Title: Automatic gain control circuit
Inventor: SENBA TAKASHI
IPC: H03G3/30
Filed: 1988-08-30
Abstract: PURPOSE:To improve the accuracy and stability of an input voltage to a comparator for producing a gain control voltage by adding outputs of a differential amplifier circuit so as to obtain a reference voltage of a comparator. CONSTITUTION:A DC potential of an output signal of a differential amplifier circuit and a minimum potential detected from the amplitude of a signal at a high potential side are brought to the same potential, the stable state. When the amplitude of the input signal is decreased, the amplitude of signal waveforms 201, 202 is decreased, a reference voltage 203 is unchanged and the amplitude of signal waveforms 204, 205 is decreased, then the minimum level in the amplitude is increased, showing a difference from the reference potential 203. Then difference is outputted at an output terminal 120 by a comparator 118 as a gain control voltage. Thus, the reference voltage is given from the differential amplifier and the control accuracy is improved.

Title: Method and apparatus for drying matter to be dried
Inventor: OOSHIMA YUKITOYO
IPC: H01J9/38
Filed: 1996-08-16
Abstract: PROBLEM TO BE SOLVED: To dry water sticking to or contained in a matter to be dried in a very short without using a heat source by repeating pressurization by spraying compressed air to the matter to be dried through an air blowing means and the pressure reduction of air near the matter to be dried by an evacuating means for evacuating the air. SOLUTION: An electron gun 7 as a matter to be dried is inserted into a basket 6, a handle 19 is rotated to lower a ball screw 16 and the basket 6 is put in the water 5 of a water tank part 2 to clean the electron gun 7. When the basket 6 is raised and passed through a drying part 3 after cleaning the gun, compressed air is blown from nozzles 8L and 8R through a pipeline 24. Since the electron gun 7 in the basket 6 rotates, pressurizing force from the nozzles 8L and 8R are alternately applied to respective parts for a short time. Since air is always evacuated by a fan 11, pressure is reduced and the reduced pressure operates in the drying part 3, the pressurization and pressure reduction are repeated in a short time.

Title: Transmission use connector
Inventor: SUZUKI SATOSHI
IPC: H04L12/40
Filed: 1990-08-16
Abstract: PURPOSE:To send a signal without unbalancing impedance matching between a trunk line of a bus type transmission line and a signal reflection prevention member by branching a signal from the bus type transmission line to a communication equipment in the inside of the communication equipment. CONSTITUTION:When a signal is sent from a bus driver 12 of a node n1, power is divided into two by a transmission connector 14 and sent to a communication bus line 10. On the presumption of the bus type transmission line through which the signal is propagated with branching, branching is implemented in the transmission connector 14 to eliminate a block whose impedance is Z0 so as to eliminate a change in the impedance for signal transmission elapse time thereby making the impedance constant to be Z0/2. Then the reflection of the signal on the communication bus line 10 is surely prevented. Moreover, since the number of connection on the transmission line is reduced by using the connector 14, the reliability of the system and the workability in the manufacture of the transmission line are improved.

Title: Trim angle control device in ship propelling unit
Inventor: TAGUCHI MICHIHIRO
IPC: B63H20/10
Filed: 1985-10-02
Abstract: PURPOSE:To make possible to eliminate manual operation, by associating a mode changeover switch with an engine speed detecting means so that the control mode of an engine is automatically changed over into a manual mode when the speed of the engine is below a set value but into a preset mode when the speed exceeds the set value. CONSTITUTION:When the rotational speed of an engine is below a set speed, a mode change-over switch 70 is turned off, and therefore, a comparator does not issue a tilt-up stop signal. Accordingly, a manual mode is set so that a propelling unit 10 may be set to a desired trim angle in accordance with the manipulation of a trim switch 48, and therefore, a tilt-up operation is also possible. When the engine rotational speed raises, exceeding the set speed at a setting unit 82, the change-over switch 70 is turned on so that a preset mode is established. Therefore, the propelling unit 10 may be subjected to a tilt-down by means of the switch 48 when the propelling unit 10 is set exceeding a desired trim angle alpha at a setting unit 64, while it is tilted up when it is below the desired trim angle alpha, until the desired trim angle alpha is obtained. Accordingly, the propelling unit 10 comes to a stop automatically at this trim angle alpha.
