Title: Epitaxial substrate for semiconductor light emitting element and light emitting element
Inventor: YOSHINAGA ATSUSHI
IPC: H01L33/30
Filed: 1999-06-18
Abstract: PROBLEM TO BE SOLVED: To form an infrared LED in which high speed high output of DDH structure having an n-type layer formed on an n-type GaAs substrate does not cause failure of a thyristor by limiting the maximal carbon concentration to a specified value or below at a predetermined distance from the interface of a second n-type layer to a first n-type layer. SOLUTION: From the results shown in Fig.6, it can be seen that when the compositional ratio of Al between an n-type clad layer and the clad layer at the interface of an active layer is larger than 0.25, absolute value of LED output is smaller than that when the compositional ratio of Al is 0.25 and the output decreases as the active layer is made thin. When the compositional ratio of Al is lower than 0.12, the output increases by making thin the active layer but the absolute value decreases. Consequently, an epitaxial substrate for fabricating an infrared LED in which high speed high output of DDH structure having an n-type layer formed on an n-type GaAs substrate does not cause failure of a thyristor can be obtained and an infrared LED can be fabricated on such an epitaxial substrate.

Title: Form structure in deformed sectional-member centrifugal molding machine
Inventor: YAMADA TETSUYA
IPC: B28B7/00
Filed: 1991-06-18
Abstract: PURPOSE:To obtain high strength concrete having no air gap, high density and a small water-cement ratio by forming an air vent hole in a shape that the air vent hole is penetrated from a molding space to an air vent space. CONSTITUTION:When a molding space 17 is filled with concrete 20, concrete 20 often flows into a closing section 17a in a shape that air is confined. However, confined air escapes to a mold-release space 18 from air vent holes 11f, 12f formed to the closing surfaces 11aa, 12aa of a first separator 11 and a second separator forming the closing section 17a. Air and water escape into the mold-release space from the air vent holes 11f, 12f even when air gaps in concrete are crushed and air and water are pushed out to the closing surface 11aa, 12aa sides by centrifugal force in concrete 20 in the closing section 17a. Accordingly, the closing section 17a is filled densely with concrete 20, thus acquiring high strength concrete having no air gap, high density and a small water-cement ratio.

Title: Target device for laser
Inventor: OTOMO FUMIO
IPC: G01C15/02
Filed: 1994-07-02
Abstract: PURPOSE:To expose light passage position to a diffusion plate and to improve visibility even at a bright location by providing a diffusion member for passing and diffusing visible light and an optical member for enlarging the visible light in one-axis direction and then allowing the optical member to have a plurality of lenses. CONSTITUTION:A target plate 100 consists of a diffusion plate 102, a transmission plate 110, and a plurality of cylindrical lenses 120, 120.... The diffusion plate 102 transmits and diffuses visible light and the transmission plate 110 transmits visible light. Also, the lenses 120 correspond to optical members and the longer direction is laid out nearly parallel to at least one surface side of the transmission part 110. Then, the diffusion member transmits visible light and forms the optical member at least at one surface side of the transmission plate 102, thus forming a plurality of cylindrical lenses 120 where the longer direction of the optical member is laid out nearly parallel. Therefore, light which is exposed on and passes the transmission plate 102 does not cause glaring due to the influence of the diffusion of light, thus improving visibility even at a bright location.

Title: Insulated amplifier including precision voltage-dutycycle converter and low ripple high band width charge balance demodulator
Inventor: RODONII TEII BAATO
IPC: H03F3/387
Filed: 1988-07-12
Abstract: PURPOSE: To provide the isolated amplifier of a high band width without a ripple voltage by replacing a sample-and-hold circuit and a filter inside the isolated amplifier for which modulator/demodulator circuits are combined with a bucket brigade sample- and-hold circuit and turning it to a synthesis isolated amplifier. CONSTITUTION: For the operation of the bucket brigade sample-and-hold circuit 152A, one of the sample-and-hold circuits provided in the circuit 152A performs sampling while the other performs holding excluding the period of signal transition simply by the logic complement signals of the operations 171 and 173. In a switching circuit 63, before a switch 181 makes a contact, obtains the value of a conductor 71 and generates the value in an output conductor 164, the switch 180 breaks the contact and the sample-and-hold circuits 60 and 66 start holding the input voltage of the conductor 161. Inversely, when the switch 181 is closed and the voltage of the conductor 164 samples the voltage of the conductor 71, the switch 181 is opened before the switch 180 is closed. The sample and hold operations of the circuits 60, 66, 72 and 81 overlap excluding the signal transition period.

Title: Reduction of defective products in production of molded part by injection molding, prevention of dusting and increase in safety by applying anticorrosive paint on chip-shaped magnesium alloy
Inventor: HANANO AKIRA
IPC: C09D5/08
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of dusts caused by friction and impact from a chip-shaped magnesium alloy. SOLUTION: The coating of an anticorrosive paint is applied on a chip-shaped magnesium alloy 1 being the raw material of an injection molding magnesium alloy. By the application, oxygen and water in the air are intercepted to prevent the oxidation of the magnesium alloy 1. In the case its oxidation is less, oxidized metal of high temp. m.p. reduces, and the fraction defectives in injection molded parts reduces as well to improve the productivity of magnesium alloy molded parts. Moreover, dusting caused by the friction and impact between the chip- shaped magnesium alloys 1 is prevented with the coating film of an anticorrosion paint 2 as a cushioning material. Furthermore, the anticorrosion paint is also applied to a magnesium alloy ingot matrix as a chip-shaped raw material for preventing oxidation.

Title: Semiconductor integrated circuit device
Inventor: MIYAZAKI YUKIO
IPC: H01L27/08
Filed: 1981-10-27
Abstract: PURPOSE:To contrive the improvement in latch-up resistance for the titled device by a method wherein, in the case of a CMOSIC, the third layer of the same conductive type as a source layer is provided independent of the source layer opposing to the drain layer of each MOS element. CONSTITUTION:An n<+> layer 111 is provided opposing to the drain 104 of an n-MOS transistor B, connected to a source terminal VSS, a p<+> layer 112 is provided opposing to the drain 102 of a p-MOS transistor A, and connected to source terminal VDD. A CMOSIC is formed in the constitution as above and the details which are not included in the above are same as those heretofore in use. When negative surge voltage is applied to an output terminal OUT, an npn element 10 is added between the base and the emitter of an npn element 4, and the actual hFE of the npn element 4 is extremely reduced. When positive surge voltage is applied, the hFE of a pnp element 2 becomes extremely small by adding an npn element 9 in the same manner as above. Accordingly, the section between the base and the emitter is not forward-biased, and no latch-up phenomenon is generated unless surge voltage is considerably large.

Title: Part holder
Inventor: TAKEISHI SHIGEKI
IPC: H05K7/12
Filed: 1999-06-21
Abstract: PROBLEM TO BE SOLVED: To provide a part holder in which a bridge and defective soldering are difficult to form in the case of soldering. SOLUTION: The part holder 20 installed between a part 10 and a printed board 30 is formed in structure in which an opening is formed between the part loading surface of the printed board and the base of the part holder. Accordingly, protrusions 21 are formed to the base of the part holder 20 or a recessed section or a hole is formed at the central section of the base. A spread to a periphery by a capillary phenomenon of solder 32 rising from a through-hole 31 is prevented, and the occurrence of a bridge can be obviated. When a space is communicated with the outside, defective soldering can also be prevented because a gas in the space can escape to the outside when solder rises in the through-hole.
