Title: Transmitter of pulse width modulation signal
Inventor: HANADA TAKESHI
IPC: H03K9/08
Filed: 1984-06-27
Abstract: PURPOSE:To reduce a ripple included in a demodulation signal without losing the response at demodulation by impressing a compensation signal to an RC filer for demodulation via a photocoupler. CONSTITUTION:A pulse width modulation signal u1 has a duty ratio proportional to an analog signal level desired to be transmitted, is impressed to the RC filter via a differential line driver 2 and photocouplers, 4, 5 and it is demodulated. On the other hand, a pulse width modulation signal having the same period as the modulation signal u1 and 50% of duty ratio when an analog signal is zero, and a compensation signal V1 whose high/low levels are inverted mutually are inputted to the differential line driver 12. The output is received by photocouplers 14, 15, and its output Q1 is impressed to the RC filter. Thus, the ripple included in the demodulation signal is reduced without losing the response at demodulation.

Title: Semiconductor memory
Inventor: TAKASE SATORU
IPC: G11C11/407
Filed: 1992-05-22
Abstract: PURPOSE:To provide a semiconductor memory capable of improving a hit rate and shortening data accessing time. CONSTITUTION:This memory is provided with plural subarrays A and B constituted of a memory area 10 and amplifier groups 14 connected to a bit line BL and for amplifying a signal flowing to this BL line. The amplifier groups 14 are also constituted so as to hold data extracted from rows WL2A and WL1B corresponding to addresses different from each other for each subarray A and B. Thus, the data of rows corresponding to addresses different for subarray A and B from each other are held, and since plural rows are set in a holding state, the probability of hitting accessing demands to the rows in a holding state is improved. Also, since data is held by the amplifier groups, the data is caused to be in an output standby state in the amplifier groups and the data accessing time from the access demands to the output of data is shortened.

Title: Method for laser beam welding galvanized steel sheets
Inventor: ONO MORIAKI
IPC: B23K103/16
Filed: 1992-05-25
Abstract: PURPOSE:To prevent generation of blow holes in lap welding by inserting a thin organic insert material between galvanized steel sheets and welding them with a laser beam. CONSTITUTION:In a process where a laser beam 10 arrives at the insert material 11, first, the resin of the insert material 11 is melted and vaporized at a temperature lower than zinc of the galvanized layers 3, 4 of the galvanized steel sheets 1, 2. Then, when zinc is vaporized, part of carbon in the resin enters a molten pool like the arrows (a), on one hand, since part of zinc vapor from the galvanized layers 3,4 enters a clearance made by vaporization of the resin like the arrows (b), zinc vapor entering the molten pool decreases. Since the viscosity of molten steel containing a small amount of carbon is lowered, zinc vapor is easy to get away from the surface and is scarecely closed in the molten steel. Consequently, a good bead nearly free of generation of blow holes can be obtained.
