Title: Production of casting mold
Inventor: WATANABE TEISHIRO
IPC: B22C9/04
Filed: 1984-07-28
Abstract: PURPOSE:To obtain a casting mold which is free from the disadvantages by foamed polystyrene in a full mold method by manufacturing the casting mold by using a foamed molding of a high-polymer material then shrinking and solidifying the foamed molding by hot air and removing the molding from the mold inside. CONSTITUTION:Molding sand is molded by using the pattern of, for example, the foamed polystyrene molding and thereafter the hot air kept at 100-200 deg.C is fed into the casting mold. The above-described pattern is shrunk and solidified and the residues of the shrunk solid produced therein are mechanically or manually removed from the mold inside. A molten metal is cast into the cavity in the mold formed in such a manner, by which the product casting is manufactured. Problems such as the generation of black smoke and fire column by the gas generated from the PE in the full mold method and the generation of blow back of the molten metal by the back flow of the generated gas in a runner are thus eliminated. There is also an advantage in that the low expansion type polystyrene can be used.

Title: Diagnosing system for memory backup function
Inventor: FURUBAYASHI SHOSAKU
IPC: G06F12/16
Filed: 1989-06-19
Abstract: PURPOSE:To judge whether the backup function diagnosis itself of a memory is effective or not also by providing a means which confirms whether a main power source is turned off for enough time to erase data of the memory or not. CONSTITUTION:Main power source voltage check data is written in a non- backup area 33 and a main power source 34 is turned off, and the main power source 34 is turned on again after a certain time to read out data in this area 33. The backup function diagnosis is ineffective if read data and written main power source voltage check data coincide with each other in their checking: but otherwise, the backup function diagnosis is effective. Thus, it is judged whether the diagnosis itself of the backup function of a memory 31 is effective or not.

IPC: A01B69/00
Filed: 1992-06-17
Abstract: PURPOSE:To stably detect the border between unmown and a mown place without being affected by disturbance by correcting lawn presence information into lawn absence information unless other lawn presence information is present nearby the position of the lawn presence information in currently sampled lawn presence/absence information. CONSTITUTION:A border deciding means 100 decides the border between the unmown place and mown place by sampling pieces of information of means 22 and 23 which detect whether or not there is the lawn at specific intervals in the breadth direction of a machine body. The border deciding means 100 corrects the lawn presence information into the lawn absence information unless there is other lawn presence information nearby the lawn presence information in the currently sampled lawn presence/absence information. Further, the border deciding means 100 ORs the lawn presence information with the current corrected detection information and last and several precedent pieces of lawn absence information. Then the border deciding means 100 decides the border according to the information obtained by the OR operation. Consequently. the influence of the disturbance is precluded.

Title: Antenna controller
Inventor: YOSHINO YASUNORI
IPC: G05D3/00
Filed: 1992-06-17
Abstract: PURPOSE:To shorten the searching time of a satellite and also to ensure the stable reception with an antenna by compensating the rotational angular speed of an angular speed sensor in the compass direction of a mobile object. CONSTITUTION:In an initial state, a switch 32 of an antenna controller main body 3 is connected to an angular speed sensor 4 together with a switch 33 connected to the search signal side respectively. The signal obtained with inversion of polarity of the angular speed of a mobile object is added to a search signal for compensation and elimination of the angular speed of the mobile object. Thus a satellite is searched at a fixed speed that can search a real satellite, and the satellite is automatically tracked by the signal of a switching transmitter/receiver 2. At the same time, the timer used for tracking of an open loop is initialized. The timer counts the time when the open loop is tracked based on the rotational information on the azimuth direction given from the sensor 4 in a non-catching state of satellite. Therefore the satellite is searched at a fixed speed after the rotational angle of the mobile object is compensated. Thus it is possible to ensure the stable reception and to shorten the searching time of the satellite.

Title: Rising and falling dam made of flexible film
Inventor: SHIBATA YUTAKA
IPC: E02B7/20
Filed: 1981-10-02
Abstract: PURPOSE:To exactly prevent the overtopping vibration of a dam by a method in which the spring constant of the circumferential material of the torso portion of a flexible film bag constituting the dam is obtained on the basis of the height of the dam and the depth and internal pressure of overtopping water, and the dam is operated under a condition that the spring constant is kept larger than a fixed value. CONSTITUTION:A flexible film bag 1 consistuting a dam is attached to a river bed 4 across a river. In this case, where the depth (h) of overtopping water is 0.4 1.2 times the height H of the dam and the internal pressure of the overtopping water is within a range of 1.0 3.0 times the height H of the dam, a film material having a spring constant greater than that of the film material in the circumferential direction of the torso of the dam, obtained from Figure, is used. For example, when H=1m, h=0.5m, and P=2.0mAq, h1H=0.5 and P/H=2.0 result, and the spring constant K becomes 50XH<2>=50kg/2.5cm. Thus, when the film material in the circumferential direction of the torso of the dam has a spring constant greater than said value K, the vibration of the dam can be completely prevented.

Title: Magnetic recording and reproducing device
Inventor: HIRATA SHUJI
IPC: G11B5/027
Filed: 1989-06-20
Abstract: PURPOSE:To prevent vertical synchronization from being disturbed in a video output signal after clamping due to noise by clamping the noise of a reproduction video signal after demodulation to a pedestal level and clamping a vertical synchronization part of a reproduced video signal to a SYNC tip level. CONSTITUTION:When a signal missing takes place for a period longer than a prescribed period in a reproduction signal, a dropout compensation circuit 3 detects the signal missing part. Then noise of a signal missing part in the reproduction video signal is clamped to a pedestal level by a clamp circuit 9 after demodulation, while the vertical synchronization part of the reproduced video signal is clamped to a SYNC tip level by a pseudo vertical synchronizing signal of a pseudo vertical synchronizing signal generating circuit 10. Then an inconvenience that the vertical synchronization part is not clamped to the pedestal level similarly to noise and the noise is misdiscriminated with the vertical synchronizing signal is prevented. Then the vertical synchronization in the video output signal after clamping due to noise is not disturbed.
