Title: Three-dimensional object description processing method
Inventor: HORIKOSHI TSUTOMU
IPC: G06T15/00
Filed: 1990-08-13
Abstract: PURPOSE:To automatically judge projecting and recessing parts and to enable a modeling by discriminating coordinate data which exist at outside and inside parts from the surface of an approximate function searched by the coordinate data, operating a spherical surface projection and a labeling, operating the prescribed description of the approximate function, and operating a set operation. CONSTITUTION:A function approximating means 10 of a microprocessor control part 4 approximates the shape of a super two-dimensional function to the shape of an inputted object by the method of least squares from input range data, and transmits an approximate functional parameter to both a storage device 3 and an inside and outside judging means 11. The means 11 judges whether each point of the data exists at the inside part or at the outside part from the surface of the function, and projects the positions of the coordinate data on the spherical face after discriminating the inside from outside parts. A labeling means 12 operates the labeling in every set area of the coordinate data on the spherical face. Then, a data dividing mean 13 divides the data at every label, and a set arithmetic means 14 describes the function as the positive and negative function and operates the set operation based on this data. Then, the modeling can be expressed by the projecting and recessing parts judged automatically.

Title: Thermodynamical power generator using three-component working fluid
Inventor: REIMONDO FURANSHISU DORUNEBITS
IPC: F01D15/10
Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To take the more power from a fixed head source, in a device for generating a power by expanding a pressurized operating fluid through a turbine, by using a three-component operating fluid formed of water, ammonia and carbon dioxide. SOLUTION: In this device, a three-component operating fluid formed of a mixture of carbon dioxide of vapor phase, ammonia and water is used. This operating fluid creates a mixture of NH3 , NH4 <+> , OH<-> , H<+> , CO2 , H2 , CO3 , HCO3 <-> , CO3 <-2> and NH2 CO2 <-> dissolved in water in liquid phase. These liquid phase components form a solution easily dissolved in water under a low temperature of about 100 deg.F (38 deg.C). According to the rise of the temperature, these liquid phase components are decomposed to form water, ammonia and carbon dioxide. The use of this three-component fluid mixture allows the more efficient use of energy of low level since a steam flow of high capacity is generated in carnot cycle so as to evaporate the mixture in the Rnakine cycle.

Title: Electric-discharge-lamp starting device
Inventor: TANIKAWA KOUICHIROU
IPC: H01J61/54
Filed: 1981-12-29
Abstract: PURPOSE:To shorten wasteful time taken from application of power until starting of preheating, and shorten the starting time of an electric-discharge lamp by installing a quick-acting movable electrode, which is made of a bimetal, has a small heat capacity and has a high sensitivity, in such a manner that it faces to a fixed electrode, and connecting the quick-acting movable electrode to the terminal of a main movable electrode. CONSTITUTION:A quick-acting movable electrode 6 is heated by designing the distance between the electrode 6 and a fixed electrode 1 and the like so that glow electric discharge develops between the electrodes 6 and 1. Since the electrode 6 has a small heat capacity and is a quick-acting electrode having a high sensitivity, it curves satisfactorily rapidly compared to the usual glow electric-discharge tube until the space formed between the electrodes 1 and 6 is closed. As a result, a current flows through a circuit consisting of a terminal 4, a heater 7, the electrode 6 and the electrode 1, and heats the heater 7. Then, a main movable electrode 2 made of a bimetal is heated and immediately curved, the space formed between the common electrode 1 and the electrode 2 is closed, and a preheating current flows between a terminal 3 and the terminal  4. Consequently, the starting time of an electric-discharge lamp can be shortened by decreasing wasteful time taken until the preheating current begins to flow.

Abstract: PROBLEM TO BE SOLVED: To perform the cutting-off or bending operation of a lead smoothly, and connect the lead surely to the electrode pad on a printed board, by constituting a tie bar part by the continuation of coupling parts and bored parts. SOLUTION: Since the bar part 12 is constituted by the continuation of a coupling part 121 and a bored part 122, if these temperatures drop after these are brazed at specified high temperatures, tensile strength occurs in the tie bar part 12, based on the difference between a ceramic package and a lead frame 10, and by this stress, the peripheral walls 122a surrounding the bored part 122 through the coupling part are pulled in the longitudinal direction of the tie bar part 12, and the bored part 122 is drawn into flat shape. Thereupon, the stress is released, and the occurrence of distortion in the form of a curve is prevented, and also the shrinkage in longitudinal direction of the tie bar part 12 is relatively prevented, and the position of the lead terminal 13 on the side of the tie bar part 12 is maintained in its former condition.  As a result, the cutting off, etc., of the lead wire 13 can be performed smoothly.

Title: Vertical load control device
Inventor: OSHIDA KEI
IPC: B60G17/015
Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To secure appropriate control and stabilized moving condition in the route traveling control for automobile by controlling a vertical load so as to be returned to a normative value in the case where a movement of a vehicle is deviated from the normative value by the influence of external disturbance. SOLUTION: Normative yaw rate and a normative lateral G are computed (ST7) in consideration of a coefficient friction on a road μ, and displacement of route is discriminated on the basis of a difference between the normative yaw rate and a real yaw rate and a difference between the normative lateral G and a real lateral G. In the case where this difference is large, since it takes time to correct in the ordinary automatic steering condition, correction is positively performed (ST9). Namely, a servo valve is driven so that a target load and a real load coincide with each other, and an actuator generates the stroke so as to generate the vertical acceleration for increasing the tire grounding load in any one of a mass on a spring and a mass under the spring.

Abstract: PURPOSE:To improve the brightness of the screen of a liquid crystal projector and to expand the angle of visual field thereof by superposing translucent sheets having plane incident surfaces and projecting exit surfaces on each other. CONSTITUTION:This screen 11 is constructed by superposing the many translucent sheets 12 on each other.
