Title: Thermal head holder
Inventor: SATO TAKESHI
IPC: B41J25/304
Filed: 1986-05-19
Abstract: PURPOSE:To improve the replacing workability of an ink sheet by providing a holding member rotatable between a first position for pressing a thermal head against a platen and a second position for separating the thermal head from the platen and a member for positioning the holding member. CONSTITUTION:When a holding member 23 is at a first position, a cam follower 14 is contacting against an eccentric cam 15 so as to determine the first position, thereby the downward energizing force is born by the shaft 24 of the eccentric cam 15 and the holding member 23 does not move from the first position. Consequently, even if the back tension is increased, the pressing force of a thermal head 1 against a platen 7 does not drop thereby a stable print quality can be obtained. When the eccentric cam 15 is rotated so as to contact the cam follower 14 against a cam face 15b, the holding member 23 rotates downward around a shaft 3 to the second position, and since a thermal head supporting board 22 follows to the holding member 23, the thermal head 1 and the guide rollers 9, 10 are separated from the platen 7 thus facilitating the replacement of an ink sheet 5.

Title: Electric conduction head
Inventor: TAGUCHI NOBUYOSHI
IPC: B41J2/32
Filed: 1989-05-08
Abstract: PURPOSE:To perform a high-speed, high-sensitivity full color recording by a method wherein in an electric conduction head formed by embedding electrodes in an insulating substrate a high-resistant, heat-resistant, lubricating layer is formed at least on the surface of the electric conduction head made of the electrodes and the insulating substrate. CONSTITUTION:In an electric conduction head 2 having, e.g., a pair of electrodes 23a, 23b opposed to each other, the application of a signal voltage between the electrode pair 23a, 23b causes an electric current to flow through a high- resistant, heat-resistant, lubricating layer 5 of the upper part of the head 2 vertically to the layer and further through a resistant sheet 11 in parallel to the sheet. Joule heat can be mainly generated in the resistant sheet 11 by its resistance value design. At this time, the high-resistant, heat-resistant, lubricating layer 5 on the surface of the electrodes plays the role of preventing an oxidative deterioration during recording and running. A recording head capable of preventing the convergence of a current density in the resistant sheet 11 and suitable for a gradation recording is formed. Moreover, the lubricating properties of the surface of the head 2 realize a stable recording and running without the occurrence of wrinkles in the resistant sheet 11.

Title: Chirped pulse compressing device and chirp pulse amplifying device
Inventor: GALVANAUSKAS ALMANTAS DR
IPC: G02F1/377
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To provide the chirped pulse amplifying device which is simple, inexpensive, and small-sized. SOLUTION: The limits of maximum pulse energy can be evaded by arranging quasi-phase synchronous(QPM) crystal 40 with chirped cycles. The crystal 40 generates a secondary higher harmonic in a single element and pulses expanded by a chirped Bragg grating 20 can be compressed. This constitution makes the device simple and small-sized and the energy of obtained extremely-short pulses substantially increases. Further, the use of this QPM crystal 40 makes possible the variable compensation of a linear and a nonlinear frequency chirp of the secondary higher harmonic. This property is used to make it possible to design the chirp pulse amplifying device which is inexpensive, small-sized, robust, and simple and outputs extremely short pulses.
