Title: Apparatus for inspecting optical disk defect
Inventor: SHOMURA YOSHIAKI
IPC: G01N21/95
Filed: 1999-09-07
Abstract: PROBLEM TO BE SOLVED: To inspect pin holes of a multilayer multi-density disk in a simple constitution in a short time by radiating a laser light while rotating the optical disk, reflecting part of a quantity of light by a first reflecting film, reflecting most of the passing light by a second reflecting film, detecting a quantity of the reflected light and comparing the quantity with a reference level. SOLUTION: A laser light emitted from a laser light source 2 passes a deflecting beam splitter 202 through a collimate lens 203, is reflected by approximately 30% through a quarter-wave plate 201 by a reflecting film 9 of a disk 8 to be inspected and enters again the quarter-wave plate. Approximately 60-70% of a quantity of light passes the reflecting film 9, and approximately 80% of the quantity of light is reflected by a reflecting film 10, approximately 60-70% of which passes the reflecting film 9 and enters the quarter-wave plate 201 again. The laser light entering the quarter-wave plate 201 again is reflected by the deflecting beam splitter 202 and enters a photodetecting apparatus 204. An output voltage of the photodetecting apparatus 204 is compared with a reference level, thereby judging the presence of pin holes of the reflecting films 9 and 10.

Title: Resist coating apparatus
Inventor: KOMATSU ATSUSHI
IPC: H01L21/027
Filed: 1988-10-05
Abstract: PURPOSE:To prevent a dust particle from being produced when an evacuation quantity is lowered by a method wherein a quantity of particles at a resist coating part is monitored and the evacuation quantity is controlled to a prescribed value by using a forced evacuation apparatus. CONSTITUTION:When a wafer 2 sucked to a spin chuck 1 is coated with a resist, the resist produces dust particles at the inside of a resist coating cup 3 because it is spin-coated. The dust particles are counted by using a sensor 4; when the dust particles are produced in large quantities, a forced evacuation apparatus 5 is driven and a forced evacuation is executed through an evacuation pipe 6. Thereby, an evacuation quantity producing no dust particle can be controlled with reference to a quantity of the dust particles by using the forced evacuation apparatus; it is possible to prevent the dust particles from being produced when the evacuation quantity is lowered.

Title: Control system of speed of motor
Inventor: AIHARA TAKASHI
IPC: H02P21/00
Filed: 1985-11-13
Abstract: PURPOSE:To perform speed control having excellent response and high precision by learning the drift section of a speed detecting value by a tachometer generator system by using a rotor-position detector and compensating the speed detecting value on the basis of the result of the learning. CONSTITUTION:An output from a first detecting system consisting of a tachometer generator (TG) 10 and an A/D converter 11 is introduced to a comparator 14a, and a reaching to approximately rated speed is detected. Consequently, changeover switches 13a, 13c are turned ON and ones 13b, 13d are turned OFF, and an error at that time is memorized to a memory 12 as a drift section. Accordingly, the so-called drift learning period is formed. The drift section is memorized to the memory 12 after the learning, and introduced to an adder 7c through the switch 13c, thus compensating the output from the first detecting system by the introduction to the adder 7c of the drift section, then starting predetermined speed-alignment control.

Title: Optical disk reproduction device
Inventor: WADA YASUHIRO
IPC: G11B19/02
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To provide an optical disk reproduction device which can attain a high access speed and a low consumption of power. SOLUTION: An optical disk reproduction device is provided with an external storage 11 which has its capacity able to previously store the data on the inner circumference side of a disk 1, a means which previously stores the data on the inner circumference side on the disk 1 in the external storage 11, a means which judges whether a read instruction shows an inner or outer circumference address of the disk 1, and a means which reads the data out of the storage 11 when the read instruction shows an inner circumference address. In such a constitution, the moving range of an optical unit 3 is reduced and the change of the rotational frequency of a spindle motor 8 is also reduced. As a result, a high access speed and a low consumption of power can be attained with no use of the storage 11 of a large capacity.

Title: Manufacture of semiconductor device
Inventor: ARAI SHIGEMITSU
IPC: H01L21/3213
Filed: 1989-09-28
Abstract: PURPOSE:To enable uniform etching and improve yield even in the case of having circuit patterns with different etching region densities by providing a wafer with an etching pseudo pattern separate from a required etching pattern to keep the density of etching regions constant substantially, and then by etching them simultaneously. CONSTITUTION:The opening of an etching mask used to form through holes just under the ground electrode of a monolithic microwave integrated circuit(MMIC) for power supply use comprises through-hole pseudo patterns 12, 13 at a density of 40mum diameter and 90mum pitch centering around a through-hole pattern 11 in the through-hole planned region of a passive circuit in coincidence with the etching region density (40mu diameter and 90mum pitch) of an active zone (region I). It is preferable that the position of the pseudo patterns 12, 13 is so selected that they do not overlap MMIC patterns other than the ground electrode to prevent decreases in device yield. Employment of this method can reduce a past fluctuation in through-hole diameters of about 50% down to about 15%.

Title: Device for displaying loadage of tank
Inventor: TANAKA YOSHIFUMI
IPC: F17C13/02
Filed: 1986-10-24
Abstract: PURPOSE:To ensure the safe, precise and successive detection of the current loadage of a tank by detecting differential pressure between the upper surface and the lower surface of each tank chamber by means of a pair of pressure sensors so as to perform specific gravity compensation. CONSTITUTION:A switching valve 12 selects a tank chamber 4 whose loadage is to be detected. Thus, the detection values of pressure sensors 7, 8 are inputted into a differential pressure detecting means 11 so that differential pressure between the upper surface and the lower surface of the tank chamber 4 is detected. In this way, by detecting the differential pressure between the upper surface and the lower surface of the tank chamber 4, gauge pressure is detected out of the total pressure due to the dead load of combustible liquid loaded in the tank chamber 4. The differential pressure detected by the differential pressure detecting means 11 is converted into differential information P due to air pressure in the ratio of about 0.2-1.0kg/cm<2> by a converting means 13 so as to be inputted into a counting means 19. The counting means 19 divides the differential pressure information P by the specific gravity information gamma, thereby obtaining an air pressure signal.

Title: O2 sensor fixing structure for internal combustion engine having turbo-charger
Inventor: KOMATSU KATSUHIKO
IPC: F02B37/18
Filed: 1987-10-09
Abstract: PURPOSE:To prevent thermal degradation of an O2 sensor and to improve durability by combining a main path and a waist gate path in front of the output of an exhaust fitting and arranging an O2 sensor fixing section in front of the combined section of the main path. CONSTITUTION:A main path 8 and a waist gate path 9 are combined at a combining section 6a in front of the outlet of an exhaust fitting 6. Since high temperature exhaust gas is bypassed to the waist gate path 9 under high speed heavy load, quantity of exhaust gas colliding against an O2 sensor 1 is reduced to about 60% of conventional level. Exhaust gas in the main path 8 which performed turbine work through a turbine wheel 3 has lower temperature than that of exhaust gas in the waste gate path 9. Consequently, thermal degradation of a detecting element in a shield tube 1a of the O2 sensor 1 is suppressed, and durability of O2 sensor can be improved without sacrifice of function under low speed rotation.
