Title: Disk spacer
Inventor: AOYANAGI TAKAYUKI
IPC: G11B17/038
Filed: 1987-05-29
Abstract: PURPOSE:To facilitate the insertion and to prevent production of dust by providing the same number of notches to avoid projections as number of the projections to a position corresponding to the spindle projections on the alignment plane of the spacer inner circumference in contact with the spindle projections. CONSTITUTION:Notches 5 to avoid the contact with projections 7 of an alignment plane 6 of the spindle 2 are provided to the inner circumferential face 4 being the alignment plane corresponding to the number of projections 7 of the spindle 2. In the case of using the spacer 3A for the magnetic disk device and in inserting the spacer 3A to the spindle 2, the notch 5 of the spacer 3A is matched with the projection 7 of the spindle 2 to allow the spacer 3A to be inserted without being in contact with the alignment plane 6 of the spindle 2. After the insertion, the spacer 3A is driven to match the alignment plane 4 provided adjacently to the notch 5 of the spacer 3A with the projection 7 of the spindle 2. Thus, the insertion of the spacer to the spindle is facilitated and the production of dust at spacer insertion is reduced.

Title: Automatic gain control circuit
Inventor: NAOI TOSHIMICHI
IPC: H03G5/16
Filed: 1993-06-04
Abstract: PURPOSE:To allow a control circuit to cope with a large level fluctuation by providing a loop filter generating a steady-state fluctuation component corresponding to a steady-state fluctuation of an input analog signal level in a pre- stage of an integration device in a feedback loop so as to improve the tracking performance against a steady-state level fluctuation. CONSTITUTION:An analog signal received from an input terminal 10 is inputted to a level calculation means 3 via an A/D converter 2 to calculate an average power of the received signal. Then a logarithmic transformation means 8 transforms the power in a dB and a difference device 4 obtains a difference DELTAm between the signal subjected to dB transformation and a reference level. A loop filter 9 multiplies a constant beta2 by the difference DELTAm and obtains a DELTAM being the sum of an alpha0 being the integration of the result and a beta1XDELTAm. Then an integration device 5 integrates an output DELTAM from the filter 9 and its output Mn is converted into an analog signal by a D/A converter and it is converted into a control signal Gn by a response function (G)7. The gain is controlled by the signal Gn so that an output level of the amplifier 1 is made constant.

Title: Japanese word processor
Inventor: MIKI YOSHIAKI
IPC: G09G5/08
Filed: 1985-06-20
Abstract: PURPOSE:To recover easily a misoperation just with a shift key operation by using a shift key to deliver an indication to a processor independently of a cursor key for cancel of the range designation. CONSTITUTION:A shift key 105 functions to cancel the designation of an editing range to a sentence under editing by shifting a cursor 102. If a deletion mode is set when the cursor 102 is set at a character 'SAKU', for example, the cursor 102 is shifted by a cursor key 104. Thus all areas through which the cursor 102 passed are equal to the designated areas. Here the key 104 is operated together with push of a shift key 105. Thus a processor 103 can shift the cursor 102 only without designating any range. In such a way, a correct range can be designated without releasing the deletion mode even in case the deletion mode is set while the cursor 102 is set at a wrong position.

Filed: 1977-11-11
Abstract: PURPOSE: To reduce noise of a hermetic compressor, by using a hermetic vessel welded with a resonance inhibitor stepping over a node of the vessel's vibration mode and being made of a plate thicker than that of the vessel.  
     CONSTITUTION: The vibration mode of a hermetic vessel 1 can be changed by welding a resonance inhibitor 3 or a resonance inhibiting mechanism 4 formed solidly with an elastic support 1e of the compressor to the vessel so that it steps to a certain degree over a node 2 of even-numbered circumferential vibration modes. In addition, the thickness of the resonance inhibitor 3 or the resonance inhibiting mechanism 4 together with the elastic support 1e is larger than the thickness of the vessel's plate to reduce the amplitude of the vibration. This means that the noise of the fully hermetic compressor can be reduced by inhibiting the resonance of the hermetic vessel 1.

Filed: 1990-05-24
Abstract: PURPOSE:To make it possible to change a visible image under the ordinary temperature by providing a transfer layer comprising a colorant layer wherein an image is colored by heating for a short time and decolored by heating for a long time. CONSTITUTION:A colorant is provided for making it possible to repeat coloring and decoloring reversibly. After a transfer, a coloring by heating for a short time is necessary in order to form a fine visible image. Here, the coloring by the short time heating means that this colored state is maintained still after it is cooled to the ordinary temperature after heating. A decoloring is to be performed also by heating in order to do the decoloring stably and easily. Here, the decoloring by a long time heating means that this decolored state is maintained still after it is cooled to the ordinary temperature after heating. Therefore, the colored colorant maintains its colored state unless the long time heating is done again. Also, the decolored colorant maintains its decolored state unless the short time heating is done again.

Title: Casting method for fiber-reinforced cylinder block stock
Inventor: SAKUMA TAKESHI
IPC: F02F1/00
Filed: 1985-06-21
Abstract: PURPOSE:To prevent the generation of blowholes in a fiber-reinforced cylinder block stock by mounting a cylindrical fiber molding to the outside peripheral surface of a core for forming a cylinder bore and pouring a molten metal into cavities in such a manner that a back pressure is generated. CONSTITUTION:The opening degrees of small-diameter parts 32a, 33a are throttled by closing pins 34, 35 and the preheated cylindrical fiber molding F is mounted to the outside peripheral surface of the core 41 for forming the cylinder bore. The molten metal is successively poured from a runner 17 of a drag 11 via a gate 19 into the 2nd and 1st cavities C2, C1. The gas such as air in the cavities C1, C2 is lifted by the molten metal and is discharged upward from vent holes 32, 33. Since the opening degrees of the small-diameter parts 32, 33a are throttled, the back pressure is generated in the cavities C1, C2 an acts uniformly over the entire molten metal surface, thereby suppressing waving. The back pressure horizontally raises the molten metal surface to prevent the generation of blowholes. The small-diameter parts 32a, 33a are closed by the pins 34, 35 when the molten metal is fully filled into the 3rd, 4th cavities C3, C4. The molten metal is thoroughly solidified under the prescribed pressure, by which the matrix is made denser and stronger.
