Title: Dielectric filter
Inventor: TODA ATSUSHI
IPC: H01P1/212
Filed: 1995-03-08
Abstract: PURPOSE: To enhance the freedom of design in a resonance frequency and the degree of coupling between resonators and then to easily realize a desired filter characteristic. CONSTITUTION: Resonator holes 2a, 2b having a step difference section 21 are formed in a dielectric block 1, and a large inner diameter part formed to an opening side end face of each of the resonator holes 2a, 2b is formed nearly elliptically, and a small inner diameter part formed to a short-circuit side end face is formed circular, and the major axis direction of the large inner diameter part is formed in parallel with a broadwise direction of the dielectric block 1. Through the constitution above, since the self-capacitance and the mutual capacitance at the opening side end face are set larger, the resonance frequency is set lower and larger capacitive coupling is obtained for coupling between resonators.

Title: Picture memory
Inventor: HARA HIROYUKI
IPC: G06T1/00
Filed: 1989-02-28
Abstract: PURPOSE:To reduce the memory capacity and at the time to shorten the reading time by using an input means to perform a logical arithmetic operation between the picture information and the fixed information on a format, etc., and compressing the extracted variable information. CONSTITUTION:A CPU 21 inputted the picture information inputted via an input means via a bus 20 and controls each device based on a program stored in a ROM 22 and related to a picture process. A logical arithmetic circuit 26 performs a logical arithmetic operation between the input picture information and the fixed information on a format, etc., and extracts the variable information. This information is compressed by a compressing/expanding circuit 29 and stored in a RAM 23 via a control circuit and in relation to the fixed information. Thus the input picture information is directly compressed and can be stored in the RAM 23 of a small capacity. Furthermore just the variable information suffices for reading with expansion to the second and subsequent sheets. Then the picture reading time is shortened.

Title: Position detecting device
Inventor: TANIMOTO SHIYOUICHI
IPC: H01L21/30
Filed: 1983-03-24
Abstract: PURPOSE:To make positioning quick and to enhance gap accuracy, by scanning two luminous fluxes so as to cross marks provided on two plates, detecting the positions of the two plates in the direction of the gap at the first part, and detecting the position of the two plates in the direction of the scanning locus at the second part. CONSTITUTION:Alignment marks are scanned by spot light beams SPM and SPW. When the spot light beam SPM is aligned with the marks 10A and 10B, diffracted light beams are generated by the marks 10A and 10B. Photoelectric conversions 17 and 20 of the diffracted light beams from the alignment marks 10A and 10B and the diffracted light beam from an alignment mark 11 of a wafer W are performed. Clock numbers A, B and C are stored in a CPU 53 through amplifiers 100 and 101, detecting circuits 102 and 103, and an LT 109. The CPU 53 computes a deviation amount DELTAX of a mask M and the wafer W in the direction SL of a scanning locus. A stage is moved in the scanning direction X by the amount corresponding to DELTAX.

IPC: H01J31/12
Filed: 1984-03-14
Abstract: PURPOSE:To achieve static concentration of three beams on the surface of a shadow mask by shifting the centers of the openings of an electrode from those of the other electrode installed in the same channel. CONSTITUTION:A red, a green and a blue modulation signal are applied to modulation electrodes 45R, 45G and 45B respectively. The modulated beams are then focused by a beam-focusing electrode 46. At the same time, because the centers of the openings 46R and 46B of a beam-focusing and concentrating electrode 46 do not coincide with the centers of the modulation electrodes 45, the three beams are focused on the surface of a shadow mask 49. Horizontal deflection voltage in a form of sawteeth-like or staircase waves with the horizontal scanning frequency is applied to horizontal deflecting electrodes 48 so as to focus the three beams horizontally located at give intervals on the surface of the shadow mask 49 while deflecting them.

Filed: 1984-03-15
Abstract: PURPOSE:To hold invariably the correction amount of upper and lower pincushion distortion at a proper value by providing a frequency-voltage converting circuit which generates a voltage corresponding to a horizontal frequency and a control circuit which controls the amplitude of a saw-tooth wave of a horizontal period supplied to a modulating circuit, and controlling a horizontal parabolic wave which flows through a vertical deflecting coil to an invariably constant amplitude even when the horizontal frequency varies. CONSTITUTION:A horizontal synchronizing signal is inputted to an input terminal 1 and supplied to a horizontal deflecting circuit 2. A horizontal deflecting circuit drives the horizontal deflecting coil. The horizontal deflecting circuit 2 generates horizontal pulses, which are supplied to a saw-tooth wave generating circuit 9. A modulating circuit 6 imposes balanced modulation on the saw-tooth wave of a horizontal period generated by the saw-tooth wave generating circuit 9 by using a saw-tooth wave of a vertical period generated by a resistance 10. The output of the modulating circuit 6 is amplified by an amplifying circuit 7 to drive the primary winding of a pincushion transformer 8. Consequently, the current generated by superposing a horizontal parabolic wave upon the vertical saw-tooth wave as shown in a figure (b) flows through the vertical deflecting coil 5 to correct the upper and lower pincushion distortion.

IPC: H01J61/44
Filed: 1987-03-04
Abstract: PURPOSE:To reduce the measurement error by using a phosphor with the specific spectral emission characteristic. CONSTITUTION:A specific phosphor is used so that the radiation energy passing a bulb is increased by 5-17 times as the wavelength is increased by 5nm between the radiation wavelength of 295-310nm and the radiation energy becomes the maximum between 305-325nm, and the leading edge of the spectral distribution on the short wavelength side is made sufficiently sharp. One example of this phosphor is cerium-activated lanthanum phosphate, and the cerium activation quantity is set within the range of 0.05-0.4mol, preferably within the range of 0.1-0.3mol. The increasing rate of the radiation energy near 295-310nm becomes approximate to that of the solar rays by the absorption characteristic of the ultraviolet ray transmitting glass and the radiation energy characteristic of the phosphor. Accordingly, the abnormality deterioration or the like does not occur in the test, and the measurement error can be reduced correctly.

Abstract: PURPOSE:To automate the reconstitution of the system by implementing provision of an address number to each transmission unit and separation or coupling of transmission paths automatically in the case of extension, reduction or recombination of plural transmission units connecting to a loop transmission line. CONSTITUTION:For example, a transmission unit 1a is selected as a master unit and an address number of the master unit 1a is set as '#1'. Then a transmission control means 6a outputs information representing an address number '#2' to address transmission lines 5a-5n. A transmission control means 6b receives the address information sent from the master unit 1a and sets it as the address number '#2' of its own unit 1b. Then the transmission control means 6a outputs the information representing an address number '#3' to the address transmission lines 5a-5n, a transmission control means 6c of a transmission unit 1c receives the address information this time and sets the address number of its own unit 1c as '#3'. Thus, the transmission among all the units 1a-1n is attained.
