Title: Surface wave filter
Inventor: YAMAJI NOBUKI
IPC: H03H9/25
Filed: 1980-03-25
Abstract: PURPOSE:To improve the characteristic, by forming the piezoelectric substrate into a triangle in the surface wave filter obtained by causing the piezoelectric substrate, where the input electrode and the output electrode are formed on the surface, to adhere to the stem. CONSTITUTION:Triangular piezoelectric substrate 11 divided into two by a diagonal line is used to form a surface wave filter. Consequently, since weighting part 16 of input electrode 12 can be formed in the same manner as the conventional surface wave filter, the electric signal is converted to a surface wave mechanically and is propagated toward the output electrode according to the prescribed method. Since acoustic absorbing layer 14 of electrode 12 exists in the region where the surface wave is converged, this spread of the area is sufficient for it.

Abstract: PURPOSE:To make it possible to display a good magnetic domain contrust image and the like, by furnishing an amplifier circuit to amplify the output signal of a subtracter circuit, and a divider circuit to divide the output of the amplifier circuit by the secondary function signal. CONSTITUTION:The output signal of an adder circuit 10 is multiplied by a coefficient K' at a coefficient circuit 12, and then delivered to a subtracter circuit 13. At the subtracter circuit 13, an output signal from a reflection electron detector 3 through a preliminary amplifier 14 is delivered, and the output signal of the subtracter circuit 13 is multiplied at a multiplier 15, and then delivered to a divider circuit 16, where the output signal from the coefficient circuit 12 is delivered. As a result, signal from which uneven DC component is removed is output from the subtracter circuit 13, and amplified to 1,000-2,000 times in the amplifier 15. Since the output signal of the amplifier 15 is delivered to the divider circuit 16, the responding output can be gained from the divider circuit 16, and, depending on such an output signal, the sample image can be displayed on the CRT 6. Therefore, a good quality of image with an even brightness and even contrust over the all screen can be displayed.

IPC: F16T1/22
Filed: 1989-02-15
Abstract: PURPOSE:To eliminate turbulence or pipeline resistance and increase the rate of exhaust flow by arranging a valve hole, which puts the valve chest in communication with an outlet passage, so as to open in the valve chest, and by locating the axis of the valve hole approx. on a straight line. CONSTITUTION:An inlet passage 6 and outlet passage 7 are formed in the upper part and lower part of the body 1 of a valve casing, respectively. A valve hole 10 puts a valve chest 4 in communication with the outlet passage 7 to lead the condensate in the chest 4 out to the outlet passage 7. The valve hole 10 is in a shape increasing the width gradually and is formed approx. coaxially to the outlet passage 7. A hollow spherical float 8 is accommodated in the valve chest 4 in free state. This float 8 lies afloat on the condensate stagnating in the valve chest 4, making rise and fall together with the liquid surface. This eliminates turbulence and/or pipeline resistance from the valve hole to the outlet passage, which permits increase of the rate of exhaust flow.

Title: Method of testing cis-diol or glycocylated hemoglobin and reagent for test used for said method
Inventor: HIRU HAU AREN ORIBAA
IPC: C07F17/00
Filed: 1986-02-21
Abstract: The invention disclosed relates to an electrochemical assay which is particularly concerned with an assay for the presence of, or amount of, glycosylated haemoglobin in a blood sample, but which extends a general assay for detecting the presence of, monitoring the level of or determining the concentration of compounds containing cis-diol groups, such as glycols, nucleic acid components, sugars, polyols, catechols and glycosylated proteins.When ferrocene boronic acid or a derivative thereof is present free in solution, it can act as a mediator for a wide range of oxido-reductases. Howeverin the presence of, for example. sugars containing the cis-diol structure, the metallocine (such as ferrocene boronic acid) covalently binds to the sugar. When the ferrocene boronic acid is thus bound, it is essentially immobilized and its properties as a mediator and ability to diffuse will be markedly affected.

IPC: H03K5/1252
Filed: 1980-03-26
Abstract: PURPOSE:To prevent the occurrence of a glitch securely by simple constitution by making the rise time and fall time of a digital output signal coincide with each other by delaying its rise or fall or by advancing it. CONSTITUTION:If a digital signal outputted from digital signal output device 11 changes from [1, 0, 0...0] to [0, 1, 1...1], the most significant digit bit MSB, before the other bits reach level [1], has rised up to level [0], so that a glitch occurs temporarily. On the other hand, MSB is integrated by integrating circuit 16 in glitch preventing circuit 13 to delay the fall time. The output of this integrating circuit 16 is sent to D/A converter 12 via buffer 17. Thus, the fall time of MSB is delayed to coincide with the rise time of the other bits.
