Title: Signal output circuit
Inventor: TAMAKI KENJI
IPC: H03K17/60
Filed: 1988-12-12
Abstract: PURPOSE:To realize a low output impedance and at the same time to increase the noise resistance by using a switching means which energizes cuts off an output signal and has a 1st impedance at the time of energizing and then a 2nd impedance larger than the 1st impedance in a cut state respectively. CONSTITUTION:A transistor TRQ13 is cut off in response to an input signal Sin when TRQ12 is energized, and an output signal So is energized between output terminals P1 and P2 in the timing set by the signal Sin. The TRQ13 is energized when the TRQ12 is cut off and both ends of a resistor R16 are short-circuited. Therefore, a low impedance state is always kept between both terminals P1 and P2. Then the resistance is increased to the external noises despite the connection of a long transmission cable and therefore the S/N is improved.

After the resin 2 is surely cured, second step of thermal spraying is executed by using the same material as the thermal spraying material 3 of the first step, by which the thick film of the thermal spraying material 6 integrated with the thermal spraying material 2 of the first step is formed. As a result, the surface of the base material 1 is coated with the films having a high adhesion property and the products having a long life are obtd.

Title: Field of view tester
Inventor: WEBER JOERG
IPC: A61B3/02
Filed: 1988-12-15
Abstract: PURPOSE: To exactly measure a threshold value in a comparatively short time by performing illumination from a controller for light spots arranged back and forth while strengthening a strength step on a stage for improving strength or while weakening a strength step on a stage for weakening the strength. CONSTITUTION: The controller selects a strength coefficient corresponding to an inter-threshold difference but in that case, the step on one stage is improved with the increase of strength and the step on a certain stage is decreased with the weakening of strength. Thus, when changing the threshold value, for example, it is performed like 0, 6, 11, 15, 19, 22, 25, 28, 30, 32, 33, 34 and 35dB. Therefore, the step is decreased while having continuity from 6dB to 1dB. Then, by performing control so as to execute illumination with strength having the step through two light spots at least on respective stages without being affected by the change of an answer, comparatively high stability can be provided. Besides, the condition showing the number of times of light spot display is remarkably improved in spite of provided accuracy.

Abstract: PURPOSE:To shorten a cable, to facilitate handling and to improve operability by providing a rotating fulcrum at an inserting position of a cable of an electric instrument box, eliminating movement of an inserting unit of the cable and obviating variations in lengths of the cable at the times of non-rotating and rotating. CONSTITUTION:An electric instrument box 9 has a case which contains a controller, a capacitor, a transformer and a terminal block. A support pin protrudes outside at a side of the case at a sidewall 60 side, and is removably engaged with engaging grooves formed at each one end of supporting plates 13a, 13b. Thus, the case is rotatable from a horizontal direction to a vertical direction. Since the box 9 is rotated toward a lateral sidewall 60 side, a cable 26 connected in the box 9 is disposed at a supporting pin side as a rotary shaft, and hence a length of the cable 26 does not alter by the rotation. Accordingly, the length of the cable 26 can be made shortest, and the cable 26 does not disturb an operation.

Title: Packer for filling column
Inventor: IKEDA HIROKAZU
IPC: G01N30/56
Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To obtain a high theoretical stage number and improved peak symmetry by providing a capillary part and a thick pipe part, setting the inner diameter of the capillary part to a specific number of times larger than that of a column, and setting length in the direction of an axial line to a specific value or larger. SOLUTION: A packer 1 is provided with a thick-pipe part 3, a tapered connection part 4, and a capillary part 2. The cylindrical capillary part 2 is connected to the upper end part of a column via a joint with a different diameter and the inner diameter is set to 1-2 times larger than the inner diameter of the column. When the inner diameter is smaller than the inner diameter of the column, a load area applied to a support material filled into the column is reduced, so that the support material in the column cannot be clamped fully. When the inner diameter exceeds a value that is two times larger than the inner diameter of the column, much support material needs to be prepared, which is not preferable in terms of costs.  Also, by setting length in the direction of an axial line to 10 mm or longer, the reproducibility and peak symmetry of the column performance when slurry is filled can be improved. By setting the inclination angle of a tapered connection part 4 to 30-45 deg., a solid part in the slurry moved smoothly from the thick-pipe part 3 to the thin-pipe part 2 without adhering to the wall of the thick-pipe part 3.
