Abstract: PURPOSE:To improve load dispersing properties of an equalizer, and thereby relaxing accuracy in working by letting the equalizer be supported by a lever by means of a pin so as to be freely rocked in such a way that the rocking center of the equalizer is positioned at the midway between two each of the valve rods of a fluid pressure control valves. CONSTITUTION:When the load of an automobile is transmitted to an equalizer 1 via a lever 6, the equalizer 1 is evenly strucked in contact with two rods 16, the load is divided into two so as to be applied to two valves 19 constituting a fluid pressure control valve 15. In this device, the equalizer 1 is supported by the lower 6 via a pin 7 so as to be freely rocked. And the pin 7 is arranged at the position where the rocking center of the equalizer 1 corresponds to the midway between two each of the rods 16. By this constitution, the load of the automobile can be evenly dispersed to two each of the valve 19 via the equalizer 1 regardless of the accuracy in working of the equalizer 1, thereby preventing disorders such as the pull of braking and so on.

Filed: 1998-01-14
Abstract: PROBLEM TO BE SOLVED: To extremely reduce the damage due to oscillatory friction, and to sufficiently perform the function like a pulley by forming an inward flange on which a belt is put on and side, in the belt penetrating holes, and by providing the outer circumferences of the connecting parts between the flanges and the one piece body with roundness. SOLUTION: A body 1 is provided with holes 3 for passing through a bolt, and each hole 3 is not simply punched, but is cut and bent; and a flange 4 on which the belt is put on and moved is formed at the cut and bent part. By adjusting the height of the hole 3 and the thickness of one-piece, the end of the cut and bent part is butted on the belt. The outside 5 of the bent part is formed into natural roundness of thickness due to bending working, and the sliding belt is smoothly slid in both the front and rear directions by the roundness. When the thickness is thin and the roundness is not sufficiently large, the bending angle is made to be an obtuse angle, or the roundness is made larger than that in the natural bending. Then, the sliding of the belt is smoothed, and the one-piece sufficiently perform the function like a pulley.

Title: Pulverized coal combustion device
Inventor: MUTO HIDETAKA
IPC: F23C99/00
Filed: 1999-02-16
Abstract: PROBLEM TO BE SOLVED: To reduce heat load in the vicinity of a side wall of a combustion furnace and increase the excess air ratio of a burner provided on a wall surface of the furnace, which is suitable for preventing formation of a reducing atmosphere. SOLUTION: Among coal feeding pipes 5 which connect a mill 4 and a burner 7, the radius of a coal feeding pipe 5a extending to a burner 7a which is arranged in the vicinity of a side wall 8b adjoining a furnace wall 8a of a furnace 8, where the burner 7 is located, is made smaller than that of a coal feeding pipe 5b which extends to a burner 7b at the central portion of the wall 8a. Accordingly, the amount of fuel supplied to the burner 7a is reduced compared with that supplied to the burner 7b at the central portion of the wall 8a where the burner 7 is located. Thus the excess air ratio of the burner 7a positioned adjacent to the side wall 8b is increased, the amount of air in the vicinity of the side wall 8b is increased, slagging caused by the reduction of heat load is suppressed and incomplete combustion of the fuel is suppressed to suppress production of CO.  Further, the amount of sulfide produced by combustion of the fuel is suppressed by suppressing generation of uncombusted fuel and permitting reducing atmosphere in the flames to decrease, thereby preventing the wall surface of the furnace from being corroded.

Abstract: PURPOSE: To obtain a large vibration sound in a small-size, light-weight and thin buzzer by fitting  an AC electromagnet and a permanent magnet to opposite faces of two elastic viration plates  which have the circumference part fixed and are provided oppositely.   
     CONSTITUTION: Elastic vibration plates 9 and 10 are curved and shaped into a round dish form,  and rim parts 11 and 12 are superposed to each other so that respective concave parts 13 and 14  may be opposite. Then, the circumference of them is fixed to each other in one body by covering  part 12 with part 12 by the method of caulking, etc. Cylindrical magnetic core 16 is fitted to the  center of inside face 10a of vibration plate 10 by adhesive, etc., and coil 17 is wound around  magnetic core 16. Then, when coil 17 is excited, N and S poles are formed at both edges of  magnetic core 16 in the axis direction. Cylindrical permanent magnet 18 is inserted into inside  hole 16a of magnetic core 16 so that this magnet 18 can reciprocate freely, and the other edge is  fitted to inside face 9a of vibration plate 9 by adhesive, etc., so that N and S poles may be fixed  at both edges in axis direction.

Title: Delay circuit
Inventor: SEKI TERUO
IPC: H03K5/13
Filed: 1988-02-22
Abstract: PURPOSE:To stably generate the delay of fixed period signal transmission by not concerning with pull-down and pull-up actions in the early stage continuity of two switch devices with a capacity load and concerning after a fixed period when the continuity early stage passed. CONSTITUTION:Just after an input signal is changed into an 'L', a P channel FET42 is continued, a current I1 flows, a current I2 flows through resistance Rs, and as a result, since the source.drain current of a P channel FET43 does not flow, a current Lu to a C1 does not flow. Consequently, the level of an output side is an 'L' in the period while it rises at the charging electric potential fixed value of a capacity CB, and the delay action of an inter-input/output- signal is executed for that time. On the other hand, just after the input signal is changed into an 'H', an N channel FET47 is continued, a current I4 flows, a current Is flows through the resistance Rs, and as a result, since the source.drain current does not flow, the current from the capacity load C1 does not flow. Consequently, the output side level maintains the 'H' in the period while the charging electric potential is the fixed value, and the delay action of the between input/output signals is executed.
