Title: Document expression conversion device
Inventor: SHIBUTA KAZUO
IPC: G06F17/22
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To facilitate the understanding of a readier by adding or substituting an explanation matched with the background of a document content to/for an expression contained in the document. SOLUTION: Dictionaries recording the combination of an expression and a related explanation is held in a background-wise dictionary storage means 3 for the respective backgrounds. When a conversion instruction means 4 displays a document being an object and receives an expression conversion instruction from a user against the expression in the pertinent document, an expression conversion means 5 retrieves the dictionary corresponding to the expression which is instructed for conversion from the dictionary storage means 3, and adds the explanation to the expression which is instructed for conversion by using the dictionary. When an expression whose meaning cannot be understood exists in the document, the user (reader) gives an expression conversion instruction to the expression.  Thus, an explanation is added to the expression based on the dictionary matched with the background of the document.

Title: Low corona and low wind whistle electric wire
Inventor: ASANO YUJI
IPC: H01B5/08
Filed: 1993-09-21
Abstract: PURPOSE:To improve the corona characteristic of a low wind sound electric wire having a spiral protruded thread. CONSTITUTION:The utmost outer layer stranded wire is formed by twisting a segment element wire 11 having a low back and a segment element wire 12 having a high back, and also a spiral protruded strip 13 by the segment element wire 12 having the high back is provided on an electric wire surface. The shape of this spiral protruded strip 13 satisfies the next condition; 0.035<=h/d<=0.120, 0.025<=R/D<=0.100, wherein, D= an electric wire outer diameter in the outer peripheral surface at a place having no spiral protruded thread, (h) = the height of a spiral protruded strip, and R= the curvature radius of the edge part of the spiral protruded strip, and the spiral protruded strip 13 at the electric wire outer periphery prevents the generation of Karman's vortex to realize the effect of wind sound lowering. While through this spiral protruded strip 13 increases an electric potential gradient, but the increase of the electric potential gradient can be restrained to the minimum by forming the shape of the spiral protruded strip 13 into the above. This can reconcile the effects of wind whistle lowering and corona noise reducing.

Title: Optical scanner
Inventor: KAWAI SHIGERU
IPC: G02B5/32
Filed: 1984-12-06
Abstract: PURPOSE:To linearize easily an optional scanning line by detecting the curving condition of the scanning light emitted rom a holographic scanner and changing the wavelength of a wavelength variable light source so as to make linear the scanning lines. CONSTITUTION:The light oscillated from a semiconductor laser 1 which is a wavelength variable light source scans a scanning plane 6 by means of a collimating lens 2, a cylindrical lens 3 and a hologram lens 5 of a holographic scanner 4. A beam splitter 7 is placed in front of the plane 6 and the part of the scanning beam is taken out. The taken out beam images the light in the scanning direction to a one-diemsionally arrayed photodetector 9 by means of a cylindrical lens 8. The image is formed in such a manner that the deviation in the sub-scanning direction corresponds to the arraying direction of the photodetector 9 when the light in the scanning direction is imaged. The wavelength value which respect to the deviation is calculated from the differential output from the photodetector by an arithmetic circuit 10 such as microcomputer using the relation between the oscillation wavelength and diffraction angle. The current of a power source 11 is changed by using the relation between the injection current and oscillation wavelength. The optical scanner which permits linear scanning with the optional scanning line is thus obtd.

Abstract: PURPOSE:To provide the illumination device and liquid crystal display device which are free from unequal brightness by providing reflectors on both sides of a light transmission plate to confine the light radiated from light sources into the light transmission plate and to suppress the attenuation quantity of light. CONSTITUTION:The light radiated from fluorescent lamps 2, 2 is reflected by the inside surfaces of round parts 12, 12 and is made incident on the inside of the light transmission plate 4 made of an acrylic resin from both ends thereof. The light is refracted or reflected by the reflection surface 13 of a prism 3 or reflection plate 1 disposed below the light transmission plate 4 and is made incident on the inside of the light transmission plate 4. The incident light on the inside of the light transmission plate 4 is diffused by a diffusion board 5 and illuminates a liquid crystal display plate 6 from its rear side. Further, the light from the fluorescent lamps 2, 2 is confined into the light transmission plate 4 by the reflectors A, B provided at both ends of the light transmission plate 4 to prevent the leakage of the light from the ends of the light transmission plate 4. Consequently, the illumination in the lateral direction of the effective display surface of the liquid crystal display plate 6 is brightened and the brightness over the entire part is uniformalized.

Title: Detecting method for signal phase difference
Inventor: HOSHIKO YOSHISABURO
IPC: H03D13/00
Filed: 1986-10-31
Abstract: PURPOSE:To detect a momentary phase difference by calculating a phase angle from a ratio of a sampling value at a specific point of time to a sampling value of a delay signal and detecting the phase difference of each input trigonometric function signal from the calculated phase angle. CONSTITUTION:Sample-and-hold circuits 10-13 retarding input trigonometric signals S1, S2 of the same frequency by pi/2 by delay circuits 14, 15 respectively sample a direct, signal and a delay signal simultaneously and A/D converters 16-19 convert outputs 10a-13a of sample-and-hold circuits 10-13 into digital values respectively. As the A/D converter, an A/D polarity having polarity or an offset binary A/D converter is used to keep the bipolar sign. An arithmetic processing unit 20 decides the quadrant depending on the polarity in case of the A/D converter with polarity and depending on the judgement of the sign of a code bit in case of an offset binary A/D converter. Thus, the phase difference between two signals is obtained surely and the circuit constitution is simplified.

Title: Automatic welding equipment
Inventor: IMAIZUMI HIROSHI
IPC: B23K9/12
Filed: 1991-07-03
Abstract: PURPOSE:To maintain high productivity and to shorten welding operation by inserting a second filler metal wire into a molten pool and carrying out cooling control of the molten pool. CONSTITUTION:When a welding torch 2 and a first filler metal wire 8 move to the right ride from the left side, the second filler metal wire 13 being moved to the left side is inserted into the molten pool which is molten without being cooled by a second oscillating mechanism 14. Since the latent energy of the molten pool is absorbed when this second filler metal wire 13 is molten, cooling of the molten pool is facilitated. Further, the second filler metal wire 13 synchronizes with the movement of the welding torch 2 and the first filler metal wire 8 and executes just the opposite movement at an orthogonal axis of a weld line.

Title: Controlling method for binary generating set
Inventor: HORIGUCHI AKIRA
IPC: F01K25/10
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To dispense with a bypass pipeline and a pressure control valve by adjusting the working fluid level of an evaporator and thereby controlling the output of a screw turbine, in a device which makes a working fluid circulate in a closed loop inclusive of the evaporator, and drives a generator with this screw turbine. SOLUTION: Steam of a working fluid produced in an evaporator 2 is fed to a screw turbine 4, expanding it hereat to carry out its work and, after a generator 10 is driven, it is condensed by a condenser 6, and condensate is fed to the evaporator 2 again by a circulating pump 8. At this time, each of level gauges 18 and 20 detecting a level of the working fluid is set up in the evaporator 2 and the condenser 6 respectively, therefore a controller 22 outputs a control signal to a driving motor of this circulating pump 8 on the basis of these signals. For example, if the working fluid level of the condenser 6 is not minimal, this working fluid level of the evaporator 2 is raised up, and thereby the extent of output in the screw turbine 4 is upraised.  In brief, the rotational frequency of the circulating pump 8 is increased and the working fluid is controlled so as to be fed yet much quantity by the evaporator 2.
