Abstract: An image reducing apparatus includes a black-pixel counting section for counting a number of black pixels in an N.times.M-pixel area in an original image represented by white and black levels, where N and M denote predetermined integers equal to or greater than 2; a pattern comparing section for comparing a pixel pattern in the N.times.M-pixel area and an area surrounding the N.times.M-pixel area with predetermined reference patterns; and a level determining section for determining a level of a pixel in a reduction-resultant image in accordance with the black-pixel number counted by the black-pixel counting section and with a result of the pattern comparison by the pattern comparing section, the reduction-resultant image pixel corresponding to the N.times.M-pixel area in the original image.

Abstract: A piezoelectric oscillator in which radiation of higher harmonic components is reduced. A piezoelectric vibrator and a semiconductor device are provided in an oscillation circuit for making the piezoelectric vibrator oscillate, as is a filter for cutting components in a predetermined frequency band or higher harmonic components of an oscillation signal outputted from the semiconductor device. The piezoelectric vibrator, the semiconductor device and the filter are packed in one package. Radiation of the higher harmonic components is reduced by placing the filter close to the oscillator, by providing a shielding or by operating portions of the oscillator output circuit with a reduced supply voltage.

Abstract: A novel process for preparing a gas absorbent, comprising the steps of adding sodium bromate to a mixture of sulfuric acid aqueous solution and active carbon, reacting them, separating solids from the reaction mixture, and drying said solids. The gas absorbent can be utilized as a reagent for preserving the freshness (inhibiting agent) of fruits, an inhibitor of flower withering, an inhibitor of bulb germinating and root sprouting, an inhibitor of plant withering, leaf falling or fruit falling, a reagent for controlling the growth and specialization of plants, a deodorant or an absorbent of organic compounds having double bonding or triple bonding.

Abstract: An electronic timepiece wherein a quartz crystal oscillator produces a timekeeping standard signal which is divided by a transformer means formed of silicon gate complementary MOS transistor elements. The output of the transfer means is applied to a drive circuit which in turn is coupled to a digital display formed of liquid crystal elements. Time correction is performed by two switches, one switch selecting the digit of the display to be corrected, the other correcting the number displayed at the selected digit.

Abstract: A compact electronic calculator having an input circuit defined by a plurality of lead switches mounted beneath an operative surface for selective actuation by a manually manipulatable permanent magnet. The calculator further includes a calculating circuit coupled to said input circuit and formed from LSI elements, display means formed from liquid crystal display elements and a battery power source.
