Title: Latch circuit
Inventor: KANAI YASUNORI
IPC: H03K3/037
Filed: 1984-11-19
Abstract: PURPOSE:To prevent the software error due to a spike electromotive force caused by irradiation of an alpha ray by inserting a low pass filter consisting of a resistor and a capacitance to a feedback loop in a latch circuit having plural logical gate circuits and the feedback loop feeding back an output of at least a logical gate circuit to an input of the other logical gate. CONSTITUTION:Suppose that a data is stored in the state that an output Q is at a high level and an output Q' is at a low level and a negative noise pulse is caused to, a node A, by alpha ray irradiation in this state. The noise pulse is fed to a base of a transistor (TR) T6 via a TR T14 to cut off temporarily the TR T6 so as to generate a positive noise pulse to a node B. When a low pass filter LPF is inserted between an emitter of the TR T16 and the base of a TR T2 in this case, the noise pulse caused at the node B is not transmitted to the base of the TR T2 so as to prevent the inversion of a stored data.

Title: Image recording device
Inventor: OBATA SHIGERU
IPC: B65H23/188
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To prevent misalignment of color or printing patterns caused by vibration in the sheet conveying direction in continuous paper such as rolled paper or folded paper. SOLUTION: Continuous paper 1 is led through a speed variation preventing means 2 by means of a drive roller 62 or the like, and is then fed into an image recording part 4a by a tractor 3a. The speed variation preventing means 2 winds the paper onto a pair of upper and lower rollers which are driven by a conveying force for the paper, so as to clamp the same in order to prevent vibration of the paper in the conveying direction. The upper roller 201 is composed of roller parts 21a, 21e arranged widthwise of the paper, and a paper clamping part is rotatably attached to the left and right arms 203, 204 which are rotatably attached by a shaft 207 at their fulcrums. The lower roller is composed of a straight or a crown roller 202 extending over the entire width of the paper. A spring 205 effects a clamping force for the paper.  Variation in speed is prevented upstream of the image recording part, thereby it is possible to prevent vibration of the paper in the conveying direction, caused by paper supply motion or the like.

IPC: G01N9/00
Filed: 1992-07-27
Abstract: PURPOSE:To measure the concentration of antibiotic material in the solution of the antibiotic material readily and highly accurately by attaching lipopolysaccharide or the material obtained by the chemical treatment of the lipopolysaccharide to an electrode element. CONSTITUTION:In this material-concentration measuring method, lipopolysaccharide or the material obtained by chemically treating the lipopolysaccharide is attached to an electrode element, and the concentration of antibiotic material in the solution of the antibiotic material is measured. The lipopolysaccharide and lipid A, which are extracted and separated from the cell of Gram-negative bacterium, mutually react with the antibiotic material in the solution. The weight and the fluidity are changed in a the intrinsic pattern by the antibiotic material. Meanwhile, the resonant frequency and the resonant resistance of the electrode element of a quartz microbalance indicate the weight change of the surface of the element and the fluidity of the material, respectively. Therefore, the thin films of the lipopolysaccharide and lipid are attached to the surface of the electrode element, and the concentration of the antibiotic material can be found based on the weight change and the fluidity change. It is preferable that cyanobacterium, Escherichina coli tribe cell, Salmonella tribe cell and the like are produced among the Gram-negative becterium for the lipopolysaccharide. The lipid A is obtained by separating the polysaccharide by acid hydrolysis.
