Patent JP-H0536934-A (JP)
Title: Semiconductor device
Inventor: TOMIUE KENJI
IPC: H01L27/108
Filed: 1991-07-31
Abstract: PURPOSE:To obtain a semiconductor device which does not malfunction in such a case that the ON/OFF of the power supply is repeated within a short period of time. CONSTITUTION:When the power supply source VCC is turned OFF, a potential of a node N3 is lowered up to -VCC, a PMOS transistor Q3 turns ON, causing the ground voltage from the ground voltage source VSS to become equal to a substrate bias potential VBB via the PMOS transistor Q3. Thereafter, even when the power supply voltage source VCC turns ON, the substrate bias potential VBB is lowered with reference to 0V. Therefore, this voltage under the transitional condition when the power supply voltage source VCC is ON becomes a negative voltage which is almost zero. Accordingly, a threshold voltage of an NMOS transistor formed on a semiconductor substrate 200 will never become excessive. Therefore, a semiconductor will not malfunction.

Title: Digital modulating device
Inventor: TSUTSUI HIDEO
IPC: H04L27/20
Filed: 1997-07-16
Abstract: PROBLEM TO BE SOLVED: To appropriately reduce the spread of the spectrum of a modulated signal output, to reduce the number of parts to be adjusted, and to attain miniaturization by providing a digital filter means for inputting a source base band signal and a burst signal, and forming a base band signal to be applied to a digital modulating means. SOLUTION: I phase and Q phase base band signals DATA-A and DATA-B and a burst signal are inputted to a waveform shaper 1, and waveform-shaped into satisfactory pulse waveform by the waveform shaper 1 by using a twofold clock. Afterwards, the waveform-shaped base band signals are transmitted to digital LPF 12A and 12B, and tramsitted to two phase modulators 4A and 4B after the unnecessary spread of spectrum after an intermediate frequency switch 10 is band-limited. Thus, the spread of the spectrum of the modulation signal output in switching a transmitting state and a non-transmitting state can be reduced by applying the digital SPF 12A and 12B using the burst signal.

Title: Track running type inspection device
Inventor: INOUE KAZUHIDE
IPC: B61L1/12
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To prevent a plurality of inspecting sections which run along a track from colliding with each other. SOLUTION: A track running type inspection device is provided with a plurality of inspecting sections 1 which run along a track 2 and a central controlling section 17. Every inspecting section 1 has a driving unit 15 which varies a running speed of the inspecting section and a position detector 9 which outputs a signal to correspond to a position on the track 2 of the inspecting section 1. Based on the position signal from the position detector 9 of each inspecting section 1, a controlling means 72 of the central controlling section 17 calculates at all times a running distance between every one of the inspecting sections 1 and the other one which is just ahead of the inspection section in the onward direction.  When the running distance of the inspecting section 1 is the same as or larger than a specified reference distance, the controlling means 72 keeps the inspecting section to run at a specified rated velocity. When the running distance becomes smaller than the reference distance, the controlling means 72 controls the driving unit 15 of the inspecting section 1 so as to reduce the running speed of the inspecting section 1 to the one lower than the rated speed temporarily until the running distance of the inspecting section 1 becomes the same as or larger than the reference distance.

Title: Fluidized-bed type boiler
Inventor: NOTANI TAKEO
IPC: F22B1/02
Filed: 1982-11-02
Abstract: PURPOSE:To increase the combustion efficiency of a fluidized-bed furnace by a method wherein the density of heat transfer pipes on the furnace wall at a vacant column part, through which a gas containing unburnt matter flows, is reduced in order to completely burn an unburnt gas passing through the vacant column part. CONSTITUTION:A part of heat transfer pipes constituting a furnace wall at a vacant column part 7 are thinned out so that the density of heat transfer pipes is made less dense here than that at a fluidized-bed part and the uppermost part of the vacant column part. The length of the zone of the furnace wall, over which the heat transfer pipes are thinned out, is preferably made enough long for unburnt matters passing through the vacant column part to completely burn. A part of heat transfer pipes 8 may be arranged so as to bypassing the furnace wall instead of to thin-out the heat transfer pipes 8 constituting the furnace wall. The partial removal of the heat transfer pipes 8 constituting the furnace wall at a part just above a fluidized bed results the reduction of the heat quantity transferred at the vacant column part, resulting in raising the temperature at the vacant column part and consequently enabling to completely burn the unburnt matters (CO and the like) passing through the vacant column part.

Title: Reflective body for radar of shell
Inventor: RUUDORUFU HERERU
IPC: H01Q15/14

Abstract: The method of mounting a radar reflector on an artillery shell contemplates providing a body constituted by a functional element and a sleeve element formed rotationally-symmetrical about a lengthwise axis of said body with at least one explosive device arranged at least at the neighborhood of an outer surface of said sleeve element near to one end of said sleeve element and remote from the functional element. The body is mounted on the artillery shell and the explosive device is detonated in order to establish a form-locking connection of the sleeve element with the shell. The detonation of the explosive device severs the sleeve element at the region of said one end of said sleeve element in order to provide a substantially straight-lined closure of the sleeve element about the artillery shell in order to avoid undesirably altering ballistic characteristics of the artillery shell.

Filed: 1987-07-30
Abstract: PURPOSE:To detect the voltage non-equilibrium in three-phase AC, by detecting the difference between the DC output voltage of a diode bridge and the terminal voltage of a condenser by a voltage difference detection part. CONSTITUTION:The difference between the DC output voltage, that is, pulsating voltage of a diode bridge 3 and the voltage between the terminals of a condenser 5, that is, the DC smoothing voltage of the diode bride 3 is detected by a voltage difference detection part 7. When the voltage drop in the forward direction of a diode 4 is neglected, the voltage between the terminals of the condenser 5 is set so that the time constant of this circuit becomes large as compared with the cycle of three-phase AC, said voltage becomes the voltage of the max. value of a pulse wave. When the voltage difference of the detection part 7 reaches a scheduled value, a switching part 9 is operated. By this method the voltage non-equilibrium in three-phase AC is detected.
