Patent JP-S552017-A (JP)
Title: Printer apparatus
Inventor: SUZUKI OSAMU
IPC: B41J9/38
Filed: 1978-06-19
Abstract: PURPOSE:To print a character within one character pitch clearly all over in a printer apparatus wherein only the printing portion does a shuttle movement, by making the width of plate springs smaller than the width of yorks. CONSTITUTION:A driving portion comprising a magnet 4 and a york 5 is fixed, and a printing portion comprising plate springs 1 and printing pins 2 is separated from the driving portion to permit only the printing portion to do a shuttle movement. The width ts of the plate spring 1 (the direction of the width being the same as that of the shuttle movement) is made smaller than the width t of the york 5 and minimized, so that the printing pin 2 can act all over the width of the york. Thus since the width of the plate spring 1 is smaller than the width of the york the magnetic flux from the york which acts on the plate spring during the shuttle movement is kept almost even to permit high quality printing.

Title: Magnetic recording and reproducing device
Inventor: OOTANI NAGAKI
IPC: G11B15/087
Filed: 1986-03-31
Abstract: PURPOSE:To quickly discriminate whether the reproduction mode is coincident with the recording mode or not by providing a filter transmitting only one kind of reproduced pilot signal among four kinds of reproduced pilot signals and detecting the reproduced pilot signal from the filter. CONSTITUTION:When the reproducing mode and the recording mode are coincident, the pilot signal is reproduced sequentially in the order of f1 f2 f3 f4 f1 f2... and the reproduced pilot signal f1 is outputted from the band pass filter 14. The reproduced pilot signal f1 is detected by a detection circuit 15, subject to sample and hole in the timing corresponding to the center of the field and converted into a digital signal by an A/D converter 18 while the level 1 is used as a reference conversion level. When the reproducing mode and the recording mode are coincident in this way, the output of the A/D converter 18 changes periodically as 1 0 0 0 1 0 0 0 1.... Thus, whether or not the reproduction mode is coincident with the recording mode is discriminated in a comparatively short period within 4 fields.

Title: Detection of sheath damage of power cable under live condition
Inventor: SOMA KENICHIROU
IPC: G01R31/08
Filed: 1984-04-12
Abstract: PURPOSE:To prevent an dielectric breakdown accident by detecting the presence or absense of the damage of a cable sheath, by inserting a DC current measuring apparatus into one of earth wires of a cable, and opening and closing the other earth wire thereof to measure the current thereof. CONSTITUTION:A DC current measuring apparatus 7 is inserted into one of the earth wires 5 of a cable and a switch 6 is interposed to the other earth wire 5. At first, the switch 6 is closed to form a closed circuit and a stray current is measured by the DC current measuring apparatus 7. Succeedingly, the switch 6 is opened to measure a DC current and, if a sheath 3 has no damage in the measurement in this state, no closed circuit is formed and, therefore, the DC current is not measured but, when damage is present in the sheath 3, the closed circuit is formed through a damaged part and a stray current is measured.

Title: Suspension structure of driving belt
Inventor: ROBAATO SHII BAAFUIIRUDO
IPC: F16H55/38
Filed: 1989-03-27
Abstract: PURPOSE: To restrict uncomfortable and unusual noise and reduce the loss of driving transmission by finishing the surface of a driving pulley in contact with a driving belt to be a rough surface. CONSTITUTION: When a subsidiary brush 12 is jumped up to a non-operation position, a driven pulley 42 comes near to a driving pulley 48 to cause the looseness of a belt 29, resulting in the driving pulley 42 to run idle and the subsidiary brush 12 not to run.

Title: Automobile constant speed travelling device
Inventor: TANIGAWA MITSUARI
IPC: F02D9/02
Filed: 1978-06-22
Abstract: PURPOSE: To smooth a transient characteristic of speed and acceleration, by means of providing a compensation circuit for smoothly operating a speed change.  
     CONSTITUTION: In the state of a directing circuit 5 not directing a constant speed travel, a transistor Tr comes to be on-state because of a signal being outputted from the directing circuit 5. Accordingly, in this state, a current to be charged to a condenser C flows out to the earth passing through a resistor R 4  and the transistor Tr. Consequently, with the resistor R 4  if selected to a suitable value, the condenser C can be set to a voltage near the final value for the control at a constant speed, and the vibration of useless speed change due to a vehicle speed at the time of control start can be prevented. If the directing circuit 5 indicates the constant speed travel, the condenser C works originally as the phase advance condenser.

Title: Method for repairing pipe
Inventor: YOKOSHIMA YASUHIRO
IPC: B29C63/08
Filed: 1993-04-01
Abstract: PURPOSE:To provide a method for repairing a pipe which enables repairing a large-sized pipe efficiently using a lining material which is lightweight and easy to handle. CONSTITUTION:A small-sized lining tube 2 impregnated with a thermosetting resin is stuck spirally to the inner wall of a pipe while compressed air is supplied into the lining tube 2. With the lining tube 2 expanded by the air pressure, a heating fluid such as hot air is fed into the tube 2 to cure the resin. The use of the small-sized lining tube 2 as a lining material facilitates the production and transport of the tube 2 and reduces the cost. Since the lining tube 2 is easy to handle, the lining operation can be conducted easily and efficiently. Moreover, since the amount of the rein injected in the lining tube 2 is relatively small, the resin can be cured in a short time to reduce the time of the repairing operation.
