IPC: C10B29/02
Filed: 1994-11-09
Abstract: PURPOSE: To enable cracks, etc., on the surfaces of wall bricks of a coke oven chamber to be repaired accurately, efficiently, and under remote monitoring by emptying the chamber, blowing a carbonization gas having a good diffusibility into the chamber at a high temp., and causing carbon generated by thermal decomposition to uniformly deposit on the surfaces of the wall bricks.

Title: Water draining device for ceiling mount type hot water supplier
Inventor: YONEMOTO MAKOTO
IPC: F24H9/16
Filed: 1986-11-19
Abstract: PURPOSE:To prevent freezing of water by making it possible to drain water without manipulating a water draining plug in a hot water supplier installed on ceiling by providing a water supply port of the hot water supplier with an air-charge valve which opens when the water supply pressure is applied to the valve and closes when the water supply pressure is gone. CONSTITUTION:When a device is used for normal purposes, that is, when a main water supply valve 2 is open, an air-charge valve 12 is closed by the pressure of supply water which is applied to a supply water port 3, and the device is used as a normal hot water supplier. During water drainage, the main plug 2 for supply water is closed, and then a supply hot water plug 11 is opened. Then the pressure applied to the air- charge valve 12 becomes almost the same as the atmospheric pressure and opens the air-charge valve 12. At this time, the relation between the head (h) in the water channel in a device A and the head H between the supply water port 3 and supply hot water plug 11 is h<H, so that the water staying in the plug A is drawn by the water in the supply hot water piping 10 due to the syphon effect, and air is introduced from the air-charge valve 12 to drain water completely from the hot water supply plug 11.

Title: Line connection device for data transmission
Inventor: HISAOKA KUNITOSHI
IPC: H04B7/24
Filed: 1993-09-27
Abstract: PURPOSE:To improve the transmission efficiency of the entire system by decreasing a waiting time of a subordinate station whose line connection is disable till a succeeding transmission period. CONSTITUTION:A control station 1 sends a connection request signal to each of subordinate stations 21-2N and receives a connection acknowledge signal from each of the subordinate stations 21-2N When no connection acknowledge signal is received from a subordinate station 2, it is set to be a failure (flag 0) of line connection. When the connection acknowledge signal is received, it is set to be a success (flag 1) of line connection and the state of the flag (I/O) is stored. Then names of subordinate stations 2 and its number ne whose connection is failed are calculated in the line connection procedure. Thus, the total transmission time Ttl, for a control signal or data or the like and an end request signal or the like to a subordinate station 2 under line connection is calculated and when the number ne of the subordinate stations 2 whose line connection is failed is increased, the transmission time Tl is decreased accordingly. Thus, the wait time for a transmission period for succeeding line connection is reduced.

Title: Self-regenerating dehumidifier
Inventor: NAKATSUJI TADAO
IPC: B01D53/26
Filed: 1993-09-28
Abstract: PURPOSE:To increase an energy efficiency at the time of regeneration and to eliminate the need for installing a moisture absorbing sensor by using an adsorbent and the material exhibiting an ion conductivity after moisture adsorption as main structural elements. CONSTITUTION:This dehumidifier having a self-regenerating ability and the moisture adsorbing sensor function is produced by using the adsorbent and the material exhibiting an ion conductivity after moisture adsorptiont as its main structural elements. When a moisture in gas is removed by a hygroscopic agent and the water is absorbed to the adsorbent, the adsorbent becomes to exhibit conductivity by the ion conductive material incorporated in the hygroscopic agent. Then, a rate of moisture adsorptiont is obtained from this conductivity (electrical resistance), and when this value reaches a prescribed value, power is supplied to the hygroscopic agent to generate heat and the moisture is allowed to evaporate and removed from the hygroscopic agent in which the moisture is allowed to saturate. The conductivity of the hygroscopic agent becomes small by removing the moisture in the hygroscopic agent, and current is no longer to flow and the dehumidifier is stopped automatically.

Abstract: PURPOSE:To realize the high output and low noise by means of one device by a method wherein a semiconductor laser is integrated in such a way that it is connected to an output terminal of a high-frequency-superposing circuit used to superpose a high frequency on a driving current of the semiconductor laser. CONSTITUTION:A semiconductor laser 1 of the BTRS structure is formed inside a recessed part formed at a semi-insulating GaAs substrate 4; a high-frequency- superposing circuit is formed on the surface// of the substrate 4. The high- frequency-superposing circuit is composed of a five-stage ring oscillator 3. A BFL(Buffered FET Logic) circuit is used for each inverter 2 constituting the ring oscillator 3. Because, as the structure of the semiconductor laser, the structure of a high-output laser, which has been used so far, is adopted, it is possible to obtain a high output. In addition, because a high frequency is superposed on a driving current, the spectrum is made to be a multi-mode and coherency is lowered; as a result, it is possible to maintain the low noise for the returned light.
