Filed: 1990-07-06
Abstract: PURPOSE:To form heat resistant mixed thermal-spraying coated layer available in ultra high temp. and in an atmosphere with large temp. difference by symmetrically arranging plural powder charging holes to one thermal spraying gun and executing the thermal spraying. CONSTITUTION:In the case of executing the thermal spraying of (m) kinds (m>=2) of powders with one thermal spraying gun 1 at the same time, same kind of powder is jetted by supplying a same kind of powder through n Xpowder charging holes provided at the (n) symmetrical positions (n>=2), wherein the symmetrical axes are based on a cathode 2 as the center, and the thermal spraying is executed. For example, four charging holes are symmetrically set to the cathode (tungsten electrode) 2. Ceramic powder is charged from the faced charging holes Pa and Pc, and metal powder is charged from the charging holes Pb, Pd, and at the same time, the thermal spraying is executed. A uniformly mixed layer is obtd. over the whole zone of thermal spraying layer without developing disturbance of shape to the plasma jet. By this method, the ultra heat-resistant film for preventing the film from breakage and boundary detachment under ultrahigh temp. as well as large temp. difference atmosphere, can be formed.

Title: Supporting structure for reflection mirror spider
Inventor: MIKAMI IZUMI
IPC: G02B7/00
Filed: 1987-07-15
Abstract: PURPOSE:To reduce a radiant ratio and to obtain a high S/N, by constituting a plane confronting with a main reflection mirror in a reflection mirror spider supporting structure of a material having a high reflectance in an infrared ray area. CONSTITUTION:The plane 6a' confronting with the main reflection mirror 2 of a spider 6 is constituted of the material having the high reflectance in the infrared ray area. The plane 6' is set as the grinding plane made of Al, and a ray outputted perpendicularly from the plane 6' confronting with the main reflection mirror 2 of the spider 6 is emitted to a room via the main reflection mirror 2. Since relation between the reflectance gamma and the radiant ratio epsilon is set as gamma+epsilon=1, it is possible to reduce the radiant ratio of noise infrared ray by increasing the reflectance gamma forming the plane 6' of the spider 6 with a mirror of Al. Thus, it results that an input signal to a measuring instrument = (the signal 8 of a celestial body to be measured) + (the noise infrared ray 10 emitted from the spider 6 with a low radiant ratio), then, the noise in the measuring instrument can be reduced.

Title: Displacer in refrigerating machine
Inventor: YASUKAWA YUKIO
IPC: F25B9/14
Filed: 1988-07-18
Abstract: PURPOSE:To use a nonlinear restoring force to increase the refrigeration capacity of a displacer in a refrigerating machine by setting magnetic poles in the directions of the reciprocating motion of the displacer in such a manner as to bring like poles to face each other between each of magnets fixed inside a cylinder and each of magnets fixed outside the displacer. CONSTITUTION:On the cylinder axis extending in the directions of the reciprocating motion of a displacer 3a magnets 21 and 24 are fixed respectively to the end of a cylinder 5a on the cooling side 4 and on the other end on the side of a casing 13 in such a manner as to bring like poles to face each other between these magnets and magnets 22 and 23. When the displacer 3a goes from the neutral position to the upper dead point, it reaches a position near the upper dead point more quickly than a sine-wave change because of insufficiency of the restoring force in the early stage. The restoring force increases pronouncedly, slowing down the motion, at the positions close to the upper dead point. On its way from the upper dead point to the neutral position the displacer 3a does not return quickly initially, but does quickly as the restoring force begins to be enervated. The same tendency acts inversely when the displacer moves from the neutral point to the lower dead center, so that the work of refrigeration increases as seen from a wave form of the expansion chamber pressure bulging over and below the sine wave.

Title: Semiconductor device
Inventor: FURUHATA SHOICHI
IPC: H01L25/00
Filed: 1990-07-06
Abstract: PURPOSE:To prevent oscillation phenomena and irregularities of switching response time, by connecting a specified resistor about the chip area of an element, between a driving terminal formed outside a package and a driving electrode of the element, and accommodating said resistor in the package. CONSTITUTION:The time constant of switching of a switching element is determined by the product of the capacitance between driving terminals of the element and the resistor connected in series with the electrode of the element. Hence, when a resistor inversely proportional to the chip area determining the capacitance between driving terminals is connected between the driving electrode and the driving terminal of the element, the switching time is set in a specified range, without connecting a resistor outside the driving terminal. The chip area is smaller than or equal to several cm<2>, and the largest area is about 10cm<2>, so that the value of 10-50/AOMEGA (where A is the chip area of the element in cm<2>) becomes larger than or equal to 1OMEGA, and oscillation phenomena at the time of switching operation can be prevented by the effect of resistor. For example, in each of the modules 21, 22, resistors 41, 42 are connected between gate electrodes of IGBT 11, 12 and gate terminals G. The resistance values of the resistors 41, 42 are determined by the chip sizes of the IGBT's.

Title: On-load tap changer
Inventor: IMAI MITSUO
IPC: H01F29/04
Filed: 1990-07-04
Abstract: PURPOSE:To determine the time of exchange with high accuracy by obtaining currents flowing through each arc contact from an output from a detecting section, arithmetically operating the consumption of each arc contact by calculating formula held at the time of normal operation, and comparing the arithmetic value and allowable consumption. CONSTITUTION:The closing time of a contact B is delayed by the consumption of a contact B. The delay is shown by gamma in the figure at the angle of rotation of a movable section. Since a contact A is contact-parted by closing the contact B, the contact-parting time of the contact A is also delayed with the delay of the closing of the contact B when the closing of the contact B is retarded. Consequently, time allowance up to the closing of a contact C is reduced to the duration of an arc generated by the contact-parting of the contact A, thus increasing the possibility of short circuits among taps. Accordingly, a second arithmetic section 11 compares consumption at every contact as well as the difference of consumption among each contact with each allowance value, and outputs the number of changeover until each consumption reaches the allowance values as the time of exchange on the basis of the integrated value of the number of tap changeover up to that time.
