Title: Optical recording medium
Inventor: ITO MASATAKA
IPC: G11B7/004
Filed: 1988-01-06
Abstract: PURPOSE:To enable stable recording and reproducing operations by separating track guide grooves spirally formed on an optical disk substrate from each other and forming said grooves of the respectively plural continuous grooves. CONSTITUTION:This recording medium has the constitution consisting in separating the spirally formed track guide grooves 11A-11C for recording the prescribed information and forming such grooves of the respectively plural continuous grooves on the optical disk substrate 1. The use of optical beams 2A-2C corresponding to the number thereof is, therefore, possible, and the respective track guide grooves 11A-11C are continuous without interruptions from the inside to the outside circumference of the disk 1. The need for track jumping is eliminated even in the case of executing recording and reproducing continuously by using the plural light beams 2A-2C. The stable recording and reproducing operations are thereby obtd. without decreasing the recording capacity.

Filed: 1999-01-06
Abstract: PROBLEM TO BE SOLVED: To provide a head which is a head producible without application of unnecessary heat and has a sliding surface to prevent the adhesion of material, such as a resin, to a tape and a process for producing the same.

Title: Tape driver
Inventor: SUENAGA HARUO
IPC: G11B15/48
Filed: 1981-01-07
Abstract: PURPOSE:To prevent a tape tip from damaging, by inhibiting deceleration control, etc., until the end of the tape is detected during the fast forwarding of the tape. CONSTITUTION:When the end of a tape 3 is detected by a tape-end detector 9 while the tape 3 is fed from an S reel 2 to a T reel 11, a microprocessor 14 turns off an S brake 17 and a T brake 19, and set the driving torque of an S motor 1 and that of a T motor 10 to TS1 and TT1 respectively. Thus, both reels 2 and 11 are applied with the driving torque in the braking directions, so their turning speeds are reduced with time. Then, the supply side S motor 1 and take-up side T motor 10 are controlled independently of each other. During supply, when an S-reel turning-speed detector 15 detects the turning speed of the S reel 2 decreasing below a certain value, the microprocessor 14 turns on the S brake 17 and adjusts the driving torque of the S motor 1 to zero. Therefore, the S reel 1 stops with time.

Abstract: PURPOSE:To perform the batch processing of a half-arrow dimension line indicating the dimension value from X axis, a half-arrow dimension line indicating the dimension value from Y axis, and an angular dimension line by providing a calculation processing means calculating the required dimension line. CONSTITUTION:Dimension line position and both terminal coordinates of the line segment and line segment designating position are inputted from an input means 1 in an arithmetic processing means 2. The arithmetic processing means 2 discriminates whether or not the line segment is parallel to the X or Y axis based on both terminal coordinates of the line segment. When the line segment is parallel to the X or Y axis, the half arrow dimension line indicating the dimension value from the dimension line position is prepared when the line segment is parallel to the X or Y axis. When the line segment is not parallel to the X or Y axis, the terminal point of the line segment generating the dimension line position from a line segment designating position is selected at first. Then the half-arrow dimension line indicating the dimension value from the X or Y axis is prepared at the dimension line position. Further, the angular dimension line corresponding to the line segment is prepared.

Abstract: PURPOSE:To eliminate the useless consumption of second toner by detecting the number of two-color prints and separating and recovering first toner from a second developing device based on the detected result. CONSTITUTION:When the number of two-color prints is counted and the counter value thereof arrives at a prescribed value, the processing of a separation mode is executed. In the separation mode, a photosensitive body 1 is driven. Around the body 1, only a first electrostatic charger 2 and the second developing device 6 are driven and the others are not driven. Besides, potential relation among them is set to be prescribed. Based on generated electrostatic contrast, the red-color toner (first other) intruded in the developing device 6 is attracted to the body 1. On the other hand, the black-color toner (second toner) is not attracted to the body 1 by the electrostatic contrast. That means, the red-color toner mixed in the black-color toner is selectively separated, attached on the body 1 and recovered by a cleaning device 9.

Title: Radio communication system
Inventor: KATAYAMA ATSUSHI
IPC: H04B1/7143
Filed: 1996-01-11
Abstract: PROBLEM TO BE SOLVED: To avoid transmission of erroneous data by measuring a radio wave environment of an available channel, providing a prescribed sequence, informing the sequence to a receiver side and conducting transmission/reception by the frequency hopping method according to the sequence. SOLUTION: When a main control section 704 recognizes a transmission request command, a radio controller 708 receives sequentially radio waves of each channel and measures a highest reception level. When the measurement of all channels is finished the main control section 704 generates an operating sequence of use in the order of better radio wave environment of channels while avoiding the use of bad channels to the utmost and stores the result to a memory 705. A radio control section 708 uses a minimum frequency channel F, and adds a communication destination address to a hopping frame representing the channel operating sequence and sends the resulting frame. The receiver side receives a hopping pattern to recognize the hopping channel sequence. Then the transmitter side switches channels for 5ms each and sends data by using data frames.  When the receiver side recognizes the end of transmission, the receiver side stops the frequency hopping and awaits the succeeding transmission at the channel F1 again.
