Title: Concrete corrosion inhibitor
Inventor: OKAMURA KAZUTOMI
IPC: C04B111/20
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To obtain the corrosion inhibitor which is inexpensive and safe and capable of effectively preventing the corrosion of concrete without polluting environment by using a formic acid compd. as the effective component. SOLUTION: Formic acid, sodium formate, calcium formate, etc., are appropriately used as the formic acid compd. When such a corrosion inhibitor is applied to construct a concrete structure, the inhibitor can be incorporated into the whole structure, but the inhibitor is applied on at least the surface of the concrete to produce a definite effect since the concrete corroding bacteria are generally aerobic. For example, concrete is placed with a precast concrete board contg. the corrosion inhibitor as the formwork, hardened and used as the structure with the formwork as the surface, and the structure is inhibited from corrosion.

IPC: G06F12/00
Filed: 1991-06-25
Abstract: PURPOSE:To reduce the power consumption and to increase the battery driving time by cutting properly the supply of power to the memory blocks which are not required to hold the data. CONSTITUTION:An image memory 28 consists of four memory blocks 28A-28D and writes the image data equivalent to one screen into the memory blocks in the order of transmission. When all storage data are read out of the block 28A, a CPU 10 cuts the supply of power to the block 28A with a control signal 54A sent to a power circuit 52A from a PIO 50. Thereafter the data are read out of the blocks 28B-28D and the supply of power is successively cut off to those memory blocks where all storage data are read out. Thus it is possible to reduce the power required for store of the data and to increase the battery driving time.

Abstract: PROBLEM TO BE SOLVED: To inexpensively and surely detect the operational abnormality of driving equipment such as blower or pump by detecting the operational abnormality and issuing an alarm when operation is not started at a scheduled driving time or when operating is detected during a scheduled stop period. SOLUTION: Only when a pump is never driven during a scheduled operating period, an AND gate 8 outputs a detecting signal Da of operational abnormality of 'H' synchronously with the end of the period and detects the operational abnormality of the pump. When it becomes the scheduled stop period, on the other hand, an AND gate 6 is turned on by a stop side gate pulse Gb and when the drive of the pump during the scheduled stop period is detected from a start/ stop signal Pi, this AND gate 6 outputs a detecting signal Db of operational abnormality of 'H' synchronously with this detection. Then, the detecting signals Da and Db of operational abnormality are supplied through an OR gate 10 to a monostable multivibrator 11 for warning command output and at that vibrator, a warning output is generated for a warning output period suitably set each time the detecting signals Da and Db are inputted.
