Title: Method of optical device recovery
Inventor: KIYASURIIN REJIINA AARII
IPC: G03F1/72
Filed: 1994-01-05
Abstract: PURPOSE: To remove the multilayered coatings of an optical element by a single stage while maintaining its reflectivity. CONSTITUTION: This optical element consist of a substrate 10 having a main surface and the multilayered coatings 60 on the main surface. The multilayered coatings alternately include a plurality of first material layers and at least second material layer. The restoration of the optical element having peak reflectivity at an X-ray wavelength is executed by removing the first multilayered coatings 60 from the substrate, then forming the second multilayered coatings having nearly the same compsn. and structure as the first multilayered coatings 60 so as to cover the main surface. The removal of the first multilayered coatings 60 is executed by dissolving the greater part of the first multilayered coatings 60 in a single etching soln., thereby nearly completely removing the first multilayered coatings 60 with the single etching step.  The formation of the second multilayered coatings is so executed that the restored optical element obtd. as a result exhibits the peak reflectivity of at least 80% of the max. value of the peak reflectivity that the optical element originally exhibited thus far.

Title: Cable guided underwater work boat
Inventor: KOMORI YUKINORI
IPC: B63C11/34
Filed: 1979-02-05
Abstract: PURPOSE: To improve the movement and working capacity of work boat by decreasing the weight of the under water cable in the vicinity of the boat, by sending gas to the float which has the variable buoyancy by being made as free for either expansion of contraction and attached to the cable connecting the work boat and the mother ship.  
     CONSTITUTION: When the work boat 4 is submerged below the mother ship 2, the work boat 4 is submerged by being suspended and by contracting the variable buoyancy float 5, 5 attached to the cable in the vicinity of the work boat. When the work boat reached the predetermined depth, as directed by the mother boat, gas is sent to the variable buoyancy tank 5, 5 through the flexible gas pipe 7 to expand the variable buoyancy tank 5, 5. The buoyancy is generated as soon as the variable buoyancy tank 5, 5 is expanded reducing the under water weight of the cable 1 in the vicinity of the work boat 4 to nearly about zero, thus capable of obtaining favourable characteristics for the movement and working capacity of the work boat 4.

Title: Heat fixing roll
Inventor: TSUKUDA YASUO
IPC: H05B3/00
Filed: 1983-01-29
Abstract: PURPOSE:To offset a generated magnetic field and suppress influence upon magnetic powder, and to improve the quality of a copied picture by flowing back a current which flows from one end of resistance films formed into a successive double layer in a roll-axis direction at the other end. CONSTITUTION:An insulating film 8 and resistance films 2 and 7 on both sides of an insulating film 4 are formed around a roll 9. The resistance films 2 and 7 succeed through a resistance film 3, and the current from an electrode 6 flows from one end of the resistance film 2 in the roll-axis direction and is returned by the resistance film 2 to flow to an electrode 5 in the original direction. Therefore, a magnetic field produced by the resistance film 7 is canceled by a magnetic field produced by the resistance film 2, so no magnetic field is established apparently. Thus, no influence of magnetic fields is exerted upon the behavior of magnetic powder for copying, so that a sharp copied picture is obtained.

Abstract: PURPOSE: To provide a small sized device not giving effect on the communication of a communication station using a signal line even when a transistor(TR) for the power supply for bus is faulty by supplying a bus current to the signal line connecting a current sensing resistor in series thereto. CONSTITUTION: A supply current IDC corresponding to a reference potential Vref at a terminal (e) is fed to a signal line L1 via current detection resistors R12, R22 in a steady state. A voltage signal corresponding to the current IDC is fed back to a feedback capacitor C21 as a potential difference ΔVab between terminals a, b of a voltage current converter 40 with respect to the resistor R12. Similarly the voltage signal corresponding to the current IDC is fed back to the feedback capacitor C21 as a potential difference ΔVgh between terminals g, h of a voltage current converter 70 with respect to the resistor R22. Thus, the potential at the terminal a, g is maintained without a change, and when TRs Q11, Q21 are not faulty, the Q21 is always in ON state and in the standby state. Through the constitution above, when a short-circuit fault takes place in the Q11, the Q21 is effectively operated and no effect is caused on communication between the signal lines L1, L2.

Title: Semiconductor device and its manufacture
Inventor: KOTAKE YOSHINORI
IPC: H01L27/088
Filed: 1994-02-04
Abstract: PURPOSE:To prevent the deterioration of electric characteristics like punch through, while the threshold voltage of an MIS type semiconductor element in a semiconductor device is lowered. CONSTITUTION:In a semiconductor device, the concentration of activation impurities in the channel of a low threshold voltage semiconductor element formed in a first active region ReA surrounded by an element isolation region 2 is set lower than the impurity concentration corresponding with an ordinary threshold value. A ring type gate electrode 16 is formed in the first active region ReA. In virtue of the formation of low concentration channel and the long channel width because of the ring type gate electrode 16, a semiconductor element having a threshold value very lower than the ordinary threshold value can be obtained. Hence, in the low threshold voltage semiconductor element, punch through is not generated and an OFF leak current is not increased when the channel length is reduced, and the threshold voltage is lowered. In particular, the effect is large when an ordinary threshold voltage semiconductor and a low threshold voltage semiconductor element are mounted on a semiconductor device.
