Title: Manufacture of vertical type bipolar transistor
Inventor: HIKITA TOMOYUKI
IPC: H01L29/73
Filed: 1987-07-22
Abstract: PURPOSE:To prepare a plurality of vertical type P-N-P transistors having different characteristics onto the same chip by selectively etching one part of an epitaxial growth layer and changing the width of a base region in the specified transistor. CONSTITUTION:When an N<+> buried layer 2, P<+> buried layers 3, 4 and an N-type epitaxial layer 5 are formed onto a P-type silicon substrate 1, the N-type epitaxial layer 5 in a section, to which an emitter region is shaped, is etched, and the width of a base region is controlled. The N-type epitaxial layer in the section, in which the emitter region is formed, is etched selectively, thus shaping two kinds or more of base region width onto the same substrate. Accordingly, a plurality of vertical type bipolar transistors having different characteristics can be manufactured onto the same chip without largely increasing the number of processes, thus promoting the improvement in transistor characteristics.

Title: Heat pipe
Inventor: IWAI ICHIROU
IPC: F28D15/02
Filed: 1982-10-20
Abstract: PURPOSE:To prevent performance from being lowered due to collection of hydrogen gas in the interior of an iron made container, by sealing an aqueous solution of a molybdate as a working fluid in the container. CONSTITUTION:A stainless steel, a carbon steel or the like is used as a material for the container of a heat pipe. An aqueous solution of an alkali metal salt of molybdic acid, an alkaline earth metal salt of molybdic acid or the like is used as a working fluid, and a dense anti-corrosion film excellent in corrosion resistance is formed on the inside surface of the container.

IPC: H03K19/0948
Filed: 1987-07-24
Abstract: PURPOSE:To obtain a logic circuit with less noise disturbance onto an analog circuit by providing a means not giving a through-current to a P-channel MOS transistor (TR) of an output driver and an N-channel MOS TR to a pre-stage of the output driver circuit and suppressing the peak current of charging/ discharging from the load capacitance. CONSTITUTION:When a level of an input terminal I changes from '1' to '0', the output of a NAND 3 changes from '0' to '1' and a P-channel MOS TR Pch1 changes from ON to OFF. Similarly, the P-channel TR Pch2 changes from ON to OFF after a prescribed time through delay inverters 5, 6 and a P-channel MOS TR Pch3 changes from ON to OFF after a prescribed time through delay inverters 7, 8. Then the output of the delay inverter 4 changes from '1' to '0' and the output of the NOR 1 changes from '0' to '1'. The N-channel TR Nch1 is turned on and a load capacitance CL is being discharged. Thus, the noise of the peak current due to the charge/discharge from the load capacitance is prevented.

Title: Positioning carriage for magnetic disk device
Inventor: KORIYAMA HIROSHI
IPC: G11B21/02
Filed: 1987-07-24
Abstract: PURPOSE:To surely hold an arm even at the time of rapid seaking of a carriage and to completely removing a relative shear between a servo head and a data head by removing the plastic deformation of a draw bolt and interrupting the rotation of the bolt in its circumferential direction. CONSTITUTION:The arm 1 is connected to the draw bolt 2 by fixing the bolt 2 on a housing 1 and then engaging the bolt head part 7 of the bolt 2 with a window part 3 of the arm 1 so that the taper faces 10, 10 of the bolt head part 7 are abutted upon the tape faces 5, 5 of the window part 3. Since the draw bolt 2 has no notched part, the bolt has sufficient strength and is not plastically deformed. Since the parallel faces 6, 6 of the arm 1 are respectively abutted upon the parallel faces 9, 9 of the draw bolt 2, the bolt 2 is not almost rotated in the circumferential direction. Even if the carriage is rapidly moved, the arm 1 is not moved and the relative shear between the servo head and the data head can be removed.

Title: Silicon nitride film
Inventor: KONUMA TAKAYUKI
IPC: H01L21/302
Filed: 1980-12-29
Abstract: PURPOSE: To deposit metallic films of uniform thickness at the edge parts of silicon nitride layers by forming the silicon nitride layers provided on a substrate to two layered construction of a lower layer of a low rate of etching and an upper layer of a high rate of etching.  
     CONSTITUTION: In multilayered wiring or the like of a semiconductor device, a metallic wiring 3 is deposited via a silicon oxide layer 2 on a silicon substrate 1. Further, a lower layer silicon nitride film 41 of about 1μm film thickness and an upper layer silicon nitride film 42 of about 0.1μm film thickness are laminated on this, and the rates of etching are made higher with the film 42. Thence, photoresist 6 of prescribed patterns is provided on these and etching is carried out. Since the rates of etching of the film 42 and the film 41 differ, a taper is produced in the film 41 by the etching liquid penetrating through a window 5. Therefore, when a metallic film 7 is vapor deposited on this, the formation of an extremely thin part in film thickness on the film 7 is obviated, and the possibility of disconnection is eliminated.

IPC: B41F7/26
Filed: 1990-07-16
Abstract: PURPOSE: To obtain a smooth plate, especially a plate without lines of a gear profile by moving a loose gear by means of a gear transmitting rotational movement to a distributing roller. CONSTITUTION: A water distributing roller 3 is rotationally driven by a plate cylinder 1 through gears 6 and 7 and the second gear 9 for transmitting a reciprocating movement in the transverse direction to the water distributing roller 3 is rotationally moved by means of the first gear 8 fixed on a supporting leg 15 of the water distributing roller 3. When force is transmitted like this in the driving mechanism of the water distribution roller 3, even if a play is generated between gears by various different arrangements of the plate cylinder 1, a water damping roller 2 and the water distributing roller 3 and even if a slip is generated on the peripheral faces of the rollers caused by various different peripheral speeds and even if the damping roller 2 is penetrated into the cylinder channel of the plate cylinder 1, alternation of gear faces is avoided.  Therefore, there exists no possibility of generating a phenomenon wherein vibration generated by a driving apparatus gives lines of a gear profile which lowers quality of printing.
