Abstract: PURPOSE:To increase the speed of a press operation and to improve the efficiency thereof by driving the operation of a liquid pressure type double-action press which is provided with the advantages of both hydraulic press and mechanical press by means of power generators for a high-speed double-action hydraulic press. CONSTITUTION:A hydraulic fluid is fed through respective pipings 6a, 6b by the power generator PGA for actuating a piston-like inner ram 2a which is fixed with an inner punch at the top end and the power generator PGB for actuating an annular outer ram 2b which is fixed with an upper die 3 at the top end and is penetrated with the ram 2a through the central part thereof in the stage of press working with the liquid pressure type double-action press having a liquid pressure type slide 2 consisting of said ram 2a and ram 2b. The outer ram 2b descends earlier than the inner ram 2a to close the dies and the ram 2a descends upon stopping of the outer ram to press the material to be worked in the dies and thereafter the inner ram ascends. The press operation is executed at the high speed and high efficiency by such doubleaction press operation.

Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To prevent damage accident of a wafer or a board when the wafer is transferred, by surely detecting whether the wafer exists in a wafer cassette. SOLUTION: A wafer transferring equipment 20 is made to enter a wafer cassette in order to simultaneously vacuum-chuck and carry a plurality of wafers 1 with tweezers 21A-21E. Only one out of electromagnetic valves 24A-24E is opened, and the other electromagnetic valves are closed. Whether a vacuum- chucked wafer exists on one tweezer or not is judged with either one of vacuum sensors 23A and 24E, and practical wafer accommodation data at a predetermined position in a cassette are obtained. The above process is repeated for all tweezers. Previously stored setting wafer accommodation data are compared with practical wafer accommodation data. When both of the data do not coincide with each other, all electromagnetic valves 24A-24E are closed, an alarm is outputted, and carrying operation of the wafer transferring equipment 20 is interrupted.  When both of the data coincide with each other, the wafer 1 is transferred to a boat by operating the wafer transferring equipment 20.

Title: Refresh counter and refresh counting method
Inventor: RI KOSHO
IPC: G11C11/406
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To prevent a useless refresh operation by activating a reset signal with a counter comparator when an executed refresh number reaches a specified number even when this figure is not 2<n> and initializing a count part at this time. SOLUTION: The counter comparator 201 and a counter 203 are equipped. When a 1st refresh instruction is generated, and a refresh instruction signal CBR becomes high, a row refresh corresponding to the address 0 is executed. When the executed row refresh number K reaches a specified number N, a reset signal XSET1 is activated. At this time, the specified number N may not be 2<n> . The refresh number K is counted by the counter 203, and when the reset signal XSET1 is activated, its output signal is initialized. Therefore, even when the number of row addresses are not 2<n> , refreshing is performed by an actual number of addresses without performing useless counting operation, so that the performance at a system level is enhanced.
