Filed: 1998-06-22
Abstract: PROBLEM TO BE SOLVED: To improve the handling property by providing unevenness whose mean roughness is not less than a specified value on the surface of a film to eliminate entanglement between films without damaging the excellent flexibility and adhesivity. SOLUTION: Unevenness is provided on a surface of a film. The uneven pattern is not limited, and the uneven pattern at random or specified intervals is acceptable. The degree of unevenness (roughness) is approximately not less than 40 nm, preferably approximately, 40 nm to 1 mm, especially preferably, approximately 200 nm to 1 mm in mean roughness (Ra value) measured by using a stylus type surface roughness needle under the condition of approximately 5 μm of stylus size and approximately 50 mg in stylus pressure. In a non- extended condition, the film surface is uneven, the adhesivity is not present between films, and the films are not entangled with each other, and the handling property is excellent. During the wrapping, the film is expanded, its unevenness is not present, and the adhesivity and flexibility specific to the film are restored.

Title: Processing method of high speed polygon
Inventor: NODA HIDEO
IPC: G06T11/40
Filed: 1998-06-22
Abstract: PROBLEM TO BE SOLVED: To save memory and to accelerate data processing in a painting-out process of a polygon by forming a polygon in a band which neglecting the vertexes of the polygon except the band under processing, and painting out this polygon. SOLUTION: When vertex coordinates of a polygon and transferred from a CAD system which being paired with a paint-out command, a CPU stores the coordinates of all the vertexes (a) to (p) of the polygon as intermediate codes. Whole picture printed out is divided into plural band pictures having a band width corresponding to a longitudinal length of a head. A polygon is formed in a band while neglecting polygon vertexes except those under processing, so that this polygon is painted out. For example, in the band 4, each of the polygon vertexes (a), (b), (g) to (k), (o), (p) except the band 4 is neglected (A), the vertexes (c) to (f) and the coordinates 1 to (n) are stored (B). The CPU operates the paint-out process of this polygon. In the other bands similar processes to that in the band 4 are operated.

Title: System, method and product for adding object service to binary class in object-oriented system
Inventor: GAIREINE KANTEIN
IPC: G06F9/44
Filed: 1996-07-04
Abstract: PROBLEM TO BE SOLVED: To automatically insert the object service of persistency, simultaneity, restorability, security and distribution, etc., to a binary object class. SOLUTION: The description of a class is registered in a name service context. For a desired restriction for an attribute, the name service context of a class object like a factory provided with it is searched and whether or not the object can be operated in a prescribed operating environment is judged. At the time, an object service restriction is excluded. When the class is found by a search, the class already supporting the object service restriction is selected first and the class object provided with a desired object service function is prepared in the operating environment. In the case that an original class does not provide a desired function, a specified object service function is added and returned to a calling side.

Title: Processor that processes load instruction with latency
Inventor: EHAMA MASAKAZU

Filed: 1996-07-04
Abstract: PROBLEM TO BE SOLVED: To make logical area hard to become larger than that in a score boarding even if computing elements increase in number fast by guaranteeing the latency used as a source after a load instruction was issued. SOLUTION: Register state managing circuits 2 each have a valid bit storage means, a storage means for an object register number of a load instruction, and a counter which stores the latency and decreases the latency for every clock cycle; when the value of the counter reaches a specific value, a stall signal is outputted on condition that a valid bit is effective, and if the valid bit becomes ineffective during the output of the stall signal, the output of the stall signal is quit. An OR circuit 3 ORs stall signals outputted from managing circuits 2 and outputs the result to a computing element.  When the load instruction is issued, a signal processor 1 stores the object register number and latency in a managing circuit 2 whose valid bit is ineffective to make the valid bit effective, and makes the valid bit of a managing circuit 2, which has the register number after the completion of writing, ineffective.

Title: Apparatus for hardening high-molecular resin layer
Inventor: ENDO ATSUSHI
IPC: B05C9/14
Filed: 1986-07-24
Abstract: PURPOSE:To form a homogenous insulating resin film within a short time, by successively guiding a substrate having a high-molecular resin layer formed thereto into a hardening oven by the movement of a feed belt and hardening the resin layer by the irradiation of a microwave. CONSTITUTION:The substrate 2 successively placed on a specimen feed belt 1 is fed in a curing oven 3 from a inlet 4 with the movement of the belt 1 and moves at a constant speed through the oven 2 while receiving the irradiation of the microwave from a microwave generating unit 6 and fed out to the outside from an outlet 5. Since the substrate 2 moves at a constant speed in the furnace, a hardening treatment time by the irradiation of the microwave becomes uniform at every substrate and the uniformity and reproducibility of the film being fomred are enhanced and productivity is high because of a short treatment time.

Title: Image forming device
Inventor: TANAKA KAZUMOTO
IPC: G03G15/05
Filed: 1982-10-05
Abstract: PURPOSE:To maintain the level of an image density always at a specified level for a long period of time by performing automatically and mutually relationally the calibration of the level of the image density in the group of multicopying and the calibration of the same level between the multicopying groups. CONSTITUTION:A signal which increases successively an outut voltage is inputted successively selectively from the eight terminals 231-238 of a microcomputer 22 to the input of the control signal for the output voltage of a high voltage transformer 20 according to progression of multicopying, by which the voltage to be impressed on an electric discharger 12 is increased stepwise. The successive decrease in the image density in the multicopying group is thus automatically compensated and the image density of each copy in the multicopying group is made constant. On the other hand, when a screen drum 1 is used increasingly, the resistance value of a variable resistor VR9 is turned in a decreasing direction, and the phonomenon in which the contrast of the initial potential of the latent image formed by the drum 1 decreases is leveled up, and the level of the image density between the multicopying groups is maintained at a specified level. The level of the image density is thus maintained at a specified lever for a long period of time.

Title: Liquid crystal display device and its production
Inventor: NAKAYAMA NORIO
IPC: G02F1/1368
Filed: 1996-07-04
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device which minimizes the stages to be added, has stable characteristics and does not induce deterioration in grade, such as crosstalks, in image quality. SOLUTION: The channel regions of an amorphous silicon layer 37 have high resistance as well when a source electrode 34 and a drain electrode 36 are held insulated from each other. A region where first and second gate insulating layers 42, 43 and a gate electrode 44 are laminated in the upper part beyond the end of this amorphous silicon layer 37 is connected with the high resistance to two lowresistance regions 39, 40 electrically connected to the source electrode 34 or the drain electrode 35. The degradation of the insulation characteristic between the source electrode 34 and drain electrode 35 of a thin-film transistor(TFT) 46 itself does not arise and leak currents, etc., are not generated.  When the source electrode 34 and the drain electrode 35 are held conducting, the channel regions of the amorphous silicon layer 37 turn to the low resistance but since the characteristic itself of the TFT 46 is conducting, thereby the generation of the leak currents are of no problem.
