Title: Slide-rule device
Inventor: NAKAI TATSUAKI
IPC: G01B21/02
Filed: 1979-05-12
Abstract: PURPOSE: To obtain a simple and light device of compact sized slide-rule with a high reliability employing a nonmagnetic material for the base whose surface is coated with a magnetic paint, and a resin coat is applied on the surface of the paint for protection.  
     CONSTITUTION: This invention relates to a method in which the position of the sliding scale is allowed to be determined by delivering and rewinding it from the drum in the device employing a magnetic detector. The linear nonmagnetic base 2 of the scale is coated on the circumference with a magnetic ink 3 at a fixed space to make a magnetic gradiation and a resin coat 4 is applied on the surface of the ink 3 to prevent the exforiation of the ink 3 while making the sliding smooth during the winding. Guided with a guide section 5, the scale 1 is wound with a drum 6. The magnetic detector 7 is mounted 0.5mm separated from the sliding position of the scale 1, and generates pulses every pitch each time the magnetic ink 3 passes slinding. The pulses are counted to indicate the movement of the scale on the display 8. Thus, the stable result can be obtained because the detection output is independent of the movement speed of the scale 1.

Title: Write protective circuit
Inventor: SUGIMOTO MASAHIKO
IPC: G06F21/79
Filed: 1990-03-09
Abstract: PURPOSE:To prevent unrequired data written on an EEPROM by controlling the feasibility/infeasibility of write of data on the EEPROM by decoding the high-order bit of the data. CONSTITUTION:When the data is the one not requiring the write on the EEPROM 5, a decoder 16 outputs '1' by allocating a specific value on the high-order bit of the data by a CPU 1, and an OR gate 17 is closed, and no write command is transmitted to the EEPROM 5. Meanwhile, when the data is the one requiring the write, the decoder 16 outputs '0', and the OR gate 17 is opened, then, the write command is transmitted to the EEPROM 5. As a result, the data can be written on the EEPROM 5 from a bus transceiver 15. In such a way, it is possible to prevent the unrequired write on the EEPROM 5 performed.

Title: Fsk demodulator and fsk demodulation method
Inventor: OGAWA YUKIO
IPC: H04L27/144
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To accurately discriminate a mark and a space at a lower sampling frequency and to reduce distortion by calculating a time between zero cross points based on a value at a sampling point. SOLUTION: A storage means 3 stores a sampling point period where a sign of a sampling value changes from a negative into a positive value (or vice versa) as a period where a zero cross point is in existence on a time base. A cross point arithmetic means 4 calculates a cross point between a line segment tying each sampling point at both ends of the stored sampling point period and the time base. Then a time arithmetic means 5 calculates a time from the sampling point by using the calculated cross point as a zero cross point. A calculation means of the FSK demodulator 1 is made up of the means 3, 4, 5 as above.

Abstract: PURPOSE:To copy a floppy disk having the capacity larger than the allowable value of an internal memory by using both external and internal memories to transfer the contents of the floppy disk. CONSTITUTION:The capacity of an original floppy disk 4 and the capacity allowable to an internal memory 2 are checked and compared with each other. If the capacity of the original disk 4 is larger than that of the memory 2, an external memory 3 is used. At the same time, the contents of the original disk 4 are sent to the memory 2. In case the memory 2 has no idle space, the remaining contents are sent to the memory 3. Then the contents of the original disk 4 are transferred to a copy disk 4 from the memory 2. When the transfer is through with the contents of the memory 2, the contents of the memory 2 are sent to the copy disk 4 from the memory 3. Thus it is possible to copy a floppy disk having the capacity larger than the allowable value of an internal memory.
