Title: Envelope detection circuit

IPC: H03F1/56
Filed: 1991-05-31
Abstract: PURPOSE:To correct the sensitivity in response to an input signal level and to implement envelope detection to the input signal by connecting a DC amplifier in cascade with the detection circuit comprising a semiconductor IC. CONSTITUTION:A DC amplifier 1 consists of DC amplifiers G1-Gn of parallel connection, the mutual conductance of them different from each other and the input dynamic range is set smaller than the input level. The amplifier gain being the combination of parallel connection of gm1-gmn is obtained at an input of a very small signal. When the level of the signal is increased and the level reaches a dynamic range of an amplifier G1 depending on the gm1 or over, the G1 is saturated, the gain depends on the gm2-gmn, which is smaller than the former gain. The input signal level increases, the amplifiers G2, G3... are saturated one after another and the gain of the amplifier is gradually decreased. Finally only the Gn depending on the gmn remains and this indicates that the gain of the amplifier is changed in response to the input level.

Abstract: PURPOSE:To prevent gas in a heating zone from mixing into a cooling zone by arranging a CO gas analyzer near the inlet of a shield tunnel and blowing new atmospheric gas from the lower part of the tunnel according to this indication. CONSTITUTION:The CO analyzer 5 is set near the inlet of the shield tunnel 4 formed with a partition wall 3 between the heating zone 1 and the cooling zone 2. At the time of operating, the condition of gas in the heating zone accompanied with the band steel 8 is detected with an analyzer 5.

Title: Stretch bending process
Inventor: UENO SHIGEYASU
IPC: B21D7/06
Filed: 1977-12-26
Abstract: PURPOSE: To provide products of high precision, the variation of spring back amount is reduced by first stretching a material to be treated with a force greater than its yield strength, and then stretchingly bending under load of smaller stretching force.  
     CONSTITUTION: In stretch bending process, variation of spring back generally occures partly because a variely of yield strength is distributed in a material to be treated. To improve spring back phenomenon, a first tensile which is greater than the maximum yield strength is applied to the material to uniformalize yield strength of the material, and then stretch bending is performed. The process reduces variations relating to neutral axis positions and spring back amount. This results in the reduction of total material variation thereby effecting production of high accuracy.

Abstract: PURPOSE:To eliminate necessity of a seal part for fuel, by integrally combining together a housing and a fuel pipe through a non-magnetic material member, namely, separating an exciting coil from a fuel flow passage part. CONSTITUTION:By feeding an exciting current to an exciting coil 31, a stator 32, a fuel passage pipe 29, and a pole face 21a on the opposite side to the opening end part of a housing 21 are excited to inject fuel through a nozzle 26. Thus, since the pole face 21a and the fuel passage pipe 29 are combined together through a non-magnetic member 30, the exciting coil 31 side is separated from the fuel passage, and the fuel is fed in an opening 36 through the fuel passage pipe 29 without leakage. Furthermore, because of the non-magnetic property of member 30, the exciting current flowing between the pole face 21a and the fuel pipe 29 is shut off and a magnetic attracting force is effectively exerted.
