Title: Needle pin and production thereof
Inventor: MIZOGAMI SHINICHI
IPC: C21D1/18
Filed: 1987-07-30
Abstract: PURPOSE:To obtain a superior needle pin enhanced in wear resistance and free from deformation, by a method wherein, in the pin of a high-speed steel, the hardness of the pin body part and tip end part, together with the shearing strength of the pin are specified. CONSTITUTION:A hardening treatment is applied overall to the pin of a high- speed steel at a normal hardening temperature, and the tip end part of the pin is heated and hardened for a short time at a temperature 50-200 deg.C higher than the aforesaid hardening temperature without being tempered. Thereafter, the pin is tempered overall. In the needle pin, its body part is Hv 850-950 in hardness and the tip end part is Hv 1000 or more in hardness and 400kg/mm<2> or more in shearing strength. Additionally, with a hardening temperature lower than the aforesaid to be applied to the tip end part of the pin, the components of an alloy carbide fail to dissolve into a matrix and the effect of the hardening cannot be obtained; on the other hand with a higher hardening temperature, particles become coarse to deteriorate the toughness. Namely, the tip end part of the pin is desirably hardened at a temperature of 1250-1400 deg.C.

Title: Mass spectrometer
Inventor: AKAMATSU NAOTOSHI
IPC: G01N27/62
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To reduce a focusing diameter through the application of a laser beam from the vertical direction and to enhance image resolution by opposing a microscope to a sample, and causing ions to fly crosswise by means of ion accelerating electrodes. SOLUTION: A sample 2 is inserted between accelerating electrodes 22. During mass spectrometry, a laser beam 7a from a laser beam source 6 is focused onto the sample 2 by a condensing lens 22. An ion beam 21b excited thereby is accelerated by an accelerating electrode 40 in an almost perpendicular direction to the direction of incidence of the laser beam and is made to impinge on a mass spectrometer part 1. The ion beam 21b is reflected by an ion reflector 30 and impinges on an ion detecting part 34. Ion flight time can be obtained by measuring the time from the application of the laser beam 7b to the arrival of the ions at the ion detector 34. Mass spectrometry of the ions can thus be performed. During observation of the sample, light from a sample illuminating light source 8 is made to impinge on the sample 2 from the condensing lens 22.  An image of the sample 2 formed thereby is observed with a TV camera 10.

IPC: C25D3/02
Filed: 1982-11-02
Abstract: PURPOSE:To perform excellent plating while inhibiting the accumulation of multivalent ions, by performing said plating while reducing more multivalent metal ions in a plating solution with hydrogen activated by a hydrogen-occlusion alloy. CONSTITUTION:In performing plating using a plating bath containing metal ions such as Fe<2+> and Mn<2+>, more multivalent metal ions such as Fe<3+> and Mn<7+> formed in the plating bath are reduced with hydrogen activated by a hydrogen- occlusion alloy. As said hydrogen-occlusion alloy, Mg2Ni, FeTi, LaNi3, etc. may be used for instance.

Title: Moving image display device
Inventor: NAKANO MICHIO
IPC: H04N7/01
Filed: 1989-07-27
Abstract: PURPOSE:To hardly generate an after-image even when an object is speedily moved by executing averaging processing with the number of frames larger than the normal number of frames. CONSTITUTION:A television camera 1 generates a picture signal by a scanning signal to be supplied from a scanning signal generating part 2 and the number of frames per unit time in the picture signal, however, is set to a value larger than 30 frames per second as the number of frames in a normal television system, for example, set to 120 frames per second. The averaging processing is executed to an output signal outputted from the television camera 1 by an averaging processing part 3. Thus, since the averaging processing is executed in a state that the number of frames is large, the averaging processing is executed in the state of slow motion as a result even in the case of a picture to be speedily moved. Then, the after-image is hardly generated.

Abstract: PURPOSE:To improve the light emitting efficiency of the titled diode by a method wherein the first n-layer with the impurity concentration almost similar to that of a substrate, the second n-layer with the impurity concentration lower than that of the first layer by one figure or more and less thickness and a p-layer formed on the second layer are provided on a substrate. CONSTITUTION:An n type gallium phosphorus substrate 1 with impurity concentration of 1-3X10<17>cm<-3> is contained in a carbon boat together with melt in hydrogen atmosphere at high temperature (11). At this time, after mixing hydrogen sulfide within the hydrogen atmosphere for about one minute and introducing sulfur to be the main donor impurity into the melt the melt is cooled down to epitaxially grow the first n- layer 12. At this time, the impurity concentration of the first n-layer 2 30-50mum thick is almost similar to that of substrate 1 i.e. 1-5X10<17>cm<-3>. Then the melt is left for a long time (13). Finally the atmosphere converted from hydrogen to argon is cooled down after nitrogen is dissipated to epitaxially grow the second n-layer 14. The second n-layer 4 with the impurity concentration of 0.5-5X10<16>cm<-3> is 10-20mum thick. Then zinc vapor is successively introduced to liquid epitaxially grow a layer with impurity concentration of 5-10X10<18>cm<-5>.

Title: Method for adjusting frequency of dielectric coaxial resonator
Inventor: SENBA TSUKASA
IPC: H03B5/18
Filed: 1987-07-31
Abstract: PURPOSE:To adjust the resonance frequency of a dielectric coaxial resonator by trimming an electrode connected to the inner conductor of the dielectric coaxial resonator to change the inductance component on the load side to the coaxial resonator. CONSTITUTION:The front end of a coupling rod 6 electrically connected to the inner conductor (omitted in the figure) of a dielectric coaxial resonator 3 is electrically connected to a land 7 for connection. Coupling capacitors 2 and 4 are electrically connected to both ends of the land 7 for connection. Since the dielectric coaxial resonator 3 is relatively larger than coupling capacitors 2 and 4, the land 7 for connection is formed to have a relatively large area. According as the area of the land 7 for connection is larger, the inductance component based on this land 7 is reduced. Consequently, the resonance frequency is raised. The land 7 for connection is trimmed, and the length of the land 7 for connection is extended to adjust the resonance frequency to a lower value.

Filed: 1982-11-02
Abstract: PURPOSE:To obtain color temperature which is harmonious with an incandescent lamp or the like by specifying the relationship between the area of the cross section of a metal foil conductor at the electrode-sealing part and the electric power of a lamp as well as the relationship between the distance between the inner ends of the emission tube and its whole length. CONSTITUTION:In a metal halide lamp the internal volume of the emission tube of which is below 1c.c, the area (Smm.<2>) of the cross section of a molybdenum foil conductor 4 at the sealing part 2 of an electrode 3 is adjusted to 0.1XP<=S<= 0.4XP+4 relative to the electric power (P wat) of the lamp. In addition, the ratio (M/L) of the distance (M) between the inner ends of the emission tube to its whole length (L) is restricted to 3.5X10<-1M/L<4.7X10<-1>. As a result, loss caused by the thermal conduction of the sealing part 2 is reduced without deteriorating the sealing function of the molybdenum foil 4 thereby increasing the temperature of the coldest part. Consequently, the color temperature of such a lamp can be made almost equal to that of a fluorescent lamp. Besides, such a lamp can be used in substitution for or in combination with a fluorescent lamp.
