fluctuation can be surely caught.

摘要： PURPOSE:To carry out accurate pulse measurement without being affected by the thickness change of an inspected portion which is due to the swing or the like of the inspected portion during movement, by providing a light emitting amount correcting means to control the light emitting amount of a light emitting element according to a light receiving level at a light receiving element. CONSTITUTION:When measurement is conducted by fitting a sensor portion to an earlobe which is an inspected portion, a light receiving level at a light receiving element 22 is low at the time of the earlobe being thick, that is, voltage VS is small, and a pulse waveform signal at a C portion is in the vicinity of a middle point, and the light emitting electric current of a light emitting element 21 is fixed by means of a transistor(Tr) Q2. Meanwhile, when the earlobe is thin and voltage VS becomes large and a DC element at the C portion becomes larger than the ON voltage of the middle point + TrQ3, TrQ3 becomes ON and the potential of the non-reversal terminal of an operation amplifier OP3 drops, so both end voltage of a resistor R9 becomes small, and the light emitting electric current becomes small, and a light emitting amount is made to drop, and when the DC element at the C portion becomes equal to the ON voltage of the middle point + TrQ3, the light emitting electric current is fixed.

摘要： PROBLEM TO BE SOLVED: To reduce restriction in mounting structure and cost with a compact designing in a highly sensitive device using an optical fiber. SOLUTION: In the living body signal detector, an optical fiber 1 which is arranged at a living body support part receiving a living body while guiding light from a light emitting part to a photodetecting part is deflected according to changes in the living body load on the living body support part to change the quantity of light to the photodetecting part and the living body signal is detected from an output of the photodetecting part. A load sharing member 5 is provided in contact with support members 7a and 7b for transmitting the living body load to the optical fiber 1 to share the living body load working on the support members 7a and 7b. The sharing of the living body load by the load sharing member 5 can reduce the load working on the optical fiber 1 itself.
