Title: Method for controlling laser gas pressure
Inventor: KARUBE NORIO
IPC: H01S3/036
Filed: 1987-06-30
Abstract: PURPOSE:To enhance the momentary output stability of an axial flow type CO2 laser and to improve cutting area accuracy in cutting work by controlling the operation point of a laser gas pressure so as to set it to a point of maximum laser output curve. CONSTITUTION:In a graph showing the relationship between a laser gas pressure and a laser output, an abscissa axis is a laser gas pressure P, and an ordinate axis is a laser output W. As shown, the laser output initially increases upon increase of the laser gas pressure P, and becomes maximum at a point B. Thereafter, it decreases as the laser gas pressure further increases. Accordingly, the laser output can be represented by W=-k(P-P0)<2>+W0, where the coordinates of the point B is (P0, W0). When the operation point of a point A is selected from this result, an output variation DELTAW1 is DELTAW1=-2k(P-P0) DELTAP. On the other hand, an output variation DELTAW2 when the operation point is at B, is DELTAW2=0. The laser output at this time is momentarily stable to improve its cutting area accuracy.

Title: Battery charging current control circuit
Inventor: KUDO MASAKAZU
IPC: H02J7/10
Filed: 1990-06-21
Abstract: PURPOSE:To make it possible to use a resistor and a battery for small capacity current limitation by performing analog battery charge current control thereby suppressing noise and preventing overcurrent flow through the current limiting resistor and battery. CONSTITUTION:When a charging current is fed from a power supply bus to a battery 1, a potential difference is produced across a resistor R1 and fed to the input terminal of a control section 2. When the potential difference is higher than a level preset in the control section 2, the control section 2 outputs a signal for controlling the base voltage of a transistor Q1 according to a predetermined rule so that the current flowing through the transistor Q1 will be lower than a predetermined level. Collector current of the transistor Q1, i.e. the charging current of the battery 1, is then controlled analogically to be lower than a predetermined level. According to the arrangement, a current higher than a predetermined level is prevented from being fed to the resistor R1 and the battery 1.

IPC: C03B18/10
Filed: 1987-07-02
Abstract: PURPOSE:To produce thin glass without cutting glass ribbon or to produce thick glass at high workability, by forming a level difference between the surface of the baths for the upper stream and the downstream by the impression of an electromagnetic force to molten metal, thus adjusting the thickness of glass ribbon to a target thickness between the first and second levels of the upper and the downstream baths. CONSTITUTION:The flow rate of molten glass 10 is adjusted by a refractory tool 11 and the molten glass flows down on the horizontal surface 13 of the molten metal in the first bath from an end of a lip 12. The flowed down molten glass has low viscosity and proceeds forward while spreading on the first bath surface 13 forming glass ribbon 16 having a thickness corresponding to the equilibrium condition. Magnetic field moving in the direction toward downstream is generated by a linear motor 19 provided below the bath 17, thus a thrust exerts in the downstream direction of the molten metal forming in the downstream side a horizontal second bath level 20 higher than the level of the first bath. The glass ribbon formed to a thickness corresponding to the equilibrium condition has a target thickness when it reaches the second bath level 20 after flowing down the inclined bath surface 22. Then, the molten glass is cooled, and desired float glass is produced.

Abstract: PURPOSE: To automatically close a safety valve by a method wherein a drop of internal pressure is detected when a safety valve has been placed in a sticking condition while it is in operation, to open the passage between actuators of the safety valve and a solenoid valve, supplying a fluid pressure.  
     CONSTITUTION: A safety valve 3 is equipped with a valve body 4 having a fluid- supplying opening, a valve stem 6, a compressing spring 7 for opening the valve, and an actuator 8. When the interval pressure of the equipment used 1 is increased to operate the safety valve 3, but when the valve stem 6 does not return to the place where it was, causing the safety valve 3 to be kept open and placed in a sticking condition, and when the internal pressure of the equipment used 1 has dropped up to the point below the set value, a compression switch 13 operates to change a solenoid valve 14 to the port for a passage 15, so that a fluid pressure such as compressed air is supplied to a fluid pressure cylinder 9. Thus the piston 10 and rod 11 of the actuator 8 are pushed forward, forcing the safety valve 3 to close.

Title: Sample holder device for sputtering
Inventor: MURAKAMI MOTOYOSHI
IPC: C23C14/34
Filed: 1991-07-04
Abstract: PURPOSE:To prevent the film forming surfaces on substrates from being contaminated by forming the holder of a sputtering device consisting of the substrate holder and a pallet which rotates and revolves the substrates at the circumferential difference between the diameter of the holes provided on the pallet and the outside diameter of the holder to a rotation system of a specific structure. CONSTITUTION:The contact surfaces of the substrate holder 2 fixed with the substrates 1 for sputtering and the pallet 3 holding the holder 2 are coated with 'Teflon (R)' 4 having a low coefft. of friction. Targets 5 are disposed on the front surfaces of the substrates 1 and the films of the target materials are formed on the substrates 1 in a gaseous Ar atmosphere. Since the contact surfaces of the substrate holder 2 are coated with the 'Teflon (R)' 4 which is a material having the low coefft. of friction, the friction on the rotating surfaces of the pallet 3 and the substrate holder 2 is small at the time when both rotate and revolve and, therefore, the peeling of the films of the target materials sticking between the pallet 3 and the substrate holder 2 at the time of sputtering and the staining of the recording surfaces on the substrate surfaces by sticking of these films onto the substrates 1 are obviated. The disks having high quality are thus stably produced.
