Title: Manufacture of fuel injection pump
Inventor: OZAKI HISANORI
IPC: F02M59/44
Filed: 1992-06-23
Abstract: PURPOSE:To reduce the irregularity of fuel injection amount caused by a sleeve pivoting projection. CONSTITUTION:A sleeve pivoting projection 5 is molded integrally with a control sleeve 4 by a metal injection molding method. Thus, the irregularity of a fuel injection amount caused by the sleeve pivoting projection 5 is reduced. That is, since the sleeve pivoting projection 5 is molded integrally with a control sleeve 4 by a metal injection molding, the surface of the sleeve pivoting projection 5 has sufficient accuracy on the finished area while leaving the porosity as a sintered surface, so that the concordance with oil is good and the wear can be reduced. Also, compared with die casting, since the sleeve pivoting projection is made of a blank of high melting point metal having a high antiwear property and high strength, the wear and deformation of the sleeve pivoting projection can be reduced.

Title: Semiconductor integrated logic circuit device
Inventor: YAMAGUCHI MASAYA
IPC: H01L21/822
Filed: 1987-07-02
Abstract: PURPOSE:To prevent the floating state of a gate, and reduce the power consumption, by detecting the states of a plurality of power supplies, and constituting a logic wherein generated indefinite signals are prevented from entering other blocks. CONSTITUTION:A detector 1 compares a power supply V1 with a power supply V2, and outputs a signal 'H' when a state V1+alpha<V2 occurs. A two-input NOR 25, an inverter 26, and an NOR 27 of a semiconductor logic circuit are converted to a three-input NOR 5, a two-input NOR 6, and a two-input OR 7, respectively, and receive the output of the detector. When the power supply V1 is turned off, the output of each gate 2-4 becomes indefinite, but each gate 5-6 is determined by the output of a detecting equipment 1, so that the indefinite signal exerts no influence on the block 12. By preventing the input gate stage of the block 12 from turning into a floating state, it can be prevented that a current flows between the power supply and the ground in the block 12 and the lower consumption of the power supply V2 increases.

Title: Echo canceller
Inventor: SAKAI YOSHIHIRO
IPC: H04B3/23
Filed: 1990-06-25
Abstract: PURPOSE:To maintain echo canceling stably by providing an echo path gain estimate circuit estimating a gain of an echo path depending on a change ratio of a reception level and a transmission level so as to use it as a threshold level of double talk detection. CONSTITUTION:An echo path gain estimate circuit 9 estimates a gain of an echo path from a reception level Lr and a transmission level Ls. This is explained by using a figure in which the X axis indicates the reception level Lr and the Y axis depicts the transmission level Ls. Suppose that the reception level Lr changes with a variable component Dr and the transmission level Ls changes with a variable component Ds, then a ratio of the both k=Ds/Dr indicates a gain of an echo path 7, that is, an attenuation G. When the attenuation G is used for a threshold level K, it is not required to set the threshold level K with respect to the gain G and even when the gain G of the echo path changes halfway, sine the echo path gain estimate circuit 9 always revises the threshold level K, an accurate double talk detection is obtained and excellent echo cancellation is maintained.
