Title: Heater material
Inventor: TANAKA KUNIO
IPC: E01C11/26
Filed: 1993-06-07
Abstract: PURPOSE:To prevent a change in an electrical resistance value even if it is used repeatedly, and improve heating efficiency by winding a flexible heat generating mixed spinning yarn strip round the outer peripheral surface of a flexible core material. CONSTITUTION:A heater material has a fiber structure body mainly composed of a flexible heat generating mixed spinning yarn strip 3 formed by spinning mixedly stainless steel fine wires of 20-80weight% and heat resistant non-conductive yarn strips 4 of 80-20weight% so as to generate heat by contact resistance between these mutual steel fine wires when an electric current is supplied. This fiber structure body forms a flexible insulating coat 5 on the surface of a complex heating body arranged on the outer peripheral surface of a flexible continuous core material, so that this heating material 1 is formed. In such constitution, since the heat generated from the flexible heat generating mixed spinning yarn strip 3 is distributed uniformly on the outer peripheral surface of the core material, heat efficiency is improved. When compressive strain is applied repeatedly to the heater material 1, since the strain is absorbed by the whole fiber structure body, a change in an electrical resistance value or wire disconnection can be prevented, so that durability to bending can be also improved.

Title: Production of magnetic head
Inventor: YAMAMOTO TATSUSHI
IPC: G11B5/127
Filed: 1989-05-29
Abstract: PURPOSE:To allow magnetic recording and reproducing of a high surface recording density with an azimuth recording system by setting the direction where grooves for coil windings are formed at a prescribed direction. CONSTITUTION:The grooves 11 for coil windings to be provided on core block half bodies 1 of the magnetic head are moved and worked in the direction to provide the disposition where the slopes of magnetic core layers 6 juxtaposed in the half bodies 1 are always inclined downward from the surface on the side forming the grooves 11 and the side opposite to the advancing side of a grinding wheel at all times and in the same direction27 as the direction of the rotating tangent component at the lowermost point of the rotary grinding wheel 7 when the above-mentioned grooves 11 are formed across the magnetic core layers 6 juxtaposed to the block half bodies 1. The formation of the boat- shaped grooves for the coil windings are, therefore, not formed by the difference in the azimuth. The shorting of the soft magnetic metallic thin films to each other beyond insulating thin films by the ductility of the metal is thus obviated. The magnetic recording and reproducing of a wide frequency range at the high surface recording density with the azimuth recording system are possible in this way.

IPC: B23Q17/20
Filed: 1981-08-31
Abstract: PURPOSE:To aim at accurately finding the position of a sensor when it touches, by compensating a point of sampling with the product value of time and speed ranging from the point of sampling at the actual position to the point when the touch sensor comes into touch, in case of the above captioned system available for a numerically controlled machine tool, and so on. CONSTITUTION:Moving a table 10, when a workpart 16 on the table and a feeler 15 of a touch sensor 13 come into touch after passing a point tr of sampling and thereby a touch signal TS is emitted, a clock signal is counted by the input of a signal RD from a readout circuit 9 at a point tj of sampling, at a time measuring circuit 17 while a correction operational circuit is open. For example, the clock signal of 200KH is counted to the extent of a point P when the feeler 15 touches and thereby a time t is to be found. In addition, at a speed counter circuit 18, speed is found in advance from actual values Aj-1 and Aj of sampling points tj-1, tj and t, while at a correction counter circuit 19, time t is multiplied by speed v and the actual value of the sampling point tj and the multiplied value v.t are added up at an adder 20; the actual value of a P point is to be found by setting the position when the touch sensor 13 touches down as Aj+v.t.

IPC: G01B11/00
Filed: 1982-08-04
Abstract: PURPOSE:To detect exactly the positions of respective beams by constituting a titled device in such a way that the irradiation of the plane to be scanned by the plural beams deviates in the main scanning direction, disposing photodetection parts perpendicularly on the scanning line of the beams, putting out the beams when a photodetection part detects said beams. CONSTITUTION:Plural beams B1-B5 are deviated in the main scanning direction on the scanning lines thereof, and a photodetector E is disposed for the same perpendicularly on the scanning lines. For example, a photodiode having good responsiveness is used for the photodetector E. The plural beams overlapped in the auxiliary scanning direction are deviated respectively by the distance D at which no influences are given to the other beams. The distance D is required to be at least half the size of the beams. The beams B1-B5 are all lighted initially, then the beams are put out in order of detection with detectors. Since the putting-out of light after the detection is accomplished successively for the respective beams, the positions of the beams are exactly detected even if the beams overlap on the plane to be scanned in the auxiliary scanning direction.
