Title: Aperture for automatic photodrafting machine
Inventor: AOKI MAKOTO
IPC: G03F1/76
Filed: 1988-12-14
Abstract: PURPOSE:To prevent the positional deviation at the time of selection of an aperture by providing a target mark for positioning feedback on the aperture. CONSTITUTION:The target mark 19 for positioning is provided on the aperture 9. For example, the aperture 9 with a target is packaged on an aperture turret 10 and a detector 21 for detecting the target mark is installed in the lower part of the target mark stop position of the aperture turret 10. An aperture selecting operation of the assigned position is executed by input data.

Abstract: PURPOSE:To measure flow velocity without agitating a flow state by taking the image of a fluid at a predetermined time interval and calculating the center of gravity of the element to be measured moving along with the fluid at each time when the image is taken. CONSTITUTION:The image of a fluid is taken at a predetermined time interval and the centers of gravity of the elements 11 - 14 to be measured moving along with the fluid at each time when the image is taken are calculated. The nearest distances between the centers of gravity of the elements 11 - 14 in the photographing of this time and those in the photographing of the previous time are regarded as the moving distances of the elements 11 - 14 between the photographing of this time and that of the previous time by sufficiently shortening the time interval of photographing. By dividing the nearest distances between the centers of gravity by the time interval, the velocities of the elements 11 - 14 are calculated. By setting a large number of the elements 11 - 14, the flow velocity distribution of the fluid can be accurately measured without agitating a flow state.

Title: Switching control type thermal flow rate sensor
Inventor: TANIMOTO KOJI
IPC: G01F1/698
Filed: 1988-12-12
Abstract: PURPOSE:To enable measurement in a wide flow rate range by providing a differential amplification circuit for amplifying an output of a bridge circuit with a phase delay compensation circuit to compensate a phase delay thereof. CONSTITUTION:In a differential amplification circuit for amplifying an output of a bridge circuit, a series circuit of a resistance 26 and a capacitor 27 is connected in parallel to a feedback resistance 9. A resistance value of the resistance 26 is set smaller than the resistance 9. The resistances 9 and 26 and the capacitor 27 compose a phase delay compensation circuit. A frequency characteristic of an AC differential gain in the differential amplification circuit provides a frequency response characteristic higher in DC differential gain and lower in high frequency gain by selecting values of the resistance 26 and the capacitor properly. Thus, in regard to a frequency response characteristic for fine changes in flow rate as sensor, a frequency characteristic having the optimum attenuation characteristic can be obtained with the lowering of the AC gain of the differential amplification circuit.

Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To obtain a phenolic resin in high yields without causing gelation by reacting a phenol with an aldehyde in the presence of a catalyst being a Lewis acid of europium. SOLUTION: A phenol (e.g. phenol) is reacted with an aldehyde (e.g. paraformaldehyde) in the presence of a catalyst being a Lewis acid of europium, desirably europium tris(trifluoromethanesulfonate). When the aldehyde used is formaldehyde, it is desirable that the Lewis acid of europium is used in an amount of 0.001-300 mol.%, particularly 0.01-200 mol.% based on the formaldehyde. This reaction can be performed in a solution system or a solventless system. It is generally suitable that the molar ratio of the aldehyde to the phenol is 0.4-5.0. The necessity of feeding an excess of the phenol to avoid gelation can be eliminated.
