IPC: H05B41/231
Filed: 1992-09-09
Abstract: PURPOSE:To make momentary restarting property and wear reduction of discharge lamp electrode compatible by providing a control means for varying a power source voltage by a starting pulse generating power source according to the extinguishing time of a high voltage discharge lamp. CONSTITUTION:A predetermined time after switching in a lighting switch 10, a pulse generating relay 8 is conducted, and a high voltage is applied from a starting pulse generating high voltage power source 9 to the primary sides of pulse transformers PT1, PT2. The output voltage value of the power source 9 is varied according to the extinguishing time integrated by a time counter 11, and particularly varied so that it is linearly reduced 30 seconds after extinguished. According to this constitution, at the time of restarting just after extinguishing, a starting pulse with large energy is given to perform momentary restart, and at the time of restarting a certain time after extinguishing, arc transition can be performed with smaller energy to the extent of general start, and momentary restart and wear reduction of the electrode of a high voltage discharge lamp 6 can be made compatible.

Title: Method for supplying fuel to blast furnace tuyere
Inventor: KOUNO MASATO
IPC: C21B5/00
Filed: 1983-12-21
Abstract: PURPOSE:To enable use of general coal having grades over a wide range by mixing solid petroleum hydrocarbon contg. ash at a specific ratio or below with coal to adjust ash content, grinding the mixture thereof and supplying the fuel mixture of the pulverous powder having a prescribed ash content or below to a blast furnace tuyere. CONSTITUTION:General coal and caking coal are used for the pulverous coal to be blown to a blast furnace tuyere. The general coal has >=10% ash which exceeds 90% upper limit ash content of the fuel to be blown. It is a common practice to adjust such excessive ash content by using caking coal having a low ash content but there is a limit. Solid petroleum hydrocarbon having <=2% ash content is thereupon mixed with the general coal and the mixture is ground and is blown as the fuel mixture of the pulverous powder having <=9% ash content to the blast furnace tuyere. General coal having the higher ash content than heretofore is thus made usable.

Title: Wavy ring spring made of fiber reinforced composite material
Inventor: FUKUDA HIDEO
IPC: F16F1/34
Filed: 1987-09-26
Abstract: PURPOSE:To provide a spring which can be mass-produced and has a large effect of reducing the weight by forming the spring ring-shaped, which is made of fiber reinforced composite material where reinforced fibers are orientated in the circumferential direction in such a manner that the ring surface is a wavy form comprising a plurality of radial edge portions and trough portions. CONSTITUTION:A spring element of a wavy ring spring is formed in a wave form having a spring body 1, an edge portion 2, a trough portion 3 and the inner peripheral end 4 and outer peripheral end 5 of a ring using fiber reinforced composite material. When a coil spring receives load, the element wire is mainly subjected to torsional load. On the contrary, in case of this wavy ring spring, bending load is applied so that reinforced fiber may be orientated in the circumferential direction of the ring. Accordingly, the above wavy spring can be very simply formed by a filament winding method or a compression molding method.

Filed: 1985-10-25
Abstract: PURPOSE:To contrive a higher printing speed, by a construction wherein a contact part of a plunger the normal position of which is restricted and a contact part of a rear frame are conically shaped in a male-female relationship, and the contact parts perform a sliding action before the plunger reaches the normal position thereof. CONSTITUTION:At the center of an end face on the second yoke side 17 of a cylindrical part 19a of a rear frame 19, a conical contact part 19d is provided in a male-female relationship with a contact part 23d of a plunger 12, whereby the normal position of the plunger 1 is restricted. The contact parts 23d, 19d thus shaped perform a sliding action before the plunger 12 reaches the normal position thereof. Since the weight of the rear frame 19 has an effect on the reduction of the secondary bound of the plunger 12, it is set to be approximately equal to or greater than the weight of the plunger 12. Accordingly, since the secondary bound of the plunger 12 can be greatly reduced, a printing operation can be performed at a higher speed.
