Title: Wiring board
Inventor: ITO TAKESHI
IPC: H05K1/11
Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To prevent lowering of electric characteristics by allowing the top-view shape of an outer peripheral insulating part of a wide-area metalized layer, where an opening part is formed to comprise a long axis and a short axis, so that a short failure between a via hole conductor and the wide-area metalized layer is prevented, while overlapping between adjoining outer peripheral insulating parts is eliminated. SOLUTION: A part at the periphery of a via hole 2, where no wide-area metalized layer 3 is formed, is an outer peripheral insulating part 4 whose top-view has prescribed a long axis 5 and a short axis 6. The top-view shape of the outer peripheral insulating part 4 expands in the direction vertical to the straight line connecting the centers of adjoining via holes, and the outer peripheral insulating part 4 is so formed that the short axis 6 is positioned on the straight line connecting the centers of adjoining via holes. With the use of the wiring board, a wide-area metalized layer is present between adjoining via holes, so a short circuit failure is avoided while lowering of electrical characteristics is prevented.

IPC: G06T7/00
Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To enable three dimensional restoration that reduces a noise effect and an approximation error by generating a pseudo perspective camera model by using intermediate quality between a perspective conversion camera model and a weak perspective conversion camera model. SOLUTION: A point X in three dimensional space is projected to a point xP of an image plane (Z=f) with a perspective conversion camera model, the point X is once projected to XC on a plane (Z=ZC) in parallel with an optical axis with a weak perspective conversion camera model and is later projected to a point xW on the image plane. Here, a pseudo perspective conversion camera model which has intermediate quality between the perspective conversion camera model and the weak perspective conversion camera model is produced. A projection point xQ by the pseudo perspective conversion camera model is obtained by such a manner that a point XQ which divides between the point XC and the point X internally with α:(1=α) is projected by the perspective conversion camera model.  Thus, the three dimensional restoration that is more accurate than the weak perspective camera model is enabled by using the pseudo perspective camera model about image data photographed by a stereo camera.

Title: Control method and controller for resonant power converter
Inventor: FUKAZAWA KATSUMI
IPC: H02M7/5387
Filed: 1995-06-14
Abstract: PURPOSE: To suppress a control delay and losses in a main resonant circuit and an auxiliary resonant circuit to the minimum necessary level by a method wherein the operation time of the resonant circuit is changed in accordance with a load current so as to make a current which is supplied when a switching device is turned off constant. CONSTITUTION: In a gate control circuit GCON, a load current IL is detected by a current detector CT3, the detected current signal is inputted to an operation amplifier OP and amplified, a set value which is digitized and written is loaded onto a counter to count a time for operating a resonant circuit. The operation time of the resonant circuit can be set by the loaded value of the counter and the oscillation frequency of an oscillator OSC2. Therefore, by varying the resonant circuit operation time in accordance with the load current value and making the value of a current supplied to a switching device constant, after a switching device to be turned off is turned off, the timing when the switching device of the same arm is turned on can be set uniquely. As a result, as the oscillation circuit is not unnecessarily operated, the loss can be minimized.

Title: Relief mechanism for pressure reducing valve
Inventor: OOISHI SHIZUMARO
IPC: G05D16/06
Filed: 1988-06-14
Abstract: PURPOSE:To accurately maintain a secondary side at constant set pressure without any delay by providing a 2nd communication hole which is smaller in diameter than a 1st communication hole which links pressure space with an atmosphere and coupling a pressure adjusting means which adjusts the set pressure to a 1st pressure driven member through a 2nd pressure driven member. CONSTITUTION:If the secondary pressure rises owing to a leak in a valve part, the secondary pressure is accumulated in the pressure space 20 because the hole diameter of the 2nd communication hole 21 is smaller than the hole diameter of the 1st communication hole 19. A 2nd diaphragm 5 positioned on the top surface of the pressure space 20 is large in diameter and pressure reception area than a 1st diaphragm 4, so the 1st diaphragm 4 is further displaced to the opposite side of a stem 12. Then, the spring force of a coil spring 7 is canceled and the extent of the opening between the stem 12 and 1st communication hole 19 is made sufficiently large to release the increased pressure of the secondary side to the atmosphere through the pressure space. Consequently, the secondary side is accurately maintained at the set pressure without any delay.

Abstract: PURPOSE:To realize a high landing tolerance by the minimum variation of pitch by arranging holes on a flat mask so that each line of holes extends parallel to the Y-axis, and so that the pitch of holes which are located at each diagonal end and are parallel to the Y-axis has a specified relation to the pitch of holes located on the Y-axis. CONSTITUTION:Perforating holes 2a on the Y-axis extend from the center (O) of the effective part of a mask, which corresponds to the center of a fluorescent screen, at pitch (ao). Holes 2a on the X-axis are located at every even number rank including the center (O) at pitch 3<1/2>a. The pitches of holes 2a arranged on each line parallel to the Y-axis become gradually smaller as they become apart from the X-axis. Each odd number rank is located in the middle of even number ranks. The holes 2a of each odd number rank extending along the Y-axis are positioned so that the hole number M of each odd number rank corresponds approximately to the mean point of the 4 holes, which are the hole numbers (M) and (M+1) of an even number rank and the hole numbers (M) and (M+1) of the next even number rank. As a result, a high landing tolerance can be realized with the minimum variation of pitch.

Title: Method of injection blow molding wherein planar parison is used
Inventor: SAWADA MITSUO
IPC: B29C51/10
Filed: 1984-07-18
Abstract: PURPOSE:To position a gate mark at a point that will hardly be seen from outside so as to allow the top surface of a product to be made thin, by carrying out injection to make a parison planar. CONSTITUTION:Injection is carried out to make a parison planar. After the injection molding, with the parison being kept heated a movable side mold is moved to clamp a blow mold 1, and when air is supplied from air paths 4, the parison is deformed and extended to come in firm contact with the blow mold 1, on which it is solidified, resulting in a blow molded item 3. As the parison is planar, the position of the gate can be located at an edge section of a product surface that will hardly been seen from outside. As the distance from the parison to the blow cavity surface corresponds to the height of the product, the amount of deformation of the parison becomes uniform relative to the prior method, and the difference of the thickness between the top part and the side part of the molded item can be minimized.
