Inventor: YAGYU SHINGO
IPC: G11B5/31
Filed: 1995-06-21
Abstract: PURPOSE: To drastically decrease compressive stresses and to eliminate defects, such as peeling of insulating films and crack of substrates, by forming a thin-film magnetic head by laminating nonmagnetic inorg. insulating material thin films for embedding coils essentially consisting of SiO2 and nonmagnetic inorg. insulating material thin films exclusive of these thin films.

Title: Velocity measuring instrument using laser beam
Inventor: KANO HAJIME
IPC: G01S17/58
Filed: 1985-08-12
Abstract: PURPOSE:To measure the velocity of the body to be measured correctly by adjusting the positions of the optical system and the body to be measured based on the reflecting light of two laser beams irradiated on the measuring face in the velocity measuring instrument using laser beam by dual beam mode. CONSTITUTION:A laser beam is divided into two parallel beams by a beam splitter 2 and irradiated on the body 6 to be measured through a condensing lens 3. In this case, a beam 20 is reflected by the body 6 to be measured and inputted into a photoelectric transducer 12 by being reflected with a half-mirror 5 passing through the condensing lens 3. A beam 21 is reflected by the body 6 to be measured similarly as well and inputted to a photoelectric transducer 11. The position of the body 6 to be measured is then adjusted so as to make the output difference minimum by inputting the output of two photoelectric transducers 11, 12 to a differential convertor 13. After this adjustment, the reflecting beam from the body 6 to be measured is received to a photoelectric transducer 9 via reflection lens 7, condensing lens 8 in the dual beam mode and then the velocity is measured by a signal processor 10. The velocity of the body to be measured can therefore be measured with high accuracy due to the position of the body to be measured being adjusted.

Title: Exposure device for shadow mask
Inventor: ISHIKAWA SATOSHI
IPC: H01J9/14
Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To provide an exposure device for a shadow mask capable of making a printing board reliably adhere to a thin metal plate and having enhanced productivity and stable quality. SOLUTION: Holding frames 16, 17 hold and fix each printing board 12, 13. A hollow packing 21 is connected to a compressor 22c to heighten its inner pressure, and is kept in a solid state. The holding frames 16, 17 are evacuated by operating a vacuum mechanism 18. Since the packing 21 is in a solid state, each printing board 12, 13 is sucked from its center part to a thin metal plate 11 by a vacuum pressure. The inner pressure of the packing 21 is then lowered to soften the packing 21, and if a vacuum adhering work is continued by keeping the air in the outer rim part of each printing board 12, 13 easily released, it reliably adheres to the thin metal plate 11 without having stagnant air in its center part. Under this condition, it is exposed and baked with a super high mercury lamp 14.

Title: Pressure alleviating device for delivery port of screw type compressor
Inventor: FUJIWARA AKINORI
IPC: F04C18/16
Filed: 1986-07-29
Abstract: PURPOSE:To prevent the occurrence of abnormally high pressure near the delivery port of a bearing head casing by forming a recess adjacent to said port and on a delivery end wherein fluid containment is formed, for storing a contained fluid temporarily. CONSTITUTION:In the delivery end surface of a bearing head casing 1, a blind hole 27 is formed at a part adjacent to a delivery port 6 and containing a fluid for storing temporarily the fluid in the final stage of delivery stroke. According to the aforesaid constitution, the fluid tending to give abnormally high pressure due to containment in the final stage of the delivery stroke escapes into the blind hole 27 and is stored temporarily therein, thereby enabling the alleviation of the abnormally high pressure in the final stage of the delivery stroke. As a result, it becomes possible to prevent the occurrence of erosion near the delivery port 6 and the vibration and noise of a compressor.

Title: Semiconductor wafer
Inventor: MORIUCHI NOBORU
IPC: H01L21/02
Filed: 1988-07-18

Title: Field-effect transistor
Inventor: TSUBAKI KOTARO
IPC: H01L29/812
Filed: 1984-08-27
Abstract: PURPOSE:To obtain a FET having large mobility and electrical characteristics stable against light irradiation by burying fixed charges having the same polarity as the storage charges of a first semiconductor layer to the interface between the first semiconductor layer and a second semiconductor layer in approximately the same number as the storage charges. CONSTITUTION:Negative charges are buried to the interface 18 between a GaAs substrate 11 and an N-AlxGa1-xAs layer 12. Repulsive force works among electrons stored in the substrate 11 and negative fixed charges existing on the interface 18, and electrons are separated from the interface 18. Consequently, the effect of coulomb interaction by donors in the layer 12 is reduced in stored electrons. Electrons do not travel in the strain sections of atomic arrangement due to the discordance of lattice constants existing on the interface 18, thus increasing mobility. When the number of negative fixed charges buried is made approximately the same extent as the number of electrons stored, mobility is maximized.

Filed: 1999-06-25
Abstract: PROBLEM TO BE SOLVED: To improve the service life of a stirring nozzle by blowing gas for stirring into molten metal produced in a melt-reduction smelting from the side part near the furnace bottom part of the molten metal. SOLUTION: Plural pieces of furnace bottom nozzles 11 are arranged at the bottom part of a smelting furnace 1, and plural pieces of side nozzles 12 are arranged at the side wall part near the bottom part, and the gas 13 for stirring is blown into the molten metal 2 from these nozzles to stir the molten metal 2 and molten slag 3 under a specific condition.

Filed: 1988-07-20
Abstract: PURPOSE:To improve the feeling of acceleration and acceleration performance by providing a means to slide a clutch when a signal from a part to calculate the ratio of a target speed change ratio to an actual speed change ratio is more than a set value, and connect the clutch directly when it is less than a set value.

Blowup speed of an engine and a transition speed of a speed change ratio to the low side are thus increased, so acceleration performance is improved, and that the feeling of acceleration can be obtained corresponding to the acceleration work of the driver.
