Abstract: PURPOSE:To obtain an electrothermal printing head capable of being adapted for higher density and a multiple-electrode construction, by providing small-type electrothermal heads shorter than the width of a paper to be used, and arranging the electrothermal heads in parallel over the entire range of the width of the paper. CONSTITUTION:Each electrothermal head 26 constituting an electrothermal transfer head 1 comprises two current-controlling ICs 32 on a flexible printed board, and a current-passing part 36 comprising electrode patterns 34 corresponding to a printing resolution for printing on a paper 5 which part 36 is provided at the tip of the head 26. When being supplied with a code signal through a connection part 38, each of the ICs 32 analyzes a code, and passes currents to the electrode patterns 34. When each of the electrothermal heads 26 receiving a driving controlling signal from an electronic controller 20 through a connector 15 passes the currents to the corresponding electrode patterns 34, an electric current flows through a closed circuit comprising an electrothermal transfer sheet 9 and a return electrode roller 13 at the current-supplied part, thereby effecting local heat generation in the sheet 9 and transfer to the paper 5.

Title: Magnetic head device
Inventor: HOSOYA KOICHI
IPC: G11B5/31
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To make it possible to prevent an uneven wear of the sliding surface of a magnetic recording medium and to obtain good electromagnetic transducing performance by forming a surface to be faced by a magnetic head part and a hard carbon film as the sliding surface of the magnetic recording medium. SOLUTION: The magnetic head part 3 is formed on an alumina film 10 which is an under-coating layer 8 formed on an AlTiC substrate 7. As a result, the insulation between thin-film coils, the electrodes of an MR elements, etc., and the AlTiC substrate 7 is assured. The magnetic head part 3 is formed on the under-coating layer 8 and is then covered with a diamond-like carbon(DLC) film 9. The alumina film 10 is formed to cover the DLC film 9 and constitutes the one end of the magnetic head device. Since the AlTiC substrate 7, the magnetic head part 3, the DLC film 9 and the alumina film 10 face the sliding surface 1a, a magnetic tape polishes these. Since the hard DLC film 9 is formed so as to cover the magnetic head 3, the uneven wear of the sliding surface 1a is prevented.

Title: Vertical picture reduction device
IPC: G09G5/18
Filed: 1992-03-31
Abstract: PURPOSE:To correct unnaturality of a reduced picture by detecting a field and controlling a write signal in response to the vertical reduction rate to store interleaved sampling data to a memory. CONSTITUTION:A vertical synchronization pulse generated by a vertical separator circuit 8 is fed to a field discrimination circuit 9 and an offset circuit 30. The field discrimination circuit 9 discriminates whether a field is an odd number field or an even number field based on the vertical synchronization pulse and a horizontal synchronization pulse and sends the result of discrimination to a control circuit 35. Then the offset circuit 30 receives the vertical synchronization pulse and data whose reduction rate is 13 and the vertical synchronization pulse of the odd number field or the even number field is continuously delayed by the reduction rate. Thus, the field is detected and a write signal is controlled depending on the vertical reduction rate and interleaved sampling data are stored in a frame memory 4.

Title: Automatic fishing machine
Inventor: SOGABE SATOSHI
IPC: A01K79/00
Filed: 1988-03-30
Abstract: PURPOSE:To prevent the misconfirmation of unhooking, by changing the unhooking confirmation angle according to the weight of the caught fish. CONSTITUTION:The unhooking confirmation angle calculated by an unhooking confirmation angle operator becomes thetab (the fishing rod 541 is declined to deck- side) when the weight of the caught fish is light. When the fish is heavy, it becomes thetaa (the rod is steeply raised on the deck). The weight of the fish is detected by a fish weight sensor and inputted into an unhooking confirmation angle operator. The throwing back of the fish into the sea by springy force of the fishing rod 541 can be prevented by the above action when the caught fish has light body weight. When the fish is heavy, the bending of the fishing rod 541 becomes large to enable the suspension of the fish above a deck while preventing the contact of the fish body with the deck.
