Title: Magnetic disk apparatus
Inventor: WAKATSUKI KOSAKU
IPC: G11B21/21
Filed: 1990-11-30
Abstract: PURPOSE:To achieve a high recording density at an apparatus according to a zone bit recording system by a method wherein a prescribed seek angle is set with reference to the radial line of a magnetic disk and a floating gap in a region in which a magnetic-head slider is moved is made constant. CONSTITUTION:A skew angle theta0 is set at 0 deg. when a magnetic head provided on a magnetic head slider is situated at the inside of the innermost track r1 on a magnetic disk 2. When the magnetic head slider 1 is moved to the direction of an outer circumferential region, it is moved to a direction which has been endowed with a seek angle theta. As a result, when a prescribed seek angle theta is set, the skew angle theta0 becomes larger with an increase in the movement amount of the slider 1. As a result, the increase portion of a floating gap due to an increase in a circumferential speed and the decrease portion of a floating gap due to the endowment with the skew angle theta0 are offset. Consequently, the floating gap can be made always constant. Thereby, a high recording density at an apparatus according to a zone bit recording system can be achieved.

Abstract: PURPOSE:To simplify the constitution of the title device by providing a light emitting body and received light quantity detecting sensor on both sides of a grain moving route and calculating the data regarding the quantity of light transmitted through grain detected at prescribed time intervals, and then, discriminating the grade of the grain based on an overall evaluated value. CONSTITUTION:Grain passes between a light emitting body and transmitted light quantity detecting sensor 2 while the grain is moved at a prescribed speed and the quantity of light transmitted through the grain is detected at prescribed time intervals and inputted to an arithmetic device 3. In order to discriminate whether the measured data indicate that the grain is graded or crashed, the device 3 calculates and evaluates the measuring time (t) during which the quantity of light transmitted through the grain is measured, the number TN of measured value abruptly increasing times during the measurement of the quantity of light, the measured value MP when the quantity increased to the maximum, the mean value MKM of all measured values, the ratio PR of the position when the maximum increased value is measured to the whole and calculates an overall evaluated value TV by taking the sum of each evaluated value. Then the means 3 discriminates the grade of the grain by comparing the value TV with a grade reference value inputted from a grade reference inputting means 15. Therefore, the constitution of this device can be simplified.

Filed: 1993-12-27
Abstract: PURPOSE:To provide the ultrasonic diagnostic device changing the setting speed of sound of all elements at the time of changing the set speed of sound and converging the set speed of sound to the optimal value. CONSTITUTION:The ultrasonic diagnostic device is provided with an element 100 for probe, delay section 100, addition section 120, display section 130, delay control section 140, and section 150 changing the set sonic speed. The device gives the initial value of the set sonic speed commonly to each element, and the delay control section gives the initial delay time distribution to the delay section. Then, the change of the set sonic speed of each element is performed. The set sonic speed of each element to get delay time which is give by the delay section to each reception signal of the element is changed by the section changing the set sonic speed. The section changing the set speed of sound changes the coefficient of each function of the orthogonal function system when the value of the sonic speed to be set to each element is developed by the function comprising the orthogonal function system. Thus, the influence on the tomographic image in changing the set sonic speed can easily be confirmed.

Title: Rolling device
Inventor: YOSHIDA KAZUJI
IPC: B65H23/032
Filed: 1993-12-27
Abstract: PURPOSE:To roll a belt-shaped material superiorly with a simple structure without any control by rolling a belt end, which is conveyed askew, in contact with a restriction means provided adjacent to the rolling means. CONSTITUTION:A rolled paper sheet 1 to be conveyed by conveyance rollers 5, 6 is rolled around a spool 71 so that guides 9, 10 are rotated around their fulcrums as respective rotation centers. Because the rolled paper sheet 1 makes contact with the width-direction restriction means 92 of the guide 9, the end in the direction where the rolled paper 1 is skewed due to the movement of the guide 9 is peeled in the direction opposed to the rolling direction. Peeling of the end of the rolled paper 1 makes tension force of the rolled paper 1 almost uniform so as to perform superior rolling without side slippage and rolling slack. The width-direction restriction means 92 of the guide 9 can be mounted vertically to the guide 9, however, inclination toward the inside can produce more accurate peeling.
