Title: Rotation detecting device
Inventor: TANAMACHI KAZUHIRO
IPC: B23Q17/22
Filed: 1982-07-08
Abstract: PURPOSE:To detect with high accuracy the rotation of a rotating body, by providing the first detecting part and the second detecting part for detecting a variation of the first and the second square wave signals from a rotary encoder, respectively, and obtaining a pulse signal from a detecting signal of each detecting part. CONSTITUTION:The first and the second square wave signals (a), (b) from a rotary encoder are inputted to terminals 21, 22. When only the first square wave signal (a) becomes a high level at time t1, both output signals from both output ends of a latching circuit 23 are in a low level, therefore, a signal (e) of a high level is outputted from an output end of the first EXOR 24 and is supplied to a pulse width control part 29 through an OR gate 26. The EXORs 24, 25 and the OR 26 constitute the first detecting part 27. At time t1, a control pulse of prescribed pulse width is outputted to a clock input end of the latching circuit 23 from the control part 29. At time t1, a signal at a low level is inputted to an input end of the third EXOR 28 for constituting the second detecting part, therefore, a detecting signal (h) at a low level is outputted from its output end, also is inverted by an inverting circuit 30, and logic ''1'' and ''0'' are outputted from the gates 31, 32, respectively.

Title: Press die with coil cutter
Inventor: BEPPU KIMINORI
IPC: B23D15/08
Filed: 1986-05-26
Abstract: PURPOSE:To enable the use of a press die both for cutting a long coil and for normal press work by so supporting an upper cutting edge in an upper die as to be movable vertically and providing a lift position changeover means and another means for pushing the upper cutting edge upward. CONSTITUTION:In a normal press work, a maximum lift position restricting plate 18 is fixed at a position for giving the larger liftable distance of an upper cutting edge 13 for an upper die 11. In this state, when the upper die 11 is lowered, the upper cutting edge 13 and a lower cutting edge 14 do not interfere with each other and do not out a coil 'C'. Then, when the coil 'C' is cut, said plate 18 is so positioned and fixed as to shorten the maximum liftable distance of a holder 15 for the upper die 11. In this case, the lower cutting edge 13 comes down compressing a urethane spring 40, due to the lowering of the upper die ll, and intersects the lower cutting edge 14, thereby cutting the coil 'C'. According to the aforesaid constitution, no operation power is required and a burden on a worker can be reduced.

Title: Control method of injection pressure of motor-driven injection molding machine
Inventor: KAMIGUCHI MASAO
IPC: B29C45/50
Filed: 1987-05-20
Abstract: PURPOSE:To prevent a mold from damaging by preventing surplus injection pressure from generating, by a method wherein when a detected injection pressure has become a preset mold protection pressure or higher by detecting injection pressure at the time of an injection process, the process is not shifted to a dwell process, but shifted to a measuring process. CONSTITUTION:When a fact where an injection pressure has become a preset mold protection pressure or higher due to some reason or other is detected by a pressure detector 2 through an A/D converter 24 during an injection process, a CPU 12 for PMC starts a timer by controlling output torque of a servomotor 3 to a torque limit value corresponding to low pressure of safety pressure preset on a common RAM 18. When the time of the timer is up, treatment of a dwell process is not performed and then shifted to treatment of a measuring process. In other words, when there is a fear where the injection pressure exceeds the mold protection pressure due to some reason or other and the mold may be damaged at the time of injection, damage of the mold is prevented by turning output torque into safety pressure by controlling the output torque to low torque immediately.

Title: Vibro-isolating support device
Inventor: TOKUDA NAOAKI
IPC: F16F13/00
Filed: 1987-05-20
Abstract: PURPOSE:To make a large vibration in the horizontal direction absorbable by installing an air spring and a laminated rubber vibration isolator, extending each cylinder body of both inner and outer cylinders to the lower part from a diaphragm lower end, and attaching a sliding member to a clearance in this extended part in the circumferential direction. CONSTITUTION:When a large roll acts on a vibro-isolating support device, an outer cylinder 3, receiving horizontal force, comes into contact with an inner cylinder 5 via the sliding member 20 attached to the clearance in the circumferential direction without contacting with the inner cylinder 5 directly. Consequently, vertical relative motion of these inner and outer cylinders 5 and 3 is almost in no case checked and, what is more, a diaphragm 4 forming an air spring 1 receives no damage so that, even if such a case, function of the vibro-isolating support device is maintainable. That is, vertical movements are absorbed by the air spring 1, while horizontal movements by a laminated rubber vibration isolator 2, respectively, thus a vibro-isolating function can be brought into full play.

Title: Method for monitoring measured value
Inventor: MAEJIMA ATSUSHI
IPC: G01D7/00
Filed: 1983-07-04
Abstract: PURPOSE:To make it possible to monitor the measured values by the same unified processing system, by converting and processing the data, which requires the monitoring of the abnormal state of the display data of the measured values. CONSTITUTION:A remote monitoring control device 1 collects state display data SV and measured-value display data TM for control from various pieces of equipment and devices in various places and inputs the data into a computer 2. The computer 2 stores the data SV and TM into storing areas 3 and 4, respectively. The data in the storing area 3 is inputted to a monitoring processing part 5, where the state is monitored. Measured-value display data TM1, which requires the abnormality monitoring process of the data TM, is inputted to a data converting part 6, where the data TM1 is converted into a pseudo-state display data SVD. The data SVD is stored in a storing area 7. The data SVD has the same type as the SV and becomes the normal/abnormal state data of the measured value. The SVD is inputted as a monitor input SVP into the processing part 5 together with the data SV. Thus the monitoring process of the data TM is performed. Therefore, the same program is used for the monitoring process for both data of the data SV and the data TM requiring the abnormality monitoring process in the processing part 5, and the data is processed simultaneously.

Title: Light source for infrared ray and its manufacture
Inventor: MURAKAMI YOSHIHIKO
IPC: G01J3/10
Filed: 1994-06-02
Abstract: PURPOSE:To improve S/N ratio of an infrared spectrophotometer by using a sintered body of a silicon carbide which is dense and can be processed by discharging, forming a fine resistance circuit intensively, thereby obtaining an infrared light source having a concentrated plane light-emitting part. CONSTITUTION:A sintered body of silicon carbide which is dense and has a sintering density of 2.8g/cm<3> or more and a high, emissivity, is used. The sintered body shows superior resistances to oxidation and corrosion with a high mechanical strength at a high temperatures. Therefore, the sintered body is stable in efficiency as an infrared light source 11. Since a specific resistance of the sintered body at room temperatures is not larger than 1OMEGA$.cm, the sintered body can be processed finely by discharging. For instance, a disc-shaped sintered body of silicon carbide having diameter of 100mm and thickness of 5mm is cut out by a wire discharge process, and a part made thin (having a width of 0.4mm) is superposed on a light-emitting part on the tip end to allow every wire to receive radiation heat. The plane infrared light source 11 having the fine resistance circuit formed densely as above is obtained. The light source 11 has a high luminance and a high emissivity and is concentrated without an irregularity in the light-emitting part, so that S/N ratio of an infrared spectrophotometer is improved.
