Title: Fiber channel learning bridge
Inventor: CHAN KURT
IPC: H04L12/56
Filed: 1998-01-22
Abstract: PROBLEM TO BE SOLVED: To simultaneously execute conversation among short or low density loop segments obtained by dividing a long or high density mediation loop by providing a switch means controlled by a memory which stores a transfer table between local and remote fiber channel mediation loops. SOLUTION: A TX port 102 and an RX port 100, which constitute a half bridge, are connected by a local segment return 60, and a memory 78 learns whether the position of a node is local or remote. Thus, the memory 78 stores the positions of respective fiber channel mediation loop (FC-AL) node addresses with the learning. A 20-bit comparator 402 compares the transmission source address of an OPN with a transmission destination address, and simultaneously dissolves an OPN state. All circuits are connected by plural different control signals. Thus, multiple loop segments obtained by dividing FC-AL can simultaneously execute conversation and long waiting times can be avoided.

Filed: 1984-01-26
Abstract: PURPOSE:To obtain a magnetic recording medium having a multilayered magnetic thin film having superior orienting properties and superior surface properties by making the average grain size of a lower layer much smaller than that of an upper layer adjacent to the lower layer. CONSTITUTION:This magnetic recording medium has a magnetic film having high magnetic permeability and low coercive force. The magnetic film contains a magnetic layer 2 having an average grain size A and a magnetic layer 1 adjacent to the layer 2 and having an average grain size B. The layer 1 is closer to the nonmagnetic substrate, and the grain sizes satisfy an equation B<1/2A. The magnetic film is made of an alloy such as ''Permalloy'', ''Alperm'' or ferrite, and Permalloy is suitably used because of its high magnetic permeability. The magnetic film is formed by vapor deposition, sputtering, plating, CVD or other method. When sputtering is applied, the average grain size B of the film is controlled by adjusting the temp. of the substrate, the power of electric discharge or the pressure of gaseous Ar.

Title: Mold coating material for casting
Inventor: NAKADA KUNII
IPC: B22C3/00
Filed: 1980-01-31
Abstract: PURPOSE: To prevent the formation of casting defects such as scabe and sand inclusion by adding and compounding a water-soluble phenolic resin into a mold coating material.  
     CONSTITUTION: When a water-soluble phenolic resin is compounded in the mold coating material, the coating layer has virtually no tendency to soften, shrink and harden even at high temperatures. As a result, the coating material surface remains stable against high temperatures, and does not cause any peeling phenomena, hence it produces no molding defects. Since this material withstands glue molds as well, it is used frequently today. It is also usable for furan resins, CO 2  molds, etc. and prevents casting defects by mold coating materials.

Title: Proportional flow control valve
Inventor: HIRAI MANABU
IPC: F02M69/32
Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To reduce interference between a return spring and an inner diameter of a fixed iron core, reduce hysterisis, and improve accuracy of flow control by increasing an inner diameter of a bottomed hole as an installation part of the return spring of the fixed iron core from a bottom surface toward an opening end. SOLUTION: A return spring 9 arranged between a fixed iron core 2 and a movable iron core 3 is fitted to a bottomed hole on the fixed iron core 2 together with a spring holder 9a. The bottomed hole has a diameter so as to fix the spring holder 9a at its bottom, while its diameter is gradually increased toward an opening end so as to prepare a tapered form. The movable iron core 3 as a valve element is moved by carrying current to an electromagnetic coil 6 for varying an opening of a flow hole 4a formed on a guide cylinder 4. At this time, even when deformation such as variation in an outer diameter or deflection occurs at the return spring 9, its degree of force amount variation is extremely small which may be caused by rubbing between the outer diameter of the return spring 9 and an inner diameter of the bottom hole.  An error of flow control to a current amount of the electromagnetic coil 6 and hysterisis are remarkably reduced.
