Filed: 1991-03-08
Abstract: PURPOSE:To display a plurality of pointers on a screen and enable respective pointers to be independently operated respectively. CONSTITUTION:Pointer generating circuits 74a, 74b, 74c generate pointers 73a, 73b, 73c, respectively, in one to one correspondence.

Title: Ultrashort pulse laser
Inventor: AOSHIMA SHINICHIRO
IPC: H01S3/131
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To make it possible to reduce in size an ultrashort pulse laser by highly repeating laser pulse, by disposing a laser medium between first and second optical components of phase dispersion compensator. SOLUTION: An exciting source supplies exciting energy to a laser medium 100. When natural radiation occurs in the medium 100 in this state, it is propagated through the optical path of a resonator while compensating the dispersion of the phase by a phase dispersion compensator 300 to generate inductive radiation. A mode synchronization is started by the Kerr lens effect of the medium 100. Thus, ultrashort pulse is obtained in repetition frequency f=218MHz by the mode-synchronized laser oscillation. The optical path distance between a prism 310 and a resonator mirror 510 is set to 5cm, and the optical path distance between the prism 320 and an output mirror 520 is set to 5cm, and resonator length L=56cm. Then, the ultrashort pulse is obtained at the frequency f=268Hz.

IPC: H05K3/00
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To reduce bubbles existing in a bonding layer formed between a heat radiation plate and a bonding board therefor through a simple structure. SOLUTION: The three layer structure board 10 for bonding a heat plate, where a copper plate 16 bonded to the lower surface of a copper plate 14 bonded to the upper surface of a ceramic base 12 is made thick, is mounted on a heat radiation plate 20 through a solder foil 22. Due to the difference of thermal stress being generated when the board 10 for bonding the heat plate and the heat radiation plate 20 are heated for bonding, the copper plate 14 elongates more than the copper plate 16 and the board 10 for bonding the heat plate is curved entirely to project downward to form a projecting curved surface. A bubble existing in a bonding layer formed between the board 10 for bonding the the heat radiation plate 20 is moved along the curved surface through buoyance thereof and discharged.  After the board 10 for bonding the heat radiation plate is cooled down slowly, the curved surface is reset to flat surface thus ending the bonding of the board 10 and the heat radiation plate 20.
