A stop lever is rotatable on a light shielding tunnel with an exposure aperture. When the stop lever is at a fast shutter speed position, a support pad is located below a lower metal plate of a synchronization switch of a flash circuit. The support pad holds the lower metal plate to limit rotation of a shutter blade, so that photography is carried out at a fast shutter speed. The synchronization switch is turned on after the exposure aperture is fully open. When the stop lever is at a slow shutter speed position, a support pad is away from the lower metal plate to obtain a slow shutter speed. It is possible to obtain a fast shutter speed by providing a light shielding tunnel with a fixed stopper to limit rotation of the shutter speed, and a slow shutter speed by providing a light shielding tunnel without a stopper.

A lens-fitted photo film unit includes a flash unit for applying flash light to a photographic object. An exposure amount changer, such as an aperture stop changing mechanism, changes over object light incident on photo film from the object between low and high exposure amounts. For the lens-fitted photo film unit, a photographic mode selection device includes a movable selector, such as a button, for selectively designating a daylight mode, a daylight flash mode and a night flash mode. The movable selector, when the daylight mode is designated, determines the low exposure amount and turns off the flash unit, and when the daylight flash mode is designated, determines the low exposure amount and turns on the flash unit, and when the night flash mode is designated, determines the high exposure amount and turns on the flash unit.

A first lens element and a second lens element for comprising a photographic lens, and a stop opening are arranged on an optical axis in this order. A stop plate has a stop-down opening. The stop plate is movable between a first position where the stop-down opening is inserted on an optical axis between the first and the second lens elements for making an f-number of the photographic lens f1, and a second position where the stop-down opening is retracted from the optical axis for making the f-number f2. The photographic lens is constructed to satisfy the following conditions: |log2(L/100)|

An opening and closing apparatus with a lock that is provided is capable of safely and promptly closing a sliding door, and also easily performing unlocking with a simple configuration. In an opening and closing apparatus with a lock for opening and closing sliding doors that are provided with elastic members at their door leading ends, output of an electric motor is transmitted to a rack-and-pinion mechanism or a lock mechanism. A control unit controls the electric motor such that a closing operation is performed, the closing operation operates the rack-and-pinion mechanism so as to move the sliding doors to a fully closed position and then displacing a link mechanism in a lock mechanism from an unlocking position to a locking position. Furthermore, the control unit controls the electric motor so as to reduce the output of the electric motor at a predetermined intermediate time point during the closing operation.

A thin film-forming apparatus, for ensuring uniform plane distribution of properties of a film formed on a substrate surface, has a gas-supply port 24a supplying a gas mixture from a gas-mixing chamber 24 to a shower head 25. The port is arranged at the peripheral portion on the bottom face of the gas-mixing chamber so that the gas mixture flows from the upper peripheral region of the head towards the center thereof. An exhaust port 32 discharging the exhaust gas generated in the film-forming chamber 3 is arranged at a position lower than the level of a stage 31 during film-formation directing the exhaust gas towards the side wall of the chamber 3 and discharging the exhaust gas through the exhaust port. The stage 31 is designed to move freely up and down to adjust the distance between the shower head 25 and substrate S.
摘要:
In order to provide a thin film manufacturing method and a thin film manufacturing apparatus, wherein a thin film with good reproducibility can be manufactured at low cost, and in a way wherein resources are saved, a dummy substrate (S2) is conveyed into a chamber (51), dummy processing gas is supplied to the dummy substrate (S2), a product substrate (S3) is conveyed into the chamber (51), and raw material gas different from the dummy processing gas, and containing therein metal material for manufacturing a thin film with the Metal Organic Chemical Vapor Deposition (MOCVD) method, is supplied to the product substrate (S3). Since the raw material gas is not used as dummy processing gas, the amount of metal material to be used can be inhibited, and a thin film with good reproducibility can be manufactured at low cost, and in a way wherein resources are saved.
