Title: Pseudo-random number generator
Inventor: KUROSAWA KAORU
IPC: G06F7/58
Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To obtain good random number characteristics by assuring equal frequency characteristics of output by performing an exclusive OR operation between at least one register value of a linear feedback shift register and a nonlinear transformation value of the remaining register values. SOLUTION: A nonlinear transformation function circuit 35 is connected with the linear feedback shift register 33 with L stages to generate an (m) system. In addition, an exclusive OR operation circuit 39 is connected between the nonlinear transformation function circuit 35 and an output terminal 37. Output of at least one stage 33a of the linear feedback shift register 33 with L stages is connected with the other input of the exclusive OR operation circuit 39. Since the linear feedback shift register 33 has a cycle of 2L-1, when L is sufficiently large, kinds of appearance probability of 1, 0 of output in a nonlinear filter generator with this structure are regarded as equal. Therefore, the pseudo-random number generator with good random number characteristics in which kinds of appearance of 1, 0 are in equal frequency is obtained.

Title: Elastic memory circuit
Inventor: CHIKU ISAO
IPC: G06F5/06
Filed: 1991-10-16
Abstract: PURPOSE:To perform a correct clock switching operation even if the writing timing and the reading timing are overlapping with each other. CONSTITUTION:A write signal generating circuit 22 produces the multiphase pulses WC1-WCn based on a write clock WCLK. The write date WDTA are stored in a storage part in a serial/parallel converter circuit 23 and then outputted with use of the pulses WC1-WCn. Meanwhile a read signal generating circuit 25 produces the multiphase pulses RC1-RCn based on a read clock RCLK and then latches the serial/parallel conversion output into a flip-flop 26 with use of the pulses RC1-RCn. Then a parallel/serial converter circuit 28 reads successively the data WDTA synchronously with the clocks of the receiver side and inputs them to a multiplexing device 13 of the receiver side in a bit serial way. Under such conditions, a phase comparator 27 compares the 1st and 2nd pulses WC1 and RC1 with each other and shifts the phase of the pulse RC1 when both purses are overlapping with each other. So that the pulses WC1 and RC1 are never overlapping with each other.

Title: Fd ion source
Inventor: TAMURA ATSUSHI
IPC: H01J27/26
Filed: 1989-10-13
Abstract: PURPOSE:To increase electric power supplied to an emitter in proportion to time by using an emitter heating circuit as a constant electric power control circuit, and applying a reference voltage variable in proportion to the time from a function generator. CONSTITUTION:A differential amplifier 9 calculates voltages at both ends of an emitter 2. An electric power detecting circuit 10 calculates an electric power supplied to the emitter 2 on the basis of the product of the voltage signal of the differential amplifier 9 multiplied by the current signal of another differential amplifier 6. A comparing circuit 7 compares the signal of the electric power detecting circuit 10 with the reference signal of a function generator 8, to control a current in such a manner as to obtain the constant electric power supplied to the emitter 2. The electric power supplied to the emitter 2 is changed linearly according to a change in a reference voltage from the function generator 8 in proportion to a time. Therefore, the temperature gradient of the emitter 2 can be maintained constant irrespectively of the time so that the temperature cannot exert any adverse effect on the emission time of an ion.

Title: Method and device for applying coating liquid
Inventor: SANARI TAKUYA
IPC: B05C11/08
Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To provide a method for applying a coating liquid wherein switching rotational direction enlarges difference in the number of revolution while the consumption of the coating liquid is reduced. SOLUTION: The number of revolution of a substrate is changed before the coating liquid supplied to the substrate is spread by a centrifugal force to cover the entire surface, so that the time required for coating is shortened and a coat is formed with less coating liquid. Here, the rotational direction of the substrate is switched from a forward revolution R1 to a reverse revolution R2. The difference in the number of revolution is enlarged within such a range as affected by no turbulence by reversing rotational direction, with the consumption of coating liquid further reduced.

Filed: 1987-10-26
Abstract: PURPOSE:To enable easy detection of an abnormal condition both before a printing operation and during the printing operation, by performing the detection while passing a discrimination bit signal with a small number of bits in a data line of a shift register. CONSTITUTION:When a discrimination bit signal 52a is not transmitted from an output terminal of a shift register 21 or is changed due to a fault such as breaking of wire in a part of a recording head such as the shift register 21, an error signal is outputted through a gate circuit 36 because two signals do not coincide with each other. In this case, an error signal instead of an ON signal is outputted from an LED element-driving circuit 4 to a control panel 6 or the like, thereby informing the user of the condition. When the discrimination bit signal 52a transmitted from the output terminal of the shift register or is changed due to breaking of wire or the like in the head during a printing operation, an error signal is outputted from the gate circuit 36. In this case, a driving power supply 5 is turned OFF, the printing operation is stopped, and an error signal is outputted to the control panel 6 or the like, thereby informing the user of the condition.

Abstract: PURPOSE:To improve the resolution by arranging a light receiving means such as a photo sensor at the outside of an optical path of a television camera so as to avoid interruption of an optical path. CONSTITUTION:A picture outputted from an output face 9 of an image intensifier I.I. is picked up by a TV camera optical system 12 via an optical path 5. Then a photosensor 11 is installed at an outside of the optical path 5 to measure a luminous quantity outputted from the output face 9 of the I.I. In this case, since the output face 9 of the image intensifier I.I. is almost a 100% complete diffusion face, the light outputted from the output face 9 is surely made incident in the photo sensor 11. That is, since no light shield is in existence in the optical path 5, the luminous quantity is not decreased and the resolution of an X-ray diagnostic picture is improved. Furthermore, a PMT (photo multiplier tube) or an optical semiconductor element or the like is used for the photo sensor 11 and especially a photo diode is small and effective.
