Title: Preparation of antisense nucleic acid
Inventor: UCHIDA KIYOSHI
IPC: C07H21/04
Filed: 1997-05-20
Abstract: PROBLEM TO BE SOLVED: To efficiently obtain an antisense nucleic acid for medicines, etc., by numerically converting the extent of possibility of the complementary double chain formation between a region of base sequence of mRNA and a region other than the base sequence in each region of base sequence of mRNA and preparing a complementary nucleic acid in a region which is low in numerical value. SOLUTION: The extent of possibility forming a substantially complementary double between a region of base sequence of mRNA and other region different from the above region in each region of a base sequence of mRNA is converted to a numerical value based on a fact that the extent of possibility forming the double chain is maximum when a distance between substantially complementary base sequences holds 3-10 bases or the extent of the possibility is converted into a numerical value based on the fact that a binding energy in forming the double chain becomes a numerical value calculated based on the closest base pair model or the extent of the possibility is numerically converted based on above both facts and a nucleic acid having a base sequence substantially complementary to a region low in the numerical value is prepared as an antisense nucleic acid to efficiently provide the  objective antisense nucleic acid used for antisense nucleic acid method useful for preparation, etc., of a medicine or a gene recombinant plant.

Title: Logarithmic if amplifier circuit
Inventor: KIMURA KATSUHARU
IPC: H04B17/00
Filed: 1986-06-04
Abstract: PURPOSE:To realize a logarithmic IF amplifier by using a transistor (TR) different in emitter size connected to the input/output of a differential amplifier of the n-th stage and differential amplifiers of each stage, connecting m-set of differential pairs in parallel each while an emitter resistor is connected and adding collector currents of the TRs small in emitter size. CONSTITUTION:The differential amplifier of 1st stage comprising TRs Q1, Q1', resistor R1, R1' and a constant current source I1 amplifies an input signal VIN, the output goes to an input signal of the 2nd stage being the next stage, and the signal is amplified sequentially and the output of the differential amplifier of the n-th stage goes to an IF output signal VOUT. On the other hand, the differential pair group connected in parallel by mi-set each from the 1st to the (n+1)th stage receives the input/output signal of the differential aplifiers respectively from the said 1st stage to the n-th stage. For example, TRs Q11, Q11' as to the differential pair group of the (m-1)th stage have the emitter size of 1:k11 (k11>1), and the emitter size is 1:k1m1 (k1m1>1) as to TRs Q12m1-1, Q12m1-1. In selecting the emitter size of TRs constituting a differential pair properly, its output current I0 is approximated logarithmically with respect to an input signal VIN.

Title: Digital/analog converter
Inventor: SUGANO HIROSHI
IPC: H03M1/10
Filed: 1987-05-27
Abstract: PURPOSE:To reduce the distortion produced at the time of small signals, by constituting a digital/analog (D/A) converter of a constant multipier and constant adder, which make digital operations, D/A converter, and band-pass filter. CONSTITUTION:This D/A converter is constituted of a constant multiplier 2 and constant adder 3, which make digital operations, D/A converter 4, and band-pass filter 5. The constant multiplier 2 multiplies digital signals inputted from an input terminal 1 by a constant and the constant adder 3 adds a DC offset to the digital signals. Then the D/A converter 4 performs D/A conversion on the output of the adder 3, but, since the digital signals have the offset and the signals after the offset do not cross the bipolar-zero point of the D/A converter 4, large distortion is not produced. Therefore, the distortion produced at the time of small signals can be made smaller.

Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor device in which an underfill resin can be prevented from peeling off by reducing warping of an insulating substrate when the underfill resin between a semiconductor chip and the insulating substrate is cured, and a manufacturing method thereof. SOLUTION: In a semiconductor device in which a semiconductor chip 12 is flip-chip mounted on a resin substrate 11 through a underfill resin 19, the length of a fillet 20 formed on the side edge face of the semiconductor chip 12 by implanting the underfill resin 19 is made longer than the distance between the surface of the resin substrate 11 and the rear side of the semiconductor chip 12.

CONSTITUTION:A thermal oxide film 12 is shaped onto the whole surface of a P<-> type semiconductor substrate 11 to which an N<+> type buried layer must be formed, the thermal oxide film 12 on a region in which the N<+> type buried layer is shaped is etched selectively, and the partial surface of the P<-> type semiconductor wafer 11 is exposed. It is assumed that there are foreign matters 13 as the nuclei of devitrifiaction on the thermal oxide film 12 at that time. The oxide or chloride of antimony or arsenic is diffused into a specified region through the method of application, a gas diffusion method, etc., thus shaping the N<+> type layer 14. On the other hand, a devitrification section is formed to the thermal oxide film 12, using foreign matters 13 as nuclei, and an N<+> type diffusion layer 16 in a region not specified in the P-type semiconductor substrate 11 is diffused through the cracks of the devitrification section. The surface is inspected, removing approximately 20 or 50% of the film thickness of the thermal oxide film 12 of the whole wafer.

Abstract: PURPOSE:To produce steel strips having excellent surface characteristics in good material yields in the stage of producing the steel strips by hot rolling and cooling the ingots after heating the same to rolling temp. in a nonoxidative or in a slightly oxidative atmosphere. CONSTITUTION:The ingot sheet 4A cast continuously with a sheet caster is cooled down to hot rolling temp. in a nonoxidative state and while the sheet receives light screwing-down with sealing rolls/continuous casting pinch rolls 6, the sheet enters a hot rolling chamber 8 in a nonoxidative or slightly oxidative atmosphere. Since the atmospheric pressure in the chamber 8 is slightly larger than atmospheric pressure, the sheet is hot rolled without the entry of the oxidative atmospheric air from the outside and without oxidation of the surfaces with roughing mills 12 and finishing mills 14. The strip enters the inside of a cooling chamber 16 in a nonoxidative or slightly oxidative atmosphere of further larger atmospheric pressure, where the strip is cooled in a cooling zone 18 and is coiled with a coiler 20; thereafter the coil is cooled down to an ordinary temp. in a delivery chamber 22 in a nonoxidative or slightly oxidative atmosphere.
