Title: Position measurement method and position measurement system
Inventor: HORIUCHI TATSUO
IPC: H01J9/42
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To measure a raster shape of a video display device placed easily with high accuracy. SOLUTION: Measurement points 3a, 3b, 3c are decided on a video display device A and coordinates (X3a , Y3a , Z3a ), (X3b , Y3b , Z3b ), and (X3c , Y3c , Z3c ) in the XYZ coordinate system are calculated. Coordinates (u3a , v3a ), (u3b , v3b ), and (u3c , v3c ) of the image at each measurement point projected on a UV plane is converted into coordinates (x3a , y3a ), (x3b , y3b ), and (x3c , y3c ) on an ideal plane xy. A map function from the coordinate system XYZ into the coordinate system xy is generated by using the coordinates (x3a , y3a ), (x3b , y3b ), and (x3c , y3c ), a distance (calculated in advance) from the ideal plane xy to a lens principle point F and the coordinates (X3a , Y3a , Z3a ), (X3b , Y3b , Z3b ), and (X3c , Y3c , Z3c ) at each measurement point.  An inverse map function from the coordinate system xy into the coordinate system XYZ is generated by using the map function and design information of the video display device A. A raster image of the video display device A projected on the ideal plane xy via the uv plane is inversely mapped onto the coordinate system XY by using the inverse map function.

Title: Device and method for automatically feeding document
Inventor: YAMAZAKI KATSUYA
IPC: G03G21/14
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To suppress the blurring of an image caused by the vibration of a carrying means when a document is read by controlling the driving of the carrying means according to the carrying speed/carrying mode of the document. SOLUTION: Such an action that the document is carried to a platen and read at the same time is the running read action. Then, a wide belt used at this time is driven by a belt motor 102. By the motor 102, the document placed on a document tray 4 is carried to the platen. When the reading speed of the document is low (<=200mm/s), the vibration when the document is read is minimized by using a microstep 2W1-2-phase exciting system. When the reading sped of the document is gradually increased, the exciting system is switched to a microstep W1-2-phase exciting system and a microstep 1-2-phase exciting system.

Title: Semiconductor type radiation measuring apparatus
Inventor: KITAGUCHI HIROSHI
IPC: G01T1/24
Filed: 1992-02-03
Abstract: PURPOSE:To improve a dynamic range in large degree by controlling the thickness of the radiation sensitive part of a semiconductor radiation detecting element in accordance with the measuring rate of measured radiation. CONSTITUTION:Depletion layers 9, 10 to be the radiation detection sensitive parts of a semiconductor detecting element 1 are spread under a p-n joint part 11, and the sensitive volume of radiation detection is obtained from the area of the joint part 11 and the thickness (t) of the depletion layers 9, 10. This thickness (t) depends on applied bias voltage (V). When bias is applied to the element 1, the thickness (t) becomes as large as the depletion layer 10, and the detector becomes high-sensitive. Without bias, the thickness (t) becomes as small as the depletion layer 9, and the detector becomes low-sensitive in proportion to the square root of the voltage V. In thus case, the counting rate during measurement is monitored by a counting rate meter 6. In the case of exceeding the maximum counting rate in the bias applied state, an arithmetic control circuit 7 cuts off a reverse bias applying circuit 2, and in the case of being lower than the minimum counting rate, the circuit 2 is switched into the bias applied state. With this control, the dynamic range of a measuring apparatus is improved in large degree.

Title: User confirmation system
Inventor: NAKAHATA HIROSHI
IPC: G06F21/34
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To confirm whether a user is legal and prevent illegal use. SOLUTION: When a user which bears a data carrier 1 approaches, a reader 4 reads an ID code out of the carrier 1. A judging circuit 7 matches this code against codes registered in a memory 5 to judge whether or not the user is legal. An acknowledgement signal output circuit 8 continues to output an acknowledgement signal as long as the judging circuit 7 judges that the user is legal. A controlled device 3 allows the carrier to be used when inputting the acknowledgement signal. Thus, use by an illegal user whose ID code is not registered can be rejected. Further, it is always judged whether or not use is allowed, no even if the user leaves the device 3 during the use, for example, without turning off the power source, the use by the illegal user can be rejected.

Title: Noise preventing device of on-vehicle radio equipment
Inventor: SONE MASAZUMI
IPC: H04B15/04
Filed: 1983-02-07
Abstract: PURPOSE:To prevent a noise generated by a motor controller from causing a disturbance to an on-vehicle radio equipment by varying the frequency of a duty signal to a frequency where no disturbance to the radio equipment is caused according to the operation frequency of the radio equipment. CONSTITUTION:The tuning frequency of an on-vehicle radio 35 is detected by a tuning frequency detector 36, whose detection output is supplied to a computer 21. The computer 21 generates an air-capacity setting signal S1 which has an amplitude determined by pieces of information from an in-room temperature sensor 37, an outside-temperature sensor 38, and a blow-fan air-capacity adjusting knob 39 and supplies it to a comparator 32. On the other hand, a switch 22d is driven on the basis of a detector 38 which detects a frequency that the radio 35 is tuned to select and output a desired output among outputs of triangular wave oscillators 22a-22c to the comparator 23. The comparator compares the signal S1 with the selected triangular-wave signal S2 and outputs the duty signal S3. Then, the triangular wave signal S2 which has the largest difference between its higher harmonic and the radio tuning frequency is used to minimize a noise to the radio 35.
