Title: Semiconductor laser module
Inventor: TOJO MASAAKI
IPC: H01S5/00
Filed: 1989-04-21
Abstract: PURPOSE:To prevent the fall of coupling efficiency caused by the drift of the optical axis of an optical fiber even when distortion occurs to a housing by heat by fixing a lens and the optical fiber to a point symmetry position to the edge of a square barrel provided in the housing. CONSTITUTION:A lens semiconductor laser module which optically couples light outputted from a semiconductor laser 1 and the optical fiber 3 by using one lens 2 is constituted. That means, a section which is vertical to the center axis of the square barrel 8 is fixed to the housing 9 and the lens 2 and the optical fiber 3 are fixed to the opposite sides of a quadrangle which is constituted of the section of the square barrel 8. Therefore, since the lens 2 and the optical fiber 3 and fixed to the identical substance, the lens 2 and the optical axis of the optical fiber 3 are hardly drifted. Thus, the coupling efficiency hardly falls.

Title: Optical recording medium
Inventor: UENO OSAMU
IPC: G11B7/257
Filed: 1990-04-20
Abstract: PURPOSE:To allow high-speed rewriting and to obtain excellent signal quality, such as C/N and jitter, by providing a heat conduction controller which has the thermal conductivity higher than the thermal conductivity of a recording material and has the thermal conductivity lower as the temp. is higher. CONSTITUTION:The radiation of heat from a recording layer 3 is accelerated by the effect of a heat conduction control layer 4 made of Si having the high thermal conductivity in the peripheral part of an irradiated point where the temp. is low at the time of a 'high temp. heating and rapid cooling treatment' which is at the time of recording, by which the sufficient cooling rate is assured and recrystallization is prevented. On the other hand, the heat radiating effect is weakened by as much as the decrease in the thermal conductivity of the layer 4 in the central part of the irradiated point where the temp. is high, by which the heat loss quantity in the central part of the point is lowered and the degradation in the recording sensitivity is prevented. The output of a laser beam is low and the recording layer 3 is not exposed to a high temp. at the time of the 'low temp. heating and slow cooling treatment' at the erasing. Since the cooling rate over the entire part of the irradiated point is low, the low temp. heating and slow cooling treatment of the recording layer 3 is not hindered in spite of the presence of the layer 4.

Filed: 1988-04-26
Abstract: PURPOSE:To obtain uniform washing effect by constituting the title washer so that vibration frequency in an ultrasonic washing vessel is periodically fluctuated and the articles to be washed are turned in the ultrasonic washing vessel while washing the articles. CONSTITUTION:The materials to be washed such as a tableware are placed on a rotary basket 3 in an ultrasonic washing vessel 1 and washed while rotating the materials with a driving motor 4 and a changeover switch 5 is subjected to on-off motion according to rotation of the driving motor 4 and thereby the capacitor capacity of a parallel resonance circuit is changed and resultingly vibration frequency is changed at every constant period and actuated. Therefore since the materials to be washed such as the tableware are moved in the ultrasonic washing vessel 1, the materials commonly receive power of vibration in such a stag that the materials are passed through an uneven region of ultrasonic vibration and uniformly washed. Further stationary wave is changed because the vibration frequency is changed and furthermore the power of vibration is given to the materials to be washed to uniformly wash the materials. Uniform washing is enabled by such a synergistic effect.
