Abstract: PURPOSE:To remarkably improve the reliability of a communication system to use an optical fiber by duplexing a transmission line by securing a radio communication route, which uses a space as a propagation path, in addition to the optical fiber only in a certain block of this optical communication system. CONSTITUTION:A radio frequency signal transmitted by a radio transmitter 1 is converted into an optical signal by an electric/optic conversion circuit 2 and inputted to the optical fiber 3. On the other hand, one optical signal branched by an optical branching/coupling circuit 4 is converted into the radio frequency signal by an optic/electric conversion circuit 5 and afterwards transmitted from an antenna 6 for transmission to the space. The other optical signal branched by the circuit 4 is transmitted in the optical fiber 3. The radio frequency signal transmitted from the antenna 6 on the transmission side to the space is received by an antenna 7 for reception and electric/optic conversion 8 is executed upon this signal. Then, optical branching/coupling 9 is executed upon this optical signal together with the optical signal passed through the fiber 3. Thus, the optical signal obtained on the reception side is received and demodulated by a radio receiver 11 after executing optic/electric conversion 10.

Title: Semiconductor device
Inventor: SAKAMOTO TATSUJI
IPC: H01L23/40
Filed: 1981-05-22
Abstract: PURPOSE:To reduce the mechanical strain which is applied to a semiconductor element or an insulating substrate, by providing grooves or slits in a heat radiating substrate, and absorbing the returning deformation of warping due to screw  tightening at these parts. CONSTITUTION:One or more grooves 11 or slits are provided at the part between the screw holes for fixing a heat radiating plate of the heat radiating copper substrate 1 to which insulating substrate 3 comprising alumina is soldered and on the surface on the side of the heat radiating plate. When the insulating substrate 3 is bonded to said heat radiating substrate 1 with solder 2, the warp is generated by the bimetal effect caused by the difference between the linear expansion coefficient of the heat radiating substrate 1 and that of the insulating substrate 3. When the semiconductor device is fixed on the flat heat radiating plate 9 under this state, the groove parts 11 or the slit parts absorb the deformation due to the screw tightening, the strain applied to the insulating substrate 3 or the semiconductor element 5 is alleviated, and the destruction can be prevented.

Title: Light receiving device and circuit-built-in light receiving device
Inventor: FUKUNAGA NAOKI
IPC: H01L31/12
Filed: 1993-04-02
Abstract: PURPOSE:To embody a photodiode which is flat in frequency characteristics and, what is more, which extends in a wide band by burying a first conductivity type diffusion layer whose impurity concentration is higher than a semiconductor substrate between the surface of a semiconductor substrate and a first conductivity type epitaxial layer. CONSTITUTION:An N-type diffusion layer 2 whose impurity concentration is higher than an N-type semiconductor substrate 1 is formed in a photodiode's scheduled area as a light receiving element of the surface of a high impurity concentration first conductivity type or more particularly an N-type semiconductor substrate. Electron-hole pairs produced in the N-type semiconductor substrate fail to contribute photoelectric current by burying the N-type diffusion layer 2 of high impurity concentration into the photodiode. It is, therefore, possible to obtain a circuit-built-in light receiving element which is flat in its frequency characteristics, and what is more, which is capable of operating at high speed.

Abstract: PURPOSE:To stably draw-in a focus by holding the peak value of a focus error signal, and closing a focus servo loop at the time of obtaining a draw detection signal when the focus error signal comes to or below the peak value, at the time of controlling focus draw-in. CONSTITUTION:A focus start signal is inputted, and a diaphragm lens 11 approaches to the signal recording surface of a disk, and the focus error signal FE is obtained.

The counter circuit 4 outputs an ON signal to a gate circuit 5, and closes the focus servo loop, and at the same time, stops the output of a lamp signal generation circuit 7. Thus, a focus draw-in point can be stably detected through the use of a simple constitution.

Filed: 1989-03-28
Abstract: PURPOSE:To obtain the device for removing colored grains from resin pellets without generating the screening defect by static electricity by bringing the air moistened to the extent of not dew-condensing onto raw material surfaces into contact with raw materials transported from a supply hopper to the terminal part of a transporting belt. CONSTITUTION:The pellets flowing down in the bottom end part of the supply hopper 9 are transported to the terminal part of the transporting belt 2 by receiving the wet air which has the moisture content below the satd. moisture and is sent from a wet wind generator 32. These pellets fall between a pair of optical cases 11 and 12. If, for example, the defective pellet with its one surface blacked by carbon comes to a detecting line P, any of photodetecting sensors 17 of photodetecting parts 13 to 15 facing this surface detects the difference between the light quantity of backgrounds 18 to 19 adjusted to nearly the same light quantity as the light quantity of the normal pellet and the light quantity of the defective surface and an ejector 24 corresponding to the position of the sensor 17 operates with a slight delay to flow-off this pellet into a defective pellet discharging trough 27.

Title: Solder paste
Inventor: HIRATA MASAHIKO
IPC: B23K35/22
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To obtain a paste having excellent soldering properties even in reflow soldering in the air and having reliability in the residual dross part of flux after reflow by mixing the flux to which the specified weight ratio of ionic surfactant is added with solder powder. SOLUTION: Flux to which 0.5-10 weight % ionic surfactant is added is mixed with solder powder. The solder powder is preferably a solder paste containing Sn and Zn. The ionic surfactant is chosen so that the solder powder is ionized by the flux and combines with the ion, and is preferably e.g. POE alkyletherphosphoric acid, N-acylaminoacid chloride in view of the reliability of residual dross of the flux in a soldered part after reflow. A firm film is formed on the solder powder by mixing the flux which the ionic surfactant is added with the solder powder, whereby oxidation of Zn during reflow is prevented and the generation of solder balls is restrained.

Title: Optical function element
Inventor: YOSHIKAWA TAKASHI
IPC: H01S5/00
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To attain efficient interaction between the laser light from a surface emission laser and the light in a transverse optical waveguide by intersecting the optical axes of surface emission laser and the optical waveguide. SOLUTION: A surface emission laser and a transverse optical waveguide 3 are formed beneath a post structure 5 while intersecting the optical axes. Since the post structure 5 has a small rectangular plane, linear polarization light is oscillated in single transverse mode in the surface emission laser. Interaction takes place between the light from the surface emission laser and the light propagating through the transverse optical waveguide 3 in an active layer of extremely small volume directly under the post structure 5.  Although sufficient light injection effect from the waveguide can not be attained by a conventional method because of insufficient interaction, the light injected from the waveguide is not dispersed into a large number of modes because a linear polarization light is oscillated in single transverse mode in the surface emission laser and an efficient interaction is attained.

Filed: 1995-04-03
Abstract: PURPOSE: To provide a semiconductor device whose speed is high and which is minute by a method wherein conduction carriers are confined in a one- dimensional slender line. CONSTITUTION: The surface of a silicon substrate 11 has a bend structure in which every bend angle θ12 and every cycle Wp 13 are set, and the width Wc of every channel 16 formed on every protrusion 14 on the surface of the substrate 11 is set at Wp/100<=Wc<=Wp with reference to every bend cycle Wp 13. Since the scattering of conduction carriers is suppressed, it is possible to realize a high-speed and high-gain transistor. In addition, since a drop in a threshold voltage due to a short channel effect is suppressed, the transistor can be subjected to micromachining and integrated highly.
