Title: Wiring formation
Inventor: SASAKI MASAYOSHI
IPC: H01L21/3205
Filed: 1990-05-25
Abstract: PURPOSE:To form a wiring in excellent coverage by a method wherein ultrafine particles comprising a conductive material are deposited on a substrate in the no-heated state and then heated later to form a conductive part comprising a conductive material. CONSTITUTION:A wafer as a substrate 1 is cooled down at the temperature not exceeding the room temperature and then Al ultrafine particles are deposited to form a layer thereof on the substrate 1. Thus, even a recession 3 can be filled up with the ultrafine particles 5 evenly and completely. After the deposition, the Al ultrafine particles are sintered by heating the wafer af the substrate 1 so as to form an Al layer as a conductive part 6. Through these procedures, the conductive part 6 (Al layer) can be formed if necessary taking a specific shape into the wiring of an LSI.

Title: Secondary-electron emitting cold cathode
Inventor: IKEDA JUNJI
IPC: H01J1/32
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To provide a thin-film cold cathode of the type emitting secondary electrons. SOLUTION: An insulation film 2 is formed on an insulator substrate 1, and a sharpened thin-film cathode 3 is formed on the insulator 2. In a position spaced apart from this layered body, a thin-film anode 4 is formed on the insulator substrate 1. When a gate voltage is applied between the thin-film cathode 3 and the thin-film anode 4 so as to positively polarize the thin-film anode 4, an electric field is concentrated on a sharpened field concentration part 7, and electrons in the thin-film cathode 3 are emitted into a vacuum by a quantum mechanical tunnel effect. Primary electron beams 5 emitted from the thin-film cathode 3 are accelerated toward the thin-film anode 4 by the voltage applied between the thin-film cathode 3 and the thin-film anode 4, thus irradiating the thin-film anode 4. This causes secondary electron beams 6 to be emitted from the thin-film anode 4.

Title: Semiconductor device and manufacture thereof
Inventor: MAEGUCHI KENJI
IPC: H01L21/225
Filed: 1984-07-02
Abstract: PURPOSE:To contrive the micro fabrication, speed up, and high reliability of element by a method wherein the region in contact with a field inversion preventing layer is reduced by forming source and drain regions very shallowly. CONSTITUTION:Impurity regions 1031 and 1032 to form the inversion preventing layer under a field oxide film are formed by ion implantion of a P type impurity to both sides on a P type Si substrate 101, thus forming the field oxide film 104 which isolates the element region in island form. Next, a gate oxide film 105', a gate electrode 106' of a polycrystalline Si film, and a pattern 107' are formed; thereafter, an oxide film 109 is deposited over the whole surface and then left only on side surfaces by etching. Further, a polycrystallined Si layer is grown to the level of the electrode 106', and a single crystal Si layer 110 and N<+> type source and drain regions 111 and 112 are formed by introducing phosphorus. Al wirings 1151 and 1152 are formed after removal of the pattern 107'.

Title: Amorphous core for common mode choke
Inventor: YOSHIZAWA KATSUTO
IPC: C22C19/07
Filed: 1985-06-25
Abstract: PURPOSE:To obtain an amorphous core for common mode choke, which is superior in frequency characteristics at the absolute value of permeability to a ferrite core for common mode choke and is superior in stability with time as well, by a method wherein an amorphous alloy having a specific composition is used as the material for the amorphous core for common mode choke. CONSTITUTION:An amorphous alloy having a composition, which is shown by a compositional formula =(Co1-a-bFeaMnb)100-x-y-zMxSiyBzX) (where the M is at least one kind of an element to be chosen out of the group of Ti, Zr, Hb, V, Nb, Ta, Cr, Mo, W, Ni and Cu) and has the relations of 0<=a<=0.10, 0.01<=b<=0.10, 1<=x<=8, 12<=y<=18 and 8<=z<=9.5 [the (x), the (y) and the (z) each shows an atomic ) is used as the material for the amorphous core for common mode choke. The Mn is essential in the composition and has an effect of making smaller the variation with time, and at the same time, has an effect of making larger the absolute value of permeability, but when the composition ratio (b) of the Mn is not more than 0.01, the above mentioned effects are not sufficient and when the composition ratio (b) exceeds 0.10, the core material becomes easy to embrittle and the manufacture of the amorphous alloy becomes difficult, so the composition ratio (b) is set at the ratio of 0.01<=b<=0.1. The composition ratio (a) of the Fe must be within an range of 0<=a<=0.1. When the (a) exceeds 0.1, the magnetic properties deteriorate as the magnetostriction increases. So it is not desirable to exceed 0.1. Accordingly the (a) shall be 0.1 or less. An amorphous alloy ribbon having a board thickness of 20mum or less among the amorphous alloy ribbons, which are the material for the amorphous core, is especially suitable for the use for the core for common mode choke..

Title: Device and method of equalizing and grinding tire
Inventor: JIYON DABURIYU UGO
IPC: B24B49/16
Filed: 1984-07-02
Abstract: Apparatus for improving tire uniformity includes contra-rotating grinding wheels (32, 34) for removing tire material from the upper and lower shoulder portions of the tire (16). The grinders are moved on an assembly (18) into grinding engagement with the tire along a path that is defined by a radius of the tire to ensure that both grinding wheels at each shoulder of the tire make simultaneous contact with the tire. The amount and extend of grinding accomplished by the contra-rotating grinders is controlled by a grind control circuit. The grind control circuit measures the no-load current level of the grinder motor and compares the no-load current level with the current level when the grinder motors are under load. When the grinder current under load is above a predetermined maximum load current, the control circuit will signal the grinders to retract from engagement with the tire until the load current drops below the predetermined maximum level. When the motor load current is below the minimum operating range level, the grinders are signalled to advance into engagement with the tire until the load current reaches the predetermined minimum level. This operations is repeated in cyclic fashion until the tire has been ground a sufficient amount to bring it within an acceptable correction range. An alarm circuit which cooperates with the grind control circuit assures that once a grinding operation is begun it will have a predetermined minimum time duration. The alarm circuit also detects whether one of the shoulder grinders takes too long to engage the tire after the other shoulder grinder has made such engagement. The alarm circuit will stop the grinding operation if too long a period of time has elapsed and if there are other malfunctions of the grinders.
