Title: Frequency discriminator
Inventor: ZAIZEN KATSUNORI
IPC: G01R23/15
Filed: 1985-04-12
Abstract: PURPOSE:To discriminate the frequency of a commercial power source precisely by storing two discrimination results of a discriminating means, comparing those two stored discrimination results with each other, and outputting a coincidence signal and stopping a timer when they are equal to each other. CONSTITUTION:A frequency discrimination device is provided with the discriminating means 1 which discriminates the frequency of the commercial power source, the timer 2 which outputs a discriminating operation start signal to the means 1, a sequential storage means 4 which stores the discrimination result of the means 1 successively, and a comparing means 4 which compares two discrimination results with each other and then outputs the coincidence signal and also stops the timer 2 when they are equal to each other. When the discrimination start signal is outputted by the timer 2, the discrimination results of the discriminating means 1 are stored in memories 3a and 3b of the storage means 3 successively. The comparing means 4 compares the last and current discrimination results stored in the memories 3a and 3b with each other to repeat the operation while replacing the current discrimination value with a temporary decision value when they are not coincident or to output the coincidence signal and stops the timer 2 when they are coincident, thereby finishing the discriminating operation.

Title: Telephone number display system
Inventor: ARAYAMA KAZUHIKO
IPC: H04M1/2745
Filed: 1990-03-27
Abstract: PURPOSE:To easily recognize a telephone number by dividing a telephone number entered as a continuous number into a toll station number, a local station number and a subscriber and displaying the telephone number in a form of the telephone number used usually. CONSTITUTION:A control section 1 reads sequentially a toll station number stored in a storage means 3 when a head number of an entered telephone number is '0', reads a number of same plural number of digits and collates them and extracts the number of digit number as a toll station number when there is any coincident number. Then the remaining number is sorted as a local station number and inserts a delimiter such as a hyphen '-' between the local station number and a subscriber number and between the toll station number and the local station number and displays the result onto a display means 4. When a head number is not '0', the remaining number extracted from the subscriber number from the telephone number stored in the internal memory is sorted as the local station number and a delimiter such as a hyphen '-' is inserted between the local station number and the subscriber number and the result is displayed onto the display means 4.

Title: Air conditioner
Inventor: KODAMA YOSHIHIRO
IPC: F24F13/22
Filed: 1988-04-01
Abstract: PURPOSE:To prevent water drips separated from a heat exchanger and drain water accumulated in water receptacle from blowing by a method wherein a shielding plate is arranged below the heat exchanger in such a way as it may be crossed at a right angle with a supplied air and an air speed flowing between the heat exchanger and the water receptacle is reduced. CONSTITUTION:Air sucked from an air suction port 4 passes through a heat exchanger 1 and guided to an inlet port of a blower. A part of the air passes through a clearance between the heat exchanger 1 and the water receptacle 2. At this time, a shielding plate 7 is arranged in such a way it may be crossed at a right angle with air flowing between the heat exchanger 1 and the water receptacle 2, resulting in that eddy flow can be generated at a back surface of the shielding plate 7. Since a negative pressure part is formed at the back surface, resulting in that the flow speed of air is decreased. When the air drops from the heat exchanger 1 to the water receptacle 2, the air may not blow away the water drops. It is also possible to prevent drain water accumulated in the water receptacle 2 from being blown away.

A DC voltage reference Vdc* and a frequency reference F* are provided on the basis of said speed reference to control said power inverter 4 via frequency controller 11 so that a motor 5 decelerates. A reduction ratio variable signal R* is obtained by an adjustable ratio variable signal compouting element 12 from a difference  V between the voltage Vdc of said capacitor 3 obtained by a voltage detector 9 and the voltage reference Vdc* and inputted to the adjustable speed computing element 8. Thus, a regenerative energy is controlled and a motor is decelerated in the shortest time.

Title: Ultrasonic snowfall gauge
Inventor: SATOU TSUTOMU
IPC: G01S15/10
Filed: 1979-06-21
Abstract: PURPOSE:To prevent the outputting of an error snowfall value due to stagnant water, etc., by making a reflective surface to be measured of a substance higher in ultrasonic reflection coefficient than snow and by regarding the reflection level of the surface as reference one. CONSTITUTION:Receiving head 21 receives a tone burst wave, emitted by transmitting head 14 and reflected by a snow surface, and then receiving amplifier 22 amplifies this up to a fixed level to set the reflection level of reflective surface 15 high in reflection coefficient. Reference unit 25 applies comparators 23 and 24 with reference voltages of 100%Xalpha and 100%Xbeta and comparators 23 and 24, only when deciding that the output of receiving amplifier 22 are greater than 100%Xalpha and 100%Xbeta, inputs the detection output to control part 1. In snowfall measurement, the depth of a snowfall is generally found from the time from the emission of the tone burst wave to the appearance of the 1st pulse at the output of comparator 24, but in this case, control part 1 invalidates the output of comparator 24 while output pulses arrive from comparator 23. Consequently, the outputting of an error snowfall value due to stagnant water can be prevented.

Title: Decomposition method for dioxin in incinerated ash

IPC: A62D3/176
Filed: 1991-04-12
Abstract: PURPOSE:To make the dioxin in incinerated ash completely harmless by extracting the dioxin in incinerated ash with methanol, and radiating ultraviolet rays with a specific wavelength to the solution. CONSTITUTION:Fly ash (containing dioxane 200ng/g)10kg is repeatedly extracted at 50 deg.C with methanol 100kg. Only methanol is distilled from this methanol solution and condensed into the dioxin concentration 100ng/g. The dioxin methanol solution is nearly transparent and colorless, various organic substances are not extracted, thus most of the dioxin is decomposed by the radiation of laser rays Xe-Cl (308nm). No methanol is decomposed by the radiation of laser rays unlike the case when phenol is used as a solvent, and methanol can be again recycled and utilizes as the solvent. When ultraviolet rays are directly radiated to fly ash, the shade portion of light is eliminated, thus the efficiently is largely improved.
