Title: Normal/reverse revolution torque limiter
Inventor: TAKADA SEIICHI
IPC: F16H35/10
Filed: 1990-07-30
Abstract: PURPOSE:To open a cover by a small torque, hold the cover at an arbitrary opening angle, and smoothly close the cover by winding a coil spring which is wound in the reverse direction to the normal revolution direction of a torque input member with the spread diameter in comparison with the diameter in a natural state. CONSTITUTION:When a cover 3 is opened, a gear 8 rotates in the normal direction, and since the direction is reverse to the winding direction of a coil spring 15, the force in the diameter spreading direction is applied by the frictional force of a spring sleeve 10, and the diameter increases, but the spring sleeve 10 is in natural state, and the width of a slit 11 does not vary, and also the outside diameter does not vary. Accordingly the frictional force between the coil spring 15 and the spring sleeve 10 reduces, and the cover 3 is opened by a small torque. When the cover 3 is closed, the coil spring 15 is twisted in the tightening direction, and the outside diameter is contracted, and also the width of the slit 11 of the spring sleeve 10 contracts. When the outside diameter of the coil spring 15 contracts, the approach to the diameter in natural state is generated, and the springy force reduces, but the spring sleeve 10 contracts, and the spring force in the diameter spreading direction increases, and a necessary frictional force is generated between the coil spring 15 and the spring sleeve 10.

Title: Image forming device
Inventor: NAKAMURA YASUSHI
IPC: G03G15/00
Filed: 1994-08-30
Abstract: PURPOSE: To provide an image forming device without necessitating a dedicated circuit for fusing a fuse and capable of surely fusing the fuse even when a commercial fuse is used. CONSTITUTION: In this device, a motor driving circuit 4 driving and controlling a motor 5 is utilized to fuse the fuse F2, and ordinarily, the fuse F2 is fused by outputting a PWM signal to the motor driving circuit 4 driving and controlling the motor 5, applying a specified current to a transistor Q4, and supplying the fusing current to the fuse F2. It takes much time until the fuse F2 is fused, at such a time, and the resistance value of the fuse F2 is increased while the fuse F2 is fused, and the fusing current supplied to the fuse F2 is decreased. By detecting a voltage value supplied to the input port 11 of a CPU 2, the CPU 2 varies the PWM signal outputted to a transistor Q3 and the higher current is applied to the transistor Q4 so as to increase the fusing current of the fuse F2. By controlling in such a way, the constant fusing current is always supplied to the fuse F2, and the fuse F2 is surely fused.

Title: Pressure sensor
Inventor: OKAMOTO EIJI
IPC: G01L1/00
Filed: 1997-07-15
Abstract: PROBLEM TO BE SOLVED: To improve the measuring accuracy by orienting the direction of zigzag-bending patterns of strain gauges which are formed in the pressure sensing part of a pressure response means and whose resistance values are changed due to deformation of the pressure sensing part. SOLUTION: The pressure detecting element is provided with a diaphragm as a pressure sensing part close to a pressure introduction hole. An insulation film is formed on the upper surface of the diaphragm and a gauge film is formed on the surface of the insulation film by pattern formation of etching process, thereby forming strain gauges G1 to G4. The gauges G1 to G4 are placed on a straight line L1 passing through the central part of the diaphragm, and the directions of zigzag-bending patterns thereof are oriented parallel to the straight line L1, and then every gauges G1 to G4 are connected as to form a bridge circuit. The resistance values of the strain gauges G1 to G4 are changed due to a pressure applied to the diaphragm, and as a result, a change in voltage is detected to measure pressure.  Thus, an influence of external force applied to the sensor at the time when a pressure sensor is fitted, can be suppressed.

Title: Inter-network cable testing method
Inventor: KUKIZAWA MANABU
IPC: H04M3/26
Filed: 1987-08-19
Abstract: PURPOSE:To improve accuracy without manual aid by setting folding paths in highway interfaces accommodated in the two sets of networks respectively, collating test data with reference data in a call processing part, and deciding whether an inter-network cable is normal or defective based on a collated result. CONSTITUTION:In a network 1-2, test data dt arrived from an inter-network cable 2-1 is accumulated through a channel p8, a folding path 71-5 and a speech path p9 to a received signal memory 15-2. A call processing part 4-1 extracts the test data dt from the received signal memory 15-2, and collates the data by the reference data dc, which have the same constitution with the test data dt previously held in the call processing part 4-1, and a collating part 41. When the test data dt are coincident with the reference data, the inter-network cable 2-1 is decided as normal. At the time of non-coincidence, the cable 2-1 is decided as abnormal, and the decided result is outputted to an output device. Consequently, it is needless to provide a device for the test, and there is no danger to generate an error by the manual aid.
