Title: Scanning type exposure system and measuring method of visual field stop position
Inventor: GOTO EIJI
IPC: H01L21/027
Filed: 1998-02-04
Abstract: PROBLEM TO BE SOLVED: To prevent an irregular exposure from occurring in a scanning type exposure system by a method wherein a means which measures the position of a visual field stop is provided, and projection optical systems which project an image of a mask pattern joining exposure regions together for exposure are corrected on positional deviation of a visual field stop. SOLUTION: The shape of a slit 20a provided to a slit plate 20 is scanned keeping the visual field stops 45 of projection optical systems stationary to measure the position of the visual field stops 45. That is, the edge position of the opening 45a of a visual field stop 45 is obtained resting on the position of a slit 20a obtained by a laser interferometer 57, a position where a photodetector sensor 50 varies in output and an ideal edge position of a visual field stop are compared with each other, whereby the deviation of the edge position of the opening 45a of the visual field stop 45 is detected, and the visual field stop 45 is corrected on a positional deviation by a visual field stop drive mechanism 56. By this setup, irregular exposure can be prevented from occurring.

Title: Mold for injection molding
Inventor: UBUKAWA HIROHISA
IPC: B29L31/30
Filed: 1990-01-31
Abstract: PURPOSE:To enable appearance-defect to be surely removed, while on the rear of a molded object, concavity is not molded by a method in which a back-cut member is arranged at a projected position in the starting of injection, and it is moved to a retracted position immediately before the finish of injection. CONSTITUTION:The end of the main body by a molding is set between a top force 3 and a bottom force 4, and molten material is injected into a cavity 5 from a gate 6. A back-cut member 15 is raised to a projected position by the spring force of a compression spring 14, and the upper end of a back-cut piece 17 is arranged oppositely to the gate 6. Consequently, injected molten material collides with the back-cut piece 17 and makes a circuit upward and sideward, and then the cavity is filled therewith. Accordingly, there is no possibility that the appearance-defect such as flow mark or flash is generated on the surface of its distal part 2. Immediately before the finish of injection, when the filling pressure in the cavity with molten material exceeds the spring force of a compression spring 14, the back-cut member 5 is lowered to a retracted position, while it compresses the compression spring 14, and the upper end-surface of the back-cut piece 17 is arranged at the position which coincides with the molding face of the bottom force 4. Accordingly, the rear of the distal part 2 is molded smoothly with the upper end-surface of the back-cut piece 17.

Title: Compensating system for interference wave
Inventor: INOUE TAKEO
IPC: H01Q3/26
Filed: 1979-03-02
Abstract: PURPOSE:To secure elimination of the interference wave by giving the adjustment to both the phase and the amplitude of the auxiliary antenna so as to obtain the minimum correlation between the output of tha auxiliary antenna and the composite output of the auxiliary and main antennas. CONSTITUTION:The control is given to the amplitude and the phase of the interference wave which is the output of auxiliary antenna F2 via amplifier G, phase shafter I and attenuator (amplifier) J each. And then the interference wave is compounded with the output of main antenna F1 through compounder unit H. Shifter I is then actuated to give the comparison through correlating unit K to the correlation between the output of unit H and that of antenna F2, and then the adjustment is given to secure the minimum correlation. At the same time, attenuator (amplifier) J is actuated to give adjustment in the same way to the amplitude so as to secure the minimum correlation. In such way, shifter I and attenuator J are actuated to supply the signal featuring the same amplitude as and opposite phase to the interference wave component contained in the output of the main antenna from the auxiliary antenna. Thus the interference wave can be negated.

Title: Logical circuit provided with output protective circuit
Inventor: KANDA MASAAKI
IPC: H03K19/088
Filed: 1978-03-02
Abstract: PURPOSE:To normally maintain the action of a TTL circuit, by preventing the thermal failure of output transistors by interruption driving the output transistors under conduction surface conditions by means of a protective circuit only when the collector potential becomes not less than a fixed level. CONSTITUTION:A protective circuit is shaped by transistors (Tr) 14, 15, dioses 18, 19 and resistances 16, 17. When an output Tr7 is under a conduction condition, the collector potential of a current driving Tr6 is low, base current does not flow through the Tr 14 and the Tr 14 is under an interruption condition. When not less than a fixed level abnormal voltage is applied to an output electrode 3 under this condition, current flows through a base of the Tr 15 through the resistance 17 and the diode 19 and the Tr 15 is brought to the conduction condition. The base current of the output Tr7 flows through the Tr 15, and the output Tr7 is brought to the interruption condition. The action of a logical circuit is not prevented because the Tr 14 is conducted when the output Tr7 is under the interruption condition and the interruption condition of the Tr 15 is maintained. Thus, the thermal failure of the output Tr7 can be prevented, and the action of the TTL system logical circuit can normally be kept.

Title: Method and device for controlling clutch-operating pressure
Inventor: NAKAMURA HIDEKI
IPC: F16D48/02
Filed: 1979-03-02
Abstract: PURPOSE: To improve a controlling property in a halfly engaged clutch state, by keeping clutch-operating pressure at a constant high level at an initial stage, engaging a clutch, then sharply reducing the pressure to halfly engage the clutch, then slowly reducing the pressure and thereafter aliminating the pressure in the operating range of a brake.  
     CONSTITUTION: When an operating pedal 11 is released, the rod valve 23 of a clutch-operating pressure controller 4 is at the left end and a pressure regulating valve 22 is also at the left end. As a result, working oil from a hydraulic pump 3 is all conducted from an inlet port 32 to an outlet port 34 through an annular recess 31 and selectively supplied to clutches 6, 7 through a changeover valve 5. When the pedal 11 is depressed to thrust the valve 23 to a position to connect a port 42 and another annular recess 39 to each other, the valve 22 is appropriately moved rightward through the medium of a spring 25 and the cross-sectional area of the inlet port 32 is reduced. As a result, oil pressure at the outlet port 34, namely, clutch oil pressure is sharply reduced. When the valve 23 is thrusted further, the other valve 22 is moved rightward further. As a result, the clutch oil pressure is eliminated.
