Title: Hard disk drive
Inventor: TANIGUCHI KAYOKO
IPC: G11B21/10
Filed: 1991-05-29
Abstract: PURPOSE:To improve the recording precision and to increase the recording speed by leading diffracted light, which is diffracted by a diffraction grating provided in a member moving, together with a head as one body, out of a casing to eliminate trouble like application of an excess load to the head and the change of the condition of the head between recording and use. CONSTITUTION:Diffracted light diffracted by the diffraction grating 7 provided in a head arm 5 is led to an external optical system 10 of a casing 1 to eliminate trouble like application of an excess load to a head 5A and the condition change between recording and use. An aperture part 1a of the casing 1 is closed with a light-transmissive material 2 to keep the air-tightness, and the state change between servo signal recording and use due to opening/closing of a cover is eliminated. The grating 7 is freely attachable and detachable and can be used many times, and it is unnecessary to provide an optical system 10 for head position detection as the reflex type. Thus, the use except in a clean room is possible, and the cost is reduced, and the recording precision is improved and the recording speed is increased.

Title: Data detection circuit
Inventor: NAKAI HIROSHI
IPC: H04L25/03
Filed: 1987-05-26
Abstract: PURPOSE:To accurately detect inputted logic data, by setting the DC level of the output of a differentiation circuit at the inside of the hysteresis width of a comparator. CONSTITUTION:The DC level of a differential waveform is biased to a reference voltage VS2 that is a middle point between the higher threshold voltage VS3 and the lower threshold voltage VS4 of the comparator 5 by a bias circuit 3. And the comparator 5, when an input exceeds over the higher threshold voltage VS3, outputs a high level to a point D until the input drops less than the lower threshold voltage VS4, and when the input drops less than the lower threshold voltage VS4, it outputs a low level to the point D until the input exceeds the higher threshold voltage VS3. In such a way, it is possible to output an accurate data detecting output in which a DC component and low frequency noise are eliminated from an input signal by the comparator 5.

IPC: F16C33/10
Filed: 1994-05-17
Abstract: PURPOSE:To prevent the leak of a magnetic fluid by providing a magnet on either a fixed member or a rotating member at an open position outside a radial bearing, forming another rotating or fixed member faced thereto out of a magnetic substance and then increasing a axial flux density gradient in space between the magnetic substance and the magnet in a direction opposite to the open position. CONSTITUTION:A center shaft 3 and a radial slide bearing 2 at the open side of a frame are made of a magnetic substance. Also, a radially magnetized annular magnet 30 is laid on the open side edge of the frame outside the bearing 2. Furthermore, a magnetic circuit formed out of the magnet 30, the shaft 3, the bearing 2 and a holding member 40 is used, in order to form an axial flux density gradient in space between the shaft 3 and the magnet 30 into a unidirectional flux density gradient increasing toward a direction opposite to the open side. As a result, the external leakage of a magnetic fluid 14 can be prevented, due to the action of a magnetic force resulting from the unidirectional flux density gradient, even when, for example, the liquid level of the fluid 14 changes under a volumetric change or dispersion due to a change in atmospheric pressure and temperature, or even when the fluid 14 moves toward a leaking direction due to a shock and a centrifugal force.

Abstract: PURPOSE:To obtain the manufacturing method of a semiconductor laser wherein variable range of wavelength is wide and gain characteristics scarcely have wavelength dependency, regarding the manufacturing method of a semiconductor laser device wherein clad layers and an active layer sandwiched by the clad layers are formed on a semiconductor substrate. CONSTITUTION:Mask layers 4 whose width continuously increases along the laser oscillation direction are formed on both sides of an active layer forming region 3 on a semiconductor substrate 2. When compound semiconductor is deposited from above by a vapor epitaxial method, raw material seed of the compound semiconductor to be deposited on the mask layers 4 diffuses in the lateral direction of the mask layers 4, and is deposited on the active layer forming region 3 sandwiched by the mask layers 4. The wider the mask layer 4 becomes, the larger the amount of the compound semiconductor deposited on the active layer forming region 3 becomes. Hence the compound semiconductor layer can be made thick by increasing the growth speed of the compound semiconductor layer along the laser oscillation direction.
