Inventor: KODERA YOSHIE
IPC: G11B7/24033
Filed: 1986-09-16
Abstract: PURPOSE:To provide high C/N and to increase an erasing speed by applying the intensity of the electric field different from the electric field at the time of storing information to both terminals of two electrodes while heating a memory film or applying heating thereto the restore the amount film to the initial stable state in erasing of the information. CONSTITUTION:The inverted electric field is applied to the memory film at the time of erasing to transfer the film at a high speed to the state of the other optical constant which is stable by the projection of low-output laser light and heating. More specifically, the DC voltage is applied to the electrodes 2, 4 and the condensed laser light 5 is projected onto the memory film 3. The memory film 3 is transferred easily to the other stable state to exhibit the different reflectivity by the opto-thermo energy of the laser light 5 in addition to the excitation of the energy level by the electric field impression thus the erasing of information is executed. The reproduction of the information is attained by scanning the laser light on the memory film at the level lower than the quantity of the laser light at the time of storing and erasing the information and viewing the presence or absence of a change in the reflectivity of the memory film 3 to reproduce the information. The storage of the information is executed by condensing and projecting the laser light 4 onto the memory film 3 having the reflectivity in the erasing state and changing the same to the reflectivity state which is the memory state to end the storage.

Title: Laser treatment device
Inventor: YOSHIHARA MASAYA
IPC: A61B18/20
Filed: 1989-08-25
Abstract: PURPOSE:To perform prompt and proper medical treatment of the affected part by means of laser irradiation by controlling both a detecting means for decting the affected part by inputting a detecting signal by means of ultrasonic waves and a detecting signal by means of fluorescence, and a medical treatment means by means of laser through a signal from the detecting means. CONSTITUTION:It is so contrived that fluorescence is introduced from a fluorescence observing device 9 via an optical-part changeover part 8 for obtaining fluorescence from the inner wall of the body cavity, and that the light signal is input into a control unit 16. When an excitation light is irradiated on the neighborhood of the affected part, fluorescence is emitted only from the cancer part being the affected part. In this condition, irradiation is carried out by means of the control unit 16. As the control methods, there are such methods - when either of the detecting signal from a ultrasonic wave observing device 13 or the detecting signal from the fluorescence observing device 9 is input, emission of radiation of laser is carried out through a laser device 12; or when both of the signals are input, emission of radiation of laser is carried out. Thus, after the affected part has been detected, prompt and proper irradiation of laser can be carried out for treating the affected part.

Title: Semiconductor device
Inventor: OKAMOTO TOMIO
IPC: H01L21/56
Filed: 1982-12-10
Abstract: PURPOSE:To efficiently radiate the heat generated at a semiconductor chip by providing a heat proof insulating material between a semiconductor chip and a substrate. CONSTITUTION:After forming a thick film 2, dams 4 and solder platings 3 on a ceramic substrate 1, polyimide resin 6 is dropped in the adequate amount of the area to which a semiconductor chip is to be bonded of the ceramic substrate 1. Succeedingly, a semiconductor chip 5 to be bonded to the substrate 1 is temporarily fixed to the specified area and is then placed in the furnace at a temperature of about 350 deg.C for the soldering. The products having completed the soldering are insufficient in hardening of resin and therefore they are subjected to the hardening for 2-3hr at 250-300 deg.C. The hardened polyimide resin has a thermal conductivity of 0.0007-0.0015cal/C.sec.cm which is almost equal to that of the epoxy resin used in general as the resin sealing material. When it is compared with that where air exists between semiconductor chip 5 and substrate 1, thermal transfer is carried out by the thermal conduction mechanism and heat radiation efficiency can be improved excellently.
