IPC: H01S3/109
Filed: 1993-02-26
Abstract: PURPOSE:To provide the optical device which can effectively and stably form higher harmonic waves by optical constitution without providing additive means, such as controller. CONSTITUTION:This optical waveguide is constituted by optically connecting a semiconductor laser 5 satisfying quasi-phase matching(QPM) conditions and a QPM-SHG(secondary harmonic generating) element. The QPM-SHG element is constituted by forming an optical waveguide 4 and a polarization inversion part 3 on a ferroelectric crystal element 6 and is provided with the QPM polarization inversion structure. Basic light is made incident from the semiconductor laser 5 on the QPM-SHG element to form the second higher harmonic light. The exit side face 2 of the QPM-SHG element is so formed that a part of the second higher harmonic light formed in the QPM-SHG element is reflected to the QPM polarization inversion structure. The incident second higher harmonic light on the QPM polarization inversion structure is formed again to the light having the same wavelength as the wavelength of the basic light and advancing in the direction reverse to the propagation direction of the basic light. The light is fed back to the semiconductor laser 5.

Inventor: KANAI TOSHIHITO
IPC: H04W76/00
Filed: 1990-02-20
Abstract: PURPOSE:To obtain excellent talking quality even in an environment where a reception level is terribly fluctuated by always selecting plural radio base stations whose communication state is excellent among radio base stations resident around a mobile terminal equipment in the case of making diversity communication between the plural radio base stations and the mobile terminal equipment whose shield effect is different from each other. CONSTITUTION:A mobile communication system consists of plural radio base stations 10, a mobile terminal equipment 20 and an automobile telephone exchange station 30. Then a signal sent from the mobile terminal equipment 20 is received by a peripheral base station 10 and plural radio base stations 10 in the order of larger reception levels are selected among peripheral radio base stations 10 depending on the result of reception to send/receive information between the mobile terminal equipment 20 and the plural selected radio base stations 10. Thus, since the mobile terminal equipment 20 always makes diversity communication with plural radio base stations 10 whose communication station is always excellent, excellent talking quality is obtained even in an environment where a reception level is terribly fluctuated.

Abstract: PURPOSE:To facilitate manufacture and to obtain high frequency and wide band characteristics by providing a laminate structure made of a piezoelectric body and metallic electrode on the elastic surface wave propagation path of an elastic body and by forming an acoustic impedance discontinuous surface on said elastic body. CONSTITUTION:Surface 7 is the acoustic impedance discontinuous surface of elastic body 1, and cutting elastic body 1 at angle alpha to elastic surface wave propagation surface 1' includes a point on the propagation path near the end of the laminate structure and a point right under the structure. Ths structure is provided on the propagation path of elastic body 1 in a strip shape having the length direction at  right angles to the path.

Title: Fluidic flowmeter
Inventor: OSHIMA HIROKO
IPC: G01F1/20
Filed: 1993-03-01
Abstract: PURPOSE:To perform a measurement with high accuracy, in a wide range, in a wide vibration rane and in a wide flow-rate range by a method wherein a pressure takeout port is brought close to the exist of a nozzle, it is made nearly perpendicular to the direction of a jet stream and it is formed to be nearly a rectangle. CONSTITUTION:A pressure takeout port 11 is formed to be an oval which is long in a direction perpendicular to the central line of a jet nozzle 5. Thereby, a pressure sensor measures an average value in a wide range. A change in the jet stream of the nozzle 5 and a change in a pressure on the basis of the generation of vortexes by a return flow to the exit of the nozzle along return flow passages 10a, 10b and by the jet stream are offset and averaged. As a result, an S/N ratio is increased, the measuring accuracy of a flow rate is increased, and the measurable range of the flow rate is expanded. In addition, since the takeout port 11 is formed to be the oval which is perpendicular to the central line of the nozzle 5, fluidic vibrations can be measured even when a vibration range is changed due to a change in the flow rate and the peak point, of the change width of a velocity, which indicates the generation of the fluidic vibrations is moved. The measurable range of the flow rate can be expanded further.

Title: Sheet re-feed unit for image formation device
Inventor: SHIMIZU TADAFUMI
IPC: G03G15/00
Filed: 1987-02-23
Abstract: PURPOSE:To enable controlling the shift of a sheet re-feed roller with less expensive constitution by connecting a drive motor of mono-directional rotation to a rotary axis, fitting a gear having partly cutout teeth to the rotary axis and providing a gear on an operation lever or a member interlocked therewith for engagement with said gear. CONSTITUTION:When a drive motor 8 has rotated, a gear 5 with a part of teeth cut out and fitted to a rotary axis turns concurrently, thereby turning an operation lever 1 or a member interlocked therewith via a sector gear 3 engaged with the gear 5, and moving a re-feed roller to a retreat position. When the drive motor 8 has further rotated, the cutout part of the gear 5 comes to be opposite to the sector gear 3 of the operation lever 1 and said gears 3 and 5 are disengaged from each other, thereby making the operation lever 1 freely rotatable. And the re-feed roller returns to a re-feed position due to the own weight or an energizing force by a spring earlier than in the case of motor drive. Therefore, it becomes possible to control the position of the re-feed roller with a less expensive constitution simply through the control of the drive motor 8 for rotation in a one-way direction.
