Patent JP-H02223374-A (JP)
Title: Dc linear motor
Inventor: YONEDA TADAO
IPC: H02P7/00
Filed: 1989-02-21
Abstract: PURPOSE:To suppress fluctuation of thrust and to facilitate simplification and common use of control circuit by forming a stator core of a magnetic body having rectangular cross section and constituting a coil of conductors wound around the stator core then splitting the coil into plural blocks. CONSTITUTION:When a movable section 1 is positioned at the left end, sensors a', b', c', d' have H, L, L, L levels which are fed to a logic circuit 31. When an L level signal is fed, as a direction signal (f), in order to move the movable section 1, current flows from a DC power source E. The current interlinks with the flux of a permanent magnet 11 thus moving the movable section 1 to the right. When the movable section 1 moves by the length of the coil, output from the sensor b' is brought to H level and current flows from a transistor Tr 3 thus moving the movable section 1 to the right.

Title: Magnetic recording and reproducing method
Inventor: TAKAOBUSE KAZUYASU
IPC: G11B5/027
Filed: 1984-03-03
Abstract: PURPOSE:To record and reproduce many kinds of video signals simultaneously and efficiently by additionally inserting another magnetized locus into a guard band generated by increasing a tape travelling speed in parallel so that the guard band is left. CONSTITUTION:Since magnetic heads A1, B1 having head width wider than the width of a track to be reproduced are used, close recording between adjacent tracks due to superposed recording is performed. Since a reproduced output is not changed even if tracking is shifted within the difference between the head width and track width, an objective channel can be easily selected and reproduced. To reproduce video signals on an adjacent track and the track next to said adjacent track, its channel can be selected by shifting the relative positions between the magnetized locus and the magnetic head by one/two tracks.

Title: Preset resistance unit
Inventor: TOTSUTORI KENZOU
IPC: H03G1/00
Filed: 1979-04-05
Abstract: PURPOSE:To prevent a large output from being generated suddenly from a loudspeaker by automatically moving a volume control unit to a preset position when the power is put to work. CONSTITUTION:When the power is put to work, reference voltage V1 of preset resistor 10 is compared 13 with voltage V2 of volume 2 detector 11 coupling direct with volume controller 2 so as to obtain voltage + or -V3. Judging circuit 12 judges whether this voltage is within the range of preset voltage + or -V0 and when so, control circuit 40 drives motor 8 to shift volume detector 11 into the set range of voltage + or -V3. Simultaneously, loud-speaker 4 is connected by switching control circuit 19. Thus, volume controller 2 moves to a position set by the preset resistor and then the loudspeaker is connected, so that no large output will suddenly be generated from the loudspeaker in power feed.

Title: Pulse arc welding equipment
Inventor: MOCHIGURI SHIGEO
IPC: B23K9/09
Filed: 1980-03-31
Abstract: PURPOSE: To perform pulse arc welding with less sputter by periodically superposing the pulse current over the DC base current to be supplied between the wire electrode and base material.  
     CONSTITUTION: The input voltage is boosted by boosting transformer 58 and applied to both ends of spark gap 60, and the high frequency high voltage is generated by condenser 62 and coupling coil 64. The discharge is generated by the high frequency high voltage between wire electrode 20 and base material 18, but, since this discharge holding voltage is high and it occurs oftenly that only the pulse voltage supplied from main power source 26 cannot hold the discharge, a no-load voltage, namely the base current, which is surely larger than this discharge holding voltage, is flowed to auxiliary power source 28. That is to say, the welding is performed with the pulse voltage supplied from main power source 26 among the voltage supplied from auxiliary power source 28. In this way, the welding is started without contacting electrode wire 20 with base material 18, therefore, sputters generated at the time of welding start can be prevented.

SOLUTION: Relating to a firewall, after the user 3 connected to a communications network 4 is authenticated by a user authentication means 11, the electronic mail is requested to the electronic mail server 2 corresponding to the request of the user 3 instead of the user 3 by the electronic mail transfer request representing means 13 and the response from the electronic mail server 2 is transmitted to the user 3 by an electronic mail transfer response representing means 14. Since authentication by the user authentication means 11 is performed by a disposable password, even when an intruder eavesdrops the disposable password, authentication can not be performed by using it.
