Filed: 1990-03-29
Abstract: PURPOSE:To form a high speed packet transmission network with much flow of packet information by comparing transmission quantity of a packet with a prescribed value inputted to a comparator circuit and sending the packet when the quantity of the packet is discriminated to be less than the prescribed value. CONSTITUTION:A packet signal is inputted from an input terminal 1 based on a packet transmission request and stored in a storage circuit 8.

Title: Non-volatile semiconductor memory device
Inventor: HASUNUMA SUSUMU
IPC: H01L29/788
Filed: 1984-04-25
Abstract: PURPOSE:To improve the dielectric withstanding capability of an insulating film and to obtain excellent non-volatile semiconductor memory device leading to the production of high-reliability devices with a high acceptable rate by a method wherein the thin gate insulating film region just under a floating gate is provided not adjoining a field insulating film region. CONSTITUTION:On the surface of a P type semiconductor substrate 11, a field oxide film 12 and a thin oxide film 13 are formed and, through the latter, As ions are implanted for the formation of an N type buried layer 14. Next, the oxide film 13 is removed by using F or the like. A process follows wherein thermal oxidation, patterning of a resist, partial removal of the oxide films, and second thermal oxidation are accomplished for the formation of a relatively thin first insulating film 15 and a relatively thick second insulating film 16. The first, insulating film 15 is not in contact with the field oxide film 12. Next, a floating gate 17, gate oxide film 18, control gate 19 are built for the completion of the required memory device. In a device wherein the gate is a lamination of the two insulating films 15, 16 greatly different from each other in thickness, a current flows in the thinner insulating film 15 generating a stronger electric field. This results in a memory device with its insulation not to be easily broken down due to pinholes and other defects.

Title: Production of magnetic head core for high frequency
Inventor: KOMATA YUJI
IPC: H01F10/12
Filed: 1987-04-03
Abstract: PURPOSE:To decrease the influence of boundary strains and to eliminate the need for a fresh vapor deposition source material as nonmagnetic insulating layers by using the same vapor deposition source as the vapor deposition source for the material of magnetic layers and using compd. films deposited by evaporation in an atmosphere contg. reactive gases to constitute the nonmagnetic insulating layers. CONSTITUTION:An amorphous alloy essentially consisting of a Co-Nb system is used for the magnetic layers 1. The films which are formed by sputtering vapor deposition using the same sputtering target mixed with gaseous N2 in gaseous Ar and contain cobalt nitride and niobium nitride are used as the nonmagnetic insulating layers 2. The magnetic layers 1 and the insulating layers 2 are laminated alternately 10 times to obtain a magnetic head core 3. The influence of the boundary strains on soft magnetic characteristics is decreased in such a manner and the laminated structure which takes advantage of the effect of preventing an eddy current loss in a high frequency range is produced by utilizing only the single vapor deposition source while the deterioration in the soft magnetic characteristics mainly in a low frequency range is suppressed.

Filed: 1983-05-12
Abstract: PURPOSE:To save a material, etc. and make the cost reduction possible, by omitting a polishing step for finishing in producing a clutch facing by impregnating an asbestos cloth, etc. with a synthetic resin and a rubber solution one after another, drying the impregnated asbestos cloth, etc., and post-treating the resultant base material.

Only when the thickness accuracy is insufficient for the specified value, a nonfrictional surface is roughly ground to produce the aimed clutch facing. EFFECT:The deterioration of initial effect is improved due to frictional surface left in after-cured state, and the cohesion to an opposite material with rust is prevented by no exposure of the asbestos yarns.

Title: Interruption controller
Inventor: KAWAKAMI TAKUYA
IPC: G06F9/46
Filed: 1997-03-17
Abstract: PROBLEM TO BE SOLVED: To provide the interruption controller which functions to autonomously set the priority order of interruption request signals outputted by I/O controllers where peripheral devices are connected according to the operation speeds of the connected peripheral devices. SOLUTION: A bus monitor circuit 2 detects bus access for setting speeds to the I/O controllers as generation sources of interruption request signals IRQ0 to IRQ3 by a CPU and sets set values S0 to S3 of detected speeds in speed registers 3-0 to 3-3 that the I/O controllers correspond to. A priority determining circuit 4 inputs the interruption request signals IRQ0 to IRQ3 and the speeds S0 to S3 set in the speed registers 3-0 to 3-3 to select the interruption request signal of the I/O controller with the highest speed among S0 to S3 preferentially when the interruption request signals IRQ0 to IRQ3 are generated at the same time and then set an interruption factor in an interruption factor register 5 that interrupts the CPU.

Title: Driving-controlling system for thermal serial printer
Inventor: YOSHIHARA TAKAO
IPC: B41J2/38
Filed: 1985-04-18
Abstract: PURPOSE:To enhance printing quality, by a system wherein dummy data for preheating formed from a recording pattern by calculation are sent to each current passing controlling circuit to perform preheating. CONSTITUTION:Immediately before n-th printing, the dummy data are sent to each of current passing controlling circuits 3-1-3-7, and when (n-1)th piece of printing data is '0' and n-th piece of printing data is '1', preheating is conducted. When the (n-1)th piece of printing data is '1' and the n-th piece of printing data is '1', preheating is not conducted, and heat accumulation is prevented. Heating time for dummy data is set to be shorter than that for normal printing data, whereby preheating is achieved. Accordingly, heat is still left when printing the n-th printing data, so that void is prevented from being generated. In addition, when the (n-1)th and n-th pieces of printing data are '1, 1', preheating is not conducted, whereby trailing due to overheating can be prevented from occurring.

Title: Superconducting magnet
Inventor: MITSUNE SUSUMU
IPC: H01F6/02
Filed: 1990-03-30
Abstract: PURPOSE:To quicken the decay time of a coil current which flows in a quenched part of a superconducting coil for preventing a burning of the quenched part by connecting by a lead wire a specified point on the superconducting coil at which the superconducting coil is electrically divided and a specified point on a protection resistor at which the protection resistor is electrically divided. CONSTITUTION:If a quench occurs on a part 4 of a superconducting coil 3 on one side from the center, a dc breaker 2 is opened and current flow to the superconducting coil 3 is stopped. A current flows in a parallel circuit composed of the superconducting coil 3 and a protection resistor 5 by energy stored in the superconducting coil 3. At this time, the current is divided into two from a lead wire 6; a current I1 which flows in the quenched coil and a current I2 which flows in the sound coil. A circuit in which the current I1 flows has a shorter time constant than the one in which a current I3 flows while a circuit in which the current I2 flows has a longer one than a circuit of the current I3. In the case that the electrically divided circuits are connected magnetically, the current I2 sometimes increases even more than the initial value by magnetic induction of the current I1. There is no problem if a current decay time is long since the current I2 flows in the quench-free coil.
