Title: Structure of rail
Inventor: UEDA OSAMU
IPC: A47B49/00
Filed: 1989-02-23
Abstract: PURPOSE:To make it possible to obtain high executability since a travelling member can be easily mounted independent of the execution of a rail, by a method wherein cut parts for mounting the travelling member are formed on the sidewall of a rail element member, and a cover plate with which the cut parts are covered and the travelling member is prevented from deviating, is removably provided. CONSTITUTION:A plurality of rail element members 4a are connected in longitudinal direction. A rail 4 with a U-shaped or inverse U-shaped section is thereby formed and a movable member is movably and rotatably mounted thereon through a travelling member. Cut parts 3 are formed on a side wall 4b of each of the rail element members 4a, and a cover plate 24 is removably provided for covering these cut parts 23. After the rail element members 4a are connected in the longitudinal direction, the cover plate 24 is removed and the travelling member is mounted from the cut parts 23. In this way, since the travelling member can be easily mounted independent of the execution of the rail 4, higher executability can be obtained as compared with being executed in a state of mounting the travelling member on the rail 4.

Abstract: PURPOSE:To prevent light interference and to obtain an image free from interference fringes by forming an undercoat layer having a rough lusterless surface on a substrate, and laminating a photosensitive layer sensitive to IR rays. CONSTITUTION:An undercoat layer having a rough lusterless surface is formed on a substrate, and on this layer, a photosensitive layer sensitive to IR rays is formed. The undercoat layer is roughened on the surface by blushing the surface or forming an orange peel on the surface. An undercoat layer blushed on all the surface can be obtained by coating the substrate with a coating soln. obtained by dissolving a nylon copolymer in a methanol-butanol mixture and evaporating the solvent in an atm. of 20 deg.C and 70%RH to speed up evaporation, and lowering the temp. of the support to whiten all the surface of the undercoat layer. A photosensitive layer prepared by forming an electrostatic charge generating layer and a charge transfer layer on the blushed undercoat layer can prevent laser beams from causing light interference and an image having interference fringes can be obtained. The use of the undercoat layer having an orange peel on the surface can also prevent interference fringes on an image.

IPC: B23B51/00
Filed: 1982-03-19
Abstract: PURPOSE:To improve the sharpness of a drill and the discharge of chips by removing a chisel part in the center of the drill and forming a cutting edge of large curvature in the center thereof. CONSTITUTION:Torsion grooves 3 are shaved so that boundaries 8 occur and the depth of a rake surface 7 gradually increases from the center to form a large curvature in the central part. Accordingly, near the center where the moving  speed is slow, the chip on the rake surface 7 is drawn up by neighboring chips.  In other words, chips are made to be raised on the boundaries 8 on the rake  grooves and stripped from the rake surfaces. This operation is repeated by turns  to prevent chips in the central part from being welded.

Title: Engine controller
Inventor: FUJITA NAGAHISA
IPC: F02D41/20
Filed: 1988-02-26
Abstract: PURPOSE:To prevent the worsening of drivability due to resonance in a control system preventable by altering a feedback control characteristic in a direction where the resonance is abated when it is so judged that the control system is in a resonance state or a vibration state proximate to the resonance. CONSTITUTION:At a central processing unit 9, an actual throttle position is compared with a target throttle position conformed to an accelerator manipulated vehicle, and a feedback controlled variable based on the differential portion is calculated. Here amplitude and frequency in duty of a current value to be made flowing into a motor 3 is detected, and the judgement of whether it is in a resonance state or not is carried out. In brief, the amplitude is calculated in looking at a peak-to-peak value of the duty, and also the frequency is calculated in looking at a peak-to-peak period, and on the basis of those of amplitude and frequency, resonance is judged by a resonance map. When it is judged to be the resonance, the current value is compensated and the frequency and amplitude of the duty is shifted to a zone where the resonance will not occur. With this constitution, frequency in the resonance is reduced and, what is more, stability in a control system is enhanced.

Filed: 1983-03-17
Abstract: PURPOSE:To obtain a satisfactory extruded molding by a powder extruding method by placing a pad having ductility on the head part of a preform and extruding a powder molding or sintered body from an extruding pressure vessel. CONSTITUTION:The powder molding or sintered body in an extruding pressure vessel 4 is first compressed and compacted by the pressurization to the yield and deformation of the above-described pad 6 and further a part thereof is extruded from a die 3. Flow is then initiated in the powder molding as well and the powder is extruded in the state of having the central part as a top end and sheathing the circumference with the pad material. The sheath thickness decreases on progression of the extrusion but the sheath remains on the surface layer part and the extrudate as if the entire part is put in a container 7 as shown in the figure is obtd. More specifically, the material 6 exhibits the lubricating effect near the die 3 for its ductility, thus permitting easy deformation of the powder molding. The extrusion molding is thus made possible even if the powder molding is not packed in the container 7.
