Patent JP-S57186369-A (JP)
Title: Semiconductor device
Inventor: FUJI TATSUO
IPC: H01L21/8247
Filed: 1981-05-13
Abstract: PURPOSE:To obtain a non-volatile memory storage having an excellent efficiency of erase and holding characteristic of memory by continuously reducing charge capture level density in an Si3N4 to the interface of a metal-Si3N4 from the interface of Si3N4-SiO2. CONSTITUTION:When charge density in an Si3N4 3 is uniform in an MNOS type FET, the center of the distribution of charge density captured exists at the Si3N4 side from the interface of SiO2 2 and Si3N4 3, erasing voltage applied to a gate 4 and gate width must be increased more than when the center of the distribution exists in the interface, and the efficiency of erase is inferior. Charges flow out to the gate 4 as far as the distribution of charges is not uniform under a condition that charges are held in Si3N4, and the holding property of memory is improved with the decrease of charge capture level density in Si3N4, but the cente of the distribution of charge density deeply intrudes into Si3N4, and the efficiency of erase degrades. According to this constitution, since a dielectric-constant discontinuous surface is not generated in Si3N4 and an electric field does not concentrate, dielectric breakdown is not generated at pulse voltage for injecting and discharging charges, and the non-volatile memory storage having excellent characteristics is obtained.

Title: Stay on tab type can lid and production thereof
Inventor: NAGAI KATSUMI
IPC: B21D51/44
Filed: 1994-04-11
Abstract: PURPOSE:To surely prevent the careless rotation or a tab on a panel by engaging a projection projected on the panel into an engaging hole of a tongue tip of the tab making the gradient of its circumferential wall within a specific range. CONSTITUTION:This lid has an opening score 5 impressed in an opening shape, an opening tab 3 to break this score and to open it, and a rivet to fixedly attaching the tab on a panel. A projection 9 upheaved nearby the rivet 2 of the panel 1 is installed, a rivet hole 30 in which the rivet 2 is inserted and fixedly attached onto a tongue tip 4 formed on an almost central part of the tab 3 and an engaging hole 10 engaging to the projection 9 nearby the rivet hole are installed. Because the gradient surrounding the projection 9 of this can lid is made 45 deg. to 90 deg., the tongue tip 4 is not ridden on the projection 9 when this tongue tip 4 and the engaging hole 10 are made in the engaging state, even if a large torque is applied on the tab 3. Therefore, the tab 3 is intercepted from rotating around the rivet 2, and the careless rotation of the tab 3 during operation of opening or in the time of producing the can.

Title: Conduit line aerial bus
Inventor: SUMIKAWA TOSHIO
IPC: H02G5/06
Filed: 1989-03-27
Abstract: PURPOSE:To relieve the stress by thermal expansion by fabricating a container of a long size conduit line bus with a material low in coefficient of linear thermal expansion and by fabricating a container intersecting perpendicularly thereto of a relatively short conduit line bus low in Young's modulus. CONSTITUTION:A long size bus bar 11 is made of Fe. A container 12 is made of Al to form a short bus. Here, if a bending stress deltaA generated to a point A is found, it will be deltaA<deltaP (allowable stress value), where the stress generated to the point A is remarkably lowered than in the case where both buses 11 and 12 are made of Al or Fe all in all. The stress will be lower than the allowable one deltaP of Al constituting the container of the short bus 12. Thus, the problem of the thermal expansion can be solved without providing a special device such as a bellow joint.

Filed: 1979-06-11
Abstract: PURPOSE:To improve reliability and make a structure small size and reduce the cost, by using a photoelectric element, where the wave length and the output voltage have proportional relation, for detection of infrared rays radiated from a thermal lump. CONSTITUTION:This detector receives infrared rays, which are radiated from thermal lump 1 of a detection material, by photoelectric element 15 and converts the optical signal to an electric signal to detect whether the thermal lump is present or not, and photoelectric element 15 outputs the output proportional to the wave length of radiated infrared rays, and this output is amplified by amplifier 6 and is input to operational amplifiers 13 and 13', and comparison voltage values VU and VL for the wave length by which the output above is filtered are set previously to compare them with the output. Thus, all wave length except the wave length of the light source issued from the thermal lump of the detection material are not output, so that a thermal lump detector strong against disturbance light can be obtained.

IPC: G11C19/08
Filed: 1980-05-30
Abstract: PURPOSE:To lower the probability of the occurrence of a transfer error by reducing electric power consumption by initiating the initial driving of a cylindrical magnetic domain from the center of a conductive layer slot. CONSTITUTION:When AC currents J1 and J2 with phases 11 and 12 differing by 90 deg. are applied to conductor layers 3 and 1 for driving a cylindrical magnetic domain equipped with overlapping slots 7..., and 6..., the cylindrical magnetic domain generates driving force and a composite magnetic field becomes a traveling wave. Then, when this cylindrical magnetic domain is generated from the center, etc., of the slots 6..., the cylindrical magnetic domain is affected by the maximum magnetism gradient and the driving force in initial driving is maximized. Therefore,  magnetic bubbles are transferred at a low rate of error occurrence with small currents and low power consumption.
