Title: Mold release device
Inventor: AOSHIMA KAZUO
IPC: B29C45/40
Filed: 1994-02-28
Abstract: PURPOSE:To automate mold release operation while performing swiftly mold release without hurting a molded product, by a method wherein one end diameter of the molded product is contracted by a chuck and the outside of the molded product is pushed up by making use of a pin. CONSTITUTION:When injection molding comes to an end, a molding tool is broken and the molding tool 1 to which a molded product 2 is stuck is fixed to a mold release device. At this time chucks 3, 3 are at an open position and pins 4, 4 are at a lower limit position. Then the chucks 3, 3 are clamped and they are allowed to hold the lower end of the molded product 2 and to contract the diameter of the same. Hereby, a part of the molded product lower than the small-diameter part 2a is peeled off from the molding tool. Then the pins 4, 4 are raised and the outside of the molded product 2 is pushed up as the diameter of the lower end of the molded product 2 is contracted by the chucks 3, 3. At this time the pins 4, 4 pass through semicircular notched parts 3a, 3a formed on the chucks 3, 3. Then it becomes that a part of the molded product upper than the small-diameter part 2a of the molded product 2 is peeled off from the molding tool 1 by the pins 4, 4.

Title: Camera capable of obtaining fantasy effect
Inventor: KAGEYAMA NAOHIRO
IPC: G03B7/00
Filed: 1990-02-09
Abstract: PURPOSE:To separately set exposure and the degree of a fantasy effect by superposing a focused image and a defocused image by moving a lens while performing multiple exposure and performing the movement of the lens separately from the exposure. CONSTITUTION:The focused image is superposed on the defocused image by moving the lens 5 by a lens driving circuit 8 while performing the multiple exposure, and the movement of the lens 5 and the exposure are separately performed. Namely, a photographer executes the multiple exposure at a focused position and a position where a focusing position is automatically diverged by a certain quantity from the focused position and the focusing position is allowed to be diverged while performing the multiple exposure. Therefore, the exposure and the degree of the fantasy effect are separately set. Thus, the fantasy effect is prevented from being restricted by photographing brightness and the degree of the fantasy effect is freely set.

Title: Optical detector
Inventor: KANBE YOSHIAKI
IPC: G01S17/04
Filed: 1984-02-20
Abstract: PURPOSE:To detect whether bodies to be detected different in reflection factor are present or not and to measure its movement distance through simple constitution without malfunction by calculating the ratio between direct reflected light and diffuse reflected light. CONSTITUTION:Light from the projection means 11 of an optical fiber illuminate the body 15 to be detected through a self-converging lens 14. Then, the direct reflected light and diffuse reflected light are photodetected by the 1st photodetecting means 12 and the 2nd photodetecting means 13 of optical fibers. Detection outputs of those means 12 and 13 are processed by coordinate amplification, subtraction, etc., to determine the ratio between the direct reflected light which does not vary in reflection factor and the diffuse reflected light, thereby detecting whether the body to be detected which has a different reflection factor is present or not without malfunction. Further, the center of the diffuse reflected light passes through an optical axis g2, and the movement of the body to be detected causes variation in not the quantity of the diffuse reflected light, but only the quantity of the direct reflected light, so the movement distance of the body to be detected is measured. Further, optical fibers for projection and photodetection need not be supported at some angle, and the constitution of the optical detector is reduced in size.

Title: Oscillation circuit system, modulation system, demodulation system and multilevel qam modulation/ demodulation system
Inventor: TANAKA SHOTARO
IPC: H04N21/438
Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To realize a PLL synthesizer reducing the phase fluctuation of an oscillation output in spite of receiving vibration by setting a phase comparing frequency generated by frequency-dividing the oscillation output of a crystal oscillator to be equal to or larger than a specific value. SOLUTION: One element deciding the phase characteristic of the oscillation output 110 is the phase comparing frequency set by a reference frequency divider 106. The phase comparing frequency is a frequency for sampling the phase error of respective frequency dividing signals from a programmable frequency divider 108 and the divider 106. By setting this phase comparing frequency to be at least 250 kHz, the phase fluctuation of the oscillation output of a VCO part 104 is corrected by a short time period at a PLL synthesizer IC part 102 and feedback control becomes possible. As a result, it becomes possible to reduce phase fluctuation at the output 110 in the PLL synthesizer.
