Title: Manufacture of indirectly heated cathode structure
Inventor: TAKANASHI YUKIO
IPC: H01J9/04
Filed: 1981-06-30
Abstract: PURPOSE:To enable a welding with a high welding strength and a high reliability to be performed by welding an inner and an outer sleeve, which constitute an indirectly heated cathode structure, by use of laser light after the clearance formed between the inner and the outer sleeves is removed by making them in close contact with one another. CONSTITUTION:An inner sleeve 4 is subjected to oxidation treatment carried out at 900-1,100 deg.C in a furnace of wet hydrogen for 5-30 minutes so as to form an oxidized film 41 over the surface of the inner sleeve 4. On the other hand, after the circumference wall of a base metal 2 fitted into one end of an outer sleeve 3 is fixed to the sleeve 3 by a resistance welding, the inner sleeve 4 is inserted into the outer sleeve 3. Next, a core metal is inserted between the inner and the outer sleeves 4 and 3 so that the core metal touches the inner sleeve 4. Then, the outer sleeve 3 is deformed by applying external pressure so as to make the inner and the outer sleeves 4 and 3 to closely touch one another and  to remove the clearance between the sleeves 4 and 3. After that, a laser light (L) is irradiated on a given part of the outer sleeve 4 from almost a perpendicular direction so as to make the inner and the outer sleeves 4 and 3 to be welded and fixed together and a welding point 3a.

Patent JP-S61261907-A (JP)
Title: Amplifier
Inventor: JINNO KEIJIRO
IPC: H03F1/30
Filed: 1985-05-15
Abstract: PURPOSE:To make instantly a DC bias stable even when an input signal level changes by providing a voltage limit element in parallel with the DC negative feedback resistor. CONSTITUTION:The voltage limit element 37 is connected across a resistor 10 forming a DC feedback circuit and since the element shows a high resistance at the steady-state and shows a low resistance at the transient state, the time constant is reduced to decrease the recovery time. When the input is changed over from a large amplitude into a small amplitude, the potential difference across a capacitor 20 is nearly constant. Since a transistor (TR) 37 of diode connection exists in parallel with the resistor 10, the potential difference across the resistor 10 does not exceed 0.7V. Thus, a TR 33 starts operation at an earlier time.

CONSTITUTION:Plural metal blocks 10 of a round-rectangular form having two planes, each being formed by cutting the sides of a round columnar body having curved faces 10a of a given curvature radius on its ends from two directions in parallel, are set on a base block 11 in such a way that the planes 10b are closely contacted with oblong holes 12 formed in the block 11. An adhesive curable by photo-polymerization, e.g., two-component curable adhesive, is packed into the apertures between the holes 12 and the metal blocks 10 for fixation, and the opening of the lens 14 is of a round-rectangular shape. In such a mold, since the metal blocks 10 are arranged so that their planes are closely contacted with each other, no falling occurs in the arraying direction and the off-centering of the optical axis of the lens 14 can be avoided.

Title: Semiconductor memory device
Inventor: HAGIWARA YOSHIAKI
IPC: H01L27/00
Filed: 1987-04-24
Abstract: PURPOSE:To reduce an occupied area of a memory cell by storing data in a capacitor connected between the other source drain region of a 1st MIS transistor (TR) and the gate of a 2nd MIS TR. CONSTITUTION:In the case of write, a selected input word line WL1 is changed from L to H and the TR M1 is turned on. Then, the electric potential of one counter electrode of the capacitor C1 becomes equivalent to the electric potential of a bit line BL. This electric potential is kept as it is in the capacitor C1 for storage operation. Then, in the case of the operation of read, the initial electric potential of the bit line BL is L as equivalent to the electric potential of the unselected word line, while the selected output word line WL2 only is H. At that time, the electric potential of the gate g2 of the TR M2 is different according to the stored data, while the TR M2 is already in the state of either on or off. Consequently, the output is carried out according to the data based on whether or not H of the selected word line WL2 is transmitted to the bit line BL.

Title: Helium leak detector
Inventor: TAMURA YOSHIICHI
IPC: G01M3/20
Filed: 1994-04-15
Abstract: PURPOSE:To reduce the transmission of helium gas for highly accurate measurements by connecting the common connection of a three-way valve to a test port, one of the connections of the valve to a calibrated leak, and the other connection to the atmosphere. CONSTITUTION:A pipe leading to a test port 2 is connected to the common connection of a three-way solenoid valve 3 via a two-way solenoid valve 21. One of the connections of the valve 3 is connected to the atmosphere and the other connection is connected to a calibrated leak 4. When a drive power source is turned off, the valve 21 is closed while the valve 3 is opened to the atmosphere. During measurement with a subject T to be tested mounted on the port 2, the valve 21 is closed while the valve 3 is opened to the atmosphere. To perform calibration, the power source is turned on to open the valve 21 and the valve 3 is connected to the leak 4. To remove the subject T to be tested after leak measurements are completed, the valve 21 is opened to connect the valve 3 to the atmosphere if the atmosphere need be introduced into a test-port pipe. Therefore, the supply of helium gas from the leak 4 to the space between the valves 2, 3 is shut off and the space is opened to the atmosphere, so that the transmission of the helium gas can be reduced.
