Title: Semiconductor integrated circuit
Inventor: TANAKA HITOSHI
IPC: H01L27/06
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To obtain a memory macro in which the capacity can be freely varied from small to large capacities and data transfer speed can be accelerated to a high speed and which has little overheads of a circuit by constituting the macro by a plurality of types of modules having different functions in combination. SOLUTION: A memory macro (MMACRO) has functional modules such as an amplifier module (AMP), a bank module (BANK), a power source module (PS) in combination. A row circuit which independently operates and many input/output (O/I) lines extending in bit lines B,/B directions are disposed in the BANK. Thus, since the number of the bank modules can be increased or decreased while remaining the numbers of the input and output lines constant, the capacity can be freely varied from small to large capacities while maintaining the rapidity of the data transfer speed. Further, since the power source and the amplifier can be shared, the overheads of the circuit are reduced.

Title: Sample fixing jig for ic tester using electron beam
Inventor: TOUJIYOU TOORU
IPC: H01L21/683
Filed: 1982-03-31
Abstract: PURPOSE:To permit a sample to be surely fixed onto a sample mount with such a shape as causing no interference on a probe card by a structure wherein a jig for holding the sample is limited in its thickness. CONSTITUTION:A plurality of rollers 31 are attached onto a cassette 30. These rollers 31 are held in position by springs 32 or the like. A wire 34 is stretched among the plural rollers 31 and a wafer is fixed by the wire 34. A stopper 33 and a pin 35 for positioning an orientation flat are also attached onto the cassette 30, but it is enough for them to have a height not greater than 3mm., typically ca. 1mm.. When used, the wire 34 is first stretched. This causes each roller 31 to be retreated via the spring 32, so that the wire 34 comes out of the wafer to permit exchange of wafer. The wafer may be fixed in a reverse manner as compared with the above.

Title: Sheet for printer
Inventor: MUKAI SHIGEO
IPC: B42D5/04
Filed: 1989-03-03
Abstract: PURPOSE:To omit the alignment of a sheet, the work of setting a length in case of outputting by a printer by providing holes indicating the position of a sewing line to be detected by an optical sensor mounted in the printer at a left or right side end separately from feeding holes. CONSTITUTION:Feeding holes 3A, 3B of a tractor are continuously formed at an equal interval at a pair of right and left holes at both ends of a printer sheet 1, and holes 2, 2 indicating a sewing line 4 are formed between the holes 3A. When the sheet 1 is fed, the holes 3A, 3B are detected by optical sensors 20A, 20B of a printer, and the fact that the feeding of the sheet 1 at a predetermined length is confirmed. Since the holes 2 indicating the line 4 is provided only at the right side end, the sensor 20B attached to the other left side end does not detect any when the hole 2 passes the sensor 20A attached to the right side end of the printer. Thus, when the right and left sensors sense differently, the fact that the line 4 of the sheet 1 arrives at a predetermined position can be known.

The longitudinal, flat-join sealed part 121 of the rear part 120 is formed for use as a handhold. In this structure, because the bag is easily made flat by being folded in after use, the bulk of the container can be reduced.

IPC: B01J8/00
Filed: 1986-03-10
Abstract: PURPOSE:To improve the efficiency of mixing and discharging materials by moving a charging and discharging port of a rotary drum to the charging or discharging side of powder and automatically coupling a charging chute or discharging chute to the charging and discharging port. CONSTITUTION:A cap body 22 of the rotary drum 20 is automatically removed and the charging and discharging port 21 of the rotary drum 20 is moved to the powder charging or discharging side at the time of charging and discharging the powder.

Title: Thermostat
Inventor: ISHIO HARUYUKI
IPC: H01H37/38
Filed: 1988-03-04
Abstract: PURPOSE:To facilitate assembly work and to simplify adjustment by assembling such that a 2nd lever comes in contact with a stopper formed by raising a device frame just before a switch is turned on and parts from the stopper just before the switch is turned off. CONSTITUTION:When a switch 39 is turned off, a 2nd lever 33 turns counterclockwise and becomes in a condition apart from a screw 37 provided on a stopper. When a cam shaft 30 is turned to displace a cam arm 31, mainly a 2nd spring 35 displaces while a 1st spring 36 displaces little. However, as the overall force changes, the temperature at which the switch 39 turns off changes. In the case the switch 39 is turned on, a 1st lever 25 turns clockwise, comes in contact with a screw 37 of a stopper 38, and moves up to the point where the switch 39 is turned on. Because a 2nd lever 33 is stopped with a stopper 38, the turning on temperature is determined only by the force of the 1st spring. This temperature remains almost constant regardless of the turning off temperature even if the cam 30 is turned.
