Abstract: PURPOSE:To enable stable turn-OFF by separating an auxiliary cathode electrode leading-out lead from a main cathode electrode leading-out lead and extracting the auxiliary cathode electrode leading-out lead directly from a cathode electrode for a semiconductor pellet or from a section in the vicinity of the cathode electrode. CONSTITUTION:Structure in which an auxiliary cathode lead is extracted directly from where adjacent to a cathode electrode for a semiconductor pellet 2 or the cathode electrode is formed. Consequently, wiring inductance LK1, LK2 do not function as the common inductance of load currents iL and gate currents iG, thus inhibiting the transient dropping phenomenon of gate currents. Strain inductance LG1, LG2, LKA1, LKA2 in a circuit through which gate currents iG flow get no trouble because they operate so as to reduce the dropping phenomenon. Accordingly, the turn-OFF operation is enabled safely and positively. Power loss generated in a gate circuit can also be minimized.

Title: Method for treating waste water containing ferrous ion
Inventor: EMA SHUNICHI
IPC: C02F1/64
Filed: 1987-08-31
Abstract: PURPOSE:To permit the formation of the ferrite with a better characteristics by recovering the ferrous hydroxide obtained at a pH of 9-11 as sediment with ferrite and coagulant added thereto and adding Fe<3+> ion thereto, so that Fe<3+>/Fe<2+> ions will attain a value of 1-2. CONSTITUTION:The surface of ferrous hydroxide maintained at a pH of 9-11 by the addition of an alkaline agent indicates a positive value and the surface thereof indicates a negative value when doped with ferrite in such proportions that the weight of the ferrite is not less than one time that of the ferrous hydroxide. For this reason, the adsorption of these constituents is easily conducted. Such mixture is then subjected to coagulation settling by the addition of a highly molecular coagulant so as to reduce the volume of the sediment. This ferrous hydroxide is thereafter mixed with ferric salt or ferric hydroxide, so that Fe<3+>/Fe<2+> ions will attain a value of 1-2 and, after being adjusted to alkaline pH side, this mixture is aged to form ferrite. By this process, the concentration of the Fe<2+> ion in the recovered sediment can be increased and a highly magnetized ferrite can be obtained from such sediment.

Abstract: PURPOSE:To obtain a heat sink whose thermal conductivity is high, which is firm and whose thermal stability is high by a method wherein a film of a group VIII metal in the periodic table is metallized on the surface of a sintered substance of cubic-system boron nitride (CBN) by a chemical vapor evaporation method. CONSTITUTION:A heat sink is constituted in such a way that a film of a group VIII metal in the periodic table such as Ni, Co, Ru, Rh, Pd, Os, Ir, Pt or the like is formed on the surface of a sintered substance of CBN by a chemical vapor evaporation method. Because the metal film of this heat sink is formed by a high-temperature CVD method, an adhesion force of the film to CBN as a base substance is much higher than that by a sputtering method, and CBN does not form an unstable compound together with the group VIII metal, the adhesion force is stable for a long time; thermal conductivity of a metallized layer is not low; thereby this heat sink can display its excellent performance.

Abstract: PURPOSE:To improve close contactness and reduce mask image by getting statistic contact of the center or its vicinity of mask and wafer and then close contact of the peripheral part through gradual increase of vacuum pressure between said wafer and mask. CONSTITUTION:A mask 4 and a wafer 6 are set and a vacuum leakage preventing member 8 are placed in contact with the lower part of a mask holder and thereby a vacuum chamber 9 is formed. The vacuum condition is supplied to the vacuum chamber 9 through a pipe 16, while gas through a pipe 15. A flow rate of gas is gradually reduced using a servo-driven valve 11 in order to smoothly change a vacuum pressure. A sensor 10 monitors a vacuum pressure of vacuum chamber 9 and feeds back data to a drive system 12 for driving the servodriven valve. Thereby, influence given on the vacuum pressure rising curve by disturbance can be eliminated. Through this process, the mask 4 and wafer 6 can be placed to close contact condition.

Filed: 1986-09-11
Abstract: PURPOSE:To easily convert a measured value to an electric signal, by calculating the dimension of the gap of an article to be measured as the function of the relative moving quantity of the first and second measuring elements. CONSTITUTION:In measuring a gap (x), the first measuring element 1 is inserted in the gap (x) until the edge 38 of the second region 39 contacts with the end part 41 of the first measuring element 1 while the side part 40 of the first measuring element 1 is brought into contact with the surface 36 of the first region 37. Due to this insertion, the second measuring element 2 is pushed in the gap (x) against the elasticity of an advancing spring while the end part 42 of said measuring element 2 contacts with the end edge 38 of the second region 39. When the end edge 38 is brought into contact with the end part 41 of the first measuring element 1, the push-in operation of the second measuring element 2 is finished. At this time, the displacement quantity of the second measuring element 2 has become (y). Therefore, the gap (x) is determined as x=y.tantheta.

Title: Spring holder
Inventor: AKIZUKI HIDEAKI
IPC: H05K3/30
Filed: 1996-08-15
Abstract: PROBLEM TO BE SOLVED: To provide a spring holder which holds an electric wire in such a state that the wire hardly comes off the holder, even when tension is given to the wire and has superior portability. SOLUTION: A spring holder 1 consists mainly of a coil spring 3, a main body section 5 which is passed through the spring 3 in the axial direction, and a fixing section 11 and a hook section 13 which are respectively provided at both end sections 7 and 9 of the section 5. The cross section of the shaft of the section 5 is enlarged to such an extent that the section 5 does not prevent the extension and contraction of the spring 3. Therefore, the spring 3 does not bend, even when tension is applied to an electric wire held with the holder 1. In addition, the spring 3 does not bent, because the spring 3 is not fixed directly to a printed wiring board A, but indirectly through the section 5.

For instance, a time interval request signal sent from either one of stations 2a-2d is smaller than hitherto T1 in the M-th data collection, in such a case, the station 1 detects the request signal and changes the time interval to T2. Then the (M+1)th data is collected.
