Title: Preset memory
Inventor: WATANABE MOTOSHI
IPC: H03J5/02
Filed: 1993-03-31
Abstract: PURPOSE:To simplify operations by providing plural groups, which can store frequencies respectively transmitted by arbitrary broadcasting stations, at respective channels and applying identification codes by areas to the respective groups. CONSTITUTION:A memory means 20 is provided with the plural groups as the first group to which 'A' is applied as the area identification code to designate the area of Tokyo, for example, and the second group to which 'B' is applied as the area identification code to designate the area of Nagoya. A control means 10 detects the last frequency, namely, the frequency of radio under receiving at present and the receiving state. When the last frequency gets adverse, the other frequency stored in the other channel of the group, to which the last frequency belongs, is scanned and retrieved. When the frequency of the satisfactory receiving state is detected, the present channel is switched to the other channel where that frequency is stored. Thus, when the area is changed, it is enough only to select the group including the channel where the frequency suitable to the relevant area is stored.

Abstract: PURPOSE:To achieve a high resolution by constructing a phase-locked loop so that the phase difference between a position signal varying in the shape of a sine wave and an output signal of a sine wave oscillator provided separately is made zero, and by adopting the control amount of said loop as a position signal. CONSTITUTION:Outputs ealpha and ebeta from a position signal pickup are inputted together with outputs ealpha' and ebeta' of D/A converters 14a and 14b to an adder-subtracter 8 through multipliers 7a and 7b, and a voltage (e) (DELTAtheta) proportional to the phase difference DELTAtheta between them is inputted to a counter 11 through VCO9 and a direction discriminator 10. Then, a memory address of a storage circuit 13 is given through a latch circuit 12, and the data thereof are outputted to the circuits 14a and 14b. Thereby the voltages ealpha' and ebeta' of phases coinciding with the phases of the outputs ealpha and ebeta are outputted from the circuits 14a and 14b, and thus the control amount at that time, in other words, the data of the counter 11, can be made a rotational angle of a motor 1.

Title: Time axis conversion circuit for luminance signal
Inventor: NAGOYA TETSUO
IPC: H04N9/81
Filed: 1988-03-28
Abstract: PURPOSE:To attain time axis conversion of a Y signal with less memory capacity by using N+1 sets of line memories, writing the inputted Y signal to the N+1 sets of line memories sequentially for each 1H, reading them sequentially for each 1H at a lower speed than the write speed and dividing them into N channels. CONSTITUTION:An input selector 3 is switched for each 1H of a Y signal by a control circuit 2 to distribute the Y signal in the order of 4 5 6 4 ... to line memories 4, 5, 6 sequentially. Thus, the Y signal is written sequentially in the unit of 1H in the line memories 4, 5, 6. The content of the line memories 4, 5, 6 is read by a readout clock of a frequency fR in the relation of fR<fW before the write is applied next to expand the time axis. The Y signal read from the memories 4, 5, 6 is selected by output selectors 7, 8 alternately in the read order and shared into two channels. Three line memories are used in this way to obtain the Y signal of two channels whose time axis is expanded thereby reducing number of required line memories.

Abstract: PURPOSE:To simplify the assembling by forming a bevel gear to a peripheral plane of a varible condenser drum fitted to a variable condenser shaft and forming a spur gear to a peripheral side face to drive the variable condenser shaft and a pointer at the same time in turning a tuning knob. CONSTITUTION:In turning the tuning knob 8, the varible condenser shaft 4-1 is driven by meshing between the tuning shaft 6, the variable condenser drum 5 and the bevel gears 6-1, 5-1 and also the pointer 7 is slided by meshing between the variable condenser drum 5, the pointer 7 and the spur gears 5-2, 7-1. A variable condenser drum press contact rib 3-4 is provided to a dial chassis 3 so as not to cause a gap to the meshing part between the bevel gears 5-1, 6-1 thereby preventing the turning backlash between the turning shaft 6 and the variable condenser shaft 4-1. Since the variance in the height of the variable condenser 4 is large, the variance in the height of the variable condenser drum 5 is absorbed by connecting the bevel gear 5-1 being the engagement part of the variable condenser shaft 4-1 and the engagement part with the tuning shaft 6 with the thin rib 5-4 so as to utilize the elasticity of the resin of the variable condenser drum 5 itself.

Filed: 1984-04-13
Abstract: PURPOSE:To obtain an ion source whose operation is stabilized and which is minimally contaminated by applying voltage across a plate-like first electrode and a second electrode placed facing each other and installing a plural number of permanent magnets on the first electrode. CONSTITUTION:A magnetic field 18 parallel to a first electrode 13 is produced over the first electrode 13 by means of two facing permanent magnets 14 having different polarities. An electric field 19 perpendicular to the magnetic field 18 is produced by applying voltage across the first and the second electrodes 13 and 16. When ionized gas is introduced through a gas introduction inlet 20, molecules of the gas are ionized by bumping against rotating electrodes thereby producing plasma through electric discharge. Positive ions in the plasma are discharged through a beam hole 21 as ion beams 22. The first and the second electrodes 13 and 16 are prepared from carbon graphite, so that a polymer film hardly adheres to the electrodes 13 and 16 and stabilized operation of the ion source is achieved.
