Title: Adjusting method of color purity of color picture tube
Inventor: TOKUDA ISAMU
IPC: H01J9/44
Filed: 1987-07-01
Abstract: PURPOSE:To make it possible to adjust the color purity of a picture tube accurately and quickly by arranging respective pairs of coils on both up and down, and left and right sides of the picture tube respectively so as to deflect electron beams by the current in respective coil pairs. CONSTITUTION:A pair of horizontal deflection coils 2 and a pair of vertical deflection coils 3 are arranged on the up and the down side and the left and the right side of a picture tube 1 respectively. At first a current is flowed in the coil 2, and the electron beam is deflected in transversal direction by the magnetic field induced by the said current, and the position of the beam spot 5 in vertical direction is corrected exactly with a purity magnet of a convergence device with reference to the shape of the shadow of a phosphor dot 6. Then the current in the coil 2 is cut off and a current is flowed in the coil 3 to deflect the beam in vertical direction, and the position of the beam spot in horizontal direction is corrected similarly. Thereby the beam spot 5 can be moved to any position required. Further the position of the beam spot 5 can be adjusted by the currents in the coils 2 and 3 so as that the distance between the centers of the phosphor dot 6 and the beam spot 5 becomes zero.

Title: Liquid metal ion source
Inventor: KATOU TAKAO
IPC: H01L21/302
Filed: 1983-09-10
Abstract: PURPOSE:To lengthen a life of a liquid metal ion source loaded with a liquid metal having strong reaction or a liquid metal having a high melting point by using an emitter metal wire rod on whose surface a metal carbide layer is formed. CONSTITUTION:Firstly, two tantalum wires 1 and 5 are spot-welded with a hair pin 3 of a tantalum wire while forming a needle by making the tip of the tantalum wire 1 into a needle shape by electrolytic polishing. Secondly, by performing washing and shaping as well as a carbonizing reaction, a carbonized tantalum layer is formed on the surface of the tantalum emitter metal wire rod, while the needle tip part subject to the severest wear becomes a carbonized tantalum single crystal. This is loaded with the liquid metal 4 while being made into an ion source. As a molding process is performed to the emitter metal wire rod before carbonization, its shape can be freely selected. Further, a single crystal carbide of good quality can be formed at the needle tip part subject to the severest wear.

Filed: 1982-09-24
Abstract: PURPOSE:To eliminate a mistake of calculation when the prescribed number of instructions are repeated, by comparing the storage value of a loop circuit setting register with the count value of a counter circuit CNT of a loop circuit which executes repetitively.

When a comparator CMP obtains the coincidence between the count output Cn and the output ln' given from the register LNR, a coincidence signal eq is delivered. While an excess signal gt is delivered when the output Cn exceeds the output ln' and then supplied to an ROM within the counter PC via a selecting circuit SEL and an FF circuit.

Title: For encoding and decoding circuit
Inventor: KISHIMOTO KAZUO
IPC: H04B14/04
Filed: 1986-07-14
Abstract: PURPOSE:To attain voice transmission while an operating band is compressed by using a voltage-frequency conversion/frequency-voltage conversion means in applying encoding/decoding. CONSTITUTION:When a voice signal S11 is inputted, level adjustment is applied by an input level adjusting circuit 1, the signal is converted by a voltage- frequency converter 2 and outputted as a signal 12A. The maximum frequency in this state is 23.8kHz normally. Then the signal S12A is binarized by a digitizing circuit 3, from which a binary-coding signal S12B is obtained. Furthermore, the signal S12B is outputted at a sample circuit 14 as an encoded voice signal S14A by using a timing signal S13A from a transmission clock generating circuit 15. Since the frequency of the signal S13A requires twice or over the frequency of the signal S12A in this case, the frequency is 47.6kHz. Thus, the operating band compression is realized.
