Abstract: PURPOSE:To obtain a film structure, which is superior in the adhesion between a W film and a poly silicon film, by a method wherein the W film having a high chemical bondability with the poly silicon film is provided on the poly silicon film by a chemical vapor growth method. CONSTITUTION:A gate oxide film 2 is formed on a semiconductor substrate 1 and after a poly silicon film 3 is deposited on the film 2, an impurity is doped in the film 3 and moreover, a natural oxide film on the film 3 is removed by sputter etching. WF6 gas 7 is used as source gas end if the substrate is heated, such a reaction as to be shown by Formula = 2WF6+3Si 2W+3 SiF4 is generated between the WF6 gas 7 and the film 3 and a W film 8 is deposited on the film 3. At this time, the reactivity between the W film 8 and the film 3 is higher than that between a WS12 film deposited by a sputtering method and the film 3 and the adhesion between the W film 8 and the film 3 is very firm.

Title: No-power supply type remote power controller
Inventor: KIMURA YUTAKA
IPC: G06F1/26
Filed: 1990-10-09
Abstract: PURPOSE:To reduce the total cost of a system including an RPC (remote power controller) device and a device to be controlled by generating the necessary electric power from the ringing tone signal received from a telephone exchange and carrying out the detection of the ringing tone signal and the application control of the power supply of the controlled device. CONSTITUTION:When the telephone number of an information processor 1 is transmitted from a center device, a ringing tone CI signal is sent to an RPC device 5 from the exchange of a telephone office. The telephone number is led to a CI detecting part 6 via a noise filter 9 and a DC separating capacitor 8. The part 6 limits the amplitude of the received CI signal to the constant level of voltage by a resistor R1 and a Zener diode DZ1. The limited CI signal is rectified into a direct current by a diode D1 and then smoothed by the resistors R2 and R3 and a capacitor C1. This smoothed DC voltage is stored in the C1 and this stored electric charge is supplied as the necessary electric power of a CI signal detecting circuit and a power controller (incl. a thyristor SR1 and a latch relay 7). Thus the total cost is reduced for a system including the RPC device and the controlled device.

Title: Memory diagnostic circuit
Inventor: NAMIKADO NAGAHIKO
IPC: G06F12/16
Filed: 1989-10-17
Abstract: PURPOSE:To detect an error despite the stop of operation of a circuit set at the write side of a memory circuit by applying a delay overlapping N pieces of parallel input signals to secure the time errors among these signals for execution of a parity operation and transmitting this parity operation result through the memory circuit. CONSTITUTION:N pieces of parallel input signals are delayed by the 1st shift register circuits 1 and 2 by an extent equal to each prescribed number of bits. A parity arithmetic circuit 3 performs the parity operations of both circuits 1 and 2 and stores these arithmetic results in a memory circuit 4. Then N pieces of parallel output signals read out of the circuit 4 are delayed by the 2nd shift register circuits 5 and 6 by the same rule as the input side and undergo the parity operations. A parity error detection circuit 7 compares the parity arithmetic result with the parity signal received from the circuit 4 to decide the presence or absence of an error. Thus it is possible to detect the error of the circuit 4 even if the operation of a circuit set at the write side of the memory 4 is stopped.
