Title: Optical head
Inventor: GOTO YOSHIKAZU
IPC: G11B7/12
Filed: 1990-01-10
Abstract: PURPOSE:To improve a recording and reproducing characteristic by constituting a mobile carriage with a light translucent member, and using it also as a recording and a reproducing means. CONSTITUTION:A light beam from a fixed optical part 3 passes through the transfer carriage 11 of a light translucent material, and is converged by an objective lens 19. Then, an information track on an optical disk 1 is irradiated with the beam. The reflected light of the disk 1 is made incident on a photodetector 10 through a detecting lens 9 by a 1/4lambda wavelength plate 8 and a polarized beam splitter 7 in the optical part 3, and the signal for the read-out of an information signal, focus control and tracking control is outputted. A driving current is made flow from a focus coil 21 and a tracking coil 22 by this signal, and an objective lens holder 20 is moved by the action of this current and the magnetic flux of a magnetic circuit 24 for the objective lens to make the lens 19 follow the prescribed track of the disk 1. Thus, positional relation between the reflecting mirror part 11a and the V-groove part 11b of the carriage 11 is determined univocally, and since the setting variance of an optical axis or the occurrence of parasitic oscillation can be suppressed, the recording and reproducing characteristic of an optical head can be improved.

Title: Method and apparatus for controlling electric motor incorporating friction clutch
Inventor: KAWADA FUMIAKI
IPC: H02P29/00
Filed: 1993-01-12
Abstract: PURPOSE:To prevent a friction clutch on an electric motor from burning or wearing, and adverse effects of chips resulting from abrasion on bearings, etc., by cutting or reducing power supply to the motor when it rotates slower or is locked due to an excessive external load while monitoring the rpm of the output shaft. CONSTITUTION:To start a motor (M), an ON-OFF signal generator 47 issues an ON signal, and on receiving the ON signal a timer 44 outputs an ON signal to a power control circuit 45, which then feeds electric power from a power source 46 to the motor (M). Thus, the motor (M) starts rotating. When an excessive load is applied to the motor (M), a built-in clutch mechanism will slip. When the motor rpm detected by a rotation detector 41 lowers below the rpm indicated by a reference speed indicator 42, a speed comparator 43 will issue a signal to timer 44, which will output an OFF signal to the power control circuit 45 after a pre-set time passes. On receiving the OFF signal, the power control circuit cuts the power supply from the power source 46 to the motor (M).

Filed: 1998-01-12
Abstract: PROBLEM TO BE SOLVED: To secure a uniform state of vegetation by forming a basic foundation for plant growth through a carbonized layer at the basic layer for a slope face, thereby absorbing the cause of plant growth obstruction, preventing the runoff of fertilizer components and improving trainability. SOLUTION: A carbonized layer 2 constituted with the carbide of lumber by carbonization or activated carbonization is formed to a predetermined thickness, on which a plant growth basic layer 3 constituted with soil containing micro-organism and fertilizer components good for the growth of plants is formed to the predetermined thickness. If the basic layer 1 of face of slope is soil with a strong acidity, a pH adjuster is added to the carbide layer for preventing the influence to the plant growth basic layer. Also, carbide is mixed to the basic layer 3 for plant growth for activating the activity of micro-organism, thereby accelerating the germinating rate of the plants and preventing the runoff of fertilizer components.  Thus, the causes for plant growth obstruction existing in the basic layer 1 of slope face are absorbed by the carbide layer 2, runoff of fertilizer components are prevented and the drainability is improved and a uniform state of vegetation can be secured.

Title: Adhesion process for synthetic resin sheet to mold made of al alloy
Inventor: SATAKE SHINJI
IPC: B29L9/00
Filed: 1986-01-11
Abstract: PURPOSE:To obtain high-grade adhesive strength by sticking the print sheet made of synthetic resin onto the coating film of the profile made of Al alloy having thermosetting film of acryl melamine on anode oxide layer with the solvent type adhesive of specified polyurethane base or urethane rubber base. CONSTITUTION:The print sheet made of synthetic resin is stuck onto the coating film of the profile made of Al alloy having the thermosetting film of acryl melamine base on anode oxide layer without removing said coating film by the solvent type adhesive of polyurethane base or urethane rubber base in which the solvent concentration of methyl acetate or methylene chloride is adjusted into 10wt% or more and 50wt% or less. When said solvent concentration exceeds 50wt%, it shows good result in Erichsen test and cheekers test, but the print sheet is easily separated for the tensile load at room temperature and under heating. The Al profile expected to be used at the state where it receives direct sun light, has some practical questions. On the other hand, when said solvent concentration is 10wt% or less, the tack as an adhesive is decreased. It is undesinable because the concentration adjustment of the solvent becomes industrially difficult.

Abstract: PURPOSE:To prevent generation of defocusing caused by foreign matter on the rear of a wafer in exposure by classifying wafers into those where foreign matter is above allowance and those where it is below allowance before exposure, and conveying the wafers where foreign matter is below allowance to a chuck. CONSTITUTION:A wafer 12 is conveyed from a wafer cassette 11 to a foreign matter detector 15 along a conveyance path 14. Next, foreign matter B on the rear of a wafer 12 is detected by scattered light by means of the foreign matter detector 15.

And in case that the foreign matter B (scattered light) is above allowance, the wafer 12 is conveyed onto a chuck 13 along a conveyance path 14. Hereafter, the wafer 12 is conveyed as an already exposed wafer to a wafer cassette 16 along a conveyance path 18. Hereby, the wafer 12 is never conveyed to the chuck 13 in the condition that the foreign matter B adheres, above the allowance, and generation of defocusing by the deviation from image face (focus face) of a projecting optical system can be prevented in case of transcribing a mask image.

Patent JP-H02184592-A (JP)
Title: Method for crystal growth
Inventor: NAKAJIMA KAZUO
IPC: C30B15/00
Filed: 1989-01-11
Abstract: PURPOSE:To obtain bulk mixed crystal of few defects with high composition uniformity by rotating a substrate-supporting part holding seed crystals at positions off the revolving axis in such a state that said seed crystals are immersed in a growing solution. CONSTITUTION:Seed crystals 11-16 are fixed to a substrate-supporting part 2 so that the crystal growth planes for said seed crystals fall at positions off the revolving axis 33. Thus, the relative flow speed of a growing solution to said seed crystals will increase when a revolving bar 3 is revolved around the revolving axis 33, leading to inhibition of dendrite growth with fresh solute elements replenished successively onto the crystal growth plane. This effect will be greater as the crystal growth plane for said seed crystals is made further apart from the revolving axis. Although such a greater distance necessitates a larger crucible, the above-mentioned relative speed can be increased using a small crucible with the lateral extension of the locations of the seed crystals suppressed to a smaller extent, therefore said crystal growth plane is tilted from the horizontal plane or made vertical.
