Title: Automatic focusing device
Inventor: ARAKI RYOTA
IPC: G02B7/28
Filed: 1987-01-27
Abstract: PURPOSE:To effectively utilize the inside space of a camera to reduce the size of the camera and to improve the detection accuracy of focus detection by branching the luminous flux of a primary imaging path and forming the image magnified by a magnifying lens to a focus detecting element provided in the upper space of a filter. CONSTITUTION:Photographing light is imaged to a focal plate 7 and is reflected by a finder mirror 9 so as to be formed as an aerial image on a secondary imaging plane 12. Said luminous flux is branched by a beam splitter 4 and is entered to the focus detecting element 5. The imaging is enlarged by a concave lens 3 to improve the accuracy of the focus detection. The space around the shutter is effectively utilized by providing the element 5 to this position. Part of the luminous flux is received in a photodetecting part 10 through the half-mirror 9a to measure the luminance of a subject. Photographing information is displayed on the display part 14 of the imaging plane 12 to prevent the incident of light from the display part to the photodetecting part 10. The detecting element 5 and the photodetecting part 10 are provided in the cavity of the camera in such a manner, by which the size of the camera is reduced and the accuracy of the focus detection is improved.

Filed: 1985-02-01
Abstract: PURPOSE:To smooth the sucking and discharging of a solid, by forming the discharge port of a solid discharge pipe for sucking and discharging the solid in the recessed part of a basket into such a shape that the gas in the basket can be always introduced into the discharge pipe. CONSTITUTION:After the removal treatment of a liquid was finished, the solid C formed to the inner periphery of a basket 7 is scraped off by a scraper 21 while the basket 7 is rotated at a low speed and fallen in the recessed part 12 of the bottom part of the basket 7 to be sucked and discharged by a slid discharge pipe 24. The solid C in the recessed part 12 is relatively flowed with respect to the discharge pipe 24 with the rotation of the basket 7 but, because the discharge pipe 24 obstructs the flow of the solid C, a gap part S, where no solid is present, is generated to the lateral side of the front end part of the discharge pipe 24. In this case, a part provided with a gap d2 having a size capable of communicating the gap S with the interior of the discharge pipe 24 is provided to the front end part of a solid introducing port 25 to make it possible to always introducing gas into the discharge pipe 24 along with the solid C.

Title: Casting method for thermoplastic resin sheet
Inventor: AOKI SEIZO
IPC: B29C41/50
Filed: 1990-01-26
Abstract: PURPOSE:To cast a thermoplastic resin sheet which is superior in plane properties, free from surface defect and stable and has little thickness irregularity, by making the diameter of a cooling drum into a specific one or larger. CONSTITUTION:It is necessary that the diameter of a cooling drum is 2.0m or larger, preferably 2.3m or larger, far preferably 2.5m or larger, further prefer ably 3.0m or larger.

Title: Clock interruption detection circuit
Inventor: MATSUMURA SEIYA
IPC: H04L7/00
Filed: 1993-01-07
Abstract: PURPOSE:To accurately detect the interruption of the signals of an optional clock period by generating output for indicating clock signal interruption when the prescribed number of reference clock signal pulses are inputted in a state that clock signals are interrupted. CONSTITUTION:When the clock signals stop at an L level, an H level is impressed to a reset terminal and a counter 2 is reset. Since the L level is inputted to the reset terminal, the counter 1 is not reset and is counted up when the prescribed number of reference clocks are inputted and H level signals are supplied through a decoder 4 to an OR circuit 6. Also, when the clock signals stop at the H level, the counter 1 is reset, however, the counter 2 is not reset and the H level is supplied to the circuit 6 by the counting-up of the reference clocks. Thus, when the output of the circuit 6 is monitored, the clock signal interruption can be accurately detected.
