Title: Obstacle detecting circuit for unmanned carrier vehicle
Inventor: WATANABE YUKINORI
IPC: G05D1/02
Filed: 1989-05-18
Abstract: PURPOSE:To shorten a distance between unmanned carrier vehicles and to improve space efficiency while securing high safety by providing an obstacle detecting circuit with a contactless obstacle sensor and a contact type contact detecting sensor and switching a traveling speed. CONSTITUTION:The obstacle detecting circuit is provided with the obstacle detecting sensor 1, an optical sensor 3, two soft bumpers 5, a light emitter 2, a driving motor 8, and a traveling control CPU 7. A driving system is controlled so that the unmanned carrier vehicle concerned does not approach the forward unmanned carrier vehicle more than a prescribed distance when its optical sensor does not detect light emitted from a light emitter 2 mounted on the forward vehicle. When the optical sensor 3 detects the light from the light emitter 2 on the preceding vehicle, the driving system is controlled so that the vehicle concerned approaches the preceding vehicle up to coming into contact with each other. If the succeeding unmanned carrier vehicle in traveling comes into contact with the rear of the forward traveling unmanned carrier vehicle when the light emitter 2 on the forward vehicle is lightened, the succeeding vehicle is stopped. Consequently, the distance between unmanned carrier vehicles is shortened while securing high safety and the space efficiency can be improved.

Title: Digital speed control circuit
Inventor: IZUME TAKATOMO
IPC: G05D13/62
Filed: 1979-09-27
Abstract: PURPOSE: Not only to enhance the control accuracy but also to reduce a loss time of the sampling time, by accumulating the enough extent of error required for the speed control accuracy in the circulating list.  
     CONSTITUTION: The central processing unit 10 writes the speed error ERR 0  in the LIST 0  address when the sampling clock is "0", writes the speed error ERR 1  in the LIST 1  when the clock is "1", and writes ERR m-1  in the LIST m-1  when the clock is "n-1" in due order. At the next clock of "n-1", the clock becomes "0" over again, and said operation is repeated. The capacity (number of address "n") of this circulating list decides "n" by assumptively putting "T" as the sampling time required for a speedy response so that n×T can be the sampling time required for obtaining accuracy of the speed control. The central processing unit 10 rewrites the contents of the list to the sampling clock, derives the sum total of ERR 0  through ERR n-1  of the list, and outputs it to the D/A converter 2.

Title: Electron-beam exposure apparatus
Inventor: YUASA TETSUO
IPC: H01L21/027
Filed: 1978-10-06
Abstract: PURPOSE: To sense the size of the rectangular cross section of a beam and the current density thereof exactly, by sensing only the portion of a beam adjacent to each side of the rectangular cross section of the beam.  
     CONSTITUTION: A screen plate 15 with a slit 16 is arranged above a piece of wire 10 so that the wire 10 is perpendicular with the edges of the slit 16a and 16b, and the direction of the edges are in coincidence with the direction of the movement of a beam spot S 1 (S 2 ). The spot S 1  is moved to the edge 16a so that only the shaded portion can be sensed by a sensor 11, and is traveled along the edge. When the output of the sensor 11 is differentiated twice, the pulse interval indicates the length of the upper side d 1  of the spot S. When the spot S 2  is moved to the upper side and moved along the edge 16b, the pulse interval indicates the length of the lower side d 2  of the spot. In this constitution, the difference between the opposing two sides of the cross section can be exactly sensed by the comparison of the pulse intervals, and the exact distribution can be obtained since the differential wave form changes into a saw-tooth shape and a secondary curve if the current density is uneven.

Title: Evaluation of semiconductor element
Inventor: UCHIDA MAKOTO
IPC: H01L21/66
Filed: 1979-09-25
Abstract: PURPOSE:To destroy an improper semiconductor element and to remove it by applying a reverse voltage having lower than rated value to the element immediately after flowing a forward pulse current to a p-n junction of the element. CONSTITUTION:When a sinusoidal current i of half cycle is flowed in a forward direction through the semiconductor element, currents i1-i3 flow therethrough in response to times t1-t3. Subsequently, an abrupt reverse voltage v is applied to the element. A junction J1 is reversely biased at this time to thereby cause a depletion layer to be extended, but junctions J2 and J3 of impurity-mixed regions 7 and 8 respectively are forwardly biased, a hole injection current 4 flows therethrough, and the junction J1 is avalanched in multiplication and is thus conducted. Since the regions 7 and 8 are however narrow in width, the currents are concentrated and are accordingly completely destroyed. Resultantly, the element can be evaluated, and the reliability of the residual element can be consequently improved.

IPC: H04Q3/42
Filed: 1983-07-08
Abstract: PURPOSE:To reduce the mounting area by providing a filter function to the feeding circuit in a polarity inverting pulse transmission circuit to eliminate the need for an externally mounted charging filter. CONSTITUTION:When a control signal of feeding circuit OFF is inputted to an input terminal 35, transistors (TRs) 31, 29, 30 are turned off, then TRs 27, 28 are turned off and a voltage feedback loop is opened. Since a capacitor C26 is charged gradually to a voltage of a power supply 5 through resistors 16, 17, the bias of TRs 18, 19 is reduced gradually to zero and a talking current flowing to output terminals 24, 25 is reduced gradually to zero. Thus, the feeding circuit has a filter characteristic, the noise appearing between terminals 24, 25 is very small. When a control signal of feeding circuit ON is inputted to the terminal 35, Trs 31-27 are turned on, a voltage feedback loop is formed and the TRs 18, 19 are biased. Since the voltage of the C26 attains gradually to a collector voltage of the TRs 18, 19 through resistors 12, 13, the talking current is increased gradually and the noise appearing at the terminals 24, 25 is made small.

Title: Adhesion processor for semiconductor manufacturing device
Inventor: MANABE TOYOO
IPC: G03F7/085
Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To uniformly apply a resist adhesion reinforcing agent to a wafer. SOLUTION: As a wafer 112 is rotated with a wafer stage 110 by a motor 10 even if the steam of Hexamethyl (HMDS) being a resist adhesion reinforcing agent jetting ports 14 and 16 is ununiform, HMDS is uniformly applied to the surface of the wafer. In addition, as the steam of HMDS is jetted through the ports 14 and 16, HMDS steam of higher uniform density is supplied to the surface of the wafer for effective uniformly application of HMDS to the surface of the wafer. Since pipes 18 and 20 for supplying HMDS steam to an adhesion chamber 4 are heated by nichrome wires 22, HMDS steam does not liquefy due to contact with the inner walls of the cold pipes 18 and 20, and HMDS is prevented from being jet-stuck to the surface of the wafer in the state of drops.
