Title: Polishing method for ferrule end face of optical connecter and optical connecter using ferrule thereof
Inventor: TAKEDA KEIKO
IPC: G02B6/24
Filed: 1989-11-20
Abstract: PURPOSE:To effectively prevent the generation of a crack at the optical fiber internal part by polishing other optical fiber end faces together with a ferrule end face by a polishing machine driven with its rotation. CONSTITUTION:A polarization plane retension optical fiber 21 having a stress imparting part 28 and the other optical fiber 22 having no stress imparting part are connected with fusion each other and the polarization plane retension optical fiber 21 is fixed inside a ferrule 23 so that this fusion connected part A is located at the ferrule 23 inside and the other optical fiber 22 is projected in a small quantity from the ferrule end face. The other optical fiber 22 end face is then polished together with the ferrule 23 end face by a polishing machine 26 driven with its rotation. Consequently, the impact force at the polishing time is not transmitted to the polarization plane retension optical fiber 21 having a stress imparting part 28 and the generation of a crack inside the plarization plane retension optical fiber 21 is prevented.

Title: Magnification/reduction controller
Inventor: IBA YOSHIAKI
IPC: G06T3/40
Filed: 1988-11-28
Abstract: PURPOSE:To easily and quickly calculate an approximate value by setting a complementary constant at the idle part of a higher rank bit. CONSTITUTION:When data are stored in a source register 2 via a data bus 1, a controller 3 interprets an instruction code received from outside and sets the value of a constant register 6. When the controller 3 receives an instruction to apply the logical arithmetic to 2 bits contiguous to the data stored in the register 2, the controller 3 decides the arithmetic to be applied to the data out of all logical arithmetic functions and sends a control signal to an arithmetic unit 4 to perform a logical arithmetic and to output the arithmetic result. The register 6 stores its holding data into a idle part if produced in a higher rank bit of a destination register 5.

Abstract: PURPOSE:To stabilize the contact state between a magnetic tape and a magnetic head and to make a VTR high performance by providing a groove whose cross section is gradually larger from a backward side to a forward side against the rotating direction in the circumferential surface of a rotary cylinder. CONSTITUTION:The groove 11 whose depth is deepened as well as the width is widened to make the cross section gradually larger from the backward side of an opening part 4 to the forward side of the following opening part 4 against the rotating direction of the rotary cylinder is provided in the circumferential surface of the rotary cylinder 3.

Title: Cutting tool
Inventor: TSUTSUI TOSHIO
IPC: B27G15/00
Filed: 1996-11-12
Abstract: PROBLEM TO BE SOLVED: To improve the workability and economy in the polishing operation of a cutter, the polishing accuracy, and the bonding strength of the cutter. SOLUTION: By providing notches 4, 4,... in a base 5 of a polygonal plate member including the tip line of a cutter 2, the area of the cutter surface 2f, which is to be polished, is reduced by the area of the notches. Further, the notches function as the discharging opening of the gas generated by accompanying brazing so that deterioration of the bonding strength by the introduction of the gas to the bonded part can be restrained so as to ensure a high bonding strength. With the same level of the necessary bonding strength, the bonding area can b reduced for the amount of the restrained bonding strength deterioration by the gas introduction.  Further, in the cutting process by rotating a cutting tool 1, the air flow according to the rotation flows into the notches to generate the 'leading edge effect' in the periphery of the notches so that the cooling of the cuter can be promoted and a good cutting ability can be ensured over a long term.

Title: Permanent magnet type reluctance type rotary electric machine
Inventor: SAKAI KAZUTO
IPC: H02K19/10
Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To realize a permanent magnet type reluctance type rotary electric machine which is designed small-sized to provide high output to realize the operation in variable velocity in wider range. SOLUTION: This permanent magnet type reluctance type rotary electric machine repels magnetic flux entering from the area between the magnetic poles, because a permanent magnet 6 arranged in a cavity area 5 formed along the magnetic pole axis is magnetized almost in a direction orthogonal to the magnetic pole axis and moreover raises magnetic resistance in the permanent magnet direction, because the specific permeability of the permanent magnet is almost 1. Accordingly, the magnetic flux of an armature coil 2 is distributed so as not to almost pass through the area between the magnetic poles but to pass through the iron core of the magnetic poles. As a result, uneven area is generated in the gap magnetic flux distribution, and a large reluctance torque is generated by the change in magnetic energy.

Title: Physical amount detector
Inventor: UESUGI HIROSHI
IPC: G01R33/09
Filed: 1990-11-06
Abstract: PURPOSE:To measure with good accuracy by setting each temperature coefficient TCR of an offset adjusting resistance and a gauge resistance to satisfy a specific formula, and restricting generation of an offset voltage in a wide temperature range. CONSTITUTION:A TCR of each of an offset adjusting resistance and a gauge resistance is set as follows. That is, supposing that the changing amount of the temperature of a gauge part from the room temperature is DELTATG, that of an adjusting resistance is DELTATOFFSET, and respective TCRs of the gauge resistance and adjusting resistance are represented by alphaG, alphaOFFSET, the changing amount of each of the resistances RG, ROFFSET due to the temperature change is expressed by a formula I. If DELTARG and DELTAROFFSET change with the same rate to the temperature, an offset voltage is never generated even when a large temperature difference is present in the circumstances. Therefore, a formula II is held from the formula I. In other words, alphaOFFSET should be set so as to satisfy the formula II. By changing each TCR based on the formula II, an offset voltage can be made small in a wide temperature range.
