Title: Manufacture of semiconductor integrated circuit device
Inventor: FURUKAWA HIROKAZU
IPC: H01L27/02
Filed: 1981-09-09
Abstract: PURPOSE:To acquire a semiconductor integrated circuit device which can prevent deterioration of current amplification coefficient in the low current region by once removing the oxide film of a low voltage, low current circuit and by newly allowing an oxide film in the low surface level charge to grow. CONSTITUTION:After the oxide film 9 having a large surface level charge Qss is formed  on the semiconductor base material, the oxide film 9 on the low voltage, small current  circuit A is removed and then the oxide film 9 having a low Qss is newly formed. The  high voltage, large current circuit B is oxidized by the method other than the oxidation by halogen compound. In the case of a low voltage, small current circuit A for  which a drop of current amplification coefficient beta in the low current region becomes  a problem, the oxide film 9' having low Qss using the halogen compound is grown up. Thereby, the current amplification coefficient in the small current region A of the low  voltage, small current circuit can be improved and simultaneously an adverse effect  such as the channel leak of the high voltage, large current circuit B due to the polarization of Cl<-> ion fetched into the oxide film during the oxidation process by the high  electric field can be prevented since the oxide film consisting of the compound other  than the halogen compound is formed on the high voltage, large current circuit B.

IPC: B65D21/08
Filed: 1993-06-14
Abstract: PURPOSE:To provide a container for a photographic processing compsn. which makes the reduction of volume of the container possible after use and maintains the volume without changing by ordinary handling. CONSTITUTION:Bellows parts 16 are provided with ribs 20 continuously in the height direction of a conainer body along the rugged surfaces of the parts. The prescribed or smaller force to shrink the bellows parts 16 is supported by the axial force of the ribs 20. Then, the bellows parts 16 do not shrink even if such force to press a mouth part 12 is inadvertently applied on the bellows parts 16 and, therefore, the liquid filled therein does not jump out of the mouth part 12. The bellows parts are ruptured in the parts of large frame parts 30 and small frame parts 32 when the bellows parts 16 are intentionally crushed by the prescribed or larger force. The volumetric reduction of the container 10 for the photographic processing compsn. is thus possible.

Title: Stay-on lip end beverage can
Inventor: ARIYOSHI KAZUO
IPC: B65D17/32
Filed: 1989-06-06
Abstract: PURPOSE:To force an unstopper part into a can after drinking, so that a sip part and the unstopper part will stay on the can by a method wherein a score with a central break part is provided at one end of the sip part difined by a U-shaped score and the unstopper part smaller and shorter than the sip part is formed. CONSTITUTION:A recess 7 is formed under a tab 6 in a can lid so as to permit the finger to be easily put into the tab 6 and enable even a child to open the can readily. Since a score 3 with a central break part is formed at one end of a sip part 4, this break part of the score is easy to bend but difficult to tear off to prevent the sip part 4 from being removed from a lid 2. After drinking, therefore, the sip part 4 and an unstopper part 5 can be bent easily inside a beverage can 1 affording a disposal convenience to make the sip part 4 and the unstopper part 5 stay on the lid for a safe disposal of empty can. Since the tab 6 and the unstopper part 5 are formed in a straight position is close contact with the lid 2 when a side view thereof is taken, the can structure can be simplified, although to a slight extent, and the upstoppering action will not take place when a force is exerted on the can from above.
