Patent JP-H1151105-A (JP)
Title: Hydraulic buffer
Inventor: NAKADA ETSURO
IPC: F16F9/348
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To prevent insufficient absorption in a high speed region or a low temperature region and generate stable damping force by providing a non-return spring with characteristics which change a deformation amount non-linearly in correspondence to changes of load. SOLUTION: A non-return valve 22 provided in an upper part of a piston part 2 controls an opening amount in a pressure stroke to generate damping force. Two non-return springs 28A, 28B are overlapped back to back on a top face of the non-return valve 22, and loads WS1, WS2 at which each of them starts the deformation are set to WS1<WS2. When a speed increases in the pressure stroke and pressure applied on the non-return valve 22 increases, the lower non-return spring 28A starts its deformation. When load reaches WS2, the deformation of the upper non-return spring 28B also starts to form non-linear characteristics to which the deformation of two upper and lower non-return springs 28A, 28B is added. As a result, pressure drop generated in the non-return valve 22 is relatively reduced so that stable damping force is obtained.

Abstract: PURPOSE:To enable the automatic deposition of a packing, by melting an end face in the state of the position of a magnet inserted into a packing member being set at the specified position, depositing the melted end face with its abutting corresponding to a preset melting allowance. CONSTITUTION:A packing member 101 is held by a packing moving means hand 21, held with its inputting onto packing hold fixing means 17a, 17b, and the melting allowances 66 at the packing member both ends are set in an arrow mark direction. A fin part fixture is then performed by actuating a fin part fixing cylinder 85. The packing member is thus fixed. However, a magnet 2 is not fixed. The maget position detection/alignment is then performed by separating the packing moving means hand 21. A hot plate 4 is then moved between the end faces of a packing member 101 placed opposite each other, the melting is performed in a non-contact state, and a pressurizing joint is performed by the movement in an arrow mark direction by a two directional pressurizing means. A deposition residue is not sticked to a melting means, the need for removing the residue is eliminated, because the deposition is performed with its melting with non-contact to a heating means, also the gas generated with the residue being burnt can be reduced drastically.

Filed: 1993-09-03
Abstract: PURPOSE:To keep time criticality, to make the processing efficient and to reduce the cost by allowing each node to manage a transmission band based on a transmission reservation synchronization data quantity in its own node so as to eliminate the need for a management node. CONSTITUTION:As an example, a node 2a measures a synchronization data quantity in its own node by its measurement section 4a and number of synchronization data and a total octet number in a synchronization data queue 4 and a time required for transmission of all data by the combination of the both are obtained. Then the obtained number is doubled for circulation transmission of synchronization data and the result is stored in a reservation synchronization data quantity notice 3a and sent to other nodes 2b, 2c. Then the synchronization data stored in the synchronization data queue 4 are sent to a LAN 1 toward a destination node. Furthermore, each node discriminates the propriety of the transmission with respect to a desired transmission produced newly based on the reserved synchronization data quantity to secure the transmission band or the suppression of the transmission. Thus, no management is required and problems attended with installation of the management node are avoided.

Title: Magnetic disk substrate
Inventor: NAKAGAWA YOSHIO
IPC: G11B5/73
Filed: 1997-08-18
Abstract: PROBLEM TO BE SOLVED: To prevent adhesion with a head due to a lubricant oil or water and to prevent damages in a magnetic film due to collision by forming fine projections of crystalline glass in a continuous phase of an amorphous glass on the substrate surface with a specified proportion of the area of projections exposed on the surface. SOLUTION: This magnetic disk substrate 1 consists of a composite material (crystallized glass) of an amorphous glass as a continuous phase and a crystalline phase dispersed in the glass phase and has projections of the crystalline glass. The crystallized glass is produced by melting a source material of a combination of alkali metal oxides and alkaline earth metal oxides, forming the molten material into a plate, heat treating the plate top crystallize to obtain 0.01 to 3.0μm average diameter of the grains and 10<2> to 10<6> particles/mm<2> surface density. Further, the area of projections exposed on the surface is controlled to at most 30% of the unit area of the substrate.  Since the crystallized part is made hard and gives chemically stable projections, adhesion of a head due to a lubricant oil or water can be prevented and damages in a magnetic film 3 due to collision with a head can be prevented.
