IPC: G02B6/122
Filed: 1992-07-03
Abstract: PURPOSE:To easily form a semiconductor laser element so as to have a flat surface without forming a dielectric film for etching stop, by the so-called twice growth and in a self-alignment manner. CONSTITUTION:On a first conductivity type semiconductor substrate 1, the following are grown in order; a first conductivity type clad layer 4, an active layer 5, second conductivity type clad layers 6, 8, a second conductivity type contact layer 10, an (AlxGa1-x)As etching stop layer 31, and an (AlyGa1-y)As cap layer 32 (y<x). After a stripe type mesa part 40 is formed, a first conductivity type current blocking layers 11 are buried in both sides of the mesa. Resist 18 is spread, and the surface side of the resist is eliminated by ashing. Thus unnecessary crystal 30 on the mesa part 40 is exposed. The crystal 30 on the mesa part 40 and the cap layer 32 just under the crystal 30 are etched by using specified etching solution. The resit 18 and an etching stop layer 31 are eliminated.

Title: Keyboard device
Inventor: MACHIDA MINORU
IPC: G06F3/023
Filed: 1983-09-27
Abstract: PURPOSE:To decrease the number of connection lines by arraying impedance elements in the X and Y directions of a keyboard matrix in series and outputting the depression output of a key switch as variation in impedance. CONSTITUTION:A connection cable 3 consists of two signal lines 3A and 3B, which are connected to series connection resistances RH1...RH5, and RV1...RV4 in the X and Y directions of the key matrix. Respective rows and columns of the key matrix are connected to respective connection points of those series resistances, so a key which is depressed connects its row and column. For example, when a key switch K33 is pressed, resistances RV3, RV4, RH3, RH4, and RH5 are connected in series. Therefore, the impedance of the keyboard viewed from the main body side varies corresponding to a depressed key.

Title: Manufacture of impregnated coil
Inventor: ICHII KAZUHIRO
IPC: H01F41/12
Filed: 1988-07-18
Abstract: PURPOSE:To facilitate the separation removal work of an unnecessary resin by disposing a non-adhesive sheet material onto a boundary surface with the unnecessary resin of the outer circumferential section of a coil on the outermost circumference of the coil. CONSTITUTION:A non-adhesive sheet material 9 is arranged between the outermost circumferential section of a coil 5 and a non-adhesive tape 4. The sheet material 9 has thin thickness, and is disposed onto the whole surface of the outer circumference so as to be formed in width slightly wider than the coil 5 so that an unnecessary resin can be separated and gotten rid of completely. On the other hand, the non-adhesive tape 4 is wound on the outer circumferential section of the non-adhesive sheet material 9 for clamping and fixing a conductor 1, inter-layer paper 3 and further the sheet material 9. The needless resin can be isolated and taken off easily because of inferior affinity with an impregnating resin of the non-adhesive sheet material 9 arranged onto the boundary surface of the coil 5, and the non-adhesive tape 4 is also removed at the same time together with the non-adhesive sheet material 9.

Title: Word processor
Inventor: MAKIHARA KAYOKO
IPC: G06F17/21
Filed: 1986-07-28
Abstract: PURPOSE:To instantaneously enable an operator to recognize errors and to eliminate the time loss by producing a setting unable signal when the data input exceeds one of the left and right margins in a setting mode of a column layout. CONSTITUTION:When a column key is pushed while a text is compiled by a word processor, the text screen displayed on a display 3 is fixed. Then it is decided based on a current line memory 100 of a RAM19 whether a current cursor line is coincident or not with a line set previously. If said cursor line is set lower than the prescribed line, a message of a column layout setting mode is displayed with inversion. At the same time, a text cursor K is shifted to the head position corresponding to the set mode. While the text is scrolled up on a screen until the cursor line is equal to the prescribed line when it is decided that the cursor line is set higher than the prescribed line. Thus an operator operates keys to set an appropriate column layout with reference to the text set at a position lower than the prescribed line having no superposition on the text and also related to tabulation.

IPC: H04L12/26
Filed: 1999-06-23
Abstract: PROBLEM TO BE SOLVED: To reduce testing cost by dispensing with an external testing function by deciding a fault by comparing an average value calculated from a level of a test signal inputted from a sound input line with an expected value. SOLUTION: A folded loop of test signal is formed in an interface device, by connecting a test signal generator 18 with a D/A converter 12 with a switch 19 and connecting output and input lines 14 and 15 with a switch 20 under an instruction of a host processor 11 at self-diagnosis. A test signal digitally converted by an A/D converter 17 is sampled for n times by a signal level detector 21, and average sampling value is calculated. The average value is determined by whether it exists within a range of expectation values by an acceptance deciding device 22, if it exists within the range, a fact that it is normal is notified to the host processor 11 and when it exists out of the range, a fact of a fault is notified to the host processor 11.  Thus, since operation test is performed without external connection of equipment for test, required cost for construction test environment is reduced, and on-line fault diagnosis of product is enabled.
