Title: Burner for high load, low oxygen concentration
Inventor: KIKUTANI FUMITAKA
IPC: F23D14/08
Filed: 1984-11-16
Abstract: PURPOSE:To realize high load combustion by a method wherein a recess portion having a tip end section which the tip is bent sharply at the both side thereof, is formed along the longitudinal direction of a flame port portion and the many flame ports of a slit type or round hole type are arranged. CONSTITUTION:Fuel, injected from a nozzle toward the primary air port 1 at high speed, absorbs the primary air by ejector effect, becomes mixture at a mixing pipe 2 while it is adjusted to the uniform flow velocity at an equalization portion 3 and is supplied to the flame port section 4. Premixture is injected from a flame port 7 along an inner wall due to the sharp bending of the tip end section 6, and a fish tail flame (a) is formed. The flame is separated to large two parts due to the two tip ends 6 and the fish tail flame is formed, therefore, the secondary air is supplied enough, even when the amount of the combustion is increased, the flame length does not become large. According to this method, the high load combustion may be achieved.

Abstract: PURPOSE:To facilitate assembly and to contrive a cost reduction as well by forming 1st and 2nd fixing plates and 1st and 2nd revolving shafts of parts respectively having the same shapes. CONSTITUTION:A middle lens barrel 1 is moved forward and backward in order to focus the lens, but two pieces of lock bolts 9 are engaged with cam holes 3a, 3b of an outer lens barrel 3 and, therefore, the middle lens barrel 1 turns along the cam holes 3a, 3b and move in an optical axis direction in conformity with the curves of the cam. The same holds true of a front lens barrel 2. The outer lens barrel 3 and the middle lens barrel 1 as well as the front lens barrel 2 and the middle lens barrel 1 clatter less in the fitting parts and are, therefore, free from the inclination of the optical axis. The bolts 9 are turned to the last upon ending of the focusing. Lock nuts 10 are then raised and the outer wall of the outer lens barrel 3 is fastened by means of the bolts 9 and the nuts 10 to prevent the middle lens barrel 1 from moving on the side where a spacer 11 is inserted. The bolt 9 engages with the cam hole 3b and acts as the guide for sliding and rotating on the side where the spacer 11 is not inserted. While the nuts 10 and the bolts 9 of the same parts are used at the top and bottom of the centrally split middle lens barrel 1, one thereof plays the role of stopping the rotation and the other the role of a guide.

IPC: G06F3/06
Filed: 1988-09-29
Abstract: PURPOSE:To guarantee the safety of data and to improve the performance by putting >=2 disk drives in parallel operation and doubling files with the same performance with one drive. CONSTITUTION:When a file store (write) instruction is sent to a microprocessor(MPU) through a communication controller(CCU) 3, the MPU writes a file on hard disk drives(HDD) 5 and 6 from a main storage device(MMU) 2 through a system bus 4. In this disk writing operation, the controllers of the HDDs 5 and 6 interpret the write instruction in the same way respectively to perform the same operation, so that the same performance with one drive is obtained. When a load (read) instruction is sent, on the other hand, only the HDD #0 5 operates normally to load the read data onto the MMU 2 and the read data is loaded again at this time. Thus, the same HDDs are put in parallel operation for writing and switched and operated for reading to double files with the same performance. Consequently, the safety of data is guaranteed and the performance is improved.
