Title: Multifiber optical connector
Inventor: OBARA YUICHI
IPC: G02B6/38
Filed: 1988-03-25
Abstract: PURPOSE:To reduce the size of the optical connector by varying the arranging pitches of plural optical fibers with each other on the butt end face of a plug to provide coarse parts and dense parts so that optical fibers for light energy and fibers for light signals are made to coexist in the plug. CONSTITUTION:The arrangement of the optical fibers in the plug 1 has the coarse parts and dense parts. The optical fibers 14b for transmitting the light energy allow the intrusion of external noises therein without any problem and are, therefore, disposed at the dense arrangement pitch near the center of the plug 1. On the other hand, the optical fibers 14a for transmitting the digital light signals, etc., requiring identification are arranged at the coarse arrangement pitches on the outside of the plug 1 by taking the mutual leak coupling into consideration. One side of the optical fiber arranging face is reduced to about 2/3 the size of the plug having the ordinary uniform arrangement pitch and the finish diameter of the multifiber optical connector is reduced by about 10% if the arrangement pitch of the optical fibers 14b in the dense part is set at <=1mm and the arrangement pitch of the optical fibers 14a in the coarse part is set at 1.5mm.

Title: Activation judging device for air-fuel-ratio sensor
Inventor: SUZUKI HIROYOSHI
IPC: G01N27/406
Filed: 1991-04-02
Abstract: PURPOSE:To detect the activating point of an air-fuel-ratio sensor without deteriorating the air-fuel-ratio sensor. CONSTITUTION:Under the pump-current cut state for an oxygen pump element 11a of an air-fuel-ratio sensor 1, a current which is supplied into an oxygen concentration cell element 11b is cut with an injection-current cutting means for every specified period from the start of the current conduction to a heater 12. When the difference between the sensor voltages for the oxygen concentration cell element 11b before and after the cutting of the injection current becomes less than a specified value, it is judged that the air-fuel-ratio sensor 1 is in the activating state, and the pump-current cut state is released.

Title: Immersion nozzle for pouring molten metal and continuous casting method
Inventor: YAMAZAKI TSUYOSHI
IPC: B22D11/116
Filed: 1995-03-28
Abstract: PURPOSE: To supply molten steel having a uniform flowing speed into a mold by using an immersion nozzle, in which the cross section of a spouting hole is a rectangular shape having a specific value to the ratio of a long side and a short side and a rib having the shape widening downward in the upper part is arranged on the center line of the long side in the inner part of the nozzle. CONSTITUTION: The immersion nozzle 2 fitted between the mold and a tundish is provided with the spouting hole of vertically downward. The cross section of the spouting hole is a rectangle, in which the ratio of the long side and the short side is defined to be 3-20. The rib 3 whose upper part is widening downward in the upper part, is arranged in the center line of the long side in the inner part of the immersion nozzle 2. The molten steel stream 5 flowed in the nozzle 2 is collided against the rib 3 and the stream is divided. Since there is the inclining part in the upper part of the rib 3, the blanching is smoothly executed and the erosion of the rib 3 is little. Therefore, the molten steel stream 6 toward the mold is uniformized.

Title: Magnetic disc device
Inventor: SASAMOTO ASAO
IPC: G11B19/22
Filed: 1982-04-28
Abstract: PURPOSE:To prevent head crash through automatic braking at stopping of the rotating drive of a disc, by providing a brake releasing the braking through the supply of motor driving power. CONSTITUTION:At the rotation drive of a disc 1, when an AC input is applied, an electromagnetic coil 11 of a brake B1 is excited, an armature plate 7 is absorbed and detached from a brake shoe 9 to release braking. At the same time, a motor M1 is rapidly driven with capacitors C1 and C2 to prevent a magnetic head from rubbing on the surface of the disc 1. After a specified time, a positive characteristic thermister R1 is heated and the resistor is increased and the starting capacitor C1 is disconnected. When no AC input is applied at the rotation stop, no braking is made with the residual magnetic flux of the coil 11 and after a prescribed time a brake B1 gives braking through the lowering of rotating speed due to friction. Thus, head crash can be avoided.

IPC: G06F12/06
Filed: 1988-03-24
Abstract: PURPOSE:To execute the decision of the mounting of an option ROM without providing a detecting circuit by automatically deciding the existence of the mounting of the option ROM by means of a software and deciding a processing. CONSTITUTION:A program starts from the 0 address of a standard ROM 3-1, data to be set in an area 3-1b in the standard ROM 3-1 beforehand and the data to be stored in the corresponding address of an area 3-2a of an option ROM 3-2 are compared, and whether a comparison result coincides or not is decided. At the time of a coincidence, since the option ROM 3-2 is mounted, an option program stored in an area 3-2b of the option ROM 3-2 is added, and an exclusive-use pre-processing for executing the processing is executed. Thus, the detecting circuit can be made unnecessary, and simultaneously, a device having the option can be constructed only by mounting the option ROM.
