Title: Cutting length controller
Inventor: MASUMORI MASATOSHI
IPC: B23D36/00
Filed: 1991-08-20
Abstract: PURPOSE:To provide a cutting length controller capable of using a cobble shear to cut crops at the front and rear ends of a bar steel and setting the cutting length to a desired length. CONSTITUTION:A material detecting means 5 detects the ends of the bar steel respectively on the inlet and outlet sides of an upstream rolling stand 2. A rotary detecting means 6 detects the rotations of the upstream rolling stand 2 and the cobble shear 3 respectively. A cutting length setting means 7 sets the cutting length of the end part of the bar steel 1. A change-over timing calculating part 8 tracks the end of the bar steel 1 in accordance with the outputs of the material detecting means 5 and the rotation detecting means 6, the time at which the cutting point decided by the cutting length of the cutting length setting means 7 reaches the cobble shear 3 is estimated and a change-over command to a selector 4 is outputted earlier by a prescribed time of motion delay than the estimated time. A lead ratio correcting value calculating part 9 preestimates the cutter position of the cobble shear 3 in accordance with the outputs of the material detecting means 5 and the rotation detecting means 6 and the lead ratio correcting signal of the cobble shear 3 is outputted so that the cutter is positioned at the bottom dead point when the cutting point of the bar steel 1 reaches the cobble shear 3.

Title: Heat pump type air-conditioner
Inventor: FUNAKOSHI SAHO
IPC: F24F11/02
Filed: 1997-08-01
Abstract: PROBLEM TO BE SOLVED: To improve heating capacity when defrosting is effected on an outdoor heat-exchanger through rationalization of the opening of a pressure reducing device and provide comfortable heating environment. SOLUTION: During heating operation, a refrigerant flows in the direction of a solid arrow mark by a four way valve 2. A control device 9 detects the number of revolutions of a compressor 1 by a sensor 10, calculates a target value Tdm of the discharge refrigerant temperature of the compressor 1 according to the number of revolutions thereof, and controls the opening of a pressure reducing device 4 such that a discharge refrigerant temperature Td of the compressor 1 detected by a sensor 6 coincides with the target value Tdm . When defrosting occurs to a heat exchanger 5, the pressure reducing device 4 is further throttled so that the discharge refrigerant temperature Td of the compressor 1 due to lowering of an evaporative temperature is compensated for lowering thereof.  But, when an outside air temperature is lower than a set decision temperature, after the lapse of a given time, correction is effected such that the target value Tdm is reduced. The opening of the pressure reducing device 4 is controlled such that the discharge refrigerant temperature Td of the compressor 1 coincides with the corrected target value Tdm .

Filed: 1996-08-07
Abstract: PROBLEM TO BE SOLVED: To provide a motor having a magnetoresistive sensor which can detect the rotational speed or the like accurately without requiring a highly accurate positioning. SOLUTION: In a motor, a field region where the flux density of a plane perpendicularly intersecting the main flux from a magnetized part for generating signal, i.e., an FG magnetized part, exceeds the rated sensitivity of a reluctance sensor is formed by the magnetized part for generating signal. In addition, the magnetoresistive sensor is disposed in the field region such that the magnetosensitive face thereof will be in parallel with the plane and the output of the magnetoresistive sensor is saturated.  According to the arrangement, dependency of the output characteristics B of the reluctance sensor on the fluctuation of gap between the FG magnetized part and the reluctance sensor is lowered significantly as compared with the output characteristics A of a conventional sensor and the allowance (b) of positioning error of the magnetoresistive sensor can be widened as compared with a conventional allowance (a). Consequently, conventional highly accurate positioning work of the magnetoresistive sensor and a jig therefor can be eliminated.

Abstract: PURPOSE:To realize the device which is small in size and lightweight and has good assembly performance by forming a magnetic circuit of permanent magnetic around a lens frame guide shaft, and supplying a current to a drive coil arranged crossing its magnetic flux and driving a lens frame. CONSTITUTION:When a zoom command is supplied to a drive circuit 76, a coil 83 is fed with electricity in a direction based upon the command.

Those signals Zt and Ht are inputted to a microcomputer 72 to calculate the position of a lens group 34 for holding an image plane at a constant position and a focus signal Mt. Further, the position signal Ft of a lens group 34 is inputted to the microcomputer 72 from a focus encoder 69. The microcomputer 72 controls a circuit 73 until the signal Ft matches the signal Mt to drive the lens group 34 to the specific position.

Abstract: PURPOSE:To control an increase in the temp. of a target material and to uniformize the temp. distribution by providing plural protrusions at specified intervals on the surface of a baking plate to which the target is bonded. CONSTITUTION:The back of the target material 11 is bonded to the backing plate 12 by solder.
