Title: Manufacture of reactive power compensator
Inventor: KONISHI SHIGEO
IPC: H02J3/18
Filed: 1990-05-11
Abstract: PURPOSE:To calculate a compensating current command value by calculating the unfluctuated component of a current value in effective power or an effective power component as an uncompensated object, converting this component to an instantaneous three-phase current value and subtracting it from an original load current value. CONSTITUTION:In a compensating current calculation circuit 3A, multipliers 8a and 8b and an adder/subtracter 9a calculate effective power P from two- phase currents ialpha and ibeta, which are obtained by three-phase/two-phase conversion circuits 7a and 7b, and two-phase voltages ealpha and ebeta, and the unfluctuated component (average) P of the power P is taken out by a low-pass filter. Multipliers 8e and 8f, adder/subtractor 9c and dividers 11a and 11b converts the voltages ealpha and ebeta to ealpha/(ealpha<2>+ealpha<2>) and ebeta/(ebeta<2>+ebeta<2>) and multipliers 8g and 8i converts the component (average) P to two-phase currents iualpha and iubeta as the uncompensated component. A two-phase/three-phase conversion circuit 12 converts the currents iualpha and iubeta to instantaneous three-phase current values iua, iub and iuc as the uncompensated components and these values are subtracted from loading currents ia, ib and ic so as to calculate compensating current com mand values ica*, icb* and icc*.

Title: Production of semiconductor device
Inventor: OGIUE KATSUMI
IPC: H01L21/22
Filed: 1977-10-14
Abstract: PURPOSE: To produce a device of small element sizes by forming the opposite conductivity type layer formed on substrate front to island form by etching grooves and performing enlarged diffusion.  
     CONSTITUTION: After an N +  layer 2 and an oxide film 3 are made on P type Si, etching grooves 5 are provided through a nitride film mask 4, isolating the N +  layer 2 in island form. P +  ion implanted layers 6 are created only in the groove bottom by making use of the eaves 4' of the the mask, after which annealing is performed. When the films 4, 3 are removed and an N layer 8 is made, the N +  layer 2 and P +  layer 6 diffuse in the layer 8. Next, masks 13 by oxide film 11 and nitride film 12 are selectively formed, after which an oxide film 14 is made. The film 14 is selectively opened and N +  layers 16 are made down to the layer 2. Next, B ions are implanted to create a P layer 17 through self-alignment. After annealing in N 2 , the surface is covered with PSG 18 and further a phosphorus doped viscous glass film 19 is spin-coated to flatten the grooves. Next, the films 19, 18, 14 are opened, an N +  layer 20 is provided and electrode windows 20, 23 are selectively formed, to which electrodes are attached. Since this method eliminates the need for mask margins and does not produce any bird heads, the scale of integration may be increased

Title: Semiconductor pressure gauge
Inventor: KUWAYAMA HIDEKI
IPC: G01L9/04
Filed: 1993-05-25
Abstract: PURPOSE:To absorb the generated distortion due to temperature change and better the temperature characteristic by providing a semiconductor chip with a recessed part where a diaphragm is provided as a distortion generator and a semiconductor pressure element installed in the recessed part. CONSTITUTION:When a reference pressure Ps is transmitted in a pressure introduction room 22 and a measuring pressure Pm is added from outside to a diaphragm 3, the diaphragm 3 displaces due to the pressure difference between the measuring pressure Pm and the reference pressure Ps. This displacement is electrically detected with a semiconductor detection element 4, and electric signal output corresponding to the measuring pressure Pm is obtained. Distortion is generated at the connection part of a chip base plate 21 and a support body 24 due to temperature change. However, a stiff small ring-shaped insulation part is formed by a ring groove 27 provided on both sides of the base plate 21 and therefore, the distortion is absorbed in this ring-shaped insulation part, so that the distortion transmitted to the diaphragm 3 can be drastically reduced.

