Patent JP-S5659365-A (JP)
Title: Arithmetic circuit
Inventor: ITOU HISATSUGU
IPC: G06G7/12
Filed: 1979-10-17
Abstract: PURPOSE:To make it possible to execute the multiplication or division of an analog system, by combining a saw tooth wave generating circuit with a mean value circuit. CONSTITUTION:Electric charge of the capacitor 301 is discharged at the rise of a signal applied to the timing control terminal 30, and when the reset circuit 300 for setting its terminal voltage to zero is not a reset state, a current flowing into the capacitor 301 is Y', and therefore the terminal voltage of the capacitor 301, that is to say, voltage of the output terminal 32 rises up with an inclination of Y'/C. In this case, C shows the capacity of the capacitor 301. The output Z of the mean value circuit 4 becomes Z=Y'/2KC. Also, since Y'=Y, Z=Y/2KC holds good after all, and it proves to have been multiplied and divided. The mean value circuit 4 can be formed by use of the low pass filter consisting of a resistor and a capacitor only, or the active filter for which an operation amplifier is used, etc.

Abstract: PURPOSE:To prevent the break of a carrier table and the like and enable the sufficient cooling of wafers by a method wherein an elevating table is provided at the position of stand-by in a movable manner up and down, and the recovery of wafers process-finished on a processing table and the supply of wafers unprocessed are carried out on the elevating table. CONSTITUTION:When one supporter 9 positions at the position WP1 of stand-by, the elevating table 14A rises. Then, the wafer 6 on a carry-in conveyer 11 is chucked by a vacuum chuck arm 13, thus transferred onto the table 14A, and placed thereon, when the table 14A falls, and the wafer 6 is supported by the supporter 9 during the passage of the table through the aperture of the supporter 9. The carrier table 8 moves, the wafer 6 being carried to the position TP of heat treatment, and the other supporter 9 being then positioned at the position WP2 of stand-by. In this heat treatment, the table 14A stopped at the position of rise limit by thrusting up again above below. Accordingly, the wafer is transferred to a delivery conveyer 12.

Abstract: PURPOSE:To automatically change the color of an output image obtained from a document on the way of output by providing the titled device with a setting means for previously setting the switching of the color of an output image from the document positioned on the way of operation out of plural documents successively sent by a document feeder. CONSTITUTION:While discharging a control sheet 41 to a document receiving part 39, the succeeding document is sent to an exposing position. When a color specification signal is received from an ADF control part 52, a copying machine control part 51 selects a developing device for a specified color and changes the succeeding copying color.

Patent JP-S61293015-A (JP)
Title: Level clamping circuit
Inventor: KAWASHIMA SHOICHIRO
IPC: H03K5/08
Filed: 1985-06-20
Abstract: PURPOSE:To output a specific clamp voltage by adding a level shifting element to a level clamping circuit composed of two MOSFETs. CONSTITUTION:The level shifting element 25 raises the source potential of an FET4, so the difference in threshold voltage between FETs4 and 3 is decreased. Therefore, the FETs3 and 4 are nearly equalized in turn-off timing, so a current which flows from an output to a Vss through the FET4 is reduced. Consequently, a clamp voltage outputted when the level clamping circuit is on is maintained even after the circuit turns off. Thus, the difference in off time between the FETs3 and 4 is decreased to output the specific clamp voltage.

Title: Preserving solution for stabilized carriers used for immunity measurement and immunological measurement method employing the carriers preserved with the preserving solution
Inventor: SAKAGUCHI TAKASHI
IPC: G01N33/543
Filed: 1993-06-04
Abstract: PURPOSE:To accurately make immunity measurement even if carriers in which immunity reaction material is stabilized, are preserved for a long time by letting protease inhibitor be contained in preserving solution for stabilized carriers. CONSTITUTION:One kind or more of the protease inhibitor is made to be contained in solution preserving carriers in which material capable of being immunologically reactive to measured material is stabilized. As favourable example of the protease inhibitor, N-ethyl maleimide, ethylene diamine tetraacetic acid and its salt, and phenylmethane sulfonyl fluoride are use. And as ethylene diamine tetraacetate, alkaline metallic salt such as sodium salt is preferable. In this case, it is preferable that the concentration of protease inhibitor is normally in a range of 1mM to 50mM. As a result, even if carriers in which immunity reaction material is stabilized, are preserved for a long time, immunity reaction material on the carrier surface will never be decomposed, so that accurate immunity measurement can be carried out.

Filed: 1986-06-10
Abstract: PURPOSE:To reduce parasite resistance to be induced on a write bus line by providing a write driver circuit for writing data in memory cell for every memory cell array which is divided into plural division. CONSTITUTION:If a signal Din rises at a time t1, the output signal Din' of a circuit 1 rises at a time t2 because of the delay characteristic of inverter I1-I4. Also at the time t2, signals Din'1 and Din'2 that are supplied through the parasite resistance R1, R2 rises gradually. The speed of the rising of the Din'1 and Din'2 are determined by a time constant which is the product of R1, R2 and the capaci tance of the Din'1 and Din'2. The shiftings of the Din'1 and Din'2 from a low level to a high level turn P-channel type MOSFET Q1, Q3 ON, causing N-channel type MOSFET Q2, Q4 turn OFF, consequently, outputs WB1 and WB2 from write driver circuits 2 and 5 rise at a time t3. With the above-mentioned constitu tion, the parasite resistances induced on WB1 and WB2 comes to one tenth or below of the conventional case.
