IPC: G11B7/24024
Filed: 1989-07-07
Abstract: PURPOSE:To improve moisture resistance and long-term storage property by a simple constitution by sticking a first and a second substrate with an adhesive in which metal powder is dispersed. CONSTITUTION:The adhesive 3 is thermosetting resin or UV curing resin, into which one kind of metal powder 4 selected from Ti, Al, Mg, Bi, Ta, Si, W, Cl, Pd, etc., is almost homogeneously dispersed. The adhesive 3 is applied on the recording film of the substrate 1, to which a protective plate 5 is stuck to obtain the information medium disk 6. By using the adhesive 3 with metal powder 4 dispersed, oxygen contained in the water which intrudes into the adhesive reacts with the metal to produce oxides. Thereby, intrusion of oxygen into the recording film can be prevented. Thus, oxidation deterioration of the recording medium layer can be prevented and long-term storage property of the medium can be improved.

Title: Deflection scanning device
Inventor: NO YOSHITAKA
IPC: G02B26/10
Filed: 1996-06-17
Abstract: PROBLEM TO BE SOLVED: To suppress temperature rising inside a scanning device due to the heat generation of a drive motor part by forming a spatial part above a motor drive part for storing air heated up by the heat generation of the motor drive part. SOLUTION: A cover member 24 is provided with a shielding part 24b bulging over a polygon-mirror, and the inside of this shielding part 24b is used as a spatial part 24c for storing air heated up by rotation of the drive motor 15. Since the drive motor 15 rotates at a high speed for driving the polygon mirror 14, the air surrounding the drive motor 15 rises up to 40 to 50 deg.C, and the drive motor 15 stops running, the high temperature air will stays in the spatial part 24C, and the heat is radiated to the outer cool air from the shielding part 24b having a large osculation plane area with the outer air for an effective heat dissipation. Thus, it is possible to reduce the temperature rising of a scanning lens.

Title: Testing method for damp-proof property of semiconductor device
Inventor: YOSHIDA TOORU
IPC: G01M99/00
Filed: 1981-11-06
Abstract: PURPOSE:To make it possible to evaluate in a short time the damp-proof property by leaving a semiconductor device under high temperature and high humidity after permeating into the semiconductor device a solvent that corrodes metalic materials and developing in a short time disconnection due to corrosion in a metallic wiring material. CONSTITUTION:A semiconductor device 1 to be tested in which aluminum wiring is installed is thrown in a high pressure vessel 2, and in this vessel brine 3 with salt of 3-23wt% is added. The pressure in the high-pressure vessel 2 is made at 5atm by a high-pressure air cylinder. In this state the vessel 2 is left for 16hr. Then the brine permeats into the device 1. Next, the device 1 is put in a high- temperature, high-humidify tank 7 of 85 deg.C and 100% RH, and left in it. Then the salt water 3 further permeates into the device 1 to reach eventually the surface of a semiconductor chip. If the chip has a defect that an aluminum wiring is exposed on its surface, the wire will be cut by corrosion in a short time. It is, therefore, possible to evaluate in a short time the damp-proof property and in this way breakage can be avoided because the high temperature condition is not required as in the PCT method.

Filed: 1988-07-18
Abstract: PURPOSE: To improve the comparison precision by using nearly the same transistors(TR) as switch TRs which operate in the 1st period and 2nd period of a capacity-coupled input differential amplifier. CONSTITUTION: In the 1st period, switches 10, 12, 14, and 16 are closed. At this time, the voltage of a capacitor 9 is the difference between an analog voltage Ue and the inverted input terminal voltage of the differential amplifier 8. Further, the voltage of a capacitor 13 is the difference between a reference voltage Uref and the uninverted input terminal voltage of the differential amplifier 8. In the 2nd period, switches 11 and 15 are closed and the switches 10, 12, 14, and 16 are opened. At this time, the output voltage of a digital-analog converter is added to the capacitor 9 and the reference voltage Uref is added to the capacitor 13. Here, when the switches are composed of the same TRs, charges having the same size and polarity are added to the capacitors 9 and 13. Those voltages in in-phase mode are excluded by the differential amplifier 8.
