Title: Electronic device
Inventor: SHIMIZU KAZUO
IPC: H01L23/28
Filed: 1986-05-23
Abstract: PURPOSE:To improve the water resistance of electronic device as well as the adhesive property between a sealing body and heat dissipating plates while expanding the surface area of heat dissipating plates by a method wherein fine rugged parts are formed on the positions where the heat dissipating plates formed into one body with a semiconductor chip fixing tab are brought into contact with the sealing body. CONSTITUTION:The sectional surface of rugged parts 5a, 5b are formed into fine irregularities. When these rugged parts 5a, 5b are sealed up in a sealing body 11, the resin material used as the sealing body 11 permeates into the rugged parts 5a, 5b so that the adhesive property of both parts 5a, 5b may be improved while expanding the surface area of heat dissipating plates 3a, 3b. Resultantly, any water content entering in the arrow C direction can hardly reach a semiconductor chip due to the improved adhesive property of rugged parts 5a, 5b as well as the expanded distance of water permeating channel by the rugged part 5a.

Abstract: PROBLEM TO BE SOLVED: To solve the problems of damage to an equipment and the shortage of heat in molten iron during the refining in a converter by using slag produced in the other decarburize-refining and/or dephosphor-refining for a molten iron treatment-reacting vessel for executing the desiliconizing treatment and/or dephosphorizing treatment of the molten iron. SOLUTION: In the molten iron treatment-reacting vessel 1, the molten iron 2 to be treated with the desiliconizing or dephosphorizing and the necessary slag 3 are charged. Gas 5 for stirring is blown into the molten iron 2 from an immersion lance 4, and while stirring the molten iron 2 and the slag 3, gaseous oxygen 7 is top-blown near the surface of the slag 3 and the molten iron 2 from a top-blowing lance 6 to execute the siliconization and the dephosphorization in the molten iron 2. When the desiliconizing or dephosphorizing treatment is executed to the molten iron 2 tapped from a blast furnace, the decarburized slag 8 already used for the decarburize-refining and/or the dephosphorized slag 9 already used for the dephosphorizing treatment are added into the treatment-reacting vessel 1.  In this way, the slags 8, 9 are fluidized, and the slag 3 is diluted and the content of SiO2 or P2O5 in the slag 3 is lowered and their activities are lowered.

Filed: 1986-05-22
Abstract: PURPOSE:To obtain an optimum index signal and to detect a correct electrom beam position by commonly or independently forming index stripes correspondingly to respective fluorescent material stripes in an area narrower than the fluorescent material stripe. CONSTITUTION:In an area narrower than the fluorescent stripes R, G, B, a first-a third index stripes I1, I2, I3 including short decay fluorescent materials having different light emitting wavelength are formed correspondingly to the respective fluorescent material stripes R, G, B.

Title: Magnetic card identifying method
Inventor: SUGANO TOMOSHI
IPC: G06K19/00
Filed: 1988-05-17
Abstract: PURPOSE:To effectively prevent the use of a forged magnetic card by comparing first reproducing output in which the data of a magnetic card is reproduced with second reproducing output in which the data of the magnetic card is reproduced after a transferring magnetic field is applied on the magnetic card, and recognizing the card as a normal magnetic card based on the compared result. CONSTITUTION:The data of the magnetic card is reproduced by a recording and reproducing head 4, and the reproducing output at this time is called as the first reproducing output. Next, when the transferring magnetic field is applied on the magnetic card, the data is transferred on a layer 3 with a low coercive force in case of using the normal magnetic card. After that, the data of the magnetic card is reproduced again by the recording and reproducing head 4, and the reproducing output at this time is called as the second reproducing output. When the second reproducing output is compared with the first reproducing output, the former is remarkably larger than the latter in case of using the normal magnetic card. In such a way, by recognizing only the magnetic card when the second reproducing output is larger by a constant quantity than the first reproducing output as the normal magnetic card, the normal magnetic card can be identified from the forged magnetic card.

Abstract: An audible tone identifier comprises a transducer and amplifier for responding to audible tones, such as generated by a human voice speaking or singing, or a musical instrument, and a plurality of filters sharply tuned to the notes of one or more octaves or fractions thereof of the equal tempered chromatic musical scale or to other patterns of sounds that are to be individually identified. The outputs of the filters are connected to lamp driver circuits which in turn are connected through transposing plug-and-jack connectors and sharp-and-flat insertion switches to lamps on a display board, whereby any musical tone within the range of the device, received by the transducer, will be identified visually on the display board by the lighting of a lamp. The tone identifier may be a component of a teaching or speech therapy system including a source of recorded instructions and sounds to be produced by a trainee, such as a tape player and pre-recorded tape, and headphones through which the trainee hears instructions as well as the sounds produced by him. The relative conformity of tone frequencies with the center frequency of the filters is indicated by comparing the phase of said waves at the input and output of the filters.

Filed: 1984-06-08
Abstract: PURPOSE:To improve the surge withstand capacity by providing a surge protective circuit in the input or output circuit part of a semiconductor integrated circuit device produced with the ECL (Emitter Coupled Logic) process. CONSTITUTION:When a positive-polarity surge is impressed to input terminals 3 and 2 in the input circuit part, surge passing routes from input terminals 2 and 3 to a power supply terminal 1 are formed by protective clamp diodes 13 and 15. Thus, the destruction of insulating films and PN junctions of transistors TRs 6 and 5 is prevented. When a negative-polarity surge is impressed, surge routes from a ground terminal 4 to input terminals 2 and 3 are formed by diodes 14 and 15. Thus, the destruction of TRs 6 and 5 is prevented. Consequently, the surge withstand capacity is improved. When protective clamp diodes are provided in the output circuit part, the similar effect is attained.
