Title: Driving force transmission device
Inventor: INUI MASAKI
IPC: F16D43/284
Filed: 1989-06-22
Abstract: PURPOSE:To improve releasing ability of a vehicle from a stacked condition by adopting a temperature sensing member which projects to the side of a frictional clutch when reaching a specified temperature as a spacer for supporting the frictional clutch on one side of an axial direction. CONSTITUTION:When a vehicle is under a stacked condition, high differencial rotations are generated between an outer case 11 and an inner shaft 12 for a long period, and a temperature of a frictional clutch 10b reaches a specified value, a spacer 18 made of form memory alloy is deformed and to project to the side of the frictional clutch 10b. As a result, the frictional clutch 10b is strongly pressed by an operation piston 13 and the spacer 18 to be under a locked condition, while the outer case is integrally connected to the inner shaft 12. The high-frictional condition of the frictional clutch 10b is thus eliminated and thereby damage such as seizure is prevented from occuring. In addition, the transmission torque between the outer case 11 and the inner shaft 12 is increased to improve releasing ability of the vehicle from the stacked condition.

Title: Display method for mark
Inventor: NAITO HIDEO
IPC: G09F7/16
Filed: 1991-07-01
Abstract: PURPOSE:To display a mark having a metallic luster in three dimensions with a simple process and at a low cost by providing a color processed layer around the recessed part of a mark shape provided in a transparent plate member and covering it, containing its peripheries, with a metallic color sheet. CONSTITUTION:A recessed part 1a having a mark shape is formed on one surface of a resin mold lens 1, which being a transparent plate member, a colored processed layer 9 provided around it. Whereby, a negative mark shape is depicted. After that operation, when a metallic color sheet 7 superimposed thereon, a mark having a metallic color tone and a metallic luster will be relieved in three dimensions. Since the colored processed layer 9 is secured to the resin mold lens 1, the metallic color sheet 7 takes no part in the positioning of the mark shape. Thus, it is enough that the peripheries of the metallic color sheet 7 overlap on the colored processed layer 9, so that some misalignment can be allowed.

Title: Optical information recording and reproducing device
Inventor: MARUYAMA KOICHI
IPC: G11B7/1374
Filed: 1994-07-13
Abstract: PURPOSE:To remove the chromatic aberration of an optical recording and reproducing device with a simple constitution of the device by composing a collimator lens of a single lens and compensating the chromatic aberration of an objective lens. CONSTITUTION:A collimator lens 11 is composed of a single lens. An objective lens 12 is subjected to the chromatic aberration compensation so that the synthesized chromatic aberration with the collimator lens 11 composed of a single lens is canceled and its backfocus when it is alone is made shorter as the wavelength increases. Namely, when the collimator lens 11 is adjusted so as to transmit a parallel light beam with the standard wavelength of a semiconductor laser 10 and the wavelength of the oscillating luminous flux of the semiconductor laser 10 changes to be lengthened, the emitted luminous flux from the collimator lens 11 becomes a loose divergent beam, in this case, by excessively compensating the chromatic aberration of an objective lens 12, this divergent beam is converged so that the image forming point on the information recording surface 14a of an optical disk 14 is not changed.

Abstract: PURPOSE:To effect laser oscillation highly efficiently and stably, by producing a plasma by the primary electric discharge effected by a plasma focus mechanism, and exciting the atoms of a metal vaporized in a ceramic tube by a high-density plasma produced by the secondary electric discharge. CONSTITUTION:A plasma mechanism 21 with a double-tube structure which is composed of outer and inner cylindrical electrodes 20, 21 and adapted to produce a pinch plasma by a primary electric discharge is formed on one side of a laser oscillation tube 10.

A second anode 19 is provided at a position opposite to the metal source 18 so that the anode 19 opposes the electrode 12 in the axial direction of a ceramic tube 11 which accommodates the electrode 12. By the secondary electric discharge occurring between the anode 19 and the electrode 12, a uniform plasma having a high electron temperature and a high density is produced within the ceramic tube 11 so as to excite the atoms of a metal vaporized by the pinch plasma and flowing in the ceramic tube 11, thereby forming an inverted population necessary for laser oscillation. Thus, it is made possible to obtain laser oscillation stably and highly efficiently.

Title: Speed control system of magnetic disc device
Inventor: IWASE KAZUHIKO
IPC: G11B21/08
Filed: 1982-09-16
Abstract: PURPOSE:To attain surely efficient head drive control, by using a speed correcting value at each fixed period in a deceleration period when the head is shifted to an objective track so as to reduce the amplitude of fluctuation in the objective speed signal between tracks. CONSTITUTION:When the head reaches the center of a prescribed track, an objective speed signal generating circuit 13 sets a track value Tc. Taking the value Tc as 10 and a variable (a) as ''0'', the objective speed signal V is K.101/2. When the head is shifted from the center of the track value 10 by >=1/4, an off- track signal Tf is outputted from the circuit 10. A pulse Tb is outputted at a point between track values 10 and 11, and in taking the (a) as ''1'', the signal V is K.9.51/2. The (a) being the speed correcting value is set to be ''1'' between the pulses Tb and Ta at the output period of the signal Tf. Thus, the circuit 13 outputs the signal V of the head shifted to the objective track value Td. This signal V is set with very small speed regulation by using the correcting value (a).
