Title: Distance-measuring apparatus
Inventor: ADACHI TADASHI
IPC: G01B11/00
Filed: 1999-01-20
Abstract: PROBLEM TO BE SOLVED: To highly accurately measure a distance with reducing influences of noises of light- receiving elements by providing a light-receiving means with two kinds of light-receiving elements one of which responds slower than the other and has a higher sensitivity than the other. SOLUTION: A light-projecting means 10 projects to an object to be measured a projection light F which is modulated by a modulation signal of a mixture of a pulse signal and a reference signal. A reflecting light R of the projection light F reflected by the object to be measured is received by a first light-receiving element 22 and a second light-receiving element 23 of a light-receiving means 11 independently and concurrently. A first measuring part 12 detects a time difference between a pulse signal component of a first receive signal of the reflecting light R detected by the first light-receiving element 22 and a pulse signal component of the projected light. A distance to the object to be measured is schematically calculated from the time difference.  A second measuring part 13 detects a phase difference between a reference signal component of the second receive signal of the reflecting light R detected by the second light-receiving element 23 and a reference signal component of the projected light. Then, information on a distance within one phase difference to the object to be measured is calculated from the phase difference. A distance-calculating part 14 calculates a distance to the object 2 to be measured on the basis of the schematic calculation result of the first measuring part 12 and the distance information of the second calculating part 13.

Title: Optical amplifier
Inventor: MORI TSUNEO
IPC: H01S3/067
Filed: 1993-01-27
Abstract: PURPOSE:To sufficiently reduce loss when an optical amplifier is assembled to form part of an optical communication system. CONSTITUTION:A transmitting optical fiber 17 is oriented and fusion-bonded to the vicinity of an incident end of an amplifying optical fiber 8 having a sufficient length to energize, inductively radiate an energized laser light, amplify a transmitted laser light in an optical amplifier to form an optical multiplexer 6. Since the multiplexer 6 is formed of the part of the fiber 8, a fusion-bonded part for connecting when assembled in an optical communication system can be largely reduced. Thus, a connecting loss can be reduced, and a substantial amplifying effect is enhanced.

The inside layer 2 is integrated in an entangled condition with the network sheet 4 as well as the entanglement between fibers constituting the inside layer 2. At least fibers positioned on the most outside surface of the outside layer 3 are formed into loops and the density of the outside layer 3 is low causing a low entangled condition of the outside layer 3. Thus various kinds of dust from dust on a general floor to dust on a desk and furniture with a smooth surface and plastic products, further, comparatively large dust such as bread crumbs, eraser dust, etc., can be collected.

IPC: F16C32/06
Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To provide a throttle valve having a stable pressure characteristic and easy to adjust pressure when a low-viscosity operating fluid is used. SOLUTION: This throttle valve is constituted of a female screw 11 and a male screw 12 coupled with each other, and a passage in which an operating fluid flows is formed with a gap 17 between the root 15 of the screw thread 13 of the female screw 11 and the crest 16 of the screw thread 14 of the male screw 12. A passage having a small cross sectional area and long distance can be realized for the passage of the operating fluid by this throttle valve. The effect of an abrupt pressure change at the inlet portion of a throttle valve, which becomes a problem when a low-viscosity operating fluid is used, can be made relatively small, thereby a stable pressure characteristic can be obtained even when the low-viscosity operating fluid is used. The pressure of this throttle valve can be finely adjusted easily by properly setting and changing the coupling length of the screws 11, 12.

In this case, an 'L' picture is given to picture 1, 3 as shown in figure by a switch 19 and an 'H' signal is given to pictures 2, 4 in the most significant address. The processing above is given similarly to the line address. Thus, the picture of plural fields is stored in one field memory with compression.
