IPC: B65G47/24
Filed: 1998-07-27
Abstract: PROBLEM TO BE SOLVED: To provide an aligning method and device for an irregular shape work piece, which can efficiently align the works by making use of roughly U-shaped workpiece. SOLUTION: A work 2 to be fed through a carrying conveyor 4 from a press device 1, is held by the holder 14 of a work stopper. A first work 2 at the specified position F is held by the holder 14, and also is held by the grip 16 of a carrying device while being left as in a regular attitude so as to be rested over the carry-in end of an aligning conveyor 8. After a second work 2 is held by the holder 14, the cylinder 15 of a work stopper 13 is drawn back so as to be positioned at a shift position B, is then held at this position by the grip 16 of the carrying device, and is turned over so as to be brought into an inverse attitude by means of a rotary actuator 22 thereafter.  When the second work 2 is rested over the aligning conveyor 8, the aligning conveyor 8 is advanced by one pitch, and the following third work is rested over the aligning conveyor 8 in the regular attitude similarly with the first work 2.

Title: Stepping motor
Inventor: HANATSUMI HIROSHI
IPC: H02K37/14
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To obtain a stepping motor in which a dispersion in the strength of a magnetic circuit is eliminated and in which the magnetic interference between stators is prevented effectively by a method wherein a hole which reduces the cross section of the connection part on the side of a second stator is formed in a magnetic-substance frame in a position which faces the mutual interval of internal yokes. SOLUTION: At a magnetic-substance frame 1, holes 4 which reduce the cross section of the connection part of a first stator 35a to a second stator 35b are formed near the central part in the axial-line direction, i.e., in positions facing the mutual interval between an internal yoke 34a on the side of the stator 35a and an internal yoke 34b on the side of the stator 35b when a stepping motor is assembled. Thereby, the magnetic insulation degree between both stators 35a, 35b can be increased, and the magnetic interference between both stators 35a, 35b can be suppressed. Consequently, it is possible to prevent a rotation irregularity from being caused by a magnetic interference when an exciting pattern is changed.

Title: Counter test method
Inventor: TSUNEOKA TAKASHI
IPC: H03K21/40
Filed: 1989-08-17
Abstract: PURPOSE:To allow the method with the less member of patters for test and not to decrease a maximum operating frequency at the time of testing by controlling a clock, a reset signal and a carry-in signal for each counter for an object to be tested so as to conduct the test. CONSTITUTION:Outputs of a 12-bit counter exist in 4096 ways by permutation of 12 bits, but test is conducted for 4-bit output each of the counter through the division of the counter constitution, then test patters required only 16X3=48 ways. The operating limit frequency fmax of the period counter is expressed in equation I, where Tpd is a propagation delay time of the counter, Tsu is a set up time and Tskew is a skew of the clock. The skew Tskew is suppressed small because of the limited effect only in the wiring coverage length in a gate array, thereby improving the operating limit frequency fmax.

Abstract: PURPOSE:To make the circuit board cheap by providing a storing means consisting of a Bloch line as an information carrier and a driving means to read out the information, providing a means to connect both and enabling a storing means tobe attachable and detachable from the driving means. CONSTITUTION:The storage means mounts a Bloch line memory element 2 composing a storing part on a card form of the circuit board 1 and provides a point of contact 4 at the edge part of the board 1 and the point of contact 4 is made to be attachable and detechable from a connector 10 in a memory device body 5. Withthis connection, an electgric signal and a control signal being necessary to the element operatioln or an electric current are conducted to the board 1 from the body 5 becoming a driving means. A drive system 6 (a coil, a magnetic circuit and a permanent magnet) of the body 5 is made to a position relation to clamp the element 2 and the magnetic field generating at the drive system 6 is efficiently impressed on the element 2. Hence since a drive system is not included in the board 1, the thickness of the board 1 can be as thin as the element 2 and since the board 1 does not have the drive system 6, the board 1 can be produced at a cheap price.

Title: Form board for ballast concrete casting for installation of track
Inventor: SUZUKI TOYOHITO
IPC: E01B37/00
Filed: 1997-08-06
Abstract: PROBLEM TO BE SOLVED: To improve the function of forms, by connecting an inside form board to which the upper and lower form boards are bendably connected, to the inside end face of track cases embedded by half into a ballast concrete form. SOLUTION: In the inside form board for a ballast concrete form, the upper form board 20A and the lower form board 20B are bendably connected to each other through a hinge 20C and a recess in which a sleeper 1 is fitted is provided at the upper edge of the form board 20A. When ballast concrete 8A is placed in a traveling section of a curved way, the form board 20A is bent by the hinge 20C in accordance with the inclined angle of cant to closely stick to the opening of the inside end face of the track cases 3A and close the opening. And hence, since any gap is not brought between the form board 20A and the inside end face opening of the track case 3A, placed concrete is prevented from flowing into the track case 3A and hence, concrete is prevented from sticking to an elastic material 2 supporting both ends of the sleeper 1.  In this way, the forms can be installed and assembled without spoiling the vibration- absorbing function of the elastic material.

IPC: B60H1/12
Filed: 1982-12-02
Abstract: PURPOSE:To prevent increase of ventilation resistance and improve the faculty of a blower by forming a recessed part for arranging a revolution control resistor, on the inside surface of a blower case so as to be contiguous to an air inlet port for cooling fan motor, in a blower unit for car. CONSTITUTION:A recessed part 12 is formed on the inner wall surface 11a of a blower case 11, and a resistor 6 is arranged in the recessed part 12, and the cooling air intake port 13 for a fan motor 5 is arranged in close to the resistor 6. Since the resistor 6 is not projected into an air passage 7 in the above-described constitution, the air supplied by a Sirocco fan 4 passes without being obstructed by resistance, and the cooling air for the fan motor 5 certainly flows into the intake port 13 from the recessed part 12. Therefore, the resistor 6 can be cooled sufficiently. With such a constitution, the increase of passing resistance due to the resistor is prevented, and the resistor can be cooled sufficiently even in a low wind speed, and the faculty of the blower unit can be improved.

Title: Starter device for electric motor
Inventor: KATO KIYOHARU
IPC: H02P1/26
Filed: 1988-08-29
Abstract: PURPOSE:To enable a restart to be performed of an electric motor avoided in its period giving an influence of voltage drop by detecting a value of residual voltage and its phase in the electric motor when it is in the instantaneous restart. CONSTITUTION:Power voltage 101 and residual voltage 102 of a large induction motor 1 are in a reverse phase further with the residual voltage 102 of the large induction motor 1 relatively in a large value; here a range 103, giving an influence in the time of reclosing a power source, is detected by a residual voltage protecting device 10 and break block signal 11 is output so as to disable a closing breaker 2 from closing. In the other period with a less influence of the residual voltage, because no breaker block signal 11 is output, the closing breaker 2 is closed in the power source, enabling a restart to be attained of the large induction motor with a less influence of the residual voltage. Thus by detecting a value of residual voltage and its phase in the motor in the time of its instantaneous restart, the electric motor performs its restart by avoiding a period giving an influence of voltage drop.
