Title: Manufacture of semiconductor laser device
Inventor: FUKUNAGA HIDEKI
IPC: H01S5/00
Filed: 1993-02-25
Abstract: PURPOSE:To manufacture a buried semiconductor laser by selectively removing a diffusion protection layer without providing an etching stop layer. CONSTITUTION:A semiconductor laser device is obtained by depositing a first clad layer 2, active layer 4 sandwiched between a pair of optical waveguide layers 3, and second clad layer 5 on a semiconductor substrate 1 in this order. A first impurity diffusion source film 7 is deposited on these semiconductor layers, and an insulating film 8 is deposited thereon. The two layers composed of the first impurity diffusion source film 7 and insulating film 8 are removed into a stripe shape, except for those on the semiconductor layer region, where impurities are to be diffused. A diffusion protection film 10 which is to be selectively etched in relation to the insulating film 8, is formed on the semiconductor layers 1-5 and the two layers 7 and 8. Impurities are thermally diffused from the first impurity diffusion source film 7, and the diffusion protection film 10 is selectively etched in relation to the insulating film 8. Then second impurities are diffused using the insulating film 8 as a mask.

Title: Heating fixing device
Inventor: KATAYAMA KATSUYUKI
IPC: G03G15/20
Filed: 1993-02-25
Abstract: PURPOSE:To provide a heating fixing device in which the charge of a release layer is prevented in the release layer formed on the surface of a heating roller consisting of a self-exothermic conductive ceramic material, and no turbulence of toner image is caused.

Title: Formation of deposited film
Inventor: ISHIHARA SHUNICHI
IPC: C23C16/30
Filed: 1985-02-28
Abstract: PURPOSE:To facilitate the increase in area of the film, improvement in productivity, and mass productivity, while contriving the improvement in film properties, film-forming speed, and reproducibility, and the uniformity in film quality, by a method wherein an active species A produced by decomposing a compound containing germanium and halogen and an active species B produced out of a germanium-containing compound are separately introduced, which are then made to chemically react by the action of discharge energy, thus forming a deposited film. CONSTITUTION:A discharge energy such as plasma which can form an activating atmosphere is used as the energy to excite and make react the material for forming deposited films. Under the coexistence of an active seed A produced by decomposing the compound containing germanium and halogen and an active species B produced out of the film forming germanium-containing compound, the chemical interaction by these seeds is caused by making discharge energy act on them or promoted and amplified; therefore, film formation is enabled by lower discharge energy than conventional. The formed deposited film does not receive adverse effects such as etching or another action, e.g. abnormal discharge substantially.

Title: Method and device for detecting direction of radio wave
Inventor: AKAHA NORIYUKI
IPC: G01S3/32
Filed: 1989-02-17
Abstract: PURPOSE:To minimize an error caused by a polarized wave of a receiving wave by providing an averaging circuit for applying a processing based on a specific calculating expression to a signal related to a SIGMA mode radio wave and a DELTA mode radio wave on a device using a 4-arm spiral antenna. CONSTITUTION:In a second storage circuit MEM2, data for allowing an amplitude ratio Rm and a phase difference phim to correspond to arrival directions (theta, phi) of a radio wave is stored. In this state, the direction of the radio wave is derived by the right expression. The corresponding relation is a weighted mean of characteristic curves of the amplitude ratio Rm and the phase difference phim against the arrival directions (theta, phi) of the radio wave in a SIGMA mode and a DELTA mode. The above characteristic curves CM, CV are curves obtained by an actual measurement or theoretically, respectively. Also, as for a value of K, when the degree of polarization of a receiving radio wave is obtained by a measurement or theoretically, it is desirable to select K in accordance with its degree of polarization. When the degree of polarization is unknown, an error related (theta, psi) obtained by setting K = 0.5 can be minimized.

Title: Controller for winding switching motor
Inventor: SHIYAMOTO SUMIKAZU
IPC: H02P27/06
Filed: 1993-02-26
Abstract: PURPOSE:To alleviate torque-free feeling at the time of switching the winding while alleviating torque shock. CONSTITUTION:An inverter gate is shut (106), the winding is switched(100), and immediately after turn ON of the inverter gate(112), only exciting current I1d is fed as the primary current of motor(114). At a moment when transient response of the flux of motor ended substantially, primary current I1 including a torque current I1q is fed (116). Since only a time substantially corresponding to a flux time constant tauphiA or tauphiB is required after switching of winding (100) before rising of motor torque, torque-free feeling is alleviated.

Title: Current detector of high frequency welder
Inventor: IDA AKIO
IPC: B29C65/04
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To certainly bond a plastic film or sheet comprising a polyolefinic resin. SOLUTION: A current detector 1 including a resistor 10, a lamp 11 and a CDS 12 is inserted in the current measuring line of a high frequency welder main body for bonding a plastic film or sheet comprising a polyolefinic resin. Since the lamp 11 lights when the high frequency welder main body 3 is started, the luminous intensity of the lamp 11 is detected by the CDS 12. If the current at a time when the lamp 11 develops certain brightness is a value suitable for high frequency bonding, a value based on a resistance change in luminous intensity is set as a reference value in order to set this value. When a plastic film or sheet is bonded, a current flows to increase the emission quantity of light and, when a resistance value exceeds the set resistance value, a current stops and the high frequency welder main body stops and, therefore, bonding can be certainly performed.

Title: Electron beam excitation ion source
Inventor: KAWAMURA GOHEI
IPC: H01J27/08
Filed: 1989-02-16
Abstract: PURPOSE:To reduce treatment time and improve throughput by constituting so that the diameter of a second plasma may be several times larger than that of an electron drawing port. CONSTITUTION:Electrons entering an ion formation room 10 are accelerated by acceleration electric field, collide against BF3, and then generate a dense plasma. At this time, since a porous electrode 8 is placed closer to the electron drawing port 5 so that the gap between the porous electrode 8 and the electron drawing port 5 is equal to or less than 10mm, namely 5 to 6mm, electrons are irradiated to a raw material gas while electrons are not nearly diffused and the diameter A of the generated plasma becomes 1-6 times larger than that of the electron drawing port 5, thus forming a highly dense two-times larger plasma. Therefore, it becomes possible to draw ion efficiently from plasma of this high density by a slit for drawing ion 14, thus achieving a higher ion current density as compared with before.

Title: Method for manufacture of contact via in integrated circuit
Inventor: KUUEIIU FUAN
IPC: H01L21/302
Filed: 1993-03-01
Abstract: PURPOSE: To obtain a contact via in which a flattening material, heavily doped along a sidewall does not exist by setting the dimension of an opening of a second mask layer to be smaller than that of a fist mask layer. CONSTITUTION: A first mask layer 20 is formed on the surface of an integrated circuit for formation of a pattern. A first insulating layer 16, exposed in openings 22 and 24 of the mask layer 20, is half anisotropically etched, and a flattening layer 18 near a contact via to be formed is removed, also. The first mask layer 20 is removed, and then a second insulating layer 26 is formed on the integrated circuit. A mask layer 28 is formed into a pattern to form openings 30 and 32 which decide the position of the to be formed contact via. In this case, the dimension of the openings 30 and 32 are smaller than those of the openings 22 and 24 formed in the first mask layer 20. Thereby a flattening material on the upper surface of the integrated circuit not exposed on a wall surface of the contact via is finally formed.
