IPC: G01R13/22
Filed: 1995-03-24
Abstract: PURPOSE: To obtain a measuring method of an effective value wherein the effective value of an input signal is calculated directly from digital waveform data on the input signal. CONSTITUTION: A measuring method of an effective value of a waveform fetching device which has an analog-digital converter converting an input signal into digital waveform data and a memory storing the digital waveform data. This method is featured by that a period To of a fundamental wave is determined by FFT(fast Fourier transform) computation of the digital waveform data and that the effective value of the input signal is calculated from the digital waveform data corresponding thereto during the period To of the fundamental wave. Only by computation, accordingly, the effective value of the input signal having a distorted waveform or the input signal of nonperiodicity can be measured simply without any change in hardware of the waveform fetching device.

Filed: 1990-04-06
Abstract: PURPOSE:To facilitate lock or the cancel of lock to a tape reel without fail by forming plural projections on a sliding surface with the reel lock member of a cassette case and sliding the reel lock member in the state of contact with the projections. CONSTITUTION:When a tape cassette 1 is loaded to a recording and reproducing device, a reel lock member 11 is moved backward against the force of a coil spring 25 with the movement of a lock cancel pin 2 in an arrow D direction, and engagement between lock pieces 13 and 13' and gears 8 and 8' of lower flanges 7 and 7'. The movement of the reel lock member 11 is executed by sliding the bottom surface of a main part 12 on projecting lines 23 and 23 provided at the cassette case. Therefore, even when there are burrs or burr-shaped projections at the opening edge of an inserting hole 21 or around an abutting track 24 of an eject pin, the reel lock member is smoothly moved without being affected by them at all. Thus, the lock or the lock cancel is executed to tape reels 3 and 4 without fail.

Abstract: PROBLEM TO BE SOLVED: To prevent the level of a steam separator from being lowered owing to the generation of a swelling by providing a delay timer for receiving the output of a set/reset device, receiving a furnace passing flow rate signal after the joint of a boiler water feed line and a furnace recirculating line, resetting and inputting the output. SOLUTION: First high signal detectors 40a to 40c to which the valve opening signals 16as to 16cs of respective level control valves 16a to 16c are inputted send the outputs to an AND element 42 when input values are not lower than a prescribed value. When the AND element 42 simultaneously receives the outputs of a timer 43 and the AND element 42, it sends a set signal to a set/ reset device 46. A second high signal detector 44 to which a furnace passing flow rate signal 26s from a furnace passing flow rate detector 26 is inputted outputs the input when the input value is not lower than a prescribed value. A delay timer 47 receives the output of the set/reset device 46, delays the output by time required for increasing the flow rate of a water feed pump, and outputs the delayed output.  When a second AND element 45 receives these signals at the same time, it sends a reset signal to the set/reset device 46.

IPC: G01R31/28
Filed: 1989-04-12
Abstract: PURPOSE:To notify unchanged nodes to a user and to make it possible to evaluate a test pattern by setting a signal value which can be provided at each node (a signal line in the circuit of a logic simulation model including the circuit description at a transistor level) in response to the operation of an element model which is to become an input to said mode, and verifying said signal value. CONSTITUTION:When the operating state of a node is verified, a signal value which is provided at each node is set in response to the operating type of an element model which is to become an input to said node. With respect to a node which has a plurality of element models as inputs to the node and wherein logic values compete, the node is regarded as one wired logic element, and the operating state is checked. Thus, test-pattern evaluation for a logic simulation model of a digital circuit including the circuit description at a transistor level can be performed. Since the verification is performed for the result of the logic simulation, high-speed processing can be performed in comparison with fault detecting simulation. This system can be used for large-scale digital circuits.

Title: Method for processing aluminum floating sludge and residue of alminum floating sludge into calcium alminate
Inventor: BEELEN CHRISTIAAN MATHEUS JOSE
IPC: C01F7/164
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To obtain a slug having a rapid melting property and good fluidity by obtaining calcium aluminate in a glassy solid product state by rapidly cooling calcium aluminate formed as an at least partially melted material by reacting an aluminum dross residue with a calcium-oxygen compound at about a given temperature.

Title: Oriented film for liquid crystal display element
Inventor: ASAKUMA SUMITOSHI
IPC: C08G73/10
Filed: 1992-04-13
Abstract: PURPOSE:To apply a stable and high pretilt angle without depending on rubbing conditions by forming the oriented film of a polyimide resin contg. a fluorine atom and silicon atom in the molecule. CONSTITUTION:This oriented film is formed of the polyimide resin contg. the fluorine atom and silicon atom in the molecule. The polyimide oriented film contg. the fluorine atom gives the relatively high pretilt angle under a weak rubbing condition but the pretilt angle decreases drastically when the film is strongly rubbed. Since the weak rubbing condition is poor in reproducibility in terms of production process, the rubbing under the relatively strong condition is preferably executed. The liquid crystal oriented film consisting of the polyimide resin contg. the fluorine atom and silicon atom in the molecule, therefore, hardly changes the surface energy and attains the pretilt angle of the stable and high value even if the rubbing condition is changed. Then, the pretilt angle of the liquid crystal is hardly changed by the rubbing condition and, therefore, the element having the stable display characteristic is produced with high productivity.

Title: Protecting material for fixing guardrail
Inventor: KATO TAKATSUGU
IPC: E01F15/02
Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To protect a pedestrian walking on a sidewalk from injuries, or to make such injuries light even though the pedestrian collides with a fixing member that fixes a guardrail to a support. SOLUTION: Rubber protecting members 11 are attached to bolts and nuts fixing a guardrail 1, a cut member of steel material, to a support 2. Thereby, if a pedestrian walking on a sidewalk or a person riding on a bicycle falls accidentally on the bolts or the units, shock to the body is softened by elasticity of the protecting members 11, causing only a light bruise while not producing a heavy injury. Furthermore, safety is ensured because a little child playing nearby can be protected from injuries caused by the bolts or the nuts.
