Title: Method for identifying validity/invalidity of mark with invisible ink
Inventor: YAMAMOTO MASAMITSU
IPC: B42D15/10
Filed: 1994-11-30
Abstract: PURPOSE: To surely judge the validity/invalidity of a mark by irradiating the mark obtained by superposingly applying a process ink on the surface of a mark printed with an infrared-ray absorbing ink, with infrared rays and visible light. CONSTITUTION: A reading mark 4 such as a bar code is printed on a security 1 and process ink (e.g. red) is superposedly applied on the surface of the mark 4. The mark 4 is irradiated with infrared rays by a 1st light emitting element 5 and its reflected light is received by a light receiving element 7. An arithmetic processor 8 judges the mark 4 as a true one when an absorption rate is maximum at 1000nm e.g. and judges it as a forgery when an infrared-ray area is not absorbed. At the time of judging the mark 4 as a true one, the mark 4 is irradiated with red light by a 2nd light emitting element 6 and its reflected light is received by the element 7. The processor 8 judges the mark 4 as a true one when the red light is reflected at 650nm and judges it as a forgery when the red light is not reflected.

Title: Combustion condition detecting device for internal combustion engine
Inventor: FUKUCHI EISAKU
IPC: G01M15/00
Filed: 1997-10-29
Abstract: PROBLEM TO BE SOLVED: To diagnose a combustion condition such as misfire in a wide operation region by calculating deviations between time signals of two facing cylinders and those of other two facing cylinders, calculating average value of the deviations, correcting the time signals using the average deviation, and detecting a combustion parameter from the corrected time signals. SOLUTION: During engine operation, a rotation speed detecting means 101 in a given angle detects a time (time signal) required for a ring gear to rotate in a given angle. Two rotation speed detecting means 102, 103 for facing cylinders distributes time signals for each of facing cylinders, and a cylinder- group deviation detecting means 107 derives deviations between non-facing cylinders based on outputs from each of means 102, 103. An average value calculating means 104 averages the deviations, and a time signal correcting means 108 subtracts the averaged deviation from the divided time signal. The result is set as a time signal from which effects of manufacturing errors of a ring gear is removed, a combustion condition detecting means 105 detects combustion conditions, and a combustion condition judging means 106 judges the combustion condition.

Title: Liquid container
Inventor: MORIMOTO JUNJI
IPC: A47J41/02
Filed: 1998-10-19
Abstract: PROBLEM TO BE SOLVED: To avoid erroneous packing use in liquid containers whose plug is mounted on its external surface with packing adapted to be pressed on the internal surface of the mouth of their container body to form a seal, by warning users if they carelessly install the packing upside down. SOLUTION: When mounted on the external surface of a plug 3 in place or normally, packing 4 keeps its lip portion 12 freely flexible. If the packing 4 is mounted upside down, on the other hand, the flexibility of the lip portion 12 becomes null to give its wall thickness ΔX direct to the outside diameter X of the plug 3. With the minimum inside diameter Y of a mouth 2 of a container body 1, the outside diameter X and the wall thickness ΔX form a relation represented as X<Y<X+2ΔX, whereupon the inverted packing 4 disables the plug 3 from fitting in the mouth 2.

IPC: G11B21/02
Filed: 1986-12-16
Abstract: PURPOSE:To simplify and miniaturize the composition of a circuit and to reduce the cost by converting the rotary movement of a motor into a linear movement via the speed reduction mechanism linked with the rotary shaft of a brushless motor and driving a pickup by this linear movement. CONSTITUTION:A speed reduction mechanism 3 is rotated as well with the rotation of a brushless motor 1, but at this time a pickup 4 starts to move linearly along a feeding rack 5 with moving a guide 6. Namely the rotary movement of the brushless motor 1 is reduced and converted into a linear movement and the pickup 4 starts to move linearly to enable a tracking control. At this time the driving force of the brushless motor 1 causes no knocking by rotating smoothly from a low rotary speed to high speed rotation and the pickup 4 performs a linear movement smoothly. A retrieval can directly be performed by controlling the brushless motor 1 only and a small sized and inexpensive pickup feeding controller is obtd.
