Title: Dust generation prevention device for travel body
Inventor: HOSAI HIROAKI
IPC: B25J19/00
Filed: 1989-10-13
Abstract: PURPOSE:To reduce the suction resistance of a duct part and the capability of a suction device by causing the air in a cover to flow through the duct part with an exhaust fan, and connecting the suction device to a duct. CONSTITUTION:An air flow caused by the first exhaust fan 29 is existing in a cover 24 as shown by an arrow. Dirts generated with the travel of a carrying robot 7, therefore, flow within a duct 27 on the air flow and are drawn into a suction device 32. The dirts are discharged from the device 32 to the outside of a room via the second exhaust hose 33. It follows, therefore, that the dirts generated with the travel of the carrying robot 7 are prevented from being afloat in a clean room 4. Also, the direction of an exhaust generated within the cover 24 due to the first exhaust fan 29 is the same as the suction direction of the device 32 and, therefore, the suction device 32 can be made small correspondingly.

Title: Semiconductor storage device
Inventor: TOKUDA YASUNOBU
IPC: G11C11/409
Filed: 1988-10-21
Abstract: PURPOSE:To shorten the access time by providing an output driver circuit which keeps the potential of an output terminal in the middle level before output of read data. CONSTITUTION:Read data is in the low level when an address signal Ai is in the low level, and read data is in the high level when the signal Ai is in the high level. Since an output pulse ATD of a pulse generating circuit 3 is first in the low level, an output V1 of an output potential detecting circuit 4 is in the low level, and an output V2 is in the high level, and Dout is in the low level in accordance with read data D and the inverse of D. When the signal Ai rises, the pulse ATD goes to the high level, and the output V1 goes to the high level because Dout is in the low level. Then, a P-channel driver 1 is turned on and Dout rises. When Dout reaches the logical threshold voltage of an NOR 6, the output V1 goes to the low level, and the driver 1 is turned off, and Dout stops rising to keep the middle level. When data D and the inverse of D go to the high level and the low level respectively and the pulse ATD goes to the low level thereafter, Dout rises and read data appears in the output terminal. Ai falls to the low level in the same manner.

Patent JP-H08129897-A (JP)
Title: Semiconductor device
Inventor: ISHIKAWA KIMIYASU
IPC: G11C17/18
Filed: 1994-10-28
Abstract: PURPOSE: To obtain an optimum operating characteristic without changing a mask pattern even though an operating power source is changed by performing controls while forming the power source voltage parts of control circuits with N type MOSFETs. CONSTITUTION: When a power source potential VCC is 4V, the potential of a serial connection point N1 and the logical threshold value voltage of a logical sum circuit NOR1 are formed equal. In the case VCC is 5V, the output of NOR2 make an N type MOSFET Q4 nonconductive via an inverter INV2, NOR1 to inactivate a charging circuit CC1. Consequently, the potential of the input junction point COJ of a sense-amplifier SAC connected to a column line is determined by a bias circuit part BC1. Moreover, when VCC is 3V, the output of NOR2 is inputted to one side of NOR1 via INV2 because an inversion signal CEB is a low level. Since the potential of COJ becomes low level because of 3V of VCC, NOR1 outputs a high level to activate CC1. Thus, the input potential of SAC is replenished by CC1 and then SAC continues a normal operation.
