Title: Loop pattern verification system
Inventor: KIYOUHATA YOSHIHIRO
IPC: G06F17/50
Filed: 1989-12-01
Abstract: PURPOSE:To grasp and verify the shape of loop patterns by tracing patterns divided at branch points from a start point to an end point and deciding an invalid loop pattern in accordance with the existence of a pattern connected to the branch point. CONSTITUTION:A graphic pattern is divided at all branch points (a) to (d) and the divided patterns 1 to 5 are stored in tables (a) to (c). Two optional branch points, e.g. (a), (d) are set up as the start point (a) and end point (d) of a loop pattern, routes from the start point (a) to the end point (d) are traced, flags indicating traced patterns out of the patterns 1, 3, 2, 4 arrived at the end point (d) can be stored in the tables twice, and when an untraced pattern 5 connected to the traced routes is not left in the tables, a valid loop pattern is decided. Thus, the shape of all the loop patterns 1 to 5 can be grasped and verified.

Title: Semiconductor device
Inventor: FUJII TAKASHI
IPC: H01L29/06
Filed: 1999-11-01
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device having a diode element structure that, while the reverse recovery characteristics of a diode element are maintained, the avalanche breakdown voltage and contact resistance of the diode element are modified. SOLUTION: p- type anode layers 2 are selectively formed in the surface on one side of the surfaces of an n- low-impurity concentration substrate 1. n- surfaces 3 being exposed without being formed with the layers 2 are covered with each insulative film 4. A plurality of the selectively formed layers 2 are electrically connected with a common electrode 5 constituting an anode electrode. Impurity ions of an amount necessary to obtain the targeted reverse recovery characteristics of a diode element are dispersedly implanted in the layers 2. As the total area of these layers 2 becomes narrower than the formation area of the conventional p- anode layers, the impurity concentration in each layer 2 relatively becomes high. As this result, the avalanche breakdown voltage of the diode element is high and the contact resistance of the diode element results in being modified.

Title: Sound noise generation preventing device for satellite broadcasting
Inventor: MAEJIMA HIROSHI
IPC: H04B1/10
Filed: 1993-12-13
Abstract: PURPOSE:To prevent the generation of a sound noise from a receiver at the time of changing a sound mode from a monophonic mode to a stereophonic mode by inhibiting the insertion of a PN signal only for a prescribed time at the time of changing the sound mode. CONSTITUTION:On the transmitting side of satellite broadcasting, a sound mode signal 11 is inputted to a mode change detecting part 12, and at the time of detecting a change in a sound mode, a pulse signal is outputted for a certain fixed time. On the other hand, a PN code generating part 14 generates a PN code 15 and a PN signal detecting part 16 finds out AND between the pulse signal and the PN code 15 and outputs a PN signal 17. Thereby at the time of changing the sound mode, the PN signal 17 is fixed to a low level for a certain fixed time. The PN signal 17 is inserted into the outside of a sound data area by a PN signal adding part on the transmitting side. When the sound mode is changed from the monophonic mode to the stereophonic mode like a system for always inserting a PN signal, the instantaneous generation of a nuisance sound noise like 'bachi' in the receiver can be prevented.

Abstract: PURPOSE:To effectively remove a waste gas and to prevent the inconvenience due to heating by removing the heat and waste gas caused at soldering time with a cooling gas removal means. CONSTITUTION:The substrate 2 loading a part on in advance is placed in the specified position on a supporting base 1 and a beam projection part 3 is moved to the specified position on the substrate 2 by being moved with a driving part 4. At this time, a gas blowing out duct 6 and suction duct 7 are moved together with the beam projection part 3. The gas is thereafter blown out of the gas blowing duct 6 and the suction of the gas body is started by the suction duct 7. A high energy beam is then projected toward the lead of the part on the sub strate 2 from the beam projection part 3. The heat and waste gas caused at the soldering time by the beam projection part 3 is removed by blowing a specific gas from the gaseous body blowing duct 6 of a cooling gas removal part 5 to such the gas and waste gas by the gas suction duct 7. Consequently the efficiency of the high energy beam is improved to prevent the irregular reflection of the beam.

IPC: B08B9/04
Filed: 1996-11-07
Abstract: PROBLEM TO BE SOLVED: To sense the position and passage of a spherical pig and automate reciprocating motion, emission and recovery of the spherical pig by sensing the magnetic line of force of the spherical pig by a magnetic sensor provided in a pipeline and a magnetic sensor fitted being shifted in the position from the above-mentioned sensor. SOLUTION: After light oil fed from a tanker is stored in a pipeline 1, a spherical pig is charged from one side part of the pipeline 1. When the spherical pig sticks closely into a fixed position of a reducing pipe 1d of a start part 1b, compressed air is fed to advance the spherical pig, and after confirming its passage by a magnetic sensor 4 on the start side, the light oil in the pipeline 1 is recovered into a tank 8. In the shifting process of the spherical pig, its magnetic line of force is sensed by the magnetic sensor 4 so as to be able to confirm its passage.  Since three magnetic sensor 4 are provided being shifted in the positions in the lengthwise and circumferential directions of the pipeline 1, even in case of a demagnetizing force part passing through the lateral magnetic sensors, for instance, the magnetic line of force can be sensed by the magnetic sensor at a top part.

Filed: 1994-12-16
Abstract: PURPOSE: To designate the route of a data frame on a real time basis by designating the route with permission signals obtained by decoding route designation information provided in a data frame in an event driving interface part EDI. CONSTITUTION: In a system which monitors/controls a data communication network 100 transmitting the series stream of a binary bit, the input part of EDI 110 is connected to the network 100, route designation information 106 of the data frame 102 is decoded and identified and the permission signals A, B, C and D are generated/outputted. A multiplexer 120 outputs the series bit stream to one of output paths 1-4 in response to the permission signal. While route designation information 106 is decoded in EDI110 at that time, a buffer 130 buffers the data frame and applies it to the data input of a multiplexer 120. Thus, the route of the data frame can be designated on the real time basis.

Abstract: PURPOSE: To obtain an inexpensive and compact photometry device with a simple constitution by providing a first photometry means executing the photometry of a part of a picture and outputting the result as a first photometry signal and a second photometry means averaging in time the first photometry signal and outputting the result as a second photometry signal and a selecting means selectively outputting these outputs. CONSTITUTION: The light beams of a part of a subject's picture reach a spot sensor 30 by a lens disposed in the central part of a separator lens 23, a output from the spot sensor 30 is electrically processed and inputted to a CPU 13. It obtains an average measured value with a prescribed algorithm. Moreover, the measured value of a spot is used without the average movement of the value of the spot sensor 30 for a long time. Then, the CPU 13 selects and outputs the outputs of the spot sensor 30 as the first photometry means and the average photometric value of the CPU 13 as the second photometry means. Thus, an average photometry part disposed in a conventional manner is made unnecessary.
