Title: Method and apparatus for etching silicon carbide
Inventor: KITAHATA MAKOTO
IPC: H01L21/3065
Filed: 1992-11-20
Abstract: PURPOSE:To facilitate removal of a silicon carbide on the surface of an Si substrate and to simplify a troublesome substrate cleaning by irradiating the surface of a silicon carbide with light having wavelengths in ultraviolet regions. CONSTITUTION:A silicon carbide 1 is installed on a substrate holding mechanism 3 installed in a vacuum container 2, and the surface of the silicon carbide 1 is irradiated with a light 6 having wavelengths in ultraviolet regions through an optical window 5 from a light source 4. The light 6 having wavelengths in ultraviolet regions is absorbed in an extreme surface of the silicon carbide 1 and heats a silicon carbide surface locally. Therefore, evaporation of silicon carbide occurs momentarily on the silicon carbide surface to etch it. This etching is preferable because of occurrence of no oxidation on an etched surface in an inactive gas such as Ar under a vacuum, and further because of being more efficient in a reactive gas atmosphere such as chlorine gas.

IPC: H03F3/45
Filed: 1991-11-27
Abstract: PURPOSE:To set a gain of a 2nd operational amplifier to a desired value even when a DC level of an output voltage of a 1st operational amplifier takes any level by making a potential at one input terminal of a 3rd operational amplifier coincident with a potential at an output terminal of the 3rd operational amplifier. CONSTITUTION:Resistors 2, 3 connecting to a 1st operational amplifier 1 correspond to a 1st resistor and resistors 10, 11 connecting to a 2nd operational amplifier 4 correspond to a 2nd resistor. A resistor 13 and a variable resistor 14 are connected in series between a power supply Vcc and ground thereby forming a variable resistor circuit. Furthermore, a 3rd operational amplifier 15 or the like is provided. Then the 3rd operational amplifier 15 acts like a buffer. Then a gain of a 2nd operational amplifier 4 is set to a desired value independently of a DC level of an output voltage of the 1st operational amplifier by adjusting a DC level of one input terminal of the 3rd operational amplifier 15 with the variable resistor circuit to improve the degree of freedom of the design.

Abstract: PROBLEM TO BE SOLVED: To prevent a parked vehicle from exiting without paying the regular charge by photographing an image including at least the license plate number of the parked vehicle and displaying the photographed image in a place where parking lot users can recognize it. SOLUTION: When a vehicle sensor 14 detects a vehicle 10 entering the parking lot, a photographing camera 22 is put in operation to take a picture of the entering vehicle 10 and the taken picture is displayed on a display 24 for displaying messages to parking lot users. The camera 22 takes a picture including at least the license plate number of the parked vehicle 10. Then the entrance information on the vehicle 10 is sent to a liquidation machine 16 and the charging is started. Once the charge is paid, the liquidation machine 16 sends a liquidation end signal to a controller 26, the image of the parked vehicle 10 displayed on the display 24 is cleared, and a message showing that a vehicle can exit is displayed.  If the sensor 14 does not detect the vehicle 10 any more although the vehicle is charged, the image of the vehicle 10 is held and the vehicle is specified as a vehicle 10 having exited without payment.

Title: Selective ejection system and method to maintain space priority order to be used in common memory asynchronous transfer mode switch
Inventor: ABIJITSUTO KUMAA CHIYAUDOHARII
IPC: H04L12/56
Filed: 1995-12-01
Abstract: PROBLEM TO BE SOLVED: To realize a system and method for queuing and selective extrusion to be used in a shared memory asynchronous mode(ATM) switch. SOLUTION: A shared memory stores a packet having one field and at most two pointers in a queue. In each queue, a packet having spatial priority order is stored in a sub-queue having corresponding priority order. Those packets are stored in the sub-queue with priority by using a first pointer indicating the next packet in the queue with the same spatial priority order. A second pointer related with the stored packet indicates the previous packet in an FIFO sequence in the queue with the equal or larger spatial priority order. The field of the packet is used for storing the value of the priority order corresponding to the next packet in the FIFO sequence in the queue, and this field is used for deciding the sub-sequence with priority to be processed next by a processor.

Title: Optical-fiber scanning-beam detctor
Inventor: FURANKU SHII JIENOBUEEZU
IPC: G02B6/24
Filed: 1995-12-01
Abstract: PROBLEM TO BE SOLVED: To detect a scanning beam traversing a detector by providing a light incident window at the input terminal of an optical fiber and introducing a light in the direction other than the axial direction of an optical fiber and then transmitting the light along the axial direction to a photodetector. SOLUTION: The end face 52 of an optical fiber 50 is inclined by 45 deg. and a side of the optical fiber 50 is made flat at a part which is the closest to the end face 52. A recessed flat window 54 is then made in the flat side and an inlet end is defined by the end face 52 and window 54. The optical fiber 50 is set such that a raster output scanner ROS 5 traverses the window 54. A light enters through the window 54 into the optical fiber 50 and then it is reflected totally on the end face 52 to advance along the axis of fiber. A luminous flux signal propagates along the overall length of optical fiber 50 while repeating total reflection and exits from an end 6A.  Since a flat window is employed in place of a curved optical fiber, wave front of beam is sustained and the geometry perpendicular to an arbitrary traversing direction, e.g. a passage, of ROS beam minimizing the optical loss is useful for avoiding a curve of large angle of fiber having small radius of curvature.

IPC: H04W88/02
Filed: 1996-11-26
Abstract: PROBLEM TO BE SOLVED: To improve the transmission efficiency and operability of a radio call system by making the system only transmit an answer message to a partner who is required to send the message. SOLUTION: The receiver of a selective radio call system has a telephone number retrieval section 107 which retrieves a preregistered telephone number based on the content of a message upon receiving the message and transmits an answer message to the subscriber of the retrieved number through radio telephone. The receiver is provided with an answer flag confirming section which confirms the necessity of an answer message from an answer flag, a received message segmenting section which returns part of a received message to the call subscriber by segmenting the part of the message, and a transmitting message preparing section which prepares its own message.  Therefore, the transmission efficiency and operability of the radio call system can be improved, because the sender of a message can distinguish the answer to the message and can only transmit an answer message to a partner who requires the answer message.
