Title: Semiconductor light-emitting device
Inventor: ANAYAMA CHIKASHI
IPC: H01S5/042
Filed: 1989-08-09
Abstract: PURPOSE:To increase oscillation power at a low-threshold value and stabilize oscillation mode by enabling a first clad layer to have a downward ridge-shaped part, a fourth clad layer to be in ridge shape, and by limiting current path through an active layer with first and second current block layers. CONSTITUTION:An SiO2 mask is coated on a contact layer 12, the contact layer 12, a spike-preventing layer 10, and a fourth clad layer 9 are etched to an etching stopping layer 8 and are eliminated, thus leaving 5mum wide stripe ridge shape. An n-GaAs is allowed to grow selectively on the etching stopping layer 8 for embedding both sides of the fourth clad layer 9, thus forming a second current-block layer 11. Then, after eliminating the SiO2 mask, P<+>-GaAs is allowed to grow, thus forming a 3mum thick contact layer 13. A P-side electrode 14 and an N-side electrode 15 are formed on the contact layer 13 and under a semiconductor substrate 1, respectively. Thus, a visible light laser with a ridge-shaped clad layer is completed above or below with (AlxGa1-x)0.5In0.5P as an active layer.

Title: Head for dot printer
Inventor: OBATA HIROYUKI
IPC: H04N1/52
Filed: 1985-09-18
Abstract: PURPOSE:To obtain a fine finished printing with a uniform quality of longitudinal, lateral, and diagonal lines, by constituting a head which provides rhombic dots with the diagonal lines of these dots arranged in a scanning direction. CONSTITUTION:Square dots 4 that are made of heat generating elements are arranged in two lines in the main scanning direction X, and electrode layers 7 serve for the dots 4 in the upper line and electrode layers 8 serve for the dots 4 in the bottom line respectively for application of voltages; and all of the facing electrodes for the respective dots 4 use a common electrode 9. In the above stated manner, it is feasible to perform printing at dot positions at a specified pitch and also at dot positions with a half pitch off. If a diagonal line is printed, therefore, with the head, a smooth line without an offset (see diagram 5b) may be obtained; and if a longitudinal or lateral line is printed, a line with offsets (see diagram 5a) may be obtained. If the results of the printing are observed, offsets are more conspicuous in a diagonal line than a longitudinal or lateral line. If the head is used, therefore, an overall impression of the line qualities is uniform, resulting in a better finish.

Title: Inter-vehicle communication system
Inventor: HOSHINA SATORU
IPC: B60W30/00
Filed: 1999-07-21
Abstract: PROBLEM TO BE SOLVED: To realize stable communication between vehicles without instantaneous interruption and break owning to the drop of reception power by installing plural antennas so that heights from ground differ at the time of installing them in an on-vehicle transmitter/receiver and removing the influence of reception power caused by road reflection as a result. SOLUTION: Transmission signals from the other vehicle are received by the antennas 101 and 102 of a reception vehicle. The heights of them installed in the vehicle differ. When the antennas are installed in a vertical direction, a phase difference Φ between a direct wave and a reflected wave in the antennas 101 and 102 approximately becomes Φ=4πHt(Hr+ΔHr)/(λD), where Ht is the height of the transmission antenna, Hr is the height of the reception antenna, λ is the wavelength of a carrier and D is vehicular gap. The change in antenna height ΔHr consequently generates the phase difference Φ.  When the phase difference Φ is odd times as much as π, the phases of the direct wave and the reflected wave, which are reversed in the antenna 101, become in-phase and they are mutually strengthened Then, the attenuation of large reception power is removed.

IPC: G03G21/00
Filed: 1983-11-04
Abstract: PURPOSE:To suppress the decrease in durability of a photosensitive body after polishing by incorporating a metal having a smaller ionization tendency than hydrogen or the compd. of said metal to the polishing agent. CONSTITUTION:The amt. of copper to be incorporated into a polishing agent needs to be determined by taking the polishing effect in the stage of polishing and the influence of the characteristic of a photosensitive body by the copper adsorbed on the surface of a photosensitive drum 9 and diffused into the photosentitive layer in the stage of polishing into consideration. The copper is preferably incorporated at 0.001-50pts.wt. by the weight of the polishing agent consisting of cerium oxide, etc. into said agent and is more preferably incorporated therein at 0.005-50pts.wt. Silver, gold, platinum or at least two kinds among these metals may be used besides copper as the metal to be incorporated into the polishing agent; further the inorg. compd. contg. said metals may be used as well. Liquid isopropyl alcohol is used as a dispersant for the copper and a pasty (for example, silicone oil, etc.) dispersant may be used as well. The polishing agent is coated on the surface of the drum 9 or is coated on a buff 36 or polishing by buffing is equally well. The polishing by buffing has the effect of making uneven polishing difficult to arise.
