Title: Method and device for mixing fluids and air conditioner utilizing this device
Inventor: KONDO FUMIO
IPC: B01F23/10
Filed: 1989-01-12
Abstract: PURPOSE:To completely mix fluids in a short mixing zone without increasing the flow resistance by allowing the fluids to be mixed in the mixing zone to collide with a mixing accelerator arranged at a mixing boundary, thereby generating large vortices alternately from both ends and mixing the fluids. CONSTITUTION:At least two fluids (a) and (b) are joined in the mixing zone 23, and mixed. In this case, the mixing accelerator 25 is set at a position of the mixing boundary 24 where the fluids to be mixed in the mixing zone 23 are mixed, and both ends of the accelerator are allowed to protrude into the currents of the fluids. The fluids (a) and (b) to be mixed in the mixing zone 23 are allowed to collide with both ends of the accelerator 25, hence the large vortices 28 and 29 are generated, and both fluids are mixed. As a result, the fluids are completely mixed in the short mixing zone without significantly increasing the flow resistance.

Title: Vibration testing method
Inventor: YOKOTA AKIHIKO
IPC: G05D19/02
Filed: 1985-01-16
Abstract: PURPOSE:To vibrate a vehicle under a condition which is very similar to an actual vibration, by multiplying an error to the aimed signal of an actually working signal or a value corresponding to the error by a coefficient smaller than '1' and correcting an initial excitation signal and its successive excitation signals by using the multiplied value. CONSTITUTION:An aimed signal having the aimed waveform of a vehicle A at the location of a detector 5 is determined by measuring the output signal of the detector 5 by adding a vibration signal of a prescribed waveform to the exciter 1 of a system provided with the vehicle A, to which vibration is added from the exciter 1, and the detector 5 fitted to an optional position of the vehicle A and finding the transfer function of the system. An initial excitation signal is found on the basis of the aimed signal and transfer function and added to the exciter 1. In this case, an error to the aimed signal of an actual working signal detected 5 at the time or a value corresponding to the error is multiplied by a factor smaller than '1' and the initial excitation signal and its successive excitation signals are corrected by using the multiplied value. Therefore, the possibility of divergence of the error value of the excitation signals due to over-correction can be eliminated and the error is converged to a relatively small value in a short time. As a result, the testing time can be shortened and the vehicle A can be vibrated under a condition which is very similar to an actual vibration.

Abstract: PURPOSE:To facilitate reduction of the saturation voltage between the collector and emitter of an NPN transistor of a low breakdown strength part and obtain the low breakdown strength characteristics equivalent to the characteristics of a low breakdown strength IC by a method wherein an N-type well region is formed in the low breakdown strength region except the active base region of the lateral PNP transistor in the low breakdown strength region. CONSTITUTION:An N-type well region 6 is formed in a low breakdown strength region except the active base region of a lateral PNP transistor of a low breakdown strength part and a bipolar IC in which a high voltage part and the low voltage part coexist is produced. With this constitution, not only the characteristics of the high breakdown strength part can be maintained but also the saturation voltage between the collector 9.1 and emitter 9 of the NPN transistor can be lowered. Further, the degradation of the current amplification factor of the lateral PNP transistor can be eliminated. Therefore, though the high breakdown strength part and the low breakdown strength part coexist in one IC, the low breakdown strength characteristics equivalent to the characteristics of an IC with only the low breakdown strength part can be maintained.
