Title: Handwritten character recognizer
Inventor: MIURA MASAKI
IPC: G06K9/62
Filed: 1998-12-01
Abstract: PROBLEM TO BE SOLVED: To provide a handwritten character recognizer which has its fast processing speed by calculating the similarity between a dictionary pattern that is most easily mis-recognized and a generated learning pattern group and registering en bloc the learning patterns of specific conditions in a dictionary or updating these patterns. SOLUTION: A learning pattern generation part 34 sends a learning pattern group and an input pattern, e.g. 'U' (cursive form of Japanese syllabary) to a matching part 16 where the similarity is calculated between them. Then the learning pattern group and 'RA' (square form of Japanese syllabary) that is most similar to the dictionary pattern 'U' are sent to the part 16 to calculate the similarity between them. A learning pattern that has the similarity smaller than a prescribed degree to another dictionary pattern and has the largest composition ratio is decided, and the feature data and the dictionary pattern that recognized the learning pattern are transferred to a dictionary register table 46. A dictionary updating part 36 registers the learning pattern that has the largest composition ratio when plural learning patterns are generated from the same dictionary pattern.

Title: Device for restraining head of disk storage apparatus
Inventor: KAWASAKI TETSUJI
IPC: G11B21/02
Filed: 1991-12-25
Abstract: PURPOSE:To facilitate control of a restricting force by a method wherein a restrictor subjected to a magnetic farce is provided separately from a stopper and the magnetic force of the peripheral edge part of a magnetic field of a permanent magnet on the stator side of a voice coil motor is given to the restrictor while it is diffused appropriately. CONSTITUTION:A restrictor 50 is fitted to a fork-shaped end part 4c on the other side of a carriage 4 with a projection 4d interposed and it is positioned in the vicinity of the peripheral edge of a sectoral range of a permanent magnet 31. In other words, the peripheral edge of the restrictor 50 is made to accord with the peripheral edge of the magnet 31 while it is put in a restricted state. The restrictor 50 is made of a round wire of iron, steel or the like, ferrite and a permanent magnet material and the diameter thereof is made so small as to be about 1 to 2mm. As the restrictor 50 gets off from above the magnet 31, in this constitution, a magnetic field weakens and becomes a diffusive one, the sphere of action of a magnetic restricting force becomes narrow and nonuniformity does not occur. In other words, it becomes very easy to control a head 3 to be at a desired position inside a track zone TZ by a voice coil motor 40.

Title: Double row rolling bearing device
Inventor: MAEBOTOKE MAKOTO
IPC: F16C33/66
Filed: 1997-12-12
Abstract: PROBLEM TO BE SOLVED: To improve workability with performance ensured by adopting a portion, in the diameter direction of the end surface of an inner ring formed of an oiling recess groove, as a ringlike projection protruded in an axial direction than the remainder in the diameter direction of the end surface; and forming the oiling recess groove in a condition crossing the ringlike projection part in the diameter direction. SOLUTION: A bank state ringlike projection 19 is formed over the whole periphery of an inner end surface 15a on the inner end part in the diameter direction of the inner end surface 15a of an inner ring 3a, and is adopted as a flat surface 20 having a trapezoidal cross section shape and parallel to the surface 15a at a tip part, thereby facilitating working the ring 3a having an oiling recess groove 17a. That is, a portion forming the groove 17a out of the surface 15a of the ring 3a is the projection 19 smaller in width than the surface 15a, resultantly the groove 17a can be formed by forging work without using a forging device having large capacity in particular. Consequently the distortion of the inside of the ring 3a, following the forming work of the groove 17a, can be suppressed less, and also the cost of a double row rolling bearing device can be reduced.

Title: Air conditioner
Inventor: TSUCHIYA SHIZUO
IPC: B60H1/22
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To prevent abnormal vibration caused by the rotating speed of a compressor and high pressure of a refrigerating cycle by stopping a compressor when the high pressure of a refrigerating cycle is higher than a preset designat ed pressure and the compressor is low rotating speed, and the rotating speed is lower than a preset designated rotating speed. SOLUTION: When the rotating speed of a compressor 21 is influenced by hot water temperature and the high pressure is higher, a coolant compressor 21 becomes loaded condition with low rotation and high torque to cause abnormal vibration. When the high pressure detected by a high pressure sensor 43 is higher than designated pressure, the coolant compressor 21 is stopped, and when lower than designated pressure, it is operated. Thus, the coolant compressor 21 will not become loaded condition with low rotation and high torque so as to prevent abnormal vibration of the coolant compressor 21. At the time of stopping the coolant compressor 21, the control condition of a fan 9 keeps the condition immediately before the coolant compressor 21 is stopped, and thereby the interior of vehicle can be heated even during the compressor stop.
