Abstract: A biosensor comprises a space part for sucking and housing a sample formed of two upper and lower plates, the two plates being stuck together by an adhesive layer, the space part for sucking and housing the sample being constituted so as to be partially opened in the peripheral part and partially closed by the adhesive layer, and has a working electrode having at least glucose oxidase immobilized thereon and a counter electrode on the same plane of the plate.

Abstract: To adapt to the relative small sizes of portable electronic devices, two battery output terminals of rechargeable batteries are frequently deployed in a close vicinity to each other. Consequently, rechargeable batteries are prone to cause output terminals short. To prevent such output terminals from shorting, a switching circuit and an activating signal generating circuit are deployed between a rechargeable battery and a pair of voltage output terminals. In response to an activating signal generated by the activating signal generating circuit, the switching circuit connects the rechargeable battery to the voltage output terminals. In absence of an activating signal, the switching circuit disconnects the rechargeable battery from the voltage output terminals, so that a short of the output terminals will not occur to the rechargeable battery even if the voltage output terminals are directly connected with each other.

Abstract: A radio receiver capable of receiving world wide shortwave broadcasting programs is constructed of a phase-locked loop circuit, a standard time generating circuit, a memory, a timer unit, and a controller. The phase-locked loop circuit includes a frequency dividing circuit and performs a frequency conversion of a received signal by changing a frequency dividing ratio of the frequency dividing circuit. The standard time generating circuit counts the Greenwich standard time. A shortwave broadcasting service area is subdivided into a plurality of service ares based upon time difference data corresponding to the Greenwich standard time produced from the standard time generating unit. The memory stores therein a plurality of frequency data receivable within an area of the plural set areas. The timer unit counts local time obtained by correcting the Greenwich standard time derived from the standard time generating unit based on the time difference data from the memory.

Abstract: A double super-heterodyne receiver has a high-frequency input circuit that includes a high-frequency amplifying device, a low-pass filter and a high-pass filter used for obtaining bandpass characteristics for the receiving band. A switching device for changing the cut-off frequency of, at least, the low-pass filter is further provided for the high-frequency input circuit. The switching device is controlled to be on or off in response to the receiving frequency, thereby changing the passband of the high-frequency input circuit. Image disturbance characteristics can thus be improved.

Abstract: An antibacterial ceramic contains an antibacterial material produced by loading an antibacterial metal such as silver on a calcium ceramic carrier and an inorganic material such as cordierite, and has a bulk density of 0.6-1.2 g/cm.sup.3. An antibacterial ceramic filter contains an antibacterial material produced by loading an antibacterial metal such as silver on a calcium ceramic carrier, an aggregate such as mullite, and a binder such as frit, and has a porosity of 20% or more. The light-weight antibacterial ceramic is suitably applicable to a roof garden or the like. The antibacterial ceramic filter can remove and extirpate various bacteria and suspensions.

Abstract: A porous filter for metal hot melt comprises ceramic aggregate particles bound by an inorganic binder. The aggregate particles contain not less than 50 wt % of particles with a shape factor in the range of 100 to 130 and the binder has needle-shaped crystals deposited on the surface thereof. By employing this filter, debris catching ability and initial impregnation of metal hot melt are highly improved.

Abstract: An apparatus for closing a succession of partly disengaged slide fastener coupling element chains with sliders mounted respectively thereon includes an element-engaging block assembly having a guide channel for constrictingly receiving a disengaged portion of each coupling element chain to close the same. The assembly includes a movable element-engaging block reciprocably movable toward and away from a stationary element-engaging block to selectively define therebetween the guide channel in timed relation to detection by a sensor of an element-free space between the successive chains and the slider.

Abstract: A method of forming a so-called space where fastener elements have been removed from a slide fastener chain in which fastener elements of synthetic resin have been woven into the edges of fastener tapes comprising disengaging right and left stringers from each other, setting each stringer on a working bed, keeping fixed all fastener elements in the space forming area of each stringer on the working bed by respective press pieces at their engaging heads, cutting at least the connecting threads extending through the legs of each fastener element at the front and rear end of the space forming area of each stringer, then pulling the fastener tapes away from the respective press pieces and thus pulling out the binding warp threads, core string and connecting threads from the fastener elements, so as to remove the fastener elements from each fastener tape and keep the binding warp threads, core string and connecting threads extended along the space forming area in the weft loops.
