Title: Protective circuit
Inventor: YAMANAKA HIDEO
IPC: H02H7/16
Filed: 1990-07-25
Abstract: PURPOSE:To prevent degradation of the performance of protective circuit due to failure of electrolytic capacitor by providing a circuit for detecting abnormal voltage across the electrolytic capacitor and an active conduction element which functions, when the abnormal voltage exceeds a predetermined level, to produce a failure signal of the electrolytic capacitor. CONSTITUTION:Upon degradation of the performance of an electrolytic capacitor C11, a ripple voltage appears across the electrolytic capacitor C11 and a current flows through series resistors R19, R17. Divided voltage is then applied onto the base of a transistor Q11 and a current flows through series resistors R14, R15. At that time, voltage applied onto the base of a transistor Q12 drops and a current flows through a LED D11 which thereby emits a light. Consequently, a phototransistor Q14 is conducted and a current flows through a capacitor C15 and a resistor R13 thus conducting a thyristor S11. As a result, a current flows from a terminal T1 through a resistor R11 and the thyristor S11 to bring a transistor Q13 into nonconducting state thus disabling a switching regulator A1.

Title: Manufacture of semiconductor substrate
Inventor: VOUTSAS TOLIS
IPC: H01L29/786
Filed: 1999-07-08
Abstract: PROBLEM TO BE SOLVED: To realize a method for manufacturing semiconductor substrate which can be suitably used in an LCD having a polycrystalline film having large crystalline particles therein. SOLUTION: A silicon microcrystalline film is formed on a transparent substrate so as to contain microcrystallites therein (S1). Thereafter the microcrystalline film is melted by annealing, such as excimer laser annealing (S2). Melting is carried out, so that some of the microcrystallites do not melt but remain in the microcrystalline film. Thereafter the microcrystalline film is polycrystallized with the remaining microcrystallites used as seed crystals (S3). Thereby a semiconductor substrate can be obtained which is suitably used in an active element such as TFT and has high quality of polycrystalline silicon film, having large particle diameters.

Title: Electron beam deflection circuit
Inventor: SAWARA KATSUJI
IPC: H01J37/28
Filed: 1982-11-05
Abstract: PURPOSE:To fix frequency characteristics independently of magnification and remove any change with priority given to magnification by compensating the loop gain fequency characteristics of an electron beam deflection circuit in relation to detection resistor and almost completely prevent the frequency characteristics from being changed. CONSTITUTION:A frequency characteristic variable circuit (F characteristic circuit) 11 whose frequency characteristics can be switched interlocking with a select switch 4 is inserted and connected between an error amplifier 1 and a power amplifier 2. In this case, the frequency characteristics of the F characteristic circuit 11 have three frequency characteristics F1 to F3 as shown in the figure and these frequency characteristics are alternatively selected interlocking with the select switch 4. As a result of such a selection, the open loop gain Gopen in the circuit always shows the same characteristics independently of the switching of detection resistor R0 as shown in the figure. As a result, even if magnification is switched, there does not occur any change in the loop gain frequency characteristics of a deflection circuit system and there does not appear any phase change in the deflection coil current. Thus, a change with priority given to magnification can be removed.

Title: Arbiter circuit
Inventor: TSUKAGOSHI MAKOTO
IPC: G06F13/362
Filed: 1989-07-27
Abstract: PURPOSE:To prevent the output of an acknowledge signal from being delayed by providing a request signal generating part and a priority order selecting circuit, which determines a priority order to an input request, and generating the acknowledge signal by selection information coming from the latter and an input acknowledge signal. CONSTITUTION:When request signals REQ A1 and REQ B2 are inputted, a request signal REQ 9 is outputted from an arbiter circuit by a request signal generating part 3. On the other hand, these request signals are inputted to flip-flops 10 and 11 by a priority order selecting circuit 4 and the priority order is determined by the rise or fall of a clock. When an acknowledge signal ACK 16 is inputted to the arbiter circuit, an acknowledge signal ACK A14 from the arbiter circuit to the request signal REQ A1 is outputted from an acknowledge signal generating part 13. Thus, a time from the input of the request signal to the arbiter circuit to the output of the acknowledge signal from the arbiter circuit can be shortened.

