IPC: H01L21/316
Filed: 1987-06-16
Abstract: PURPOSE:To reduce a foreign matter and an impurity by continuously laminating a gate insulating film and gate electrode-wiring through a chemical vapor deposition method by using the same chemical vapor deposition device. CONSTITUTION:An silicon oxide film 2 is laminated onto a semiconductor substrate 1 consisting of silicon (Si), etc., by employing a chemical vapor deposition method (a CVD method), and the silicon oxide film 2 is used as a gate insulating film in metal-oxide film-semiconductor, a MOS transistor. A polycrystalline silicon film 3 is laminated by employing the chemical vapor deposition method in the same device as a device through which the silicon oxide film 2 is laminated. The polycrystalline silicon film 3 is used as a gate electrode and a wiring in the MOS transistor, and machined to a desired shape. Consequently, the semiconductor substrate is not moved, and the intrusion of an impurity and the contamination of particles, etc., is reduced extremely. Accordingly, the gate oxide film is held under a clean state at all times, thus acquiring high quality and high reliability.

Title: Measuring method of connection loss of optical fibers
Inventor: TAMURA YASUTSUGU
IPC: G01M11/02
Filed: 1977-12-15
Abstract: PURPOSE:To measure connection loss at the position where there is a connection point with high accuracy by entering light signal into an optical fiber from the position another from the opening face of the optical fiber existing before the connection part of the optical fibers. CONSTITUTION:When the light pulse signal generated by a light pulse signal generator 21 is condensed by a lens 22 and is entered to an optical fiber 18, the light signal is excited in its core. In this case, the excitation of the light smoetimes occurs in the fiber other than in its core and this becomes a measurement error and therefore this light is removed with a mode filter 24. Rayleigh scattering light is detected with a detection part 23 immedaite before the connecting part 19. This detection light is synchronized to the pulse signal from the light pulse signal generator 21 and is amplified in a lock-in amplifier 25 and is indicated in an indicator 26. This value is let to be M1. Next, the Rayleigh scattering light in the fiber 20 is measured and the value thereof is let to be M2, then the connection loss S is given by S=10 log M1/M2.

Title: Direct current reference voltage source
Inventor: SUZUKI TADAO
IPC: G05F1/56
Filed: 1985-07-09
Abstract: PURPOSE:To adjust the temperature characteristic of the break-down voltage between emitter collectors by inserting the resistance of the usual suitable value between base collectors of the transistor. CONSTITUTION:When the reverse direction voltage is applied through a constant electric current source P between the emitter collectors of a transistor Q, an electric current of 100muA is made to flow, and the value of a resistance R is changed, the temperature characteristic of the output voltage is also changed. At a certain transistor, when the value of the resistance inserted between base collectors is 6.5kOMEGA, the temperature characteristic of the break-down voltage comes to be zero between 0 deg.C-100 deg.C, and when 23OMEGA is increased for the resistance value, the temperature characteristic of the voltage comes to be the change of -1 PPM each time 1 deg.C advances and comes to be the change of +1 PPM each time 23OMEGA decreases. Once such a temperature characteristic is measured, the resistance value necessary to obtain the desired temperature characteristic can be found by the calculation. Thus, the direct current reference voltage source suitable to the equipment to use the battery can be obtained.

Title: Method and device for training adaptive equalizer tap coefficient
Inventor: KANDA YOSHINORI
IPC: H04L25/03
Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To prevent the convergence of training from being delayed by the influence of noise or the like by making both a target impulse response time window and a filter coefficient time window into fixed windows after predetermined convergence conditions are satisfied. SOLUTION: At a target impulse response time window part 1400, an updated target impulse response Bu inputted from a target impulse response updating part 1300 is converted to a time zone signal bu (D). In this case, a selector part fixes the position of a time window after a loop next to the loop satisfying prescribed conditions. Namely, when the ratio of power out of the time window to power in the time window of the target impulse response becomes lower than a prescribed value, it is discriminated to fix the time window later. According to this discrimination, the selector part of a filter coefficient time window part 1600 is controlled. A normalizing part normalizes b(D) into predetermined value and outputs a target impulse response bw (D), G which the time window is loaded, and an FFT part generates a frequency band signal Bw.

Title: Vehicle collision judging device
Inventor: KIMIJIMA MASAHIDE
IPC: G01P15/00
Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To provide a vehicle collision judging device capable of making an accurate collision judgment in a short time with a simple and inexpensive structure. SOLUTION: An acceleration sensor 10 outputs an acceleration signal S1 with the level corresponding to the magnitude of acceleration. An A/D conversion function section 20 converts the acceleration signal S1 into a digital signal D1. An amplification controller 30 amplifies the acceleration signal D1 at a higher amplification factor as the level becomes lower so that the peak value of the acceleration signal D1 is amplified to the expected voltage level. A filter 40 attenuates only the expected band of the digital signal D2 outputted from the amplification controller 30. A filter controller 50 receives the amplification factor from the amplification controller 30 and limits the attenuating action of the filter 40 when the amplification factor is small. A collision judgment section 60 makes a collision judgment based on an output signal D3.
