Filed: 1988-11-30
Abstract: PURPOSE:To make unnecessary complicated re-connection, input switching on a CRT display device side, etc., by providing a signal output terminal to output a signal reproduced by means of a recording/reproducing device, and a switch to selectively output a received signal by means of a satellite broadcast and the received signal by means of a ground broadcast. CONSTITUTION:To a fixed piece (8) of an output selective switch S3, the received signal is coupled by a base band BS obtained by selection-modulating a satellite broadcast (BS) wave by a BS signal processing circuit, and the received signal is coupled to a fixed piece (6) by the base band BC obtained by selection-demodulating a ground broadcast (BC) wave by the BC signal processing circuit. Further, the output selective switch S3 selects one of the signal by means of the BS, the signal by means of the BC or the signal switched by a change-over switch S2, and outputs it to a signal output terminal 9. Thus, by switching the output selective switch S3 on the (8) side, the received signal by means of the BS can be always outputted, and by switching it on the (6) side, the received signal by means of the BC can be always outputted to the signal output terminal 9 respectively.

Title: Air flow calculation of engine
Inventor: SAITO MASAAKI
IPC: F02D45/00
Filed: 1989-11-24
Abstract: PURPOSE:To obtain a true average flow of the pulsated air flow by converting a pressure difference sensor signal into a signal that is in linear relationship with a volume air flow through the arrangement of an analogue calculator on the input side of a signal processing circuit, and by performing an averaging process for the signal to the pulsated air flow, so as to calculate the volume air flow. CONSTITUTION:After the signal of a pressure difference sensor 4 that is not in a linear relationship with an air flow, is converted into a signal that is in a linear relationship with the air flow through an analogue calculator 14 (functional converter), an average process to the pulsation of the air flow is performed by a CPU 10 of a computer signal processing circuit 7, so as to calculate a volume air flow through the signal of an opening sensor 5 of a throttle valve 2. Calculation error is not to be generated thereby. Air density is calculated based on the signal of a pressure sensor 3 on the upper stream side of the valve 2, as well as on the temperature signal of a temperature sensor 6, and a mass air flow corresponding to the volume air flow is calculated. The average air flow of better accuracy than the average air flow calculated through the output averaging process of the pressure difference signal, can thus be obtained.
