Title: Magnetic recorder
Inventor: GOTO HIDEFUMI
IPC: G11B20/12
Filed: 1987-10-28
Abstract: PURPOSE:To obtain the magnetic recorder of suitable large capacity and high reliability as the peripheral device of a computer by recording the list of an alternative block to a read-in-area, which is provided on the head part of a magnetic tape and recording it also to an EOI block whose place is changed every time data are added. CONSTITUTION:When the magnetic tape is charged in the device, the part of the lowered reliability due to the damage of the magnetic tape is read from the read-in-area, which is at the beginning of the magnetic gape, or an EOI (End Of Information) area and controlled. By recording the position of a record unreproducable area to be newly generated and the area position to be alternative of this area again when the magnetic tape is removed from the device, recorded contents are updated. These information are recorded not only to the fixed area on the magnetic tape but also to the EOI area whose position is changed along the using of the tape. Thus, control can be executed so that the important data can not be deleted and the device can be utilized as the data storage device of the computer.

Title: Image forming apparatus
Inventor: IZUMIYA KENJI
IPC: H04N1/23
Filed: 1999-09-24
Abstract: PROBLEM TO BE SOLVED: To obtain an accurate PWM signal when a dot clock for setting the number of pulses of a reference signal to a predetermined number within a predetermined time is formed. SOLUTION: The cycle of a dot clock is slightly increased or decreased to form a signal wherein the number of pulses generated within a predetermined time is set to a predetermined number. That is, by successively selecting a delay signal which is finely changed in phase gradually without changing clock frequency itself within a predetermined time without finely adjusting clock frequency to set the number of pulses to the predetermined number, the number of pulses generated within the predetermined time is matched with the predetermined number. Further, since the start point and completion point of a PWH signal are selected from the delay signal finely changed in the phase of the dot clock gradually, pulse width is accurately set corresponding to image data.  As a result, when a dot clock changed in phase gradually so as to set the number of pulses of a reference signal to a predetermined number within a predetermined time is formed within one integrated circuit without using an external part, an accurate PWM signal can be obtained.

Title: Semiconductor device and its manufacturing method
Inventor: YOSHIDA HIROSHI
IPC: H01L21/3065
Filed: 1996-10-11
Abstract: PROBLEM TO BE SOLVED: To improve electromigration resistance and enable the prevention of increase in connecting hole resistance due to mask misalignment, by forming an upper cover layer, which covers the upper face of an upper wiring section, integrally with a vertical wiring sections. SOLUTION: In a layered wiring a vertical wiring section 39 that connects an upper wiring section 36 with a lower wiring section 32, is integrated with an upper cover layer 38 that covers the upper face of the upper wiring section 36. To be precise, the vertical wiring section 39 penetrates the upper wiring section 36 and is integrated with the upper cover layer 38. Therefore, the vertical wiring section 39 is brought into contact directly with the upper wiring section 36 through a contact hole CH and indirectly with the upper cover 38 through a second barrier metal layer 37. Thus, the contact faces between the vertical wiring section 39 and the upper wiring section 38 is not the opening of a small contact hole as conventional, and has an increased area of contact.  Thereby, increase in resistance and disconnection due to electromigration EM is prevented, and thus the EM resistance at the contact hole is enhanced.

Abstract: PURPOSE:To provide en IIR digital filter device which has a system clock frequency having no reliance on the bit length of a filter coefficient by processing the multiplication and addition operations in a redundant binary expression with use of a partial product generating circuit which generates a partial product of a redundant binary expression and a redundant binary addition tree which adds the partial product to the accumulated value of the product terms including up to the precedent stage. CONSTITUTION:A partial product generating circuit 9 converts a filter coefficient of an expression form of the complement of 2 into the data of a redundant binary expression form and then generates a partial product from a partial product generation code 11, i.e., the output of a multiplication recorder 8. Then a redundant binary addition tree 10 connected to an array which adds together the partial products of a redundant binary expression performs the multiplication based on the 2-bit booth algorithm. Meanwhile the accumulated value held by a register 4 is assigned to one of inputs of the tree 10, and both multiplication and addition operations are carried out at one time. These operations are carried out in the frequency equal to the stage number equivalent to the tap number of a device. In such a constitution, the caused by an addition operation can cover the place of a single digit at most. Thus the addition operating time is fixed regardless of the bit length of a filter coefficient.
