Title: Image forming device
Inventor: ARAI YOSHITOKU
IPC: G01S17/08
Filed: 1992-08-05
Abstract: PURPOSE:To improve the accuracy and speed of recognition by previously recognizing a stationary obstruction, and correspondingly to the arrangement of the stationary obstruction, recognizing whether a body except the stationary obstruction is a person using a device or not. CONSTITUTION:After predeterminate time from a time of turning on an electric source, a sensor is actuated, and a spot where some body is detected is recognized and remembered as the existing place of a solid body, namely an obstruction. A distance sensor 6 is actuated on a sampling signal given by a control section 11 to measure a distance to the body. A parameter extracting section 8 extractinigly computes feature parameters required for the recognition and various judgments of the body decided as responded object on distance data to each body, and sends them to a recognizing-judging section 9 and writes them in a memory 13. The judging section 9 receives the parameter and judges about the body being a responded object. Correspondingly to the recognized stationary obstruction, whether the body except the stationary obstruction, for example a body being a responded object, is a user for the image forming device or not is judged.

Filed: 1987-09-14
Abstract: PURPOSE:To set the arbitrary quantity of heat and to eliminate the necessity of applying heat externally by forming a resistance heater for heating a chip to a predetermined temperature on the main surface of the chip. CONSTITUTION:A self-heating resistance region 2, a region 3 for performing the original function of a semiconductor integrated circuit, many bonding pads 4 of the integrated circuit, and a pair of pads 5, 6 for applying a voltage to the region 2 are provided on a chip 1 of the integrated circuit. The region 2 is formed on the main surface of the chip, and operated as a resistance heater. The region 2 is disposed on a region not used for the region 3 of the normally original function, i.e., a region outside the pad. The quantity W of heat of the region 2 becomes W=V<2>/R when it is represented by a voltage V applied between the pads 5 and 6, and a resistance value R between the pads 5 and 6. Accordingly, when the voltage of 10V is applied and the resistance is 10 ohms, the quantity of heat of 10W is obtained. When the quantity of heat of this degree is obtained, the chip 1 can be sufficiently held at high temperature.

Title: Form for molding projection and recesses of concrete
Inventor: HIRATA TAKAYOSHI
IPC: B28B7/36
Filed: 1993-09-17
Abstract: PURPOSE:To prevent projected parts of a pattern forming sheet from being crushed by the pressure of a concrete even if a relatively thin sheet is used as the pattern forming sheet. CONSTITUTION:As a pattern forming sheet 1, a thin material having shape retention properties can be used. A number of projections and recesses are randomly formed, for example, in a bricked form on the surface of a hard and thin sheet of, for example, vinyl chloride, polystyrene, or polypropylene by vacuum forming. Recessed parts 1b are formed on the flat surface part and, as a result, the remaining part forms projected parts 1a of the pattern forming sheet. A supporting frame 2 is abutted on the back surfaces of the projected parts 1a (the top surface) of the pattern forming sheet 1. In this manner, the load of a concrete is transmitted to the recessed parts of the pattern forming sheet as a tensile load. The tensile load is transmitted to the support frame abutted on the back surfaces of the projected parts. The pattern forming sheet having a high strength to a tensile load can keep its shape in cooperation with the supporting rigidity of the supporting frame without crushing the projected part of the pattern forming sheet.

Filed: 1989-09-06
Abstract: PURPOSE:To select three or more of stable points by an external parameter by forming a coupled quantum well to a p-i-n i-layer and utilizing the anti- intersection phenomenon of optical absorption transition generated by the change of an electric field. CONSTITUTION:A coupled quantum well is shaped to a p-i-n i-layer, and the anti-intersection phenomenon of optical absorption transition generated by the change of an electric field is utilized. That is, a GaAs multiple quantum well layer 1 is composed of coupled quantum well structure consisting of a thick well and a thin well partition ed by a thin barrier displaying conduction band structure at applied voltage Vex of V1 and V2. Discrete level is formed by a quantum effect in the quantum well, but V1 and V2 are turned upside down when levels A, B are observed in the levels, and A and B repel in case of strong coupling between the wells at that time. Optical transition related to the level A is altered discontinuously when voltage increases from V1 to V2 by the effect of the levels. Accordingly, a large number of stable points can be selected by an external parameter.

IPC: F02D41/22
Filed: 1985-10-17
Abstract: PURPOSE:To secure the traveling stability of a vehicle at the time of cornering by operating a slip ratio between a tire and a road surface from the revolving speed of driving and driven wheels and a steering condition and reducing a driving force when said ratio is larger than a set value. CONSTITUTION:A driving-wheel and a driven-wheel revolving speed detecting means (a), (b) and a steering condition detecting means (c) are provided. A slip ratio between a tire and a road surface is operated (d) from the detected signals of these means and, when the slip ratio is judged (e) larger than a set value, a driving force is reduced earlier by making closing control (f) of a throttle valve earlier, and the like. Accordingly, traveling stability of a vehicle at the time of cornering can be secured. And, since the steering condition is also being detected, there is no fear of the slip ratio of the driving wheel being operated greater than it appears.

Filed: 1989-09-07
Abstract: PURPOSE:To execute advance priority selection control even with a slight time difference by inputting a strobe signal representing the input of a signal to a selection control circuit so as to output a signal inputted precedingly. CONSTITUTION:When a signal data A is inputted to a terminal a of a selection circuit 1, a strobe signal S(A) ('0') is fed to an OR circuit 5-1. As a result, a level '0' is outputted from the OR circuit 5-1 and a level '1' is outputted from a NOT AND circuit 6-1. On the other hand, an inverted strobe signal inverse of S(A) is inputted to an OR circuit 5-2, from which a level '1' is outputted and the NOT AND circuit 6-1 outputs '1'. That is, while the signal data A is inputted to the terminal a of the selection circuit 1, even when a signal data B is inputted to other terminal b, the output of the NOT AND circuit 6-1 remains logical 1 and the signal data A is outputted succeedingly from the selection circuit 1.

IPC: B60L3/00
Filed: 1990-09-04
Abstract: PURPOSE:To stop operation quickly upon power interruption regardless of the high frequency level during normal control by detecting power interruption based on a fact that the incremental variation rate of specific high frequency component exceeds a specific power interruption detection set value. CONSTITUTION:Output from a bandpass filter circuit 9 fluctuates constantly according to the state of feeder circuit for a PWM converter during normal control, e.g. the impedance of substation or the distance between the substation and an AC electric motor car. The output level is detected by a circuit 13 for detecting the variation rate which increases abruptly upon power interruption and when the output level exceeds a higher harmonic variation rate power interruption detection set value being set by a power interruption detection set value setting circuit 10A, a comparator 11 functions to output a power interruption detection signal 12 thus stopping the operation of the PWM converter 4 and a VVVF inverter 6. According to the constitution, power supply to other powering vehicle or a fault point is interrupted quickly at the time of regeneration.

Title: Bipolar transistor
Inventor: KONDO MASAO
IPC: H01L31/11
Filed: 1998-08-19
Abstract: PROBLEM TO BE SOLVED: To reduce the base running time of electrons to improve the operating speed. SOLUTION: In a bipolar transistor using an SiGe mixed crystal layer as a base, the Ge compsns. of an emitter-base junction region and base-collector junction region which is adjacent the base layer are made higher than the Ge compsn. of the base layer. The smaller the diffusion coefficient of B in the SiGe layer is the higher the Ge compsn. is. Hence the diffusion of B from the base layer can be suppressed by making higher the Ge compsns. of the emitter- base junction region and base-collector junction region, which sandwich the base layer than the Ge compsn. of the base layer.
