Title: Tape feed controller
Inventor: TSUCHIYAMA YOSHIRO
IPC: G11B15/467
Filed: 1988-06-17
Abstract: PURPOSE:To satisfactorily shorten the interruption processing time by decelerating the drive of a motor in the case it is detected with measurement of the FG pulse cycle that the tape speed is controller to a higher level as the shortage of the arithmetic processing time is increased. CONSTITUTION:A capstan motor 32 is prepared and the rotation detecting pulse (FG pulse) received from a rotation detector (frequency generator) 34 is inputted to a microcomputer 30. The microcomputer 30 outputs a control command of the motor 32 to a motor drive circuit 31 based on a command given from a system control circuit 33. In the case such a high speed that causes the shortage of the arithmetic processing time is detected by the speed information given from a speed detecting means 34, the multiplying process of the FG pulse is stopped and the filter arithmetic is omitted. Then a motor control command proportional to the speed error information or a deceleration command for a fixed degree is outputted to the circuit 31. The speed control is performs so as to perform the filter arithmetic again when the motor 32 is decelerated down to an arithmetic process enable state. As a result, the interruption processing time is extremely shortened.

Title: Electrode parts of electron gun
Inventor: NAKANO TOMOMOTO
IPC: H01J9/18
Filed: 1989-06-13
Abstract: PURPOSE:To prevent the withstand voltage property of a cathode ray tube from being deteriorated and the generating voltage of stray emission from being lowered by forming from a material harder than that of a spacer at least those faces of electrode parts which are forced to abut against the spacer. CONSTITUTION:A thin film 11 of hard material stuck to those faces of electrode parts 8, 9 which are forced to abut against a spacer 10 is e.g. a titanium thin film stuck thereto by vacuum deposition. The titanium thin film 11 is harder than a stainless steel plate that forms the spacer 10, and so its surface will not have a flaw even if the spacer 10 is pulled out after beading. The withstand voltage of a cathode ray tube using this electron gun and the generating voltage of stray emission are thereby enhanced.

Title: Device for generating and propagating surface acoustic wave
Inventor: INOUE NAOHISA
IPC: G02F1/11
Filed: 1985-07-11
Abstract: PURPOSE:To obtain a high deflection efficiency by forming a waveguide part having the widest width at a position near an inter-digital transducer (IDT) and narrowing its width gradually in a surface acoustic wave (SAW) transmitting direction on a surface acoustic wave (SAW) waveguide. CONSTITUTION:Even if the electrode interdigital length of the IDT 13 is extended and a wide SAW is generated, the wide SAW is shut in the waveguide part and gradually narrowed in accordance with its transmission because the SAW waveguide 121 has the part having the widest width at the position near the IDT 13 and narrowed gradually in the SAW transmission direction. Since the power of the SAW is concentrated into a narrow width in the transmitting process of the waveguide part of which width is gradually narrowed, a large change of a refractive index is obtained. Since the SAW transmitted through the waveguide 21 is projected from the end part of the narrow waveguide part, a practically equivalent effect to the generation of the SAW from the IDT 13 having a short electrode crossing length is obtained. Consequently, a wide SAW expanding angle is obtained and the deflection efficiency is improved.

Title: Phase locked loop circuit
Inventor: YABUKI HIROYUKI
IPC: H03L7/10
Filed: 1988-06-20
Abstract: PURPOSE:To initially match the phase of a frequency synthesizer and to pull in a frequency at high-speed by supplying reset signals to a phase comparator input terminal and a condition holding terminal at the time of activating. CONSTITUTION:A reset signal PS is supplied to the inputs of respective gates of input gates 10 and 11 and condition holding gates 12 and 13 of a phase comparator. When an activating signal PS signal is made into '0' level, the outputs of respective gates 10, 11, 12 and 13 are compulsorily made into one output. Since the input signals of condition holding gates 14 and 15 are also decided at '1' level, the outputs are decided to '0' level. As a result, while the PS signal is in a '0' level condition, oRoV outputs are both determined at '0' level. Thereafter, by making the PS signal into 1 level, the oR and oV outputs are made into ordinary actions of the phase comparator decided by the states of an FR and an FV.

Title: Picture processing method and picture processor
Inventor: YAMAGATA SHIGEO
IPC: G06T5/00
Filed: 1998-06-01
Abstract: PROBLEM TO BE SOLVED: To provide a picture processing method and a picture processor, which improve the reproducibility of a half tone character thin line in a pseudo half tone processing using a dither method through the use a threshold matrix. SOLUTION: It is detected whether an input picture signal belongs to a character thin line area or not based on the edge quantity of the input picture signal in a character detection part 3. When it is detected to belong to the character thin line area, the threshold of a dither matrix is changed to a smaller one in an output conversion part 6 and a pseudo half tone processing is executed on the input picture signal. Then, the reproducibility of a half tone character thin output picture can be improved by changing the dither threshold based on the characteristic of the input picture signal. Especially when the character area is detected, or the area is detected to have large edge quantity, the dither threshold is dropped. Thus, the effect of edge emphasis is obtained and the reproducibility of a half tone character can be improved.
