Title: Flow rate measuring apparatus for upright drain pipe
Inventor: TOKUNAGA KENSUKE
IPC: G01F1/00
Filed: 1987-07-13
Abstract: PURPOSE:To enable the obtaining of a correct measured value for a long time, by a method wherein a means of digital values of measurement signals of the intensity of vibration in an upright drain pipe for each specified time length to judge the maximum value of a specified number of the means and a flow rate corresponding to the maximum value is calculated according to a correlationship between a downflow rate of the upright drain pipe and the intensity of the vibration. CONSTITUTION:An analog signal of the intensity of vibration of an upright drain pipe 1 measured 10 is converted 11 into digital from analog to be inputted into a computer 12. Here, a mean value of digital values of the signal is determined for each specified time length. Then, the maximum value of a specified number of the means is judged. A flow rate for the maximum value is determined from a correlationship between the intensity of vibration of the drain pipe 1 and a flow rate of a drain while it flows from a drain apparatus. Thus, a correct flow rate of the drain can be measured using the computer 12.

Filed: 1998-06-22
Abstract: PROBLEM TO BE SOLVED: To provide a design method which can effectively suppress leakage of electromagnetic waves generated from a wave generation source built in an electronic apparatus casing made of a pair of halves arranged as opposed to each other by means of pre-test measures. SOLUTION: An electronic apparatus casing 10 is made up of a pair of halves 11 and 12 which can have an electromagnetic wave shielding function and can accommodate an antenna 20 when positioned as opposed to each other. A gap 13 is defined between opposing ends of the halves 11 and 12 when positioned as opposed to each other.  An intensity of electromagnetic waves radiated from the antenna 20 and externally leaked from the casing halves 11 and 12 is predicted by a simulation technique, a value is found based on its predicted result so that the intensity of electromagnetic waves radiated from the antenna 20 and externally leaked from the casing halves 11 and 12 becomes smaller than that substantially in the absence of the gap 13, and the found value is employed as a gap dimension between the opposing ends of the paired easing halves positioned as opposed to each other to form the electronic apparatus casing.

Abstract: PROBLEM TO BE SOLVED: To enable automatically setting of the optimum center point of inclination during the movement of focusing by comparing a difference between a focusing position data and a center point of inclination data with a preset difference data to correct the center point of inclination based on the results. SOLUTION: When a center point of inclination setting switch is depressed, an objective lens position signal is inputted into a control section 102 from an objective lens position detecting section 57 and an inclination rod position signal thereinto from an inclination rod position detecting section 44. The control section 102 calculates a distance R from an intersection T1 of rotating shafts 09, 010 and 020 of a mirror body 12 to a focusing point P. A distance R2 is calculated between an intersection T1 of shafts 012 and 021 of an inclination rod motion regulating mechanism 40 and an intersection S2 of rotating shafts 023, 024 and 030. A value obtained by multiplying the distance R2 by a ratio of similar triangles is compared with the distance Rf to control a second driver circuit 104 so that the both are equal.  Thus, an inclination rod drive section 43 moves an inclination rod 25 to set the center point of the inclination of the mirror body 12 to an aimed point.

Abstract: PROBLEM TO BE SOLVED: To surely prevent jumping of a motion part from generating in a motion part by arranging a volume part which is substantially closed when a follower body is oscillated beyond a prescribed angle to a follower shaft, which is arranged for generating restraint for suppressing oscillation of the follower body in lubricating oil. SOLUTION: When a follower body 9 is oscillated around a follower shaft 10 in the case where inertia force of a moving part is increased more than elastic force of a valve spring to be jumped, in the near part where a cam 11a is lifted to the maximum level, a volume part 21 is not communicated with a groove 3 formed as an inlet side for lubricating oil, and the volume part 21 becomes in a closed condition substantially. When the follower body 9 is oscillated larger than a maximum cam lift position by inertia force of the motion part, the volume of the volume part 21 is contracted, lubricating oil in the volume part 21 is pressurized, and pressure is generated. By this pressure, oscillation of the follower body 9, namely, jumping of the motion part is suppressed.

IPC: G11C11/417
Filed: 1989-07-05
Abstract: PURPOSE:To shorten delay time and to reduce the over-shoot and under-shoot of an output waveform by providing a control circuit to vary the driving ability of each transistor during a transition period of the output waveform of a driving output signal. CONSTITUTION:Control circuits 1 and 2 are provided to control input signals, which are applied to the respective control terminals of plural transistors T1-T4 constituting a semiconductor output circuit, and to vary the driving ability of each transistor during the transition period of the output waveform. The control circuits 1 and 2 divides the transition period of the output waveform into three periods. In a first period, a first transistor T1 is turned ON, in a second period, the first transistor T1 and third transistor T3 are turned ON and in a third period, the first transistor T1 is turned on. Thus, since an amplitude to sharply change the rise and fall of the output waveform is limited by controlling the driving ability, the over-shoot / under-shoot can be reduced and the delay time is shortened.
