Abstract: PURPOSE:To reduce a decrease in contrast by providing stops in an optical path where main reflected light passes and in an optical path where incident light passes, and then preventing reflected light from reaching a screen. CONSTITUTION:In a projection lens 6, a 1st stop 8 which selects emitting ray of light 13 from a reflection type dispersion liquid crystal panel 5 and a stop 9 on a mirror 2 or a stop 9' at a part of the lens barrel of the projection lens 6 as a 2nd stop which cuts off a part of incident light 10 on the dispersion liquid crystal panel 5 are provided. The 1st stop 8 cuts off and removes the majority of scattered reflected light 15 when the dispersion liquid crystal panel is OFF, and characteristics such as a ratio of the luminance to contrast of a reproduced image projected on the screen 7 can be varied according to whether or not the aperture area of the stop is large or small. The 2nd stop 9 improves action for reducing reflected light generated on the lens surface of the 1st group lens 3 of the projection lens and spreading characteristic of light made incident on the reflection type dispersion liquid crystal panel to improve the contrast characteristics.

Title: Logic circuit
Inventor: KUDO TSUNEAKI
IPC: H03K19/003
Filed: 1991-02-13
Abstract: PURPOSE:To eliminate a spike signal from a logic signal and to prevent malfunction by delaying an input signal for a prescribed time and allowing a logic gate to decide an output signal level according to the delay time. CONSTITUTION:A delay circuit 1 receiving an input signal A outputs a signal B with a delay of time alpha. The time alpha is set depending on number of inverting gates connected in cascade. An OR gate 2 outputs OR output C of the signals A, B. The signals A, B at an L level simultaneously are not given to the OR gate. Thus, an output signal C is always at an H level even when a spike signal is caused in the input signal, resulting that the spike pulse signal is easily eliminated from the input signal and malfunction of the circuit using the output signal C is prevented. The pulse width of the spike signal desired to be eliminated is optionally set by the adjustment of the delay time alpha. A pulse signal with a longer width than the time alpha is outputted.

Abstract: PURPOSE:To improve the light resistance and prevent the deterioration of data retrieving efficiency of an optical information recording medium by adding a specific billirium compound to a recording layer composed mainly of a polymethine coloring matter. CONSTITUTION:A recording layer composed mainly of a polymethine coloring matter is provided on a substrate, and a protective layer is provided, if necessary, to form an optical information recording medium. In this medium, a billirium compound having a maximum polymethine color absorption of -50nm or +150nm is added to the recording layer. The billirium compound is highly effective for improvement of the light resistance and for prevention from the deterioration of data retrieving efficiency of the optical information recording medium, if added to the recording layer. Further, its effect can be increased by adding the compound to not only the recording layer but also to another layer e.g. a primary layer or the protective layer or both layers. The weight ratio of polymethine coloring matter and billirium compound in the recording layer is 30:70 or 99:1. The effect decreases significantly, if the billirium compound has a maximum polymethine coloring matter absorption of less than 50nm and more than 200nm.

Abstract: PURPOSE:To inhibit gear movement during an original scan and prevent malfunction by allowing a speed change gear to move only when two control claws of a driving clutch and the clutch of the speed change gear are both separated. CONSTITUTION:A control claw 58 is arranged for a spring clutch 36 for power transmission, a control pawl 59 is arranged for the spring clutch 41 for the speed change gear, and a spring 87 is energized in a disengaging direction all the time.

Title: Laser beam machining method
Inventor: SUGAWARA MASAYUKI
IPC: B23K26/082
Filed: 1996-02-07
Abstract: PROBLEM TO BE SOLVED: To re-start laser beam machining without causing any defective machining by retracting the program locus by the prescribed distance from a point at which cutting is stopped, piercing a work at the retracted point, and starting the cutting again in the cutting direction from the piercing point. SOLUTION: When the machining continuation is commanded after a temporary stopping of the machining, the program locus is retracted by the prescribed distance L1 in S200. The machining condition for piercing is selected in S201. Piercing is performed by re-starting the machining gas ejection, the laser beam irradiation, etc., in S202. When piercing is completed, the machining condition for cutting is selected in S203, and then, cutting is again continued along the program locus in S204. Because piercing is performed in S202, and then, machining is re-started, machining can be continued without causing any defective machining even when the retracted position is a non-cut position.
