Title: Pressure swing two-tower type gas separation apparatus
Inventor: KAI NORICHIKA
IPC: B01D53/04
Filed: 1989-03-06
Abstract: PURPOSE:To omit the arrangement of a purging fan or blower by supplying purge gas from a surge tank to a treatment gas line on the upstream side of the blower of said line and introducing the same into an adsorbing tower by said blower. CONSTITUTION:Two adsorbing towers 1a, 1b are connected to a treatment gas line 1 equipped with a blower 2 in parallel and a bellows type surge tank 7 receiving separated gas is connected to the adsorbing towers 1a, 1b. A purge gas line 10 is connected to the treatment gas line 1 from the bellows type surge tank 7 on the upstream side of the blower 2. That is, by forming the surge tank into a bellows type structure, gas can be separated in a dry surge tank and the post-treatment of the separated gas in a dehumidifier can be made unnecessary. Since purge gas is supplied to the treatment gas line 1 from the surge tank on the upstream side of the blower to be introduced into the adsorbing towers by said blower, the installing of a purging fan or blower can be omitted.

Title: Manufacture of laminated iron core
Inventor: HORIUCHI MITSUYOSHI
IPC: H01F41/02
Filed: 1983-03-29
Abstract: PURPOSE:To easily obtain a laminated iron core using amorphous magnetic alloy thin plate by forming a frame like a picture frame by bending at a right angle the areas corresponding to the corners of iron core of a belt shaped amorphous magnetic alloy thin plate and continuously laminating such frames. CONSTITUTION:The iron core blocks 11-14 are formed by continuously bending the four corners of amorphous magnetic alloy thin plate 15 with a press. Next, distortion is eliminated by executing annealing process to the blocks 11-14. Since the iron core as a whole can be divided into the blocks 11-14 in the laminating direction and can be annealed, distribution of temperature of iron core as a whole can be uniformed during the annealing process. The blocks 11- 14 are impregnated with resin such as epoxy resin and are integrated. Moreover, the blocks 11-14 are combined and tightened by tightening bolts. Thereby, it is no longer necessary to cut the hard and brittle thin plates 15 with a cutter and the iron core blocks can be formed easily and continuously during the bending process.

Title: Electrophotographic recording paper
Inventor: HIRANO MITSUYOSHI
IPC: D21H21/28
Filed: 1995-03-13
Abstract: PURPOSE: To prevent recording paper from yellowing while maintaining yellow color reproducibility by setting a spectral reflection factor to a specific value or more and restricting a difference of a minimum value for the spectral reflection factor between on a short wavelength side and a long wavelength side to a specific range. CONSTITUTION: In spectral reflection factors, a spectral reflection factor for a wavelength of 380-780nm is 85% or more, while a difference between a minimum value R1 for a spectral reflection factor for a wavelength of 400-44nm and a minimum value R2 for a spectral reflection factor for a wavelength of 580-620nm ranges from -5% to +5%. Manufacture is carried out while the spectral reflection factor characteristic is satisfied by regulating a quantity of dye to be added. In concrete, a difference R1 -R2 in spectral reflection factor minimum values is set within the predetermined range while darkening of recording paper due to reduction in the whole spectral reflection factor is prevented by reducing an adding quantity of a blueing dye in comparison with an ordinary formula, and this is a preferable method.  In this way, high whiteness can be provided, and especially, yellow color reproducibility is improved when the paper is used for full color image forming.

Filed: 1989-03-06
Abstract: PURPOSE:To improve the label production efficiency by stopping the label production process with reception of a temporary stop command and at the same time outputting the message data from a host computer. CONSTITUTION:When a temporary stop command is received from a host computer 11 at continuation of a label production process with no occurrence of errors, an output port 21 is controlled and the label production process is immediately stopped. Then a message command C8 is sent from the computer 11 and therefore a CPU 13 controls an external device interface 20 to output a received message to a liquid crystal display 19. Then another label is produced again when another command is sent from the computer 11. As a result, the label production process can be controlled by the computer 11 even after the label production process is started. At the same time, the computer 11 can quickly has communication with a label printer 10. Thus the label production efficiency is improved.

Abstract: PURPOSE:To enable the high-speed response of a document communication by composing a document of document components and a communication procedure control part, allowing a tansmission terminal to transmit the document components according to the communicating procedure, and allowing a receiving terminal to recompose the communicating procedure control part. CONSTITUTION:Even the communicating procedure is added to a document construction as one document component in the form of the communication procedure control part.

In the receiving terminal, the communication procedure control part is recomposed based on the sequence of the received document component units, and the communicating of the whole document is executed. Consequently, first, character information is sent, it is displayed on a picture, thereafter, a voice is sent, and image information can be communicated while the contents of the character information are explained by a voice output. Thus, by processing the communication and display or the communication and accumulation in a pipeline way, the response time can be speeded up.

Abstract: PURPOSE:To improve the recognition rate in a short discrimination time even for mixed characters by using a weighting direction exponential histogram and a difference degree calculating method such as an artificial Maharanobis' distance/ artificial Bayes discriminating equation or the like to recognize characters. CONSTITUTION:A quantizing device 12 converts a multilevel pattern to a binary pattern and applies it to a CPU13. This pattern is stored temporarily from the CPU13 into a memory 14, and recognition processing such as character feature extraction, difference degree calculation, or the like are performed, and recognition results are outputted to an output device 15. A filter having a coefficient of weight is used for the character pattern to obtain a feature vector (weighting direction exponential histogram). Distances between preliminarily generated and stored standard patterns of respective character types and a character to be recognized are calculated. In an equation obtaining the Maharanobis' distance, inherent values of respective axes are used up to the K axis but inherent values are kept constant with respect to the (K+1) axis and following axes to calculate a degree of difference.

Title: Image forming device
Inventor: OKAZAKI AKITAKA
IPC: G03G15/00
Filed: 1996-03-11
Abstract: PROBLEM TO BE SOLVED: To simplify the constitution of a fixing unit. SOLUTION: An upper fixing unit 71 is simply coupled to a lower fixing unit 72 and a front surface part 4b being one part of an upper housing 14 is made to intervene in the middle of the turning allowable range θmax of the unit 71. As the result, when a cover 3 is opened, the Unit 71 is not turned to the miximum within the range θmax but it abuts on the front surface part 4b in the middle. That means, the turning action of the unit 71 is restricted within a prescribed range θTH. Thus, the fixing unit can be simplified in comparison with a case that it is provided with a spring member and the like. Besides, since the turning action of the unit 71 is regulated by the upper housing 4, the fatigue of a supporting point part being the center of the turning action of the unit 71 can be reduced.
