IPC: D03D41/00
Filed: 1990-05-18
Abstract: PURPOSE:To prevent the insufficient warp opening by independently controlling the tension of a part of warps crossing with small number of wefts and that of the remaining warps crossing with large number of wefts in the course of delivering a warp from a warp beam. CONSTITUTION:The fabric is produced by delivering a warp from single warp beam. In the above process, a part of warps crossing with small number of wefts and the remaining part of warps crossing with large number of wefts are wound round on respective exclusive tension rolls. The above warps crossing with small number of wefts are actively loosened during the period from at least the closure of the warp to the start of beating and the warp tension is set to a level lower than the tension of a stage other than the above period. The warp crossing with small number of warps and having a loosening tendency is transferred toward the cloth fell in contact with wefts to prevent the insufficient opening of the warps.

Title: Sheet feed device
Inventor: KOYAMA TAKESHI
IPC: B41J15/16
Filed: 1991-05-30
Abstract: PURPOSE:To provide a sheet feed device capable of preventing a printing position from becoming offset by making the position of a sheet transported by a transport part stable rapidly. CONSTITUTION:A sheet feed motor 16 is rotated normally by an extra rotary angle by  n pulse using a drive device 20 and this sheet feed motor 16 is rotated backward by  n pulse in a serial printer. Subsequently, a sheet is pulled to the downstream side of a printing head 5 by a transport part so that the sheet is fed by a specified length. Then the sheet is returned to a printing head 5 side by reversing the transport part and the tension of the sheet is eased instantaneously when the transport part stops. Thus the sheet is printed in a state where it is stabilized rapidly and thereby a printing position is prevented from becoming different on both sides of the sheet.

Title: Thermal head preheater
Inventor: YAMAJI HIDEYUKI
IPC: B41J2/38
Filed: 1989-05-19
Abstract: PURPOSE:To conduct printing immediately even if the temperature of a thermal head is lower than a printing guarantee temperature by outputting a detection temperature of a thermister to a preheat control circuit through a preheat judging means. CONSTITUTION:A detection signal of a thermister 122 is supplied to a preheat judging circuit 124, and the preheat judging circuit 124 judges whether a detection temperature T is lower than a minimum printing guarantee temperature T0. If it is lower than T0, a preheat signal is supplied to a preheat control circuit 16 and a printing circuit 18. In the case of T>=T0, i.e., when the supply of a preheat signal is absent, output terminals ENABLE, LATCH, and SDATA of the preheat control circuit 16 are in a high impedance state. In this case, a normal printing is conducted by the printing circuit 18. On the other hand, if a detection temperature T has a relation T<T0, correspondingly to a preheat signal from the preheat judging circuit 124, output terminals ENABLE, LATCH, and SDATA of the printing circuit 18 come into a high impedance state. In this case, the preheat control of a thermal head 10 is conducted by the preheat control circuit 16.

Also, the unit 3 assignes the RAMs 5 and 6 to the RCs 1 and 2 and processes reception pulses before writing them to the RAM 4. In the processing, the unit 3 assignes the first bit, other bits and end of a message and the respective standby of mitigation time to the respective RCs 1 and 2 and processes them. Thus, the problems of the interference between the signals (a) and (b) and the identification of the RCs 1 and 2 are solved.

Title: Transformer
Inventor: TAKAMIYA TAKAOKI
IPC: H01F27/28
Filed: 1985-06-12
Abstract: PURPOSE:To make it possible to transmit the electric power from the primary winding to the secondary winding faithfully without loss, by winding the primary and the secondary windings of transformer in a unitary body of a coil tube. CONSTITUTION:The conductor 1 is covered with the insulator 2, the conductor 3 and the insulator 4 in this order and forms the cable 5. The transformer 6 in which the cable 5 is wound in the form of a coil constitutes the primary winding and the secondary winding by the conductor 1 and the conductor 2, respectively. When a current flows through the conductor 1, the magnetic flux generates around the conductor 1 and it can not help crossing with the conductor 3, because it covers the conductor 1 through the insulator 2. Accordingly the magnetic flux produced by the primary winding contains little leakage flux. The magnetic flux which is produced by the conductor 1 and flows only in the insulator 2 also crosses with the conductor 3. Moreover, all the magnetic flux produced by the current flowing through the conductor 3 crosses with the conductor 1, so that the cause of leakage flux does not exist.

Abstract: PURPOSE:To enable an effective use of an expensive noble metal catalyst through the elongation of durability of the same by providing a combustion apparatus storing a catalyst having palladium as a main active component at the first-half stage side and storing a catalyst having platinum-rhodium alloy as a main active component at the second-half stage side with fuel, performing ignition of fuel mainly at the first-half stage side and combution of fuel at the second-half stage side. CONSTITUTION:A palladium catalyst is packed in the first-half stage side while a platinum-rhodium alloy catalyst in the second-half stage side, and natural gases containing methane are burned in contact with the air under normal pressure. Then, ignition of fuel is performed by palladium at the first half stage side, and the combustion of fuel ignited by the platinum-rhodium alloy is continued at high temperature at the second-half stage side because of high ignitability of palladium. In this method, although platinum which is apt to be converted into an oxide is contained as a catalytic component, it is free of sublimation due to oxidation because it exists in the form of an alloy with rhodium, so that prolanged use of a highly activated catalyst is realized.
