Title: Fabrication of semiconductor device
Inventor: OKAYAMA YASUSHI
IPC: H01L27/12
Filed: 1995-02-27
Abstract: PURPOSE: To deposit polysilicon having low sheet resistance stably in a short time by introducing the polysilicon and impurities alternately when a trench is filled with polysilicon for the purpose of isolation. CONSTITUTION: After a trench 11 is made in a substrate 10 by etching, an insulation film 12 is deposited on the entire surface. A polysilicon layer 13 is then formed on the entire surface followed by formation of a glass layer 14 containing impurities on the entire surface. Subsequently, a polysilicon layer 15 is formed on the entire surface thus finishing the filling of the trench 11. Finally, the impurities are diffused from the glass layer 14 through heat treatment process thus lowering the total sheet resistance of polysilicon layer filling the trench.

IPC: H01L29/73
Filed: 1988-02-23
Abstract: PURPOSE:To perform the isolation of elements with certainty when a compound semiconductor is integrated, by performing the isolation of a base aside from other element isolation in the case of a heterojunction bipolar transistor. CONSTITUTION:An n<+>-type GaAs collector connection layer 1, an n-type GaAs collector 2, a p-type GaAs base 3, an n-type AlGaAs emitter 4, an n<+>-type GaAs emitter connection layer 5 are superimposed on a semi-insulating GaAs substrate 14. Mg and P ions are implanted to form a p-type external base 6 and a base electrode 7, an SiO2 protecting film 8, and an emitter electrode 9 are attached. Then, high resistance layers 10 for isolating the collector from the base are formed by B-ion implantation; and besides, a base layer 2 is etched with CCl4 and the like and then, it is isolated by grooves 11. Further, a layer isolation high resistance layer 13 is provided by H-ion implantation. As such a structure makes a p-type base layer B highly resistive independently, this device allows the n-type emitter and collector to be highly resistive on condition that is performed with the process of optimum ion implantation. Thus, element isolation is performed with certainty.

Title: Continuous roll forming method of steel pipe
Inventor: TAKAMADATE CHIHARU
IPC: B21D5/12
Filed: 1979-03-31
Abstract: PURPOSE: To form a thin-walled and broad-width steel strip without any buckling phenomena of its edge parts and make possible smooth pipe making by providing the edge guide shoes of the bearing surface of the same shape as that of the outside circumference of the curved steel strip between the forming rolls in the conveying direction of the steel strip.  
     CONSTITUTION: Edge guide shoes 40W46 are disposed between rolls, such as between vertical rolls 11 and breakdown rolls 21. For example, the shoes 42 are provided in such a manner as to be able to move a pair of blocks 42b, 42c out of a housing 42a symmetrically to the centerline in the lengthwise direction of the steel strip and in its width direction. These are provided with the bearing faces 42b' and 42c' of the same shape as the outside circumferential shape of the steel strip B formed by the pre-stage forming rolls 12 or of the radius of curvature approximately equall to that of the outside circumferential face of the steel strip in the shoe 42 position. Further, while the edge parts E, E are being restrained at the bearing faces, the steel strip is conveyed in the dropout arrow direction. This provides the effect substantially similar to that when the distance between the centers of the forming rolls is reduced, thus the buckling phenomena of the edge parts of the steel strip no longer occur.

Title: Packet transmission method
Inventor: KENGAKU AKIHIKO
IPC: H04L12/28
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To shorten a packet transmission interval by utilizing a third duration shorter than the mean value of a second duration in place of the second duration when continuously transmitting packets from a radio packet terminal. SOLUTION: When arranging three radio packet terminals SA, SB and SC to use the same radio channel in mutually overlapped radio zones, a transmission request is almost continuously generated at this radio packet terminal SA and until this transmission request is interrupted or the other radio packet terminals SB and SC first start transmission, the radio packet terminal SA determines transmission start timing while using a continuous transmission interval TC in place of a back-off interval TB. Since the continuous transmission interval TC is shorter than the mean value of the back-off interval TB, packets can be preferentially transmitted by using the continuous transmission interval TC. Therefore, in the case of continuous packet transmission, throughput can be improved.

Title: Printing head
Inventor: CHIKAOKA YASUJI
IPC: B41J2/295
Filed: 1990-02-20
Abstract: PURPOSE:To reduce the rolling of a printing arm to meet a higher printing speed and to improve a durability by a method wherein the printing arm is so tapered that the board thickness at right angles to the surface is gradually reduced from the base part toward the top end. CONSTITUTION:When a voltage is applied between both the electrodes of a piezoelectric element 1, the piezoelectric element 1 expands in a direction of an arrow X by a predetermined length. Based on this expansion, a movable element 5 is displaced. A plate spring 7 on the side of the movable element 5 is largely deflected to a plate spring 6 on the side of a frame 2, whereby an angular moment occurs in an actuator 8 of a printing arm 10 in a direction of an arrow P to tilt the printing arm 10 forward. The board thickness of the printing arm 10 at right angles to the surface is gradually reduced from a base part 10b toward a top end 10c thereof. This form effectively reduces the moment of inertia of the printing arm 10 during a forward and backward movement, thus resulting in the smooth reciprocation of the arm. Furthermore, a board thickness on the side of the base part 10b has a predetermined value t1 to prevent the reduction of transverse rigidity at the appropriate part. A board thickness t2 on the side of the top part 10c is made small to effectively reduce a rolling.

Title: Method and apparatus for maintaining service life of vertical roll in vertical rolling mill
Inventor: TAKEI HIROMITSU
IPC: B21B13/06
Filed: 1978-04-04
Abstract: PURPOSE:The vertical roll life and working ratio are drastically prolonged by displacing the rolls in the roll axis direction at specified rolling number intervals so that vertical rolls are contacted with material to be rolled at different positions. CONSTITUTION:Vertical rolls 11 are used at their lower portions to roll the width of material 2 to be rolled until the roll surface is reached to a specified roughening. Then the rolls 1, 1 are moved downward in the roll axis direction by a distance slightly greater that the thickness of the material 2, and width rolling of the material is performed by rolls 1, 1 using new portions avoiding the use of roughened portions a. When these new portions are roughened, the rolls 1, 1 are further lowered. Thus, the rolling process is successively repeated. Such roll life prolong device is operated so that up-down housing 5 supporting the roll chuck 3, 3 of the roll 1, 1 are vertically moved by the driving device 9, thereby to displace the roll 1 in the roll axis direction.
