Inventor: NAGAOKA TADAYOSHI
IPC: B01D29/15
Filed: 1991-08-09
Abstract: PURPOSE:To prevent damage and deformation of a screen upon press-fitting thereof, by circumferentially laying a plurality of rods outside of screen wires so as to hold them by an annular rod holding part, and by winding a protecting wire around the rods. CONSTITUTION:When a screen passes 10 through a curved part of a well upon press-fitting of the screen 10, a protecting frame 12 composed of a protecting rod 16 and the protecting wire 18 slides making contact with the wall surface of the curved part of the well. After a screen wire 15 is resiliently deformed and curved inside of the protecting frame 12 without making direct contact with the wall surface of the curved part of the well, when the screen 10 reaches a horizontal part of the well, the screen 10 is restored into its original shape. A predetermined space (g) is defined between the protecting rods 16 and the screen wire 15, and is adjusted to a suitable value so that the screen 15 does not make contact with the protecting rods 16 or is prevented from being deformed even though it makes contact with the rods 16.

Title: Optical-fiber magnetic field sensor
Inventor: TSUCHIDA NORIHIRO
IPC: G01R33/02
Filed: 1999-08-10
Abstract: PROBLEM TO BE SOLVED: To obtain an optical-fiber magnetic field sensor whose sensor sensitivity can be enhanced by separating the optical fiber guide of a sensing part in an optical fiber from the optical fiber guide of a reference part. SOLUTION: In this magnetic field sensor, a permanent magnet 4 is installed in advance between both ferrite magnetostrictive vibrators 1, and a magnetic field is applied to the inside of the ferrite magnetostrictive vibrators 1. When it is subjected to the magnetic field from the outside, the ferrite magnetostrictive vibrator 1 on one side is expanded, and the ferrite magnetostrictive vibrators 1 on the other side is contracted. Consequently, when optical fibers 6 are bonded to the ferrite magnetostrictive vibrator 1, the optical fibers 6 are expanded and contracted. The phase of light which passes the inside of the optical fibers 6 is changed, and the magnetic field can be detected.  In this case, when the guide part 2 of a sensing part and the guide part 2 of a reference part are separated into a guide 2A and a guide 2B, the sensing part and the reference part are deformed independently. Consequently, it is possible to prevent the degradation of the sensor sensitivity of the magnetic field sensor. In addition, the optical fiber of the sensing part and that of the reference part are expanded and contracted in opposite directions, and the sensor sensitivity can be doubled.

Title: Clock reproducing circuit of magneto-optical disk device
Inventor: YUKI YOICHI
IPC: G11B7/00
Filed: 1992-08-25
Abstract: PURPOSE:To enhance responsiveness and also to stably keep locking. CONSTITUTION:When an MO signal is inputted in a PLL circuit 8, a time constant change-over switch 29 connects a time constant circuit 30 to an arithmetic amplifier 28. At this time, the time constant circuit 31 is not connected to the arithmetic amplifier 28 so that capacitors CY1 and CY2 excute self-discharge. Then, when an ID signal is inputted, the time constant change-over switch 29 connects the time constant circuit 31 to the arithmetic amplifier 28. Since the capacitors CY1 and CY2 have almost no electric charge, the capacitors CY1 and CY2 are charged. Thus, the time constant of a low pass filter 26 transitionally becomes smaller than the normal time constant of the time constant circuit 31 till charge is completed and becomes the normal time constant when charge is completed. In the same way, when the time constant circuit 30 is connected to the arithmetic amplifier 28 from the self discharge state of the capacitors CX1 and CX2, the time constant of the low pass filter 26 transitionally becomes small.

Abstract: PROBLEM TO BE SOLVED: To miniaturize a scanning mechanism which changes an image-pickup range and to improve scanning precision by independently driving micromirrors, which is disposed at a mirror guiding the light of a subject to an image-pickup sensor and scanning it, corresponding to a scanning position. SOLUTION: A micromirror array 15 is an aggregate of batch-formed micromirror elements with many mirrors (micromirrors) (m) such as a straight belt. The turning angle of each mirror (m) is changed from one tip side in sequence so as to sub-scan. For a period for scanning a single line, one-line area in a subject formed on a virtual image forming surface through a lens 12 is projected to a line sensor. At this time, the mirror (m) for the entry of subjective light outside of a projecting object comes into a saving state that the light of the subject is ineffective.  For example, at the time of scanning a heading line, a first mirror (m) is arranged by tilting at an angle in a mirror disposing direction, the other mirrors (m) are also arranged in the state of tilting at a prescribed angle to use from the first to seventh mirrors (m) for projection and to make the eighth mirror and after this in a saving state.

Abstract: PURPOSE:To measure the distance from a reference line to an object of measurement with high precision by converging light which is irradiated at right angles to the reference line and reflected by the object of measurement by a lens whose optical axis is slanted by a specific angle to the reference line. CONSTITUTION:This instrument consists of the reference line 1, a light emitting element 2, a reflecting mirror 3 which is placed at one end of the reference line 1, the lens 4 arranged at the other end of the reference line 1, a CCD element 5, and a signal processing circuit 6. The reference line 1 is the reference for distance measurement. Then, the reflecting mirror 3 reflects light 11 at right angles to the reference line 1 and this light 11 forms a bright point 10 on the wall surface 12 of a tunnel. Then, the lens 4 installed at a constant angle to the reference line 1 converges the light from the bright point 10 to form an image of the bright point 10 on the element 5. The output signal of the element 5 is processed by the circuit 6 to calculate the position of the center of gravity of the image. Then, this position of the center of gravity is used to determine which direction of the optical axis of the lens 4 the bright point 10 is in. The distance between the reference line 1 and wall surface 12, i.e. height of the wall surface is calculated from the direction, the length of the reference line 1, and the tilt angle theta of the optical axis of the lens 4 to the reference line 1.
