Title: Welder for cathode of electron gun
Inventor: TAKADA JUNICHI
IPC: H01J9/04
Filed: 1985-09-25
Abstract: PURPOSE:To prevent the displacement of a cathode, by moving welding electrodes at a high speed and then at a low speed to come into contact with the cathode eyelet of an electron gun to secure the cathode to the eyelet by spot-welding. CONSTITUTION:The cathode eyelet 12 and first, second and third electrodes 13-15 of an electron gun 20 and a cathode 11 held in a cathode holding electrode 4 ar set in prescribed positions. Pressure electrodes 3a, 3b are used to spot-weld the cathode eyelet 12 and the cathode 11 to each other to assemble the electron gun 20. At that time, the electrodes 3a, 3b are moved at a high speed through a distance L2 to the vicinity of the eyelet 12 and then at a sufficiently low speed to a position in which the eyelet is pushed on the cathode 11. The mechanical impact on the cathode 11 is thus reduced to prevent the welded position of the cathode from changing. This results in diminishing the irregularity of the properties of the electron gun 20.

Title: Photodetector
Inventor: SUGA KAZUHIKO
IPC: H01L31/10
Filed: 1991-07-30
Abstract: PURPOSE:To provide a high-sensitivity, low-noise photodiode, of which dark current at the surface is suppressed, by forming a semiconductor layer to be a window layer whose composition varies to have a lower boundary level density when it makes contact with a protective layer. CONSTITUTION:A buffer layer 2, a light-absorbing layer 3, and a window layer 4 are deposited in sequence on an Inp substrate 1 by MOVPE. The window layer includes a lower part of Inp having a greater forbidden band than the light-absorbing layer 3, a middle part of InAlAsP, and an upper part of InAlAs, which has a low boundary level density at the interface with a protective layer of silicon nitride that is formed later. Owing to MOVPE, the composition can be varied as above without causing a lattice mismatch. A photodetector section 6 having a diffused region is formed on part of the window layer. According to this structure, the boundary level density between the window layer and the protective layer is maintained low. This reduces the dark current at the surface, resulting in a high-sensitivity, low-noise PIN photodiode.

Title: Dram control device with page mode function
Inventor: HASHIMOTO YOSHIKI
IPC: G06F12/02
Filed: 1987-08-31
Abstract: PURPOSE:To shorten an access time by selecting a generator based on the compared result of the row address information of a cell during the access at present and the row address of the cell accessed last time. CONSTITUTION:When a microprocessor 1 receives a cycle completion signal S3 or S4 from a timing generator 3 for a page mode or a timing generator 4 for normal access, the microprocessor 1 reads a piece of row address information RA and a piece of column address information CA. Next, when the information RA during an output at present corresponds to that of the pre-cycle, the RA enables the generator 3. Thus, a selector first selects the information RA, and next selects the information CA, and supplies them to a DRAM 1 as an address information ADD. Thus, a word line and a bit line are selected, and then, the cell is selected. When the information during the output at present does not correspond to that of the pre-cycle, the generator 4 is enabled, and the cell of the DRAM 1 is selected in the same way.

IPC: H01L21/205
Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To reduce the threshold current density of a short wavelength semiconductor laser by constituting the thickness of an active layer with the single gain layer to be larger than a specified thickness, and an optical guide layer installed between the active layer and a clad layer. SOLUTION: A clad layer 2 is formed on a substrate 1. An active layer 4 is formed of a single gain layer, whose thickness is not less than 3 nm on the clad layer 2 through an optical guide layer 3. Namely, a single-well layer is formed when quantum well structure is formed, and the single active layer is formed, when structure is not formed. Consequently, the scattering of impurities is reduced and the mobility of holes is improved by setting the active layer 4 to be an undoped layer. A clad layer 6 is stacked and formed on the active layer 4 through a light guide layer 5. Thus, the threshold current density of a short wavelength semiconductor laser can be reduced.

Abstract: PURPOSE: To stabilize a telephone communication by setting current detection sensitivity low so that a telephone set is a little affected by a signal driving a speaker and an external noise in its stand-by state, and putting the detection sensitivity back to stationary one after hook-up operation. CONSTITUTION: A current sensitivity switching circuit 46 which switches the current detection sensitivity of a current detecting circuit 42 is provided in the terminal connecting device 4. When the telephone set 1 is in the standby state, no speaking current flows, so the circuit 42 does not detect any current sets a relay 43 so as to a signal transmission line 3 to the sound source 5 for a speaker through a speaker connecting circuit 44, and the sound source 5 drives the speaker 2. Further, the circuit 46 sets the detection sensitivity of the circuit 42 low.  When the telephone set 1 is placed in the on-hook state, a speaking current flows, so the circuit 42 detects that and forms a channel by setting the relay 43 so that the transmission line 3 is connected to a line switching circuit 6 through a telephone set connecting circuit 45, and the circuit 46 puts the sensitivity of the circuit 42 back to stationary one.

Title: Solid electrolytic capacitor with fuse
Inventor: SEKIGUCHI YOSHINORI
IPC: H01G9/12
Filed: 1990-08-15
Abstract: PURPOSE:To reduce the failure of a solid electrolytic capacitor even when a capacitor element causes shortcircuit to generate heat and solder of the cathode layer is melted the cathode layer and an external cathode terminal are shortcircuited by a solder bridge, resulting in burning by coating a part of a fuse within the boundary between an insulator and the cathode layer and an external cathode terminal with the second insulator. CONSTITUTION:On an insulator 5 that coats parts of the cathode such as solder an external cathode terminal 4 is installed, and fuse 6 is used to electrically connect between the cathode layer 1a that transverses an insulator 5 and is exposed, and the external cathode terminal 4. Further, since the fuse on the upper part of the insulator 5 and the external cathode terminal 4 are coated with the second insulator 7, even when a capacitor element 1 is shortcircuited and heated to cause solder on the cathode layer to be melted, the possibility that the molten solder reaches the external cathode terminal 4 is lowered and the conventional molten solder bridges the cathode layer 1a and the external cathode terminal 4, so that the resultant failure of burning can be remarkably reduced.

Title: Cathode for electron tube and manufacture thereof
Inventor: SUGIMOTO MASARU
IPC: H01J61/067
Filed: 1992-08-13
Abstract: PURPOSE:To reduce consumption of an emitter by ion impact, set an electric resistance of a main material relatively large, and prevent removal of the emitter from the main material. CONSTITUTION:A main material 1 comprises metal, and it has a number of fine through-holes 4. A metal core material 3 is provided in each through-hole 4, and an emitter 2 comprising electron emitting material is filled in a space between the main material 1 and the core material 3. As the emitter 2 is filled between the main material 1 and the core material 3 in the through-hole 4 provided in it, an exposed surface of the emitter 2 is so small that it is less likely to receive ion impact. Since the emitter 2 is held between the main material 1 of metal and the core material 3, the emitter 2 can be held strongly by thermal expansion of the main material 1 and the core material 3. In addition, because the main material 1 has the through-holes 4, its volume to the whole body of a cathode is small, so that an electric resistance of the main material 1 can be set high. As the through-holes 4 are formed through the main material 1, a volume of the emitters 2 to the whole body of the cathode can be set relatively large.
