IPC: G03B9/70
Filed: 1988-09-29
Abstract: PURPOSE:To improve the operation accuracy by a simple constitution by stopping temporarily a motor by executing a reverse electric conduction to the motor before executing an electric conduction to a magnet, and executing an electronic flash light emission in a state that a shutter blade stops. CONSTITUTION:When a release button is operated in a state that an electronic flash photographing selection switch is closed, a release switch 29 becomes ON, and a control circuit 26 inputs an output of a distance measuring circuit 28 and determines a diaphragm value. Subsequently, a motor 1 is brought to forward rotation, and a shutter opening is opened. Next, when the number of pulses generated from a photointerrupter 13 in accordance with opening/ closing of a shutter blade coincides with the number of reference pulses corresponding to a diaphragm value, the circuit 26 reverses an electric conduction to the motor 1. In such a way, when a rotor of the motor 1 stops temporarily, a light emission of an electronic flash 25 is executed. Accordingly, the operation accuracy is improved by a simple constitution in which no cam is used.

Abstract: PURPOSE:To make it possible to form a highly accurate pattern without increasing high frequency power, by providing a sound wave generating mechanism for generating sound waves which are made to impact on the surface of a material to be etched with directivity so as to cross a plasma region. CONSTITUTION:High frequency power is applied on a lower electrode plate 13 from a high frequency power source 14. At the same time, a frequency of 800 kHz is applied to vibrators 18 from an oscillator 19 of a sound wave generating mechanism 17. Then, an upper electrode 12, which also serves the role of a vibrating plate, is resonated, and the similar frequency of 800 kHz is generated. The sound wave is made to impact on the surface of a wafer 20 on the lower electrode plate 13 with directivity so as to cross plasma 21. As a result, active, positive ions in the plasma 21 are generated between the electrodes 12 and 13 and accelerated by potential difference. The ions are further accelerated by the sound wave having the sharp directivity from the upper electrode plate (vibrating plate) 12. The ions become ion streams 22 having the high directivity. The ion streams are inputted in the surface of the wafer 20. Thus the surface part of the wafer 20, which is exposed from a resist pattern undergoes excellent ion etching.

Title: Aromatic and deodorizing product
Inventor: SAEGUSA KATSUMI
IPC: A61L9/12
Filed: 1987-09-30
Abstract: PURPOSE:To obtain aromatic odor stably for a long time by making volatilization rate constant by constructing so that a volatilization control plate set in contact with the upper surface of an aromatic and deodorizing product in a container descends naturally with a decrease in volume of the aromatic and deodorizing product due to its volatilization until the aromatic deodorant decreases to a prescribed level. CONSTITUTION:A volatilization control plate 3 is set in contact with the upper surface of an aromatic and deodorizing product 2 filled in a container, and it naturally descends in contact with the aromatic and deodorizing products with a decrease in volume of the product 2 due to its volatilization. In the case of the product 2 with high volatilization rate, the volatilization rate during early stage of use is suppressed by a volatilization port 4 of the volatilization plate 3. Volatilization are rapidly slows down when volume of the product 2 decreases to 1/5-4/5 of the original volume. At this period, descending of the volatilization suppressing plate is stopped by a protrusion 5 on the side wall of the container. Then, the upper surface of the liquid product is separated from the volatilization suppressing plate resulting in the widening of a volatilization area, whereby the volatilization rate becomes higher. Thus, volatilization rate is controlled at a constant value automatically.
