Title: Semiconductor integrated circuit device
Inventor: MIWA HIDEO
IPC: H01L27/04
Filed: 1985-11-15
Abstract: PURPOSE:To improve the degree of integration while enlarging applicability by constituting an electrostatic breakdown preventive circuit of a Darlington bipolar transistor or a plurality of diodes connected in series. CONSTITUTION:An electrostatic breakdown preventive circuit II is composed of electronic devices, such as an NPN type bipolar transistor Tr1 and Darlington NPN type bipolar transistors Trd and a protective resistance element R. The transistor Tr1 is organized mainly so as to lead out negative overvoltage lower than threshold voltage (approximately -0.8[V]) between a collector region and a base region. Since the threshold voltage of each transistor Tr2-Tr5 extends over approximately 0.8[V], the transistors Trd are constructed so as to lead out positive overvoltage higher than supply voltage Vcc (a value 8.2[V] acquired by adding threshold voltage 3.2[V] to 5.0[V]). Accordingly, the electrostatic breakdown preventive circuit II can be applied to a TTL having an input standard of voltage such as -0.5-7.0V.

Title: Low-noise converter
Inventor: OIKAWA KAZUMASA
IPC: H05B41/285
Filed: 1993-09-20
Abstract: PURPOSE:To make the rise and fall of an output forming waveform smoother so as to remarkably reduce external noise by using two sets of complementary transistor circuits which are not turned on simultaneously. CONSTITUTION:When a load circuit is connected to the secondary-side terminal of an output transformer, transistors Q1 and Q4 and Q2 and Q3 are turned on only when electric currents IB1 and IB2 respectively flow to the transistors Q1 and Q4 and Q2 and Q3. As a result, electric currents IC1 and IC2 respectively flow to the transistors Q12 and Q4 and Q2 and Q3 from a positive bias power supply +Vcc. In addition, the waveform appearing on the secondary side of the transformer becomes power amplifying waveform having a smooth rise and fall. Therefore, line noise, radiation noise, etc., can be reduced.

Title: Thermal transfer printing device
Inventor: HIROSE TOSHIMASA
IPC: B41J2/32
Filed: 1989-09-29
Abstract: PURPOSE:To improve transfer printing efficiencies by urging in advance a medium to be transferred in a width direction thereof as said medium is being moved before printing. CONSTITUTION:A transfer medium 6 and a medium to be transferred 8 are moved toward a heating element 2 of a thermal print head 1 and the medium 8 goes between a platen 4 and a press roller 9 before said medium is pressed against the heating element 2 by means of the platen 4 so that the medium 8 is pressed in its width direction, whereby fibers which are raised upward from the surface of the medium 8 are caused to lie down, with the result that smoothness of said surface is improved and then printing is conducted. And, even after transfer printing, restoring forces of fibers on the surface of the medium 8 are weak, whereby the fibers are prevented from rising up again, and the density of the fibers increases because the fibers lie down, accelerating thereby capillarity of molten ink. As a result, transfer printing efficiencies can be improved.

Title: Purification of n-substituted maleimide
Inventor: YAMAMOTO TOSHIHIDE
IPC: C07D207/448
Filed: 1993-10-13
Abstract: PURPOSE:To obtain a high-purity N-substituted maleimide by direct distillation under specified conditions of an acid catalyst-contg. N-substituted maleimide reaction liquor and make the still residue liquor after distillation repeatedly usable as an acid catalyst. CONSTITUTION:A crude N-substituted maleimide is first obtained by reaction between maleic anhydride and a primary amine using an aromatic sulfonic acid as acid catalyst. The resultant acid catalyst-contg. crude reaction product is then subjected to direct distillation to obtain the objective purified N- substituted maleimide. Specifically, the production method is as follows: an aromatic hydrocarbon azeotropic with water is used as solvent; the number of moles of the primary amine to be used satisfy the relationship (SA is number of moles of the aromatic sulfonic acid; MAn is number of moles of the maleic anhydride; X is number of moles of the primary amine); the water produced during the reaction is removed by azeotropic process; the reaction is carried out while maintaining the reaction system as a homogeneous phase followed by direct distillation without separating and removing the acid catalyst. With this method, the objective high-purity N-substituted maleimide can be obtained in high yield, and, in addition, no wastewater treatment is needed.

Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a ceramic composite sintered compact, which is capable of preventing lowering in strength of the sintered compact by uniformly dispersing at least two kinds of particles and eliminating heterogeneous aggregate parts. SOLUTION: In a method for producing a ceramic composite sintered compact, which comprises drying a slurry containing at least two kinds of ceramic particles different in the density and/or the particle size to obtain dried particles, thereafter forming the dried particles and sintering the formed green body, the ceramic particles are allowed to previously and uniformly aggregate in the slurry by controlling the absolute value of zeta potential of the ceramic particles to be not more than 50 mV, preferably 25 mV. Thereby, it becomes possible to allow the ceramics different in the density or the particle size to uniformly complex, and the heterogeneous aggregate parts in the texture of the sintered compact are avoided. Accordingly, the strength of the ceramic composite sintered compact can be enhanced.

Title: Wire dot printing head
Inventor: ANDO KOICHI
IPC: B41J2/28
Filed: 1988-10-13
Abstract: PURPOSE:To obtain a wire dot printing head prevented from an increase of a driving current by arranging a permanent magnet at the center to form a magnetic circuit from the permanent magnet, a magnet yoke, an armature, a core and a core yoke. CONSTITUTION:A core plate 22 and a magnet yoke 23 are connected to the permanent magnet 21 arranged to the central part of a head. The core plate 22 is provided vertically and a demagnetizing coil 25 is wound around a core 24. The magnetic flux generated from the permanet magnet 21 arranged to the central part of the head passes through the magnet yoke 23 and the first acting gap with a biasing leaf spring 27 to enter an armature 29 and passes through the second acting gap 32 and the core 24 in the same way to return to the permanent magnet. Since there is no first yoke, the magnetic resistance between adjacent magnets 33, 34 becomes high. As a result, the quantity of the demagnetizing flux 35 generated in the demagnetizing coil 25 of the magnet 33 to flow in the adjacent magnet 34 is reuded to a large extent. Therefore, the magnetic interference between the adjacent magnets is reduced to a large extent and a wire dot printing head prevented from an increase of a driving current is obtained.

Abstract: PURPOSE:To prevent erroneous detection due to the dispersion of density of a platen cover (coloring member) by providing a density correction means to multiply or add a prescribed value set based on the dispersion of density of the coloring member on an image signal with only a color of coloring member, and to correct the image signal with density exceeding a threshold value based on the proper density of the coloring member to the threshold value. CONSTITUTION:An arithmetic circuit 100 inputs Y data(image signal with only the color of coloring member), a parameter P1', and the prescribed value set based on the dispersion of density of the coloring member in pre-scan, and corrects the reduction of the Y data due to the dispersion of density of the coloring member. Concretely, the Y data reduced due to the dispersion of density of the coloring member can be raised up by applying the multiplication of the Y data by a parameter P1, and also, the Y data when it exceeds 63 (threshold value) is outputted after it is arranged to 63. At such a case, the setting of the threshold value at 63 is performed so as to input image density 2 in 64 gradations (0-63 gradations) when an image is inputted and to input the proper density of the coloring member at a value 63 in advance.

Abstract: PURPOSE:To improve the responsiveness in output control for the sharp load variation by using a means for directly increasing and decreasing the combustion quantity according to the sharp variation signal of load and carrying out the air-fuel ratio control by the load evaluation signal corresponding to the load increase/decrease rate. CONSTITUTION:The heater 2 of a Stirling engine 1 absorbs the combustion heat in the continuous combustion of the mixed gas consisting of the air passing through a combustion air preheater 3 and the fuel supplied from a fuel nozzle 4, in a combustion chamber 5.
