Title: Method and apparatus for measurement of secondary-electron emission capability
Inventor: FURUYA NOBUAKI
IPC: G01N23/22
Filed: 1997-05-27
Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus in which a secondary-electron emission capability can be measured easily and precisely in a low-vacuum environment by a method wherein a gas is ionized in a prescribed gas atmosphere between an anode electrode and a plurality of cathode electrodes in which substances to be measured are arranged and the amount of electric charges flowing in the cathode electrodes is measured. SOLUTION: A substance A 10 to be measured and a substance B 11 to be measured are set respectively on a cathode electrode A 3 and a cathode electrode B 4. An atmosphere gas such as He or the like is ionized by an ionization part 5. Charged particles as cations are impinged on the substances A 10, B 11. Then, the substances A 10, B 11 emit secondary electrons, and electric charges to which the charged particles are added flow to respective electric-charge-amount measuring parts 6, 7, and the total amount of the electric charges flows to an electric-charge-amount measuring part 8. In this case, when the electrodes A 3, B 4 in a plurality are arranged so as to be regarded as equivalent, the amount of the electric charges of the charges particles flowing into the substances A 10, B 11 becomes equal.  At this time, when the value of the secondary-electron emission of, e.g. the substance A 10 is known, the secondary-electron emission capability of the substance B 11 can be computed by a secondary-electron measuring part 12 on the basis of the total amount of electric charges of the measuring parts 6, 7.

Title: Diffusion of boron
Inventor: MURAOKA KIMIHIRO
IPC: C30B31/02
Filed: 1979-10-24
Abstract: PURPOSE:To shorten the diffusing process, by opposing the disk-shaped Si diffusing source, on one side of which (B2O3)2 is applied, and the back of the Si disk on a jig, so that the diffusing source occupies the front position with respect to the carrier gas and both disk faces are at a right angle with the flow of the carrier gas. CONSTITUTION:The sides of an N type Si substrate 20 other than a surface 3 on which B is diffused is coated by SiO2 4. The diffusing source 10 is so configured that one side of the Si disk 1 is coated by (B2O3)2 2. The substrate 20 and the diffusing source 10 are arranged on the jig 5, so that the back side of the surface 3 of the substrate 20 and the coated surface of the diffusing source 10 oppose each other. Ar gas containing moisture is flowed in the arrow direction in a quartz tube 9, which is heated, thereby B is diffused. At this time, since the vapor of (B2O3)2 evaporated from the diffusing source goes around the surface 3 and the diffusion is expedited, the diffusion distance is increased, and the surface concentration of the B diffused surface 3 is decreased. Thus, the low-concentration diffusion of B can be implemented, and the preliminary diffusion and end-up diffusion can be achieved in one process.

Title: Deflecting yoke
Inventor: INOUE TAKASHI
IPC: H01J29/76
Filed: 1992-05-28
Abstract: PURPOSE:To enable regular winding and to obtain deflecting yoke having high accuracy by forming slots on the inner surface of a core with a predetermined interval, and winding the coil so as to be divided into toroidal multi-layers in the slots. CONSTITUTION:Slots 1A are formed on the inner surface of a core 1 with a predetermined interval, and a coil is divided into multi-layers for winding so that the electric wires adjacent to each other are not overlapped. Consequently, deviation of the coil is eliminated to enable the arrangement of the vertical deflecting coil. Since the number of turns of a coil in one layer inside a slot is divided into multi-layers, the total layer quantity is reduced. Arrangement of the coil is thereby enabled, and the deterioration of the characteristic of a deflecting yoke due to the deviation of the coil is reduced to obtain a deflecting yoke having a high accuracy.

Inventor: DOBASHI KENJI
IPC: H04N3/18
Filed: 1994-06-20
Abstract: PURPOSE:To prevent deterioration in the image quality due to ununiformed shape of picture elements by controlling a drive voltage applied to a line cathode being a beam source generating an electron beam and giving corresponding adjustment data to a memory so as to eliminate the dispersion in a beam spot to be caused. CONSTITUTION:A counter 102a uses a clock 101a being a vertical synchronizing signal as an initializing signal and counts number of clocks 101b being 11H periodic signals till another clock 101a is received again. Then a counter 102b counts number of horizontal synchronizing signal clocks 101c by using the clock 101b as an initializing signal. A memory 103 receiving the count by the counter 102a as a high-order address and the count by the counter 102b as a low-order address provides an output of an adjustment value corresponding to a scanning line. The adjustment value is given to a D/A converter 104, from which an analog signal is given to an amplifier 105 and then the voltage of the analog signal is amplified to a degree to control a drive voltage of the line cathode. Thus, a vertical diameter of a beam spot is controlled by giving the adjustment address data to the memory.
