Title: Manufacture of floating type magnetic head
Inventor: MATSUBARA TAKAO
IPC: B24B21/00
Filed: 1989-05-15
Abstract: PURPOSE:To manufacture a large number of floating type magnetic heads having fine edge beveling with high yield by working the head by using a jig consisting of a soft grind medium and a medium guide with the shape corresponding to that of the magnetic head, etc. CONSTITUTION:A grind tape 10 is set from a grind tape delivery reel 8 to a take-up reel 9 via a tension sensor 11 and a grind tape guide 12 whose shape is fitted in that of the rail 6 of the magnetic head in advance. Next, linked thin film magnetic heads 14 are descended until prescribed tension is produced. At this time, the edge of the rail 6 comes in contact with the tape 10 having a gentle curve between the guides 12. Therefore, the beveling of the edge can be performed by reciprocating the reels 8 and 9 in forward and backward directions for constant time. The depth and the width of the beveling can be controlled with the tension and the reciprocating time of the tape 10.

Filed: 1987-05-21
Abstract: PURPOSE:To decrease the converging time even in a colored signal by applying Fourier expansion to an input signal by a digital filter section comprising a comb-line filter and plural basic filters, and recombining the signals after adaptive control. CONSTITUTION:A digital filter section 8 constitutes an adaptive digital filter in matching with a control section 9. The input signal inputted from an input terminal 1 is inputted to the comb-line filter and the output of an adder 200 is inputted to M+1 sets of second-order cyclic filters 50, 51,-5M. The (k+1)-th basic filter consists of a filter 5k, multipliers 3k1-3k6 multiplying coefficients pek, psk, qck, qsk and control coefficients wek, wsk and adders 2k1, 2k2 to apply Fourier expansion to the input signal approximately by the filter section 8. Then signals subject to adaptive control by the control section 9 arc combined again by (2M-1) sets of adders 2 and outputted to an output terminal 7. Thus, even the colored signal can reduce the converting time.

IPC: C23C10/28
Filed: 1983-07-06
Abstract: PURPOSE:To manufacture a heat exchanger excellent in corrosion resistance by forming one of metallic members to be braded of a brazing sheet, brazing without flux in vacuum or nonoxidizing atmosphere and at the same time, sticking metal baser than the metallic member or its vapor on the surface, and thereby forming a diffused layer or an alloy layer on the surface of the metallic member. CONSTITUTION:Metallic to be brazed to each other are made up of fins 3 and tubes 2 etc., and at least one of them is formed of a brazing sheet clad with brazing filler metal. After assembling, the metallic members are heated in vacuum or nonoxidizing atmosphere and brazed without flux. At this time, heating temperature is made above melting point of brazing filler metal of the brazing sheet and below melting point of the metallic member to prevent the deformation of the metallic member. By using base metal for a diffused layer or alloy layer formed on the surface of the metallic member including brazed part, it is corroded sacrificially to protect the metallic member. When forming the diffused layer or alloy layer, temperature is made below melting point of the brazing filler metal to ensure brazed part. It is necessary that the base metal has melting point below that of the brazing filler metal and can generate vapor.

Filed: 1982-07-14
Abstract: PURPOSE:To decrease the number of parts and make the assembling work easy, by a method wherein a plate plunger is used and a permanent magnet is disposed to the side of a coil frame in the plate thickness direction. CONSTITUTION:A yoke 11 is abutted to side of a coil frame 13 and recesses 12(a), 12(a)' of an intermediate yoke 12 are fitted to a projection 11(a) thereby the yoke 11 is combined with intermediate yokes 12, 12'.

Solid line represents magnetic flux by permanent magnets 20, 20' and broken line does flux by a coil 19. In this state, flux of the permanent magnets and flux of the coil are superposed at an air gap A and flow in opposite directions to each other at an air gap B. Consequently, at the gap A the magnetic flux is increased and the attractive force increased, whereas at the gap B the magnetic flux is decreased and the attractive force decreased, thus the plunger 14 is attracted towards the gap A. If the coil excitation is reversed, the plunger is attracted towards the gap B.

Title: Programmable counter
Inventor: KATOU GIICHI
IPC: H03K23/66
Filed: 1980-09-04
Abstract: PURPOSE:To shorten the time for the count execution start of a programmable counter, by providing a gate circuit having a delay circuit of four-gate components in the preceding stage of a D type FF. CONSTITUTION:When an LOAD terminal is set to L and a program data input terminal Pi is set to H, the output of an NAND gate 24 becomes H; and since an NAND gate 26 is H, a transmission gate TG28 is turned on, and a D type FF34 is set to H. Next, the LOAD terminal is set to H; and if a CEP or CET terminal is L, the output of the NAND gate 26 becomes L, and a TG31 is turned on, and the D type FF34, is held in the preceding state. When CEP and CET terminals become H together, the D type FF34 is inverted each time a clock terminal CP becomes H, and thus, count advances. Consequently, the propagation delay time to the count start is shortened to the time of four-gate components of NAND gates 25 and 26, an inverter 27, and the TG28.
