IPC: H01L21/337
Filed: 1984-02-06
Abstract: PURPOSE:To produce a GaAS field effect transistor with drain withstand voltage subject to remarkably improved reliability by a method wherein an FET with a drain electrode coming into Schottky contact with an indium, galium, arsenic compound semiconductor layer is contained in a semiconductor device. CONSTITUTION:An n<+> type InGaAs layers 14, 13 other than a drain electrode forming region in a semiconductor substrate are removed utilizing a resist mask until a GaAs surface is exposed. A source electrode 15 is provided on an n type GaAs layer 12 using AuGe/Au by conventional process and then a drain electrode 16 is further provided on the n<+> type In0.5Ga0.5As layer 14. A gate electrode 17 is provided using Al in a recess selectively etched in the n type GaAs layer 12 by conventional process.

Title: Silver halide photographic sensitive material
Inventor: CHINO SHIGEO
IPC: G03C1/08
Filed: 1988-01-30
Abstract: PURPOSE:To obtain a silver halide photographic sensitive material having high sensitivity, superior gradation, and high resistance to pressure by regulating a hardness of a photography constituting layer and adding inorg. S to a silver halide emulsion layer. CONSTITUTION:A degree of swelling of a photography constituting layer is regulated to <=150, and inorganic S is added to at least one silver halide emulsion layer. The degree of swelling of the photography constituting layer is pref. >=80 and <=150, more pref. >=100 and <=140. When the degree of swelling is <80, the sensitivity is undesirably decreased due to decrease of developing speed. When the degree of swelling is >150, remarkable and undesirable decrease of pressure resistance may be caused. Thus, a silver halide photographic sensitive material having high sensitivity, superior gradation, and high pressure resistance is obtd.

Title: Superconducting device
Inventor: KURODA KUNISHIGE
IPC: H01F6/00
Filed: 1987-02-02
Abstract: PURPOSE:To miniaturize and stabilize a permanent switch by a method wherein lead wires for individual superconducting coils are connected to one common gate line so that the maximum value of an electric current flowing through the gate line can be selected to be less than a value of the electric current of the superconducting coils where the maximum electric current is made to flow. CONSTITUTION:First of all a power supply 8 for a permanent switch 5 is started to operate and the permanent switch 5 is turned on; heaters 4, 4' simultaneously heat a gate line 3 and common lead wires for both superconducting coils 1, 1'; these coils are made to be always electrically conductive. At this state, power supplies 6 and 6' are started to operate and the superconducting coil 1' is excited. The greater part of an electric current from the power supplies 6 and 6' flows through a route 6 7<+> 1 7<-> 6 and another route 6<-> 7'<-> 1' 7<+>' 6'; the partial and very small electric current flows through the gate line 3 and the mutually opposite superconducting coils. The electric current which flows through the lead wires additionally heats a part which is still in a superconducting state and contributes to the increase in the resistance of the part; this electric current is rather favorable. In this way, it can reduce the electric current flowing through individual superconducting coils to a minimum or can reverse the polarity of each power supply for the superconducting coils.

Title: Chrominance signal processing circuit for video camera
Inventor: FUJIWARA MOICHI
IPC: H04N9/73
Filed: 1987-02-02
Abstract: PURPOSE:To maintain good color reproducibility even when a video camera is used in either place, outdoors or indoors by controlling whether the output of a color temperature alteration matrix circuit is added to a color signal and a luminance signal according to color temperature or not. CONSTITUTION:When the video camera is used in the indoor, switches 36 and 37 are opened by the L level of a color temperature comparing part. Therefore the output signal of the color temperature alteration matrix circuit 26 is not inputted to adders 34 and 35. As the result of that, the output of the matrix circuit 26 is not added to the output signal YH of a high band LPF 6 for the luminance signal and the output of a LPF 7 for the chrominance signal. On the other hand, when the video camera is used in the indoor, the switches 36 and 37 are closed by the output of the H level of the color temperature comparing part. Therefore, the output of the matrix circuit 26 is added to the filters 6 and 7. As the result of that, the suitable luminance signal for the color temperature and the base band components YH and YL of a chrominance signal can be obtained.

Title: Manufacture of printed wiring board
Inventor: SOEGAWA KOJI
IPC: H05K3/18
Filed: 1990-02-01
Abstract: PURPOSE:To improve the bonding strength between plated resist and a board by forming an oxide film on the surface of the board, forming plated resist thereon, removing the oxide film at a part of a pattern without the plated resist, and thereafter forming a part corresponding to a wiring pattern by plating. CONSTITUTION:An oxide film 40 is formed on the surface of a board. Plated resist parts 41-44 are formed on the oxide film 40. Then, an oxide film 40A at a part of a pattern without resist 12 on the oxide film 40 is removed. Thereafter, a wiring-pattern corresponding part 20 is formed by plating. The plated resist parts 41-44 are removed. Then, an oxide film 40B at the parts corresponding to the plated resist parts 41-44 on the oxide film 30 is removed. Thus, the bonding strength between the plated resist parts 41-44 and the oxide film 40 is increased by forming the oxide film 40 and forming the plated resist parts 41-44 thereon in this way. Since the board can withstand the long plating time, permeation of plating liquid does not occur, and the occurrence of defective gaps can be finally prevented.

Abstract: PURPOSE: To prevent a deformation of an internal pipe when a connecting head shaped like a circular truncated cone is formed at the end of a duplex pipe member by buckling by cutting the end of the internal pipe of the duplex pipe member shorter than an external pipe by a proper length.  
     CONSTITUTION: For shaping a connecting head, a lean metal pipe 2 of a small diameter, a stainless steel pipe, is first inserted inside a thick metal pipe 1 of a large diameter, a steel pipe, and they are welded by clading to make up a duplex pipe 3. The duplex pipe 3 is drilled to shorten only the lean metal pipe 2 of a small diameter so that its end 2' stands behind the end face 1' of the pipe 1 by a proper length. Using a split chuck 7 and a punch 8, the resulting work is buckled to form a connecting head at end in the shape of a circular truncated cone whose front peripheral wall is to be a seat face 5. The pipe 2 is held within the pipe 1 without a deformation caused by a pressure which is applied on the pipe 2 when its connecting head is formed.
