Title: Speaker system for reproduction of sound field
Inventor: SUZUKI TATSUYA
IPC: H04R1/30
Filed: 1994-01-18
Abstract: PURPOSE:To obtain an ideal letter-8 shaped dipole characteristic which is deep in notch from a low frequency sound area to a middle frequency by composing the speaker system of a rear open cabinet whose speaker unit has the front and the rear which are the same in shape and open and providing the acoustic equalizer with a shape that makes its sound pressure characteristic on the front side coincide with one on the rear side. CONSTITUTION:A speaker unit 2 and an acoustic equalizer 1 which has the same shape as the frame 2a and is mounted on the front surface of the speaker unit 2 are mounted on a rear surface open cabinet 3 where a horn type sound path is provided. By providing this acoustic equalizer 1, the sound pressure characteristics of the front side and the rear side almost match in the middle register of 800Hz to 4kHz. Therefore, only if the one equalizer is used in the speaker unit 2, cost can be reduced, the unmatching of the front and rear sound pressure in the middle frequency sound area can be corrected, and further, an ideal letter-8 shaped dipole characteristic which is deep in notch in the low frequency sound area to the middle sound area can be obtained.

Title: Mixture preventing device for heat medium substitution tank
Inventor: YASUZAWA KAZUHITO
IPC: F24F5/00
Filed: 1980-01-15
Abstract: PURPOSE: To prevent staying of a low-temperature heat medium and mixture of it with a high-temperature  heat medium and to improve a heat collection efficiency, by a method wherein a plural number of passage  holes for heat medium, tilting in the same direction, are mounted between an upper and a lower surface of a  plural number of partitions positioned in a substitition tank.   
     CONSTITUTION: A heat medium feed pipe 2 is connected to an upper part of a substitution tank 1 and a heat  medium discharge pipe 3 to a lower part thereof. Between an upper and a lower surface of a plural number  of partitions 4, which partition the inside of the substitution tank 1 horizontally, 4 passage holes 5 for heat  medium, which incline downward in a circumferential direction and the inclination of a point on the partition  decreases the further outwards on the partition this point is situated, are formed at intervals of 90°. A high- temperature heat medium, and a low-temperature heat medium, which is expelled by the high-temperature  heat medium produce a rotary current when they pass the passage holes 5 for heat medium. Said rotary  current substitutes the high-temperature heat medium for the low-temperature heat medium after discharging  the low-temperature heat medium through a heat medium discharge pipe 3 by means of the high-temperature  heat medium fed by a heat medium feed pipe 2, without mixture of the low-temperature heat medium with  the high-temperature heat medium due to stay in the substitution tank 1 and the production of a turbulent  flow. A heat collection efficiency can thus be improved.

Filed: 1999-01-08
Abstract: PROBLEM TO BE SOLVED: To quickly and accurately read a response sentence in electronic mail. SOLUTION: A means 21 stores mail sentences in a temporarily data storing section 31 by taking out the sentences from a mail box 51 one sentence by one sentence. A means 22 takes out a mail sentence one line by one line from the section 31, discriminates whether or not the sentence is a quotation by comparing the sentence with the data stored in a quotation mark storing section 32, and, when the sentence is a quotation, stores the quotation in a quotation storing section 33. A means 23 reads a sentence which is discriminated as a response sentence, retrieves the content to confirm whether or not a word indicating a quotation before or after the response sentence is included by referring to a response sentence dictionary storing section 34, and correlates the quotation to the response sentence. A means 24 can discriminate the response sentence immediately before a quotation.  A means 43 displays the quotation stored in the quotation storing section 33 in the upper section of a window and a means 45 displays the response sentence stored in the response sentence storing section 35 in the lower section of the window. A means 42 can separately scroll the upper and lower sections of the window and a means 44 is used for manually correcting the deviation between the quotation and response sentence.
