Title: Manufacturing method of mold coil
Inventor: TERADA SETSUO
IPC: H01F5/06
Filed: 1978-07-19
Abstract: PURPOSE: To make easy a manufacture of a mold coil by utilizing in place of a metallic mold a light hardening resin layer, which formed on an outer surface before impregnating the hardened resin.  
     CONSTITUTION: A high strength glass fiber, a glass tape-like deorganic material are wound around an electromagnetic coil 1 having the widings wound around it. In this case, if the glass fiber material may be used, a resin unimpregnated coil should be prepared by winding a tape layer 3 around the outer circumference of n insulation layer 2. A light hradening resin layer 4 is formed by a roller plating or a screen printing on the outside of the unimpregnated coil to harden the resin layer 4 by a violet ray. A charge material is mixed into the light hardening resin layer 4 to select its visicousity to prevent the internal glass fiber or the tape layer 3 from intervention of the resin. An uniform resin layer 4 is formed on the outer surface, the resin layer 4 is used a substitution of the golden mold, a change of a coil design is performed as soon as possible to make easy the manufacture of the coil.

Title: Method and device for magnetron sputtering
Inventor: MIYAMOTO TAKASHI
IPC: H01B13/00
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To securely obtain uniform film quality by executing sputtering in such a manner that the whole face of a substrate is applied with a vertical magnetic field. SOLUTION: By applying the whole face of a substrate 2 with a magnetic field vertical to the substrate face, the place in which the components vertical to the substrate face is made zero in the magnetic field is eliminated. Namely, by executing sputtering in such a manner that the substrate 2 is deviated from the position in which the magnetic field horizontal to the substrate face is formed, the converged region of the magnetic line of force is not formed, and the formation of a uniform film is made possible over the whole face of the substrate 2. Thus, in accordance with the magnetic force generated by a cathode, a coil or the other permanent magnet M and an electromagnet composing the sputtering device, the arranging position of the substrate 2 in the device is set to the one deviated from the position in which the magnetic field horizontal to the substrate face is formed.  As to the preferable concrete measure, the number of magnetic poles is increased from two to three, moreover, their magnetic force is controlled and also, the substrate 2 is arranged to a suitable position.

Title: Operating device for heat pump
Inventor: KAMESHIMA KOUJI
IPC: F24F11/02
Filed: 1982-05-28
Abstract: PURPOSE:To perform an operation and maintenance of an air conditioning system at a low cost, by varying a set value of temperature of hot water at a range in which an air conditioner is capable of handling a load, and minimizing an input of a heat pump on the same load. CONSTITUTION:Overload judging devices 7a and 7b, which detect opening degrees of regulating valves 3a and 3b for a quantity of water, and based on the results, output overload signals S1 and S2, output ''1'' overload signals S1 and S2 when the regulating valves for the quantity of water are fully opened, and ''0'' overload signals S1 and S2 in the case of the opening degree other than the full openig degree of the valve. A controller 6 for a fuel feed quantity regulates an opening degree of a regulating valve 5 for a fuel feed quantity so that deviation between measurements Tm of hot water temperature and a set value Te of a hot water temperature attains zero value. A computer 8 for a hot water temperature computes and outputs the set value Te of a hot temperature corresponding to a change in a load of an air conditioner side. As a result, the set value Te provides for a minimum value at a range in which the air conditioner is not brought into an overload state, and this permits the operation and maintenance of the air conditioning system at a low cost.

Title: Tracking mechanism for optical information recording/ reproducing device
Inventor: HIROKI TOMOYUKI
IPC: G11B7/09
Filed: 1988-04-14
Abstract: PURPOSE:To attain stable tracking even when the interval between tracking pre-groups is narrowed by providing a means to control one side of a means to detect the reflected light quantity of tracking optical beams. CONSTITUTION:The reflected light of the tracking sub-beams received by an optical head 3 passes through current-voltage converters 5a and 5b, and then, respectively made into signals TA and TB. The preceding signal TB is set at a constant level, the signal TA which receives the effect of a pit is modulated by the presence and absence of the pit with the level of the TB as a maximum value, and a DC level is decreased for the portion of modulation. There, when offsetting is added to the TA by an amplifying circuit 6a, offset fluctuation by means of the modulation is eliminated from an output TA' of the amplifying circuit 6a, and the DC level is made the same as the TB (TB'). Consequently, the TA' and TB' are made into a track error signal without an offset error through a differential amplifier 7 and an LPF 8. Thus, the correct tracking can be attained through a phase compensating circuit 9 and an actuator driving circuit 10.

Filed: 1978-07-26
Abstract: PURPOSE: To cause the phase of reproducing data signals and the phase of error decision signals to agree with each other practically by combining a First in first out memory (FIO) and an RAM to constitute a memory of the reproducing part.  
     CONSTITUTION: PCM signals such as video of one horizontal period which passed through series-parallel converter 31 are written in FIO32 by write command 37, and simultaneously, gate 38 is closed and read command 39 is not applied to FIO 32. Meanwhile, a correct or error signal according to decision of a CRC signal, etc., which is added for every prescribed number of samples of PCM signals dependently upon error detector 33, is written in RAM35. When gate 38 is opened after one horizontal period, storage contents of memory 32 are read out and are written in RAM35. Consequently, the practical phase shift between error decision signals dependent upon detector 33, which completes decision at a one-horizontal period end time, and data signals is prevented by a simple constitution where the FIO and the RAM are used.

Filed: 1983-05-23
Abstract: PURPOSE:To eliminate unevenness of spectral transmittivity due to optical elasticity and to make damaging hard to occur by reinforcing the boundary part between the hard part and soft part of an optical fiber bundle for image transmission which is formed by an acid dissolving method. CONSTITUTION:An adhesive 6 is charged among optical fibers 1 near the boundary part 5. In this case, the adhesive 6 is not charged closely among the respective optical fiber, but in a porous state wherein numbers of forms 7 are present. The amount of the residual adhesive 6 is extremely small, and no large stress is applied to the circumference of the boundary part 5 even when the adhesive uses a thermosetting type adhesive with a 10<-14>/ deg.K coefficient of expansion, so that neither optical elasticity nor the damaging of optical fibers occurs. Further, the circumference of the boundary part 5 is reinforced sufficiently by using a slightly hard adhesive. The viscosity of the adhesive used for the reinforcement is preferably about 200 centipoise. The remaining amount of the adhesive after the setting of the adhesive is preferably minimized to a value enough for the reinforcement of the boundary part so as to prevent an optical fiber 1 from damaging owing to the difference in coefficient of expansion between glass material and adhesive which form the optical fiber, and close charging is not preferable. Further, the adhesive in use has preferably >=40% volatility.
