Title: Magnetic recorder
Inventor: ARIGA TOMOE
IPC: G11B21/12
Filed: 1986-09-30
Abstract: PURPOSE:To prevent the degradation of a turning means by damping the turning of the second carriage by the turning means consisting of a very thin plate- shaped metallic part with a prescribed gap between the turning means and the second carriage. CONSTITUTION:The second carriage 4 consists of a plate-shaped metallic material which is very thin to have 0.05-0.3mm thickness and has a flexibility. The turning means consisting of the flexibility of suspensions 4a and 4b has a damper 11, which has an elasticity to stabilize turning, between a suspension holder 6 and suspensions 4a and 4b. The damper 11 is larger than the gap between the suspension holder 6 and suspensions 4a and 4b in the single body state; and when the damper 11 is set, it is compressed to cause a compressive reaction force. Thus, the damper 11 controls the second carriage 4 so that it is not turned beyond a required extent of turning even if oscillation, shock, or the like is applied at the time of turning the second carriage 4, and the degradation of the turning means is prevented.

Title: Flexible magnetic disk
Inventor: KAZAMA KATSUYA
IPC: G11B19/20
Filed: 1992-07-17
Abstract: PURPOSE:To prevent the generation of vibrations and the eccentrically of tracks even if a disk is rotated at a high speed by providing the center of the flexible magnetic disk with a central hole and a driving hole and providing the side nearly opposite from the driving hole with plural balance holes. CONSTITUTION:The flexible magnetic disk mounted with a disk for disk driving, i.e. a hub 2 having the central hole 4 and the driving hole 5 is provided at the center of the flexible magnetic disk 1. The hub 2 of this disk 1 is provided with the balance holes 9 or notches on the side nearly opposite from the driving hole 5 in addition to the central hole 4 and the driving hole 5. The balance holes 9 are formed to such a size at which a driving pin 8 of a spindle motor does not enter the holes. While there is the possibility of a degradation in the magnetic characteristics of the hub by the increase of the holes in the hub 2, the influence thereof is extremely slight and negligible. Then, the generation of the vibrations and the eccentricity of the data tracks are suppressed even if the disk is rotated at a high speed. The flexible magnetic disk which is high in magnetic recording is thus obtd.

Title: Headlight for vehicle
Inventor: TAKANISHI HIROYOSHI
IPC: H01J61/34
Filed: 1985-10-18
Abstract: PURPOSE:To improve the heating efficiency of a light emission tube by arranging a preheater below the light emission tube while to protect a vehicle on the opposite lane from glare by positioning the center of light emission at the same position or in front of the focus position of a reflection mirror. CONSTITUTION:Since it is lighted while bringing an outer tube 1 into horizontal and a preheater 3 is arranged below a light emission tube 2, the light emission tube 2 is subjected to the radiation heat and the convection heat from the preheater 3 thus to improve the heating efficiency. If the center of light emission LO of the light emission tube 2 is in front of the focus point F, the downward light C will increase to reduce the upward light A, B considerably thus to never cause glare for a vehicle on the opposite lane. Consequently, when positioning the center of light emission LO at same position or in front of the focus position F, it will never cause glare for a vehicle on the opposite lane even if the preheater 3 is arranged at the underside of the light emission tube 2.

Filed: 1992-09-01
Abstract: PURPOSE:To form a high-concentration layer, for non-alloy ohmic contact use, wherein impurities are not accumulated at an interface and a surface morphology is good by a method wherein an InGaAs layer is formed while a substrate temperature is being lowered as an indium composition is increased. CONSTITUTION:A gradient-composition InGaAs layer in which an indium composition is changed from 0 to 0.5 is formed on a substrate by increasing substrate temperature as the indium composition is increased. An InGaAs layer whose indium composition is at 0.5 is formed on the layer. A high-concentration layer for non-alloy ohmic contact use is formed. A metal electrode is formed on it. As shown in the figure, at an initial stage in which the gradient-composition InGaAs layer is grown, it is possible to avoid that a surface morphology is deteriorated in a part where the indium composition is small even when the growth temperature is as high as 650 deg.C. When the indium composition is at 0.5, the layer can be grown without deteriorating the surface morphology when the substrate temperature is lowered down to 550 deg.C.
