Title: Outer diameter measurement of vulcanized long-sized object
Inventor: ABE FUMIHIKO
IPC: G01B11/08
Filed: 1985-02-27
Abstract: PURPOSE:To enable highly accurate measurement of the outer diameter, by making light from a light source transmit through two measuring windows to capture the transmission light with a photosensor. CONSTITUTION:A vulcanizing tube 1, measuring windows 2 and 3, a photosensor 6, a vulcanized long-sized object 7 and the like are arranged. Light emitted from a light source 4 is transmitted through measuring windows 2 and 3 of the vulcanizing tube 1 to be incident into a sensor 6 through a lens 5. On the other hand, an unvulcanized long-sized object extruded from an extruder is introduced into the vulcanizing tube 1 and vulcanized to make a vulcanized long-sized body 7. When the long-sized body 7 comes between the windows 2 and 3, a shadow is generated on the sensor 6 as light is intercepted thereby. The sensor 6 is made up of a number of photodiodes (PD) on the same surface and a smaller signal output is produced from the PD corresponding to the shadow part on the sensor 6. Thus, the outer diameter of the long-sized body 7 can be determined by counting and computing the number of PDs small in the electrical signal output of the sensor 6.

Title: Power-supply stabilization circuit and capacitor
Inventor: WACHI MASATADA
IPC: H01G11/66
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To obtain a power-supply stabilization circuit which prevents a capacitor from being damaged any more even when the capacitor is damaged by a method wherein a fuse which is blown due to the generation of an overcurrent is installed in series with every capacitor connected across power-supply lines. SOLUTION: A power switch 12 is installed at the positive electrode on the side of an electronic apparatus, and a fuse 15 which is blown when an overcurrent flows (e.g. which is blown at 50 to 100mA) is installed at the positive electrode on the side of an input terminal. When the power switch 12 is turned on, a circuit is started. At this time, when one out of two capacitors 10 is damaged, the resistance value of the damaged capacitor 10 becomes identical to the resistance value of a magnetic dielectric inside the capacitor 10, and an overcurrent flows to the fuse 15. Then, the fuse 15 is blown so as to be set to a state identical to a state that the power switch 12 is turned off. Consequently, it is possible to prevent the overcurrent from flowing to the damaged capacitor 10.

Title: Shutter device interlocked with wind vane to prevent reversal flow for rooftop ventilation fan
Inventor: KAWAI YUZO
IPC: F24F7/02
Filed: 1987-02-21
Abstract: PURPOSE:To naturally ventilate the indoor air at a high efficiency by the attraction of outside air flowing along the shutter even when the fan motor is stopped by rotatably fitting the shutter having an integral windshield to the upper rim of a ventilation duct which contains the fan motor, and fixedly attaching the base of the shaft, which has a wind vane fixed to its upper part, to the shutter. CONSTITUTION:When a wind vane 11 rotates leewardly because of wind, the windshield 16 of a shutter 1 which rotates together with the wind vane 11 also rotates leewardly, and so, the windward outside air is cut off by the windshield 1b and does not flow into the building from a ventilation duct 2. The indoor air is guided to the side top 1a of the shutter 1 by the rotation of a fan 4a, and is ventilated from the opening formed under the side top 1a through a ventilation passage formed in the space between the top cover 7 and the ventilation duct 2. When the fan motor 4 is stopped, since the outside air is sucked into the ventilation passage to be guided to the outside of the windshield 1b of the shutter and flows back to the ventilation passage through the opening formed under the side top 1a, the indoor air in the ventilation duct 2 is sucked out of the ventilation duct 2 for effective, natural ventilation.

Title: Text retrieval device
Inventor: KOYAMA TAKEHIRO
IPC: G06F17/27
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To prevent the omission of retrieval at the time of executing a fuzzy retrieval. SOLUTION: A retrieval character string developing part 10 generates a substitution character string obtained by substituting an erroneous recognition permission character '#' for a part of the character string. The number of erroneous recognition permission characters is determined in accordance with a matching degree designated by an input part 4. A matching part 12 can detect a candidate character string containing an error character by considering '#'as one arbitrary character. Then, '#' is considered to be two arbitrary characters or '##' is considered as one arbitrary character. Thus, the candidate character string generating erroneous division and erroneous connection can be detected in character recognition for generating the text of a retrieval object.
