Title: Optical information processor
Inventor: TAKAMURA YASUHISA
IPC: G11B7/09
Filed: 1984-10-24
Abstract: PURPOSE:To obtain a light-weight and unexpensive optical information processor containing a simplified optical system, by providing optical detectors at the periphery of the light beam between the periphery of a condenser lens and the light source of the condenser lens and detecting the shift of the focus or a track. CONSTITUTION:When an optical disk 5 is set exactly at the focal position of a condenser lens 1, the reflected light sent from the disk 5 does not enter optical detectors 2 nor 4. If the disk 5 is set closer to the lens 1 than the focal point of the lens 1, said reflected light enters the detector 4. While the reflected light enters the detector 2 in case the disk 5 is not closer to the lens than the focal position of the lens 1. Thus the shift of the focus can be detected by obtaining the difference between outputs of both detectors 2 and 4. Then a light beam gets out of a track on the disk 5 owing to a fact that the detector 2 at the periphery of the lens 1 is divided into two parts toward the track on the disk 5. In such a case, a difference is produced between the diffracted light quantities produced from the tracks on the disk 5 which enter said two divided detectors respectively. Thus it is possible to detect a track shift by obtaining said difference of diffracted light quantity.

Title: Voltage detector
Inventor: WAKANA SHINICHI
IPC: G01R15/24
Filed: 1989-08-30
Abstract: PURPOSE:To miniaturize an apparatus detecting applied voltage and to enhance detection sensitivity by allowing two lights to be incident to an electro-optical crystal body changed in its refractive index by the applied voltage of an object to be detected and comparing a detected phase with a reference phase. CONSTITUTION:An electro-optical crystal body 14 is arranged in close vicinity to an LSI 10 and, when the voltage applied to the LSI 10 by an LSI driver 12 acts on the crystal body 14, the refractive index of the crystal body 14 is changed. Laser beams 28, 30 are synthesized to one beam by a polarized light beam splitter 32 and, thereafter, one beam is split into two beams by a beam splitter 34 and, when one beam is allowed to be incident to the crystal body 14, the phases of two measuring beams reciprocating in the crystal body 14 change and the signal of a photodetector 40 detecting reflected beams shows a detection phase having frequency of the frequency difference of two reflected beams. The signal of a photodetector 44 detecting the other beam shows a reference phase having frequency of the frequency difference of two incident beams. When the phase difference between the detected phase and the reference phase is calculated by a phase comparator 46, the applied voltage of the LSI 10 can be operated.

Title: Rotary drum device
Inventor: KAZAMA SABURO
IPC: G11B5/53
Filed: 1984-10-26
Abstract: PURPOSE:To obtain a rotary drum device having high performance with small thickness by using a support part for thrust loadof a rotary structure including a rotary drum or a member which has a displacement in the axial direction in response to the temperature characteristics of viscosity of a lubricant fluid for generation of fluid dynamic pressure of the load support part as a shaft member. CONSTITUTION:A fluid 100 is supplied mainly to a journal part from fluid sinks 9 and 11 at the upper end part of a housing. While the fluid is supplied mainly to a thrust receiving part from the fluid sinks 57 and 55 of a lower thrust receiving part. A thrust receiving member 5 uses a material that has a linear pressure supporting the thrust load of a rotary shaft 1 with fluid dynamic expansion coefficient, size and form accordant with the temperature characteristics of viscosity of the fluid 100. The viscosity of the fluid 100 varies according to the ambient temperature change. Then the fluid pressure value and the dynamic ligidity are changed to vary the floating degree of the shaft 1. This change of the floating degree is however absorbed by the expansion/contraction properties of the member 5 in the axial direction. Thus no planar fluctuation is produced to the height and position of a video head 25 as well as to the counter gaps of rotary transformers 7 and 8, etc. Then said fluctuation if produced can be suppressed down to a small degree.

Filed: 1990-08-24
Abstract: PURPOSE:To obtain a stabilized oxide film with a small interface level density by vacuum-sealing a compound semiconductor and an element with a higher vapor pressure and oxygen out of the components in a quartz ampule, and then thermally oxidizing. CONSTITUTION:A wafer cut out from InP single crystal is placed into a pBN- made vessel 1. This vessel is inserted into a quartz ampule 2 with the pBN-made vessel on which red phosphorus is mounted. After the ampule 2 is evacuated, oxygen gas is introduced. Then, the ampule 2 is sealed and heated in a heating furnace 10 where an oxide film is formed on the wafer 5. Under this construction, phosphorous is supplied to the front surface of the crystal from phosphorus vapor so as to prevent the shortage of phosphorous on the surface of the oxide film where uniform oxide film grows and moreover, the original surface of the substrate is covered with the oxide film. This construction makes it possible to obtain an oxide film having a small interface level density, minimize the mixture of impurities into the oxide film to be generated and hence enhance device characteristics.

CONSTITUTION:Lubricating oil, which is introduced from the oil inlet port 16 on a thrust plate 13 to the inlet port 6 of a crankshaft 1, is transferred through a communicating hole 7 outward in the radial direction with respect to a crankshaft 1 by centrifugal force caused by the rotation of the crankshaft 1, and supplied to an oil filler port 4, and then the oil is transmitted through said oil filler port 4 to each sliding part, such as an eccentric shaft 3 and a main bearing. In this case, the sludge, such as metal powder or the like, contained in the lubricating oil, is separated by centrifugal force and accumulated at the communication hole 7 between the inlet port 6 and a knock pin 9. Therefore, the abrasion in each sliding port, such as the eccentric shaft 3 or the like, can be deterred as much as possible.

CONSTITUTION:A curved line CV1 represents a shape into which the upper face of a work W is to be machined, while a curved line CV2 represents a shape into which the lower face is to be machined. A tool end position correcting amount (d) is an amount by which the tool is projected or retracted axially with respect to the tool from a point (ni'), where the point (ni') is a corrected position of the tool which has been offset in the direction of a normal of the curved face by the diameter of the tool from a point (nj) on the curved line CV2 of the lower face. When the correcting amount (d) is positive, the tool end is projected from the lower face of the work to realize excellent machining, while when (d) is a negative value, the tool end is retracted from the lower face so that a part having a step in its lower portion can be obtained. In such a manner, a curved face can be machined without any ruggedness on the lower face of a work, but with a desirable finish shape and good cutting properties.

Title: Optical switch
Inventor: NOMURA YOSHIKAZU
IPC: G02B26/08
Filed: 1992-07-31
Abstract: PURPOSE:To deal with slight deviations of the position of a movable element by designing an optical switch so that when the movable element is displaced sensor optical fibers are in alignment with each other. CONSTITUTION:Sensor optical fibers 40, 42... are accommodated in a fixed and movable element 10, 20, respectively, and at least one of the sensor optical fibers 40, 42... of the fixed element 10 and one of the fibers of the movable element 20 are aligned with each other before or after the displacement of the movable element 20. In this case, the sensor optical fiber 40 of the fixed element 10 and the sensor optical fiber 42 of the movable element 20 are aligned with each other before the displacement of the movable element 20. When a ray of light 46 is made to impinge on the sensor optical fiber 40 of the fixed element 20, it is transmitted to the sensor optical fiber 42. Further displacement of the movable element 20 prevents the ray of light 46 from being transmitted to the sensor optical fiber 42. When the movable element 20 is returned, the ray of light 46 is transmitted to the sensor optical fiber 42.
