Title: Waveform equalization filter device
Inventor: SOMEYA IKUO
IPC: H03H17/00
Filed: 1990-07-09
Abstract: PURPOSE:To attain waveform equalization of a different distortion signal with one waveform equalization filter by setting a tap coefficient of a coefficient multiplier in the waveform equalization filter corresponding to clock changeover. CONSTITUTION:When a clock changeover circuit 2 is selected from the CATV mode into the satellite broadcast BS mode, the clock changeover circuit 2 is thrown to the position shown in broken lines. That is, a clock CLK outputted from the clock changeover circuit 2 is a 2nd clock CLK 2 and fed to unit delay elements 101-106. A control means 3 monitors the switching state of a clock switching circuit 2, and detects the changeover of the clock changeover circuit 2 to set coefficients k1-k2+1 to coefficient multipliers 111-117 corresponding to the 2nd clock CLK 2. Thus, an optimum signal waveform equalization corresponding to the distortion characteristic is implemented with simple circuit constitution.

IPC: C11D7/20
Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To produce a cleaning implement capable of easily removing stains completely without impairing the object to be cleaned and without causing chapped hands, and useful for removing stains is a pipe by blending a water-soluble resin with an inorganic raw material (e.g. talc) as a principal constituent and then by molding the composition so as to have a preferred shape. SOLUTION: This cleaning implement is produced by blending (A) a raw material (which is talc, magnesium carbonate, calcium carbonate, silica, or the like) as a principal constituent with (B) a water-soluble resin [e.g. sodium carboxymethylcellulose, dextrin or poly(vinyl alcohol)] and then by molding the composition so as to have a preferred shape. The tool material 1 has a sectional form of partially making a cut in an isosceles triangle having a obtuse angle 2 and two other acute angles 3. The notch 4 located in the center of the bottom part has a similar figure to the isosceles triangle. Arc-like notches are formed around the obtuse angle 2 part and the obtuse angle 2 part is formed in a rounded shape, which enable use to remove smears in arc parts and narrow parts in earthenware in a lavatory or the like.

Title: Insect-proof structure for infrared beam sensor
Inventor: HAGIWARA HIROSHI
IPC: A01M29/16
Filed: 1994-08-01
Abstract: PURPOSE:To prevent an insect from intruding through a wiring hole or a vent into the sensor body or an optical system by providing a sound generator in the sensor body. CONSTITUTION:A fixing board 14 is provided with wiring holes for leading the wiring from a circuit board 15 to the outside and vents for ensuring ventilation in the sensor body 12. A sound generator 23 is mounted on the board 14. The sound generator 23 generates a low frequency, high frequency or ultrasonic sound, indistinguishable to human ear, through oscillation of an oscillatory member. When the generator 23 is driven constantly or every predetermined time, an insect, e.g. an ant, exhibits rejection to the low frequency, high frequency or ultrasonic sound. Consequently, the insect, e.g. an ant, is prevented from intruding through the wiring hole or the vent into the sensor body 12 or an optical system 18 thus eliminating a cause of erroneous function or failure.

Filed: 1988-07-20
Abstract: PURPOSE:To simplify the circuit by comparing an output of an integration circuit receiving a clock pulse with a prescribed duty ratio repeating the charge/ discharge at a prescribed time constant with a threshold level at the end of the pulse and outputting the pulse as it is or with inversion. CONSTITUTION:With an external master clock C1 having a narrow width inputted, even when an input potential of a comparator 6 with hysteresis charges a capacitor 4 when a MOSFET 3 is turned on while the level of the clock C1 is logical charge, the capacitor 4 is discharged by a MOSFET 2 turned on by an output of an inverter 1 and the output of the comparator 6 remains logical '0' and a wide pulse being the inversion of the clock C1 is outputted to a terminal 11. When an external master clock C2 with a wide width is inputted, the output of the comparator 5 is logical '1' or logical '0' but a D-FF 6 holds an output of the comparator 5 at the trailing of the clock C2, the level of a terminal Q of the FF6 is always logical '1' and the output 11 has a wide pulse. Thus, a pulse with a prescribed width is generated by a simple circuit.
