Title: Method for observing multi-core optical fiber
Inventor: WATANABE HIDEKI
IPC: G02B6/255
Filed: 1989-05-19
Abstract: PURPOSE:To easily observe an axis shift by slanting an image pickup surface at an image pickup angle to the optical axis of a microscope according to all focus positions of a real image and a virtual image which are picked up on the image pickup surface. CONSTITUTION:The image pickup surface 2 is slanted at the image pickup angle theta1 to the optical axis 3 of the microscope 1 according to all the focus position of the real image (a) and virtual image (b) picked upon on the image pickup surface 2. Therefore, optical fibers alpha0 and beta0 arranged on an operation surface L slanting at an optical axis angle theta1 to the optical axis 3 form images on alpha and beta on an image pickup surface P through an objective 4. Then the image pickup surface 2 of an image pickup device is arranged matching the position of the image pickup surface P (focus positions of all optical fibers to be picked up). Consequently, images can be picked up so that all the arrayed optical fibers alpha0 and beta0 are in focus at the same time, and the lens barrel of the microscope 1 is shortened to reduce the size of an observation position.

Title: Carrier reproducing circuit
Inventor: HONDA MASANORI
IPC: H04L27/227
Filed: 1980-09-10
Abstract: PURPOSE:To make unnecessary a virtual drawing prevention circuit, sweep circuit and temperature compensating circuit, by providing a frequency discriminator in which the carrier frequency is set in advance. CONSTITUTION:A frequency discriminating circuit 21 discriminates the frequency of carrier of an input signal S, that is, signals of frequencies other than this frequency only are passed through. Thus, when a phase locked loop circuit (PLL) is drawn in an artificial drawing frequency, the output signal of a voltage controlled oscillator (VCO)5 passes through the frequency discriminating circuit 21, resulting that the output voltage of a low pass filter 23 is increased. AFC is given to the VCO5 with this output voltage and the PLL circuit is outside the artificial drawing frequency. When the PLL circuit is drawn in the carrier drawing frequency, the potential of the output signal of the frequency discriminating circuit 21 is zero, thus the potential of the low pass filter 23 is also zero and no AFC is given to the VCO5. Thus, when drawing is made once to the carrier drawing frequency, the frequency is kept to this drawing frequency.

Abstract: PURPOSE:To make proper management control over a production line performable so easily in a short time, by setting an operating pace, giving it to the production line as an operating pace instruction and, if the occurrence of trouble in the production line is judged from the compared result between an operating state of the line and the operating pace, extrapolating a countermeasure for the trouble and indicating it. CONSTITUTION:When a production line 1 is operated, a trouble countermeasure indicating part 7-2 collects data on an operating state of the production line 1 and compares it with the set operating pace. And, if the compared result comes to be out of the specified range, the trouble countermeasure indicating part 7-2 judges it to be trouble occurrence, and an inquiry to the part judged as trouble is made to an inference engine 8. If so, this inference engine 8 extrapolates the cause of the trouble occurrence in a systematic manner in regard with the troubled part, and the extrapolated result is fed to the trouble countermeasure indicating part 7-2. And, knowledge data of a lowermost position of the extrapolated result in informed as a main trouble countermeasure with a CRT display unit 4, feeding it to machining and conveying systems as an operation control signal. Accordingly, management control can be done easily in a short time.

Title: Liquid crystal display device
Inventor: OKAMOTO SHINICHI
IPC: G02F1/1335
Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To prevent poor visual recognition caused by the deterioration of the contrast ratio at the time of displaying in a liquid crystal display device which is capable of switching between information display and a mirror by switching a mode. SOLUTION: In this liquid crystal display device, a scattering mode type-liquid crystal panel 2, in which the entire surface is capable of switching between the transparent state and the slightly opaque state, is disposed on the rear surface of a liquid crystal panel 1 for information display for positively displaying information such as time, and further, a mirror-finished surface plate 3 is disposed on the rear surface thereof. At the time of displaying the liquid crystal panel 1 for display, a liquid crystal panel 2 for the background is placed in a state of slightly opaque, not allowing the visual recognition of the mirror- finished surface plate 3, and display is made in a white background, thus the contrast ratio of the information display becomes high without being affected by the surrounding environment.  In contrast to this, when the liquid crystal panel for display is in a state of non-display, the liquid crystal panel for the background is placed in a transparent state, thus the mirror- finished surface plate is visually recognized by transmitting through both the liquid crystal panels, and is usable as a mirror. The liquid crystal display device serves both as the information display and a decorative panel, when a decorative plate, on which patterns are drawn, is used in place of the mirror-finished surface plate.

Title: Device for detecting load of crane

Filed: 1988-05-25
Abstract: PURPOSE:To economically detect a load without increasing sheaves by detecting a hoisting load with a sheave provided coaxially with the linking pin of two links which are provided on two members the angle between which is relatively varied. CONSTITUTION:A sheave 4 is provided coaxially with the linking pin 3 of first and second members 1, 2 the angle between which is relatively varied. The sheave 4 is supported by first and second links 7 and 8 which are vertically revolvably provided on the first and second members 1 and 2 respectively. Winding drums or sheaves 5 and 6 are provided on the other ends of the first and second members 1, 2 respectively. Lines connecting the revolving centers 7a, 8a of the links 7, 8 to the axis 3 of the sheave 4 are parallel to ropes 9 put around the sheaves 5/6 and the sheave 4, and a resultant force T acts on the shaft of the sheave 4 because of the tensile forces P of the ropes 9. Although the resultant force T is changed when the winding angles of the ropes 9 with respect to the sheaves 4-6 are varied, the components of force in the axial direction of the links are equal to the tensile forces P. Hence, by measuring the resultant force T, load can be economically measured.

Title: Hydraulic shock absorber
Inventor: IMAIZUMI TOMIO
IPC: F16F9/348
Filed: 1989-05-19
Abstract: PURPOSE:To generate damping force in accordance with a frequency generated in a vehicle body by connecting communicating passages of partition members to damping force adjusting chambers through oil passages provided with orifices in the ways, and providing fulcrum changing members for changing fulcrums at the time of opening disc valves in accordance with rise of oil pressure in the adjusting chambers. CONSTITUTION:Pressure rise in damping force adjusting chambers 31, 31a is suppressed by orifices 36, 36a in oil passages 35, 35a, on account of an increase in the frequency of change in pressure in an upper chamber 15 and a lower chamber 16, at a time of running on a bad road and the like. On behalf thereof, the positions at which backup discs 39, 39a abut on disc valves 25, 25a come inward in radial directions of the valves 25, 25a, and small damping force is generated, because abutting positions become fulcrums at the time of opening the valves 25, 25a. Also, as the frequency of change in pressure in the upper and lower chambers 15, 16 becomes low at a time of turn of the vehicle and the like, pressure rise in the adjusting chambers 31, 31a can not be suppressed by the orifices 36, 36a. Therefore, as the fulcrums at the time of opening valves 25, 25a are changed in outward direction after the oil pressure in adjusting chambers 31, 31a is raised, large damping force is generated.
