Title: Laser oscillator
Inventor: OMATSU HIDEFUMI
IPC: H01S3/131
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To attain accurate irradiation reproducibility of an output beam by adding a voltage signal and a develop signal, i.e., an output signal from a current value retaining means having reverse polarity, through an adder and inputting the output signal from the adder to a power supply section for feedback control. SOLUTION: When an output beam 2 is irradiated from a laser resonator 1, an AC signal is generated by driving a switching power supply section 6 with the output signal from an irradiation command section 7. The AC signal is boosted at a boost transformer section 5 and passed through a rectifying/ smoothing section 4 to produce a DC signal which is passed through a current detector 3 in order to supply a DC current. An output voltage signal value from the current detector 3 is inputted to an adder 12 and a current value retaining means 11. The adder 12 adds the output current value of the current detector 3 and a signal obtained by inverting the polarity of an output current VH from the current value retaining means 11 to produce an output signal which is then inputted to the switching power supply section 6 for feedback control.

Title: Part detecting device
Inventor: AOYAMA YOSHITAKA
IPC: B23K11/30
Filed: 1993-05-05
Abstract: PURPOSE:To change whether a part exists or not into a signal, and to prevent the drop out of the part by providing a detecting means in order to detect the existence of the part inside the electrode receiving hole of the projection welding. CONSTITUTION:When a part 5 is inserted inside a receiving hole 11, 10, the existence of the part 5 is detected with a sensor 12, the signal showing the existence is transmitted to a controller, and the advance of an electrode 1 is acted. Because if the signal of the existence of the part 5 is not transmitted, the signal of the advance of the electrode 1 is not transmitted, so the electrode 1 is not advanced as the part is dropped out. Further, because the attractive magnetic force is applied on a shaft part 6 of the part 5, so the shaft part 6 is closely stuck on one side of a guide hole 10, in such a way, the part 5 is held. Therefore, the trouble to the following process can be avoided before. Further, because a holding means in order to prevent the drop down of the part 5 is provided, even if the electrode 1 is in any direction, the drop down of the part is not generated.

Title: Instruction for rotary/straight advance unit
Inventor: KUWABARA MASAYUKI
IPC: G05B19/42
Filed: 1988-06-06
Abstract: PURPOSE:To permit the instruction in the revolution direction in the standstill state in the straight advance direction by carrying out the instruction only in the revolution direction by correcting the turning angle of a ball screw nut in correspondence with the turning angle of a ball spline nut. CONSTITUTION:When a tool 7 is revolved under setting a motor 12 for rotary shaft in nonexcited state, a ball screw spline shaft 18 and a ball spline nut 6 revolve at the same time. The turning angle shift quantity of the ball spline nut 6 at this time is detected by an encoder 17 for rotary shaft, and a motor 8 for straight advance shaft is turned so that the ball screw nut 3 is revolved by the equal quantity to the detected angular shift quantity. Therefore, even if the ball screw spline shaft 18 is revolved by the revolution of the tool 7, the ball spline shaft 18 is in the standstill state in the axial direction and carries out only revolution. Therefore, the instruction for only in the revolution direction can be executed, independently of the instruction in the straight advance direction.

Title: Image forming device
Inventor: OZEKI YUKIHIRO
IPC: G05D23/19
Filed: 1988-06-09
Abstract: PURPOSE:To prolong the life of a fixing and heating part by storing a first fixing temperature, a second fixing temperature which is higher than the first one and a preheating temperature which is lower than the first one, and controlling the heating part on the condition corresponding to the timing when power supply is turned on and when image formation is instructed. CONSTITUTION:If the timing when power supply is turned on is synchronous with the timing when a print signal is inputted, a fixing heater 8 is continuously driven through a fixing heater drive circuit 11. When a thermister 6 detects that peripheral temperature of the fixing roller 7 exceeds the first fixing temperature and that the roller reaches the second fixing temperature at which an image can be fixed immediately after driving has started, a CPU 1 drives a main motor 10 through a motor drive circuit 12. The peripheral temperature of the fixing roller 7 is maintained at the second fixing temperature until a counter 14 counts in X-hours. When the counter 14 is up, the CPU 1 stops the fixing heater 8 until the peripheral temperature of the fixing roller 7 drops to the first fixing temperature. In this way, the life of the fixing and heating part is prolonged even if a rated voltage varies greatly by controlling the fixing heater 7 on the condition corresponding to the timing when driving power supply is turned on and the timing when the print signal is inputted.

Filed: 1978-11-17
Abstract: PURPOSE: To prolong the life of a semiconductor device by selecting the thermal expansion coefficient of an insulator for fixing a terminal plate and forming a terminal retainer lower than that of lead wires.  
     CONSTITUTION: A semiconductor 2 and a lead wire 3 are connected through brazing filler 4 to a copper or iron heat dissipating electrode plate 1, and the lead wire 3 is connected at its end to a terminal plate 7 secured by insulating resin 6 with brazing filler 9. The brazing filler between the semiconductor pellet 2 and the lead wire 3 and the brazing filler 4 between the pellet 2 and the electrode plate 1 are affected by shearing strain and tension or compression load in response to the difference of the thermal expansion coefficients among the materials to thereby finally cause them to be broken due to fatigue in their heat cycle. Glass fiber-contained insulating resin is used for the terminal retainer 6 to thereby adjust the mixture ratio of glass or fiber to the resin so as to adjust the thermal expansion coefficient thereof to meet the material of the lead wire 3. When the material is so selected that the thermal expansion of the heat dissipating electrode plate and the terminal retainer may always be lower than that of the lead wire and compression force is always applied to the pellet, the life of the semiconductor device is extended approximately twice as much.
