Title: Method for controlling thickness of tube end of stretch reducer
Inventor: KAWABATA HIDEO
IPC: B21B37/78
Filed: 1993-03-23
Abstract: PURPOSE:To remarkably improve a product yield by reducing cutoff loss through real-time removal of generation of a thick wall part at a tube end in rolling by a stretch reducer. CONSTITUTION:Roll state detectors A1-An are equipped additionally at each of plural roll stands S1-Sn of the stretch reducer 1 to detect biting-in and passing-through of a tube stock 2 with respect to each of rolling rolls 3. The rotating speeds of the rolling rolls 3 are controlled to prevent the generation of thick wall parts at the tube ends in each of roll stands S1-Sn according to the detection of the front end or rear end of the tube stock 2 by a tube end detector 5. On one hand, when the roll state detector Ai of an arbitrary roll stand Si detects a biting-in or passing-through, a time difference between a control timing of the rotating speed control set in this roll stand Si and a detection timing is obtd. and the control timing of the rotating speed control at roll stands Si+1-Sn on a downsteam side is corrected based on this time difference.

Abstract: PROBLEM TO BE SOLVED: To make a metal nut so as to be storable in a member on one side, and also screwable in a member on the other in a simple structure even forming no internal thread in a soft member of a synthetic resin or the like, or integrally forming no metallic internal thread member in advance. SOLUTION: In the case where an internal thread is required to be formed in such a material as synthetic resin or the like where a thread ridge is apt to be worn out and broken by relatively repetitious screwedness at a spot where a screw is made so as not to be pierced through to the opposite side, or there is need to use a long screw to be pierced, a nut 274 is formed into an embedded type, whereby any formation of the internal thread into a base 208 made of a synthetic resin falls into disuse, so in the case where screwing operations are repeated over and over again as in the case of height adjustments, such a problem of nonconformity as damaging the thread ridge of the internal thread is solved.

Title: Paper feed device of copying machine and paper feed cassette used for copying machine
Inventor: MIYOSHI AKITAKE

Filed: 1983-04-12
Abstract: PURPOSE:To enable a paper feed cassette to be used irrespective of the volume size thereof by forming a cassette holding part with a cassette guide holding member for holding both right and left side guide parts without providing a cassette holding part over the entire width of the paper feed cassette. CONSTITUTION:Paper feed cassette 13 of a small volume is housed and held by allowing the guide members 20 to run on a plate spring 26 while deforming it and a stopper 22 to make close contact with the tip of the holding member 24 by inserting the right and left guide members 20 between the cassette guide holding member 24 and a guide member 25, sliding said guide members, and pressing down the rear end of a cassette 13. Further, paper feed cassette 12 of a large volume can be also housed and held in a similar manner. In this case, there is a step part entering the inside of the both right and left side parts on said members, so that there is no case where the cassette 12 itself makes close contact with the holding member 24 and prevents the insertion of any cassette. In this way, larger cassette housing space enables both cassettes of a small volume and a large volume to be freely housed.

Title: Method for preventing surface clacking of continuously cast steel ingot
Inventor: NAGAO NORIAKI
IPC: B21B1/00
Filed: 1986-03-24
Abstract: PURPOSE:To prevent surface cracking and to improve the yield of a product by cooling a continuously cast steel ingot in a cooling process at a specific cooling rate and starting hot rolling in a prescribed temp. range. CONSTITUTION:The steel ingot in the cooling process is cooled at a cooling rate of 1.0-10.0 deg.C/sec until the temp. for starting the hot rolling is attained and the hot rolling is started as it is at 1,050-950 deg.C at the time of subjecting the above-mentioned steel ingot to direct rolling. Since the cooling rate is controlled to the specific range, the remaining of the unsolidified part in the hot ingot fed to the rolling stage can be prevented. The surface cracking arising from the embrittlement of the liquid metal is, therefore, prevented and since the temp. for starting the hot rolling is controlled to the prescribed range, the deposition of sulfide from the liquid metal is prevented. The surface cracking of the steel ingot is prevented and the yield of the product is improved by such remedies in both ways.

Title: Gate-insulated bipolar transistor
Inventor: MIURA SHUNJI
IPC: H01L29/739
Filed: 1988-03-18
Abstract: PURPOSE:To prevent a latching effect without a diffusion potential between a source layer and a channel layer being exceeded by the potential change under a source layer, by collecting carrier to be injected from a drain region by one conductivity type layer in the drain region under the channel layer. CONSTITUTION:The same conductivity type P<+> type collector layer 32 as that of a channel forming layer is formed with substantially the same width in the N<-> type layer 2 of a drain region under the P-type layer 3 of a channel layer, and connected by a P<+> type layer 31 to the layer 3 and a source electrode. Part of carrier (hole) 11 injected from a P<+> type layer 1 to a drain region 2 is collected to the layer 32 of a collector layer, and the number of holes arriving at the layer 3 of an N<+> type layer 4 is reduced. An important point to design an IGBT is of an interval W of the region 2 between the layers 32 for collecting the carrier. If the interval is excessively narrow, resistance is increased against the carrier (electrons) injected from a source layer 4 designated by a solid line 12, thereby causing a voltage drop between a source electrode 7 and a drain electrode 8 to increase.

Abstract: PURPOSE:To improve electric power efficiency by providing impedance matching circuits between a high-frequency power generator and the starting point of a coaxial cable and between the final end of the coaxial cable and a discharging electrode respectively. CONSTITUTION:Impedance matching circuits 10, 11 are provided between a high-frequency power generator consisting of a high-frequency signal generator 1, a MOSFET 2, a DC power source 3, etc., and the starting point of a coaxial cable 4, and between the final end of a coaxial cable 4 and a contact 6 for feeding power to an electric discharge machining wire 5, respectively. Thereby, a high-frequency power can be efficiently introduced into the coaxial cable 4, while the output impedance of the impedance matching circuit 11 can be considered a net resistance from the standpoint of a discharging load side reducing the electrostatic capacity of a discharging portion.

Abstract: PROBLEM TO BE SOLVED: To expedite the temperature elevation of catalysts and to improve the purification capability of exhaust gases by providing an exhaust gas route with catalyst heaters which are obtained by forming catalyst layers on porous heating elements and are capable of heating the catalyst layers by utilizing the heat generated when these heating elements are energized. SOLUTION: At the time of operation of a catalyst unit for purifying the odorous components generated when crude refuse is treated, electrically insulating materials 3 are first heated from outside by a heating means 5 to restore the electrical insulation characteristic of the electrically insulating material 3. A commercial AC powder source is then connected between power feed terminals 4 and 4' and the catalyst heaters 1 are operated. As a result, expanded metals 2 are made to generate heat to activate the catalyst layers formed on the surfaces. When the exhaust gases pass the catalyst heaters 1 in this state, the odorous components in the exhaust gases are oxidation decomposed by the catalyst layers on the surfaces of the expanded metals 2.  The catalyst layers preferably consist of under-coating layers consisting of a sintered oxide containing at least barium, cerium and aluminum and the noble metal catalysts disposed thereon.