Title: Magnetic bubble element
Inventor: IMURA AKIRA
IPC: G11C11/14
Filed: 1985-09-06
Abstract: PURPOSE:To eliminate the variance of an in-plane magnetized layer and to realize a stable element characteristic, and further, to improve reproducibility and reliability by forming a transferring path making ion implantation in a crystal orientation having a channeling by hydrogen ion. CONSTITUTION:Hydrogen ion is implanted deeply in a bubble film in crystal orientation having channeling effect. Then, the second ion is implanted to desired depth in the surface area of the bubble film making the channeling effect off and a uniform flat damage layer (curve 5) is formed. Further, hydrogen is thermally diffused toward the film surface by using annealing process. At this time, hydrogen is trapped by the damage layer (empty bond in a crystal) formed beforehand, and an ion implanted layer (curve 6) in which uniform flat strain and hydrogen are distributed simultaneously is formed. Accordingly, this layer functions as an in-plane magnetized layer for bubble transferring.

IPC: G01N1/04
Filed: 1986-08-21
Abstract: PURPOSE:To easily and stably sample an extremely shallow layer of the surface of a magnetic tape of sampling coating film powder deposited among particles of a grinding stone after the surface of the test tape is ground and liquid components adsorbed to water adsorptive paper. CONSTITUTION:The grinding stone 5 is cleaned before a test, a roller 7 for adsorption on which the clean adsorptive paper 6 is stuck is set, and the stone 5 is rotated during the run of the test tape 1, so that the surface of the tape 1 is ground by the stone 5. Here, the pressure of a pressure roller 4 is adjusted to control grinding depth and ground coating film powder is buried in the grain boundary of the stone 5. A lubricant layer on the surface of the tape 1 is transferred to the surface of the stone 5, but transferred again to the oil absorptive surface paper 6 and never returns to the surface of the tape 1. Then the grindstone 5 is dipped in a solvent after the tape is ground by constant length, coating film components are extracted and the surface lubricant layer is extracted by the adsorptive paper 6. Those extracted samples are analyzed by an analyzing device to take a qualitative and a quantitative analysis. Thus, the extremely shallow layer of the surface of the magnetic tape is easily sampled.

Title: Zero dispersion multimode fiber
Inventor: KADOWAKI MAKOTO
IPC: G02B6/10
Filed: 1987-08-07
Abstract: PURPOSE:To eliminate mode dispersion by deterioration with age by providing the microbends of a single space frequency which can shift the space frequency component of the microbends generated by the deterioration with age to a clad. CONSTITUTION:This zero dispersion multimode fiber 1 is constructed by having the microbends 2 of the single space frequency in the clad. The space frequency component of the microbends generated by the deterioration with age can be thereby shifted to the higher frequency band in such a manner that the basic waveguide mode can be coupled to the radiation mode even with the min. component of the space frequency of the microbends in an optical fiber generated by the deterioration with age and, therefore, the coupling between the waveguide modes is not generated. The waveform distortion of the signal transmitted by the mode dispersion is thus improved.

Title: Submersion countermeasure device for vehicle
Inventor: MIYAKE RYOJI
IPC: E05F15/16
Filed: 1999-07-09
Abstract: PROBLEM TO BE SOLVED: To reliably open the window pane on the driver's seat side when a vehicle is submerged by providing a submersion detecting means for detecting the submerged state, and controlling a submersion backup circuit to allow only a window opening action at the time of submersion. SOLUTION: An automatic window operation switch SWA has no relation to a window action regardless of its connection to the UP side or the DOWN side at the time of submersion, i.e., a normal control circuit IC1 has no relation to the window action at the time of submersion, therefore a window glass 17 can be reliably lowered by the DOWN action of a manual window operation switch SWM even if the normal control circuit IC1 becomes inoperable at the time of submersion. Waterproof coating is preferably applied to specific members, e.g. the circuit components of a submersion backup circuit 10, an UP side switch circuit 13, and a DOWN side switch circuit 14 required to operate at the time of submersion, in this submersion countermeasure device.
