Title: Nurbs curved surface plotting method
Inventor: KUBOTA ATSUSHI
IPC: G06T15/00
Filed: 1992-12-03
Abstract: PURPOSE:To provide a NURBS curved surface plotting method capable of accurately plotting a curved surface in a three-dimensional space. CONSTITUTION:A geometrical processor maps the vertex of a rectangular on a surface to store the position of the vertex in the three-dimensional space in a corresponding vertex data structure. Next, after mapping all the four vertexes of the rectangular on the flat surface, the vertex normals of the four vertexes of a poligon in the three-dimentional space corresponding to the rectangular on the flat surface is obtained, these vertex normals are written in a surface data structure corresponding to the pertient poligon and at the same time, each of the obtained vertex normals are stored in the corresponding vertex data structure. A processing like this is executed for all the rectangulars on the flat surface and next, a pologon with a vertex normal is prepared by referring to the surface data structure and the vertex data structure to output it. A plotting processor processes plotting based on the poligon with the vertex normal.

Inventor: HOSIER PAUL A
IPC: G01J1/02
Filed: 1998-11-16
Abstract: PROBLEM TO BE SOLVED: To enable a circular P layer to operate as an electric charge collector and at the same time minimize the entire capacitance of a photodiode by allowing a polysilicon layer to essentially cover a gap and to be spread onto one portion of an exposure region and onto one portion of an oxide layer immediately outside the gap. SOLUTION: A gap 14 that nearly follows the entire shape of a polysilicon layer 12 is provided in a field oxide 10. More specifically, although the polysilicon layer 12 is spread around the partial assembly of a region where a contour is determined by the field oxide 10, as a whole, the gap 14 is located directly below the polysilicon layer 12. In this case, one portion of the polysilicon layer 12 spreads exceeding the edge of the gap 14 and partially overlaps with one portion of the field oxide 10 at both sides of the gap 14. Also, a relatively thin, for example approximately 180 Å, protection layer (a gate oxide 15) of the field oxide is placed between the gap 14 and the polysilicon layer 12.

Title: Capacitor charging circuit
Inventor: YAMAGATA SHIGEO
IPC: H02M7/06
Filed: 1991-12-10
Abstract: PURPOSE:To enable a capacitor to be charged smoothly even if a power supply voltage varies by changing a charging switching voltage in response to fluctuation of the power supply voltage in a capacitor-charging circuit where a current- limiting resistor is short-circuited after the capacitor is charged to a charging switching voltage setting value through the current-limiting resistor. CONSTITUTION:A title item is provided with a transformer 21 for an instrument which detects an output voltage of an AC power supply 2 and a power supply voltage detector 22 and then allows the detected voltage to be input to a charging switching voltage modification circuit 20. When the output voltage of the AC power supply 2 fluctuates a charging switching voltage which is fed to a comparator 13 also is changed in conjunction with the voltage fluctuation, thus enabling a ratio for the power supply voltage of the charging switching voltage when short-circuiting a current-limiting resistor 3 to be nearly constant. Therefore, even if the power supply voltage fluctuates, inconveniences where the current-limiting resistor 3 cannot be short-circuited and charging incompletion state continues and a large charging inrush current occurs when short- circuiting the current-limiting resistor 3 can be avoided.

Title: Chinese character converting method for portable terminal
Inventor: KIRIHARA RYOJI
IPC: G06F3/0489
Filed: 1998-11-16
Abstract: PROBLEM TO BE SOLVED: To provide a KANJI (Chinese character) converting method with superior operability for a portable terminal which enables a user to confirm characters to be actually registered without getting confused when registering a series of characters including KANJI. SOLUTION: When a character string 'Yokohama' is inputted by using a 10-key after KANJIs standing for 'mobile communication' is determined on a screen 104, KANJIs standing for 'Yokohama' are displayed in a reversed state (screen 108) right behind the KANJIs 'mobile communication'. When a 'reception history/↓' key is pressed in this state, 'Yokohama' in KANJI is not displayed on the screen, but only the character 'Yoko' in KANJI is reversed and displayed behind 'mobile communication' (screen 110), and an alarm sound is outputted. When the character 'Yoko' in KANJI is reversed and displayed on the screen 110, a determining operation is not done yet, so the conversion of 'Yokohama' into KANJI can be retried by pressing the 'reception history/↓' key.  When a 'telephone book/select' key is pressed in this state, 'mobile communication Yoko' is determined and its characters are registered.

IPC: A61L2/14
Filed: 1998-11-02
Abstract: PROBLEM TO BE SOLVED: To remarkably reduce the release of hydrogen peroxide from a sterilization chamber by a method in which gas from the chamber containing hydrogen peroxide vapor is passed through a member bed which is coated with a noble metal catalyst for hydrogen peroxide and arranged in a channel to convert the hydrogen peroxide into hydrogen and oxygen. SOLUTION: In a sterilization chamber 12, usually, exhaust is done into an atmosphere in the chamber including a sterilizer 10 through its outlet 16. A vacuum pump 18 is installed in such an exhaust system, gas is sucked from the chamber 12 by the actuation of the pump 18 and sent from the outlet 16. In this process, when the gas in the chamber 12 is discharged, the pressure in the inside is reduced to 0.5 Torr or below by the pump 18. Next, hydrogen peroxide is introduced into the chamber 12, and the pressure in the chamber 12 is restored to about 10 Torr. By catalyst converters 20, 22 installed in the upper and lower flows of the pump 18, the hydrogen peroxide in the gas passing through a channel 14 is converted into oxygen and hydrogen by a catalyst to reduce the concentration of hydrogen peroxide at the outlet 16.

Title: Illumination system and liquid crystal display device using it
Inventor: KUREMATSU KATSUMI
IPC: G02F1/13357
Filed: 1994-12-27
Abstract: PURPOSE: To prevent the temperature rise of a liquid crystal panel and to excellently maintain the display characteristic thereof. CONSTITUTION: Light from fluorescent lamps 2,$ is transmitted through a transparent substrate 6 and an infrared-rays reflection layer 12 after the light quantity distribution thereof is uniformized by a lighting curtain 5. Then, when it is transmitted through the layer 12, infrared rays are reflected toward the lamps 2,... side and eliminated. Besides, the angular distribution of the light transmitted through the layer 12 is uniformized by a diffusion plate 7 and the liquid crystal panel is irradiated with it. Therefore, since the infrared rays are eliminated from the light irradiating the liquid crystal panel, the temperature rise of the liquid crystal panel is prevented due to the irradiation of the infrared rays. On the other hand, since an air flow is formed at gap parts S1 and S2, the heat of the layer 12 and the plate 7 is forcibly eliminated. Therefore, the heat is suppressed to be transmitted to the liquid crystal panel from the plate 7.

CONSTITUTION:The switching element is formed as the thin-film two-terminal element interposed with the hard carbon film 2 between the 1st conductor 1 and the 2nd conductor 3. In addition, the standard deviation of the distribution of the current values within the substrate plane of the respective thin-film two-terminal elements at the time of impression of the specified voltage is confined to <=35%, more preferably <=18% of the average value. The distribution of the film thickness, specific resistance and specific dielectric constant of the hard carbon film is required to be confined to the specified value or below in order to confine the standard deviation of the distribution of the current values within the substrate plane at the time of impression of the specified voltage to the specified value or below. The formation of the above-mentioned matrix at a relatively low temp. with the simple stage is possible in this way and the device design in a wide range is executed by using the insulating film (hard carbon film) having excellent film controllability and mechanical strength and low dielectric constant. In addition, the fluctuations in the element characteristics are decreased.
