Abstract: PURPOSE:To prevent lifting of a large volume of the underground water with the device for sucking and removing the volatile materials in the ground via a tubular body inserted into the ground by extending and installing the tubular body down to a position where the level of the underground water sucked together with the volatile materials balances. CONSTITUTION:The underground water is sucked from a strainer part 1 via the tubular body provided with a separating part (part for separating gas from liquid) 3 in mid-way by operation of a vacuum pump 5 and the volatile materials separated in this separating part 3 are introduced to a purification treating device 7 where the materials are subjected to treatments, such as decomposition by heating, decomposition by microorganisms (bacteria) and adsorption onto active carbon. Many holes are bored in the lower end part of the strainer part 1 on the side to be inserted into the ground. The part provided with these holes is inserted down to the surface side lower than the underground water level LO. The separating part 3 is connected to the strainer part 1 and is installed under or above the ground according to the depth of the underground water level LO and in a position upper than the position where the level of the underground water balances.

Abstract: PURPOSE:To execute the precise continuation time control by giving prescribed similarity, when the continuation time of a partial pattern of an input voice is within a specific allowable range, and giving similarity corresponding to a shift from the average, when the continuation time is outside the specified allowable range. CONSTITUTION:The above system is provided with a feature sequence converting means for converting an inputted voice waveform to an input voice pattern being a time series of a feature vector, and similarity/non-similarity of a partial pattern X and a standard pattern Y of the input voice pattern is calculated by the sum of similarity/non-similarity Rv of the respective feature vectors x, y, and similarity/non-similarity Rt of the continuation time i-m of the partial pattern X and the continuation time l of the standard pattern Y. In this case, the similarity/non-similarity of the continuation time is calculated as Rt=min(a, b-c (i-m-l)<2>). In this regard, a to c denote parameters for evaluating the continuation time. Accordingly, when the continuation time i-m of the partial pattern of the input voice is within an allowable range of the expression, prescribed similarity (a) is given, and when the time is outside the allowable range, b-c (i-m-l)<2> is given.

Title: Hetero-junction bipolar transistor
Inventor: KURISHIMA KENJI
IPC: H01L29/205
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To provide an emitter mesa structure of a hetero-junction bipolar transistor(HBT) having an InP emitter mesa which suppresses the surface leak current due to an electric stress. SOLUTION: The mesa type hetero-junction bipolar transistor comprises a collector layer, p-type base layer and n-type InP emitter layer 2 laminated on a semiconductor substrate. The InP emitter mesa side wall is composed of crystal planes not crystallographically equivalent to the (011) plane. If it is composed of only a plane equivalent to the (011) plane, the emitter surface leak current due to an electric stress can be prevented, esp. the energization initial deterioration can be suppressed which often causes the problem when the HBT is energized.

Title: Hot rolling method for metallic material
Inventor: HACHITANI NARIO
IPC: B21B37/76
Filed: 1979-04-13
Abstract: PURPOSE:To contrive the energy saving and the prevention of scale loss, by partly or wholly covering the high temperature material to be rolled with bubbles for preventing the temperature drop and the oxidization on the way of the hot rolling pass. CONSTITUTION:The bubbles 4 produced from the nozzles 3a, 3b, 3c, of the bubble sprayer 3 are blown against the upper surface 2a and the side plane 2b of the high temperature slab 2 carried on the roll gangs 1a, 1b, 1c, in order to cover the slab 2 with the air bubbles; hereupon, the controller 6 gives the work command to the bubble generator-feeder 7 according to the signal input sent from the photoelectric detector 5 detecting the arrival of the slab 2; hereby, the generator-feeder 7 actuates the bubble sprayer 3. Since the slab 2 is partly or wholly surrounded by bubbles at an aribitrary position in the hot rolling pass, the heat radiation and the oxidization are prevented. Besides, the bubbles do not disturb the rolling work, hence, the rolling work may be continued under existence of bubbles, or in some cases,  bubbles are removed away by the scraper, etc.

Title: Glass and ceramic container having protection cover
Inventor: KARURO MAATEIN GORINO
IPC: C03C17/32
Filed: 1990-02-23
Abstract: PURPOSE: To hold fragments when a container is broken and improve holding ability of liquid in the container by strongly bonding a polymer coating in a small selected region on a surface of a container. CONSTITUTION: A chemical primer which strongly reacts both with a container material and a coating is used to process only a small region of a container, so that when the container is in contact with a polymer coating, the coating strongly attaches only on the region processed by the primer while bonding between the coating and a container surface is relatively weak in an unprocessed region of the container. The small region strongly bonded allows polymers to tightly attach to the container surface thereby preventing peeling, and prevents liquid from being enclosed in an interface region between the polymer coating and the container surface.  The relatively weak bonding between the polymer coating and the container surface over an entire remaining part of the container allows the coating to flex in order to prevent, in case of breakage of the container, fragments resulting from the breakage from sticking against the coating. That is, the fragments come off from the coating before they cut it.

Title: Electron beam welding method
Inventor: KOBAYASHI TOSHIYUKI
IPC: B23K15/00
Filed: 1979-04-11
Abstract: PURPOSE: To prevent the occurrence of phenomena such as weld crack owing to the quenching of weld portions, and machining difficulty as with conventional welding, by radiating an electron beam again to the portion welded by an electron beam thereby delaying the rate of cooling of said welded portion.  
     CONSTITUTION: In welding the points AWE on the weld one of the welding works 4 on a truck 4 by the electron beam 2 of an electron gun 1, first the A-B points are welded at the power density of welding, after which the electron beam 2 is returned to the A point, is set at the power density of postheating and is moved up to the B point. Thence, again the B-C points are welded at the power density of the welding, after which it is returned to the B point. From this point on, the foregoing similar operations are repeated and the entire length AE is welded. By delaying the rate of cooling of the welded portion in this way, the weld crack owing to quenching is eliminated and the defect of conventional method that working becomes difficult on account of increased hardness of the weld zone is improved.
