IPC: H01J23/40
Filed: 1988-08-23
Abstract: PURPOSE:To prevent an oscillation due to a leak high frequency power by arranging a dielectric between a high-frequency circuit part and a collector, and positioning the dielectric on a circumference having an average diameter 2 to 5 times as large as the electron beam passage hole of the collector part. CONSTITUTION:A dielectric 20 for preventing a leak high-frequency power is located between a high-frequency circuit part 2 and a collector part 4, and the position of the dielectric is taken on a circumference having a diameter 2 to 5 times as large as the electron beam passage hole 21 of a collector electrode 13 at the collector part 4. Consequently, much of high-frequency electric field is concentrated in the dielectric 20 for preventing a leak high-frequency power, and the electric field at an elec tron beam 19 becomes extremely small. According to the aforesaid construction, bonding becomes very small between the oscillation mode of a resonant cavity formed with a collector support body 11, a collector ceramic 12 and the collector electrode 13, and an electron beam 19. The leak high-frequency power through the collector ceramic 12, therefore, drops to such an extent as little influencing an oscillation signal adversely.

Title: Automatic preset device
Inventor: HAYASHI TAISUKE
IPC: H03J7/18
Filed: 1992-08-06
Abstract: PURPOSE:To provide an automatic preset device capable of reducing number of noise when preset is made. CONSTITUTION:A threshold level storage means (RAM) 48 stores plural threshold levels of reception intensity signals (electric field strength of reception frequency). A control means (CPU) 44 reads the threshold level from the threshold level storage means 48 and changes the threshold level from the maximum threshold level to a smaller level sequentially and applies scanning storage processing (scanning) to the threshold level. Thus, since the reception frequency with high electric field strength is preset stepwise, the opportunity of presetting noise with low electric field strength is reduced.

Title: Integratable differential amplifier
Inventor: KURAUDE BARE
IPC: H03F3/45
Filed: 1990-08-07
Abstract: PURPOSE: To reduce the in-phase amplification of the amplifier by adding the control FET(field-effect transistor) complementary to other FETs to every amplifier branch. CONSTITUTION: An amplifier branch has the control FET S12 and S22 which are complementary to the control FET S11 and S21 respectively. The FET S11 and S12 and the FET S21 and S22 form the CMOS inverters respectively, and these inverters are connected in series between the current source transistors TR Q11 and Q12 and the TR Q21 and Q22 respectively. For instance, when the TR Q11 and Q12 of a 1st amplifier branch become larger in regard to a common factor, the amplification factor that is led to an output terminal A from a positive input terminal E1 is increased without suffering any influence of the amplification factor that is led to the terminal A from a negative input terminal E2. As a result, the in-phase amplification is reduced for a differential amplifier.

Title: Data communication system
Inventor: ISHII MIE
Filed: 1984-10-09
Abstract: PURPOSE:To shorten the communication time by communicating data between a master station and slave stations with general IDs which designate plural object slave stations. CONSTITUTION:An ID setting and storage means consists of memory elements or dip switches, and general IDs with which the master station designates object slave stations and individual IDs are stored there. Since both of general IDs a1-an using a parameter X and individual IDs b1-bn using individual parameters are stored in slave stations A1-An, data can be transmitted to all slave stations A1-An at a time by the parameter X of general IDs a1-an if the same data is transmitted from a master station 7 to slave stations A1-An. In comparison with a conventional system, the time of one communica tion in this system is t-number of seconds and is 1/n of nxt-number of seconds in the conventional system. Thus, general IDs are provided besides individual IDs in plural slave stations to transmit data from the master station to all slave stations to transmit data from the master station to all slave stations in one data transmission in case of the same data.

Title: Servo system for magnetic disk
Inventor: MORIYA KAZUNORI
IPC: G11B5/596
Filed: 1985-09-24
Abstract: PURPOSE:To accurately position a magnetic head, by dividing the difference signal of the 1st and 2nd positional information obtained from servo information by the summed value of the 1st and 2nd positional information and positioning the magnetic head to an aimed track. CONSTITUTION:The difference signal of the 1st and 2nd positional information obtained from servo information is divided by the summed value of the 1st and 2nd positional information and a magnetic head is positioned to an aimed track by using the value thus obtained. Therefore, even when levels of the signals of the 1st and 2nd positional information read out from a disk are different from each other between the inner and outer peripheries of the disk, obtained values do not rely upon the track position of the disk, because the difference between the 1st and 2nd positional information is standardized with the sum of both information. Accordingly, accurate positional information of the magnetic head can be obtained regardless of the track position of the disk.

Title: Electrode etching solution of aluminum electrolytic capacitor
Inventor: SUGINO SATOSHI
IPC: H01G9/04
Filed: 1987-08-25
Abstract: PURPOSE:To reduce a cost of an etching solution and to control the solution economically by a method wherein new HCl is added to obtain a specific range of the effective HCl concentration and a working life of the etching solution is lengthened until the total HCl concentration reaches a specific value. CONSTITUTION:A drop in an etching magnification is not so related to a dissolved quantity of aluminum in an etching solution; the etching magnification drops remarkably when the effective HCl; concentration becomes ON. Accordingly, even when the dissolved quantity of aluminum is more than 10g/l, the etching magnification can be maintained if the effective HCl concentration is more than 0.1 N. If the effective HCl concentration is within 0.1N-1.3 N, the drop in the etching magnification is small. That is to say, if new hydrochloric acid is added continuously to obtain a range of 0.1N-1.3 N of the effective HCl concentration and the concentration is controlled, it is possible to nearly double the working life of the etching solution.

Title: Exhaust gas purging device of internal-combustion engine
Inventor: KATOU TAKASHI
IPC: F01N3/22
Filed: 1982-12-02
Abstract: PURPOSE:To improve purging of a large amount of unburnt gas, exhuasted when an atmospheric pressure therearound decreases, without using an expensive device, by a method wherein the air-fuel ratio of fuel-air mixture is maintained at a specified value, and a pressure sensitive switch is provided. CONSTITUTION:When an atmospheric pressure therearound is about a standard atmospheric pressure, a solenoid 67 is actuated and controlled by means of an output signal from a pulse generator 71 with 1-2HZ frequency, and secondary air is intermittently fed in an exhaust manifold 3 by a secondary air feed control valve 50. Since the air-fuel ratio of fuel-air mixture produced in a carbretter 2 is normally maintained at a specified value, the air-fuel ratio is vaired at 1- 2HZ frequency within a range of from + or -0.2 to + or -1.0 based on an approximately theoretical air-fuel ratio. Besides, the mean value thereof is maintained within a window W0, and thereby a high purging efficiency may be obtained through utilization of the oxygen holding function of a ternary monolith catalyst 5. When an atmospheric pressure decreases, a bellows 75 is expanded, a switch 76 is turned ON, the solenoid 67 is consecutively energized, secondary air continues to be fed, and this promotes the oxidizing reaction of unburnt HC, CO.
