IPC: G11B20/10
Filed: 1991-02-25
Abstract: PURPOSE:To release the occupied state of a controller without turning off its power source by deciding whether the response signal from the controller for an operation confirmation signal can be received within a certain time or not. CONSTITUTION:When a controller 1 or 3 occupies a magnetic disk device 5, a state confirming circuit 7 periodically transmits the confirmation signal for confirmation of the operation of the controller 1 or 3. The controller 1 or 3 receives this signal by a response circuit 2 or 4. The controller 1 or 3 transmits the response signal to a state control circuit 6 of the magnetic disk device 5. When the response signal is received within a certain time after transmission of the confirmation signal, the state control circuit 6 keeps the occupied state due to the controller 1 or 3 as it is. If the response signal cannot be received, the control circuit 6 releases the occupied state of the magnetic state 5 due to the controller 1 or 3. Thus, the magnetic disk device can be accessed by another controller (omitted in the figure).

Title: Shading correction method for picture information reader
Inventor: GOTO CHIAKI
IPC: H04N1/113
Filed: 1985-02-18
Abstract: PURPOSE:To eliminate the streaky shading by obtaining the shading characteristics of a condenser prior to the reading of light out of a recording medium and with resolution higher than a digital read signal and giving the correction to an analog read signal before its digitization in accordance with its shading characteristics in a light reading mode. CONSTITUTION:The radiant rays such as X rays, etc. of even intensity are irradiated on a storage type fluorescent sheet 10 before the radiation picture information is read. Then the sheet 10 is loaded to a picture reader. Here a reference output signal SO delivered from a photomultiplier 17 is supplied to an A/D converter 30 with changeover of a switch 22 and converted into a digital signal with the bit resolution sufficiently higher than a digital read signal Sd. This digital signal is supplied to a correction value arithmetic circuit 31 and the difference is obtained for each picture element between said digital signal and a reference output signal SdO of the direction along an incident end surface 16a. When the radiation picture information is read, a shading correction circuit 23 reads the correction value out of a memory 32 for execution of correction. In this case, the signal Sd has no variation more than the proper correction value owing to the shortage of resolution. This prevents the generation of the streaky shading.

Title: Energy sealing piezoelectric resonator
Inventor: KAIDA HIROAKI
IPC: H03H9/17
Filed: 1993-02-19
Abstract: PURPOSE:To provide an energy sealing piezoelectric resonator to 1-2 MHz band by linking a pair of supporting part to the node point of the vibration of a piezoelectric resonator part utilizing a width mode. CONSTITUTION:A piezoelectric resonator part 2 is composed of a piezoelectric material such as piezoelectric ceramic and provided with structure forming resonating electrodes 2b and 2c on the entire faces of both main faces of a rectangular piezoelectric board 2a, and the piezoelectric board 2a is polarized uniformly so that the polarizing axis can be parallel with the thickness-wise direction. On the other hand, supporting parts 3 and 4 are formed by the same material integrally with the piezoelectric board 2a and linked to a pair of side face central parts, which are faced each other, of the piezoelectric board 2a. Thus, since the supporting parts 3 and 4 are linked to the node point of vibrations, the vibrations caused by the width mode are not almost transmitted to the side of link parts 3a and 4a. Therefore, the vibration energy of the piezoelectric resonator part 2 utilizing the width mode is actually sealed between the supporting parts 3 and 4.

IPC: G11B15/28
Filed: 1984-02-20
Abstract: PURPOSE:To prevent a draw-in phenomenon and the damage of a tape in the tape loading/unloading mode by cutting an upper metal of a capstan, a metal housing and a capstan drop-off preventing member so that they are not protruded to the tape side beyond the capstan tangent line and forming the capstan tip part into a conical shape. CONSTITUTION:A capstan upper metal 17 is cut by about half at the tape side so that it remains only at the side where the press contact force of a pinch roller is received. In the same way, a metal housing 19 and a capstan drop-off preventing member 19a formed at the tip part of the housing 19 are cut by about half like the metal 17. Furthermore, the tip of a capstan 16 is formed into a conical shape. In such constitution, it is impossible to load and unload a tape along the capstan 16 in a tape cassette loading/unloading mode. This prevents the hitch between the tape and the metal 17 and the upper part of the housing 19 and therefore avoids a draw-in phenomenon and the damage of the tape.
