Abstract: There is provided a drive circuit of a solid-state image pickup device capable of generating pulse for vertical scanning the interval of which changes non-linearly and pulse other than the pulse for vertical scanning without increasing a circuit size and communication time for setting an electronic shutter. There is provided a drive circuit of a solid-state image pickup device including a polynomial arithmetic operation unit for carrying out an arithmetic operation of first or higher order of polynomial; an arithmetic operation controller of generating a variable of the polynomial to control an arithmetic operation in the polynomial arithmetic operation unit; and a pulse generator of generating a pulse based on a result of an arithmetic operation on a polynomial of the polynomial arithmetic operation unit.

Abstract: Wet refuse together with some amount of water may be deposited through a drain port of a sink tub in a common household. The wet refuse is then comminuted into finely divided pieces in a fully automatic manner by a wet refuse crusher without the need for any manual operation, and charged, together with water, into a wet refuse disposer containing a bed or matrix of particulate material loaded with microorganism such as soil bacteria capable of decomposing organics where all of the wet refuse is decomposed and consumed in at most about half a day as the finely divided pieces of wet refuse have tens or hundreds of times as great surface area as the wet refuse in its original form. The water entrained with the wet refuse is passed and discharged through the particulate bed material having a filtering function.

Abstract: A system for mechanically and biologically decomposing a garbage discharged from a house, a restaurant or the like at high operational efficiency is disclosed. The system includes a disposer for disintegrating the garbage into a large number of pieces, a solid/liquid separator for separating water from the disintegrated garbage and a garbage decomposing vessel for biologically dissolving the solid disintegrated garbage from which water has been substantially separated in the solid/liquid separator. To promote biological decomposition of the solid disintegrated garbage in the garbage decomposing vessel, pulverized wood is normally used instead of soil as a raw material for forming a decomposing bacillus growing bed in the garbage decomposing vessel. Prior to practical use, the pulverized wood is thermally processed.
