Abstract: PURPOSE:To efficiently purify miscellaneous waste water, by providing a water catchment tank equipped with an inflow opening for miscellaneous waste water and an outflow opening for draining water into a trench and having an opened part on the ground, and the trench having one end adjacent to the water catchment tank and constructed with a reinforcing body having U-reversed cross section. CONSTITUTION:Miscellaneous waste water after being separated from bulky solid matter by a water basket in a kitchen or directly as such from a bathroom or the like flows into a water catchment tank 1, through an inflow pipe 2 into a trench 4 and then along the lower bottom surface of the trench 4 toward a drainer tank 11 while partially permeating into soil. On this occasion, the water is purified with oxygen in air at first. The interior of the trench 4 is held at a nearly constant temp. and humidity throughout the year, and air-permeability is good enough to offer a splendid dwelling for aquatic and soil bacteria, microbes, protozoans, earthworms, etc. These organisms propagate using the miscellaneous waste water as a nutritive source, and decompose and consume it. Consequently, the water is purified.

Inventor: NIHEI ISAO
IPC: F01K3/18
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To provide conversion efficiency from heat energy to power, especially high conversion efficiency in a low temperature by applying heat energy to liquid in a high-temperature liquid storage container so as to make high-pressure steam, transferring this steam to a low-temperature liquid storage container, adding pressure, causing the liquid to flow out at a high speed and generating power. SOLUTION: Heat energy is applied to liquid in a tightly sealed and pressure- resistant high-temperature liquid storage container 1, the liquid is heated to exceed a boiling point and by suppressing boiling, high-pressure steam is generated. This high-pressure steam is transferred to a tightly sealed and pressure-resistant low- temperature liquid storage container 7 and liquid in the container 7 is pressurized by the high-pressure steam. Then, the liquid is caused to flow out at a high speed and by actuating a power generator 11 such as water turbine with this high-speed flow, power is generated. After all the liquid flows out from the high-temperature liquid storage container 1, transferring of the high-pressure steam is stopped, the high-pressure steam of the low-temperature liquid storage container 7 is discharged and by storing the liquid again, the same operation is repeated.  Thus, the efficiency of converting heat energy into power is increased and even in a low temperature, high conversion efficiency is provided.

Title: Magnetic disk driving device
Inventor: OKADA SHINICHI
IPC: G11B19/12
Filed: 1986-03-27
Abstract: PURPOSE:To reduce power consumption by supplying a power source to a function detection means in the prescribed time only when a magnetic disk presence or absence detection means detects a magnetic disk. CONSTITUTION:When the magnetic disk is put in, a photocoupler output A can be obtained in the input of the magnetic disk presence or absence detection circuit 4, which converts the output into the outputs of pulses B and C. When the output B operates the power source 5 for a write protect detection circuit 1, a current is conducted in the circuit 1 only when the output B is turned on: otherwise, a current is turned off. On the other hand a protect detection output E is inputted to the circuit 1, and an output signal D in a state where the power source in some section is turned on by the output B is outputted. A write protect output holding circuit 2 detects the input of the output D at the time of inputting the output B, maintains said state, outputs a held output F and keeps outputting until the disk is released. Thus the power source is turned on only when the write protect function is detected, whereby the consumption of useless power can be prevented.
