Title: Gain control amplifier
Inventor: FUJIMORI SHIGEO
IPC: H03G3/00
Filed: 1978-04-13
Abstract: PURPOSE:To prevent the deterioration of the cross modulation properties and others by avoiding a big change of the bias conditions for the differential amplifier of the next step when the gain control is given. CONSTITUTION:The collector voltage of transistor Tr11, i.e., the base voltage of differential amplifier 21 of the next step is decided by the sum of the collector current of Tr11 and 13 plus the value of load resistance 15. Thus, the base voltage of amplifier 21 can be kept constant as long as the sum of the collector current is constant. Now if the potential at point A is lowered and the collector current flowing to Tr11 is reduced, the collector current of Tr12 is reduced simultaneously. As a result, the base voltage of Tr13 increases and also the collector current of Tr13 increases. And the sum of the collector current becomes nearly constant between Tr11 and 13. In case this relation is satisfied substantially, the base voltage of amplifier 21 can be kept nearly constant even with the gain control given via the gain control amplifier of the preceding step.

Abstract: PURPOSE: To obtain necessary outputs with low voltages, by installing in parallel differential current gates and transistors for controlling the by-pass of the differential current gates between the power source terminal and the GND in such a way that the number of longitudinally connected connecting elements is reduced.

In the inverse case, a device 1 performs normal differential amplification by means of the transistors Tr 1a  and Tr 1b  and the fixed source 41. A device 2 also works in the same way.

Abstract: PURPOSE:To enhance the maneuverability and safety of a vehicle by controlling a desired rear wheel steering speed which is determined in accordance with a front wheel steering speed, so that the rear wheel in-phase steering speed is increased and decreased in accordance with a front wheel steering speed in a high or middle speed range. CONSTITUTION:During steering of a vehicle a computing section 103a in a desired steering computing means 103 determines a desired rear wheel steering angle in accordance with outputs from a front wheel steering force detecting means 100 and a vehicle speed detecting means 101. Then, a computing section 103b computes a deviation between the desired rear wheel steering angle and an actual rear wheel steering angle detected by a detecting means 104, and a computing section 103c determines a first desired rear steering speed in accordance with the deviation and a second desired rear wheel steering speed in accordance with an output from a front wheel steering speed detecting means 102. In this arrangement, the characteristic of the second desired rear wheel steering speed is set such that the rear wheel in-phase steering speed is increased if the front wheel steering speed is high in a high or middle running speed range. Further, the desired rear wheel steering speed is determined with the sum of the first and second desired speeds.

Title: Noise canceler
Inventor: FUDA HITOSHI
IPC: G10L21/0208
Filed: 1992-02-28
Abstract: PURPOSE:To eliminate a noise component mixed in a sound signal from a microphone. CONSTITUTION:A microphone 1 is arranged close to a speaker and a microphone 2 is arranged close to a noise sourse. Then, since a noise is inputted to the microphone 1 delayed from the microphone 2, the delay time of a delay circuit 32 is set to a value adding the propagation delay of the noise and the delay of the delay circuit 31. Further, since the level of the noise inputted to the microphone 2 is higher than the level of the noise inputted to the microphone 1, a signal level is attenuated by a variable gain adjusting circuit 42 and the levels of the noise components in the outputs of the variable gain adjusting circuits 41, 42 are made to coincide. Thus, the noise components are inputted to a subtractor 5 with the same phase and with the same level and the noise components are canceled and only a sound signal is outputted from the subtractor 5. An echo canceler 6 operates in adaptive when temperature and humidity are changed further and cancels and eliminates the noise component perfectly.

Filed: 1990-02-23
Abstract: PURPOSE:To enhance the durability and coating properties of the title veneer by flaking log flitches, which are impregnated with resin for a WPC treatment and in which the resin is cured, to form wood flakes, applying an adhesive to the wood flakes, which are then compressed into a block to make formed flitches, and thereafter slicing the formed flitches. CONSTITUTION:Raw wood flitches 1 are first formed by cutting a log. After the raw wood flitches 1 are put into a treating vessel 5 to be impregnated with resin for a WPC treatment, the resin is cured. The raw wood flitches 1 are cut by a planer 11 to be flaked into the form of wood flakes 2, and an adhesive such as a urethane adhesive is applied to the wood flakes 2, which are then put into the form 8 of a pressing device 7 to be compressed and formed into formed flitches 3 by a top force 9. A plurality of the formed flitches 3 are assembled and, after an assembled flitch 10 is thus formed, it is sliced to form a woody decorative veneer 4. Since the wood flakes of the woody decorative veneer 4 have been subjected to the WPC treatment, the durability of the woody decorative veneer is enhanced, and its coating properties can also be enhanced while its water absorbability is suppressed.
