Title: High frequency transmitter
Inventor: KOMATSU SATORU
IPC: G01S7/282
Filed: 1989-07-21
Abstract: PURPOSE:To improve an isolation between transmission systems while reducing a loss produced when switching means are turned on by synchronizing the changeover operation of the switching means with the changeover the conversion characteristics of the multiplier of each transmission system. CONSTITUTION:A high frequency signal generated from a high frequency signal generator 2 is amplified 3 in accordance with a modulation signal from a modu lation signal generating circuit 1 and the amplified signal is fed time-divisionally to transmission systems T1-Tn by a switching circuit 4. The signal is multiplied by multipliers 6 (61-6n) in every system T1-Tn. Isolations between the systems T1-Tn due to the presence or absence of the high frequency signal are improved by using the conversion loss characteristics for the bias voltages VB of the multipliers 6. For an above-described improvement, the changeover of the bias voltages VB applied to the multipliers 6 of the systems T1-Tn is executed in synchronism with the switching of diode switches D-SW1 to D-SWn in the circuit 4 under the control of a controller.

Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor laser of a low threshold value allowing simple mode transmission and having a long life. SOLUTION: A p-type GaAs constriction layer 2 is formed on the surface of an n-type GaAs substrate 1. Thereon, an active layer 5 consisting of an n-type ZnSe layer 3, an n-type ZnSe layer 3, an n-type ZnMgSSe clad layer 4, a ZnSSe light confinement layer 5a and a ZnCdSe quantum well type layer 5b and a ZnSSe light confinement layer 5c, a p-type ZnMgSSe clad layer 6, a p-type ZnSSe cap layer 7, a p-type ZnSeTe contact layer 8 are formed.

On the mesa side, a ZnO compound semiconductor having a lower refractive index than that of the clad layer 6 is formed.  Thereby, a current region flowing to a laser is limited without being expanded and a current flowing to a crystalline defect located outside the stripe is suppressed so as to realize a single mode laser having a long life and low current operation.

Title: Dish drier
Inventor: MIZUMOTO TOSHIKI
IPC: A47L19/00
Filed: 1988-07-29
Abstract: PURPOSE:To improve a drying effect and to shorten a drying time for dishes since a hot current of air with a high speed is sent in a case cover, by a method wherein an air way leading the hot air out of a hot air generator is formed by inclining upward at about an angle of 45 deg.. CONSTITUTION:A hot air generator 11 composed of a fan motor 2, a heating body 3 and an air way 4, is provided in the bottom part of a main body 1, and the air way 4 is formed by inclining upward at about an angle of 45 deg.. A blowoff part 10 is vertically provided with top end of the air way 4, and a blowoff port 9 opened on the side wall of the blowoff part 10 is provided. When a hot current of air is blown out of the hot air generator 11 fitted with the inside of the main body 1, both air capacity and speed becomes large at the blowoff port 9 since a resistance of the blowoff becomes small because of the air way 4 inclining upward at an angle of 45 deg.. It is thus possible to shorten a drying time since the hot air is thoroughly diffused in a case cover 8 and dishes 6 are equally heated.

Title: Method for insulating isolation of semiconductor layer by dielectric
Inventor: OURA JUNICHI
IPC: H01L21/20
Filed: 1985-09-02
Abstract: PURPOSE:To prevent a warp of wafers and to make the film thickness uniform and further to shorten the process time by forming a dielectric insulating film on one principle plane of a semiconductor single crystal substrate and changing opening parts of the dielectric layer into insulators thereby electrically insulating the semiconductor single crystal body from the epitaxial crystal layer. CONSTITUTION:On a surface of a single crystal Si substrate 11, an Si oxide film 13 covered with Si3N4 films 12 and 14 is formed and plural stripe grooves comprising narrow openings are formed on a dielectric film. Then, the epitaxial crystal growth is made by using said openings as nuclei of the crystal growth. If the epitaxial crystal growth is further continued, the epitaxial crystals growing from the adjacent openings get together into one body. The substrate 11 and the epitaxial layer 17 are isolated electrically from each other. By the heat treatment at 1,100 deg.C for 8hr, the oxygen in the Si oxide film 13 is heat- diffused into the opening parts to make the parts into SiOx (x<2) and to form insulators 18. Because the both sides of the Si oxide film 13 are covered with Si nitride films 12 and 14 which prevent the heat diffusion of oxygen, the diffusion of oxygen can be advanced to the side of openings.
