Title: Sample making of resin substrate
Inventor: INASATO SACHIKO
IPC: G01N1/06
Filed: 1989-10-06
Abstract: PURPOSE:To sharply obtain the shape of a groove, etc., on the surface of a resin substrate such as an optical disk, etc., by forming the cross-sectional shape of the resin substrate for observation after forming a notch on the back surface of the resin substrate and immersing the resin substrate in liquid nitrogen. CONSTITUTION:The optical disk substrate 1 is cut on a cutting line 2 to obtain a partial substrate 11 having a proper size. The slight groove of about 1-2mum is formed in an X direction on the substrate 1. Next, the groove 6 of about 1-2mm for dividing and cutting is formed on the divided and cut part on the back surface of the partial substrate 11 with a cutter for resin only. Then, the partial substrate 11 is cut on a broken line 9 in a size which is easy to be divided and cut to obtain a substrate slice 21 which is a part of the partial substrate 11. Then, the slice 21 is immersed in the liquid nitrogen 12 in a container 10 and divided and cut from the divided and cut part 6 with a radio plier in such a state. Since the resin is frozen, the slice 21 is instantaneously sharply divided and cut to obtain the sharp cross section and the sharp groove 5. By sticking the divided and cut slice 21 to a sample table and observing it with a scanning microscope, the shape and condition of the groove 5 is clearly obtained.

Abstract: PURPOSE:To obtain a radar wave-reflecting buoy having high reflecting function of radar-waves and enough durability and to provide its production method. CONSTITUTION:A radar wave-reflecting buoy 1 has a double layered construction consisting of a central nucleus 2 and an outer layer 3. The buoy 1 has a roping hole 4 at its center.

Two sheets 5 are adhered on the surface of the outer layer 3 by solvent welding. These sheets 5 are made of a synthetic resin of the same material as that of the outer layer 3 and tightly adhered to the outer layer 3 by solvent welding and are integrated with the buoy 1. After the synthetic resin is compounded with aluminum powder, it is molten to a sheet-shaped article to produce the sheets 5. Radar-waves are reflected by the sheets 5.

Title: Control apparatus for induction motor
Inventor: OMORI YOICHI
IPC: H02P21/00
Filed: 1996-09-12
Abstract: PROBLEM TO BE SOLVED: To suppress changes in the characteristic of a motor due to a tempera ture change by a method wherein the output of an error inner-product computing means is amplified and the primary resistance value of the motor used for a voltage-based magnetic-flux computing means is corrected. SOLUTION: An error inner-product computing unit 12 subtracts the current- based magnetic-flux vector ψ2i of the output of a current-based magnetic-flux computing unit 8 from the voltage-based magnetic-flux vector ψ2v of the output of a voltage-based magnetic-flux computing unit 6 so as to be filtered, and it computes the inner product of a current vector if so as to output an error Er. An error amplifier 13 proportional-integration-amplifies the error Er so as to output a proportional-integration element GR1. Then, a primary resistor 14 outputs, to the voltage-based magnetic-flux computing unit 6, a primary resistance setting value R1n .  Thereby, since the primary resistance R1 can be adjusted correctly and automatically, the control error of a speed or a torque is aliminated even when an actual primary resistance is changed due to a change in the temperature of a motor, and the stability of a system can be ensured.

Title: Gear controller for automatic transmission
Inventor: OKAHARA HIROBUMI
IPC: F16H59/44
Filed: 1989-10-11
Abstract: PURPOSE:To prevent the occurrence of severe transmission shock which may surprise drivers by forbidding the double reciprocal gear change of an auto- transmission which is equipped with main and auxiliary transmissions when current running conditions are within an automatic gear change area. CONSTITUTION:A detecting means (c) detects that current running conditions are within an automatic gear change area of which drivers cannot predict the occurrence of gear change, and when the rate of change of throttle opening detected by a detecting means (e) is smaller than a preset value a forbidding means (d) forbids the double reciprocal gear change of a main transmission (a) and an auxiliary transmission (b). In addition, a listing map for the double reciprocal gear change attempted to forbid is previously recorded in a gear change listing map setting means (f) to allow map retrieval of current change attitude. The detection of the double reciprocal gear change can be therefore promptly made to prevent the occurrence of malfunction. In this way, under driver unpredictable conditions the performance of the double reciprocal gear change of severe shock can be prevented.

IPC: H01L21/203
Filed: 1992-10-02
Abstract: PURPOSE:To provide the ion beam sputtering device which can deposit sputtered particles without generating gaps and can form a thin film having a uniform film thickness. CONSTITUTION:The shape of the ion collision surface 11a of a target 11 is formed as a parabolic surface. An ion source 13 is positioned in the focal position (a) of this parabolic surface. The ions I emitted from this ion source 13 collide against the ion collision surface 11a of the target 1 and release the sputtered particles S from the target 11. Since the ion source 13 is positioned at the focal position (a) of the ion collision surface 11a having the parabolic surface shape, the sputtered particles S are all released perpendicularly to the substrate 12 disposed to face the target 11 regardless of the emission direction of the ions from the ion source 13. These particles are deposited on this substrate 12 perpendicularly thereto. The thin film having the uniform thickness in which the gaps are not generated is formed on the substrate 12 by these sputtered particles.

Title: Manufacture of semiconductor device
Inventor: SUGII TOSHIHIRO
IPC: H01L21/203
Filed: 1989-10-13
Abstract: PURPOSE:To eliminate crystal defect and improve reliability by performing a process for forming a silicon film and a process for etching silicon at the same time in a same evaporation equipment. CONSTITUTION:When a silicon epitaxial layer 13a is grown on a substrate having lattice structure similar to the lattice arrangement of a silicon substrate 13 or silicon, a process for forming a silicon film and a process for etching silicon are performed at the same time in a same evaporation equipment 11. That is, the bonding force to a substratum of the atom which has attached on a part except lattice position is generally small as compared with the atom which has entered the lattice position. As a result, by suitably supplying etching gas during growth, only the atom which has attached on the part except lattice position can be etched. Thereby a silicon epitaxial layer wherein crystal detect is eliminated to the same degree as in the case of CVD method can be formed, and the reliability of manufactured device can be improved.
