Title: Still image display device and its operation panel
Inventor: ITO MASASHI
IPC: G06T11/80
Filed: 1994-05-10
Abstract: PURPOSE:To display still images without physical pain and without the need for rotation or tilt of a monitor by combining scrolling with edit such as coordinate transformation or magnification/reduction corresponding to an image pickup angle. CONSTITUTION:When an image acquisition switch is depressed, image data are received by an input image memory 30 via an image signal input interface 10 by the command of a main processing section 70. When the content of the memory 30 is displayed as it is and a nontransfer display switch is displayed, an image edit means 40 reads data from the memory 30 by the command of the main processing section 70 and copies the data to an output image memory 50. Furthermore, when a vertical inversion switch is depressed, the means 40 reads data from the memory 30 by the command of the main processing section 70 to implement coordinate transformation for vertical inversion and transfers the result to the memory 50. During the processing of coordinate transformation by the means 40, an image displayed on an external display device is scrolled via an output interface 60 by depressing a scroll switch.

Abstract: PURPOSE:To establish a complete fail-safe function and to warrant high speed and safety for a job by providing a zero cross synchronizing pulse signal generating means, a discrimination data storage means and a fault detection means to the controller so as to detect a fault of a semiconductor element automatically in the ON/OFF state of a load. CONSTITUTION:When loads 15A, 15B are not driven in the clutch brake OFF state, input latch circuits 33A, 33B latch an OFF command signal from a drive operation panel 1 to turn off triacs 11A, 11B thereby allowing pulse signal generators 51A, 51B, 52A, 52B to output a zero cross synchronizing pulse signal. Thus, CPU 31A, 31B being a fault detection means compare a signal read by a control panel 30 with a discrimination data stored in memories 32A, 32B being discrimination data storage means so as to discriminate whether or not a fault takes place in the triacs 11A, 11B. In the case of brake ON state, an ON command given to the loads 15A, 15B is latched to the circuits 33A, 33B and an interrupt input from a power supply zero cross synchronizing circuit 20 is awaited.

Title: Current position calculating system and method therefor
Inventor: SATO HIROYUKI
IPC: G06F17/30
Filed: 1995-04-21
Abstract: PURPOSE: To calculate the current position of a vehicle in an accurate manner by searching such a road as being considered that the vehicle is properly traveling even in the case where there is no road in and around a vehicle estimated position detected by both distance and direction sensors. CONSTITUTION: An estimated position of a vehicle is determined with an absolute direction calculated by an output value of an azimuthal sensor 12 and a direction variation to be outputted from an angular velocity sensor 11. A pulse number to lee outputted by a car speed sensor 13 is counted, and a distance coefficient is multiplied to the counted value, seeking the traveling distance. A virtual current position is calculated from the traveling direction and distance, seeking a proposed point of the vehicle, and it is stored in a memory 25.  After this proposed point has once come to a state that there is none on the road, in the case where a first counting means value is more than the specified value but a second counting means value is less than the specified value, plural second virtual positions are formed in a position being separate as far as the specified distance from the proposed point. On the basis of these virtual positions, a second proposed point is formed, and thus a position of such a proposed point as the largest in reliability value among the proposed points becomes the current position of the vehicle.

Abstract: PURPOSE:To produce a mold for forming synthetic resin product in a short period of low cost by a method in which when the forming mold for foamable thermoplastic resin is to be produced, a thin film made by metal-spray is formed on the surface of the mold corresponding to the surface of a formed product, and further reinforcement-layer such as FRP is formed on the outer side of said thin film. CONSTITUTION:Thin film A, A' are formed on both surface of a removable mold 1 by spraying metal such as Al. Next, reinforcement-layers B made of FRP are formed on these thin films A, A'. After they are hardened, the removable mold is removed. Then, steam injection holes C, C' and a raw material filling hole D are bored. After the particles of the foamable thermoplastic resin such as polystyrene are injected into the hole D for filling raw material, and said hole is closed by a stopper. Thus, the resin is heat-formed by a autoclave, and the foamed product is obtained.

Title: Conference speech system with paging function
Inventor: IMANISHI TATSUYA
IPC: H04M3/56
Filed: 1989-04-19
Abstract: PURPOSE:To dispense with the call of an opposite party at a time decided in advance and to enable conference speech to be freely performed from a telephone set housed in the same PBX by enabling the voice of a conference caller to be heard from an installed speaker via a paging trunk passing a conference trunk. CONSTITUTION:The conference caller 6 captures a trunk 5 for conference by performing the operation of a telephone set at its own seat, and it is connected to the paging trunk 3. Since a speaker passing a paging amplifier is connected to the paging trunk 3', the voice of the conference caller can be heard from the speaker, and a conference call can be identified even when a corresponding person is absent at his/her seat. When bidirectional speech with the caller is desired based on the content of the conference, a line is connected to a null terminal for conference participation, which enables the bidirectional speech with the conference caller to be performed.

Title: Manufacture of semiconductor device
Inventor: TOMIKAWA TORU
IPC: H01L21/302
Filed: 1988-04-20
Abstract: PURPOSE:To form a tapered electric contact hole, to increase mechanical strength, and to acquire a highly reliable semiconductor device by forming a resist pattern having a step in the depth of a mask hole and by etching an interlayer insulation film using the resist pattern as a mask. CONSTITUTION:An interlayer insulation film 16 is eliminated by dry etching method by CHF3 gas, etc., using a resist pattern 27 having a mask hole 25 which consists of a hole 25a of a large diameter and a hole 25b of a small diameter, and a mask hole 26, etc., as a mask. As the time passes, the mask hole 25b of a small diameter on a photoresist 20 is damaged and at last disappears. Therefore, contact holes 28, 29 formed in the interlayer insulation film 16 are shaped in tapers 28a, 29a which are narrow inside and wide outside. Since a metal thin film deposited inside is not obstructed by a metal thin film 30b deposited on the flat interlayer insulation film 16, the step coverage b1/a1 becomes large, thus forming a mechanically firm and reliable electrode, etc.
