Abstract: PURPOSE:To improve recovering efficiency of Hg and to prevent discharge of Hg to the outside of the system by closing tightly a Hg recovering device and feeding exhaust gas in the Hg recovering device to waste water again. CONSTITUTION:Waste cooling water for a cooling tower 3 of an incineration furnace 1 is heated by a Hg evaporator 6 to evaporate Hg in the waste water 5. Evaporated Hg vapor 8 is cooled in a cooler 9 to condense to liquid Hg, and obtd. liquid Hg is recovered in a Hg recovering device 12. In this recovering process of Hg from waste water of an incineration furnace, the Hg recovering device 12 is closed tightly and the waste gas 13 in the Hg recovering device 12 is fed again to the waste water from the Hg evaporator 6. By this process, the recovering efficiency for Hg is improved and discharge of Hg to outside of the system is prevented.

Title: Image forming apparatus
Inventor: TANIGUCHI KEITARO
IPC: B65H43/04
Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To prevent image output of an output prohibited image without applying large alteration to a system in an image forming apparatus having an output head. SOLUTION: In an image forming apparatus, paper 30 is fed by the rotation of a pair of feed rollers 21a, 21b. A feed motor 22 is reversibly rotatable and can move paper so as to allow the same to retreat in a reverse direction. In usual printing, paper is fed and a printing head 24 is reciprocally moved to form an image on the paper. An image recognizing part 18 judges whether the formed image is an output prohibited image and, in the case of the prohibited image, the motor is reversed to allow the paper to retreat and the printing head outputs a predetermined color to apply printing to the paper. By this constitution, the already printed output prohibited image can be painted out by the predetermined color.  Output prohibiting function is provided to the printing head and only the motor is made reversibly rotatable to make it almost unnecessary to alter fundamental printing algorithm in a normal state.

Title: Hot rolling method
Inventor: NOMA YOSHINOSUKE
IPC: B21B37/00
Filed: 1980-08-28
Abstract: PURPOSE: To forcibly feed the tip of a material into an edging roll, to prevent generation of an edge drop, and to improve the yield of the edging pass, by slowing down the circumferential speed of the edging roll on the run-out side of a horizontal mill when the material is bitten by the edging roll, and by making the circumferential speed of the edging roll after biting the material synchronize with the speed of the material.  
     CONSTITUTION: The circumferential speed VE of an edging roll 1 is set by equation I. In which, VH is the circumferential speed of a horizontal mill roll 2, (f) is the forward slip of the horizontal mill roll 2, and α is a control factor. The smaller the value of α is, the smaller the value of VE is; and this makes the edge drop effect large, and worsens the threadability of the material. At a stage of biting a material by the edging roll 1, α=0.5 is set; according to the detected variation of the electric current caused by feeding the material into the edging roll 1, the value of α is increased to a final value α=1.0 by which the circumferential speed VE of the edging roll 1 synchronizes with the material speed (1+f)VH on the run-out side of the horizontal mill roll 2; then, only the tip of the material is forcibly fed to the edging roll 1 by the horizontal roll, so that the edge drop in the tip of the material is prevented.

Title: Inspecting device for optical system
Inventor: ENDO TAISUKE
IPC: G01M11/02
Filed: 1985-05-31
Abstract: PURPOSE:To improve measurement precision by arranging a linear slit so that the direction of the groove coincides with the direction of a grating, and emitting impulsive illumination light periodically while moving the slit on the surface of the grating at an equal speed at right angles to the groove. CONSTITUTION:The rays of light from a spot light source 1 are passed through a chopper 7 and collimated by a collimator lens 2 into parallel light to illuminate a lens 3 to be inspected and the rays of light passed through this lens 3 are projected on a screen 4 through the slit 4. Then, the slit is shifted in position by (d) and the light passed through the slit 4 is projected on the screen 5 similarly. The chopper 7 is driven with a synchronizing signal from a slit moving device so as to cut off the light in the middle of the movement of the slit 4. This operation is repeated at every time the slit 4 is shifted in position by (d) to obtain a Ronchi-gram equivalent to that obtained by using a Ronchi grating which has grating intervals (d) and 1/(VT) fringes per unit length, thereby improving measurement precision.

Title: Semiconductor laser diode control device
Inventor: HOSHINO TAKASHI
IPC: H01S5/068
Filed: 1990-05-08
Abstract: PURPOSE:To prevent overshooting when power is turned on and obtain an inexpensive control device which is superb in temperature characteristics by providing a delay element for delaying start-up of a drive power of a laser diode at a signal output circuit of a transistor for comparison and amplification. CONSTITUTION:Immediately after a power is turned on, a base current rapidly flows to a transistor for comparison and amplification 16, thus resulting in saturation region, and a collector current is limited by a delay element consisting of a current-limiting resistor 21, thus causing start-up of a transistor for power amplification 14 to be delayed due to a delay circuit which consists of the current-limiting resistor 21 and a capacitor for compensating phase 15 and preventing a rapid current to flow into the circuit. As a result, even if indicial response of the circuit is vibrating within a certain range, no overshoot appears since input signal is not in step shape, thus preventing an excessive current to flow into a laser diode 11.

Title: Fine adjustment mechanism calibrating device using piezoelectric element
Inventor: FUKUCHI YASUHIKO
IPC: G05D3/00
Filed: 1990-05-08
Abstract: PURPOSE:To attain a highly accurate positioning job at the time of actually measuring by producing and using the correction data on the nonlinear properties, etc., in a fine adjustment mechanism using a piezoelectric element that can perform the superfine positioning jobs of a scan type tunnel microscope. CONSTITUTION:A correction sample 2 is put on a fine adjustment mechanism 1, and the position data are given to the mechanism 1 from a fine adjustment control circuit 4. Then the sample 2 is finely moved. At the same time, a probe 5 is relatively moved onto the surface of the sample 2 with the operation of a scan type tunnel microscope STM and a tunnel current is outputted. This tunnel current is detected by a detection circuit 6 and a probe control circuit 9 controls the height of the probe 5 so as to keep the tunnel current at a constant level. The position information on the probe 5 is fetched by a correction data calculation/storage device 10 from the circuit 9 in regard of the height direction of the probe 5. Then the device 10 compares the position data given to the mechanism 1 from the circuit 4 with the actual shift data on the sample 2 on the basis of the known surface structure of the sample 2. Thus the calibrating data can be obtained for the characteristic of the mechanism 1 and used for measurement of the STM.
