Title: Picture retrieving device
Inventor: WAKIMOTO KOJI
IPC: G06T1/00
Filed: 1989-07-21
Abstract: PURPOSE:To retrieve plural kinds of input pictures only by indicating one sample picture by converting a feature data, which describes the feature of the sample picture to be extracted, to a feature data of the description in accordance with an interpretation rule, and extracting up a picture which is coincident with a retrieving condition by collating that feature data with the feature data of the input picture. CONSTITUTION:A picture structure interpreting means 8 converts the characteristics data which describes the feature of the sample picture to be extracted by a picture feature extracting means 4, to the described feature data which follows the interpretation rule set by an interpretation rule setting means 7. By collating that converted feature data with the feature data of the input picture stored in a picture feature storing means 2, a picture structure collating means 9 extracts the picture which is coincident with the retrieving conditions. Thus, just by resetting the interpretation rule, a picture that possesses another feature can easily be retrieved even if there is only one sample picture.

Title: Slip control device for fluid coupling
Inventor: NOBEMOTO HIDETOSHI
IPC: F16H61/14
Filed: 1989-07-20
Abstract: PURPOSE:To prevent lowering of engine speed at the time of resuming the slip control of a lockup clutch after terminating acceleration by controlling responsiveness of slip control according to an engine load change rate at that time. CONSTITUTION:The locking force of a lockup clutch is lowered by a control unit 60 at the time of acceleration to place a fluid coupling into converter state and enlarge torque to obtain large accelerating force. Upon terminating acceleration, the control characteristic of the fluid coupling at the time of shifting from the converter state to slip control is controlled in the optimum state according to the load change rate of an engine 10 detected by a throttle sensor 61, for instance the responsiveness of slip control, that is, the shift to slip control, is more delayed as the increase rate of engine load becomes larger. The lowering of engine speed caused by the sudden shift of the fluid coupling from the converter state into the slip state can be thereby avoided, and also the torque enlarging action of the fluid coupling can be obtained.

Title: Thin film transistor
Inventor: SANO YUTAKA
IPC: H01L29/786
Filed: 1988-07-29
Abstract: PURPOSE:To raise the driving frequency of a shift register and to reduce power consumption by forming an active layer for forming the channel of a thin film transistor of nondoped polysilicon, and setting the threshold voltages of N- and P-channel transistors to a predetermined value. CONSTITUTION:An active layer for forming the channel of a thin film transistor is formed of nondoped polysilicon, the threshold voltage of an N-channel transistor is 2V or more, and the threshold voltage of a P-channel transistor is -5V or less. Thus, N-channel and P-channel are composed. The polysilicon active layer is not channel doped, and enhancement-driven even if its n<-> conductivity type remains as it is. If the threshold voltage of the N-channel transistor is less than 2V or the threshold voltage of the P-channel transistor is higher than -5V, the balance of the N-channel and P-channel transistors is broken, and a normal CMOS operation is not conducted. The threshold voltages of the transistors are controlled by limiting the manufacturing process conditions of the transistors.
