Title: Controller for number of revolution of series commutator motor
Inventor: SHINOHARA SHIGERU
IPC: H02P25/10
Filed: 1981-06-01
Abstract: PURPOSE:To inhibit the number of revolution in case of non-load, and to reduce the abrasion of a brush, a bearing, etc. by controlling feed voltage to the DC commutator motor by using a semiconductor control element. CONSTITUTION:The feed voltage to the DC commutator motor 1 is controlled by using the semiconductor control element 4, and the firing angle of the semiconductor control element 4 is controlled by means of a phase control circuit 5 by employing signals corresponding to the field voltage of field winding 2 at that time. As a result, since the field voltage is low and voltage at both ends of a capacitor 8 for smoothing is low when non-load, currents flowing through a light emitting diode 10a are also reduced. Consequently, the quantity of light emitted from the light emitting diode 10a is little, the resistance value of a light receiving element 10b is increased, and time is taken until the charging voltage of a capacitor 12 for controlling phase reaches the breakover voltage of a Diac 13. Accordingly, the firing angle of the semiconductor control element 4 is enlarged, applied voltage to the motor is low and the number of revolution of the motor is inhibited.

Abstract: PURPOSE:To prevent the occurrence of a resonating state, by a method wherein a heavy object is removably locked to a floating structure, and by means of a detecting signal from a wave period sensor, the heavy object is locked when a wave period about coincides with a natural period. CONSTITUTION:A heavy object 5 is disposed to a floating structure 1 such as off-shore restaurants, and a gear is locked to a rack formed on a strut 7, and this causes repetition of integral engagement with the floating structure 1 and disengagement therefrom. The period of waves surging upon the off-shore structure 1 is detected by a sensor 4, and by means of the detecting signal, it is decided by a deciding circuit 8 whether the period of waves is a value being about similar to that of the natural period of the off-shore structure 1, and in response to a decision signal from the circuit 8, the heavy object 5 is engaged and disengaged. When the period of the wave about coincides with the natural period of the structure, the heavy object 5 is integrally locked, and this enables prevention of the occurrence of a resonating state.

Title: Test facilitating circuit
Inventor: SAKAI MAKOTO
IPC: G01R31/28
Filed: 1986-04-14
Abstract: PURPOSE:To enable an efficient testing with limited testing pins, by zoning logical elements built in an LSI into functional blocks with an input/output pin used in common to perform a test divided into functional blocks through a selector. CONSTITUTION:The drawings (a) and (b) show logic systems which operate in the same way viewed from outside and the shaded parts indicate the grouping of logics. In the drawing (b), the internal logics are divided into proper blocks to facilitate a test by conducting it block-wise. On the other hand, in the drawing (a), it is necessary to conduct a test always learning the operation of the logics as a whole. So, logic elements built in an LSI shown in the drawing (a) are zoned into functional blocks with an input/output pin commonly used. With such an arrangement, when a test for a certain functional block is operated normally through a selector, it indicates that paths through which signals pass are connected normally. Such a test is done for all connections between blocks on a block-by-block basis thereby eliminating the need for a test on a total operation basis. This enables the checking for functions of all logics composing the LSI, facilitating a test.

Title: Movement detection device
Inventor: SUGA KAZUYUKI
IPC: H04N5/765
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To improve the movement detection accuracy by synthesizing two sheets of movement detecting interpolation images having the vertical space phases and frequency bands approximate to each other from both odd and even field images and then comparing these two interpolation images with each other. SOLUTION: The image data Y1(0) and Y2(0) which are shifted from each other by 1/4 pixel in the vertical direction and in the same field are generated by the intra-field linear interpolation. Both data Y1(0) and Y2(0) are set at the same position in a frame. Then two sheets of images having the phases and frequency bands equal to each other in the vertical direction are synthesized from both field images, and the absolute value of difference between the data Y1(0) and Y2(0) is calculated. The absolute value is set with adjustment, so that the misdetection of both movements and horizontal edges can be prevented at a time. In order to obtain a frame static image having no blurring from two sheets of field images through the detection of movements, a frame image is synthesized with interpolation by means of only one of both fields at a part that has movements.
