Then, when far ultraviolet rays L having composite wavelengths of, e.g., 254 nm or near are radiated on the surface of the film 2 so that optical bridging reaction occurs on the surface, a high molecular layer 4 is formed on a reflection region. Then, after post-baking of the film 2, a photoresist film 5 is formed as the second layer. Hence, the first layered photoresist film is exactly prevented from being peeled due to an organic solvent existing in the second layered photoresist film.

Title: Detection switch
Inventor: OI KUNIO
IPC: H03K17/22
Filed: 1985-04-19
Abstract: PURPOSE:To prevent malfunction at the time of power-on operation and to realize one-chip formation in IC-implementation by providing a counter which outputs an operation signal for activating an output circuit when a clock pulse reaches a specific value and stopping inputting the clock pulse to the counter when the counter outputs the operation signal. CONSTITUTION:When the reset output terminal Q of a flip-flop circuit 14d falls to a low level, a AND circuit 13 inhibits the clock pulse P1c from passing, thereby stopping inputting the clock pulse P1c to the counter 14. The counter 14, therefore, stops counting and outputs an operation signal S14 continuously. Consequently, the output circuit is inactivated until a constant time Ta+Tb is elapsed from the power-on operation. Therefore, even if a light receiving circuit 7 outputs a detection signal S7 by mistake in a stable state right after the power-on operation, the output circuit 8 does not output an output signal S8, so the malfunction is prevented.

Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To provide a gas detector efficiently radiating the heat of a circuit part controlling a gas detection element and capable of being miniaturized. SOLUTION: The casing of a gas detector 1 has a cooling air passage 23 housing a circuit board 3 controlling a gas sensor 2 other than the detection air passage 22 housing the gas sensor 2. By this constitution,, the IC 3a for a power supply generating heat on the circuit board 3 and the radiation plate 3b of the circuit board 3 can be cooled by cooling air taken in from an open air introducing port 10. Therefore, the use of a radiation plate high in radiation efficiency is eliminated to make it possible to efficiently radiate the heat of the IC 3 for the power supply and the radiation plate 3b thereof. As a result, a radiation plate low in radiation efficiency, that is, a small radiation plate can be used and the size of the gas detector 1 is miniaturized.

IPC: G01C15/00
Filed: 1982-05-21
Abstract: PURPOSE:To make it possible to measure the distance and angle by one piece of a light wave distance and angle measuring device without changing its position regardless of the presence of an obstacle, by refracting the light emitted from the light wave distance and angle measuring device by a relay device, hitting the light to a target, and receiving the reflected light through the relay device. CONSTITUTION:A reflecting mirror 18 of a relay device 12 is arranged so as to form a right angle with a light wave axis. A light beam is emitted from a light wave distance and angle measuring device 11. Based on the light beam reflected by the reflecting mirror 18, a distance l1 between the light wave distance and angle measuring device and the reflecting mirror 18 is measured in advance. Then, the reflecting mirror 18 is slanted by a specified angle, and the reflected light from a reflecting prism 21, which is attached to a target 20 is detected through the reflecting mirror 18. Then, a length (l2+l1) from the light wave distance and angle measuring device 11 to the target 20 through the reflecting mirror 18 is measured. Thereafter the distance l2 between the reflecting mirror 18 and the target 20 is obtained. Since the reflecting mirror 18 for relay is used, the measurement can be performed by one distance and angle measuring device 11 without changing the position regardless of the presence of an obstacle.
