Title: Pulse laser device
Inventor: KANEHARA YOSHIHIDE
IPC: H01S3/03
Filed: 1982-10-19
Abstract: PURPOSE:To obtain the pulse laser output, whose peak value and pulse frequency are high, by imparting sound wave vibration to a laser medium gas in a three axes crossing type pulse laser device, thereby shortening the delay in rise up of the output of laser light. CONSTITUTION:A pulse instruction device 13 outputs a signal, which generates pulse discharge 5. The voltage of the signal is amplified to the voltage required for the pulse discharge 5 by a power source 4. The pulse discharge is generated between two electrodes 3A and 3B. The output signal from the pulse instruction device 13 is amplified by an amplifier 15 through a phase device 14 and drives a sound wave vibration generator 12. An ordinary speaker and the like are used as the sound wave vibration generator 12. The sound wave vibration generated by the sound wave vibration generator 12 imparts the vibration to a laser medium gas 2 in the part of the pulse discharge 5. At this time, the phase of the sound wave vibration generated by the sound wave vibration generator 12 is made to match the phase of the pulse discharge 5 generated between both electrode 3A and 3B. Thus the delay in rise up of the output of laser oscillation is made sufficiently small, and the peak value of the pulse laser output is made high.

The roller 53 of each arm member 5 runs onto the plate cam 61 of the slide shaft 6, an arm member 6 is moved outwards with respect to the axis and the inside surface of the solidified layer of molten metal is pressed with the pressurizing roller 3. When the pressurizing device 4 is advanced at low speed while the metal frame is revolved as it is, the inside surface of the solidified layer of molten metal is uniformly pressurized. Pressurizing force is taken as 10 - 20kg/mm<2>.

Title: Diaphragm device
Inventor: HATAMOTO MITSUOKI
IPC: F16J3/02
Filed: 1996-07-12
Abstract: PROBLEM TO BE SOLVED: To reduce displacement resistance in diaphragm and make it high displacement and low stiffness by receiving a load with a disk with large area, providing a membrane functioning as a diaphragm with narrow width between the disk and a cylinder and guiding the displacement of the membrane with a regulating member. SOLUTION: A diaphragm is constituted of a disk 10 receiving fluid pressure at the lower surface and a load with the upper surface, a membrane 11, a cylinder 12 and a regulating member 13. As the disk 10 displaces in the axis direction to the position the fluid pressure and the load balance. The membrane 11 is extended in the cylinder 12 side and shrunk in the disk 10 side. By specially receiving the load with the disk 10 with large area, load on the membrane 11 around the disk 10 is avoided. The regulating member 13 guides the displacement of the membrane 11 to a limit and ensures stable operation. For the membrane 11 functioning as a diaphragm, a film with a narrow width, thin and low load resistivity can be used and thus, the displacement resistance of the diaphragm can be made small, high displacement and low stiffness.

Title: Automatic setting system of transmission and reception line equalizer
Inventor: MIWA YUUICHI
IPC: H04B3/04
Filed: 1983-09-30
Abstract: PURPOSE:To set automatically an equalizing stage of a line equalizer by storing the amount of equalization to an attenuation in advance in response to a distance of a transmission line. CONSTITUTION:When a transmission level is set to -2dB or -6dB to a transmission line of a certain range, a tap selection signal based on the level selection is fed to a microprocessor 16. The processor 16 discriminates which equalizing step in the qualizer is to be selected by using data of a proper equalizing amount corresponding to the attenuation stored in an ROM or the like. If it is discriminated that a 4dB equalizing stage is to be selected to a 2dB level, the processor 16 turns on a switching element S1 to allow the system to select the 4dB selecting stage. Similarly, an 8dB equalizing stage is selected to a 6dB level. The proper equalization for the line is set automatically in this way.

The leaked magnetic flux G is detected by the detecting element D on the top surface, and the  leaked magnetic flux G' is detected by the detecting element D' on the back surface. The relationship between the leaked magnetic fluxes G and G' and the de- tected signals X and Y after the amplification in amplifiers H and H' in the detecting elements D and D' is such that the signals X and Y linearly extend in a symmetic pattern, with the leaked magnetic flux (a) as the ordinate and the thickness of the thin steel plate (b) as the abscissa. The magnitude of the defect can be judged by the signal of X+Y. By normalizing with the value of X+Y, the position can be judged by using the signal of X-Y as a depth signal.
