Abstract: PURPOSE:To obtain a flexible pipe for an endoscope which is not wrinkled during curving by putting blades via a release agent on the outside circumference of a flex formed by winding spirally a belt-like plate and adhering a sheath consisting of a synthetic resin via an adhesive agent to the outside circumference thereof. CONSTITUTION:The release agent 17 is coated on the outside circumference of the flex 14 formed by winding spirally a belt-like metallic plate and is dried and thereafter the blades 15 are put on the outside circumference of the flex 14 coated with the agent 17. The adhesive agent 8 is coated on the surface of the blades 15 and dried and thereafter the sheath 16 consisting of the synthetic resin is adhered to the outside circumference of the blades 15 on which the agent 18 is coated, by which the intended flexible pipe for the endoscope is obtd. The layer 17 is interposed between the flex 14 and the blade 15 of the resulted flexible pipe and therefore the flex 14 and the blades 15 move respectively independently during curving thus the flexible pipe exhibits good resilience to curving without receiving undue stress.

Title: Recording head and recorder using the same recording head
Inventor: UCHIKATA YOSHIRO
IPC: B41J2/335
Filed: 1989-04-10
Abstract: PURPOSE:To enable heat from a recording head to be faithfully transmitted by a method wherein an electrode is connected to a heating resistor, and an electric conductive part of a thin film formed to be thinner than the electrodes is established. CONSTITUTION:A shape of a resistor 3 is so constructed that a length of the resistor at a width direction central part is shortened so as to vary a resistance value to a width direction of electrified parts 4a, 4b. That is, the resistance value of the resistor 3 between the electrified parts 4a, 4b is so constructed as to be small at the central part in the width direction of the electrified parts 4a, 4b and as to grow larger toward both edge parts. Further, the resistance value of the electrified parts 4a, 4b of a thin film is so constructed as to grow small to the resistance value of the resistor 3 and grow preferably one half or less. Heating during power conduction is so constructed as to be governed by heating in the resistor 3. Therefore, when a current is made to flow to the resistor 3, the current inversely proportional to a distribution of the resistance value flows to the resistor 3, and a large current flows to the central part. Consequently, when a current is made to flow to the resistor 3, heating temperature is high at the central part, and is decreased toward the edge part in gradient manner.

Title: Ink cartridge for ink jet printer
Inventor: MOCHIZUKI SEIJI
IPC: B41J2/175
Filed: 1990-04-02
Abstract: PURPOSE:To make it possible to inhibit air and printing ink in an ink tank housing an impregnation member from being agitated by reciprocating motion of a carriage, by forming a partition member in an ink chamber for taking off the ink from the ink tank. CONSTITUTION:In the process of feeding ink, air may enter to an ink chamber 12 before the ink is completely consumed, air in the ink chamber 12 usually stays at an upper portion of the ink chamber 12 by its buoyant force. But, if reciprocal motion of a carriage 2 is violent, in other words, the motion of the carriage 2 is high speed mode, the ink has agitated contact with air in the ink chamber 12. But, since a partition member 13 is formed in a center portion of the ink chamber 12, the agitated contact is inhibited and air is prevented from flowing toward a printing head 3 from the ink chamber 12.

Title: Operation frequency changeable transmitting system
Inventor: SADA CHIZU
IPC: H04L25/49
Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To change-over a system frequency by outputting operation frequency change-over information in the form of signal polarity inversion at a transmission side and detecting the operation frequency change-over of a transmitting part through the use of the violation of '0' of a CMI signal at a reception side. SOLUTION: An NRZ signal inputted to the transmitting part 8 is converted into a CMI code signal by a uni-polar/CMI converting circuit 3. When a frequency change-over signal is inputted to a terminal 2, the outputs of the positive and negative poles of a driver circuit 4 are inverted and outputted to a transmission path 9. A receiving part 18 receives the inverted signal with a violation detecting circuit 10 and a pulse transformer 11 and it is inverted by an inverting circuit 12 again. After the outputted CMI code signal is waveform-reshaped by an equalizer circuit 13, transmitted to the CMI/uni-polar converting circuit 15 with an amplifier 14. The violation detecting circuit 10 detects the violation of '0' by inversion and transmits change-over information to a PLL circuit 17 with a frequency change-over circuit 16 and the PLL circuit 17 changes-over an operation frequency.

Title: Natural circulation type boiling water nuclear reactor
Inventor: KONISHI HIDEO
IPC: G21C15/02
Filed: 1989-04-10
Abstract: PURPOSE:To prevent effectively a damage of a turbine and a down-grading of an operating efficiency by expanding an upper part of a reactor core shroud toward the surface of a boiling water and by forming an increasing cross-sectional area of a flow passage, therewith. CONSTITUTION:An upper part of a reactor core shroud 3a expands toward a surface of a boiling water and is constituted by forming an increasing cross- sectional are of a flow passage. A coolant passing through a reactor core 2 forms a two-phase flow of a steam and a water and flows upwardly in a straight tube part of the reactor core shroud 3a at a rather high velocity. However, as the cross-sectional area of the flow passage is increasing according to a height to which the flow reaches above the reactor core shroud 3a, the flow velocity gradually decreases. Finally, the flow velocity of the two phase flow at a periphery of the surface 11 of the boiling water, decreases to one in several or one tenth of the flow velocity just after passing through the reactor core. Therefore, a vapor liquid separation can be easily conducted, a carry-over and a carry-under diminish substantially. Consequently, a damage of a turbine B and a down-grading of an operating efficiency can be effectively prevented.
