Title: Image forming device
Inventor: WATANABE JUNJI
IPC: G03G21/20
Filed: 1990-01-25
Abstract: PURPOSE:To prevent rise in the interior temperature of the main body, to prevent the degradation of image quality, and also to prevent the deterioration of environment around the main body by eliminating the need for providing a sucking means in a main body, and discharging air in the main body into a device base with the use of a sucking means provided in the device base. CONSTITUTION:When copying is started by turning on a copying button, the processes of electrification, exposure, development, transfer, and peeling are performed attending on the rotation of a photosensitive drum 21. A sheet P having a toner image thereon is ejected onto a paper ejection tray 48 via a fixing device 30. A drum 17 passes through a cleaning device 28, therefore the subsequent copying can be carried. While copying is carried out successively, air in the copying machine main body 10, which is heated by the lighting of an exposure lamp 23a or the heating of the fixing device 30 is sucked by a cooling fan 50 as shown by an arrow st. The air is discharged from the openings 51a and 51b of a duct 51 into the inside of the device base 11 as shown by arrows (v) and (w). Thus, rise in the interior temperature of the main body can be prevented, and the degradation of image quality can be prevented. Additionally the deterioration of a surrounding environment, which is caused by exhaust air and noise, can be prevented.

Abstract: PURPOSE: To make possible the focus detection of the subject of a wide luminance region including low luminances as well with a miniature constitution by changing over self-scanning type photoelectric transducer groups alternately for luminance modulation and luminance detection.  
     CONSTITUTION: When a luminance detecting-modulating changeover circuit 16 becomes high level output, a semiconductor switch B 2  and a semiconductor switch B 1  connecting to an inverter go ON and OFF respectively and the outputs of AND gates A 1 , A 6 ... become of low levels, causing semiconductor switches S 1 ... to go ON and S 0  to go OFF, and preventing reverse bias from being applied to the photo diodes d 1 ... constituting the self-scanning type photoelectric transducer groups. Thus, the subject luminance is detected by the current corresponding to the overall luminance. According to this detected luminance, the scanning time, etc. of the circuit 1 are adjusted by way of a luminance modulating circuit 17. When the output of the circuit 16 inverts, it similarly becomes the focus detection operation in which the luminance at every scanning point corresponding to the diodes d 1 ... is well detected over a wide range region of the subject luminance.

Title: Antenna
Inventor: HIYOSHI TOKUKAZU
IPC: H01Q1/42
Filed: 1987-01-26
Abstract: PURPOSE:To reduce the size of the motor by providing a driver to drive a reflecting plate or a radiator horizontally and covering the surrounding the reflecting plate or the radiator by a dielectric made cylinder so as to decrease the drive torque due to the wind pressure. CONSTITUTION:A cover 4 is fitted to a pedestal 3 at a position where the drive center of the antenna and its center shaft are made coincident via a bracket 5. The reflecting plate 1 is fitted to the pedestal 3. The load due to wind pressure exerted to the antenna acts on the surface of the cover and symmetrical to the left/right with respect to the drive center line 6 of the antenna, then no wind pressure torque is caused. Thus, in selecting the motor capacity, only the mechanical friction torque of the drive part bas only to be taken into consideration as the load torque, then the small sized motor is employed. Through the motor size reduction as above, the small size and light weight of the pedestal and power consumption saving are attained.

Title: Optical element
Inventor: MOMOZAKI EIJI
IPC: G02B27/30
Filed: 1983-02-03
Abstract: PURPOSE:To obtain a parallel light which scarcely contains noise and has reliability without executing an adjustment by a small-sized optical element by using an LD integrated type optical element by which an optical waveguide bocomes a dielectric and a collimator lens becomes a concave mirror. CONSTITUTION:A mount position of an LD, namely, size of F is determined by a refractive index (dielectric constant) of a dielectric and a shape of a curved surface of a metallic reflecting film 3. The curved surface shape requires a secondary curved surface in order to eliminate an aberration. The length of F is determined by a numerical aperture 3 and the width of a concave mirror. The width is set to 4mm.. For instance, when the numerical aperture is set to 0.5 and 0.2, F become 3.5mm. and 9.8mm.. In the concave mirror, when a light is emitted from the LD, a return light is naturally generated to the LD. The light emission intensity distribution is a Gauss distribution, and a pretty intense light is returned to the LD. When the return light exists, it is desirable to oscillate a multiple mode whose S/N ratio is good relatively, and it is desirable to return stably an intense return light in order to oscillator stably the multiple mode. In a concave mirror optical element, the LD is positioned centering around the optical axis and there is a large return of optical intensity, and it can be stabilized.
