Patent JP-H0942142-A (JP)
Title: Variable displacement hydraulic motor
Inventor: TSURUMI ISAO
IPC: F15B11/04
Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To restrain any wear in a rotary fulcrum shaft part and a swash plate supporter from occurring as aiming at the promotion of advantageousness on a structural aspect by installing a notch part, being situated at the side of a cylinder block to the axial center of a swash plate mounting hole of the swash plate supporter, in this swash plate supporter. SOLUTION: A clearance C of a notch part C is formed between a swash plate body 14c and a swash plate supporter 17 as exsisting in an end at the base end side of a rotary fulcrum shaft part 14d out of both ends in the axial center Y direction of a swash plate mounting hole of the swash plate supporter 17. With this constitution, oil collected in a driving chamber, after being fed to a plunger sliding surface of a swash plate 4 for lubrication, enters into the notch part C, and it is stuck to a peripheral part being exposed from the swash plate mounting hole of the rotary fulcrum shaft 14d.  If so, when the fulcrum shaft 14d is rotated to alter a swash plate angle, the oil goes round to the inside of the swash plate mounting hole, so that it comes to lubricate a gap between the fulcrum shaft 14d and the swash plate supporter 17 in consequence, and thus they are hard to be worn out and, what is more, durability is well improvable. In addition, with a simple structure that is merely installed with the notch part C, the swash plate is thus economically manufacturable.

Filed: 1996-07-19
Abstract: PROBLEM TO BE SOLVED: To prevent defects of pole braces inclining onto the inside-diameter side at the time of their formation on the connection side of a motor and to improve the reliability as well as the productivity, by forming ribs for preventing the terminal pole braces from inclining onto the inside-diameter side at the time of their formation, inside the terminal pole braces. SOLUTION: Terminal pole braces 7d3, 7d1, 7d2 extend on both sides along the circumferential directions of terminals, an ribs 7f extending in the axial directions from the end parts of the extending parts 7e are formed. As a result of this, it becomes possible to reduce the influence of stresses on the terminal pole braces 7d1-7d3 at the time of hardening of the resin. Further, since the ribs 7f are formed approximately into the shape of a triangle, they do not become hindrances at the time of winding coils. Thus, it becomes possible to prevent the generation of defects in the terminal pole braces 7d3, 7d1, 7d2 inclining onto the inside-diameter side at the time of forming them on the connection side of a motor, to raise the reliability, and to improve the productivity as well in the case of connecting the terminals to a printed board.

IPC: H01J31/12
Filed: 1987-07-30
Abstract: PURPOSE:To cause joints of respective blocks to be unnoticeable, at the time of D/A-converting data accumulated in a memory and outputting them to an electron gun, by executing a prescribed operation to the data with an arithmetic circuit and softening the border of a luminance difference between the adjoining blocks.

Here, the arithmetic circuit 3 makes the data of a farthest edge in respective blocks of an image screen 6 into 1/2. An electron beam from a number (k) electron gun allocated to the number (k) block of the image screen 6 is scanned in right and left directions by one picture element more than the number of the picture elements of one blocks of the image screen to be originally scanned, the electron beam is overlapped and the same picture element on an image screen 7 is made to be emitted. Consequently, the emission on the image screen 7 by an electron beam 10 from the two electron guns is added and emitted. Thus, the joints between the blocks can be made unnoticeable.

Title: Processing device for work
Inventor: SEKIYA HIROYUKI
IPC: B23B29/24
Filed: 1991-07-04
Abstract: PURPOSE:To shorten a cycle time for processing of a processing device provided with a turret. CONSTITUTION:A turret on which multiple processing tools for processing a work are provided is moved between a work processing position and a starting position. The turret returns back to the starting position by moving after processing the work at a processing position A. When the tools reach a position where they do not interfere with the work, indexing of the turret is made to index the tool during the I period. The indexing is made during the period that the turret reaches starting position B while decelerating and then accelerates to gain a movement at constant speed. Thus a cycle time for processing is shortened since indexing is made while the turret is moving.

IPC: G06F12/00
Filed: 1988-08-01
Abstract: PURPOSE: To simultaneously access the indexes of plural transactions without generating any error state during the change of index information by limiting access to a node only to reading access to the other simultaneous transaction and removing the access limitation after record data are fetched. CONSTITUTION: The node is scanned from a route node to the bottom node while using a key record section, the access to the node under scanning and the already accessed node excepting for reading is limited to the other simultaneous transaction, a key record is identified in the bottom node, and access to the key record excepting for reading is limited. Next, the access limitation to the scanned node is canceled and after the key record data are fetched, all the access limitation to the key record are canceled. Thus, simultaneous access is allowed and the information, for which the transaction is changed during the change of index tree structure, is not retrieved.

Title: Particle size distribution measuring method for metal inclusion
Inventor: MATSUMURA TAKASHI
IPC: G01N33/20
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To rapidly and accurately measure the particle size distribution of nonmetallic inclusion dispersively existing in metal by calculating the weight of the evaporated inclusion from the concentration and evaporated amount of an element obtained from the intrinsic spectral intensity of the inclusion forming element, and dividing it by the density of the inclusion to convert it to the particle size as the volume of the spherical inclusion. SOLUTION: The spectral beam at each spark discharge between a sample 2 and an opposite electrode 3 is detected by a detector 6, and the spectral beam intensity of Al of nonmetallic inclusion is, for example, measured. The calibration curve of the Al is applied to the photometrically measured spectral beam intensity of the Al to obtain the Al concentration by an arithmetic processor 5, and the evaporated amount of the corresponding discharge is multiplied by it to calculate the weight of the evaporated Al in the inclusion. Then, it is divided by the molecular configuration ratio of the Al in alumina, converted to the weight of the alumina inclusion, further divided by the density as the volume of one spherical inclusion, and then converted to particle size. After all the spark discharges are finished, the converted data are accumulated to obtain the particle size of the Al inclusion.

Title: Device for detecting state around vehicle
Inventor: MIKI NOBUAKI
IPC: G01S17/93
Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To provide a device for detecting the state around a vehicle which can always continuously seize a preceding vehicle. SOLUTION: A device for detecting the state of around a vehicle finds the variation ΔL of the distance to a preceding vehicle based on the past distance to the preceding vehicle detected by means of a distance detector and estimates, the present distance L(t-Δt)+ΔL to the preceding vehicle from the variation ΔL. In addition, the device presumes the position of the preceding vehicle based on road data from the present location of its own vehicle detected by means of a navigation controller and the estimated distance to the preceding vehicle (S26). Then the device adjusts the detecting direction of the distance detector to the presumed position of the preceding vehicle (S28).  Since the device presumes the position of the preceding vehicle and adjusts the detecting direction of the distance detector to the presumed position, the device can measure the distance to the preceding vehicle without losing sight of the preceding vehicle even when the configuration of the road changes complicatedly.
