IPC: H02P23/16
Filed: 1984-02-22
Abstract: PURPOSE:To reduce the offset error by controlling the third phase with a signal that the symbol of the sum of the outputs of PID (proportional, integrating and differentiating) controllers are inverted. CONSTITUTION:The current values flowed to the first and second phases of 3- phase stator windings are fed back, compared by a counted value of adders 10, 11 to obtain the first and second phase current commands from PID controllers 13, 14, respectively. On the other hand, the third phase current command is not calculated, the outputs of the controllers 13, 14 are input to an adder 28, and the signal that the symbol of the sum of the output of the controller 13 and the output of the controller 14 is inverted is input to a power amplifier 18. Thus, the offset error can be suppressed to the prescribed range, thereby saving a multiplier, a D/A converter, the PID controller and a current detector for one phase.

Abstract: PURPOSE:To obtain an InP single crystal contg. iron or tin with a simple device when a phosphorus vapor pressure is exerted in a semi-closed vessel covering a crucible to grown an InP single crystal by the liquid encapsulation Czochralski method (LEC method) by adding iron or tin to a raw material to specify the phosphorus vapor pressure. CONSTITUTION:A specified amt. of an InP polycrystal and an iron foil as the additive are charged into a crucible 2, a sealant is placed thereon, and a high- pressure vessel 1 is filled with high-pressure gaseous N2. The phosphorus vapor pressure in semi-closed vessels 6 and 8 is controlled to 0.01-4atm by a vapor feed means 10, and an InP single crystal is grown by LEC method using a pull shaft 5. An InP single crystal added with iron or tin not having an impurity hardening action like S and Zn is obtained by this method. Furthermore, since the phosphorous vapor pressure is controlled to <=4atm, the lifting shaft needs not be encapsulated with an encapsulated medium, and the structure of the device is simplified.

IPC: G11B20/10
Filed: 1984-02-21
Abstract: PURPOSE:To reduce the noise due to the clogging of a head or an error in the tape driving direction having a certain width in the tape width direction, by allocating data on even and odd sample groups of the same channel for each scan and also recording those data at position separate from each other to the scanning direction.

In other words, those samples are written with the sample address set at 0 and frame addresses set at 0, 8, 12, 4.... Then the sample address is replaced once, and the writing is carried out again with control given to the frame address when the frame address is set at 7 and after the sample of WR7 is written. In such a way, the samples are distributed in a matrix of (4X16). In this case, the odd and even sample groups are separated from each other for each channel.

Title: Composite electrode and its production
Inventor: NAKANOUCHI YUKIO
IPC: G01N27/41
Filed: 1989-02-10
Abstract: PURPOSE:To enhance the adhesive property, output characteristic, responsiveness and long-period stability of the electrode by using a specified Pt thin film layer vapor-deposited on the surface of a solid electrolyte element substrate and a Pt paste layer having specified grain diameter printed on the surface. CONSTITUTION:The Pt thin film 2 having 0.01-1mum thickness is vapor-deposited on both sides of the solid electrolyte element substrate 1 by sputtering with good adhesion. When the thickness is smaller than 0.01mum, the reaction interface of the electrode is reduced. When the thickness is greater than 1mum, the gas permeability is deteriorated. The ionic current value is decreased in both cases, when a voltage is impressed. A Pt paste obtained by dissolving Pt grains having 0.05-10mum diameter in an org. solvent is screen-printed on the thin film 2 and then calcined to form the Pt paste layer 3. Since the lower thin film 2 involving an electrode reaction is used as the vapor-deposition electrode for sputtering, high output and responsiveness can be expected. As the upper paste layer 3 is porous, the diffusion of gas to the interface and responsiveness are not hindered. The weak lower layer is protected by the upper layer, and the deterioration of the electrode is prevented.

A lever 1 is placed into the hollow grooves 7a of the lower die 7, and its tongue pieces 3 are opposed to seat parts 7b. Next, when the press is moved downward, the male die 6 abuts on the lower die 7, and sandwhiche the lever 1. Then, the compressing punches 8 move downward to compress the tongue pieces 3. The tongue pieces 3 plastically deform to protrusively form circular cylindrical shafts 4 to the end edge of the lever 1. Thereupon, the male die 6 and the punches 8 are moved upward and the lever 1 is dislodged. The lever 1 protrusively provided with the shafts 4 is bent of both and edge parts 2 in the next process and the axial centers of both shafts 4 are aligned, whereby the lever is completed. Since the shafts are protyusively compression-formed integrally with the metallic sheet by the above, accuracy is high and there is no degradation in strength.
