Title: Molding material for printed wiring and printed wiring board using the same
Inventor: FUNAYAMA MICHIO
IPC: C08L25/04
Filed: 1993-03-23
Abstract: PURPOSE:To improve adhesion to a metal layer and a peel strength without impairing an excellent heat resistance and a high mechanical strength which are inherent by a method wherein a molding material for a printed wiring is constituted of a highly syndiotactic styrene polymer having a polar group. CONSTITUTION:A molding material for a printed wiring is constituted of syndiotactic styrene resin SPS having a polar group, as a component. The melting point of this SPS is 260 to 270 deg.C and it is much more excellent in heat resistance than a usual atactic styrene polymer. A denatured one of this SPS is obtained, for instance, by introduction of the polar group by a copolymerization reaction at the time of polymerization, by introduction of the polar group at the time of stop of a polymerization reaction, by grafting with bipolar groups, etc. The material for the printed wiring obtained by using this denatured SPS is improved greatly in a peel strength without impairing an excellent heat resistance and a high mechanical strength which are inherent in the SPS, and it is given an excellent fire retardance in addition to these characteristics.

Inventor: FUJII KUNIAKI
IPC: H03L7/06
Filed: 1990-03-14
Abstract: PURPOSE:To attain more accurate signal processing by providing a delay circuit having a delay time equivalent to a phase difference between 1st and 2nd signals to a pre-stage of a signal processing circuit to which the 1st signal is led. CONSTITUTION:A synchronizing separator circuit 1 separates a horizontal synchronizing signal HD from an introduced reproduction luminance signal Y and the separated horizontal synchronizing signal HD is led to a PLL circuit 2 as a comparison signal. The PLL circuit 2 compares the phase of a reference signal generated internally with the phase of a comparison signal and outputs a clock WCK including jitter of the comparison signal to a write address counter 3 as a write clock. A delay circuit 10 retards the introduced reproduction luminance signal Y by a prescribed delay time T0 and gives it to a memory 5 via an A/D converter 4. The delay time T0 is set to a time resulting from one regular horizontal period t0 and a response delay time when the PLI circuit 2 generates the write clock WCK from the horizontal synchronizing signal HD.

Title: Image processor
Inventor: YOSHITAKE TOSHIYUKI
IPC: G06F15/16
Filed: 1989-03-16
Abstract: PURPOSE:To speed up an image processing by dividing an image into minimum processing unit blocks, and setting a square cell where respective processors and arranging and assigning square cells periodically as sets of the minimum unit blocks. CONSTITUTION:A partial image distribution part 11 sets the square cell as a set of the minimum unit blocks corresponding to the number of the processors 131, 132..., which are arranged therein; and the square cells are arranged on the image periodically. The blocks that the respective processors process are scattered periodically and equally on the image and close to blocks that other processors perform, so the loads on the respective processors are dispersed almost equally. A redistribution part 12 evaluates loads as to the distributed blocks and corrects the distribution to redistribute a small number of blocks, thereby distributing the loads more equally. Consequently, the image processing of even an image which is not uniform in picture element density is speeded up.

Filed: 1988-03-17
Abstract: PURPOSE:To make the impedance variable and prevent the generation of a noise by leakage flux by installing a heating coil on a disc iron core having a high magnetic permeability which is formed of split sectors form through an insulating liner, and molding said heating coil with an insulating resin. CONSTITUTION:A spirally wound induction heating coil 1 is installed on a disc iron core 11 having a high magnetic permeability such as ferrite core through an electrical insulating liner 12, and molded integrally on a mounting plate 13 with a resin having an insulating property. The iron core 11 is formed of split sectors having a proper size. As the iron core 11 passes the magnetic flux generated by the coil 1 with little leakage thereof, the increase in the effective flux quantity leads to not only an increase in impedance of the coil 1 to reduce the load current, but also a reduction in generation of high frequency noise by leakage flux to prevent a wrong action and trouble to the outside of the current control circuit. By changing the number of split-formed sectors of the iron core 11 and the thickness of the insulating liner 12, the impedance can be properly regulated.
