Title: Controlling method of synchronous motor
Inventor: SAKAMOTO KEIJI
IPC: H02P23/22
Filed: 1984-04-16
Abstract: PURPOSE:To increase the output torque by altering the phase of an instructed current in response to the saturation degree of a differential voltage between a current of each phase of an armature and a current to be flowed to each phase. CONSTITUTION:If a saturation signal Vr of a saturation detector 30 is 0V, the output of a multi-plug-in D/A converter 24 for multiplying the signal or ROM22 by the signal Vr becomes 0V, and outputs a correction phase current RTC' when the signal Vr is the maximum value. The phase current command RTC and a corrected phase current RTC' are added in a phase shifter 27, and outputs as a phase current command RT corrected from the shifter 27. In other words, the command RT corrected in response to the saturation degree becomes leading at 0 to 45 degrees as compared with the conventional phase current command.

Title: Cathode-ray tube device
Inventor: NATSUHARA MASAO
IPC: H01J29/50
Filed: 1982-05-06
Abstract: PURPOSE:To enable good resolutions to be realized over the entire area of a phosphor screen by correcting the configurational distortion of a beam spot caused by an electron beam which is deflected in an uneven deflecting magnetic field. CONSTITUTION:If the sectional shape of an electron beam passing a focusing electrode system 13 is distorted into a horizontally long ellipse as the degree of beam deflection increases, the electron beam is focused by a main lens part 24 more intensely in the horizontal direction than in the vertical direction, so that the electron beam focused weakly in the horizontal direction and intensely in the vertical direction in a deflecting magnetic field according to the increase in the degree of beam deflection as mentioned above is suppressed. As a result, even a beam spot formed by a horizontally intensely deflected electron beam can be caused to have a shape close to a true circle, and the resolutions of the both sides especially as well as the areas on the diagonals of a phosphor screen are increased. Consequently, a very clear playback picture can be realized over the entire area of the phosphor screen.

Title: Gap measuring method
Inventor: KAMATA SATOMI
IPC: G01B11/14
Filed: 1981-05-21
Abstract: PURPOSE:To measure the size of a gap that a moving body has during its movement on the basis of the time when a beam of light with which the moving body is irradiated passes through the gap and the moving speed, by irradiating the moving body with the beam of light. CONSTITUTION:A front and a rear door incorporated in a car body 11 have a gap 22. The body 11 moves on a production line as shown by an arrow and its speed V is calculated on the basis of a difference in time when two beams of light emitted, for example, at certain distance pass through the car body. The  car body is irradiated with spot laser emitted from a laser oscillator to generate  a beam 23 of light. This beam of light is observed through an industrical television camera. The beam of light moves in the opposite direction to the array as  the car body moves and when it enters the gap 22, an image of the beam of  light on a screen disappears, so this time (t) is measured to calculate the size S  of the gap from S=V.t.

Abstract: PURPOSE:To improve detecting accuracy and to prevent leakage resulting from lengthening piping by combinedly providing a pressure sensor element, a temperature sensor and a computing element. CONSTITUTION:Outputs from a pressure sensor element 1 and a temperature sensor 3 are selectively changed over by an analog switch 2, and supplied through a A/D convertor 4 to a computing element 5, which executes computation on the basis of a state function expression for correcting the temperature characteristic of a previously stored 12a element 1 to obtain a real pressure value from the outputs of the sensor 3 and of the element 1.

In addition when the pressure lowering and rising quantities of the element 1 exceeds a set value, an alarm signal is output, and when the said quantities of the element 1 is within a set range, a normal signal is output. This input state is displayed 011 an indicator 14. Thus the installation of a leak tester and of its piping is unnecessary.

Title: Apparatus for measuring thickness of tube
Inventor: KONDO HIROAKI
IPC: G01B17/02
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To improve reliability of measuring a thickness of a tube by applying a plurality of previous time tracking means after abnormal data is removed. SOLUTION: Reflected echoes detected by a pulser receiver 11 are divided into an S echo and a B echo, and a preset strength is amplified. Deciding circuit echo gates 14, 15 for deciding whether the S echo and the B echo fall within a predetermined strength range or not calculate a time difference between the S echo and the B echo from its output. The difference is converted into a thickness by a thickness calculator 16, and the thickness is input as an output 17 to an abnormal data processor 18. If a measured value is out of a predetermined range such as, for example, of a range of 20 to 150% of the thickness of a material to be measured, the processor 18 decides it as a disturbance to cancel the data, and to hold the previous time value. A plurality of trackings are sequentially conducted by a previous time value tracking device 19 according to a predetermined sequence.
