IPC: H01L29/80
Filed: 1986-06-12
Abstract: PURPOSE:To inhibit deterioration of yield due to the dummy gate inversion process, by covering the surface of a dummy gate formed region with a predetermined insulation film before applying resist and removing the resist completely by etching. CONSTITUTION:An active layer 12 and an ohmic layer 14 of an FET are formed on a semi-insulating substrate 11 by means of the selective ion implantation using a dummy gate 13 and photolithography technique. The structure is heat treated and source and drain electrodes 15 are formed. A CVD-SiO2 film 16 is deposited over the whole surface of the substratre. Resist 17 is applied on the film 16 by means of the spin-on process and baked. Then, the resist 17 is etched back by the CF4 RIE so that the resist 17 ands the film 16 are completely removed. Thereafter, the gate 13 is removed by the CF4 plasma etching process in which the aspect ratio of CVD-SiO2/PVCD-SiN is 20, so that gate electrode window 18 is formed. A layer of Ti/Pt/Au 19 of 1000/500/1000 Angstrom is vapor deposited over the whole surface. A layer 21 is formed over the gate by means of the photolithography technique using resist 20 as a mask. Finally, a gate electrode 22 is formed.

In addition, the layer 3'' fuses and acquires an adhesion strength, centering around the contact portion (protruded portion) with the recording medium. Namely, an adhesion strength is created by the layer 3'' to the recording medium 4, and at the same time, the layer 3' acquires an increased strength within the dot portion by the energy applied, resulting in accomplishment of the transfering of the ink layer 3 onto the recording medium with no surface smoothness.

Title: Magneto-optical recorder
Inventor: ISHII KAZUNORI
IPC: G11B11/10
Filed: 1992-05-01
Abstract: PURPOSE:To prevent the serious damage to be incurred by an impact on a recording medium by providing a means for unloading an impact detecting element and head on a magnetic head side. CONSTITUTION:The impact detecting element 5, such as AE sensor, on a slider 2b detects the impact generated by dust, etc., between a magnetic field generating element 2 and a disk surface, changes this impact to an electric signal and supplies the signal to an amplifier circuit 7. The detection signal amplified in this amplifier circuit 7 is compared to a preset value in a comparator circuit 8 and is counted up by a counter circuit 9 at every time when the intensity of the impact exceeds over a set value. An alarm signal is emitted to a control circuit 10 when the count value exceeds over regulated value. A signal is then emitted from the control circuit 10 to a solenoid mechanism 6 and the magnetic head 2a is unloaded. The serious damage of the recording medium is therefore averted and the normal recording is maintained.

Title: Production of rubber material, and rubber material produced thereby
Inventor: ICHIBA YASUYOSHI
IPC: C08J11/04
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To provide a process for producing a rubber material whereby waste rubbers such as used tires can be recycled and a rubber material excellent in mechanical properties can be produced at a low cost. SOLUTION: A primary raw rubber material 1 comprising a vulcanized rubber powder is mixed with a hot-melt agent 2' at a temp. sufficiently higher than the m.p. of the agent. The resultant mixture is cooled is further mixed with a secondary raw rubber material 4 comprising a vulcanized or unvulcanized rubber together with a vulcanizing agent 5 and a vulcanization aid 6, and is vulcanized and molded at a temp. of 120-210 deg.C under a pressure of 30-80 kgf/cm<2> for 15-40 min, giving the objective rubber material.  Since the primary raw material 1 is brought into a good contact with and hence is coated with the hot-melt agent 2 and the secondary raw material 4 is brought into a good contact with the vulcanizing agent 5 and the vulcanization aid 6, vulcanization and adhesion proceed simultaneously and sufficiently during the reaction, thus giving a low-odor rubber material excellent in mechanical properties and solvent resistance by a two-stage operation.

Title: Hologram recording and reproducing device
Inventor: SUGANUMA HIROSHI
IPC: G03H1/10
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To remove unnecessary interference noises without making signal processing difficult by recording the interference fringes generated by the interference of the object light and reference light past part of an object to be recorded. SOLUTION: The exit light of a laser beam source 1 of a narrow line width is separated to the object light and the reference light by a beam splitter 2 for the purpose of improving Bragg angle selectivity. The reference light is reflected by a first mirror 3 and the progression direction thereof is controlled by a reference light deflecting means 4, by which the reference light is made incident via a second mirror 5 on a hologram recording medium 6. The incident angle thereon is changed by each of the respective holograms, by which angle multiplex recording to the one hologram recording medium 6 is made possible.  On the other hand, the object light is subjected to intensity modulation by an object light intensity modulating means 7 and is then changed in its progression direction by an object light deflecting means 8 to form a light spot to a spatial modulating means 9, by which this means is scanned. This light is made incident on the recording medium 6 and is recorded as the interference fringes interfered with the reference light. The recording of the hologram is thus executed at the respective points on the spatial modulating means 9, by which the unnecessary interference noises may be decreased.

Title: Exposure controller
Inventor: SHIMIZU HIDEJI
IPC: G03B7/08
Filed: 1994-06-20
Abstract: PURPOSE:To obtain an exposure controller capable of controlling an exposure to an adequate exposure regardless of photographing conditions by determining the exposure according to illuminance of a set limiter value or below. CONSTITUTION:The limiter value in the peripheral part of a picked up image is preset in the limiter setting circuit of a limiter value setting means 2 of this exposure controller 10. The weight of the upper part of the picked up image is preset in the weight level setting circuit of an exposure calculating section 5 of an exposure control means 3. The influence of the back light in the upper part is suppressed by applying the weight of 31 to the upper part where the influence is large at the time of the back light in such a manner and in addition, the illuminance in the peripheral part of the prescribed value or above is suppressed and the back light state is sufficiently suppressed by detecting the illuminance in the peripheral part of the properly preset limiter value or below. The illuminance is detected without conversion in the peripheral part and the central part as well except the conversion by the weighting of the upper part even in an over-follow light state and, therefore, the exposure is correctly controlled and the over-follow light state is sufficiently suppressed.

Title: Electric power amplifier
Inventor: HAYASHI TAKAAKI
IPC: H03F3/68
Filed: 1988-06-03
Abstract: PURPOSE:To detect whether the action of an electric power amplifier is normal or abnormal and to discriminate a fault amplification system when the amplifier is abnormal by setting plural comparison detection levels to values corresponding to the outputs of respective amplifier systems when they are abnormal. CONSTITUTION:Action is supervised by inputting monitor signals from a detector 8 to comparators 9-11 whose detection levels respectively differ. In the setting of respective detection levels of the comparators 9-11, the detection level of the comparator 9 corresponds to a state where one of amplification elements 3 has a fault, the detection level of the comparator 10 to the state where one of amplification elements 2 has the fault, and the detection level of the comparator 11 to the state where an amplification element 1 has the fault. The amplitude of the monitor signals are always compared by the comparators 9-11. The fault part of the amplification system in three levels is partitioned by the difference of the comparator which detects the fault when the amplification element has the fault.
