Title: Motor driver
Inventor: ISHII MITSUNORI
IPC: H02P7/03
Filed: 1995-05-25
Abstract: PURPOSE: To switch the rotating direction of a motor by a simple control signal and, further, improve the reliability without adding a circuit detecting the abnormality, a circuit detecting an excessive current, etc., and reduce the cost. CONSTITUTION: When the level of a rotation signal (a) is turned to low from high, the level of the output of a Schmidt trigger inverter 8 immediately decreased and the level of the output of a Schmidt trigger inverter 7 increases with a certain delay time. Then, if the level of the rotation signal (a) increases from low in order to switch the rotating direction of a motor 1, the level of the output of the Schmidt trigger inverter 7 immediately decreases and the level of the output of the Schmidt trigger inverter 8 increases with a certain delay time.  When the rotating direction of the motor 1 is switched; therefore, a period during which all the switching devices 2-5 are turned off is forcibly inserted and the short circuit of the switching device caused by the abnormality can be avoided, so that the reliability can be improved without any additional circuits and the cost can be reduced.

Title: Calculating method for expected value
Inventor: TAKIGUCHI YOSHIMITSU
IPC: G01R31/317
Filed: 1981-08-14
Abstract: PURPOSE:To calculate the expected value of a logical circuit including a loop, by inserting a virtual element into the loop within a logical circuit, counting the changing frequencies of the signal for the virtual element under a calculation process and turning  the expected value of an output into an uncertain value after the signal changing frequency exceeds a prescribed level. CONSTITUTION:The input terminals (a) and (b) are connected to an AND gate G1 and  an NAND gate G2 for a logical circuit including a loop. The logical circuit which delivers an output to an output terminal (d) contains a closed loop of (G1-c-G2-e-G1) for  the internal signal lines (c) and (e). A virtual element alpha is inserted into the course of  the signal line (e) of the loop, and then the allowable value M is decided for the changing frequency of the signal which is transmitted to the element alpha. An input test pattern  is produced through a computer process, etc. The cumulative changing frequencies of  the transmitted signal are counted if the change of signal exists along with the virtual  element to be transmitted. In the case the count value is larger than the value M, the  expected value is set uncertain for the output of the element alpha and at the same time the value of the signal line (f) is set uncertain. Furthermore the expected value of the  output of the element alpha is set uncertain if just one of the inputs of the element alpha has  the uncertain value.

CONSTITUTION:A chuck part 23 is made to standby at a position over a wafer 28 on a hot plate 27 on a heater block 26. The inner surface of the peripheral part of the chuck part 23 is contacted with the upper surface of the periphery of the wafer 28. Then, a housing 11 is lowered. A receiving plate 19 of the bottom surface of the housing is contacted with a flange part 22 of a chuck holder 16. The central part of the chuck part 23 is pushed. The peripheral part of the chuck part is closely contacted with the upper surface of the periphery of the wafer 28.

Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To control delay time with high accuracy by serially connecting a first gate and a second gate and making the difference of second delay time and first delay time shorter than the first delay time. SOLUTION: The ten pieces of gates G1-G10 provided with the delay time td are serially connected. Also, the nine pieces of the gates G11 G19 provided with the delay time 1.1 td, for instance, longer than the delay time of the gates G1-G10 are serially connected. Then, in the case that only a switch SW6 is closed, the delay time is 6×1.1td+4×td=10.6 td. On the other hand, the delay time is turned to 10 td in the case of closing only the switch SW0 and the delay time is turned to 10.1 td in the case of closing only the switch SW1. That is, in this variable delay circuit, the delay time of 10 td-10.9 td is obtained by the unit of 0.1 td. Thus, the variable delay circuit capable of changing the delay time with the high accuracy is obtained.

Title: Material for measuring membrane performance and inspecting leakage
Inventor: SASAJIMA KUNIHIKO
IPC: G01N15/08
Filed: 1983-07-15
Abstract: PURPOSE:To inspect leakage, etc. of an ultrafilter membrane which allows permeation of a low mol.wt. material even if the membrane is normal and a reverse osmosis membrane having a low removal rate of salts by using a high polymer material formed by binding chemically a reactive dye with a colorless water- soluble high polymer material to form a color. CONSTITUTION:A reactive dye is chemically bound with a synthetic water- soluble high polymer such as PVA to form a colored high polymer. Such high polymer is refined and is then used as a material for inspecting the performance and leakage of an ultrafilter membrane, reverse osmosis membrane, etc. Since the reactive dye binds chemically with the functional group of the water soluble high polymer, the resulting product of reaction is a chemically stable colored high polymer which is identifiable by naked eyes as well if said polymer has a specified concn. or above. There is substantially no deviation in the mol.wt. distribution that arises from the reaction and the solubility and the sepn. characteristic by the membrane are the same as those of the high polymer before the reaction.
