Title: Throttle valve body
Inventor: YAMADA HIROYUKI
IPC: F16K1/22
Filed: 1991-12-25
Abstract: PURPOSE:To improve air-tightness of the whole throttle valve body in the valve throttle body which is provided with a butterfly-type throttle valve an a throttle valve stem by changing flexural rigidity of respective throttle valves corresponding to inlet air passages which are divided from the rotational center of the throttle valve. CONSTITUTION:A throttle valve body 1 is disposed at an inlet air passage 2. The inner peripheral surface of the inlet air passage 2 is formed with a projecting part 1a which projects toward its inside. Throttle valves 4a, 4b are installed to the throttle valve body 1 so as to rotate with a throttle valve axial center 3 centered. An upper part is kept under a high pressure and a lower part is kept under a low pressure so that fluid flows from an upper part to a lower part. Under these conditions, a section of the throttle valve 4a where the throttle valve inclines upwards is thinner than that of the throttle valve 4b where the throttle valve inclines downwards, and flexural rigidity on the throttle valve 4a side is lower than the throttle valve 4b side, so that the shape can be changed easily by load generated due to a difference in pressure on the upper and lower sides. It is thus possible to improve air-tightness of the whole throttle valve body and absorb dispersion by dimensional accuracy or the like.

Title: Fm multiplex receiver
Inventor: NOGUCHI TAKENORI
IPC: H04L27/14
Filed: 1992-12-01
Abstract: PURPOSE:To demodulate multiplex signals without affected by triangular noises by directly performing an MSK demodulation from an IF signal. CONSTITUTION:An antenna input signal from an antenna 1 flows through an FE 2 (front end) and obtains an IF signal (intermediate frequency component signal). Then, an output of the FE2 is inputted to a BPF 3 to extract the only one side wave band component of the IF signal component. The level of the output signal of the BPF 3 fluctuates. But the vibration fluctuation component can be eliminated by a limiter 4 as an MSK signal has no information in the amplitude direction. The output of the limiter 4 is demodulated by an MSK demodulating device 5 and becomes an MSK demodulating signal.
