Title: Auxiliary lighting device for focus detection
Inventor: MATSUI TORU
IPC: G03B13/36
Filed: 1986-09-22
Abstract: PURPOSE:To light even a focus detection area shifting from an optical axis and to perform focus detection by widening a lighting range so as to cope with the movement quantity of a focus detection area off the optical axis due to variation in the focal length of a photographic lens. CONSTITUTION:Light which is laterally wide passes through a pattern surface 6 and is projected on a subject by a projection lens 5. The side wall 10 of an LEDb forms a reflecting mirror and light projected from the flank of the LEDb is reflected toward the pattern surface 6 and then projected on the subject. The pattern surface 6 is arranged where pieces of luminous flux of respective LED light emission part overlap one another, bit by bit, and a blind zone where no light reaches is eliminated between areas (r) and (m), and (m) and (r). Thus, lighting areas (m), (r), and (l) are obtained and the lighting area (r) and (l) become wide even in case of the movement of focus detection areas R and L off the optical axis of the photographic lens due to specific variation in the focal length of the photographic lens, so focus detection is performed in the focus detection areas off the optical axis regardless of the focal length of the photographic lens.

Abstract: PURPOSE: To shorten a molding cycle by starting injection of a melt resin into a mold cavity during a mold clamping. CONSTITUTION: In a mold open state, a clamping ram 4 is advanced, and a movable mold 1 is touched on a stationary mold 5. Next, an internal pressure of a clamping cylinder 3 is raised for imparting a predetermined clamping force to the molds (the movable mold 1 and the stationary mold 5).

Title: Waveform encoding device
Inventor: MAEKAWA HIDETSUGU
IPC: G10L19/00
Filed: 1993-09-10
Abstract: PURPOSE:To provide the waveform encoding device which can improve the identification precision of a signal that is semiperiodic and high in nonlinearity and enables the intermediate-period and long-period prediction of signal data. CONSTITUTION:An initial identification function candidate group generation part 2 generates plural identification function candidates and an evaluated value calculation part 3 calculates the differences of the respective identification function candidates from a true value. Plural identification function candidates which are considered to improve evaluation are generated from the result of the evaluated values through processes from an identification function selection part 4 to a parameter variation part 6. Said processes are repeated to obtain an optimum identification function. A signal waveform is identified with the linear sum of the periodic signal, so the identification precision of the semiperiodic signal is improved and the intermediate-period and long-period prediction of signal data becomes possible. Further, a multi-point search is made by using plural identification functions, so the identification precision of a signal can be improved.
