Title: System for totaling device connection time
Inventor: IWAMOTO AKIRA
IPC: G06F13/00
Filed: 1987-03-18
Abstract: PURPOSE:To accurately total connection time by considering a connected device as a connection released one when the time recorded in a log file shows irregular intervals and totaling device connection time. CONSTITUTION:A connection time totaling part 8 examines the interval of the time recorded by a computer system time recording part 7 from recorded contents and totals the connection time by subtracting the connection time from the connection released time of the device as usual if the time shows regular interval. But when the time shows the irregular intervals, the connection time totaling part 8 totals the connection time by considering that the device connected till then is released in terms of connection at that time. Since the loss of the device connection time in case of trouble becomes the interval of the actuation of the computer system time recording part 7 even in case of the maximum, the shorter the interval is, the more accurately the device connection time can be totaled.

Title: Method for driving optical switching element
Inventor: UMEDA TAKAO
IPC: G09G3/36
Filed: 1985-03-29
Abstract: PURPOSE:To prevent decline of optical switching performance and deterioration of element in the driving method of an optical switching element using a ferrodielectric substance, by using AC waveforms as much as possible in the driving waveform of the element. CONSTITUTION:Optical switching sections correspond to the intersecting points of signal electrodes S1-Sn and a common electrode C. When the optical switch of this invention is opened (selected condition), a voltage 2VO is applied across the common electrode C for a period TD only and no voltage is applied during another period TA. When the optical switch is closed (nonselected condition), no voltage is applied during a whole period TS. when such waveforms are impressed, the voltage VF which is applied across the common electrode C and signal electrode S1, namely, across a ferrodielectric substance becomes V51-VC and the time during which a DC voltage is applied can be shortened and an AC voltage can be applied during the remaining period. Accordingly, decline of the optical switching characteristic and DC deterioration of the liquid crystal material resulting from the charge up caused by continuous application of a DC voltage can be prevented.

IPC: H03K19/017
Filed: 1989-03-17
Abstract: PURPOSE:To shorten a data inverting time in a sense amplifier by respectively connecting field effect transistors (TR) in the same type between the respective complementary output terminals of a complementary output circuit and a power source terminal, connecting respective gates to the other output terminals, and restricting the amplitude of a complementary signal. CONSTITUTION:Complementary fine voltages stored through a differential amplifier into a memory are respectively inputted to inputs IN and IN' of a sense amplifier 1. The sense amplifier has a function to amplitude the voltage, connects one of the drain or source of field effect TRs 2 and 3 to respective complementary output terminals 6 and 7, and connects the source or drain of the TRs 2 and 3 to power source terminals 4 and 5.

Abstract: PROBLEM TO BE SOLVED: To obtain a fibrous activated carbon enabling a high molecular material such as humin to be effectively removed even at a high flowing rate of water by forming porous structure having a specific value or more pore diameter and specific surface area. SOLUTION: This fibrous activated carbon has >=24 Å, preferably >=30 Å average pore diameter of the fiber, >=50 m<2> /g, preferably >=500 m<2> /g specific surface area of pores having >=20 Å diameter, and about 10-25 μm fiber diameter. An organic metal compound such as yttrium, titanium and zirconium is mixed with an activated carbon precursor such as a pitch in a solvent. Optionally, the degree of polymerization of the precursor is increased by an air-blowing treatment, and the obtained mixture is spun. A carbonizing treatment and/or an infusible treatment of the spun fiber is carried out and the obtained fiber is subjected to an activating treatment to provide the objective fibrous activated carbon.  The formation of a porous structure is achieved by selecting or combining the organic metal compounds and properly selecting a mixing ratio of the organic metal compound with the precursor. For example, when the activating degree is heightened, pares having large pare diameters are increased, and thereby the specific surface area of the pores having >=20 Å diameters can be set within a prescribed region.
