Filed: 1994-07-15
Abstract: PURPOSE:To surely discriminate the travelling direction of the object by using the conventional sensor by discriminating the travelling direction of the object by combining an ON, OFF signal and a telemetric signal of plural distance detection sensors. CONSTITUTION:A device 2 for issuing a parking ticket has ultrasonic sensors S1-S3 as three distance detection sensors with the center opening degree theta1 to theta3 (for example, 50 deg., 90 deg., and 126 deg.) in the detection direction when the regular travelling direction of a car A is taken as zero. A gate device 4 has ultrasonic sensors S4 and S5 as two distance detection sensors with the center angles theta4 and theta5 (for example, 40 deg. and 115 deg.) in the detection direction when the regular travelling distance of the car A is taken as zero. In short, five ultrasonic sensors S1-S5 are set radially. Based on the combination of the ON/OFF signal and the telemetric signal from the distance detection sensors S1-S5, the travelling direction of the vehicle A is discriminated.

Title: Heat-treating method and heat-treating equipment
Inventor: SHIBAHARA KENTARO
IPC: H01L21/22
Filed: 1989-07-18
Abstract: PURPOSE:To uniformize temperature distribution by performing heat treatment while making atmospheric gas flow vertically from the lower part toward the upper part. CONSTITUTION:Atmospheric gas is made to flow upwards from below in the direction from a gas introducing part 40 to a gas discharging part 41. The gas introducing part 40 is installed at the central part of the lower end of a furnace core tube 5. The gas discharging part 41 is installed on the side surface of the upper end thereof. A wafer 2 is fixed on a susceptor 3 by using a fixing jig 20, and retained vertically to the introduced gas flow by a retaining rod 4. When a current is applied to a high frequency work coil 1, the temperature of the susceptor rises, and the wafer 2 is heated. The gas heated in the vicinity of the center of the wafer 2 flows horizontally along the wafer 2, and flows upwards from the end-portion of the wafer 2, so that convection and turbulence do not generate. Since the gas heated at the central part of the wafer 2 passes the peripheral part, the temperature of the peripheral part becomes high. However, by arranging notches on the periphery of the heating susceptor 3, induction current on the peripheral part is reduced, so that the quantity of generating heat is decreased and the temperature is uniformized. Thereby heat-treating method and heat treating equipment excellent in uniformity of heat treatment temperature and reproducibility can be obtained, and yield and reliability can be improved.

CONSTITUTION:A value of an instruction Ir of the current to be made to flow into a 3-phase synchronous motor 8 of each constant period is received. Next, a combined current IS of an inverter circuit 7 to which a total sum of currents flowing into each phase is detected by a current detector 1, this value is digitized by an A/D converter 2 and then it is converted to a feedback current value If. Next, deviation Id between current instruction Ir to be made to flow into the motor armature and feedback current value If is obtained by an adder 3. Next, the compensating calculation such as PI control etc., is conducted with a compensating 4 to the deviation Id and the PWM width Cu, Cv, Cw, of each phase are obtained by the PWM circuit 6 from the result of calculation. Simultaneously, a switching pattern of the inverter circuit 7 is determined from the commutation signal CS detected by the commutation sensor 5.
