Title: Gate signal generating circuit for power conversion equipment
Inventor: YASUDA TAKASHI
IPC: H02M7/48
Filed: 1995-08-18
Abstract: PROBLEM TO BE SOLVED: To make it possible to perform a protective operation by masking gate signal commands to turn off all the elements when the non-conformity between a gate signal and an element ignition state has been detected even though ON/OFF of an element becomes impossible. SOLUTION: Non-conformity detection means 1 between gate signal and element ignition state can detect non-conformity between both signals by taking EXNOR of the gate signal and element ignition state of each element. An element ignition state logic anomaly detection means 2 has a logic as arm short-circuit where the element ignition states FGp and FGn become zero simultaneously, and this is considered as an ignition state logic anomaly occurrence signal. Gate signal logic anomaly detection means 3 checks tone logic of gate signal, and a logic that cannot be generated during normal time is defined as a gate signal logic anomaly generation signal.  Protective logic setting means 4 during a fault, can stop tone inverter equipment by masking the gate signal command in such a manner that both elements of positive and negative arms can be turned off when either a non-conformity signal, an element, ignition state logic abnormal occurrence signal or a gate signal logic abnormal occurrence signal has become zero.

Inventor: OSHIKAWA MASATO
IPC: E02B3/12
Filed: 1998-07-09
Abstract: PROBLEM TO BE SOLVED: To prevent a cover sheet from breaking owing to friction or the like of the sheet with conglomerates for backfill forming a slope face by laying a protection material on a part exposed from at least a water level on the slope face formed of the backfilling conglomerate for reclamation to make the slope face smooth and further, laying the cover sheet thereon. SOLUTION: Rubble 11 for a mound is laid on the bottom of water and caissons 12 are installed thereon at every appropriate distance and further, backfilling conglomerates 13 formed of crushed stones or the like are piled at the reclameratation side to form an embankment for reclameration. A protection material 3 formed of a net made of a hard material such as polyethylene is laid along the slope face 2 of the embankment. Then, a cover sheet 4 is laid thereon. The protection material 3 has meshes large enough to fit sharp corners of the conglomerates 13 therein and also thick enough not to protrude the corners out of the surface of the protection material 3. Accordingly, irregularity of the slope face 2 formed of backfilling conglomerates can be absorbed to form a flat face and the cover sheet 4 is placed so as not to come into contact with the conglomerates 13.  Hence, durability of the cover sheet 4 can be improved.

Title: Artificial stone material
Inventor: KAMIGAKI SANJI
IPC: B28C5/46
Filed: 1997-08-05
Abstract: PROBLEM TO BE SOLVED: To obtain an artificial stone material having uniform property, high strength, excellent weather resistance and durability and good appearance by kneading the mixture of an inorg. powder material, silica cement and water in vacuum and hardening. SOLUTION: Since the silica cement has a short hardening time and is hardened before the inorg. powder material uniformly dispersed by vacuum kneading again is aggregated according to the difference in the specific gravity, the artificial stone material with homogeneous properties can be produced without inhomogeneity of the inorg. powder material. As for the inorg. powder material, glass particles can be used. Since glass particles have reflection property for light and variety of colors, the obtd. artificial stone has excellent appearance, and also by processing glass particles into spheres, wounds to the stone can be prevented. By controlling the mixing ratio of the glass particles to the silica cement to 2:1 to 3:1, the obtd. artificial stone shows homogeneous properties with uniform dispersion of the glass particles.  The particle size of the glass particles is preferably 0.1 to 8 mm.

Title: Tape recorder with radio receiver
Inventor: KAWASE OSAMU
IPC: G11B31/00
Filed: 1982-11-30
Abstract: PURPOSE:To record a tape signal of reverse direction of one mechanism on a channel of other mechanism at the same time while radio and line input are recorded by providing a function switch and a 2-4 track changeover switch. CONSTITUTION:The 1st mechanism M1 is used exclusively for reproduction and the M2 is used for recording and reproduction. When the connection is made as the reproducing state and a tape is reproduced by the M1, a signal of heads ch1, ch2 is outputted to speakers 21, 22. Further, a reverse signal is extracted from ch3, ch4, but no sound is obtained. Since the 2-4 track recording changeover switches S1-1, S1-2 are selected to a fixed point (a), the signal is cut off at the output side of amplifiers 3, 4. Moreover, when the reproduction is done by the M2, it is the same as the case with the M1. Then, the recording mode of the circuit is selected. In case of dubbing from the M1 to the M2 with switches S2-1, S2-2 selected to a fixed point T, when the 2-4 track changeover switch is selected to the fixed point (a), 2-track dubbing is attained, and when the switch is selected to a position (b), reproducing heads ch3, ch4 being reverse direction as the reproducing heads ch1, ch2 for the forward direction of tape running at the M1 side are recorded to the M2 side at the same time.

Title: Correcting method for eccentricity of optical disk device
Inventor: YANAGI SHIGETOMO
IPC: G11B7/095
Filed: 1986-09-08
Abstract: PURPOSE:To contrive to prevent the variation with time of a reproduction signal caused by the eccentricity, to simplify a recording method and a reproducing method and to improve reliability by obtaining a servo signal in a rotary direction from a track servo signal. CONSTITUTION:A rotary direction servo control part 5 generates the servo signal in the rotary direction based on the track servo signal and servo-controls the beam movement of an optical head 2 in the rotary direction. Therefore, even if a special signal is not previously recorded in an optical disk 1, the servo signal in the rotary direction is obtained from the track servo signal to correct the eccentricity in the rotary direction. Thus the correction of the eccentricity in the rotary direction can be carried out without the reproduction signal and even in the optical disk 1 which is able to record, the recording and reproducing system considering the variation with time of the reproduction signal is not needed.

Title: Method for forming three-dimensional matter
Inventor: MATSUSHITA NAOHISA
IPC: B29K105/24
Filed: 1990-08-08
Abstract: PURPOSE:To easily form a three-dimensional matter, which necessitates the lamination of photo-setting resin having the surface area larger than that of the photo-setting resin to be laminated on the surface of set photo-setting resin, by a method wherein the set photo-setting resin is immersed in liquid, the specific gravity of which is larger than that of un-set photo-setting resin, so as to make tire surface of said set photo- setting resin flush with tire surface of said liquid. CONSTITUTION:For example, the surface area of a slice Sn, which is formed on a slice Sn-1 is larger than that of the slice Sn-1. However, since the specific gravity of liquid 20 is larger than that of photo-setting resin 10, the photo-setting resin 10, which is discharged from a resin discharge nozzle 17b and projects beyond the slice Sn-1 over the surface 20a of the liquid 20, is set through the irradiation of laser beams 18a as under the condition being floated on the surface 20a of the liquid in the same layer, which is continuous with the photo-setting resin 10 on the slice Sn-1 or under the condition that the photo-setting resin 20 turning into the slice Sn is discharged on the slice Sn-1 having the area as if larger than the area of the slice Sn. Accordingly, the conventional beam structural body becomes unnecessary and consequently a divergent crosssectional three-dimensional matter can easily be formed.
