Title: Aircraft position detector
Inventor: SAMEDA YOSHITOMI
IPC: G01V8/20
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To effectively detect the position of an aircraft even at the time of dense fog or severe snowfall and to eliminate the fault of service by providing a geomagnetic sensor embedded in the ground near the ground surface of a taxiway or apron as sensing means. SOLUTION: The lines of magnetic force of geomagnetism are parallel when there is no magnetic element, but are attracted to the element when there is the element such as an aircraft or a vehicle, and hence the magnetic flux density of the part is increased. Accordingly, when a geomagnetic sensor 51 is provided at a taxiway 2 to measure the magnetic field intensity near the ground surface, when an aircraft or the like is approached, the magnetic field is largely changed, and hence the presence of the aircraft can be detected. A position detector 52 detects the change of such distributed state according to the signal from the sensor 51, and submits the presence of the aircraft 1 when the change level exceeds a predetermined threshold value.  IF the sensor 51 capable of measuring magnetic field changes of three axis directions is adopted, the position of the aircraft can be more accurately detected.

Title: Measurement of mode field diameter of core enlarged optical fiber
Inventor: KIHARA MITSURU
IPC: G01M11/00
Filed: 1992-05-12
Abstract: PURPOSE:To non-destructively measure a mode field diameter(MFD) in used wavelength of a core enlarged optical fiber by measuring transmission loss in other wavelength which is more sensitive to transmission loss change due to heating than the used wavelength of a heated optical fiber. CONSTITUTION:Heating time of a TEC fiber is changed and change in MFD in communication use wavelength of 1.3mum. 1.0mum is used as a second wavelength example, so that relation between heating time and transmission loss change at this wavelength is obtained to calculate relation between transmission loss change at a wavelength of 1.0mum and MFD at 1.3mum from relation between heating time and MFD at 1.03mum and relation between heating time and transmission loss change at wavelength of 1.0mum. Transmission loss at wavelength 1.03mum hardly changes as MFD largely changes, while transmission loss also largely varies as MFD changes at 1.03 p m, thereby obtaining high sensitivity. Therefore by measuring transmission loss change at wavelength of 1.0mum, MFD at 1.03mum which is used wavelength can be obtained accurately.

Title: Shuttle device for sewing machine
Inventor: ASANO TAKESHI
IPC: B06B1/06
Filed: 1995-05-18
Abstract: PURPOSE: To provide the simply-constituted shuttle device of a sewing machine capable of improving the thread tightness of a sewing object, substantially reducing noise and omitting a conventional shuttle body fixing means. CONSTITUTION: A stopper 74 is engaged with a projection part 60 at the outer peripheral edge part of a shuttle body and obstructs the shuttle body 1 from being rotated together in the same direction accompanying the rotation of a rotating hook 2. Then, the stopper 74 is controlled so as to vibrate at a high frequency by a piezoelectric element 76 and thus, a friction coefficient becomes extremely small at the contact part of the projection part 60 of the shuttle body 1 and the stopper 74 compared to a case where high frequency drive is not performed. Thus, the loop of needle thread can be easily passed through the contact part of the projection part 60 of the shuttle body 1 and the stopper 74 while hardly being accompanied by thread tension.

Filed: 1983-06-30
Abstract: PURPOSE:To prevent a net and a fishing line under water from tangling around a propeller shaft or the like, by causing the operation of a clutch to be suitably interlocked to the braking of rotation of the propeller shaft. CONSTITUTION:A control lever 49 is connected by boarding wires 51, 52 to a cam 47 and a shift lever 55 in a reversing speed changer 53. When the control lever 49 is placed in a forward position F or a reverse position R, the shift lever 55 is controlled to be placed respectively in a forward position (f) or a reverse position (r) simultaneously advancing or reversing a ship because a brake shoe 35 is not forced to come into contact by pressure with a propeller shaft 19. While the control lever 49, when it is placed in a neutral position N, both controls the shift lever 55 to be placed in a neutral position (n) and presses a link mechanism 37 by the cam 47, causing the brake shoe 35 to forcibly come into contact by pressure with the propeller shaft 19. As a result, the ship is stopped while the propeller shaft 19 also stops its rotation.

Title: Differential pressure forming method
Inventor: KO TAKESHI
IPC: B22D21/04
Filed: 1995-05-18
Abstract: PURPOSE: To provide a differential pressure forming method which is difficult to develop internal defect in the whole body and can form a product having small crystal grain diameter. CONSTITUTION: While making the pressure in a second chamber R2 higher than the pressure in a first chamber R1 , the pressure in the first chamber R1 is made to higher than the atmospheric pressure, molten Mg is poured into a cavity 13a against the gravitation. Since the whole molten Mg filled up in the cavity 13a can be pressed at the equal pressure, even if the Mg cast product has a complicate shape, the internal defect is difficult to remain. Further, since the molten Mg filled up in the cavity 13a can be pressed at the higher pressure than the atmospheric pressure, the crystal growth is restrained and the structure having small grain diameter is obtd.

Title: Distance measuring apparatus
Inventor: ENDOU MASASHI
IPC: G01S7/486
Filed: 1980-08-28
Abstract: PURPOSE:To prevent the variation of the distance measuring accuracy through the feed back control of the amount of light emitted from a light emitting means to always make the amount of light received by a light receiving means constant. CONSTITUTION:Pulse modulated light emitted from a light emission element 1 and reflected on a measuring objective 4 is received by a semiconductor position detector 5 at the light receiving point x in the light receiving surface 5a. The detector 5 provides position signals in the form of signals currents IA and IB corresponding to the light receiving point. The light receiver 5 generates continuous signal voltages VA and VB corresponding to the currents IA and IB, respectively. An adder 14 adds the signals VA and VB, then sends the result to a pulse modulation circuit 2. The circuit 2 generates oscillating pulses P0, the frequency of which varies in inverse proportion to the signal VA+VB. Thus the element 1 is subjected to pulse modulation and to feedback control so that the amount of light received by the detector 5 is always kept at a fixed level even if the distance X from the measuring objective 4 varies.

Title: Photoelectrically focus detecting device mounted camera
Inventor: YAGI MICHIO
IPC: G02B7/28
Filed: 1978-10-02
Abstract: PURPOSE: To make it possible to prevent difference between actual focusing condition on film surface and focusing condition judged and displayed by machine caused by differences in range of depth of focus, by changing setting of the judging level of focusing condition in accordance with the range of depth of focus.  
     CONSTITUTION: When a light which passed through lens 1 arrives to the light receiving section of focusing condition detecting circuit 4 provided at site 2 which corresponds to the focusing plane of lens 1, detecting circuit 4 outputs electric signal V. The standard range of this electric signal varies in accordance with the difference in range of the depth of focus caused by the difference in value of lense opening as shown in the diagram (La, Lb, and Lc). The output of detecting circuit 4, therefore, can be checked whether it is in a range of depth of focus of the lens opening or not, by comparator 5 and standard value setting circuit 6, and, when it is lower than the judging level, the focusing condition can be confirmed by a lighting display of display circuit 7. Thus differences between focusing condition display of judging level and actual focusing condition can be prevented.
