Title: Equipment and method both for ventilation of rearing facilities
Inventor: YOSHIDA HITOSHI
IPC: A01K1/00
Filed: 2000-03-21
Abstract: PROBLEM TO BE SOLVED: To provide a ventilation equipment for rearing facilities which enables the remarkable reduction of maintenance work for a net installed in an air outlet. SOLUTION: A wall 20 on which air flow blown out with a fan 18 impinges and the direction of the air flow is changed is installed in an exhaust passageway 12A located on the downstream side of the fan 18. A water sprinkler 30 for watering along the wall 20 is placed in the upper part of the wall 20. Air in rearing facilities which has been blown out with the fan 18 impinges against the wall 20 and the direction of the air flow is changed from a horizontal direction to an upward one. At this moment, the air flow impinges against the wall 20 after having passed along the watered region by using the sprinkler 30 before the wall 20, or flows along the wall 20 and impinges against water flowing over almost the whole area of the wall 20.  Thus, fragments of feathers and/or hairs, dust/or the like, in air are/is removed by being attached to drops of water or water itself, and the adhesion of the fragments of feathers and/or hairs, the dust, or the like, to a net 16 installed in an air outlet 14 is remarkably reduced.

Title: Method for inspecting printed wiring board
Inventor: NAGASAKI MASATO
IPC: H05K3/00
Filed: 2000-03-23
Abstract: PROBLEM TO BE SOLVED: To provide an inspection method with such high precision that a minute contaminant, etc. an can be detected and so that an inspection time is set to be short in the inspection of substrate wiring patterns and through holes. SOLUTION: The radially outward distance from a base point 20 to a point deviating from a through hole is measured and its is decided whether or not the radius or diameter of the through hole is in an allowable range for each inspection direction. For example, when the inspection is made by the radius of the through hole, when a contaminant, etc., is absent in a scanning line like in the directions of arrow 3 and the shape of the peripheral part of a through hole 13 is normal, it is decided normal because the transformed distance is equal to the formal radius of the through hole registered previously. When a contaminant 15 is present is the scanning line like in the direction of a arrow 5 since the measured radius of the through hole is shorter than the formal radius of the through hole, it is decided that an inspected substrate is a failure. Accordingly, since the minute contaminant, etc., can be detected, the precision is high and an inspection time is shortened.

Title: Semiconductor integrated circuit
Inventor: KUROTSU SATORU
IPC: G11C11/407
Filed: 2000-03-27
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit having two operating modes, that is, a standby mode and a drive mode that can reduce a time until a level of a pseudo power line is stabilized when the semiconductor integrated circuit shifts from the standby mode to the drive mode. SOLUTION: The semiconductor integrated circuit 11 is provided with a logic circuit 13 and a control circuit 15. The logic circuit 13 is driven by a voltage between a level of the pseudo power line 17 and a level of a ground line 16. In the case of a conventional semiconductor integrated circuit, since an interruption circuit shuts off a level supplied to the pseudo power line, the level of the pseudo power line is set to a ground level. On the other hand, in the semiconductor integrated circuit the control circuit applies an intermediate level between the power supply level and the ground level to the pseudo power line. Thus, when the semiconductor integrated circuit shifts from the standby mode to the drive mode, a level change in the pseudo power line can be decreased.
