Title: Compensating circuit for output of semiconductor pressure sensor
Inventor: NAKANO ISAO
IPC: H03K17/94
Filed: 1983-04-20
Abstract: PURPOSE:To enable measurement of a slight change in atmospheric pressure without being affected by ambient temp. by providing a constant voltage power source to the input terminal of a bridge circuit constituted of pressure sensitive resistance elements provided to a semiconductor pressure sensor and a voltage generating circuit to the output terminal thereof. CONSTITUTION:The two input terminals of an amplifier 24 are connected respectively to output leads 9, 9' of a bridge, via an additive resistor 25 and a voltage generating circuit 27 at the one terminal and via an additive resistor 25 at the other terminal. The circuit 27 consists of a constant voltage power source and a voltage dividing resistor 29. The voltage between the two terminals 30 and 31 can be selected optionally by shifting the connecting position of the terminal 30 on the output lead 9 side. The voltage corresponding to the atmospheric pressure is kept outputted between the leads 9 and 9'. If the position of the terminal 30 is so adjusted as to generate the voltage corresponding to the atmospheric pressure between the terminals 30 and 31 in this state, the voltage between the two input terminals is made zero. If, therefore, the voltage between the leads 9 and 9' changes with a change in the condition of the atmospheric pressure, only the change component of the voltage is amplified by the amplifier 24 and a slight change in the atmospheric pressure is exactly measured.

Title: Method for controlling plate camber in reversible rolling mill
Inventor: KIMURA KAZUYOSHI
IPC: B21B37/00
Filed: 1988-03-24
Abstract: PURPOSE:To precisely prevent the plate camber by controlling the peripheral speeds ratio of upper and lower rolls on the last path according to the plate camber at the outlet side of the rolling mill estimated by the difference of the electric currents between upper and lower motors on one path before the last path of the rolling. CONSTITUTION:After a stock 1 to be rolled is bitten into the mill at the rolling on one path before the last path, the electric currents of motors 5, 6 of the upper and lower rolls are detected by electric current detectors 7, 8 respectively, the difference of the currents is computed by a subtracter 9. From this current difference, an estimated plate camber value is computed by a computing element 10 based on a proportional equation and the peripheral speed ratio of the upper and lower rolls required for preventing the plate camber is computed from a relational equation. This peripheral speed ratio is stored in a storage device 11, and at the last path, the peripheral speed difference of the rolls is computed from the stored peripheral speed ratio of the rolls, the speed of the roll driving motor 5 or 6 having larger electric current value than the other is reduced by a speed control device 12. By this method, the plate camber of the stock to be rolled is prevented and breakages of the installation and the decrease of the productivity are prevented.

Title: Flow controller for fluid
Inventor: DEIBUITSUTO GURASU
IPC: F22B1/06
Filed: 1989-03-22
Abstract: PURPOSE: To limit a fluid flowing through a tube by an arrangement wherein a fluid duct collapses in response to pressure difference between the interior and exterior thereof. CONSTITUTION: Each flow control device 34 has a shape of substantially tubular sleeve 34a coupled with the upper surface 16a of a tube plate 16 such that an associated tube 30 is opened through one sleeve 34a to an inlet header chamber 22 or an outlet header. Since the entire cross-sectional area of the tube 30 is smaller than the cross-sectional area of the chamber 22, velocity of water flowing therefrom into the device 34 increases. The device 34 is subjected to a larger pressure on the outer surface than on the inner surface. Upon rupture of a U-tube 30, total external pressure of respective devices increases significantly and the sleeve 34a begins to collapse inwardly.  Consequently, cross-sectional of the sleeve 34a decreases and the current velocity increases as the pressure increases to accelerate collapse thus interrupting the channel passing through the associated tube 30 completely at the opposite ends thereof.

Title: Analog-digital converting circuit
Inventor: SUDOU TOSHIO
IPC: H03M1/36
Filed: 1984-04-09
Abstract: PURPOSE:To decrease remarkably the number of voltage comparator circuits while the converting speed is slightly lower than that of the parallel comparison system by executing the AD conversion twice for a high-order half bit and a low-order half bit. CONSTITUTION:An input voltage e0 of an analog signal is decoded in response to the four states of e0>e4, e4>e0>e8, e8>e0>e12, e12>e0 by conducting switches 18-20 from a time TA to a TC and a decoded output of a decoder circuit 46 is latched to a latch circuit 47 at a time TB. Thus, the high-order bit as the result of AD conversion is obtained at output terminals 49, 50. After the time TC, any set of switches 21-23, 24-26, 27-29 and 30-32 is conducted based on the result of conversion of the high-order 2-bit. Thus, a digital signal obtained at an output of the decoder circuit 46 is latched to a latch circuit 48 at a time TD so as to obtain the lower-order 2-bit. Thus, although the converting speed is a little lower than that of the parallel comparison system, the number of voltage comparator circuits is decreased remarkably in this way.

Title: Liquid sealing type mount device
Inventor: KATO RENTARO
IPC: B60K5/12
Filed: 1995-03-29
Abstract: PURPOSE: To connect/disconnect an orifice passage surely and stably by exerting negative force on a working chamber, thereby sucking a pushing/pressing member toward the bottom wall part side of a lid member, thereby releasing the pushing/pressing force of the pushing/pressing member to a movable diaphragm, and thereby opening a communicating port of a first orifice passage. CONSTITUTION: When an air pipe body 98 is communicated with the atmosphere, elastic force of a coil spring 86 is exerted on a pushing/pressing metal fitting 84 so that a diaphragm 36 is pushed against an under plate metal fitting 52, thereby shutting off an inside orifice passage 64. When the air pipe body 98 is connected to a negative pressure source, the pushing/pressing metal fitting 84 is displaced to a bottom wall part (80) side of a lid metal fitting 76, resisting the energizing force of the coil spring 86, owing to the pressure difference between a working chamber 100 and a static pressure chamber 96.  As a result, since the pushing/pressing force against the diaphragm 36 is released, the diaphragm 36 is parted from the under plate metal fitting 52, and a communicating port 62 of the inside orifice passage 64 is connected to a balance chamber 46 via a small diameter, inverted-cup-shaped part 68.
