CONSTITUTION:This magnetic head slider material has a composition represented by CoXNi2-(R)O2 (where 0.2<=x<=1.8). The coefficient of thermal expansion of this material can be easily regulated to (128-150X10<-7>/ deg.C in the range of the composition in the formula, and further, the hardness (Vickers) of this material is 550-600 and this material has physical properties close to those of 'Sendust(R)'. In order to obtain this material, CoO and NiO are used as raw materials and weighed so that the above composition is obtained, and these raw materials are crushed, e.g. in ethanol by means of a wet ball mill, dried, subjected to CIP forming, calcined in N2, and crushed. The resulting calcined powder is pulverized by means of a ball mill in a similar manner as above, granulated, and subjected to CIP forming and then to sintering. Further, specific amounts of MnO, TiO2, Y2O3, etc., may be added to the above composition as a base composition.

Title: Analog recorder
Inventor: KOBAYASHI SHIYOUICHI
IPC: G01D9/00
Filed: 1982-09-30
Abstract: PURPOSE:To enable continuation of recording by providing a means of detecting that the recording value reaches and exceeds the maximum or minimum value of the graduation scale of a recording paper and a inversion recording means of inverting the recording direction according to the detection signal. CONSTITUTION:A measuring signal generation circuit 1 outputs a physical or chemical variation to an arithmetic processing means 2 as eletrical measuring signal 4. The measuing signal 4 is initially converted into a digital value with an A/D converter 5 and inputted into a preset counter 6. When a large signal (peak value Np) considerably exceeding the scale span (n) of the recording paper is inputted into at the time t1, it is recorded up to the upper limits Su of the scale of the recording paper and a substraction of Np-n is done at the time t2 to make the signal negative in the polarity so that the recording is inverted. As a result, a fall line of m=1 is drawn and when it reaches the lower limit SD, the signal is outputted as remaining sigal of Np-2n and returned to be positive in the polarity and thus, the peak value of Np is recorded. This enables recording of correct signal values without skipping in recording by inverting the record at the upper and lower limits of the scale thereby accuring the reading of large and small signals at the same accuracy.

Filed: 1990-06-30
Abstract: PURPOSE:To obtain a compact and light-weight optical mouse having the minimized number of troubles and also improving the designing freedom degree of the mouse by providing an optical fiber group on the optical path of the light reflected from a pad to lead this reflected light to a detector. CONSTITUTION:When an optical mouse 24 is moved on a pad 4, a detector 3 reads a position information pattern of the pad 4 with the reflected light Q and outputs a read signal R. A signal processing circuit 5 receives the signal R and processes it to output a position signal S to display in order to show the position of a cursor in response to the mouse 24. The light Q received from the pad 4 includes a part having a large quantity of the reflected light and a part having a small quantity of the reflected light in accordance with the vertical and horizontal cyclic patterns of the pad 4. Thus the quantities of light made incident on the optical fibers forming an optical fiber group 2 are different from each other. Therefore the optical fibers provided on an end face 2b of the group 2 at the side of the pad 4 and the vertical/horizontal cyclic patterns formed on the pad 4 can be arranged in various forms suited for calculation of the moving amount and the moving direction of the mouse 24.

IPC: G03B27/62
Filed: 1989-07-07
Abstract: PURPOSE:To prevent the useless ejection of a copy sheet by maintaining the copy sheet previously fed so as to reuse it when a paper jam is detected and ejecting an uncopied sheet only unless the previously fed sheet is reused when copying is resumed based on judgement as to whether the sheet is reused or not after the paper jam is removed. CONSTITUTION:A copying inhibiting means 1B inhibits the copy sheet supplied from a copy sheet supplying means from being copied with the aid of a jam detecting signal from the original jam detecting means 1A. The uncopied sheet which is already supplied is not immediately ejected outside the device and maintained in a reusable condition by a copy sheet retaining means 1C. A judging means 1F judges whether the copy sheet is ejected or not without being copied according to the next copying mode. Thus, an uncopied sheet is prevented from being uselessly ejected.

Abstract: PURPOSE:To easily obtain a multilayer electromagnetic coll, by winding a flat tape by one or more turns and electrically connecting the opposite ends of conductors provided on the tape in the manner that the end of Nth conductor is connected to the end of the (N+1) conductor. CONSTITUTION:On the surface of flat tape T, there are provided conductors 1-6 which extend from one end Ta to the other end Tb of the tape T, approximately in parallel with each other and with an equal space from each other. The tape T is rolled by one turn such that the opposite ends Ta and Tb abut against one another.

For example, the end 1b of the first conductor 1 present on said tape end Tb is connected to the end 2a of the second conductor 2 on said tape end Ta. When current is supplied from a terminal at the end 1a of the conductor 1, the current flows through the conductor 1-6 integrated by those connections and arrives at the terminal at the end 6b of the conductor 6. In this manner, a multilayer electromagnetic coil can be obtained easily.
