Title: Bellows type target flowmeter
Inventor: WATANABE HISAO
IPC: G01F1/28
Filed: 1981-06-01
Abstract: PURPOSE:To achieve a highly accurate measurement of flow rate by providing a cylindrical wall pressure bellows orthogonal to the axis of a piping with one end thereof fixed on the bottom of a concave section provided orthogonal to a piping wall, a wall pressure receiving plate where the other end of the bellows is sealed and a tube for communicating bellows. CONSTITUTION:When a solid-gas mixed phase flow containing granular solid flows through a piping 1, the granular solid hits against a pressure receiving plate 3. The impact is applied to the plate 3 to reduce a bellows 2 in proportion to the load causing a change in the distance between the pressure receiving plate 3 and a displacement gauge 6. With the reduction of the bellows 2, gas therein raises the pressure in a wall pressure bellows 8 through a communicating tube 10 to push a wall pressure receiving plate 9 from inside. When a pressure works inside and outside the pressure receiving plate 9, the plate balances. Thus, the pressure within the wall pressure bellows 8 and the pressure within the bellows 2 can be maintained at a static pressure in the piping 1.

Title: Ignition angle advancing device for internal combustion engine
Inventor: WATANABE KENZOU
IPC: F02P5/155
Filed: 1982-05-20
Abstract: PURPOSE:To enable fluctuation of angle advancing characteristics to be prevented by comparing reference voltage with trapezoidal wave output having the front edge at the max. angle advancing position and the rear edge at the min. angle advancing position. CONSTITUTION:The front edge of trapezoidal wave output is at the max. angle advancing position and the rear edge at the min. angle advancing position. As the rotational frequency of an engine is increased, the wave height value of the trapezoidal wave output is increased. In low speed, the trapezoidal wave output does not coincide with the reference voltage V(R). In this case, ignition occurs at the min. angle advancing position. In medium speed, the trapezoidal wave output coincides with the reference voltage at the slant portion and ignition occurs at the coincidence point. In high speed rotation, the trapezoidal wave output coincides with the reference voltage at the max. angle advancing position. Thus, angle advancing exceeding the max. angle advancing point and angle delaying exceeding the min. angle advancing point can be prevented and the fluctuation of angle advancing characteristics can be prevented.

Title: Decision feedback type equalizer
Inventor: KUROUE YUUZOU
IPC: H03H21/00
Filed: 1995-03-15
Abstract: PURPOSE: To prevent equalizing ability from being rapidly degraded by the increase of a noise component. CONSTITUTION: A non-equalized signal Sr is outputted as a forward equalized signal Sfe after inter-code interference caused by advance echo is removed by a forward equalizer 12. An adder 14 adds the forward equalized signal Sfe and a backward equalized signal Sbe and generates an equalized signal Se. A discriminator 15 outputs a discriminate signal Sd. The discriminate signal Sd is outputted as the backward equalized signal Sbe after inter-code interference caused by delay echo is removed by a backward equalizer 13. A subtracter 16 outputs an error signal Sf expressing the remaining amount of equalization due to the equalizer by finding the difference between the disriminate signal Sd and the forward equalized signal Sfe.  An alarm generator 17 monitors line quality based on the error signal Sf and when it is degraded rather than line quality decided in advance, the alarm generator generates an alarm signal and performs control so that the equalized signal Se can be selected by a selector 18.
