Title: Semiconductor memory
Inventor: MORITA YASUSHIGE
IPC: C21C5/40
Filed: 1990-08-20
Abstract: PURPOSE:To prevent a multi-selection state set and data in a memory cell destroyed and the delay of access occurring by turning on a prescribed I/O switch after turning off all the I/O switches. CONSTITUTION:When an address signal phiA is switched from a first signal to a second signal, a detection circuit 6 detects the change of an address, and generates one-shot pulses phiT, phiTD. A control circuit 7 sets all the I/O switch driving signals phiS1, phiS2 at 'L's while the pulse phiT is set at 'H'. After the 'H' period of the pulse phiT is completed, the signal phiS2 goes to 'H', and the signal phiS1 is held at 'L'. Therefore, only the prescribed I/O switch is turned on after all the I/O switches are turned off when the address designated by the signal phiA is changed and the I/O switches 21, 22 are switched, which prevents the multi-selection state set, and the destruction of the data in the memory cells MC1, MC2 and the delay of access occurring.

Title: Thermal head
Inventor: KATO YOSHIMASA
IPC: B41J2/335
Filed: 1989-08-24
Abstract: PURPOSE:To prevent breakdown of an antiabrasion layer due to electromagnetic breakdown by providing an electroconductive layer in a layer near the surface of the antiabrasion layer. CONSTITUTION:The subject thermal head consists of a TaSiO2 resistor layer 3 and an Al conductor layer 4 applied to a ceramic substrate 1 having a glazed layer 2, which form a thermal resistor pattern part 8 and a conductor connection pattern part. First a 4 mum-thick silicon nitride(Si3N4) is formed on an antiabrasion layer 5D using sputtering technique, then an electroconductive layer 6 for preventing electrostatic breakdown is formed, and a 1 mum-thick antiabrasion layer 5U is formed. Chrominum is sputtered to the electroconductive layer. In this case, if the electroconductive layer is 10 nm or 100 nm, small spots of electrostatic breakdown are recognized in the antiabrasion layer 5u on the electroconductive layer, but no floatation of the antiabrasion layer is recognized. Thus, the reliability of the head is ensured. The thickness of the electroconductive layer is about 10 nm, which is sufficient because an electric charge generated due to increased power supply has only to be released. The electroconductive layer 6 should be carefully positioned because it may completely worn out through long term printing operation if it is too near to the surface, and it may no longer provide protective function against electrostatic breakdown if it is too near to an undercoat.

Title: Voice cell/picture cell reproduction synchronizing device
Inventor: YAGI SHINOBU
IPC: H04L29/12
Filed: 1990-08-20
Abstract: PURPOSE:To synchronously reproduce coded information of voices and pictures at a voice and picture decoding sections, respectively, by applying the readout delay time of a picture cell receiving buffer suitably controlled at every picture frame to the readout delay time of voice cells. CONSTITUTION:A delayed readout section 204 starts the readout of picture cells in a picture cell receiving buffer 113 after readout delay time Td has elapsed from the assembly of the picture cells based on the time stamps marked on the picture cells and the current time indicated by a clock section 123. A voice cell readout controlling section 116 reads out voice sells from a voice cell receiving buffer 114 at regular time intervals T1 after the delay time Td has elapsed from the reception of the 1st voice cell in each voice section. The readout delay time for the 1st voice cell in a voice section is made equal to the readout delay time Td for the picture cells. Therefore, the underflow of the receiving buffers can be prevented even when a cell transfer delay fluctuates in a network.
