Title: Correction system for magnetic head position of magnetic recorrding and reproducing device
Inventor: UZUHARA CHIKAHIRO
IPC: G11B21/10
Filed: 1985-06-21
Abstract: PURPOSE:To eliminate the position shift of a magnetic head by providing a part where a magnetic head positioning signal is written on a magnetic medium. CONSTITUTION:When data is read out of or written on the optional track of the magnetic medium 1, magnetic heads 7-9 are moved to the outermost periphery of the medium 1 and positioned at a fine part 3. Then, when the outputs of magnetic head positioning signal tracks 4 and 6 are smaller than the preset level of a playback level comparing circuit 11, it is judged that there is not history of data, and a positioning signal is written on tracks 4 and 6 only at the fine part. Further, when data is written on an inner peripheral surface side of the medium 1, the heads 7-9 are moved on the basis of the tracks 4 and 6 at the part 3. Then, when the outputs of the tracks 4 and 6 are larger than the set level of the circuit 11, it is judged that there is the history of data on the medium 1. In this case, the heads 7-9 are moved according to the output of a 4 and 6 playback level comparing circuit 12 and corrections are made until the outputs of the tracks 4 and 6 become equal to each other.

Title: Controller for vehicular automatic continuously variable transmission
Inventor: SAKAKIBARA SHIRO
IPC: B60W10/10
Filed: 1988-05-31
Abstract: PURPOSE:To prevent the generation of another slip by controlling a speed change operating means in the title transmission, based on the signal of a target torque ratio which is corrected in such a way as to eliminate the slip with a correcting quantity setting means. CONSTITUTION:A target torque setting means 121 in a control part 120 sets a target torque ratio in such a way as to match the maximum power characteristic or optimal fuel consumption characteristic and a speed change operating means 100 controls a continuously variable transmission 1. In this case, as a detecting means 141 detects the slip of a driving wheel W, a torque ratio changing means 122 lowers the torque ratio so as to transmit the torque ratio in the state of non-slippage to a correcting quantity setting means 123. Thus, the correcting quantity is set based on a predetermined characteristic so as to correct the target torque ratio. In this case, based on the signal of a torque ratio changing limit setting means 142, the torque ratio changing means restricts the torque to be the predetermined minimum value or less. As the target torque ratio is changed, a setting means 125 delays an operation speed and a lock-up control releasing means 126 restricts the operation of a lock-up clutch 12.

Abstract: PURPOSE: To reduce the stress sloping generated in the cladding tube in the facing parts to the boundary of fuel pellets in different ray output density, by means of combining the pellets of at least one differential in the concentration degree and the poison concentration degree of neutron.  
     CONSTITUTION: The fuel pellet 7 larger in ray output density than a relatively low fuel pellet 2 of ray output density is cut at both terminal surface by thermal expansion quantity of the pellet due to the difference of ray output density with the adjacent fuel pellet 2. That is, the range occupied by the constituted material of the fuel pellet 7 is smaller than the range occupied by the constituted material of the fuel pellet 7. The fuel pellet is deformed into a hand-drum shape by the thermal stress in the inner part of the pellet when output is raised, and the projections called as ridges 9 are generated at the both end surface of the pellet, thereby fuel cladding tube 3 is pushed by this, and the stress is generated to the cladding tube 3. Therefore, the end surface may previously be cut as shown in the pellet 7.

Title: Ultrasonic humidifier
Inventor: IWAHASHI HIROSHI
IPC: F24F6/12
Filed: 1985-06-20
Abstract: PURPOSE:To indicate the accurate humidity to users by connecting respective light emitting elements that indicate the present humidity by selectively emitting light with an element that controls the ON/OFF of a humidifying unit at a set humidity via multiple switches for setting the humidity so that the humidifier may be controlled by using the signal of the indicated humidity to eliminate the difference between the indicated humidity and the control. CONSTITUTION:For instance, when the power source switch 24 of a ultrasonic humidifier is turned on below the humidity of 30%, the humidification is started upon applying the voltage to an oscillating unit 13, a piezoelectric transducer 14 and a blower fan 7. At this time, the LED25 is being illuminated. When the humidity exceeds 35% by being humidified, the LED26 is also illuminated by the action of IC 34, and a signal is inputted to a transistor 38 via contact points of a humidity setting switch 30. The transistor 38 is electrically connected to the oscillating unit 13, and, when the signal is inputted to the transistor 38, the operation of the piezoelectric transducer 14 is stopped to case humidifying. Then, the humidity in the room gets lowered, and, when the LED26 is turned off, the humidification is resumed. In the case when humidity setting switches 31, 32 are pressed down, although the controlled humidification level is changed, the procedures remain the same.
