Title: Pulse motor driving system
Inventor: YOSHIMURA GENICHI
IPC: H02P8/32
Filed: 1981-11-28
Abstract: PURPOSE:To prevent the occurrence of unnecessary vibration at stopping, by detecting rotor speed at the time of stopping on an objective position by a detector, and giving speed decrease torque to a rotor just before reaching an objective position via a waveform controller. CONSTITUTION:A start signal SP and a motor PM position detector PDC signal are put into an OR circuit. A motor PM is controlled via a gate G, a divider DIV, and a driver DRV. Output of the OR circuit is counted by the counter CON and compared with an objective position setting signal OPS. The gate G is controlled. Both comparing signal and signal of the detector VDC detecting rotor speed (dtheta/dt) are put into a waveform generator SCC, thereby the driver DRV is controlled. Therefore, speed decrease torque can be given to a rotor just before reaching an objective position corresponding to its intrinsic attenuation coefficient. This enables stopping with prevention from unnecessary vibration.

Title: Method for controlling page turning operation of passbook printer
Inventor: GOTO TAKEHIKO
IPC: B41J13/26
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To speed up page turning operation by a method wherein a passbook is conveyed and a top printing page of one side of the passbook being sprung on a friction roller, which a pressure roller comes into contact with and separates from, is reversed so as to place it on a top printing page of the opposite side. SOLUTION: A passbook 1 conveyed by a conveying roller 3, when its head part passes the position of a rolling friction roller 7 and arrives at the position of a sensor 17, is conveyed for a predetermined distance, and stopped. Then, a pressure roller 8 is raised so as to pinch the passbook 1 with the rolling friction roller 7. By a low speed rotation of the rolling friction roller 7 in the clockwise direction, a right side top printing page of the passbook 1 is curved. Thereafter, when the rolling friction roller 7 is rotated at a high speed, the turned top printing page is sprung. When this operation is detected by a sensor 16, the rolling friction roller 7 is rotated in the counterclockwise direction and the page turning operation is completed.

Title: Waterproof type cable cramp structure
Inventor: KAMIMURA HIROKI
IPC: F16L5/02
Filed: 1999-07-06
Abstract: PROBLEM TO BE SOLVED: To improve waterproof effect for a waterproof container, and to improve workability of the container by forming a packing groove on a surface where a waterproof cramp main body and a cap are brought into contact with each other, and on a surface perpendicular to a cable, and mounting a packing made of an elastic material in the packing groove. SOLUTION: When a cap 6 is mounted on a waterproof cramp main body 2, the waterproof cramp main body 2 and the cap 6 are brought into contact with each other at surfaces 2f, 6b perpendicular to a cable 81. A packing groove 16 is formed on a surface 2f of the waterproof cramp main body 2 side, and a packing 15 made of an elastic material is mounted in the groove 16. As a result, the waterproof cramp main body 2 and the cap 6 are surely and tightly fitted to each other through the packing 15. Even if a liquid material invades through a clearance between a screw part 2a of the waterproof cramp main body 2 and a screw part 6a of the cap 6, the liquid material is prevented from invading from a position where the packing 15 is disposed into a downstream side. It is thus possible to prevent the liquid material from invading into an inside 20a of the waterproof container 20.

Title: Holder of needle rolling bearing
Inventor: IRINO TAKAO
IPC: F16C33/51
Filed: 1990-07-19
Abstract: PURPOSE:To make the number of supported rolls even number plus 1 to enable the increase of a load capacity, and reduce displacement of a division part to be caused by the centrifugal force, and prevent abnormal abrasion by dividing a holder into a large and a small tow pieces unevenly. CONSTITUTION:A holder 1, which is divided into a large and a small two pieces unevenly in the circumferential direction, is installed to the peripheral surface of a small diameter part 7 of a supporting shaft 6. Multiple rolls 2 are arranged in the holder 1, and if the holder 1 is divided evenly, the number of the rolls 2 is defined to an even number. But, since the holder 1 is divided unevenly, the number which is obtained by adding 1 to the described number is possible, and a load capacity at the time of design can be increased by that quantity. This holder 1 is rotated in response to the rotation of the supporting shaft 6, and the centrifugal force works at this stage, but since the divided surfaces 5, 5 are out of a diameter line, the holder 1 is never deformed into an ellipse. Consequently, abnormal abrasion is prevented-from being caused by mutual collision of the divided surfaces 5, 5.

Filed: 1984-09-17
Abstract: PURPOSE:To start a programmable controller accurately with use of many timers of short time bases by counting the time base reaching frequencies to produce the elapsed time information data and integrating this time information with the present time value data of the timer to always renew this time value data. CONSTITUTION:The cycle of the fixed cycle signal produced from a fixed cycle signal generator 22 is coincident with the time base of a timer. The contents of a register provided in a CPU21 are saved a sequence program processing mode corresponding to the signal input and stored temporarily to another memory. The count value of the input frequencies of the fixed cycle signals is added by 1, and 1 is added to the storage contents of a count memory 24. The storage contents of the memory 24 thus renewed are used as the elapsed time information in a single scan. The storage contents of a register within a CPU1 are reset to a state set before discontinuation of processing to complete a series of processes. For the post-processing of the elapsed time information, the interruption is inhibited for the input of the fixed cycle signal. Then the elapsed time information data in a single cycle signal. Then the elapsed time information data in a single scan is transferred to an elapsed time information memory 25, and said inhibition of interruption is released for the next measurement of the elapsed time.

Abstract: PURPOSE:To obtain a stable transmission characteristic over a wide band by transmitting a signal while distributing the signal of a coaxial cable for a frequency area to plural balanced paired cables. CONSTITUTION:Coaxial cables 1-1 and 1-1' are inserted while facing to transmitters 4-1 and 4-1' using those cables, and the signal from the coaxial cable 1-1 of the transmitter 4-1 on one side is distributed to the N balanced paired cables (5-1)-(5-N) and transmitted by the balanced paired cables for each divided band while dividing the frequency band by first-order inductances L1-Ln of transformers 2-1 and 2-N and capacitors 3-1 and 3-N connected in parallel to a first-order coil. Further, by setting the capacity of the capacitors 3-1 and 3-N, the capacitors 3-1 and 3-N stabilize the transmission characteristic even in the vicinity of the cross frequency of frequency band division. Thus, transmission is available over the wide range exceeding the band limit.

Abstract: PURPOSE:To reduce a time constant and to operate an apparatus at high speeds by constituting a sense circuit of a grounded-emitter transistor and means for feeding back output data from a collector of the transistor to a common data line. CONSTITUTION:When data of a memory cell MC1 is to be read out, a bit line selecting signal Y1 is turned to an H level to turn ON a transistor(Tr) QY1. A voltage difference is generated between right and left bit lines BR1 and BL1 of the cell MC1 corresponding to the data stored in the memory cell MC1, which is added to bases of TrQ1 and TrQ2. In consequence, either of the Q1 and Q2 is turned ON corresponding to the data of the MC1 and a large current is supplied to either one of the common data lines CDL and CDR. Accordingly, the circuit is not dependent on collector load resistors RLL, RLR of grounded- emitter transistors TrQEL, TrQER. A time constant of a collector node is sufficiently reduced by making the RLL, RLR small.
