Title: Preparation of polyimide powder
Inventor: IGARASHI KAZUMASA
IPC: C08G73/10
Filed: 1981-05-18
Abstract: PURPOSE: To prepare the titled powder with simple preparation process, by forming an imidated film on the surface of a solution of a polyimide precursor to  seal the solution, heating the solution to effect the imidation reaction, and precipitating the product in powdery form by the action of the by-producted low- molecular compound.  
     CONSTITUTION: An imidated film (preferably 20W50μ in thickness) is formed on the liquid surface of a solution of a polyimide precursor (a polyamic acid solution) by blasting hot air of usually 150W200°C for about 1W3hr. The polyamide precursor solution shielded with the film is heat-treated usually at 200W300°C for 12W24hr to effect the imidation reaction and at the same time to make the produced imidated compound hardly soluble by keeping the by-produced low-molecular compound in the solution shielded with the film. The objective polyimide powder can be obtained as precipitate. The polyamic acid solution is preferably the one obtained by condensing a tetracarboxylic acid dianhydride of formulaI (e.g. pyromellitic dianhydride) and a diamine of formula II (e.g. p-phenylenediamine) in an organic solvent.

Title: Alloy coupling indium bumd and its treatment meihod
Inventor: RONARUDO ERU UIRIAMUSU
IPC: H01L23/485
Filed: 1990-03-23
Abstract: PURPOSE: To strongly combine a bump to a pad by pressing an indium bump to a gold bond pad for a short time for temporary fusion for press-contact and then perfectly alloying the indium bump with the gold bond pad. CONSTITUTION: An indium bump 11 is alloy-bonded with a gold pad 20 by pressing for about 10 seconds at a pressure about 800 pounds per 1 square inch. The pressure temporarily fuses two components, and the fused indium bump 11 and gold pad 20 are heated at about 100 deg.C for about one hour. By this heating, gold is diffused in indium for forming diffusion-welding. Thus, alloyed bond of high strength is provided.

Title: Semiconductor control rectifier
Inventor: MURAKAMI SUSUMU
IPC: H01L29/74
Filed: 1982-05-07
Abstract: PURPOSE:To obtain the titled rectifier having high injection efficiency of electrons from an N type emitter at a part of a P type base layer, having a low gate trigger current, a low ON- voltage of the others, and moreover having a large di/dt withstand strength and also having a large dv/dt withstand strength by a method wherein the part mentioned above at which part the maximum value of impurity concentration and thickness are small is provided in the P type layer directly under the N type emitter. CONSTITUTION:Both the one-side conductive emitter layer 3 and another-side conductive base layer 4 are exposed on the main surface on one side of a semiconductor substrate as to surround the emitter layer with the base layer, and the maximum value of impurity concentration and thickness of the base layer corresponding to the projected regions 41, 42 of the layer 3 to the main surface on another side of the semiconductor substrate are made smaller than the other parts. The maximum value of impurity concentration is smaller at the region 41 than at the regions 42. In the forward directionally obstructed condition, because depletion layers extended from the regions 42 under the layer 3 extend up to the lower parts of the region 41 of the P type base layer 4, an anode voltage applied in the forward direction is obstructed even by the thin part at the region 41, and formation in high withstand voltage structure is not damaged. Because the device contains the P type base region 41 having favorable injection efficiency of electrons from the layer 3, the gate trigger current of the P- N-P-N four layer active region becomes to have the extremely small value, and the di/dt withstand strength is enlarged.

Title: Induction motor control system
Inventor: KADOKURA TOSHIO
IPC: H02P3/24
Filed: 1978-06-22
Abstract: PURPOSE: To reduce the heat and noise of an induction motor by always energizing two serial thyristors in ON state as connected in parallel with the motor as its load to thereby provide a circulating diode therefor.  
     CONSTITUTION: When a contactor 13 is opened and a contactor 14 is closed at DC dynamic braking time, a phase controller 5 applies control pulse signals 5a, 5b to thyristors SCR3, SCR4, respectively. Simultaneously, an arc pulse signal generator 6 applies an arc pulse 6a to thyristors SCR1, SCR2. Accordingly, reverse voltage is applied to the thyristors SCR3, SCR4. When the thyristors SCR3, SCR4 are deenergized, the thyristors SCR1, SCR2 are conducted to cause electromagnetic energy of primary winding inductance to flow through the primary winding of an induction motor 3 through the thyristors SCR1, SCR2. Thus, the current becomes continuous waveform with less ripple rate.
