Title: Measuring instrument for fine particle in lubricant
Inventor: SATO YUZO
IPC: G01N15/00
Filed: 1985-06-28
Abstract: PURPOSE:To detect automatically fine solid particles by flowing a lubricant to the gap between a pair of rollers provided in parallel, and detecting the state displacement of rollers which is caused when fine solid particles of the lubricant pass this gap. CONSTITUTION:If fine solid particles 23 whose particle size D is larger than a gap G between a pair of rollers 2 and 3 exist in the lubricant and reach the gap G, they displaces the roller 3 to pass the gap G by the rotatory power in the tangent direction of the roller 2 and the surface friction between rollers 2 and 3. That is, fine particles 23 allows a load to act upon the roller 3 and displaces the roller 3 against the energizing force of a spring 11. A load cell 19 detects the load applied to the roller 3 at this time, and a displacement meter 18 detects the extent of displacement of the roller 3, namely, the extended gap G. Since a speed detector 17 detects the variance of the rotation speed of the roller 3, fine particles 23 are always detected automatically.

Title: Internal gear and molding method thereof
Inventor: MIZUTA MUNEO
IPC: F16H1/28
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of pitching by providing a cylindrical part which has a tooth part in an inner peripheral part and is continuous with an outer peripheral fringe part of a disklike part and making the density of a central part along teeth of the cylindrical part smaller than the density of an end part on one side. SOLUTION: An internal gear 10 is made of, for example, high density sintered steel, and a pinion gear 16 is made of, for example, steel material. The density distribution of a cylindrical part 10A of the gear 10 is rough along teeth of a tooth part 10a, and the density of a central part 10f of the cylindrical part 10A is smaller than the density of a part connected with an outer peripheral fringe part of a disklike part 10B and one end part of the cylindrical part 10A by about 0.1 to 0.2 g/cm. Consequently, the tooth part 10a of the gear 10 which meshes with a tooth part of the gear 16 is easily displaced along a plane orthogonal to the teeth, and the meshing becomes surface contact, even if parallelism of rotary axial lines of the gears 16 and 10 is out of an allowance scope, to prevent the occurrence of pitching in both end parts of the gear 16.

Abstract: PURPOSE:To make it possible to control easily the layer thickness and the impurity concentration of at least one semiconductor layer in a semiconductor device having a multilayer structure by a method wherein, after a thin film to inhibit an epitaxial growth is formed on a prescribed region on the lower semiconductor layer, other semiconductor layers are epitaxially grown in a state that a prescribed region of the thin film is opened. CONSTITUTION:An SiO2 film 2 is formed on the whole region of the upper part of a semi-insulative InP substrate 1 as a thin film to inhibit an epitaxial growth by an ECRPCVD method and a part, which corresponds to a channel region, of the film 2 is opened by reactive ion etching. A low-impurity concentration (N<->) InP layer 3 is epitaxially grown on the substrate 1 at the opened channel region by an MOCVD method. Then, openings are formed in parts of an SiO2 film 4 by reactive ion etching and high-doped (N<+>) InP layers 5 and 6 are epitaxially grown on the layer 3 on source and drain regions by an MOCVD method. Thereby, a semiconductor device, in which the layer thickness and the impurity concentration of a lower semiconductor layer are controlled with good precision, is obtained.

Title: Method and device for centering log
Inventor: NAGAOKA MASAMICHI
IPC: B27L5/02
Filed: 1993-05-20
Abstract: PURPOSE:To rotatingly cut a log with the axis of the log as its center of rotation by a method wherein the axis center line is computed on the basis of the largest inscribed circles at both end parts of a log obtained from the crosssectional profiles, which are detected by turning contact-type detectors pressed against the log at a plurality of positions in the longitudinal direction on the outer periphery of the log. CONSTITUTION:On the extension of both butt ends of a log 1 placed on bearers 2, turning devices 4 are provided through supporting devices 3 so as to be rotatably turned by turning arms 5. At the end of each turning arm 5, a support 6 is attached so as to pivotally support a displacement arm 7, at the tip of which a sensor 8 is attached in order to energize the detector 8 against the outer peripheral surface of the log 1 with a cylinder. By making the turning device 4 a half turn, the outer peripheral profile of the lig 1 is detected with the detectors 8. On the basis of the outer peripheral profiles of both the butt end faces, the crosssectional forms of the butt ends are obtained, resulting in allowing to obtain the axis center line of the maximum right cylinder. Accordingly, at the installation of holding points, holders can be installed at the center of rotation even under the condition that both the ends of the log 1 are eroded, resulting in allowing to rotatingly cut veneer.

Filed: 1983-08-03
Abstract: PURPOSE:To sink noise, prolong life and enhance the efficiency by furnishing a slide wall member, movable, and an accommodation chamber, for accommodating it at the lower bearing member. CONSTITUTION:In case a rotary compressor 1 operates in its full capacity, a slide wall member 14 overwhelms the force of a spring 16 and blocks the front space 20, because a high pressure gas is introduced to a control port 18 via a back pressure pipe. At this time the front face 44 of said slide wall member 14 is put in a condition as in contact with the contact surface 40 of an accommodation chamber 13, and because both the front face 44 and contact surface 40 are in plane, little clearance part is left to the cylinder part 5. Further the accommodation chamber 13 is located at the lower bearing member 4, so that the lubricant 36 stagnating in this accommodation chamber 13 is encapsulated in a recess 15 to serve as a so called oil damper. Thus collision noise at the contact surface 40 is relieved.

Abstract: PROBLEM TO BE SOLVED: To restrain the occurrence of ghost due to development hysteresis and to obtain a copy of image-defect-flee, satisfactory image quality for a long time by causing residual charges in the dielectric layer or resistance layer of a toner carrier to leak electrically, thereby removing them. SOLUTION: A voltage application member 6 is provided downstream from the position where the toner carrier 3 and an image carrier 1 are opposite each other, and upstream from a toner supply member 5. The voltage application member 6 is so arranged as to rotate in contact with the surface of the toner carrier 3, and a specific DC voltage is applied to it from a variable DC power source 30. With the residual charges having in the dielectric layer or resistance layer, the toner carrier 3 rotates in contact with the voltage application member 6. In the part where the toner carrier 3 and voltage application member 6 are in contact with each other, the residual charges in the dielectric layer or voltage application member 6 leak toward the voltage application member 6 and dissipate. Thus, the toner carrier 3 returns to an initial condition.

Title: End feed-type extrusion method and instrument
Inventor: PIITAA EFU KUROOREN
IPC: B29C48/08
Filed: 1993-06-15
Abstract: PURPOSE: To prevent a flow from being dispersed and reduce the nonuniformity of a flow energy loss accompanied by a change in the flow direction by providing a first flow path which creates a flow in the first main direction as a whole and a change in the second main direction for preventing the flow from being dispersed. CONSTITUTION: A second stage brings about a less significant fluid pressure compensation effect than does a first stage. A transfer wall 66 shows a generally non-linear flow from an inner wall 48 to an inner wall 68 and a gradually increasing rate of change when the flow passes from the second stage to the first stage. The degree of a non-linear flow depends upon, e.g. the extent of a pressure drop in the first main direction, the rheological characteristics of a polymer or an extruded synthetic polymer, a difference in the elevations of gaps I, J and the like. The gap 1 of the second stage is substantially a constant flow path section with the second main direction and consequently, the flow passing through the second stage is substantially subjected to a constant change in the flow path section with the second main direction.
