Patent JP-H11275790-A (JP)
Title: Structure of rotor of brushless motor
Inventor: HOSOI KEIICHI
IPC: H02K1/27
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To prevent increase in cogging torque, by forming recessed sections for increasing reluctance in the external surface of a rotor core corresponding to the inner surface of permanent magnets at the center of magnetic poles. SOLUTION: In a rotor 1, an annular permanent magnet 3 is fixed on the external surface of a cylindrical rotor core. The permanent magnet 3 is formed with N and S poles which are directed radially and are so magnetized that magnetc poles adjacent in the circumferential direction may be N and S poles alternately. In the external surface of the rotor core 2, a recessed section 2a for increasing reluctance in a direct-axis magnetic path passing through the center of each magnetic pole is so formed as to correspond to the inner surface of the permanent at the center of each magnetic pole. Due to the existence of the recessed sections 2a, reluctance is the direct-axis magnetic path of the permanent magnet 3 is increased.  As a result, reluctance at the center of the permanent magnet increases when the permanent magnet 3 of the rotor 1 crosses teeth of a stator during rotation, thereby decreasing attraction between the teeth and the permanent magnet 3 and decreasing cogging torque.

IPC: G06F17/50
Filed: 1998-04-07
Abstract: PROBLEM TO BE SOLVED: To simulate a current flowing in an electronic equipment by means of radiated radio waves of an antenna at high speed by calculating a current flowing in the electronic equipment by due to radiated radio waves of the antenna by solving the simultaneous equations of the moment method having mutual impedance. SOLUTION: Structure information on the electronic unit of a simulation object is read from an electronic unit structure data file 2 and the electronic equipment and an antenna used for simulation are divided into elements. A first calculation means 10 sets a representative frequency on the carrier frequency/upper side band frequency/lower side band frequency of the radio waves which the antenna radiates and calculates the mutual impedance of elements in the representative frequency. A second calculation means 12 solves the simultaneous equations of the moment method having mutual impedance which the first calculation means 10 calculates and therefore current flowing in the electronic equipment is calculated by the radiated radio wave of the antenna with carrier frequency/upper side band frequency/lower side band frequency as calculation objects.

Title: Controlling method for device
Inventor: TANAKA KUNIHISA
IPC: H04Q9/14
Filed: 1981-06-18
Abstract: PURPOSE:To prevent malfunction by constituting a control data of a binary pulse code not similar to a bit code, when a high level pulse of the most significant bit is distorted. CONSTITUTION:Commands for stop, low speed, medium speed and high speed for motor speed control are made by using control signals of CH3,CH7,CH11 and CH19. A signal of MUTE is assigned to the switching of a lighting equipment. Thus, even if a receiver receives said control signals near the distance of limit for remote operation and the control signal MUTE is subject to similar code waveform to code waveform of the control signal CH6 or CH2 because of waveform distortion, and since the CH6 and CH2 are not used for the motor speed control as mentioned above, no malfunction of motor can be caused through the switching of the lighting equipment.

IPC: H01S3/03
Filed: 1999-04-01
Abstract: PROBLEM TO BE SOLVED: To make it possible to prolong the life of a laser tube consisting of a rock crystal, a ceramic material or a glass material by a method wherein the material for the laser tube is subjected to doping so that additional light rays are substantially absorbed in the edge region on the side of laser gas in the laser tube. SOLUTION: A stress is generated in the material for a laser tube 1 by local heating of the laser tube 1 and cooling of the laser tube 1 in after the heating and such damage as a craze and a crack is sometimes generated in the laser tube 1. At that time, the craze or the crack is generated not only in the regions, where are located under the lower parts of electrodes 3 on the laser tube 1, of the laser tube 1 but also in any positions on the tube 1. Accordingly, for making a laser gas high-frequency excitation energy in the extent that such a stress as to make the tube 1 break is generated to absorb in the laser tube 1, a doping material is homogeneously charged in the material for the laser tube 1 by making the doping material mix in an SiO2 molten material, for example.  Thereby, the life of the laser tube consisting of a rock crystal, a ceramic material or a glass material can be prolonged.

Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To make residual liquid usable as quick as possible when the residual quantity is reduced by a method wherein the time required for a liquid in a container for reaching the mouth of the container is shortened. SOLUTION: A liquid housing container comprising a container main body 1A having at its upper part a mouth 2A for spouting liquid housed in the container and a separately molded cap 6A for closing the mouth 2A is a container with a liquid reservoir for which a liquid reservoir 3A being in a groove-like shape with its upper part opened and surrounding without being intermittent round the inner circumferential face of the container is formed being integral with the container main body 1A at the inner circumferential wall at the inside of the container. When the container is used, the liquid returning after use to the lower part of the container is partly collected at the liquid reservoir formed at the inner circumferential face of the container.  Therefore, the liquid collected at the liquid reservoir 3A comes quickly to the mouth 2A of the container at the time of next use even though the residual quantity of the liquid is reduced, and a purpose for which the liquid is used is smoothly achieved.

Title: Accelerating slip control method for vehicle
Inventor: INAGAKI TAKAFUMI
IPC: B60T8/172
Filed: 1986-04-23
Abstract: PURPOSE:To start accelerating quickly by terminating a control for a reduction of slip when a condition where the slip of driving wheels is equal to or less than a predetermined value has continued for a predetermined time while the braking oil pressure of the driving wheels is decreased. CONSTITUTION:Signals from an idler wheel speed sensor 49 and a driving wheel speed sensor 48 are inputted into a control circuit 60 for judging as to whether or not a driving wheel speed is equal to or less than a terminating speed when the braking oil pressure of driving wheels is decreased. In this case, the terminating speed represents a value indicating that a slipping condition is dissolved wherein said speed is set at a value lower than a target value set for a reduction of normal slip. And if the same is equal to or less than the terminating speed, counting-up is preformed by a timer wherein the termination of an accelerating slip control is processed after a predetermined time has elapsed. Owing to this constitution, as the accelerating slip control is quickly terminated when the accelerating slip control is not required, acceleration can be instantly effected as desired.
