Title: Stealth radar apparatus
Inventor: SUGIYAMA DAISUKE
IPC: G01S7/02
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To make a target unable to specify a place of a radar apparatus body by setting an antenna for directly transmitting radio waves to the target at a repeater and making the target specify only a position of the radio wave repeater. SOLUTION: When a radar transceiver 1 starts transmitting, a unidirectional antenna 7 irradiates a primary transmission wave 9. When the transmission wave 9 reaches a unidirectional antenna 8, a phased array antenna 2 emits a transmission wave 3. A transmission reception direction control device 6 changes a direction of the transmission wave 3. When the radar transceiver 1 detects a detection wave 5 reflected by a target 4, the direction control device 6 fixes a transmission reception direction to a direction of the target 4. The transceiver 1 obtains information on a position of the target from a reception wave 10 which is the wave 5 passing through a repeater T.  A processor 12 sends to the transceiver 1 a correction command for the position of the target 4 on the basis of a position of the transceiver 1 stored in a memory device 11 and a relative position of the antenna 2, whereby a relative position of the transceiver 1 and the target 4 is obtained.

Title: File update history acquisition system
Inventor: HIRANO SHIGEKI
IPC: G06F12/00
Filed: 1990-03-30
Abstract: PURPOSE:To shorten the processing time by performing the output processing of a file update history in parallel with the processing of a data file update main body. CONSTITUTION:When a file processing main body 3 issues a data read request A1, an extended file input/output means 1 takes over contents of the data read request A1 to issue a data read request A2. Read data 8 is preserved in a memory buffer 7 by the extended file input/output means 1, and the file processing main body 3 issues an update report A3 when data 8 on the buffer 7 is updated. When receiving the update report A3, the extended file input/output means 1 issues a file update history acquisition indication A4, and a file update history acquiring means 2 writes the update history of data 8 of the buffer 7 in an update history file 6. At this time, the extended file input/output means 1 can perform the operation in parallel with the file update history acquiring means 2. Thus, the processing time is shortened.

Abstract: PURPOSE:To ensure that printing fault resulting from the loading of non- specified paper is prevented by storing the value of a comparative voltage to a designated paper in memory beforehand on the CPU and detecting the paper based on the comparative voltage. CONSTITUTION:If a comparative voltage is set based on a specified paper, a specified paper 8 is arranged between the LED 7 of a photosensor 6 and a phototransistor 9, and light is emitted to the paper 8 from the LED 7 by operating the photosensor 6. Then the light passing through the paper 8 is received by the phototransistor 9, and the detected voltage which changes depending on the intensity of light is output to a comparator. In the meantime, a logically combined signal is changed and output to a digital/analog converter 10, and this digital signal is converted to an analog voltage. This analog voltage is output to the comparator 2 as a comparative voltage. If the signal which is output to CPU 1 is 1, the CPU interprets that a specified paper 8 is loaded, and if the signal which is output from the comparator is 0, the CPU interprets that the specified paper 8 is not loaded.

IPC: F04D29/54
Filed: 1982-05-21
Abstract: PURPOSE:To prevent stall of vane and spread the stable operation range during low speed revolution by forming a preparatory air chamber and a swirl flow generating ring on the wall surface of an upstream casing and forming a bleeding chamber and a bleeding hole on the wall surface of a downstream casing and communicating the preparatory air chamber to the bleeding chamber through a communication pipe and a bleeding valve. CONSTITUTION:A preparatory air chamber 18 and a swirl flow generating ring 19 are installed on the wall surface of an upstream casing of the first stage movable vane 17, and a bleeding chamber 15 and a bleeding hole 16 are formed on the wall surface of a downstream casing, and the preparatory air chamber 18 and the bleeding chamber 15 are communicated to each other through a communication pipe 21 and a bleeding valve 22. When the bleeding valve 22 is opened during low speed revolution, bleeding stream in the downstream course flows through the swirl flow generating ring 19. Since, in this case, a swirl hole 20 is tilted, swirl is provided for the stream at the inlet port of the first-stage movable vane 17. Further, as the bleeding stream is not released and returns to the inlet port side, only a half amount of bleed required in the conventional method may be enough in this invention. Further, a relative inflow angle equal to the target of design can be achieved, in low speed revolution, and stall of vane can be avoided, while the stable operation range can be extended.

IPC: G06T7/20
Filed: 1997-04-03
Abstract: PROBLEM TO BE SOLVED: To surely extract a true moving target without losing it in a background picture at the time of capturing the moving target by an image pickup equipment loaded on a guiding missile or the like. SOLUTION: A spatial area including a moving target 2 is image picked up by an image pickup equipment, and two time-sequential screens are supplied to a luminance detector. The luminance detector divides each image picked screen into plural areas, and detects average luminance in each area. An identifying circuit which obtains the average luminance in each area correspondingly compares the average luminance in each area on the time sequence, and identifies the moving target included in a background picture by using a difference between the moving vector of the background area and the moving vector of an area including the moving target. Thus, the moving target is identified by dividing the area and based on a picture featured value such as the gradation difference of luminance so that quick and highly precise detection can be attained.
