Title: Ink jet recording head
Inventor: INOUE NANAO
IPC: B41J2/06
Filed: 1988-05-24
Abstract: PURPOSE:To effectively avoid the breakdown of layer insulation, by setting the thickness of the insulating layer positioned between a current supply electrode and an electrostatic induction electrode so as to make the same larger than that of other part. CONSTITUTION:An insulating layer 20 is applied to a heat generating resistor 11 and a current supply electrode 12 and an electrostatic induction electrode 30 is arranged corresponding to the region of the first insulating protective layer 21 so as to be arranged on the first insulating protective layer 21 at the place corresponding to the heat generating resistor 11 but on the extension part 22a of the second insulating protective layer 22 at the place corresponding to an electrode 12 for the supply of a current to the heat generating resistor 11. Therefore, since the insulating layer 20 between the current supply electrode 12 and the electrostatic induction electrode 30 is obtained by laminating the first insulating protective layer 21 and the extension part 22a of the second insulating protective layer 22 and set so as to become thicker than other part, the resistance value of the insulating layer 20 between the current supply electrode 12 and the electrostatic induction electrode 30 becomes large and a pinhole is hardly formed to the part of the corresponding insulating layer 20 because of the increased thickness and the electric leakage due to the pinhole is effectively avoided.

Title: Magnetic head
Inventor: NAKAGAWA SHIROU
IPC: G11B5/127
Filed: 1977-10-20
Abstract: PURPOSE:To record and reproduce in high frequency region at high performance by positioning the open ends of a pair of leg parts of main magnetic pole towards a magnetic recording medium and constituting the auxiliary magnetic pole in a thin plate construction so that the auxiliary magnetic pole may be positioned within an extended plane of the open end of the main magnetic pole leg part. CONSTITUTION:When a recording current flows in a coil 2, a magnetic flux as shown by dotted line is generated, thereby composing a closed magnetic circuit with bottom part 1b - leg part 1a - magnetic tape 4, auxiliary magnetic flux 5 - tape 4 - leg part 1a - bottom part 1b. This magnetic flux creates a residual magnetic flux on tape 4, thus recording with this residual magnetic flux. In the event of reproduction, the residual magnetic flux on the tape 4 creates a magnetic flux in said closed magnetic circuit, and a voltage is induced on the coil 2. The magnetizing direction of tape 4 is in the direction of film thickness thereof. Thus, utilizing the features of the vertical magnetization method, recording and reproduction in high frequency region may be performed at high performance.

Filed: 1990-05-17
Abstract: PURPOSE:To obtain a large echo dissipation quantity in a short time by updating the tap coefficient of a pseudo echo generating means in accordance with a predicted input voice and a residual echo. CONSTITUTION:An echo canceller generates a pseudo echo for approximating an acoustic echo from an input voice by varying the tap coefficient of a filter in a pseudo echo generating means 1 consisting of a filter having plural pieces of taps. Subsequently, by subtracting this pseudo echo from the acoustic echo by an adding means 2, a residual echo is outputted, and by updating the tap coefficient in accordance with the input voice and the residual echo, the residual echo is converged to zero. In such an echo canceller, by providing predicting means 3, 4, the middle value between the value of the present sampling time of the input voice and the residual echo and a value of the sampling time in the future by one sampling period is predicted, and the tap coefficient of the pseudo echo generating means 1 is updated in accordance with these input voice and residual echo.

Title: Blade holding apparatus for inner peripheral blade
Inventor: HONDA KATSUO
IPC: H01L21/304
Filed: 1988-05-23
Abstract: PURPOSE:To prevent the occurrence of meandering unevenness on a blade face, by fitting the direction of an anisotropic part of an inner peripheral blade on the position of a leaf spring on a rotating plate and setting said blade by a required pushing pressure under this condition. CONSTITUTION:A rotating plate 12 is connected with a tension head assembly 14 through leaf springs 16 placed at 90 deg. intervals. As the tension head assembly 14, a blade 32 stands between a tension ring 20 and a top ring 22 and a tension is thereby provided to the blade 32. As rigidity of the tension head assembly 14 is placed in such a way that displacement is possible in accordance with stress, displacement occurs in accordance with the diameter of the tension assembly 14. Therefore, displacement stress caused by blade setting is scarcely loaded on the rotating plate 12 regardless of the tension of the blade 32.