Abstract: PURPOSE: To obtain a cheap hammer driving circuit operation check system by performing the test drive of hammers successively with a pulse width, by which hammers are not operated, during a period other than the printing time by a hammer driving circuit.  
     CONSTITUTION: Echo check is executed during a period such as a line feed time other than the printing time. First, shift register 200 is reset by signal 104. Next, signal 106 is inputted to set the output of the first bit of shift register 200 to a high level by shift pulse 105. Further, pulse 103 is inputted, and one-shot 220 of the first digit is triggerred to drive hammer driver 230. As a result, echo 241 is outputted from echo detection circuit 240, and output 131 of an echo amplifier is broken. If echo is outputted normally, output 131 of echo amplifier 130 becomes low-level, and echo error 141 is not outputted when pulse 101 is applied. Next, signal 105 is inputted to transfer the control to check for the second bit.

Abstract: PURPOSE: To reduce the cement burning calory by eliminating only air from a mixed flow of air and pulverized coal directly before an attached combustion supporting furnace to form a high concentration pulverized coal stream and suppressing the reduction of a high temperature air quantity from a cooler for cooling blown clinker.  
     CONSTITUTION: In a cement burning device provided with a suspension perheater, high temperature air recovered from a cooler 3 cooling high temperature clinker discharged from a kiln 1, reaches an auxiliary combustion furnace 5 via a duct 6 to perform combustion. In the intermediate parts of a pressure feed pipe 14 and a high concentration pressure feed pipe 15 from a coal drying and cracking device 11 to the combustion supporting furnace 5, a cyclone 16 and a back filter 17 are provided, and the gaseous mixture flowing from the pressure feed pipe 14 to the cyclone 16 is divided into air and pulverized coal and the majority part of air is filtered by a filter 17 and discharged into the atmosphere. On the other hand, a part of air reaches a burner 7 of the auxiliary combustion furnace 5 from the lower part of the cyclone 16 together with separated pulverized coal as a high concentration gaseous mixture. Since the cyclone, and the filter 17 are installed in the proximity of the auxilisry combustion furnace 5, the pressure feed pipe 5 is short and the pipeline resistance is small. Therefore, it is possible to reduce the pressure of the blower 12.

IPC: G05B9/03
Filed: 1983-07-07
Abstract: PURPOSE:To improve the reliability of a multiplex structure controller by identifying the normal or abnormal state of a controller as well as a route reaching an output switch from the controller. CONSTITUTION:The diagnosis parts 141A and 141B of output signal diagnosis boards 14A and 14B collate the supplied control signals CA and CB with each other for every fixed period T0 and then delivers a switch command to deliver the signal CA or CB of a system A or B which is previously decided if the coincidence is obtained from said collation. When no coincidence is obtained between both control signals, each control signal of the preceding collation is compared with the present control signal to select the signal CB, for example, which has a smaller degree of variation. Based on this selection, a switch command is delivered to relay drivers 145- and 146- from a diagnosis part 141-. Thus relays 131-134 and 135-138 are turned off and on respectively at a time point t3. Then the signal CB is delivered. While the discordance signal is sent to controller diagnosis boards 12A and 12B as soon as the discordance is detected from said collation. Thus the question-answer diagnosis is given to controllers 1A and 1B, and at the same time a re-execution command is delivered (t5).

IPC: G01F23/00
Filed: 1986-05-30
Abstract: PURPOSE:To obtain accurate consumption quantity, by directly detecting the consumption state of liquefied petroleum gas due to the lowering in the liquid level of said gas by a liquid level sensor. CONSTITUTION:If the liquid level of a liquefied petroleum gas container is lowered, a float 16 falls along a guide rod 14 corresponding to the liquid level and, if falls to the lowest part, a magnet 24 is positioned at the outer periphery of a reed relay 20 to close the contact thereof. Then, a detection signal is supplied to an alarm part. Because the lowering of the liquid level is directly detected as compared with the detection of gas consumption due to the lowering in pressure, there is no possibility of generating an erroneous signal and consumption information consistent with the actual consumption quantity in the container is obtained.
