Title: Semiconductor device
Inventor: EGUCHI KOUJI
IPC: H01L27/06
Filed: 1978-10-11
Abstract: PURPOSE:To provide a semiconductor device in which high resistance is obtained thereby to produce high density integration and easily control the resistance values by forming a resistance with polysilicon comprising an element which may produce an insulator by chemical combination with silicon. CONSTITUTION:In a zone formed as surrounded by field oxide films 12 in the surface of a silicon substrate 11 of one conductive type, for example, the p-type is formed a zone 13 into which impurities of the other conductive n<+>-type have been doped, and the surfaces of the film 12 and the zone 13 are covered with an oxide  film 14. Then an approximately 6,000Angstrom  polysilicon film 15 is grown through an opening provided in the oxide film 14, and nitrogen is implanted thereinto, for  example, in an amount of 1X10<17>cm<2> at 150keV. The resulting polysilicon film is  subjected to patterning to selectively form an aluminum wiring 17. Thus a high  resistance is available to the device with smaller dimensions. This polysilicon resistance can be formed simultaneously with silicon gate in MOSFET's, and applied to  a load transistor in static MOS memories.

IPC: C21C7/00
Filed: 1990-05-16
Abstract: PURPOSE:To execute correction of steel taping temp. with reserving heat quantity in a ladle and to suitably control the steel tapping temp. by applying the correction under consideration of lowering of the temp. with heat dissipation of ladle refractory, based on inner temp. of the ladle refractory and distance from the inner wall of ladle to temp. measuring point. CONSTITUTION:With a temp. sensor 2 embedded into the ladle refractory 1, the temp. in the ladle refractory 1 is measured. Further, by using a thickness meter 3, the distance L from inner wall 1A of the ladle to the temp. measuring point 2A of a temp. sensor 2 is measured or estimated. Based on this measured result, the reserving heat quantity in the ladle refractory 1 is estimated. The steel tapping temp. is corrected under consideration of the lowering of temp. with the heat dissipation of the ladle refractory 1 from this reserving heat quantity. By this method, the steel tapping temp. is controlled to the desired temp. range, and unevenness of the molten steel temp. at the time of arriving to continuous casting process is reduced.

Filed: 1990-05-16
Abstract: PURPOSE:To newly start frequency control at optional timing by reading out the frequency information of extracted candidates of the same language from a frequency information storing means and determining the output order of the candidates based upon the read result. CONSTITUTION:A certain reading is inputted through a keyboard (KB) 16 and 'KANA' (Japansese syllabary)/'KANJI' (Chinese character) conversion is specified by depressing a key. A CPU 10 extracts words corresponding to the inputted reading information from a dictionary stored in a dictionary area 15 in a ROM 12. The extracted words are set up in a homonym candidate table stored in a table area 34 of a RAM 11 as homonym candidates. Then, the CPU 10 refers flags stored in a flag area 33, and when a flag is set up, reads out updated/controlled freqency information from a frequency information area 32 and sets up the read information in the homonym candidate table. Thus, the CPU 10 sorts the homonym candidates in the order of frequency to determine the output order and a floppy disk device (FDD) 21 prints out document information. Thus, a document to be newly started can be inputted at optional timing.

Title: Magnetic recording device
Inventor: TAKIMOTO HIROYUKI
IPC: G11B5/02
Filed: 1985-06-12
Abstract: PURPOSE:To prevent the deterioration in a recording signal due to the effect of magnetic heads except a head to which a recording signal is applied by applying an output of a phase inverting circuit inverting the phase of the record ing signal to at least one head other than the magnetic head to which the record ing signal is applied. CONSTITUTION:A recording current is applied to La and Ra heads at a half period each while a drum is turned once. Danoting a recording current outputted from a recording amplifier ARa as IRa1 and a leakage current to a head Rb by the crosstalk from a rotary transformer to the current IRa1 as DELTAIRa2, then a current having the phase being the inversion of the phase of the current IRa1 and having a current DELTAIRa2, that is, -DELTAIRa2 is outputted from the amplifier ARb. As a result, the current due to the crosstalk is cancelled as DELTAIRa2+(-DELTAIRa2)=0 in the head Rb. Since a leakage current is generated in both the heads Lb and Tb in the recording by the head La, a current -3dILa2 is outputted from recording amplifiers ALb, ARb.

Filed: 1988-05-24
Abstract: PURPOSE:To impart speed/torque characteristic adapted for the utility of a motor by providing a rising torque setting signal setter, a torque rising change rate setting variable resistor, and a high seed setting signal setter. CONSTITUTION:A differential amplifier 1 supplies a differential voltage between the rotating speed of a motor M and a set voltage from a low speed setter 2 to the motor M through a comparator 4 with a maximum torque setter 4a and a power controller 5. When a load exceeds a set rising torque, a comparator 11a is operated to output the output voltage of the amplifier 1. Thus, a differential amplifier 12b amplifies the output voltage of a comparator 11b at an amplification factor set by a rising change rate setting variable resistor 12a. When a load torque is further increased to arrive at the high speed set speed, the output voltage from the comparator 13b becomes a constant value. When the load torque is further increased, the output voltage from the comparator 4 becomes constant.
