Title: Manufacture of magnetic scale
Inventor: YOSHIOKA TAKAMOTO
IPC: G01B7/00
Filed: 1985-12-17
Abstract: PURPOSE:To record a magnetic lattice in a state that an output variation and a lattice pitch error are minimum, by impressing a recording current of the same polarity to a magnetic head at every recording wavelength, so that the magnetic lattice can be formed. CONSTITUTION:A pulse current impressed to a recording head is positioned exactly by a laser length measuring instrument, etc., and in accordance with a wavelength lambda, a pulse of the same polarity of positive or negative is made to flow continuously, and recording is executed. A magnetic field distribution of a recording head, which is generated when a pulse current shown in a figure (a) flows to its recording head becomes as shown by a broken line in a figure (b), and a detection output which is obtained after recording of a magnetic lattice has been ended becomes a sine wave in which an impressed position of the pulse current and a peak output of the magnetic lattice have coincided, as shown by a full line. When the magnetic lattice is formed in this way, a recording interval can be set to two times thereby, comparing with a conventional method and a magnetic interference is decreased, and a phase shift is scarcely generated. Accordingly, even if saturation recording by which an output is scarcely varied is executed, no lattice error is generated, the accuracy is improved, also the variance is decreased, and the productivity is improved.

Title: Vacuum monitoring element
Inventor: OZAKI KAZUYUKI
IPC: G01L21/18
Filed: 1985-12-20
Abstract: PURPOSE:To measure the pressure from an atm. pressure region up to a high vacuum region with one kind of vacuum gage by making use of the moisture monitoring effect that the pulverized particle film of metallic titanium on a crystal resonator possesses. CONSTITUTION:After silver electrodes are formed on both faces of the crystal resonator, the pulverized particle film of the metallic titanium is formed on one silver electrode surface side in such a manner that at least the silver electrode surface is covered. The result as shown in the graph is obtd. by measuring the frequency change rate of the crystal resonator when the pressure in the measuring atmosphere of the vacuum monitoring element is increased from 1X10<-6>Torr to the atm. pressure. Such frequency change of the crystal resonator by the vapor deposited metallic titanium film is considered to arise from the effective adsorption and desorption of moisture to and from the vapor deposited titanium film. The vacuum degree in the vacuum vessel of a vacuum device is made measurable by forming the element in such a manner that a large amt. of moisture can be adsorbed and desorbed to and from said element by controlling the conditions for vapor deposition according to the magnitude of the pressure of gaseous nitrogen.

Title: Silk fibroin powder as wound coating material and its production
Inventor: TSUBOUCHI KOZO
IPC: A61L15/16
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To make it possible to produce silk fibroin powder which has a relatively good adaptability to man, is in a powder form and is, therefore, easily dealable with various kinds of forms of a skin defect part and is easy to handle due to its high apparent density at a low cost by pulverizing non-crystalline fibroin films. SOLUTION: This process for production consists in refining silk fibers, then dissolving the refined fibers into a soln. of an acid or neutral salt. Low- molecular materials are removed by dialysis from this soln., by which an aq. fibroin soln. is obtd. When the silk fibers are dissolved by the acid, the soln. is dialyzed after neutralization with an alkali. The aq. fibroin soln. is spread on a plate and is adhered onto a roll surface to get rid of moisture, by which the film-like fibroin is obtd. The non-crystalline fibroin powder as the wound coating material is obtd. by pulverizing the same. The fibroin powder produced by this method has the relatively high apparatus density and has, therefore, a lower possibility of splashing. The powder is convenient to handle at the time of medical treatment.

Inventor: MATSUNAGA MASAYUKI
IPC: H04N5/335
Filed: 1985-12-19
Abstract: PURPOSE:To obtain easily a composite video signal by stopping the drive of a reset gate of an output section during the period of synchronizing pulse generation of the composite video signal to eliminate the need for the addition of period signals at an external circuit. CONSTITUTION:When signals corresponding to a drive pulse phiRS and a horizontal synchronizing signal SB are inputted to input terminals 41, 42 of an AND gate 40, a drive pulse phiRS' is outputted from an output terminal 43. The drive of the reset gate is stopped by the pulse phiRS' during the synchronizing pulse generation period P of the composite video signal SV. Thus, a video output signal SO' includes a drive stop period (noiseless period) equal to the period P in a reset noise component 13. When the signal SO' is inputted to an input terminal 21 of the external circuit, the signal SO' has only to be given to an inverter 22 and an LPF 23 and the signal SV is formed at an output terminal 25. Thus, the operation for adding the signal SB is not required and the composite video signal is obtained easily.

IPC: H02P9/04
Filed: 1996-10-29
Abstract: PROBLEM TO BE SOLVED: To protect a control signal input terminal from a short-circuit current when water content or the like permeates, and prevent the output voltage from abnormally increasing by arranging a ground pattern connected with the ground terminal of a semiconductor switching element between a power source terminal and the control signal input terminal. SOLUTION: A ground pattern (e) connected with an ground terminal (d) is arranged between a power source terminal (a) and a control signal input terminal (c). When water content or the like permeates, a short-circuit current flows from the power source terminal (a) to the ground pattern (e), and the control signal terminal (c) is protected from a short-circuit current, because the ground pattern (e) is interposed, when the power source terminal (a) and the control signal input terminal (c) are short-circuited. As a result, a semiconductor switching element can be prevented from unnecessarily continuing the state of electrical continuity, and the output voltage of an AC generator can be prevented from increasing abnormally.
