Title: Picture data compressing device
Inventor: FUKUDA MIKA
IPC: H04N1/41
Filed: 1987-06-10
Abstract: PURPOSE:To effectively compress a picture by predicting the transformation coefficient of a block designated by the use of the correlation of the transformation coefficient between the respective blocks obtained from picture data from the transformation coefficient of a circumference block and quantizing the difference value between the predicted transformation coefficient and the transformation coefficient of the designated block. CONSTITUTION:A block reading part 12 sequentially reads the picture data of NXN for one block to original picture data 11 to be compressed. This picture data of NXN is transformed to a two dimensional discrete cosine in an orthogonal transforming part 13 to obtain the transformation coefficient 14 of NXN. Then, this transformation coefficient 14 is compared with the predicted transformation coefficient 16 predicted from the transformation coefficient obtained from the circumference block and the difference value is quantized as data in a quantizing part 18. These encoded data is stored in a storing part 19. In such a way, in order to quantize the transformation coefficient after the orthogonal transformation, the required transformation coefficient is predicted from the circumference block transformation coefficient and the difference value is quantized to obtain a high compressibility.

Title: Ladder-type piezoelectric filter
Inventor: OGAWA TATSUO
IPC: H03H9/60
Filed: 1988-06-13
Abstract: PURPOSE:To satisfy the excellent group delay characteristic and the low insertion loss at the same time by setting the Qm of a piezoelectric resonator at a series/parallel branch of an input/output terminal larger than the Qm of the piezoelectric resonator at the intermittent part respectively, at least, 1.5 time. CONSTITUTION:The Qm of piezoelectric resonators S1, S5 and P1, P4 of the input/output terminal of the series/parallel branches is set larger than the Qm of the corresponding piezoelectric resonators S2-S4, P3, P4 at the intermediate position. Then th relation of the Qm of the input/output terminal of the series branch and the parallel branch and the intermediate part is effective when the Qm of the former input/output terminal is 1.5 time the Qm of the latter intermediate part or over. Thus, the group delay characteristic is improved while suppressing the increase in the insertion loss of the filter.

Title: Thin-film magnetic head and its production as well as magnetic recording and reproducing device using the same
Inventor: HASEGAWA HIROYUKI
IPC: G11B5/39
Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To provide a magneto-resistive thin-film magnetic head with which the wear of the head adequately for a helical scan type magnetic recording and reproducing device is less and the influence of uneven wear is less. SOLUTION: A magneto-resistive(MR) element 1 is held by a pair of substrates 12a and 12b via a protective film 2. Material having high wear resistance is used for the substrates 12a and 12b. Nonmagnetic material which is inferior in wear resistance is packed to both sides of the magnetic pole part of the MR element 1. The progression of the wear of the magnetic head may then be minimized by the substrates 12a and 12b. The uneven wear occurs in the magnetic pole of the MR element 1 but a magnetic tape sinks into the unevenly worn magnetic pole part at the time of traveling and, therefore, comes into good contact with the magnetic pole, by which the spacing loss may be lessened.

Abstract: PURPOSE: To accurately put one's seal to paper by equally applying force to the whole of the face of a seal even when the force applied to the seal is not right-angled to paper by making the angle formed by the face of the seal and a holding shaft changeable at least within the specific range in the up and down direction of the face of the seal. CONSTITUTION: A seal mainly consists of a holding shaft 1 and the face 2 of a seal and the face 2 of the seal is bonded to a face-of-seal stand 3 having a part of a revolving connection member. The shaft 1 and the face 2 of the seal are connected in a freely relatively rotatable manner by a spherical ball 5 and the core rod 6 fixed and connected to the ball 5. Since the ball 5 is fitted in the spherical hollow part 4 formed to the face-of-seal stand 3, the face-of-seal stand 3 becomes freely rotatable centering around the ball 5 within a range of 0-45 deg.. By this constitution, even when sealing is applied in such a state that the shaft 1 is inclined with respect to the surface of paper, the face 2 of the seal is rotated so that the entire surface thereof comes into close contact with the surface of paper to obtain a perfect print of a seal.

Filed: 1985-07-02
Abstract: PURPOSE:To set an abnormal number of revolutions accurately by deciding the abnormal number of revolutions with a signal interval deciding circuit and deciding the duration of the abnormal rotation with a signal duration deciding circuit. CONSTITUTION:A hole element 6 of a rotation detector packaged on the inside of a flowmeter 1 produces two pulses for one rotation of an impeller 4.

In other words, it is decided that the number of revolutions, namely, the flow rate is made under a prescribed value with the signal interval deciding circuit 10. Further, when a state that the rotation of the impeller 4 is slow continues, since the integration voltage of an integration circuit 24 is made under the set voltage of a voltage comparison circuit 27, the output of the signal duration deciding circuit 18 is made a high level and a signal 28 is outputted.

Abstract: PURPOSE:To correct speedily the mixing rate of a mixer to a target rate even when the supply amount of a primary-side raw material is small by supplying a secondary-side raw material regardless of the size of the primary-side raw material if the mixing rate of the mixer deviates from the target ratio.
