Abstract: PURPOSE:To efficiently implant an ion and to continuously and efficiently obtain an inner face-treated thin pipe by inserting a hollow pipe for conducting the ion into the thin pipe and isolating the inside of the hollow tube from the outside by a membrane. CONSTITUTION:A hollow pipe 44 is inserted into a thin pipe P made of a polymer material. A membrane 48 is fixed to the tip of the hollow pipe 44, and the inside of the hollow pipe 44 is airtightly isolated from the die 46 side. A cylinder 41 is heated, and a material P' is introduced from a hopper 43. A hollow screw 44 is rotated to transport the molten material P' toward the die 46. The molten material P' is cooled by the die 46 and extruded from a gap between the die 46 and a protruding rod 49 to form the thin pipe P. Under these conditions, the inner face of the thin pipe P is irradiated with an ion through the membrane 48.

Title: Ink jet recording method
Inventor: SHIOTANI MAKOTO
IPC: B41J2/01
Filed: 1987-04-25
Abstract: PURPOSE:To enhance a dot shape and fixing properties and water resistance in a printing part when a printing is conducted with a high density on a paper which has been subjected to sizing and provided with a fiber exposed on the surface to be recorded, by a method wherein a time required for ink drips to reach to an initial transfer amount after being applied to the recorded material is set shorter than a time required for the ink drips to start infiltrating into the recorded material. CONSTITUTION:A volatile solvent in an ink starts to evaporate just after an ink drip is applied to a recorded material. Therefore, the amount of the ink is reduced to less than an initial transfer amount to the recorded material after a fixed time elapsed. If this time is determined as (te), the value (te) depends on the composition of the ink and the initial transfer amount to the recorded material. If a time required for the ink to wet the recorded material, the infiltration of the ink to the recorded material can be considered to depend on (tw). The value (tw) is determined according to the wetting properties and evaporating speed of the ink and the wetting properties of the recorded material. When a combination meeting a requirement of (te)<(tw) is selected from among various inks, papers, and heads, a good dot shape is obtained, and the fixing properties, the water resistance, and the discharge stability of a head can be enhanced.

Title: Protective relay device with countermeasure function to immobility of circuit breaker
Inventor: OKADA AKIRA
IPC: H02H3/28
Filed: 1989-04-22
Abstract: PURPOSE:To prevent malfunction by providing overcurrent detectors to the secondary circuit of a defferentially connected current transformer and to the secondary circuit of another current transformer provided to the same power line respectively and by issuing an interruption immobility command when both current detectors and a percentage differential relay are actuated. CONSTITUTION:When an internal fault is caused to a transformer 1TR, a percentage differential relay 87 is actuated and a circuit breaker CB1 trip signal is issued. If CB1 did not trip, the current will flow to the secondary side of CT1 and CT3 and overcurrent relays 51F1 and 51F2 are actuated. As the percentage differential relay 87 and two overcurrent relays are actuated, trip signals are issued to circuit breakers CB3 and CB4. In case the secondary side of a current transformer CT1 is earthed, no trip signals will be issued to the breakers CB3 and CB4 as the overcurrent relay 51F2 is not actuated.

IPC: H04N5/44
Filed: 1982-06-15
Abstract: PURPOSE:To detect video signal through a digital circuit by counting up the number of horizontal synchronous pulse for a fixed period longer than the sum of a vertical synchronous period and an equivalent period. CONSTITUTION:A horizontal synchronous pulse is impressed to an input 21 of an AND circuit 23 and a control pulse longer than the sum of the vertical synchronous period and the equivalent period is impressed to an input 22.

The contents of the latch circuit 26 are compared with prescribed values N1 and N2 by the 1st and 2nd comparators 28, 29 respectively. The comparator 28 outputs the ''H'' level when the contents of the latch circuit 26 are >N1 and the comparator 29 outputs the ''H'' level when the contents are <N2. Consequently, a video signal detecting output can be digitally obtained from an AND circuit 31.

IPC: G11B15/02
Filed: 1979-08-13
Abstract: PURPOSE: To avoid the delay in recording start, by providing the means storing the recording mode up to now after the mode is changed over from the recording to the halt.  
     CONSTITUTION: Since the main switch 55 is closed with the mounting of cassette, this switch 55 is held closing state as the halt mode of the tape recorder. Further, the change-over switch 54 is changed over with the relay RL 2 . Accordingly, the capstan motor 50 keeps revolution toward the arrow F even if it is made to the stop mode during the forward recording (playback) mode and also keep the revolution toward the arrow G even if the halt mode is selected during the reverse recording (playback) mode. Thus, if the tape recorder is again set to the same mode as before, the rotation leading time of the motor 50 is not required and the tape can immediately start with normal running.

Title: Holding structure of clip
Inventor: MURASE TSUKASA
IPC: F16B5/06
Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To eliminate the generation of a sink mark on the back surface of a molding. SOLUTION: A sink mark at the molding time can be dissolved when a molding M is made thin. When a connection edge 8 is made thin, a clip installation part 1 is easy to deform and the coming off of the clip 2 is feared, but when a reinforcement claw 19 is provided on the clip 2 and the clip 2 is stored in the clip installation part 1, the expansion deformation of the connection edge 9 is regulated by that the reinforcement claw 19 is positioned to the outside of the connection edge 8. Therefore, as the holding force for the clip 2 is not dropped even if the connection edge 8 is made thin, the sink mark of the molding M is dissolved and the exterior of the molding M can be held consequently.
