Abstract: PURPOSE: To increase a torque transmitted to a driving wheel by placing two holding parts passing through a plane including axis lines of two driving wheels so that the holding parts are stretched outside of the areas of the wheels on either side of the wheels 12 or 13. CONSTITUTION: This device is provided with a control device 30 to drive one of two driving wheels 12 and 13 by a driving wheel 16 before halting the wheels 12 and 13. The device 30 has two braking surface holders 33 and can move orthogonally to a plane including the shafts 31 and 32 of the wheels 12 and 13, and is freely guided by an appropriate means. The holder 33 is of a frame- shaped structure and has two flat holding parts 35 and 36, which pass through a plane 34 including the shafts 31 and 32, and each holding part is placed so as to be stretched outside of the areas of the wheels 12 and 13 on either side of the wheel 12 or 13. In this case, the holding parts 35 and 36 are placed so as to be stretched on the side along the front sides of the wheels 12 and 13 facing winding spindles 10 and 11.

Title: Junction ferrite material for magnetic head, and manufacture of magnetic head
Inventor: MATSUNE KIYOMITSU
IPC: C30B33/06
Filed: 1996-07-31
Abstract: PROBLEM TO BE SOLVED: To reduce the amount of use of single crystal ferrite and reduce the number of surfaces to be finished to mirror surfaces, by using a ferrite material in which a single crystal ferrite substrate is sandwiched by polycrystal ferrite substrates and integrated by junction. SOLUTION: The junction ferrite material A for magnetic head is formed of one single crystal ferrite substrate 2 and a couple of polycrystal ferrite substrates 3 sandwiching the above substrate. The single crystal substrate 2 of the junction ferrite material A is cut into a couple of sections to form two junction ferrite core block half bodies Aa, Ab. The cutting surfaces are wrapped and polished by a cylindrical grinder to form the sliding surface like that of the related art. Therefore, one junction ferrite magnetic head can be formed from a junction ferrite material A having one single crystal ferrite substrate 2 at the material cost equal to almost half of the cost in the related art.  Moreover, since it is enough for the polycrystal ferrite substrate 3 that only the surface junctioned to the single crystal ferrite substrate 2 is finished as a mirror surface, the number of surfaces processed to the mirror surface per magnetic head can be reduced to four surfaces from eight surfaces to reduce the manufacturing cost.

Title: Floppy disk controller
Inventor: YADA YOSHIHARU
IPC: G11B19/16
Filed: 1984-10-19
Abstract: PURPOSE:To detect easily the loading/unloading state of a floppy disk, i.e., a memory medium without destructing the data within a medium, by giving the time monitor to the ready and index signals sent from an FDD (floppy disk driver) through a detecting circuit. CONSTITUTION:The ready signal of an FDD4 is set under a read state when a door is closed after a medium is packed. While the index signal is turned into pulse outputs at a fixed interval. When a medium is replaced, a ready signal becomes busy and the index signal is extracted and kept under an index state until it is packed again. A detecting circuit 2 counts the minimum time necessary for replacement of media and gives a report to a CPU1 that the media is replaced in case both busy and index states last long.

In the case of the brush sliding factors K=0.38 and K=0.48, a brush temperature increases as a gas quantity Q decreases when a rotating speed increases with the decrease of the gas quantity Q. On the other hand, when the sliding characteristic factor K of the brush is set to K=0.53, the rotating speed increases as the gas quantity Q decreases and the brush temperature increases with the decrease of the gas quantity, and when the brush temperature reaches A-point and the gas quantity Q is throttled further, the brush temperature rapidly increases to B-point and a shooting spark is generated from the brush so that the temperature is steady at C-point.

Abstract: PURPOSE:To maintain starting raster quality by detecting variation in vertical raster beam diameter owing to the some what change with a lapse of time of a driving circuit and imposing modulation invariably on initial driving condition. CONSTITUTION:A detection part 53 detects all secular changes (as to a vertical beam) of the driving circuit 51 and a panel 52 and they are fed back to the driving circuit 51 through a modulation part 54. This detection part 53 is provided with a photodetecting element 56 almost at the center part of the left-hand side raster beam of an image display screen. The leftmost end beam which is not used normally is used for the raster (where the part encircled with an alternate long dash and short dash line is viewed as an image). Thus, a quantity corresponding to a vertical brightness distribution is outputted when a beam which deflects the raster on the screen downward passes through the end surface of the photodetecting element 56.

Title: Speech recognition device and standard pattern learning method
Inventor: AMANO AKIO
IPC: G10L15/06
Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To realize speech recognition with high accuracy by using a standard pattern capable of reliably accommodating for the variation of voice patterns. SOLUTION: In standard learning processing, the learning of a standard pattern including the standard pattern corresponding to the knowledge of voice pattern variation is performed by using the learning method for conventional standard patterns. A distribution spread of each standard pattern obtained is measured. If the measured distribution spread is larger than the distribution spread of a standard pattern pluralized based on the variation knowledge, the standard pattern is pluralized and controlled so that the distribution spread of individual standard pattern does not become larger than the distribution spread of the pluralized standard pattern based on the knowledge and becomes the standard pattern balanced as a whole. Since the balanced standard pattern which also complies with universal knowledge on the variation of the voice pattern can be formed, speech recognition with high accuracy is made possible.
