Title: Color original reader
Inventor: FUCHIGAMI TAKESHI
IPC: H04N1/04
Filed: 1991-10-21
Abstract: PURPOSE:To generate an accurate picture signal without an error in each component without complicated configuration by forming an image of a light of plural color components extracted by a color separate means having a different transmission rate of each color component at a prescribed rate to a photoelectric conversion means. CONSTITUTION:A reflected light from a light source 1 is reflected in a mirror 3, a color filter 4 is used to separate the light into red, green and blue components and the image of the light of each component obtained by the color filter 4 is formed on a line image sensor 6. The color filter 4 consists of a filter R, a filter G and a filter B and the type of material and the thickness of the filter are properly adjusted depending on the spectrum sensitivity characteristic and the spectrum distribution characteristic of the light source 2 and the transmission rate is relatively made different to cancel the ununiformed spectrum distribution of the light source 2 and the spectrum sensitivity of the line image sensor 6. Thus, an accurate picture signal is obtained without a correction circuit.

Title: Safety device for bicycle
Inventor: KAWANABE TETSUYA
IPC: G01S15/93
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To enhance safety of a bicycle by detecting a vehicle that approaches the bicycle from behind and receiving an approaching vehicle signal output through an analysis of a signal provided by an approaching vehicle detecting means, thereby generating an alarm for the rider. SOLUTION: A phototransistor 3 is installed to a seat post 1a of a bicycle 1 as a sensor. The sensor 3 is installed so that it faces backward to detect light emitted by headlamps of a vehicle. An output from the sensor 3 is input to an information-processing unit 4 which performs arithmetic operations of changes in the output and color temperature of the emitting light to determine whether the vehicle headlamps are approaching. The resultant signal is applied to an alarm generator 5 which, if a vehicle is approaching, triggers a buzzer or other warning device to warn the rider that a vehicle is approaching. This allows the rider to know that a vehicle is approaching from behind, contributing to an enhanced safety in bicycle riding.

Filed: 1988-10-28
Abstract: PURPOSE:To easily obtain a composite material having high strength and toughness and complicate shape by heating and softening a raw glass for crystallized glass, forming the raw glass together with ceramic fibers or whiskers under the viscous flow of the glass and crystallizing the formed glass. CONSTITUTION:A composite compound or a laminate of (A) a raw glass for crystallized glass used as a matrix raw material and (B) ceramic fibers or whiskers is used as a molding preform. The preform is heated at a temperature above the softening point of the raw glass for crystallized glass and a temperature to enable the viscous flow of the raw glass. The preform can be easily formed into a prescribed form in a short time by this process. After the molding, the raw glass for crystallized glass is converted to a crystallized glass by a crystallization treatment such as heat-treatment or ultraviolet irradiation. A ceramic composite material having complicate shape and impossible to be produced by conventional high-pressure sintering of ceramic powder can be easily produced in a short time by this process. Most of the produced materials can be used without finishing operation.

Title: Lighting controller of automatic vending machine
Inventor: SANO KAZUO
IPC: G07F9/00
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To prevent the vending efficiency from decreasing owing to a burned- out fluorescent lamp by making an arithmetic control part compare time zone data with current time and controlling the illumination of a lighting device, and further turn on the lighting device when a door is opened not in a lighting time zone. SOLUTION: The arithmetic control part 6 reads the current time data out of a timer 3 and compares the data with the time-zone data stored previously in a storage part 5 by an operation means 5 to control the lighting of the lighting device 1 by turning off an output to a relay 2 unless the current time is within the time zone indicated by the time zone data and turning on the output to the relay 2 when the current time is in the time zone shown by the time zone data. Further, if the door is opened not in the time zone, the arithmetic control part 6a reads in data indicating that the opening of the door is detected from a door opening detecting means 7 and turns on the output to the relay 2 to make the lighting device 1 turned on. Consequently, the decrease in the vending efficiency due to a burned-out fluorescent lamp can be prevented.

Title: Spur in sheet-material conveyor
Inventor: KAWAGUCHI KOICHIRO
IPC: B65H5/06
Filed: 1991-10-21
Abstract: PURPOSE:To prevent the ink transfer and slip at the tip of a spur to contrive to secure a printed surface also at the time of using a recording medium with inferior fixing properties by forming the contact part with printed surface of the tip of the spur of a conveying and discharging part of paper as one of various recording media through etching and further by increasing the hardness of the metal surface of the spur through a surface treatment such as nitriding. CONSTITUTION:Ink printed by a printing part 30 is not surely fixed within the distance A from a spur 9, and when the ink stuck to the projection 9a of the spur is brought into contact with an other-colored, still wet recorded surface in the case of a color printer, the ink runs to cause a printing stain. Therefore, when the spur is formed by etching, a tooth tip can be made small and no burrs appear because it is not pressed. Further, the plate thickness of a metal spur formed by etching is 0.1-0.2mm and also the curvature of the tip is very small as R 0.08mm and less. A surface treatment is applied to this etched SUS material so that the wear resistance relative to coated paper is improved more. Thus, when the wear resistance is required, the spur is subjected to nitriding or soft nitriding and further to carburization so that its surface hardness reaches HV1000.

Abstract: PURPOSE:To overlap sheets easily and reliably and to protect the sheet from damage, by touching sheets being fed out with high speed softly by means of a stop belt, a catch belt and a low speed conveyor. CONSTITUTION:A sheet 11 being projected from a high speed conveyor 22 through a projecting device 12 passes through a guider plate 13 then held by a stop belt 14, a catch belt 52 and a low speed conveyor 16 and overlapped. Said catch belt 52 is entrained over a drive roll 33, an eccentric roll 53 for regulating the lead-in angle (alpha) with respect to the low speed conveyor, a guide roll 17, etc., and since the sheet 11 is brought in contact with the inclined face of the catch belt 52, impact is dispersed. In order to protect the sheet from damage and pressure due to the guide roll 17, a referential roll 54 is set to be slightly higher than the horizontal level. Consequently, the sheet can be overlapped reliably without causing impact damage at the tip of the sheet.
