IPC: A61B8/00
Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To enable distinction of a number of target points existing at an equal distance by arraying a number of sub transducers with different center frequencies at the respective positions of transducers on a plane determined by the height direction and the directions of scanning lines in such a manner as to vary the direction of emitting ultrasonic waves of the sub transducers. SOLUTION: Sub transducers with different center frequencies are each provided with an array type transducer 200 composing one transducer, a part of the structure of ultrasonic two-dimensional imaging devices 20-50 and, 1 moreover, a frequency analysis means 100. The frequency analysis means 100 is provided with a spectrum analysis part 110 to estimate an ultrasonic spectrum of a frequency beam to be applied from an A/D conversion part 50 and a 3-D re-computing part 130 which performs a computation to allow displaying of three-dimensional image information in a user's desired form. When a number of target points exist on one scanned plane, the distance to the individual target points can be learned by measuring time until an ultrasonic echo signal reaches the target points.

Title: Display device
Inventor: NISHIMURA YUKIO
IPC: G02B5/20
Filed: 1982-10-20
Abstract: PURPOSE:To obtain a display device which is excellent in driving property, productivity, durability and reliability, and has a high-density picture element by providing a display element having a light transmittable liquid layer and a radiant ray absorbing layer, a signal input means to this diplay element, and a filter. CONSTITUTION:In case when a liquid layer serving as a medium of a transmission type display element DE placed between a sechilern lens 11 and the second lattice 7b is not heated, and its physical property is smooth uniformly, incident light 14 passing through the first lattice 7a is all shielded by the second lattice 7b and does not reach a screen 12. When a light shielding filter 7c is placed at a light condensing point of a condenser lens 11b, the incident light 14 is condensed onto the light shiedling filter 7c through the condenser lens 11b. When a part of the liquid layer of the display element DE is heated and becomes a high temperature, and a liquid layer heating part 13 is formed, an optical path of light passing through that part of the display element DE is varied, therefore, the incident light 14 passing through that part reaches on the screen 12 without being shielded by the light shielding filter 7c.

Abstract: PURPOSE:To improve the color reproducibility of a color toner by using a specific resin for a liquid developer and dispersing finely an org. pigment into said developer. CONSTITUTION:The resin polymerized with the monomer A expressed by formula I (R is H or -CH3, X is -COOCnH2n+1 or -O-COCnH2n+1, n is 6-20) and the monomer B of formula II (R1 is -H or -CH3, n is 1-20, R2 is -H, Na, K, Mg, Mn, Ca, etc.) is used. Such copolymer is mixed with a coloring agent and the mixture is dispersed by an attritor, etc. together with petroleum aliphat. hydrocarbon to prepare a concd. toner. The component A in the copolymer has the property to solvent with a solvent before and after the polymn. and therefore the copolymer is dispersed in the state of bonding the component A solvent with the solvent around the component B. The component B is polar and induces the charge generation of the polymer. The above-mentioned developer can be made to have small particle diameters in a narrow grain size range. The excellent color reproducibility as the color toner is thus obtd. and the dispersion stability, shelf life, fixability, brightness, etc. are improved as the developer for general purposes.

Title: Facsimile equipment
Inventor: OKAMOTO MASANORI
IPC: H04N1/44
Filed: 1982-10-18
Abstract: PURPOSE:To prevent receive contents from being exposed when an addresses is absent by allowing a transmitter to send an address code before picture signal transmission when detecting a secret processing signal and permitting a receiver to store a picture signal in a memory corresponding to the code. CONSTITUTION:When a circuit is connected, the receiver sends an answer signal CED and a function signal GI. For secret processing, the transmitter sends a signal for switching a recording device to a storage device in a mode selection processing signal GC. When the receiver sends a phase matching end signal CFR after phase matching, the transmitter sends a code signal. The receiver specifies the picture signal memory corresponding to the code and sends a signal CFR. Then, the picture signal sent from the transmitter is stored in the picture signal memory. Consequently, transmit contents are not recorded until the address code is inputted to the receiver, so even if the addressee is absent, receive contents are not known to other people.

IPC: B23K7/10
Filed: 1987-07-24
Abstract: PURPOSE:To improve the efficiency in forming a groove by arranging integrally both nozzles of a vertical one and an inclined one at a prescribed distance and setting the offset quantity in the range smaller than the sum of the tip radiuses of both the nozzles and in the range larger than the sum of the radiuses of the cutting oxygen jet holes. CONSTITUTION:A box body 3 to fit the nozzles 1 and 2 is prepared and holes 13 and 14 are provided to its vertical part 11 side and inclined part 12 side respectively so that the bases 11a and 12a are made to one surface.

By this method, the offset interval alpha can be shortened without making cutting oxygen air currents to interfere mutually. Accordingly, the groove cutting and the shape cutting are carried out by one stage. Further, since both the nozzles 1 and 2 are integrated, a relational fitting jig is not required. By this method, the efficiency in forming the grooves is improved.

Title: Vehicle suspension device
Inventor: IWASAKI KATSUYA
IPC: B60G17/015
Filed: 1997-07-09
Abstract: PROBLEM TO BE SOLVED: To prevent damage of a vehicle in a traveling time on a rough road only by means of control of a damping force characteristic of a shock absorber without arranging any vehicle height regulating means by controlling a damping force characteristic of each shock absorber not onto an expansion stroke side but onto the side on which a pressure stroke side is hardened when a rough road is determined. SOLUTION: In a rough road traveling time, a damping force characteristic of each of shock absorbers SAFR, SAFL, SARR, SARL is controlled to the hard area in which a hard characteristic is provided on the pressure side while a soft characteristic is provided on the extension side. In this way, the damping force characteristic on the pressure stroke side is set to be higher than that on the extension stroke side, so that expansion quantity of the shock absorbers SAFR, SAFL, SARR, SARL is increased higher than contraction quantity of them when expansion and contraction of the shock absorbers SAFR, SAFL, SARR, SARL are repeated, and as a result, change in the direction, in which a vehicle gravity center height is increased, is carried out gradually.  In this way, a vehicle height can be increased in a rough road traveling time only by means of damping force characteristic control without arranging any special vehicle height regulating means.

Abstract: PURPOSE:To embody the compatibility of plate wear with fouling resistance and especially improvement of fouling resistance of a halftone part of an image by a method wherein a pit form in which a gradient of a straight line by a linear regression analysis of a pit diameter to a maximum depth normal to the pit diameter is a specific numerical value or more is set to a rough surface form of a substrate. CONSTITUTION:An aluminum substrate for lithographic printing is formed by electrolytic surface roughening treatment of aluminum or its alloy plate. In that case, a rough surface from is set to be a pit form in which a gradient of a straight line by a linear regression analysis of a pit diameter P to a maximum depth D normal to the diameter is likely to be 0.100 or more. Then, the pit diameter and depth abovementioned are defined by direct meassurement with an electron microcopic photograph. The pit diameter is a rectilinear distance between both fringes in the pit of a sectional photograph and the maximum depth is located at a position in which a depth normal to the straight line of the pit diameter becomes maximum. Thereby, plate wear is made compatible with fouling resistance, and especially fouling resistance of a halftone part of an image is improved.
