Abstract: PROBLEM TO BE SOLVED: To effectively prevent the contact of metal ions in are cording medium with a heating resistor, or the like via pin holes in a protection layer by coating a conductive layer to be applied with a minus potential on the protection layer for coating the heating resistor. SOLUTION: On the upper surface of an insulated substrate 1, a glaze layer 2, a heating resistor 3, an individual electrode 4, a common electrode 5, a protection layer 7, a conductive layer 8, or the like are supported. On the upper surface of the insulated substrate 1 wherein the resistor 3, the individual electrode 4, the common electrode 5, or the like, are mounted, the protection layer 7 is provided so as to cover the resistor 3, or the like. Furthermore, the conductive layer 8 to be applied with a minus potential is provided on the upper surface of the protection layer 7.  Since a minus potential is applied on the conductive layer 8, even when the potential of the individual electrode 4 becomes 0 V while printing, metal ions (Na<+> , K<+> , Mg<2+> , or the like) in the recording medium to be conveyed onto the resistor 3 can be captured securely by the Coulomb's force for dissipate the charge of the metal ions to the outside quickly via the conductive layer 8.

IPC: G11B20/10
Filed: 1998-08-20
Abstract: PROBLEM TO BE SOLVED: To surely detect data on copyright or the like even in the case of compressing data by detecting prescribed data buried in input signals from the coefficient data of plural systems to which an orthogonal transformation is performed. SOLUTION: A decoder 2 detects the data DC of the copyright from digital audio signals DA2. That is, the decoder 2 inputs the digital audio signals DA2 which are time sequential sampling data to fast Fourier transformation circuits 7A-7N and frequency analysis is respectively performed. At the time, the decoder 2 successively delays the digital audio signals which are the sampling data through delay circuits 8B-8NN-1 and inputs them to the fast Fourier transformation circuits 7A-7N. A detector 9 selects prescribed frequency spectrum data from an obtained frequency analyzed result, detects the signal level of the frequency spectrum data and thus, detects and outputs the data DC of the copyright.

Title: Reproducing device of frequency modulated sound signal
Inventor: ITO SHIGEYUKI
IPC: H04N5/94
Filed: 1991-08-22
Abstract: PURPOSE:To prevent FM sound signals to generate pulse noises caused by the malfunction of a drop-out detector during no recording period by not repeating a previous value hold or by shutting out sound signals while pulse noises are continuously generated. CONSTITUTION:When FM sound signals are not being recorded, a malfunction of a drop-out period detector 14 may occur due to noises caused by a recording medium. In that case, a detection is made indicating that drop-outs have continued more than a prescribed frequency by passing a detection pulse (b) through an integrating circuit 15. If a detection signal (e) is inputted to a threshold value circuit 16 which employs an amplitude level E as a threshold value, a detection signal (f) is outputted from the circuit 16. When a previous value holding circuit 11 is operated based on an output signal (g), which is generated by taking an OR of the signals (b) and (f) by an OR circuit 17, the malfunction of the circuit 14 is almost compensated.

IPC: H01L21/60
Filed: 1991-08-21
Abstract: PURPOSE:To prevent crack or peeling on a connecting terminal caused by a stress the due to thermal expansion coefficient. CONSTITUTION:With reference to a semiconductor apparatus in which a silicon pellet 11 is CCB(Controlled Collapse reflow Bonded) on a substrate 21, a protective insulating layer 29 made of a material with a small modulus of transverse elasticity is formed on a base 22 made of an alumina ceramic. Further, longitudinal grooves 33 are formed on the protective insulating layer 29 around the pellet 11. Since the difference of deformation between the substrate 21 and the pellet 11 at the time of thermal variation based on the difference of thermal expansion coefficient between the alumina ceramic and the silicon can be absorbed by plastic deformation of the longitudinal grooves 33 formed on the protective insulating layer 29, a stress of the substrate 21 by the difference of deformation can be controlled. Accordingly, occurrence of crack or peeling on a connecting terminal 34 by CCB can be prevented previously.

Then the level value is compared with a reference value (c) by the microcomputer 8, and when the level value is more than the reference value (c), a change from an information program to a music program is judged and a control code is sent to the DSP 2 to switch the DSP 2 to the OFF state.

Thereafter, the bucket data are read out sequentially to develope them into a bit map tape in a picture drawing control unit 405, then, are developed on a frame buffer 416. When the overflow of the bucket buffer 412 is generated upon setting high resolution mode, the mode is switched into low resolution mode manually or automatically. An area, used for the frame buffer 416, is reduced by switching into the low resolution mode while the unused area is used as the additional area of the bucket buffer 414 whereby printing process is continued.

Title: Integrator arithmetic system
Inventor: FUKUTOMI KOICHI
IPC: G05B19/40
Filed: 1989-09-12
Abstract: PURPOSE:To decrease the necessary number of arithmetic steps by preparing a 1st step where the new preceding value E is obtained from an input A and the preceding value E added together, a 2nd step where the quotient obtained by dividing the new value E by a time constant B is used as an output R, and a 3rd step where the new value E is stored for the operation of the 1st step. CONSTITUTION:An input A is not divided by a time constant B and added to the preceding value E. The result of this addition is used as the new preceding value E for the next operation. Finally the value obtained by dividing the new value E by the constant B is outputted as an output R. An arithmetic error is produced owing to a fact that the fractions are omitted in the division. However the arithmetic error is never produced from the division be cause this division is carried out only when the final arithmetic result is outputted. As a result, the necessary number of arithmetic steps are halved compared with a normal case. Thus the arithmetic time is shortened.
