Title: Multilayer printed wiring board
Inventor: MOTOGAMI MITSURU
IPC: H05K3/46
Filed: 1989-07-19
Abstract: PURPOSE:To reduce a dielectric loss and to prevent a signal from being weakebed and heat from being generated by a method wherein an interconnection for power-supply use, a fluororesin sheet and an interconnection for signal use are arranged and formed one after another on the surface of a resin-impregnated base material. CONSTITUTION:Copper foils are piled up on both faces of a glass cloth which has been impregnated with a fluororesin; they are heated and pressurized; the glass cloth and the copper foils are bonded and united via fluororesin thin layers. The individual copper-foils are etched to form interconnections of prescribed patterns for power supply use. Then, copper foils are piled up on the individual interconnections for power supply use; they are heated and pressurized; PTFE sheets and the copper foils are bonded to the interconnections for power supply use. After that, the copper foils on both outer surfaces are etched to form inter- connections of prescribed patterns for signal use. Then, through holes are made; the through holes are plated electrolytically; the interconnections for power supply use and the interconnections for signal use are connected by using a copper-plated layer to obtain a multilayer printed wiring board. Since the insulating layers coming into contact with the interconnections for signal use are formed of the fluororesin sheets, a dielectric loss is reduced and this wiring board can be put to practical use sufficiently even in a high-frequency region.

Title: Magnetic disk device
Inventor: KOMI YOSHINORI
IPC: G11B21/10
Filed: 1989-07-20
Abstract: PURPOSE:To prevent the step-out of a servo sector at the time of positioning heads by providing a timing adjustment area between an inner-peripheral-side recording area and an outer-peripheral-side recording area, where the number of the sectors per track differs. CONSTITUTION:(a)X(c) sectors per track are allocated to the outer-peripheral- side recording area A of the magnetic disk 1, (b)X(c) sectors in the inner- peripheral-side recording area B, and the number of the sectors of the greatest common divisor between the number of the sectors in the recording area A and that of the recording area B in the timing adjustment area C. When the heads 2a and 2b move from the recording area A to the recording area B, or in the opposite way, a control circuit 11 causes FF 10 to generate a servo sink signal with a cycle adjusted to the recording area A or the recording area B in the servo sector starting position of the timing adjustment area C. Consequently, the occurrence of the step-out of the servo sector is prevented even if the heads 2a and 2b move from the recording area A to the recording area B, or in the opposite way, and therefore stable servo control can be realized.

IPC: H04Q1/45
Filed: 1993-07-02
Abstract: PURPOSE:To reduce the time by relieving the processing required for preparation of reception of a PB signal or a DP signal. CONSTITUTION:When a subscriber terminal equipment 1 sends a PB signal or a DP signal in a subscriber circuit 2 accommodating the subscriber terminal equipment 1 sending the PB signal or the DP signal, a PB reception section 6 or a DP reception section 7 receives the signal and converts the signal into a numeral signal of one digit and it is informed to a control section 8. The control section 8 discriminates the PB/DP signal system of the subscriber terminal equipment 1 to allow the reception section making discrimination to receive the numeral signal. A flag is added to the numeral signal in one digit and inserted to a time slot allocated in the unit of subscribers and the resulting signal is sent to a common section 3.

IPC: G11B20/10
Filed: 1996-07-18
Abstract: PROBLEM TO BE SOLVED: To enhance recording density against fluctuation of a target point of focus control even when astigmatism takes place in a laser beam by setting an optimum waveform equalizing quantity. SOLUTION: This waveform equalizing method has the following three main steps. The 1st step is to perform in such a way that the target point of focusing the laser beam is changed, and the target points of making a densest repeating signal and a coarsest repeating signal max. respectively in amplitude are measured, and a middle point between these two target points is decided as the focusing target point. The 2nd step is that under the state of focusing this middle point, the waveform equalizing quantity is changed, and a jitter of regenerative signal after equalizing its waveform is measured, and then the equalizing quantity of making the jitter min. is decided as an optimum setting value for the waveform equalization, and is stored.  The 3rd step is that at the time of working the device, the stored optimum setting value for the waveform equalization is read out, and based on the read-out setting value, the waveform equalization is executed.

IPC: G11C11/4096
Filed: 1994-08-12
Abstract: PURPOSE: To achieve a semiconductor memory capable of keeping a sufficient precharge and an equalization time for transmitting data at a high speed. CONSTITUTION: Plural I/O line pair (I/O, the inverse of I/O) connected with corresponding bit line pair (BL, the inverse of BL) are divided into a first group of I/O line pairs transmitting data by a first group of selection signals CSL 0, 2,... and a second group of I/O line pairs transmitting data by a second group of selection signals CSL 1, 3,.... And, while one group of the I/O line pairs is transmitting data, the other group of the I/O line pairs is precharged and equalized. Thus, since data transmission can be performed concurrently with precharge, it is possible to keep a sufficient precharge time to speed up the data transmission.

Abstract: PURPOSE:To obtain a woven mat having specified length by comparing a mat length measured by a metering wheel with a count number of pulse signals expressing the specified length during the weaving of a mat and controlling the rotational speed of a warp drum with a braking mechanism. CONSTITUTION:A brake band 10 fixed at an end to a machine frame (a) is wound on the outer circumference of a brake wheel 9 attached to an end of a shaft 8 of a warp drum 2 of a rush-weaving frame. The other end of the brake band is connected to an arm 11, a weight 14 is suspended from an end of the arm 11 and the arm is made to be rotatable around the pivoting base part 12 to exert the brake action. A metering wheel 15 is contacted to the surface of a mat (g) passing through a feeding roller 16 in the course of weaving operation. The measured length of the mat (g) is compared with the count number of pulse signals outputted at each arbitrary weaving cycle. When the difference exceeds the permissible range, the weight 14 is adjusted to control the braking action of the braking mechanism 7 and change the rotational speed of the warp drum. The woven length of the mat can be adjusted to the specified level by this process.
