Title: Solid-state laser device
Inventor: OKUMA SHINJI
IPC: H01S3/094
Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To efficiently oscillates a solid-state laser at a high quality in a single longitudinal mode by condensing the light which is repeatedly reflected in an integrating sphere onto the end face of a laser rod. SOLUTION: The pumping light outputted from an LD 1, attached to the opening of an integrating sphere 2, turns into a diffused light after the light is diffused and reflected in the sphere 2. The diffused reflected light is diffused through repeated diffusion and reflection and, when the diffused light is emitted from a lens 3, the light quantity of the light is averaged, and at the same time, the distribution of the spreading angle is also uniformized. The pumping light is condensed onto the end face of a laser rod 4 in the form of a small circular spot. Therefore, not only the intensity distribution but also the spreading angle distribution of the light are uniformized.  In addition, since a part shown by the dotted line in (b) is the mode volume of single lateral mode oscillation and the exciting light can be made coincident with this, all the pumping lights can be used for the oscillation of the laser rod 4. Therefore, high-quality single longitudinal mode oscillation can be obtained efficiently from the laser rod 4.

Title: Manufacturing method of semiconductor device
Inventor: NAKAMURA TOMIO
IPC: H01L21/033
Filed: 1979-12-28
Abstract: PURPOSE:To enable a formation of a submicron opening by a method wherein an opening is formed so as to remain a thin oxide film on an Si oxide film and an Si nitride film installed on a semiconductor substrate, and thereafter, this oxide film is eliminated so as to give no damage to the substrate. CONSTITUTION:An Si oxide film, an Si nitride film and a photoresist film are sequentially crystallized on a semiconductor substrate such as an Si, etc., and taking the photoresist as a mask, an etching is performed by means of a reactive spatter device, etc. so as to remain a thin oxide film (for example: -500Angstrom ). Next thereto, a wet etching is performed by means of an HF-NH4F solvent to completely eliminate the oxide film at the opening part. With this, a micro opening working of an Si oxide film in submicron can be performed and further, a nitride film is coated with the photoresist film before the completion of an opening forming, accordingly, the bonding strength to an electrode metal to be installed on the surface is improved.

Title: Power transmission mechanism
Inventor: SAITO TAKAHIDE
IPC: F16D43/21
Filed: 1999-06-21
Abstract: PROBLEM TO BE SOLVED: To eliminate backlash. SOLUTION: When an input side member 1 receives an input rotating power from a driving source to rotate, a part of the input rotating power is converted into an axial force by the fit between a nearly V shaped recessed cam 5a and a projected cam 5b, and an intermediate member 3 is axially displaced to the output side against a spring 4. As the intermediate member 3 is axially displaced to the output side, a friction clutch 7 is released, and the intermediate member 3 can rotate in relation to a stationary side member 6. On the other hand, when the driving source is stopped, the intermediate member 3 is axially displaced to the input side against pressing energizing force of the spring 4, and the friction clutch 7 is operated to restrict the intermediate member 3 in the direction of rotation with respect to the stationary side member 6 without causing backlash.

Abstract: PURPOSE:To increase an equivalent mass and to obtain optimum structure for a heavy low sound frequency application by employing a heavy soft magnetic material for a core of a moving coil. CONSTITUTION:A full wave rectifier 12 is connected to either a stator coil 2 or a moving coil 5. Thus, the direction of the current flowing to the coil 5 connecting to the rectifier 12 is the same for a first half cycle and a latter half cycle and a magnetic force in the same direction is generated in the coil 5 and since the direction of the magnetic force of the coil 2 not connecting to the rectifier 12 is changed, the coil is acted in the opposite direction in both the cycles, e.g. acted in the attractive direction for the first half cycle and acted in the repulsion direction being the returning direction for the latter half cycle after being restored to zero. Thus, the moving coil 5 is vibrated at a same vibration number as that of an output of an inputted audio amplifier 11, a diaphragm 10 connecting thereto is vibrated and a sound is generated.
