Abstract: PURPOSE:To prevent exfoliation of a semiconductor thin film forming a gate electrode, without an increase in the resistance of the gate electrode, by a method wherein the lower layer part of the semiconductor thin film of the gate electrode is made to contain oxygen. CONSTITUTION:A gate electrode 12 of which the lower layer is constructed of a semiconductor thin film 10 containing oxygen and of which the upper layer is constructed of a semiconductor thin film 11 not containing the oxygen is formed on a semiconductor substrate 1 with a gate insulation film 3 interposed therebetween. Next, a high-melting metal film 13 covering at least the aforesaid gate electrode 12, a source region 5 and a drain region 6 is formed and then the high-melting metal film 13 is made to be a silicide 14. For instance, the gate electrode 12 constructed of a DOPOS film 10 containing a very small quantity of oxygen and of a DOPOS film 11 not containing the oxygen is formed, the source region 5 and the drain region 6 are then formed, and thereafter a titanium film 13 is formed on the whole surface. When annealing is executed at a temperature of about 800 deg.C subsequently, the part of the titanium film 13 being in contact with silicon is made to be the silicide and thus a titanium silicide film 14 is formed.

Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To provide a printer device capable of speedily transferring data and a status without erasing the data to be transferred even when the data to be transferred to a host device are prepared in any case. SOLUTION: When a status to be communicated to a host device is generated by a mechanical operation such as paper feeding, paper ejection, and cartridge exchange at the time of a printer operation, a printer checks the position of the generated status among those held at present. When the status is the first one, the status is stored in the first storage place. When the status is the second one, the status is stored in the second storage place. When the status is more than the third one, the status stored in the second storage place is deleted while the two storage places are already filled, and the new status is stored in the second storage place. When the transfer of the status whose communication is normally operated is ended, the second status is exchanged with the first status, and the second status us is deleted.

Title: Mold
Inventor: UENO KOICHI
IPC: B29K21/00
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To prevent flashes among a core, a stationary mold, and a movable mold by retaining a core in slightly shiftable relation in an axial direction, and forming a taper contact face inclined relative to the moving direction and mold clamping direction of a core through molding pressure on a contact face of the core, stationery mold and movable mold adjacent to a molding cavity. SOLUTION: With flow of rubber material form the tip end side to the rear end side within a cavity 5, fluidity pressure is exerted on a core 3 so as to compress the core 3 in the axial direction toward a liner 4. By an effect of this pressure, the core 3 is compressed onto the upper mold and lower mold at a taper contact face 30, and it is compressed thereon in contact relation with a large force. Accordingly, the upper mold 1 and lower mold 2 are prevented from be shifted in its location, and rubber material within the cavity 5 is precluded from coming in the taper face 30. Also high smoothness in a mold aligning face between the upper mold 1 and the lower mold 2 and sufficiently high mold clamping pressure can restrain rubber material from coming in a mold aligning face between the upper and lower molds 1, 2.
