IPC: G11B5/09
Filed: 1987-06-30
Abstract: PURPOSE:To attain complete erasing even in the case of using plural magnetic recording media with different magnetic materials by providing an erasure current switching means switching an erasure current fed to an erasure head depending on the kind of the magnetic recording media. CONSTITUTION:With a mode signal S, e.g., at an L level entered into an erasure current switching circuit 13, a switch 14 is turned off and a drive circuit 12 supplies the erasure current decided by a resistor 16 to an erasure head 11.

Title: Input system for display information
Inventor: NOUMI YOSHIHIKO
IPC: G06F17/21
Filed: 1980-11-19
Abstract: PURPOSE:To use a cursor for graphic display in addition to characters and to determine its position easily by providing a code buffer which correspond to display characters, a graphic memory for a display pattern, and keys for inputting picture-element information. CONSTITUTION:When characters are inputted with alphanumeric keys, the coordinate data of a cursor are trnsferred to an MPU3. The MPU3 sets the codes of the character in an address of a code buffer 8 and the cursor advances automatically. When picture-element information is inputted with a graphic key 6, the picture-element information is held as a dot pattern in an address of a graphic memory 14 through the operation of a graphic-mode selection key 7. When a display key is operated, the MPU3 sends some coordinate data of display data having been inputted and at the same time, a display timing generating circuit 10 sends a row signal to the code buffer 8 and graphic memory 14. Those signals are converted by a series-parallel conversion part 15 into video signals as a cursor specified position on a CRT, thereby displaying the character and picture-element information simultaneously.

IPC: B23B35/00
Filed: 1987-06-30
Abstract: PURPOSE:To facilitate the decision of a drill diameter at time of drilling a hole in the printed wiring board, improving a working coefficient, and prevent the occurrence of defective products due to erroneous selection of a drill, by processing other different diameters of through holes after a through-hole having the same diameter is drilled continuously and then a through-hole having the same diameter of the above through-hole is drilled in the dummy section. CONSTITUTION:Many through-holes 11 with different diameters are drilled in a printed wiring board 1 which a conductive circuit 9 is formed at least on its one surface and which has a dummy section 4 separated after parts are loaded. In this case, the through-hole 11 having the same diameter is drilled continuously and the through hole 30 having the same diameter of the through- hole 11 is drilled in the dummy section 4, thereafter repeating the process where the drilling of through-holes having other different diameters is started. As this facilitates the confirmation of a hole diameter to be processed next, the corresponding drill can be selected without fail, resulting in improved working coefficient, and the defective products can be prevented from occurring, resulting in improved productivity.

Filed: 1979-12-18
Abstract: PURPOSE: To prevent the forward lifting of a running gear at the time of push-up movement, by providing a play between a track frame and equalizer bar.  
     CONSTITUTION: A vertically swivelling action of a track frame 3 is operated around a pivot shaft 2. Required dimensions 81 due to the swivelling motion of an equalizer bar 15 at the time of oscillation are ensured by the swivelling motion of a shaft 17. An elastic pad 31 acts so as to prevent both jolting momvenet of the shaft 17 and spreading motion of the track frame 3. The longitudinal displacement due to the swivelling motion of the track frame 3 is ensured by an action of the shaft 17 sliding on the inner ring of a spherical bush 16. Then, the equalizer bar 15 moves upward through a margin on the top, and makes a stopper to actuated, thus prevents the lifting movement of a running gear.

Title: Optical switch
Inventor: INOUE HIROAKI
IPC: G02F1/313
Filed: 1986-07-14
Abstract: PURPOSE:To improve quenching characteristics and to facilitate manufacture by providing a refractive index variation part on at least one of both sides of an optical branching part. CONSTITUTION:When the refractive index of the refractive index variation part 4 is decreased, a light wave incident on the optical branching part 5 from an optical waveguide 2 or 3 travels straight and is projected on an optical waveguide 8 or 7. The optical branching part 5 has the refractive index variation part 4, so the light wave incident from the optical waveguide 2 or 3 advances in a beeline without spreading in this area nor leaking to the optical waveguides 7 and 8, so the quenching characteristics are improved. Further, when the light wave incident from the optical waveguide 2 or 3 is reflected by the optical branching part 5 and projected on the optical waveguide 7 or 8, deterioration in quenching ratio is prevented by increasing the width of the optical branching part 4 and the width of the refractive index variation part 6. Consequently, an optical branching structure is obtained which has an excellent quenching ratio and is easily manufactured.

Title: Injection of fluidizing liquid
Inventor: SASAKI RYOKICHI
IPC: E02D5/44
Filed: 1987-07-02
Abstract: PURPOSE:To obtain a pile having great spherical footing without the needs for breaking bags by a method in which injection of a fluidizing liquid is stopped when the injecting pressure in a bag buried in the ground reaches a set pressure and restarted at a lower rate than the previous injection when a set lower limit is reached in a repeating manner until completed. CONSTITUTION:A bag 1 is attached to the lower end side of an existing pile 2 and a solidifying fluid liquid 5 is injected into the bag 1 through an injection tube 4 in the pile 2. The pile 2 is then buried in a pit 3 previously excavated and the liquid 5 is injected into the bag 1 from the tube 4. In this case, when the injection pressure reaches a set upper limit value P2, the injection is kept stopped until a set lower limit value P1. When the value P1 is reached, injection is retarted at a lower rate than the previous injection. The processes are repeated to complete the injection. Great amounts of the liquid 5 can thus be injected into the bag in a short time.

Abstract: PURPOSE:To realize the unmanned operation of a command issue system by using a command check means and a command issuing means which issues the commands permitted by the command check means. CONSTITUTION:A command issue system consists of a command check means 1 and a command issuing means 2. The user of an on-line system writes previously a desired command into a file and uses an on-line conversation processing system to start a command check program. Then the issued command is read out of the file based on said program. Then it is checked whether or not the command inputted from a terminal can be issued via an operator or the terminal. When no permission is obtained for issue of the command, this fact is displayed then a permitted command is issued. Thus an unmanned command issue system is attained.

CONSTITUTION:When a message addressed to a user is sent, the message is transferred to a message communication system into which the user is accommodated and a message transfer section 2 is started. The transfer section 2 extracts a name of a called party and a name of a caller from the message and informs the name to an undesired message list management section 3. When the name of the caller received from the transfer section 2 is registered in the undesired message list relating to the called party, the management section 3 does not store the message to the mail box of the user but abort the message. When the name of the caller is not registered, the message is stored in the mail box.
