Abstract: PURPOSE:To prevent the setting of particles and to diffuse Joule heat an also, to measure the concentration of dilute particle, by revolfing a migration cell and optically detecting the concentration of particle. CONSTITUTION:A migration cell is composed of a large cell 3 and a small cell 8 formed the whole body or a part of it by a transparent body.

Next, migration particles are moved from the cell 3 to the cell 8 by opening the shutter 5 and applying a potential difference between electrodes 4 from a power source 9. Joule heat generated by the influence for the migration by setting of particles and transmission of an electric current, is diffused because of continuing a revolution of the migration cell during a migration state. The transmittance is read by a transmittance meter 10 and also, is recorded  on a recorder 11.

Filed: 1985-07-10
Abstract: PURPOSE:To shorten a warming up time and to speed up recording and start of reproduction and to improve operability by detecting the temperature of a magnetic disk plate or the like, and starting cooling when it reaches to a steady temperature. CONSTITUTION:Immediately after a magnetic disk device is activated, since a magnetic disk plate 2 does not reach a steady temperature, the output of a temperature sensor 1 is smaller than a set value. A blower motor control circuit 4 detects that the magnetic disk plate 2 does not reach to the steady temperature and stops a blower motor 5, and then air is not fed to a HDA 3 and the magnetic disk plate 2 is not cooled, so that it reaches the steady temperature faster. When the magnetic disk plate 2 reaches to the steady temperature, the output of the temperature sensor 1 is larger than the set value, so that the blower motor control circuit 4 detects that the magnetic disk plate 2 reaches to the steady temperature and activates the blower motor 5. Thereby, the air is fed to the HDA 3 and the magnetic disk plate 2 is cooled.

Abstract: PURPOSE:To enable grinding by any grindstone if it is electroconductive, by applying between the grindstone and a workpiece an output voltage or current whose wave form is made from that of rectified alternating waves and that of a superposition of alternating waves and pulses. CONSTITUTION:When terminals A, B, Z, C, D, N, S, E, F, J, K are connected to terminals Z, M, L, G, H, V, W, U, T, X, W, waves made from a superposition of a full wave rectification and pulses are outputted.

IPC: G11B5/193
Filed: 1984-07-25
Abstract: PURPOSE:To control the sliding noise generated from the traveling of a tape by forming a magnetic core, positioned on the inlet side of a traveling direction of the tape, of a high-permeability material, and forming a magnetic core, situated on the outlet side, of a low-permeability material. CONSTITUTION:A couple of magnetic cores 11 and 12 consistf, for example, of an Mn-Zn ferrite single crystal. The magnetic core 11, positioned on the inlet side of the traveling direction 8 of a tape, is formed of a high-premeability material, and composed, for example, of 40-53mol% Fe2O3, 17-40mol% MnO, and 15-40mol% ZnO.

Since the permeability of the magnetic core 11 on the inlet side is high, a high output can be secured, and the sliding noise can be controlled, for example, to about 4dB because the permeability of the magnetic core 12 on the outlet side which is in close contact with the tape is low.

Abstract: PURPOSE:To reduce the occurrence of contradiction as to the state of network by informing the state of an entire packet exchange network from a network controller to all packet exchanges so as to allow the packet exchange side to recognize the entire state in a real time. CONSTITUTION:The network controller 2 references a network state table 10 at a prescribed period, generates network state notifying packets 3-1-3-3 and sends them to all packet exchanges 1-1-1-3. On the other hand, a packet exchange, e.g., 1-1 revises its own table 10 depending on state information 7-1-7-3 in receiving the packet 3-1, generates a reply packet 4-1 depending on the present own state and sends the result to the controller 2. Further, the packet exchange compares the information 7-1 representing the its own state in the packet 3-1 with the present its own state, and if there is any difference, the packet exchange generates network state change notice packets 5-1, 5-2 depending on the present its own state and sends the result to other exchanges 1-2, 1-3.
