Title: Tuning system of electronic tuning car radio
Inventor: MIZUNO MASATAKA
IPC: H04B1/16
Filed: 1983-12-24
Abstract: PURPOSE:To facilitate receiving road-side information by depressing a service request button provided in a car radio of the system, where digital quantities for tuning are stored and channels are selected with push buttons, to receive roadside information. CONSTITUTION:Digital quantities corresponding to tuning frequencies are stored in the electronic car radio. When a desired button on a key matrix KMX connected to a control part CONT is depressed to select a channel, a local oscillator LO is controlled by a PLL so that a local oscillated frequency for one wave of FM or AM is generated. A button which selects 1,620kHz frequency for roadside traffic information service is added to channel selecting buttons. The broadcast which is received just before depression of this button is received again a prescribed time after depression of this button or by the operation of a return button. If this button is depressed continuously, the receiving frequency is switched to stand-by frequency 1,629kHz. In this case, the original broadcast is received after a prescribed time. Thus, road side traffic information repeated in a short time is received easily.

Filed: 1983-12-30
Abstract: PURPOSE:To obtain the high-performance hetero junction element with the improved mutual inductance by forming a P<-> layer by doping a small quantity of P type impurities in a GaAs layer. CONSTITUTION:A GaAs layer 22 in which the doped quantity of P type impurity is made 1X10<16>cm<-3> by molecular beam epitaxy method is grown on a semi-insulating GaAs substrate 21. After that, an A GaAs layer 23 is grown. Doping with P type impurity into the GaAs layer 22 is performed by adding Be during molecular beam epitaxy. At this time, the quantity of doped Be can be increased to about 10<17>cm<-3>. A metal to become a gate electrode 28 is attached to the above epitaxial layer and ions 31 are implanted to 2X10<13>cm<-3> by using this metallic electrode as a mask to form an impurity region 24.

Title: Control apparatus for motor
Inventor: HORIKAWA FUMIHIRO
IPC: G05B13/02
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To reduce a position error due to friction when a machine is reversed and to reduce a track error when a quadrant is changed over in a circular cutting operation in a numerically controlled apparatus. SOLUTION: A position error due to friction appears remarkably when a machine is reversed, i.e., a motor is reversed. A disturbance-torque observer 8 estimates a speed and a disturbance on the basis of the output of a detector 7. A motor-reversal detection part 10 judges the reversal of the motor. A variable gain part 9 weakens an estimated-disturbance compensation amount at a small gain in a steady state other than a definite time from the reversal of the motor on the basis of the output of the motor-reversal detection part 10. Thereby, a compensation corresponding to a sudden change in friction in the reversal of the machine can be compensated without generating a very small vibration, in a steady state, which is generated at a time when the disturbance-torque observer 8 is used by a high-band setting operation, and the position error can be reduced.

Title: Method for preventing banded structure of stainless steel plate
Inventor: YAMAGUCHI RYUJI
IPC: B22D11/10
Filed: 1994-09-14
Abstract: PURPOSE: To prevent the banded structure developed on the surface of a stainless steel plate after cold rolling - annealing by avoiding the developing cause itself and to clear the surface by using powder adjusted so that the viscosity and the solidified temp. of the powder used to a continuous caster satisfy the specific inequalities, respectively. CONSTITUTION: The banded structure developed on the surface of steel plate after cold rolling - annealing is caused by the unevenness of delta-ferrite quality and delta ferrite grain diameter due to ununiformity of cooling speed on the surface layer part of a cast slab cast in the continuous casting and in this result, the ununiformity to the growth of crystal grain on the surface layer part of steel plate is developed. In order to prevent this banded structure, the ununiformity of the cooling speed on the surface layer of cast slab is necessary to prevent. Then, the viscosity and the solidified temp. of the powder used in the continuous caster are adjusted so as to satisfy the inequality I and the inequality II. Wherein, η is the viscosity Poise at 1300 deg.C, T is solidified temp.  deg.C of the powder and V is casting speed m/min.

Abstract: PURPOSE:To generate accurate gate pulses freely from the variation of DC components in input signals and to reproduce data pulses stably by generating the gate pulses by an original waveform slicing system by adding or subtracting a DC component detected by a DC component detection circuit to a slice voltage or from the input signals. CONSTITUTION:This data pulse reproduction circuit is provided with a DC component detection circuit 8 which detects a DC component Vdc in input signals Si and a gate pulse generation circuit 9 which generates gate pulses Pg in an original waveform slicing system.
