Title: Laser irradiating device
Inventor: ISHIKAWA KEN
IPC: C21D1/09
Filed: 1980-02-06
Abstract: PURPOSE:To vary the energy distribution of laser beam, by using a composite lens made of plural condenser lens pieces having the optical axis part eliminated. CONSTITUTION:The laser beam L is irradiated to the composite lens 6 made of two condenser lens pieces 8a and 9a obtained by eliminating the optical axis part from the ordinary convex lenses 8 and 9 each. The beam L passed through the lens 6 is divided into two semicircular luminous fluxes S1 and S2 to be converged toward the focuses on the optical axes P1 and P2 of the lenses 8 and 9 each. In this case, the position is replaced between the fluxes S1 and S2. Thus, for instance, a high energy distribution is obtained at the periphery of the area along the line II-II in the diagram with rather a low and uniform energy distribution obtained at the center line, respectively.

Title: Split runner of hydraulic machine
Inventor: NIIKURA HIROYUKI
IPC: F03B3/12
Filed: 1979-02-09
Abstract: PURPOSE: To reduce the spring constant of a flange and prevent united flanges from splitting into two by forming spot facings in the contact faces of the fastening flanges through which a bolt is applied tightly.  
     CONSTITUTION: Shallow spot facings 6 are formed in the contact faces of flanges 5, 5 of a split runner which is tightened with a nut 4 with a bolt 3. The flange 5 reduces in spring constant by a load due to formation of the spot facing 6 in it so that a straight line (c) rises less which represents deflection of the flange 5 clamped by applied load rises less. Deflection δ 5  of the flange applied with an early tightening force P 0  is growing. While the bolt under external force F2 is subjected to deflection δ 6  the flange 5 is kept under compression stress and therefore prevented from splitting.

Title: Magnetic recording/reproducing device
Inventor: FUJIMOTO YOSHIHIRO
IPC: G11B5/024
Filed: 1989-01-23
Abstract: PURPOSE:To prevent the double writing actions by shifting a magnetic head to both the position of a reference track to be recorded on a magnetic disk and the position of the magnetic head where the maximum output level is secured for a head amplifier which is recorded in a memory circuit and performing an erasing operation. CONSTITUTION:The position of a magnetic head 3 where the maximum output level of a head amplifier 8 is secured is outputted from a comparator 11 and stored in a memory circuit 12. The head 3 is shifted to the position stored in the circuit 12, and the head 3 is connected to an erasing circuit 9 via a changeover switch 6. Thus an erasing operation is carried out at the position of the head 3 where the maximum output level of the amplifier 8 is secured. Then a control drive circuit 7 moves the head 3 to the reference track position of a magnetic track and carries out an erasing operation there. Thus the head 3 performs the earing operations at the reference track position and the actually recorded position of the magnetic track where the output level of the amplifier 8 is maximum. As a result, the recorded video signals are completely erased and therefore the video signals are never written double.

Abstract: PURPOSE:To improve the operability and the reliability, by providing a switching circuit, which makes a load current continuous, between a generator, which is used as  a damping machine of the expansion turbine, and a load to control the turbine in accordance with the difference between the real speed and a set speed of the turbine. CONSTITUTION:An AC output generated from a synchronous generator 2 by an expansion turbine 1 is rectified in a part 7 and is absorbed through a transistor (TR) 10 by  a load 3. The frequency of the output of the synchronous generator 2 is converted to  a voltage signal by an F/V converter 19, and a speed set by a speed setting equipment  5 is converted to a voltage signal also, and the difference between both voltages is amplified in a part 18 as the difference between the real speed and the set speed. When  the actual rotational frequency of the expansion turbine 1 is larger than the set value,  the difference between the output voltage of the F/V converter 19 and the voltage of  the setting equipment becomes positive and is amplified in a part 18 to turn on a TR  24, and the turn- on time of a TR 23 and the TR 10 of the switching circuit is longer,  and the time of the load state of the synchronous generator 2 is longer; and when the  actual rotational frequency of the expansion turbine 1 is smaller than the set value,  the time of this load state is shorter. Thus, the rotational frequency is controlled.
