Patent JP-S56124286-A (JP)
Title: Semiconductor laser device
Inventor: MITO IKUO
IPC: H01S5/00
Filed: 1980-03-03
Abstract: PURPOSE:To permit a high-output fundamental transverse mode oscillation by a method wherein the refractive indexes of the semiconductor layers surrounding an active layer are made smaller than that thereof, and the stripe width for injecting circuit into the active layer is made smaller than that thereof. CONSTITUTION:By using an SiO2 strip mask 12, Cd is diffused into an N type InP substrate 1 to produce P type current blocks 2. Then, an active layer 4, P type InP5 and P type InGaAsP6 are piled thereon, and a mesa etch is applied thereto reaching the layer 2 by using an SiO2 mask 13. N type InP7 is again deposited to fill the mesa grooves. Thereafter, conventionally, the P side is coated with Au- Zn 10, and the N side with Au-Sn 11. By said constitution, the width of the current injected into the active layer 4 is restricted within the width W0 of the layer 3, so that the radiative recombination of carriers is strongest at the center portion of the active layer, where the largest again distribution is formed. Accordingly, even though the active layer width Wa is approximately three times as wide as those of conventional devices, a hihg-output fundamental transverse mode oscillation can be obtained.

Title: Heating apparatus
Inventor: NAKANO CHIKAO
IPC: F24C15/20
Filed: 1983-02-18
Abstract: PURPOSE:To improve the maintainability by a structure wherein the exhaust opening, which is provided on a slidable heaing part outer case, is abutted against a cabinet exhaust guide so that the exhaust tube of a heating chamber extends through the exhaust opening into the exhaust guide. CONSTITUTION:The exhaust, which emerged from a combustion chamber 2 and a heating chamber 1 through an exhaust tube 8, is discharged through an exhaust guide 6 from the rear upper part of a cabinet 7 to the outside of the apparatus. In the structure as mentioned above, because the exhaust guide 6 and the heating part outer case 5 are abuttingly joined with each other so as to form an exhaust opening 5a at the upper part on the rear surface of the heating part outer case 5 and only the exhaust tube 8 pierces the exhaust opening 5a, the heating part 1 can be drawn out forward with no trouble along a rail 10. Thus, the improvement of maintainability is contrived.

Title: Gas fuel low oxygen burner and control method thereof
Inventor: TOKUDA KIMIYO
IPC: F02B3/06
Filed: 1993-02-16
Abstract: PURPOSE:To prevent a rise in the temperature of metal of a flame holder by securing ignition stability of a flame even when the concentration of contained oxygen changes sharply because of abnormality in a diesel engine or the like in a gas fuel burner using a gas with a lower concentration of oxygen such as exhaust of the diesel engine or the like as combustion air. CONSTITUTION:An opening part is provided communicating between the outside and the inside of a primary air cylinder 03 while being provided with an opening adjusting damper 101 and an output of a flame detector 08, the temperature of metal of a flame holder 07 and the concentration of oxygen in combustion air 22 are detected to adjust the opening adjusting damper 101 based on the results so that the flow velocity of a primary air 23 is adjusted as being blown into a fire furnace 13 from the primary air cylinder 03. If the flow velocity of the primary air 23 is low. the ignition of a flame is stabilized though the concentration of the oxygen is very low. The flow velocity of the primary air 23 is adjusted by the concentration of the oxygen at the moment. Moreover. the flow velocity is checked by the output of the flame detector 08. When the flow rate of the primary air 23 is too small, there is possibility that the flame holder 07 may be overheated to cause a burning loss. The temperature of metal of the holder is also checked.

Title: Drum flange
Inventor: KURATA MITSURU
IPC: G03G21/00
Filed: 1981-02-25
Abstract: PURPOSE:To prevent a flange from being attached reversely to the photosensitive drum of an image forming equipment, by providing projections on the surface of the flange. CONSTITUTION:On the surface of a flange 1, a bearing 2 supporting a drum 3 by axis is formed projecting. A couple of pawls 7 extending radially are fixed near the bearing 2, and the tip of each pawl 7 is bent at the outer circumference of the flange with an angle alpha (70-80 deg.) to the flange surface, and is positioned a little more bit inwardly than the outer diameter area of the flange. Consequently, if the flange 1 is to be fitted to the drum 3 reversely, the tips of the pawls 7 strike the step part 4 of the drum and the flange 1 is not fixed at a normal position. Further, a long-sized bolt 5 having enough length for a normal fitting state does not reach an opposite screw part 8, so that the drum is not equipped. Further, even when the flange 1 is placed on the drum 3 being shifted, the pawls 7 do not strike the upper end surface to prevent an end surface 3' from being flawed.

Filed: 1997-02-12
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of the defect caused by the fluctuation in the environmental temperature and to obtain high reliability by adhesively fixing a flexible wiring substrate to the transparent substrate of a display element between the connecting part of an input signal wiring substrate and a semiconductor chip. SOLUTION: Flexible films are used for base films 4a to 4d. A connecting electrode 6, which is led from the pixel electrode of a liquid crystal element, is connected to an output electrode 7 of the TCP, which supplies driving waveforms to the pixel electrode, through an ACF 9. An input electrode 8 of the TCP is connected to a connecting electrode 12 of a PCB substrate 13, which supplies electric power and control signals to the TCP, through an ACF11. The TCP and a glass substrate 1b are connectively fixed between the connecting part of the TCP and the PCB substrate and a driving semiconductor chip 3. Thus, even though a shearing stress is generated to the TCP in the edge direction of the substrate 1b, the stress is absorbed by the flexibility of the film 4c and no adverse effect is given to the connecting sections of the electrodes and other members.
