Title: Method for manufacturing semiconductor device
Inventor: SUGANO MICHIHIRO
IPC: H01L21/28
Filed: 2000-02-15
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a semiconductor device that can also cope with flattening and contact formation processes, can reduce the resistance of a gate electrode, and can perform fining. SOLUTION: Impurities by the ion implantation at the part of a gate electrode 27 and that at source/drain regions where ions have been implanted before are activated by the RTA technique. Impurities in a polysilicon film 19 are diffused to the side of a silicon substrate 11 from the doped polysilicon film 19 by the solid phase diffusion technique, thus forming a source/drain region 31. A silicide layer 23 of a high melting point metal is selectively grown onto SiN film 29 with an improved uniformity in film thickness is formed by the CVD. A low-voltage SiO2 film 30 with an improved film thickness is formed on it by the CVD, thus burying a groove on the gate electrode that has been subjected to silicide with the SiO2 film 30.

Title: Control method of flat display device
Inventor: IMAMURA YOICHI
IPC: G09G3/296
Filed: 2000-02-16
Abstract: PROBLEM TO BE SOLVED: To prevent a display body from being deteriorated due to DC driving by forcedly stopping the DC driving of liquid crystal(LC) by a signal management and control means in a display body module when the oscillation of a signal transferred from a display control part is stopped. SOLUTION: Since an output Tn of an 'L' level is supplied to the forced display blank control terminals DF-(bar) of respective scanning drivers and signal drivers in a period from the start of supply of logic power supply Vcc up to the 'H' level of outputs T1 to Tn from a logical circuit, an LC display panel 22 is held at a blank display state. When the oscillation of a signal SP is stopped, outputs T1 to Tn from a sequence processing circuit 51 are turned to 'L' levels, a display OFF signal DF-(bar) is turned to '1' level and the panel 22 is forcedly set up to a display OFF mode. Even when the signal SP is stopped by some causes, voltage applied to LC is dropped to zero, so that LC DC driving can be avoided and the deterioration or the like of the LC can be prevented.

Title: Open type small water heater
Inventor: NISHIYAMA TAKAO
IPC: F23N5/24
Filed: 2000-03-13
Abstract: PROBLEM TO BE SOLVED: To effect operation even when the capacity of a battery is lowered at the end of the life of the battery. SOLUTION: A control means 16 is operated through an operation button 22 to drive a geared motor 14 of a cutoff valve 8. Then, an ignition device 12 is operated and a solenoid valve 3 is also operated. Thereafter, a voltage comparator 19 compares a battery voltage obtained by a battery voltage detector 40 with a threshold. When the battery voltage is lower than the threshold, an ignition retrying means 20 is operated and the valve 3 is switched off while the opening operation of the valve 8 and discharging operation of the device 12 are continued. Upon receipt of the signals instructing that the valve 8 has been fully opened, the valve 3 is reoperated for comparison of the battery voltage with the threshold by the comparator 19. When the battery equals to or above the threshold, gas is combusted to continue the driving of a water heater.  Thus, power consumption is dispersed, not converged, and hence the life of the battery is elongated.
