Title: Power supply apparatus and overcurrent alarm apparatus
Inventor: ISHIHARA TOSHIKAZU
IPC: H02J3/00
Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To obtain a power supply apparatus and an overcurrent alarm apparatus that assures to issue the warning for an overcurrent without operation of an over-current shut-off breaker at the time of loading of a new power load. SOLUTION: A power supply apparatus 500 supplies a power to each power distributing paths 102A to 102C via an overcurrent shut-off breaker 60 from a power feeding line 100. When a new power load 201D is connected to a distribution path 102C, connection is not immediately established, but an additional current detecting part 150 detects an additional current x1 required by a power load 201D and then communicates it to a remaining current detecting part 160. The remaining current detecting part 160 determines whether a residual current value (a1-y1) that is equal to the difference between the present current value y1 and the regulated current value a1 of the overcurrent shut-off breaker 60 is equal to or larger than the additional current value x1. When these are equal, a power is supplied, but when these are not equal, overcurrent alarms 158A/158B are issued.  When an overcurrent shut-off breaker is also provided in the distribution paths 102A to 102C, similar determination is performed to execute the connection or alarming operation. An additional current detection part 150 and a residual current detecting part 160 are also provided as an overcurrent alarm apparatus 600.

Title: Developing method for control program
Inventor: HARADA YASUHIRO
IPC: G06F9/06
Filed: 1991-03-29
Abstract: PURPOSE:To prevent a change on an unexpected control function by tuning a program module defined as a global variable and/or local variable, at the time of changing the control characteristic of a controller. CONSTITUTION:The entire control of an engine controller is decomposed into plural program modules, and the structure of the entire control is expressed as the depending relation of data among the program modules. Then, a variable commonly used for more than two program modules is defined as the global variable, and the variable used only for one program module is defined as the local variable, so that the control characteristic can be changed only by tuning each program module, by the tuning which is often operated in the developing process of a control program. Thus, the change on the unexpected control function can be prevented even when one part of the program is corrected.

Title: Mass flowmeter
Inventor: HASEGAWA HIROAKI
IPC: G01F1/84
Filed: 1987-03-20
Abstract: PURPOSE:To enhance the stability of a zero point and the linearity of the output signal of a pickup, by providing a sensor tube wherein an alpha-shaped bent part is formed to the straight pipe part between an inflow port and an outflow port. CONSTITUTION:At the time of the measurement of a flow rate, a fluid to be measured from an inflow port 2 is divided in an almost equal flow dividing ratio to flow through branch pipes 2a, 2b and passes through bent parts 4b, 5b to flow in branch pipes 3a, 3b. Next, the fluids passing through a pair of sensor tubes 4, 5 are met through the branch pipes 3a, 3b to flow out from an outflow part 3. When the sensor tubes 4, 5 are respectively vibrated by vibrators 9, 10, said tubes 4, 5 vibrate at the inherent vibration frequency determined by the spring constants of the tubes 4, 5 themselves and the mass of the fluid flowing through the tubes 4, 5. When the fluid to be measured flows through the vibrating tubes 4, 5 as mentioned above, Coriolis force is generated in straight pipe parts 4, 5. Therefore, by utilizing the fact that the displacement difference between the tubes 4, 5 generated by Coriolis force is proportional to the mass of the fluid flowing through the tubes 4, 5, a flow rate can be measured.

Abstract: PURPOSE:To operate an automatic chopping circuit correctly, by giving a hysteresis characteristic to a circuit where the comparison with the reference value of an automatic chopping circuit is made, and keeping the light source in a chopped state even if the input level of the comparison circuit is changed after being chopped once. CONSTITUTION:An LD(semiconductor laser)2 is driven with a driving circuit 1 according to an input signal. Further, it is monitored by a photodiode 3 and an LD level is detected by a peak detecting circuit 5. This level is fed to an APC (automatic output controlling circuit)6 and feedback is given to the circuit 1. On the other hand, the peak value level is inputted to a comparator 8 having hysteresis to be compared with the reference value, and if the peak level is low, the input signal is cut off with a chopping gate 9 and deteriorated LDs are chopped. After that, although the input to the comparator 8 is increased up to a pseudo output level by a protection circuit 10, since the upper-limit threshold level is set higher than the pseudo output level, the output of the comparator 8 is not changed, allowing to complete the automatic chopping of an LD2 smoothly.
