Title: Manufacture of line for magnetic disk cartridge
Inventor: MIZUTA AKIRA
IPC: G11B23/033
Filed: 1995-01-31
Abstract: PURPOSE: To obtain a liner by which the inner face of a cassette shell on which the liner has been pasted can be brought into contact with a magnetic disk uniformly and with high accuracy by a method wherein the whole face of the liner pasted on the inner face of the cassette shell for a magnetic disk cartridge is made fuzzy. CONSTITUTION: The liner 8 which has been stamped from a thick nonwoven cloth is pasted on the inner face 7a facing a magnetic disk of a cassette shell 7 for magnetic disk cartridge. After that, while a brush roll 9 which is provided with a brush 9a on the circumference is being turned from its upper part, the inner face is brought into contact with the surface of the liner 8, and fuzzy parts are formed on the surface. Thereby, since the fuzzy parts formed on the surface after the liner 8 has been pasted on the inner face 7a of the cassette shell 7, it is not required to pay attention so as not to lay the fuzzy parts after the fuzzy parts have been formed.

Title: Production of metallic copper fine powder
Inventor: KAWASUMI YOSHIO
IPC: B22F9/20
Filed: 1985-01-30
Abstract: PURPOSE:To obtain metallic copper fine powder having a controlled particle shape or particle size by adding either inexpensive cuprous oxide particles for a ship bottom paint or an acid while expending more than a fixed time so as to obtain the strong acidity less than a prescribed pH value of the resultant slurry and by allowing to react both with each other. CONSTITUTION:Cuprous oxide particles for a ship bottom paint which are inexpensive, chemically stable and readily available in large quantities and an acid such as nitric acid, phosphoric acid, acetic acid, etc. particularly sulfuric acid are mixed and the homogenizing of above-mentioned cuprous oxide particle slurry and the acid is promoted by stirring, etc. In this case, it is necessary that the quantity of acid to be added or mixed is added while expanding >=15min so as to obtain <=2.5pH value of the resultant slurry. The slurry concentration of the cuprous oxide particles is 1-400g/l, preferably 100-200g/l, and when the acid is sulfuric acid, the preferable acid concentration is 100-500g/l. As a result, the cuprous oxide fine powders having a controlled particle size and a globular form without containing a rod-like or needle-like powders are obtained without requiring processes such as classification, screening, mixing, etc.

Title: Semiconductor light emitting element
Inventor: MARUO YASUHIRO
IPC: H01L33/36
Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor light emitting element in which high luminance can be attained through surface roughening while enhancing the reliability by arranging the peripheral part of a first electrode tightly on a rough surface region. SOLUTION: Since a part of the upper surface 13a of a substrate 13 not covered by an electrode 14, i.e., a light take-out face, is a rough surface region 18, total reflection of a light emitted upward from a PN junction 16 is suppressed and the light can be taken out well to the outside of an element thus realizing high luminance. Since the anode electrode 14 is formed across a mirror surface region 17 and the rough surface region 18 and the peripheral part of the electrode 14 is coupled tightly with a part of the rough surface region 18, side etching can be confined, if any, within the peripheral part extremely close to the electrode 14. Since side etching can be prevented from spreading to the mirror surface region 17 side, the electrode 14 is bonded rigidly to the substrate 13 resulting in the enhancement of reliability of a light emitting element.

CONSTITUTION:An opening part end face of a package body 12 is stuck to a light-transmitting sealing glass 15 covering the whole surface of the upper face of the package body 12 by means of an adhesive 17. Further, the external face angular parts of the package main body 12 of the sealing glass 15 are of deprived corners so as not to hinder fitting of a fiber scope or the like into a mirror tube part in order to form a tapered or rounded face. Then, the peripheral part of the inner surface of the sealing glass 15 is not subjected to chamfering so as to form a right-angled part 15B making 90 deg. of the inner face and the peripheral face. Thereby, the device as a whole can be small-sized.

Title: Vehicle slip control device
Inventor: YAMASHITA TETSUHIRO
IPC: B60W10/06
Filed: 1992-01-30
Abstract: PURPOSE:To provide a slip control device of a vehicle which is capable of preventing the feeling of stall of a driver when the vehicle is started or accelerated by enabling the specified traction control by limiting the engine output. CONSTITUTION:When the vehicle acceleration (A) is not less than the set value AT in the step S4, the throttle gain GV is corrected to be increased in the step S6 if the throttle gain GV is positive in the step S5, while the absolute value of the throttle gain GV is corrected to be reduced in the step S7 if the throttle gain GV is negative (i.e., the control gain where the slip ratio tends to be reduced is corrected to be reduced.), regulating the limit to the engine output. This allows the slip regulation in the high mu road where the vehicle acceleration can be larger, and the feeling of stall due to the limit to the engine output can be prevented, while the slip regulation is not achieved in the low muroad where the vehicle acceleration can not be larger, preventing the generation of the excessive slip where the gripping power of the driving wheels can not be recovered.

Title: Buffer amplifier
Inventor: YAMAGUCHI TSUGIO
IPC: H03F3/45
Filed: 1986-01-27
Abstract: PURPOSE:To eliminate an offset voltage without increasing the current consumption and the occupied area by reducing an output current to 1/N to detect it and generating a base current on a basis of this detection current and multiplying the base current by N to feed back it. CONSTITUTION:A 1/N current of an output current IO of a constant current source 9 is generated by a constant current source 11, and a base current IB/N of 1/N of a base current IB of a transistor TR 8 is obtained as the base current of a TR 12. This current IB/N is multiplied by N in a current mirror circuit consisting of TRs 13 and 14, and the multiplied current is fed back to the collector of a TR 3. Thus, the unbalance between collector currents of TRs 2 and 3 due to the base current IB of the TR 8 is compensated to eliminate the offset voltage. Since an offset eliminating circuit of a TR 14 is not connected to an output terminal 10 from the constant current source 11, the dynamic range of the output voltage is not affected.

CONSTITUTION:If the light distributing characteristics of an illuminating lamp in such a way that the quantity of emitted light is large in both end parts in the longitudinal direction and is small in the central part in the longitudinal direction by taking  the cosine law, etc. of a lens 1 into consideration, the width of slit-like openings may  be constant in the longitudinal direction but if the quantity of the light emitted by the  illuminating lamp is uniform in the longitudinal direction, the width of the openings in  light shielding members 4, 5 is so determined as to be small in the central part in the  longitudinal direction and increases gradually the nearer the two end parts in order to  make the exposure in the longitudinal direction in the slit exposure parts uniform.  Then, even if a light shielding member 6 is not moved, the quantity of shielding the  exposure luminous flux changes continuously owing to the directional change of the  exposure luminous flux in the stage of slit exposure, so that the quantity of shielding is zero at points A', B' and is larger the nearer the central part of A', B'; therefore, the  exposure on the photoreceptor is made uniform.
