Title: Controlling method for dust feeder
Inventor: MORISHIMA MAKOTO
IPC: F23G5/50
Filed: 1993-12-13
Abstract: PURPOSE:To automatically and continuously completely burn refuse by increasing or decreasing a supply amount of either the refuse or combustion air based on signals from a luminance sensor and an O2 concentration sensor. CONSTITUTION:A burning state in a burning furnace is evaluated based on signals from a plurality of luminance sensors arranged at an interval above and below the furnace and an O2 concentration sensor 3 provided at an outlet of the furnace. Either a supply amount of refuse to an incinerator by a dust feeder 2 or a combustion air supply amount is increased or decreased based on signals from a luminance sensor 7 for an abrupt change of the burning state, and either the supply amount of the refuse to the incinerator by the feeder 2 or the combustion air supply amount is increased or decreased based on a signal from the sensor 3 for a relatively smooth change of the burning state. Thus, the burning state in the furnace can be always held in a state that complete burning is performed.

Title: Pattern generating device
Inventor: ONISHI FUJIO
IPC: G01R31/3183
Filed: 1987-12-11
Abstract: PURPOSE:To inspect all patterns by providing a 1st storage means for storing a previous pattern temporarily, a 2nd storage means for storing the expected value of an arithmetic result, and a 3rd storage means for storing a noncoincidence signal outputted by a comparing means. CONSTITUTION:A pattern '0' which is generated 1 is inputted to a register (RE) 2 with a 1st clock. The output value '0' of the RE 2 is inputted to a RE 3 with a 2nd clock and the RE 2 inputs a next pattern '1'. Then, an arithmetical logical operation circuit 4 subtracts the output value of the RE 3 from that of the RE 2 and outputs the result '1' to a comparing circuit 6. This circuit 6 decides that the output value '1' coincides with the output '1' of a register 5. Therefore, a FF 7 is in a '0' state. Further, the RE 3 inputs the output '2' of the RE 2 with a 3rd clock and the RE 2 takes in a pattern '0'. Consequently, the circuit 4 subtracts the output value of the RE 3 from that of the RE 2 and outputs the result '-1' to the circuit 6. This output value '-1' is compared with the output value '1' of a RE 5 to perform a decision 6 on their noncoincidence.

Filed: 1987-12-11
Abstract: PURPOSE:To make it possible to perform an image observation properly constantly so as to improve operability by controlling the gain of an amplifier for amplifying a Z-axis output by scan signals of X-axis or Y-axis. CONSTITUTION:Scan of a predetermined range is performed by scan signals of X-axis and Y-axis. At this time, a tunnel current output (Z-axis output) is amplified by an amplifier 7. Since this output is an index function of the distance between a probe 4 and a sample 5, an output proportionate to the distance can be obtained by amplifying by means of a logarithmic amplifier 8. This output is added to an error amplifier 9 to detect difference from a reference value, and this differential output is added to a Z-axis drive circuit 6 for controlling so that a Z-axis is constant. The Z-axis drive circuit output this time is indicated in a display 11 through an amplifier 10 to obtain an irregularity image in a sample surface.

Title: Driver for stepping motor
Inventor: OKAWA YOSHIHISA
IPC: H02P8/12
Filed: 1991-10-31
Abstract: PURPOSE:To increase a range of a stepping speed to stably seek a magnetic head without noise in a floppy disk unit. CONSTITUTION:A pulse interval of a pulse signal of an input stepping pulse is measured by a variable delay circuit 1, and the stepping pulse is delayed by a time corresponding to the interval. This delay signal S1 and the stepping signal are combined by an OR circuit 4, and a driving voltage corresponding to a combined signal S4 is generated by a controller 6 and a driving circuit 7. If the interval is increased, an exciting voltage selector 5 lowers an exciting voltage level as compared with a normal level. Accordingly, a stepping pulse having a delay time corresponding to the interval of the steeping pulse is generated. The delay pulse and the stepping pulse are combined thereby to stabilize a rotary drive. The driving voltage is lowered at a low speed thereby to reduce noise and current consumption at the time of low speed seeking.

Abstract: PURPOSE:To form a link base layer which has a concentration higher than an intrinsic base layer and sufficiently overelaps with the intrinsic base layer and a base contact layer, by forming the link base layer by diffusing impurities from a polysilicon base electrode. CONSTITUTION:A P-type base contact layer 10 is formed in an outer base region just under a polysilicon base leading-out electrode 5 formed on a P-type silicon substrate 1, and a P-type intrinsic base layer 11 is formed in an intrinsic base region under a polysilicon emitter electrode 8. A P-type link base layer 13 is formed so as to overlap with both the layer 11 and the layer 10 and connect both layers, by introducing P-type impurities in the electrode 5 into an outer base region. Hence the layer 13 can be formed in a self alignment manner with an emitter leading-out part, so that the layer 13 whose concentration is lower than the layer 10 and higher than the layer 11 is formed between the layers 10 and 11 in a self alignment manner with the layer 11 and an N-type emitter layer 12.
