Title: Manufacture of field-effect transistor
Inventor: KOBAYASHI TOSHIMASA
IPC: H01L29/778
Filed: 1991-04-19
Abstract: PURPOSE:To restrain a leakage current from being generated between a mesa- etched channel layer and a gate metal at a high-electron-mobility transistor or the like. CONSTITUTION:An undoped GaInAs layer 2 as a channel layer formed on an InP substrate 1 and an n-AlInAs layer 3 as an electron supply layer are mesa- etched; after that, sidewall parts of the undoped GaInAs layer 2 are etched; recessed parts 6 are formed; an overhang shape is formed. As a result, even when a gate metal 7 is formed, the gate metal 7 does not come into contact with the undoped GaInAs layer 2 due to gaps by the recessed parts 6; a leakage current is suppressed.

Title: Electrophotographic lithography plate
Inventor: TATSUKI SHOJI
IPC: G03G5/14
Filed: 1991-04-18
Abstract: PURPOSE:To reduce the occurrence of fog on the surface of the reverse side coat layer of a zinc oxide electrophotographic lithography plate by keeping the surface smoothness of the layer within 300 to 600 seconds as per Beck's smoothness. CONSTITUTION:The surface smoothness of the reverse side coat layer of a zinc oxide electrophotographic lithography plate is set within the range of 300 to 600 seconds as per Beck's smoothness. In this case, if the Beck's smoothness is less than 300 seconds, the surface of the reverse side coat layer is roughened, thereby generating the pitting of pressure fog on the surface of a zinc oxide photosensitive layer. On the other hand, if the Beck's smoothness exceeds 600 seconds, abraded fog tends to occur, due to slippage at coating, winding and finishing processes. The composition of the reverse side coat layer consists of latex as binding material, water soluble polymer, a waterproofing agent, a conductive agent or the like. Furthermore, pigment containing sericite and 30% or more of sericite component is used as pigment.

Title: Detecting device for incoming wave signal
Inventor: FUJIWARA YOSHINORI
IPC: G01S3/80
Filed: 1985-05-28
Abstract: PURPOSE:To easily detect the level of an incoming signal by controlling the timing of sampling when outputs of a switch array corresponding to a linear array are sampled and obtaining real part and imaginary part data. CONSTITUTION:A sample and hold circuit which samples outputs of the switch array corresponding to the linear array samples the outputs at the 1st timing and the 2nd timing which shifts from the 1st timing by a quarter as large as the wavelength of the incoming radio wave signal within the switching interval of a switch. Data sampled at the 1st timing is stored in a real part memory and data sampled at the 2nd timing is stored in an imaginary part memory. Those data are processed by fast Fourier transform FFT to obtain N pieces of frequency spectrum data with respect to N vibrators. Then, the level of the signal at the angle of incidence of the incoming wave is calculated from the obtained data.

Title: Front hanging type spectacle frame and front hanging frame
Inventor: TEGA TOMOHIRO
IPC: G02C9/04
Filed: 1996-04-11
Abstract: PROBLEM TO BE SOLVED: To prevent the infiltration of light from lateral sides even if a front hanging frame is relatively small, to facilitate the attachment and detachment and to prevent the impairment of the appearance of spectacles by forming covers on both sides of the front hanging frame to shut off the infiltration of the light from lateral sides, providing the inner side of these covers with magnets and claws and mounting the covers at a front frame. SOLUTION: The front hanging frame is mounted at the front surface of the front frame of the spectacles. The front hanging frame is mounted at the front frame by using the magnets 11. The one magnet is fixed to the outside surface of a wraparound endpiece and another magnet is fixed to the inner side of the cover 3 formed on the outer side of the front hanging frame. Then, the front hanging frame is mounted at the front frame by the attraction force of both magnets. The front hanging covers mounted at the front frame of the spectacles exist on the outer side of the wraparound endpieces, thereby shielding a part of the lateral sides when the spectacles are worn. The infiltration of the light is thus prevented.
