Title: Temperature detection circuit
Inventor: MIZUIDE YASUO
IPC: H01L21/8222
Filed: 1987-03-31
Abstract: PURPOSE:To obtain stable temp. detection characteristics by reducing the number of elements to be used and current consumption, by reversing the magnitude relation between the currents of the first and second transistors at predetermined temp. and detecting the reversal of the direction of the current of an output node. CONSTITUTION:In a temp. detection circuit 1, base bias is applied to transistors Q1, Q2 to allow currents I1, I2 to flow and the sum of both currents is equal to the constant current I0 of a constant current source 4. In this case, the current equal to the current I2 of Q2 flows to Q2 of a current mirror circuit 6 and the difference current IE of the currents I2, I1 flows in and flows out from an output node 7. Since the current I2 of Q2 has a negative temp. coefficient in temp. change, the current of Q1 also has negative temp. coefficient. Therefore, since the magnitude relation between the currents of Q1, Q2 reverses at a certain temp. point P, if a plan is made so as to generate reversal at a desired temp. point to be detected, the direction of the current IE of the node 7 reverses at this temp. point and temp. can be detected with high accuracy.

Title: Preventing method of camber at preceding end in rolling with dissimilar diameter rolls
Inventor: ITAZURI YASUHIRO
IPC: B21B45/02
Filed: 1982-05-07
Abstract: PURPOSE:To decrease the camber at the preceding end of a rolled material by rolling with dissimilar diameter rolls by lubricating highly the corresponding part on the outside of the rolled material where the camber is generated by the rolling with dissimilar diameter rolls. CONSTITUTION:There is a tendency toward cambering of the top of a rolled material at high curvature in rolling with dissimilar diameter rolls using an upper work roll 2 of a small diameter and a lower work roll 3 of a large diaeeter. The surface in the top part corresponding to the outside of the camber of the material 1 prior to rolling is lubricated selectively so as to be lubricated more highly than the other surface. The surface roughness of the roll 2 in such rolling mill is set larger than the surface roughness of the roll 2, and the camber at the preceding end of the material 1 is prevented by the difference in roughness and the same is further compensated with the difference in the lubrication on both surfaces of the rolled material.

Title: Ventilating device
IPC: F24F7/013
Filed: 1992-03-31
Abstract: PURPOSE:To reduce the term of works to mount a ventilating fan, to reduce a cost required for the mounting work, and to reduce a cost of parts and materials through integral formation of members. CONSTITUTION:A first cylinder part 6 integrally formed by using a ventilating port member and a second cylinder part 8 having an large inside diameter are integrally formed by means of an enlarging member 8B to form a body cylinder part 3. A fixing frame 9 to adjust axial movement of the body cylinder part is joined in a screwed-in state with the body cylinder part 3 and mounted on an outer wall bed material 33 by using the flange of the fixing frame. The work can be executed simultaneously with an indoor wiring work during completion of an outer wall work and a term of works for the work is reduced to an intensive value. Meanwhile, at a point of time when an interior work is all completed, an opening 2 is formed on the room interior 16 side. Even when a work is executed such that a center is slightly displaced at this point of time, the work is facilitated since the inside diameter of the second cylinder part 8 is larger than the size of the opening 2.

Title: Servo controller
Inventor: TAKEUCHI TOMOYOSHI
IPC: G05D3/12
Filed: 1987-03-30
Abstract: PURPOSE:To realize the stop control with high accuracy for a servo controller by calculating a command speed in a driving state via a CPU in accordance with a speed command to drive a DC motor under the speed feedback control and converting the position deviation into a speed command for execution of the stop control after the command speed is approximately equal to said position deviation. CONSTITUTION:A CPU 10 calculates a command speed based on a speed command in a driving state and a DC motor 15 is driven under the speed feedback control. Then the stop control is carried out based on the speed command value as well as the position deviation calculated from the position command value and the present position after the command speed is approximately equal to the position deviation. In other words, only a speed control loop is used for the stop control in a state where the motor 15 is driven by the speed command. Therefore the large gain is secured as shown by a curve A and the rise characteristics can be improved. The speed control loop is switched to a position control loop in a stop control state. In such a way, the highly accurate stop control is secured.

Abstract: PURPOSE:To execute distortion compensation in an amplitude direction and a phase direction independently respectively without mutual effect. CONSTITUTION:A distortion generating section 1 outputs an inverse distortion component to a distortion component produced at a power amplifier stage of the TV transmitter when a luminance level of an input video signal Si is a predetermined or higher level.

Title: Method of detecting fault of tool in machine tool
Inventor: KATOU YOSHINDO
IPC: B23Q17/09
Filed: 1978-06-28
Abstract: PURPOSE:To detect any fault of a tool by the continuous rise of an armature current of a DC motor for driving a supply device, thereby to detect the fault in the tool accurately and with a high reliability without using any specific senser or jig. CONSTITUTION:In a case where a tool 5 is normal, the armature current of a DC motor 10 is small, and a voltage generated at a resistor 23 is also small. Hence, a high level signal is not generated from a comparator 25, and even when a signal is generated on some reason or other, a tool fault signal is not produced from a time limit circuit 27 because the time of the signal generated is extremely small. In a case where a fault, that is, a damage or an excessive wear occurs, a working resistance increases, and the feed resistance of a slide 6 increases, and hence the load of a motor 10 becomes large and the armature current becomes continuously large. For this reason, the output of the comparator 25 assumes continuously a high level, and a tool fault signal is produced as output from the time limit circuit 27, thus a fault alarm sender 28 being operated.
