Title: Wire binding method
Inventor: MATSUKURA TAKUMI
IPC: H01L21/60
Filed: 1991-11-12
Abstract: PURPOSE:To prevent short-circuit generated between a bonding wire and the terminal part of a semiconductor chip or between the bonding wires, by controlling the loop shape of the bonding wire through moving a bonding tool arbitrarily in a horizontal direction. CONSTITUTION:The electrode pad of a semiconductor chip and an inner lead are used respectively as first and second connective points P1, P6, and a wire bonding is applied to them. A point P5 is located apart from the line, by which the points P1, P6 are connected, in a horizontal direction by an arbitrary distance. In the case of this wire bonding, while passing the point P5, a bonding tool is moved from the starting point P1, to the terminal point P6. By making the bonding tool trace such a locus, a bonding wire is deformed in the horizontal direction and the loop shape which is projected on a horizontal plane by the bonding wire is controlled arbitrarily.

Title: Bidirectional 2-pole thyristor
Inventor: OTA KOICHI
IPC: H01L29/861
Filed: 1989-11-14
Abstract: PURPOSE:To obtain a bidirectional 2-pole thyristor which can be mass-produced stably with a high yield rate and has a large withstanding current for a surge by providing a region in which the overlapping distance of P (N) layers is relatively small in comparison with the one of the other region in the overlapping part of P (N) layers on both surfaces of the thyristor. CONSTITUTION:While the overlapping width of a P1 and P2 layer in a usual thyristor is d over the whole length of an overlapping part, a region C in which the overlapping width shown as d' is made to be small is locally provided in the central region part of the element and in this region, and the distance in the lateral direction between an N1 and N2 layer is shortened by (d-d'). Thereby, the positional distributions of current amplification factors alphaN, alphaP become the ones in that (alphaN+alphaP) expressing a turn-on condition is forced to exhibit a maximum peak concentrated near the region C and this corresponds equivalently making base widths WN and WP small. Therefore, the withstanding current for a lightning surge can be improved decreasing an electric power loss in a turn-on region.

Title: Thin film transistor
Inventor: ONO SEIJI
IPC: H01L29/78
Filed: 1992-11-05
Abstract: PURPOSE:To prevent conduction electrons and holes produced in insulating films from being diffused into an active layer by so constituting a thin film transistor consisting at least two layers of insulating films that the first insulating film has a wider forbidden band with than the second, formed outside the first, does. CONSTITUTION:Each of a protective insulating layer 2A and gate insulating layer 2B consists of three layers: second insulating film 22 and 23, first insulating films 25 and 28, and third insulating film 26 and 27. When energy hnu is externally applied to the TFT, the conduction electrons 32 and holes 31 cannot diffuse into a semiconductor active layer 29,because of the first insulating films 25 and 28 having a wider forbidden band width. On the other hand, pairs of electrons and holes produced in the first 25 and 28 and third 26 and 27 insulating films are far smaller than the thickness of the second insulating films 22 and 23; therefore, most of them are prevented from diffusing into the semiconductor- active layer 29.

Title: Method to generate abbreviated expression of bit group
Inventor: PATEL SARVAR
IPC: G09C1/00
Filed: 1999-10-18
Abstract: PROBLEM TO BE SOLVED: To efficiently hash a string by squaring the sum of a key and the string to be hashed. SOLUTION: An input string or a message m is inputted (S100). Then, an input key a is inputted. Each of the message or a string m and the key a consists of w words and has an n bit length. The key a is a random number or a pseudo-random number and it can be longer than n bits, however, it is desirable to have n bits (S102). Then, a sum s of the string m and the key a is taken, and squared to execute a rule p operation where p is a first prime number larger than 2n (S106 and 108). A rule 2l operation is executed for the result of the operation where 1 is a short output message for the bit number in the string (110). Then, the result of the rule 2l operation is outputted. Thus, the message having n bits or the string, which is made into an l bit message or the message that is reduced to a string, is obtained (S112).

Inventor: NARAHARA TAKEFUMI
IPC: C21D1/667
Filed: 1989-11-14
Abstract: PURPOSE:To prevent the generation of bending of a pipe at the time of hardening by regulating the air pressure to be supplied to piston-cylinders to regulate the force by which water feed nozzles are brought into pressurized contact with the pipe end and to allow the nozzles to follow up the contraction of the pipe. CONSTITUTION:The water feed nozzles 2 are first pushed out by air cylinders 4 up to the first pipe end position in the case of feeding of water to the inside surface of the pipe for the purpose of hardening. The water feed nozzles 2 are pushed out to the pipe end 6a by guide rods 5 and the position where the nozzles come into contact with the pipe end 6a is determined as the rod end. The water feed nozzles 2 are so adjusted as not to be extruded from this position. The force that the water feed nozzles 2 receive when the flowing water is throttled during the feeding is absorbed by the guide rods 5. On the other hand, the piston-cylinders 2a follow up the contraction of the pipe 6. The force by which the piston cylinders 2a are brought into pressurized contact with the pipe end 6a is regulated by regulating the air pressure supplied from a pump to air chambers 7.

IPC: G06F13/362
Filed: 1990-11-01
Abstract: PURPOSE:To shorten the access time by obtaining a common bus, when it is informed to a processor from a bus arbitrating circuit that the arbitration is unnecessary. CONSTITUTION:When a request signal is received to a processor 1 and input/ output controllers 2, 3 from a bus arbitrating circuit 5 through bus use request signal lines 10, 11 and 12, a permitting signal is applied through use permitting signal lines 13, 14 and 15 with respect to a use request whose priority is the highest by a bus arbitrating part 6. When devices 2, 3 are not outputting a bus use request signal, when there is a use request signal from the processor 1, the circuit 5 applies a permitting signal to the processor 1 through a processor bus permitting signal line 16, and by this signal, the respective signals are outputted through an address signal line 17, a command signal line 19, and a data signal line 18. In such a way, when a bus use request does not compete, the access time to a main storage device and the input/output controller from the processor can be shortened.
