Title: Frequency characteristic correction circuit
Inventor: UENO TOSHIAKI
IPC: H03K19/0952
Filed: 1989-05-19
Abstract: PURPOSE:To realize a stable operation from a low frequency without losing first speed performance by providing a means correcting the gain frequency characteristic caused at a low frequency region specific to a gallium arsenoid element and making the characteristic flat. CONSTITUTION:When a circuit 1 to be corrected consists of a passive circuit, assuming A(f) as a transmission characteristic of a circuit to be corrected 1 and H(f) as a transmission characteristic of a correction circuit 2, the transmission characteristic between the input and output is made flat by applying the correction as shown in the figure. That is, the correction circuit 2 having a characteristic making the gain at a low frequency region coincident with the gain of a high frequency region is connected to make the transmission characteristic between the input and output flat. Thus, the stable operation from a low frequency is realized without losing the high speed performance of an electronic circuit including the gallium arsenoid element.

Abstract: PROBLEM TO BE SOLVED: To reduce the transfer amount of white bit data that indicates blank space, by a method wherein addresses in a memory of bit-serial bit data excluding the white bit data that is contiguous exceeding a specified number are stored, and the bit data is stored in a memory based on the addresses stored. SOLUTION: The length of a header is written in a forefront part 16 of each of the headers, image data and character code classification in a data frame and a set mode such as overwriting mode, etc., are written in a control command part 17 next to the forefront part 16, the top address in the data frame is written in a data storage top address part 18 next to the control command part 17, and the length of the data frame is written in a tail part 19 of the header.

Abstract: PURPOSE:To obtain the impregnated cathode having a little amount of evaporation together with a stable quality by forming a gap while removing by the thickness of a few mum. an electron emissive substance located inside an empty hole and exposed on the cathode surface. CONSTITUTION:The high melting point metal powder such as tungsten powder is sintered into a desired cathode form for forming a cathode base 1 having porosity of 20-25% while being heated up to 1,600-1,700 deg.C after being coated with an electron emissive substance or the like formed in advance for being melted and impregnated. Thereafter, a surplus electron emissive substance attached to the cathode surface except the empty hole of the cathode base is removed by polishing.

Title: Multiplex image forming device
Inventor: HASEGAWA TAKASHI
IPC: G03G15/16
Filed: 1986-05-30
Abstract: PURPOSE:To prevent an offset development by constituting the titled device so that the charge of a transfer material carrying sheet immediately before being opposed to an image carrying body in which a transfer material is not carrying a toner image is more than the charge of a transfer material carrying sheet immediately before being opposed to the image carrying body in which the transfer material is carrying a toner image. CONSTITUTION:In case of the full color copy of an A4 size, a no-load rotation does not occur, therefore, the same sequence as the operation of an inside electrifier is available, but in case of the full color copy of an A3 size, the no-load rotation is executed, therefore, it is necessary to execute turn-off and turn-on as shown by a timing chart. That is to say, as soon as the transfer of yellow of the first color is started, the operation of the inside electrifier is turned off, and also, the operation is started when a photosensitive drum and a transfer drum pass through a nip in case of the no-load rotation of the tip of a transfer material. These turn-off and turn-on are repeated total three times in the same way. However, after the transfer of block of the fourth color, the transfer material is discharged immediately, therefore, these turn-off and turn-on operations are not required.

Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To operate a parameter, for which the range of values to be taken is wide, at high speed with high accuracy without depending on any floating point method. SOLUTION: The same number of bits in a mantissa part register 25 is set to a bit number register 14. When parameters (a), (b) and (c) are set to registers 11-13, the maximum value is found by a maximum value discriminator 15. A digit number computing element 16 sets the number of bits of the maximum value to a bit counter 17. Besides, the number of bits of the maximum value is compared with the fixed number of bits in the bit number register 14 and when the former number is more, its differential number (e) of bits (digits) is set to a digit number part register 18. Shifters 19-21 fetch the (a), (b) and (c) and sets a', b' and c', which are shifted to right just for the number (e) of digits, to mantissa part registers 22-24.  A sum-of-products operating part 10 fetches the mantissas a', b' and c' and operates the sum of products between input values such as coordinate values X and Y, for example, as prescribed. The operated result is shifted to left just for the number (e) of digits by a digit shift part 26.

Title: Digital demodulator for signal modulated by phase transition in plurality of statuses
Inventor: AREN ZAAREMUBOUITSUCHI
IPC: H04L27/233
Filed: 1991-05-29
Abstract: PURPOSE: To operate a demodulator at a clock speed equal to or lower than the transmission speed of a modulation code by quantizing components with individual quantization thresholds in a sampling and quantization circuit. CONSTITUTION: A signal S1 is applied to input terminals of plural stages of a first quantizer 10, and a signal S0 is applied to input terminals of plural stages of a second quantizer. Signals S1 and S0 are in-phase and orthogonal phase components of a modulated signal which are obtained by amplification, filtering, and substitution of the frequency of the modulated signal received by the demodulator. Signals S1 and S0 are sampled and quantized by sampling and quantization circuit 10, and a carrier restoration circuit 40 restores a carrier which demodulates the input signal. Since the circuit 10 quantizes components S1 and S0 with Na -1 individual quantization thresholds, the signal is demodulated at a clock speed equal to or lower than the transmission speed of the modulation code without using an external circuit. Na is the number of stages of amplification and quantization.

Title: Regeneration of adsorption device for refining helium gas

Filed: 1988-05-25
Abstract: PURPOSE:To recover an adsorption device for refining helium gas by regenerating an adsorbent with a heated regeneration gas introduced in the adsorption device and vacuum-discharging the heated regeneration gas as it is at a high temperature. CONSTITUTION:Two adsorption devices are provided on a refrigerator so that these are selectively used for continuous operation. If the regeneration of an adsorbent is performed on the second adsorption device 21, helium gas is released from the adsorption device 21 through a discharge pipe 34 to the atmosphere by opening a valve 25. Next, nitrogen gas heated at upto 250 deg.C, for instance, is introduced into the adsorption device 21 from the valve 26. If the adsorption device 21 is heated, this state is maintained for a fixed time and an impure gas adsorbed is purged and discharged together with the nitrogen gas. After this, the remaining nitrogen gas is vacuum-discharged using a vacuum pump 33 by opening a valve 24. At that time, the temperature of the adsorbent is high because the nitrogen gas remains heated. Therefore, the nitrogen gas is not absorbed to enable complete regeneration of the absorbent.
