Title: Film unit with lens
Inventor: KAMEYAMA NOBUYUKI
IPC: G03B7/085
Filed: 1994-10-17
Abstract: PURPOSE: To miniaturize a film unit with a lens by using a capacitor having absolute minimum capacitance, as a main capacitor. CONSTITUTION: As a photographic film 23 loaded in the film unit with the lens, an ISO 800 high-sensitivity film is used. When the throw of strobe light is made constant, the absolute minimum capacitance of the main capacitor 55 of a stroboscope unit 15 is made smaller as the sensitivity of the film 23 is higher. Therefore, the film unit with the lens which incorporates the ISO 800 film 23 can use the capacitor having a size smaller than that in a conventional film unit with the lens in which an ISO 400 film is loaded, as the main capacitor 55. It is miniaturized so that the stroboscope unit 15 can be miniaturized and the film unit with the lens incorporating the unit 15 can be miniaturized as well.

Abstract: PURPOSE:To form a highly accurate tapered pattern of silicon in a simplified process by a method wherein a process to etch a silicon layer anisotropically and a process to oxidize an exposed face of the silicon layer is repeated alternately in an identical container. CONSTITUTION:During a first etching operation 141, a polycrystalline silicon layer 3 is etched by a depth S1; then, by a first O2 plasma treatment 151, an SiO2 film 191, for sidewall protection use, of a width w1 is formed on an upper face 3A and sidewall faces 3B of an etched part.

Abstract: PURPOSE:To exactly measure the surface condition of a sample by operating a fine adjustment mechanism for focusing in such a manner that the respective signals obtd. in a focusing detection circuit are made equal thereby controlling the sample surface to the focusing state. CONSTITUTION:Projection objects 21, 22, 23, 24 are disposed in the different positions near an optical axis LL' and are projected respectively onto a projection object (sample) 4, by which the image thereof is picked up.

The pattern of a period P is used for O21, O22 and the pattern of a large period P' is used for O23, O24 and therefore, O23, O24 have the pattern flaring at the tail as compared to O21, O22. A differential signal is obtd. by using the focusing detection circuit 71' having the differential focusing circuit forming the signals O22-O21, O24-O23 from said focusing signal. The control is effected from the distance apart from the focusing state by using the sum signal (O22-O21)+(O24-O23) of the differential signal, by which the measurement with high accuracy is made possible.

Title: Automatic paper feeder of printer
Inventor: ITOU NORITSUGU
IPC: B65H3/06
Filed: 1985-11-08
Abstract: PURPOSE:To surely feed paper sheets one by one, by arranging a motion converting mechanism composed of a pinion and a rack member and a clutch adapted to release the urging pressure of a pressing member. CONSTITUTION:A motion converting mechanism 48 is composed of a feed roller 23 adapted to be rotated by a paper feed motor, a pinion 45 operationally coupled to the above-mentioned motor and rack member 47 meshed with the latter. Further,a pressing member 29 is supported by the rack member 47 so that it presses a printing sheet against the feed roller 23 in accordance with the linear motion of the rack member 47. When the contact pressure between the printing sheet and the feed roller 23 due to a pressing motion exceeds a predetermined value, a clutch 46 releases the operational coupling between the pinion 45 and the paper feed motor. As a result, the printing sheet is pressed against the feed always by a constant contact pressure irrespective of the amount of loaded printing paper, and therefore, the paper sheets may be fed surely one by one under a constant contact pressure.

Abstract: PURPOSE:To obtain a guidance system which is easy to construct and maintain by detecting two kinds of markers and sending a signal which is modulated according to the kind by radio, and reproducing guidance information selected among plural pieces of sound-recorded guidance information based on time variation of the modulation as a sound and annunciating the information. CONSTITUTION:A detector (walking stick 5) detects markers B and sends a modulated signal B by radio. When a walker passes a point P, a signal that a guidance device 7 receives changes from the signal B to a signal A. For the purpose, the signal of a receiving antenna 6 is monitored to know the moment when the walker passes the point P and the direction of the passage. A logical processing circuit incorporated in the guide device 7 decides that right after the walker passes the point P, and desired guidance information is selected among pieces of recorded guidance information and sent from a transmitting antenna 8 by radio. This sent signal is received by a receiver and listened to as a sound. Markers are made preferably of bad conductor magnetic materials or metal and discriminated by variation in the inductance of a coil sensor.
