Title: Washing method for water supply pipe
Inventor: KONO YUKIHIRO
IPC: E03B7/00
Filed: 1990-09-26
Abstract: PURPOSE:To completely perform both peeling and removal of rust and slime due to water hammering phenomena and agitating action and inhibition of generation of a foreign matter and sterilization due to action of ozone by discontinuously force-feeding ozone-contg. gas into the low part of the interval for washing a water supply pipe. CONSTITUTION:An interval for washing a water supply pipe P1 is set. Ozone- contg. gas is discontinuously force-fed at the pressure higher than water pressure in the low place in the interval for washing to this low place from an ozone force-feeding device A. Moreover the terminal of the interval for washing is opened to pass water and both ozone-contg. gas and water are discharged from this terminal. Both peeling and removal of rust and slime due to water hammering phenomena and agitating action and control of generation of a foreign matter and sterilization due to action of ozone are completely performed regardless of the structure of a water supply facility by this simple means.

IPC: G06K9/62
Filed: 1994-10-21
Abstract: PURPOSE:To provide an OCR controlling method through the use of an OCR classifying method based on a comparison inequality function(CIF) in order to acceleration-classify an OCR vector. CONSTITUTION:CIF is used as a general method for acceleration-classifying a non-classification input mark S into a template library which is previously classified. Correlation degree calculation is started between the inputted mark S and a template retrieved from the template library. The template with low correlation degree is removed before completing correlation degree calculation in order to accelerate correlation degree calculation. A template foregroud pixel can be correlated at first by sorting by template strength so that correlation degree calculation is further accelerated. The important non-coincident pixel is correlated at first by second sorting by identification power so that correlation degree calculation is further accelerated.

IPC: C21D9/573
Filed: 1992-09-25
Abstract: PURPOSE:To uniformly and rapidly cool a strip in the flat shape by letting the strip travel while being wound around plural cooling rolls having its front and back surfaces alternately in contact with the cooling rolls and making the contact pressure between the strip and the rolls on the low-temp. side higher than the pressure on the high temp. side. CONSTITUTION:The strip 4 travels while being wound round plural hollow-state rolls 3A-3E having its front and back surfaces alternately in contact with the rolls. Coolant 2 is circulated to the inner parts of these rolls 3A-3E and, if necessary, a cooling gas is blown from nozzles 5 having skirts 6. In the above cooling method for the strip, the contact pressure between the strip 4 and the rolls 3A-3E on the low temp. side is made to higher than the pressure on the high temp. side. For this purpose, e.g. in the cooling device 1A, the radius R1 of the rolls 3A-3C on the high temp. side is set to larger than the radius R2 of the rolls 3D, 3E on the low temp. side. As the other way, three or more pieces of the rolls are arranged, and the radiuses of these rollers are arranged as smaller in order from the high temp. side to the low temp. side. By this method, while holding the shape of the strip flat, the strip is uniformly, efficiently and rapidly cooled.

Title: Complementary signal generating circuit
Inventor: TOYOKURA MAKI
IPC: H03K5/151
Filed: 1991-10-04
Abstract: PURPOSE:To output a complementary signal in the same timing with respect to an input signal by inputting the input signal to input terminals of two differential amplifiers having the same configuration whose input terminals have mutally opposite phases. CONSTITUTION:An input signal 13 is inputted to the positive input of a 1st differential amplifier 11 and the negative input terminal of a 2nd differential amplifier 12 and an intermediate voltage between the input signal 13 is applied as a reference voltage 14. When the gain of the differential amplifier is considered to be infinite and the voltage at the positive input terminal is higher than the voltage at the negative input terminal, a high level is outputted and when lower, a low level is outputted. When the input signal 13 is changed from a voltage lower than the reference voltage 14 to a high voltage, the output of the 1st differential amplifier 11 is changed from a low level to a high level and the output of the 2nd differential amplifier is changed from the high level to the low level. When the input signal 13 is changed from the high to the low level with respect to the reference voltage 14, the outputs of the differential amplifiers 11, 12 are changed reversely to it. Thus, a complementary signal is outputted in the same timing with respect to one input signal.
