Title: Separation of amino acid
Inventor: HAYASHIYA KEIZO
IPC: C07C239/00
Filed: 1988-03-09
Abstract: PURPOSE:To easily and economically separate amino acid by taking advantage of the permeability of amino acid through a fibroin membrane. CONSTITUTION:An amino acid solution is adjusted to pH5.5-13.0 and made to contact with a fibroin membrane to effect selective permeation of the amino acid through the fibroin membrane to the outside of the membrane. The fibroin of the fibroin membrane can be separated from cocoon produced by silkworm. As an alternative method, fibroin can be produced by drying an aqueous solution of fibroin and insolubilizing with ethanol or drying a mixture of an aqueous solution of fibroin with glycerol, etc., and insolubilizing the dried material. Amino acid is an essential nutrient and is useful as a synthetic intermediate for feeds and pharmaceuticals.

Abstract: PURPOSE:To prevent the film thickness reduction of an upper layer caused by a recess, by forming at least one of an isolation insulating film and a gate electrode leading-out wiring, below the interval part of a lower layer wiring intersecting an upper wiring. CONSTITUTION:Wirings 1, 2, 3, and interlayer insulating films 4, 5 for each layer are deposited on a semiconductor substrate 11.

IPC: G03G15/00
Filed: 1984-03-24
Abstract: PURPOSE:To prevent the occurrence of paper jamming, etc., by forming a projection or recessed part which extends in the conveyance direction of transfer paper at least a separation belt side part in the width direction of a conveyance guide plate which attracts the transfer paper electrostatically. CONSTITUTION:The conveyance guide plate 25 is installed under the exit side of a transfer area A and guides transfer paper S to a fixing device 10. This conveyance guide plate 25 is made of a conductive material and grounded to a main frame 28 through a resistance 27, and four ribs 26 are formed at the installation side of the separation belt in the conveyance direction. Namely, the transfer paper S normally holds charges at the transfer area A by the impression of an electric field from a transfer corona charger 9, so the paper after being separated is conveyed while attracted electrostatically on the conveyance guide plate 25. The ribs 26 provided to this guide plate 25 reduce the contacting area of the transfer paper S and weaken the electrostatic attractive force at this part.

Title: Light projection amount controller
Inventor: TSUNEKAWA TOKUICHI
IPC: G02B7/32
Filed: 1983-04-01
Abstract: PURPOSE:To detect distance by a light projection amount according to the condition of an object by controlling the light projection amount detecting charge amount stored in a charge storage section for storing a charge of a photoelectric conversion section during the projection and in a charge storage section for storing a charge of a conversion section during the fixed period in the non-projection. CONSTITUTION:With the emission of light from a light emitting element, reflected lights from an object form an image on a photoelectric conversion element. The conversion element is provided with photoelectric conversion sections AS and BS and the sum of reflected lights and ambient lights by projection is stored into charge storage sections AL and BL while ambient lights during a fixed period in the non-projection time are stored into charge storage sections AD and BD. Charges of the charge storage sections AL and AD and BL and BD are read out and the sum and difference of difference portions therebetween are detected as output VA+B and output VA-B respectively. The output VA+B is compared with a reference voltage by a resistance and a comparison output causes the duty from an oscillator to vary, for example, by 50, 25 or 12.5% to drive a light emitting element. The output VA-B drives by focusing through a control circuit. Thus, the control of the light projection can be done according to the condition of the object.

Next, a buffer layer 3 of n-type InGaP, an active layer 4 of undoped n-type InGaAsP, a clad layer 5 of p-type InP and a contact layer 6 of n-type InGaAsP are sequentially formed with the epitaxial growth method. After a rectangular mesa 2 is formed as expained above, a semiconductor layer including the active layer 4 is formed by the crystal growth method. In this case, the active layer of InGaAsP is disconnected from the upper and of rectangular mesa 2 at the flat part by the selective growth which is peculiar to the liquid phase epitaxial growth. Therefore, a diffused region 8 is partially formed so that a current can be applied only to the rectangular mesa 2 to form a current path.

Abstract: PURPOSE:To ensure alignment of parts which are long-sized and extended in one direction by fixing an alignment tray equipped with an alignment hole on a vibration generating device, and putting and fixing a storage tray on the alignment tray, the storage tray having a storage hole of diameter larger than that of the alignment hole. CONSTITUTION:A parts-aligning tray 30 which has an alignment hole 31 is fixed on the vibrator of a vibration generating device, and a parts-storing tray 60 which has a storage hole 61 of diameter larger than that of the alignment hole 51 of the alignment tray 30 is fixed on the tray 30, and a frame 70 is fixed on the tray 60, and screws 41 are casted into the frame 70. The screws 41 are stored in a storage hole 61 by vibrating the alignment device, and are next allowed to go into the alignment hole 31 so that they are aligned. In this case, those screws 41 which have their heads up can go into the alignment hole 31 via a through hole 31, while those which have their heads down can go into the storage hole 61 but cannot enter the alignment hole 31 and so they are removed from the hole 62 by vibration. It is thus made possible to surely align such screws that are long-sized and extended in one direction.

Title: Magnetizing method
Inventor: KITATSUME SEISHIRO
IPC: H01F13/00
Filed: 1986-03-18
Abstract: PURPOSE:To so magnetizing a stator as not to generate an irregularity in the rotation of a rotor by concentrically disposing a ringlike stator magnetic unit having a cutout on the peripheral surface and a ringlike yoke formed with a gap from the magnetic unit so that the cutout and the gap approach each other to be mounted in a magnetic field formed of an exciting coil. CONSTITUTION:When a current flows to an exciting coil 4, a magnetic flux is generated to flow to a ringlike stator magnetic unit and a ringlike yoke. Since the stator magnetic unit 4 has higher permeability than air, the magnetic flux which flows to the yoke mainly flows to the stator magnetic unit 7 for crosslinking the gap 6 at the open ends of the yoke 2. Accordingly, the magnetic flux generated by the coil flows to the stator magnetic unit and the yoke except the cutout 8 of the yoke 2, most of the magnetic flux flows to the stator magnetic unit in the cutout to magnetize the portions of the stator magnetic unit to be magnetized.
