Title: Image forming device
Inventor: YUNAMOCHI TAKAYASU
IPC: G03G15/14
Filed: 1989-11-13
Abstract: PURPOSE:To always perform stable transfer without depending on environment by providing a current limitation means in destaticizing means adjacently arranged on the downstream side in the transfer material traveling direction of a transfer means. CONSTITUTION:The current limitation circuit C is connected to a destaticizing needle 22a. In the case of performing destaticization by the needle 22a, it is sufficient to set a current Il which flows in a grounding direction at 2muA to the maximum in order to destaticize the charge of a transfer paper P. Then, faulty separation or the splashing of toner is not caused even under the environment of low humidity. In such a case, the circuit C is made a 2muA constant- current circuit. When the resistance 15B of the transfer paper gets small under the environment of high humidity, the current which flows in a direction shown by an arrow (b) is limited because of the existence of the circuit C and a voltage at the contact point N of the transfer paper P with the transfer roller 5 is not lowered, thereby preventing the faulty transfer from occurring.

Abstract: PURPOSE:To prevent water from leaking out of a jet slot and improve the usage of the title iron by generating the output of steam generating signal from a setting means with a control means, and by feed-working a water feeding means only when a temperature from a temperature detecting means is a normal or higher temperature. CONSTITUTION:A control means A is composed of a temperature detecting circuit 2 and a signal processing circuit 3. In other words, when by the control means A, it is discriminated that the base temperature of an iron is a normal of higher temperature in the temperature detecting circuit 2, and a reversing switch 6 is set to generate steam, then the output of signal for permitting current to flow to a solenoid 5 for feeding or stopping water to a carbureter chamber is generated. When by the temperature detecting circuit 2, it is discriminated that the base temperature of the iron is of a normal or lower value, or when the reversing switch 6 is set to stop the steam even if the base temperature is of the normal or higher value, then the output of signal for interrupting current permitted to flow to the solenoid 5 is generated from the signal processing circuit 3. As a result, when the steam is set at the beginning and a temperature reaches the normal temperature, then the steam is generated, and steam generating operation is not required to be continuously performed, and ironing can be prevented form being performed in a state that the steam is not generated, and the usage of the iron can be improved.

Title: Recording paper feeder for printer
Inventor: KOMURO KIYOTO
IPC: B41J15/16
Filed: 1990-10-30
Abstract: PURPOSE:To obtain a recording paper feeder for a printer capable of recording characters even on the trailing end of recording paper with high accuracy without stains d recording paper by changing over the magnitude of a pressing force of a press roller in a plurality of steps during recording. CONSTITUTION:When reaching a gate roller 21 serving as a first feed part, recording paper S supplied from a paper supply part 10 is fed at approximately the same speed as the peripheral speed of the gate roller 21. When the leading end of the recording paper S reaches the position of a recording head 83, a photosensor detects the leading end of the recording paper S and printing is started on a predetermined position. The recording head 83 moves on the paper surface in the width direction of the paper. The paper is fed at a predetermined pitch for every line-printing of the recording head 83, and printing is conducted on the recording paper S. Before the trailing end of the recording paper S is separated from the gate roller 21, the recording paper S is pinched between a paper presser roller 37 and a follower roller 22. At this second feed part, the recording paper S is fed at the predetermined pitch after being separated from the gate roller 21. In this manner, recording can be made from the top of the recording paper S to the bottom thereof.

Title: Image conversion method and image encoding method
Inventor: BUN CHUN SEN
IPC: H04N19/00
Filed: 1996-11-06
Abstract: PROBLEM TO BE SOLVED: To use a conventional 8-bit encoding algorithm/device and a fixed/ variable length table that is necessary for the encoding by converting an N-bit image. SOLUTION: An object image having N bits per sample is inputted to a converter 712 via an input terminal 701, and a converted image is generated and inputted to a motion detector 714. At the same time, the past reproduced images stored in a frame memory 713 are also inputted to the detector 714 as the reference images. A motion vector is calculated to give a minimum estimation signal to the object image and then sent to a motion compensator 715 to generate an estimated image from the reference images. The motion vector is also sent to a variable length encoder 711 and converted into a variable length code. This code is outputted to an output terminal 706 together with the information including the motion vector. A 1st adder 702 calculates the difference between the object and estimated images. This difference is compressed by an encoder 703 and expanded by a decoder 707 and then stored in the memory 713. Thus, a luminance image of the large bit length can be effectively encoded and decoded by a conventional device owing to the conversion of an N-bit object image.

Title: Exhaust gas cleaning catalyst and its manufacturing method
Inventor: ISHIKAWA MICHIO
IPC: B01J23/62
Filed: 1999-10-15
Abstract: PROBLEM TO BE SOLVED: To suppress the sulfur poisoning of an exhaust gas cleaning catalyst of an NOx occluding and reducing type and to improve the cleaning performance after an endurance test. SOLUTION: A sulfur poisoning preventive layer 3 formed of the oxide or carbonate of a metal with its sulfate sparingly soluble or insoluble in water is formed on the catalyst carrying layer 2 of the catalyst of an NOx occluding and reducing type. Since the sulfate of the metal constituting the layer 3 is insoluble or sparingly soluble in water, the sulfate is hardly eluted into the moisture contained in the exhaust gas. Accordingly, the elution and diffusion of the sulfate into the layer 2 are prevented, and the sulfur poisoning of an NOx occluding material held in the layer 2 is strictly inhibited.

Title: Charging control system in solar generating device
Inventor: UMEZAWA YASUHIKO
IPC: G05F1/67
Filed: 1985-12-27
Abstract: PURPOSE:To obtain a charging device high in working efficiency by using a sun tracking device to obtain the maximum voltage from a solar voltage for charging in case the terminal voltage of an accumulator is set at a low level. CONSTITUTION:When the terminal voltage VB of an accumulator 3 is less than the terminal voltage obtained in a full charge mode, a switch control circuit 9 sets a changeover switch 8 at the side of a maximum power point tracking controller 6. Thus the controller 6 controls a DC/DC converter 5 to control both the output voltage and the output current of a solar battery 1. As a result, the battery 1 is operated at the maximum power point regardless of the charging state of the accumulator 3. The voltage VB of the accumulator 3 rises up as the accumulator 3 is charged. Then the circuit 9 sets the switch 8 at the side of a current controller 7 when the accumulator 3 is approximately set in its full charge mode.

IPC: H04N1/405
Filed: 1989-11-13
Abstract: PURPOSE:To improve the resolution of characters by applying video image separation to a fully white or black level part with less total sum of difference of density so as to compensate the fully white and black level and to apply excellent gradation expression and extracting a contour over a wide range so long as the total sum is applicable. CONSTITUTION:When the total sum L being a difference of density is less and a dither threshold T is small, a binarizing threshold level U is set by using a fixed threshold level B1 to specify the white density and a coefficient K1 for normalization is set by equation I to apply a fully white level. When the L is small and the T is large, the threshold level U is set according to equation 2 by using a fixed threshold level B2 to specify the black density and a coefficient K2 for normalization to compensate the fully black level. When the L is large and the T is less than the value specified in relation to the L, the U is set according to equation 3 by using a fixed threshold level B3 and a coefficient K3 for normalization to preserve the contour of a character or the like. Thus, excellent gradation expression is implemented and the resolution of the character is improved.
