Title: Method for ink injection to ink cartridge
Inventor: HAIGO HIDEAKI
IPC: B41J2/175
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To contrive not to disperse bubbles in ink even though porous matter such as foamed material is present. SOLUTION: As ink injected into an ink cartridge is being heated approximately up to 40-50 deg.C at a deaerotion heating ink plant 56, it becomes highly liquid with less meltage of air when being absorbed into porous matter in the ink cartridge 2. Therefore, the ink flows uniformly into entire body of the porous matter without sucking air as in the case of being in highly viscosity. Consequently, the ink is filled in the porous matter with air in the porous matter forced out, and therefore bubbles do not remain in the porous matter with the ink. Accordingly, an ink jet printer using the ink cartridge 2 can maintain printing quality at a high level, printing failure due to bubbles can be prevented.

Title: Photosemiconductor element and optical bistable element
Inventor: SUGIMOTO MITSUNORI
IPC: G02F3/00
Filed: 1988-03-18
Abstract: PURPOSE:To enable high-speed operation while incident power is small by laminating respective required layers on a semiconductor substrate and satisfying the prescribed conditions with the energy Ew between the 1st levels of electrons and holes and forbidden band width Eg of the quantum well layer. CONSTITUTION:The resonance tunnel barrier structure consisting of an (n)-type clad layer 1, an (n)-type light guide layer 2, a 1st spacer layer 3, a thin 1st barrier layer 4, and the quantum well layer 5 having the forbidden band width narrower than the forbidden band width of the layer 4 and the photosemiconductor element of the similar conduction type laminated with a (p)-type barrier layer 6, a 2nd spacer layer 7, a guide layer 8, a clad layer 9, etc., are laminated on a GaAs substrate 10 to form the photosemiconductor element. The energy Ew and the width Eg are so selected as to satisfy the conditions expressed by the formula. The photosemiconductor element operates with a small operating voltage and large current as a bistable element when a load resistor 14 larger than the differential load resistor of the photosemiconductor element and a power supply 15 are connected in series to (p) side and (n) side electrodes 12, 13. The resistance 14 is thereby lowered and the time constant is decreased; in addition, light is confined in the quantum well barrier by the layers 2, 8, by which the operating speed is increased while the incident power is small.

Abstract: PURPOSE:To minimize a loss of an induction motor to occur at the time of low speed operation by a system wherein voltage waves of an AC power are thinned out by a given number by stages according to number of revolutions of an induction motor, and they are added to the induction motor. CONSTITUTION:Number of revolutions of an induction motor 5 is detected by a speed generator 6, and a switching circuit 9 to control power voltage waves through thinning out is added to a circuit to control automatically an AC switching element of thyristors 7, 8 through controlling a conducting phase control angle of a conduction controlling circuit 3 according to a deviation with an output of a speed setting circuit 1. Then, a switching circuit 9 controls the conduction controlling circuit 3 according to a section in which the number of revolutions corresponds to a set point in the switching circuit, and applies power voltage waves to the induction motor 5 through thinning out every other wave and then at every two waves from the full wave. Thus a small input power is acceptable as compared with a conventional system, thereby minimizing a loss to occur at the time of low speed operation.

Title: Method of forming slant side wall in integrated circuit
Inventor: FUU TAI RIYUU
IPC: H01L29/417
Filed: 1990-03-15
Abstract: PURPOSE: To attain the formation of an inclined side wall in a contact hole by forming an insulating layer on an integrated circuit, smoothing its surface through reflow and then performing etching. CONSTITUTION: A phosphorus-silicate glass or boron-phosphorus-silicate glass(BPSG) layer 36 is formed on the integrated circuit and afterwards, it surface is smoothed by reflowing. Next, the layer 36 is etched back while using anisotropic plasma etching, and a filling area 38 parallel with the sharp side wall of a side wall spacer 32 is formed. The area 38 has the comparatively smoothly inclined cross section because of the reflow of the BPSG layer 36 before etch back. Thus, the area 38 smoothes the profile of contact to steps on a source/drain area 34 and a mutual contact area 26 and the formation of voids or incomplete contacts are decreased.

Title: Thin film permanent magnet superior in rectangularity
Inventor: KITADA MASAHIRO
IPC: C22C19/07
Filed: 1984-04-05
Abstract: PURPOSE:To attempt to improve rectangularity at a magnetic hysteresis curve by adding a specified amount of Ni to Co-Pt series. CONSTITUTION:Assume a thin film magnet alloy of Co-Pt-Ni series which contains 10-30% Pt and 3-25% Ni by atomic percentage and a residual of which is composed of Co. When the content of Pt is out of this range, a coercive force of the thin film permanent magnet is reduced, which is not desirable. Also, when the content of Ni is less than 3%, it is difficult to improve rectangularity thereof. Even if a content of Ni exceeding 25% is added, the rectangularity is hardly improved and, on the contrary, the coercive force is largely reduced. As a result, characteristics as permanent magnets are lost.
