Abstract: A plasma display having a quartet type pixel structure provides a high grade and excellent picture quality picture and maintains good white balance and excellent intensity levels. The plasma display comprises a reference circuit .phi. for outputting a control signal based on the least significant bit of a digitized green video signal and a timing signal and an arithmetic circuit 8 for performing an arithmetic operation on the output of the reference circuit. As a result of this arrangement, the least significant bit information, that was lost by halving the green signal value to maintain the white balance is incorporated in the halved green signal based on a timing signal, thereby realizing 256 intensity levels without degrading the halftone in the video picture.

Abstract: The invention relates to a high-density DRAM fabrication technique for forming a source/drain contact between word lines in a self-alignment manner, with the offset length between a source region and a drain region of a peripheral transistor maintained at an adequate value. After gate electrodes (i.e. word lines) are formed, a first insulating layer, which is thin enough not to block up space defined between the word lines, is deposited. The source/drain contact is etched as deep as the first insulating layer is thick to form an extraction electrode made of polycrystalline silicon. A second insulating layer is deposited until a spacer thickness (i.e. the sum of the film thickness of the second insulating layer and the film thickness of the first insulating layer) for determining the offset length is obtained.

Abstract: The composition of a resist material is determined so that the film thinning quantity of the resist pattern is increased when the profile of a resist pattern which is formed in advance tends to be a T-top profile as compared with a reference pattern profile but so that the film thinning quantity of the resist pattern is decreased when the profile of the resist pattern which is formed in advance tends to be a round-shoulder profile as compared with the reference pattern profile. After coating a semiconductor substrate at its top with the resist material whose composition is determined as such to thereby form a resist film, the resist film is exposed through a mask. The exposed resist film is developed, whereby a resist pattern is obtained.

The plural system streams are interleaved in group.sub.-- of.sub.-- pictures GOP units data containing at least moving pictures, and reproduction control information containing special reproduction mode information declaring the address of the next data to be reproduced according to the special reproduction mode used. The plural program chain information entries declare the system stream reproduction sequence of a program chain comprising more than one system stream. At least one system stream is shared by plural program chains. The address information of the first reproduction control information and the address information of the last reproduction control information in each system stream are recorded to the program chain information according to the system stream reproduction sequence.

Abstract: When feeding parts (102) to a mounting machine (A) by using a parts feed cassette (B), prior to parts feed, air is preliminarily supplied to the parts feed cassette (B) to put the parts (102) in neat order, and the parts (102) are preliminarily sent up to a final position in a parts feed route (113). Accordingly, if the parts (102) cannot be securely sent up to the parts feed position (114) in the parts feed route (113) by supplying air (1b) only for a specific limited time for feeding parts (102), the parts (102) can be preliminarily sent forward in neat order, and by the supply of air (1b) for parts feed, the parts (102) can be fed quickly, securely, and stably.

Abstract: A mixed material of liquid crystals and resin is dropped on at least one substrate in an amount greater than the amount needed to cover a display area for the LCD panel. The substrate is adhered to another substrate, and excess material is removed to the outside of a display area. The phase-separation of the liquid crystals and resin is carried out by irradiating light while pressure is added to at least one substrate, so that a liquid crystal display panel applied to a liquid crystal display device or a light shutter can be manufactured without applying a complex vacuum device.

Abstract: A thrust plate disposed between an orbiting scroll member and a bearing for receiving a force axially exerted thereon is provided with a protrusion formed on the same plane as the thrust plate and projected radially inward. The bearing has a thrust plate holder comprising a recess to which the protrusion of the thrust plate fits in, by which the thrust plate is prevented from rotating while being able to move smoothly in an axial direction. Abrasion caused by rotation of the thrust plate is thus prevented, as well as abrasion on outer circumferential parts of the thrust plate can be prevented as a result of the thrust plate is capable of slightly shifting for adjustment to follow up any precessional movement of a thrust load.

Abstract: An ultrasonic motor has a vibrating body 3 and a moving body 11 supported by a supporting component 7. A rounded lower end of the supporting component is supported in a tapered dent of a supporting base 10, and therefore when a side pressure is applied, it inclines to the supporting base so as to keep the contact between the vibrating body and moving body stable. As a result, a stable motor rotation is always obtained regardless of side pressure. A lead wire 8 is held between a metal elastic element 1 and supporting component, and is pressed against the elastic element. Hence, the lead wire, through contact with the elastic element, is electrically coupled to the common electrode on the upper surface of a piezoelectric element without soldering and without use of conductive resin.

Abstract: An exhaust gas purifying method, an exhaust gas filter and an exhaust gas filter purifying apparatus reduce the quantity of collected particulates on the outer periphery of the exhaust gas filter and prevent insufficient combustion of particulates during regeneration. The exhaust gas purifying method purifies an exhaust gas by using an exhaust gas filter including a throughhole diaphragm formed into a honey-comb shape in an outer peripheral wall integrally with this outer peripheral wall. A sealing portion is formed on an end portion of a plurality of throughholes partitioned by the throughhole diaphragm, so that the quantity of particulates collected in the throughholes adjacent to the outer peripheral wall and the throughhole diaphragm is reduced as compared with the other portions. The exhaust gas filter has a second sealing portion formed in the throughholes adjacent to the outer peripheral wall and the sealing portion on one end surface of the exhaust gas filter.

Abstract: When an electronic component is picked up at an electronic component feeding part and then positioned and mounted at a predetermined mounting position on a transparent panel, mounting position marks formed at the mounting position on the transparent panel are registered with positioning marks formed on the electronic component, to thereby recognize the relative position from a surface opposite to a surface of the transparent panel where the electronic component is to be mounted, so that the position of the electronic component is corrected based on the result of the recognition before the electronic component is mounted at the predetermined mounting position on the transparent panel.
