Title: Amplifier circuit
Inventor: OGAWA ATSUSHI
IPC: H03F3/45
Filed: 1983-01-21
Abstract: PURPOSE:To operate the titled amplifier circuit even if an input signal voltage is nearly zero voltage by providing an offset generating means giving a prescribed offset voltage to a base of a transistor (TR) of a differential amplifier circuit to which a negative feedback signal from an output is applied so as to drive possibly the amplifier by a single power supply of low voltage. CONSTITUTION:Sufficient negative feedback in terms of DC is applied to TRs Q11, Q12 and the operation is stable when each collector current is equal at no signal state. Since the emitter area of the TRQ12 is seven times that of the TRQ11, an offset voltage being V=VTXlnX7 50mV is produced to the base potential, where VT is a thermal voltage. Thus, in comparing the TRs Q11, Q12, the base potential of the TRQ12 is made higher than that of the TRQ11 by 50 mV. Thus, the differential amplifier circuit comprising the TRs Q11, Q12, does not require the base bias of a TRQqq, and even if a signal of a signal source 21 is nearly zero voltage, the TRQ2 is operated without saturation.

Title: Force control system for robot
Inventor: NISHIMOTO KATSUSHI
IPC: G05D3/12
Filed: 1990-01-19
Abstract: PURPOSE:To reduce the overshortness of force by using only the proportional control with a force control mode just before a robot comes into contact with a work object. CONSTITUTION:A robot 3 travels at the maximum speed passible by a position control means 4, to the position just before a work object, by way of example. A proportional element as a compensating element 2 in a force control means 5 is used till the detecting force of an inner force sensor 1 is reached to a steady state since it has reached the desired position. In consequence, compensation for control comes to a damping item, alone, so that force overshortness is almost nothing when the robot 3 comes into contact with the object. The detecting force of the inner force sensor 1 is increased to some extent, approximating to a force command value since the robot 3 has contacted with the work object, but it is only the proportional control so that there is a possibility of a steady deviation being produced. Accordingly, the compensating element 2 in the force control means 5 is set down to a proportional-integral element at a time when the detecting force of the sensor 1 is reached to the steady state, thus a solution of the steady deviation of force and a smooth variation are realized.

Title: Solenoid
Inventor: OKAMOTO ARATA
IPC: H01F7/13
Filed: 1979-01-31
Abstract: PURPOSE: To obtain a solenoid wherein the moving speed of the plunger is not accelerated beyond what is necessary in the process of attracting operation.  
     CONSTITUTION: The cylindrical plunger guide 30 made of non-magnetic material pierces through the upper plate 21, thick plates 25, 26 and bottom plate 22, and is fixed. The iron plunger 31 is slidably put into the guide 30, the exciting coil 32 is provided around the guide 30. The cover 33 made of non-magnetic material is attached to the lower face of the bottom plate 22 to close the lower side opening of the guide 30. When the volume of the chamber 34 varies with the movement of plunger 31, air flows through the gap between the plunger and the guide. In the initial stage of attraction, the magnetic attraction is considerably greater than the drag that acts on the plunger, so that the plunger is suddenly accelerated, and when it approaches to the terminal position, the drag exceeds the attraction, so that the plunger is decelerated and stopped when it comes in contact with the stopper 67. In this way, the acceleration beyond what is necessary can be prevented in the process of attracting operation.
