Title: Production of photomask and semiconductor device
Inventor: OGOSHI TAKESHI
IPC: G03F1/62
Filed: 1990-07-24
Abstract: PURPOSE:To facilitate the attachment and detachment of a pellicle frame without using an adhesive by simultaneously pressing the pellicle frame for adhering and fixing at a specified distance provided from the pellicle and a photomask and fixing the frame and the photomask by using attachable and detachable jigs without providing an adhesive layer therebetween. CONSTITUTION:The pellicle frame 12 for adhering and fixing the pellicle apart the specified distance provided therefrom and the photomask 13 are simultaneously pressed and are fixed by using the attachable and detachable jigs without providing the adhesive layer between the frame and the photomask. For example, the jigs for simultaneously holding and fixing this pellicle frame 12 and the photomask 13 is constructed to press the pellicle and the photomask by utilizing the elastic force of the jigs themselves. Since the adhesive is not used for fixing the photomask and the pellicle frame in such a manner, the adhesive does not remain on the photomask at the time of removing the pellicle frame and, therefore, if a substitutive pellicle frame is previously prepd. the immediate use of the photomask is enabled by instantaneously exchanging the pellicle frame. The mass productivity thereof is greatly improved in this way.

Filed: 1986-08-20
Abstract: PURPOSE:To prevent oil from oozing by pressing a brake plate which is a pressure member against a paper web only when the paper web is taken up around a take-up roll. CONSTITUTION:A driving motor 30 is driven forward to rotate a shaft 31 and a gear 32 as shown by an arrow (a) and a timer Tm1 is started. Consequently, the brake plate 20 rotates as shown by an arrow (b) and is pressed against the paper web P wound around a web roller 11. When the timer Tm1 enters a time-up state, the timer Tm1 stops rotating forward and then rotates reversely as shown by an arrow a' and a timer Tm2 is then rotates reversely as shown by an arrow a' and a timer Tm2 is set, so that the rotation of the motor is carried on until then timer Tm2 enters a time-up state. Consequently, the brake plate 20 leaves the paper web P of the web roller 11 to be released from the press-contacting state. Consequently, the oil Oi with which the paper web P is impregnated never oozes.

IPC: H03K17/78
Filed: 1989-07-27
Abstract: PURPOSE:To adjust trade-off between response speed and a detection distance at an optimum point by providing a means controlling a current flowing to a projecting element in response to the period of an adjustment means. CONSTITUTION:An oscillator 1 is provided with a variable resistor 1a, and the period (frequency) is made variable by a variable resistor 1a. A monostable multivibrator circuit 2 outputs a projecting pulse signal (b) present synchronously with the leading or trailing edge of a clock signal (a) being the output of an oscillator 1, and an F/V converter 3 converts the frequency of the clock signal (a) into a voltage. A gate circuit 4 leads out an output of the F/V converter 3 when the signal (b) is at a high level, that is, for a projecting pulse width only and a maximum value of a projecting current IF flowing to a projecting element 6 depends on the output of the F/V converter 3. Thus, trade-off between response speed and a detection distance is adjusted at an optimum point, and a photoelectric switch requiring a long detection range is obtained for application permitted slow response speed.

Title: Infrared ray tracking device
Inventor: IIDA TORU
IPC: G01S3/786
Filed: 1992-06-30
Abstract: PURPOSE:To distinguish a target from a decoy by providing a circuit for detecting that the direction of move of the decoy is different from that of the target when the decoy is dropped during tracking of the target. CONSTITUTION:When a target is captured, a switch 12 gives the output of a detection circuit 4 to a servo amplifier 5 for tracking. The angular velocity of a gimbal is detected by a detector 7 and the change rate is detected by a differentiation circuit 8. The attitude angle of a gyro optical system 2 is detected by a goose neck angle detector 13 and the value is stored in a storage part 14. When the target drops a decoy, the dropping rate of the decoy is large and the dropping direction is opposite to the traveling direction of the target, thus enabling the output of the detector 7 to have a large change range in negative direction. Then, the output of the differentiation circuit 8 is compared with a threshold by a comparison circuit 9 and the level of the output of an AND circuit 11 becomes high immediately after dropping the decoy. The switch 12 is controlled to select the output of the storage part 14 when the output of the AND circuit 11 is at a high level as the input of the servo amplifier 5.
