Abstract: PURPOSE:To obtain single crystal silicon layers separated by a thick insulation layer of SiO2 or Si3N4, by repeating the operations of implanting oxygen or nitrogen ions and of making silicon crystals grow thereon. CONSTITUTION:A dose of 10<17>/cm<2> of oxygen is implanted into a single crystal silicon substrate 3 by an acceleration energy of 150keV. Thereby a layer 5 with implanted oxygen, having a range Rp of about 5,000Angstrom  and DELTARp of + or -1,000Angstrom , is formed. The distribution of oxygen density in silicon crystals is of a Gaussian distribution type. Accordingly, a silicon surface region 6 is maintained in the state of single crystal. Next, this crystal substrate is heated to 800 deg.C, and a silicon single crystal of 72,000Angstrom  is made to grow thereon by an MBE method. By this heating on the occasion of the growth of the crystal, the layer with implanted oxygen is transformed into an SiO2 layer. By repeating the above operation ten times, a thick SiO2 layer 8 of about 2mum is formed. Lastly, a silicon layer 9 of 5,000Angstrom  is made to grow, and thereby a starting crystal for preparation of an element is prepared.

Title: Intermittent reception control system in mobile station
Inventor: KOBAYASHI KATSUMI
IPC: H04W72/04
Filed: 1983-09-01
Abstract: PURPOSE:To reduce power consumption by correcting a timing shift while keeping intermittent reception operation. CONSTITUTION:An oblique line frame to be received intermittently by a mobile station appears at each 2 frames and the first pulse of a power on/off pulse is named as a pulse 1, and the next pulses are named sequentially as pulses 2 and 3. An intermittent reception control section turns on a reception section power supply for a prescribed time T1 after the frame synchronism detection so that a specific frame is received and repeats it at a prescribed interval corresponding to 2 frames. When the frame synchronism detection, however, is not obtained during the time window T1, the time width of the next time window T2 is increased more than the T1. Since the shift of timing is corrected while keeping the intermittent receiving operation in this way, it is not required to turn on the power supply at all times, thereby saving power.

Title: Rotation malfunction detecting circuit for dc motor
Inventor: HATAGAMI TOSHIBUMI
IPC: H02P6/08
Filed: 1982-09-13
Abstract: PURPOSE:To detect the rotating malfunction of a brushless motor in a short time by detecting whether the detected output of rise and fall of the output of a plurality of Hall elements for detecting the position of a rotor is outputted or not without the prescribed period of time after starting. CONSTITUTION:When a starting is not normal and the rotation starting time of a rotor is delayed, the variation points of the outputs XH1-XH3 from Hall elements H1-H3 are displaced as broken lines. Thus, since the outputs of oneshot multivibrators MS1, MS2 do not present within the time (t), the output P2 of an NAND gate NAND temporarily falls as shown by a broken line. In this manner, the output P3 from a delay flip-flop FF becomes ''1'', and outputted as an alarm. The time (t) is determined by the torque of the motor, the maximum frictional coefficient of a magnetic head, the maximum viscosity of bearings and the maximum load.

Title: Arithmetic unit
Inventor: ICHIMURA YUTAKA
IPC: G06F7/494
Filed: 1990-06-18
Abstract: PURPOSE:To increase the computing speed by carrying out the decimal carry at addition of the decimal data with only a carry signal received from a 4-bit arithmetic and logic unit and corresponding to a hexadecimal number. CONSTITUTION:A +6 adder circuit ADD 1 and a +10 adder circuit ADD 2 are connected to each 4-bit arithmetic and logic unit ALU 1. When the decimal addition is carried out, each digit of an operand and a computed number is corrected so that the sum of these digits is excessive by 6. Then this sum is inputted to the corresponding ALU 1. When these input data are added together by each ALU 1, the result of addition carried out by the ALU 1 is outputted as it is at the digit where a carry signal is produced. Meanwhile the result of addition of the ALU 1 is outputted with -6 at the digit where no carry signal is produced. Thus the decimal carry is attained with only a carry signal received from the ALU 1 and corresponding to a hexadecimal number. Then the computing speed is increased.
