Title: Method for diagnosing memory device
Inventor: HIUGA KAZUHIRO
IPC: G11C16/06
Filed: 1999-01-13
Abstract: PROBLEM TO BE SOLVED: To obtain a method for diagnosing the fault of a memory element by referring to a memory address where single-bit error occurrence is recorded and deciding that a control circuit in a memory element has gone out of order, when the memory addresses for single-bit errors generated in a prescribed time are more than a prescribed number. SOLUTION: When the type of the latest error in an error log file is '01', a memory error file is referred to (30). The memory address of the last error log in the memory error file is compared with the memory address of the latest error (40), and when the addresses do not match each other, the current number of memory addresses is compared with a previously set prescribed value (60). When prescribed value is exceeded, it is decided that the control circuit of the memory element is out of order (70) on condition that the generation time difference between the oldest error log and the latest error log in the memory error file is within the previously set prescribed time, thereby outputting an alarm (80). Then all the error logs in the memory error file are erased (90).

Title: Method and device for dry etching
Inventor: NISHIO MIKIO
IPC: H01L21/3065
Filed: 1991-01-25
Abstract: PURPOSE:To provide a method and device for dry etching in which ions do not strike on a wafer and anisotropy can be attained. CONSTITUTION:After generating plasma, an ion is taken out from the plasma and the taken out ion is accelerated to the desired energy by using electric field. The accelerated ion is neutralized without changing the speed by combining an electron from a filament 11, etc., so as to be collided with a subject to be etched (wafer 11). When the neutral molecule (or atom) is collided, the pole surface of the subject to be etched is heated by the kinetic energy possessed by the molecule, the subject reacts to the peripheral etching radical and the etching is proceeded. Since the molecule possessing a direction is used, the same anisotropic etching as a case an ion is used is performed. As the ion does not strike the subject to be etched, electrostatic breakage caused by a charge is prevented.

Title: Protective circuit for input to semiconductor device
Inventor: ARIMA HIDEAKI
IPC: H01L27/04
Filed: 1984-01-18
Abstract: PURPOSE:To obtain an input protective circuit having high withstanding voltage without increasing input capacitance by using polycrystalline silicon as a resistor at the initial step of the protective circuit, forming a diffusion layer being in contact only with a bonding pad and shaping an additional diode. CONSTITUTION:Surge voltage applied to a bonding pad 21 is applied to a polycrystalline silicon layer 22 and a diffusion layer 23, but the peak value of surge lowers because excess currents flow through an silicon substrate 24 through a diode 23a formed by the diffusion layer 23 and the silicon substrate 24. Consequently, even when surge voltage more than the dielectric breakdown voltage of an insulating film 25 under the polycrystalline silicon layer 22 is applied, voltage applied to the polycrystalline silicon layer 22 reduces, and dielectric breakdown is not generated, thus increasing effective surge withstanding voltage. Input capacitance on a viewing from the outside is determined by the capacitance of the diffusion layer 23 at that time, but the capacitance can be reduced when the area of the diffusion layer 23 is selected properly.

Title: Power source device for flash lamp
Inventor: SONE KIYOSHI
IPC: G03B15/05
Filed: 1978-01-26
Abstract: PURPOSE:To reduce charging rush current in a flash lamp power source device for photoreceptor exposure or toner fixing by conducting and energizing a controllable switching element while a main capacitor is charged up to a specified voltage. CONSTITUTION:When the voltage of a capaictor 3 is dropped by discharging through resistances 81 thru 83, the voltage drop of the resistance 83 becomes low and therefore a light emitting diode 8 emits light and a controllable switching element 7 conducts, thus charging a main capacitor 3. Hence, the charging voltage of the main capacitor 3 is maintained at a constant voltage as far as an Ac input AC is being applied. When a discharging trigger switch 5 is closed and a flash lamp 4 discharges and emits light, the controllable switching element 7 conducts and the voltage of the main capacitor 3 rises stepwise. When the AC input AC is cut off, the main capacitor 33 and the capacitors 6C1 thru 612 of a voltage doubler circuit 6 discharge to an earth level. Hence, each capacitor lowers automatically to the earth level at the cut off of AC input.

When the compiler is restarted, the compiler 5 finds a recompilation start position from the editor process information and the table information which is previously held and carries on the compiling process from the position.

Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To eliminate wasteful power consumption and to prevent a magnetic head, etc., from being wastefully used, by unwinding a magnetic tape by forcibly reverse-driving a motor for running the magnetic tape, when a recorded signal is run out in the reproduction process of the magnetic tape. SOLUTION: An output signal of a video IC 30 is inputted, and whether this signal is a synchronized signal or not, i.e., whether the video signal, etc., are being recorded on the magnetic tape 10 or not, is judged. When the output of the video IC 30 is judged as synchronized signal, by means of synchronizing to this signal, the signal to drive for normal rotation of the motor 60 for magnetic tape running is produced and outputted to a motor driving circuit 50. When it is judged as unsynchronized signal, on the other hand, the production of the signal outputting to the motor driving circuit 50 is stopped, while the reproduction of the magnetic tape 10 is discontinued. After that, the signal to drive for reversed rotation of the motor 60 for magnetic tape running is produced and outputted to the motor driving circuit 50.
