Title: Hot-water boiler
Inventor: INOUE TADASHI
IPC: F24H1/40
Filed: 1982-12-20
Abstract: PURPOSE:To maintain a shell wall of a combustion chamber at a relatively high temperature, prevent dusts, tar or the like from being adhered to the shell wall and enhance heat-exchanging efficiency, by a method wherein a gap is provided between an outer shell body provided with a hot water supplying pipe and an inner shell body provided with a water-supplying pipe, and a flow-controlling cylinder is provided at the gap. CONSTITUTION:An inner shell body 3 is concentrically provided in a flue 2 provided in the interior of an outer shell body 1, and the flow-controlling cylinder 5 is provided at the gap formed between the shell bodies 1, 3. Combustion air is supplied into a combustion chamber 15 through the flame holes 18 of an inner cylinder 19, while a fuel is pressure-sprayed into the chamber 15 through a nozzle 16, is mixed with combustion air, and is burned at an upper part of the chamber 15. The resultant high-temperature combustion gas flow upward through the flue 2, passes through an upper gap 8 while being restricted by the flow-controlling cylinder 5, flows downward through an inner gap 7, flows into an outer gap 6 through a communicating hole 9 provided at the lower part of the cylinder 5, and is discharged to the exterior of the heater through an exhaust cylinder 11. Accordingly, the combustion gas is subjected to heat exchange three times at the inside wall of the inner shell body 3, at the outside wall of the iner shell body 3 and at the inside wall of the outer shell body 1, whereby the shell wall faced to the combustion chamber 15 is maintained at a relatively high temperature.

Title: Fluid compressor
Inventor: MATSUKAWA KAZUHIKO
IPC: F04C29/02
Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To stably suck oil by an oiling pump by forming a projection part on a part faced to the oil reservoir part of a housing member so as to position its tip end lower than an oil surface of an oil sump part, and enclose the circumference of a driving shaft part. SOLUTION: A rib 26 is radially arranged on a side faced to a bottom part oil reservoir 14 of a lower housing 7 so as to enclose a crank shaft 10, and a tip end of the rib 26 is positioned lower than an oil surface. Flow circulating a circumference of the crankshaft 10 tends to be generated in lubricating oil of the oil reservoir 14 by following after a rotating crankshaft 10, but flow of the lubricating oil is obstructed by the rib 26 formed so as to enclose the crankshaft 10. With this, in the vicinity of the crankshaft 10, such turbulence of an oil surface that the oil surface falls down extremely is suppressed, and the oil surface is stabilized. And it can be suppressed that the oil surface of the oil reservoir 14 is disturbed by coolant gas supplied into the casing 2 by an intake pipe 18.

IPC: F16H19/00
Filed: 1999-08-06
Abstract: PROBLEM TO BE SOLVED: To provide a disk carrier mechanism capable of lowering a mechanism height, and shortening the length of a depth. SOLUTION: This disk carrier mechanism 90 is provided with a flexible rack 73, a pinion 72 for driving this rack 73, and a guiding groove 75 for guiding the movement of the rack 73.

The jigs b-1 and b-2 can be fitted in the receiving teeth 9-1 and pressing-in teeth 9-2 to press the stacked fiber in the closest packing state. Consequently, transmission loss caused by the mutual engagement of respective single multifilament optical fibers is eliminated.

Filed: 1985-10-11
Abstract: PURPOSE:To provide the titled device, by providing a screw feeder for recovering a nonfused magnetic particulate developer into a recovering casing, and a vibrator for applying an elastic wave vibration to a recording medium, the vibrator being disposed on the back side of the recording medium oppositely to a slit of a slitted annular electromagnet. CONSTITUTION:To remove a nonfused developer 2b adhered to the face side of an ordinary paper 1, a required exciting current is supplied from a DC power source 9 to a coil of a slitted annular electromagnet 6 in synchronism with the feeding of the paper 1 in the direction of an arrow A by rotating feeding rollers 3, 4, 5, thereby magnetizing a magnetic annular body 8, and a screw 13 of a screw feeder 11 is rotated so as to recover the developer 2b. By this, both tip parts of the magnetic annular body 8 on the opposite sides of a slit (t) of the electromagnet 6 are made to be magnetic poles N, S. Therefore, a developer 2a fused to the paper 1 being fed in the direction of the arrow A and the nonfused developer 2b are sequentially attracted magnetically between the magnetic poles N, S. Further, elastic wave vibrations of a vibrator 14 ensure easy separation of the nonfused developer 2b from the face side 1a of the paper 1, so that the nonfused developer 2b is magnetically attracted to the magnetic poles N, S with favorable efficiency.

Title: Character position detector
Inventor: TERAI HIROYUKI
IPC: G06K9/34
Filed: 1993-09-10
Abstract: PURPOSE:To stably segment a character even when uneven density exists in a character image in the case of detecting the position of a character for character recognition. CONSTITUTION:A characte image (a) fetched by an inspection image inputting circuit 1 is stored in a density image memory 2. The sum (projection data) of a density image in the direction rectangular to the arrangement direction of a character expressed by the density character image (b) is found out by a character direction projecting circuit 3. On the other hand, a reference pattern preparing circuit 5 prepares a reference pattern (e) based on the width and interval of the character. Positional relation is found out based on correlation function (f) between the pattern (e) and projection data (c) to determine the position of the character. Even when the density of the character image (a) is uneven and a part of the character is incomplete, a position most coincident with the image (a) is obtained from the whole mutual relation.

Title: Synchronous motor controller
Inventor: ASO TAKESHI
IPC: H02P21/24
Filed: 1995-08-10
Abstract: PROBLEM TO BE SOLVED: To obtain a controller which can continue vector control even if a permanent magnet is deviated. SOLUTION: An inverter 2 converts a DC into an AC power and supplies the AC power to a synchronous motor 3. A rotating angle θsen of a rotor of the synchronous motor 3 is detected by an angle sensor 4, a drive current is detected by current sensors 5, 6 and a drive voltage is detected by voltage sensors 12, 13 and these data are outputted to a control 200. In the controller, the vector control is performed on the basis of a torque command value T* and a rotating speed ω of the rotor and thereby the drive current is controlled to follow a control command. In this case, a magnetic pole position estimation arithmetic device 15 estimates the magnetic pole position θcal on the basis of AC current and voltage, while an angle correction device 14 calculates the estimated position θcal of magnetic pole.  Thereafter, an error is obtained by subtracting θcal from θsen and it is corrected to θsen after intensity adjustment depending on the rotating speed. Thereby, the magnetic pole can be detected accurately and it is no longer required to set the estimated period of the magnetic pole position equal to the control period of current and the calculated load can be alleviated.
