Filed: 1993-08-27
Abstract: PURPOSE:To open a voice massage by an arbitrary timing by storing a voice and data in a storage part, and controlling a data transfer means for transmitting simultaneously the voice and the data. CONSTITUTION:A voice and data to be transmitted are stored in advance in a storage part 2, and a data transfer means (a voice/data MODEM) 3 which can transmit simultaneously the voice and the data is used. When transmission is instructed from an input part 7, a data control means 11 controls the voice/ data MODEM 3 so that the stored voice is transmitted simultaneously, in addition to the data which is being transmitted, in accordance with the given instruction, while the data stored in the storage part 2 is being transmitted. That is, in the case the time required for transmitting the voice is shorter than the time required for transmitting the data, the data control means 11 starts to transmit the voice, at the time point when a voice transmission start notice is sent from a receiving side, or the remaining time for transmitting the data becomes equal to the time required for transmitting the voice, after transmission of the data is started.

Title: High-raised warehouse for cylindrical article
Inventor: IGATA SUETA
IPC: B66C1/24
Filed: 1991-07-31
Abstract: PURPOSE:To store cylindrical article in a rack with high efficiency by installing an arm at such a position as it makes no interference with a rack bar when taking-in/out is carried out with a hole of the cylindrical article supported by the arm. CONSTITUTION:For carrying out a cylindrical article 1 hung from a rack bar 2, a stacker crane 3 is moved to a hole position of the article by traveling and lifting to traverse a traversing car 8 in the direction of the article to be carried out and inset the arm 9 in the hole. The arm 9 has a prescribed clearance ensured in a width direction from both sides of the rack bar 2 inside the hole of the cylindrical article 1, and is inserted without interference with the rack bar 2. Then, by raising a carriage 6, the article 1 is lifted up to return the traveling car 8 inside the carriage 6 and make the stacker crane 3 go to a delivery entrance. For carrying-in, the article 1 is lifted up to the rack bar 2 by contrary operation to the above. It is thus possible to decrease the rack height and store articles with high efficiency.

Title: Activated carbon
Inventor: ONO AKINOBU
IPC: C01B31/08
Filed: 1993-08-05
Abstract: PURPOSE:To remove only unwanted components in water using an activated carbon on which are adsorbed ions having a strong affinity for active carbon. CONSTITUTION:Ions having a strong affinity for active carbon, such as nitrate ions or sulfate ions, are applied to activated carbon which holds ions having a weak affinity for active carbon, such as chlorine ions. Consequently, the latler ions are replaced with the former ions. After that, ions having the same or weaker affinity will not be adsorbed on the activated carbon, if such ions come into contact with the activated carbon. Consequently, an anion such as chlorine ion is no longer adsorbed into the activated carbon, and the pH value of a treated water no longer increases. Therefore, if this activated carbon is used, the water can be treated by the activated carbon in such a state that the required ions in the water before treatment with the activated carbon are contained as they are. It is recommended that about 1.6mg of the ions with a strong affinity be applied to one gram of activated carbon.

IPC: H04N21/262
Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To efficiently handle each of a sporadic transmission request and an intensive transmission request to the same title. SOLUTION: In processing the transmission request from a client, a schedule control part 124 refers to a transmission-scheduled title management area 208.

Then, the queue waiting for the transmission schedule is restored in the transmission-scheduled title management area 208. When the queue exists, the corresponding request is registered in the pertinent queue.  When it becomes transmission schedule time, pertinent video data are transmitted to all transmission request source client devices in the pertinent queue, the pertinent queue is made idle and transmission schedule is updated.

Filed: 1983-11-14
Abstract: PURPOSE:To aim at enhancing the control ability of an automatic speed change unit and as well at making compact thereof, by utilizing a small accumulator to delay the rise of hydraulic pressure for a long time. CONSTITUTION:A spool valve 460 constituting a mechanism for the rise of hydraulic pressure and disposed between a hydraulic pressure source and a hydraulic servo, is subjected from above to the feed-back of the output pressure Po of an output oil passage 1Q, and is communicated from below with the output oil passage 1Q through a constriction 480. In addition, there is provided a spool 471 for adjusting the communication between an inport 481 which receives an accumulator pressure Pa from an accumulator 490 through an oil passage 1R and communicates with the hydraulic pressure source through an oil passage 1Q, and an output port 483 which communicates with the output passage 1Q. Further, since the hydraulic servo is directly communicated without through the constriction 480, and therefore the size of the constriction 480 is made small to a desired value, thereby the adjustment of rise of hydraulic pressure may be made over a long time even though the capacity of the accumulator 490 is small.
