Title: Water-storing device for disaster
Inventor: MINAGAWA KATSUHIKO
IPC: E03B11/02
Filed: 1992-11-05
Abstract: PURPOSE:To provide a device whereby there is no necessity for replacing water therein periodically. CONSTITUTION:A water-storing tank 4 is connected to the midway part between water supply pipes 7, 11 led into a dwelling house 1, through detachable joints 8, 10. Since water in the water-storing tank 4 is replaced by new supply, by that amount whenever piped water is used, there is no necessity for periodically replacing the whole of the water therein. Furthermore, in the time of disaster, the water-storing tank 4 can be detached from the joints 8, 10 and can be moved to any place, and thus the water in the water-storing tank 4 can be used as drinking water or the like.

Title: Automatic steering control system
Inventor: YAMAMOTO SHIGEHIRO
IPC: B62D1/28
Filed: 1987-12-17
Abstract: PURPOSE:To attain automatic steering control excellent in stability and responsiveness over a wide traveling speed area by controlling a steering motor based on a deviation between a total feedback value and an objective value under a condition that the angular speed of a vehicle body does not exceed a preliminarily determined allowable value at the time of multiplying a steering angle by a fixed gain and feeding back the multiplied value. CONSTITUTION:When a steering command value (steering motor rotational speed command value) S is determined so that the vehicle body angular speed does not exceed the preliminarily determined allowable value, the rotating radius of the vehicle body corresponding to a deviation of a traveling course to be changed with time is determined within the range in which the angular speed omega does not exceed the allowable value ¦omegaal¦, a stability holding effect can be obtained even if the traveling speed is increased. Thereby, automatic steering control excellent in stability and responsiveness over the wide traveling speed area can be attained by selecting the feedback gain G.psi of the steering angle psi and the allowable value ¦omegaal¦ as proper values.

Title: Tone burst signal identification circuit and equipment in use for the same
Inventor: MIWA HIROHIDE
IPC: H04B1/16
Filed: 1988-12-19
Abstract: PURPOSE:To prevent the false output of a tone burst signal from being issued by comparing the signal strength of a narrow-band filter with a reference value equal to or larger than the output of the filter when no tone signal exists, and discriminating the tone signal from a noise based on the duration of a part where the signal strength exceeds the reference value. CONSTITUTION:A means to pass the narrow-band filter 1 and to decrease white and spike noise(SP.N.) after passing the filter and to increase input sensitivity by heightening an S/N, and a means to set the reference value (d) of a comparator 4 at a level to cut the white noise (W.N.) or a little higher and to increase the input sensitivity of the tone signal (SIG) are provided. Also, since the duration of the spike noise (SP.N.) exceeding the reference value (d) is short generally, a means to discriminate it from the tone signal (SIG) based on the duration is provided. In such a way, it is possible to prevent the false output from being issued as keeping high input sensitivity extending over a wide range from a weak electric field to a strong electric field.

Filed: 1994-12-22
Abstract: PURPOSE: To prevent water from being stayed at the lowermost part of boss part by forming an annular front drainage part from the front end face at the boss part to the inner circumferential face at a hole part, securing a yoke to a shroud while spacing the circumferential fringe thereof from the annular front drainage part, and integrating the outer circumferential part of rotor with the boss part. CONSTITUTION: A small quantity of water intrudes through a gap Z1 between the circumferential fringe 30A of a yoke 30 and the annular front drainage part 9 at the boss part 3 of a fan 2. The water passes between the yoke 30 and a rotor 5 and flows into the lowermost part of the annular front drainage part 9 at the boss part 3. Since the annular curved surface 11 at the annular front drainage part 9 has round cross-section, the majority of water flowing into the lowermost part of the annular front drainage part 9, upon stoppage of the fan 2, does not stay on the annular curved surface 11 at the annular front drainage part 9 but advances onto an annular inclination surface 10 while resisting against the surface tension and then it is discharged to the outside. A part of the water is introduced into a groove 7 and discharged to the outside.

Title: Communication controller and data communication system
Inventor: OKADA KAZUNORI
IPC: G06F13/00
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To provide a communication controller consisting of a microcomputer that is suitable to form a 1-to-multi data communication system. SOLUTION: A microcomputer, that is provided for an electronic device connecting with a transmission line for serial data communication, receives transmission request data from other device and sends reply data with respect to the transmission request data when a consecutive time of a state not receiving data from the transmission line reaches a predetermined reply start time. The microcomputer discriminates reception of data sent from devices other than its own device through the reception interrupt processing executed when data are received by its own communication section (S130: NO). Then, the microcomputer sets a time information denoting a reply start time into its own timer section (S140). When the timer section generates a timer interrupt processing request, the microcomputer conducts transmission of reply data through the timer interrupt processing.  Thus, the reply data are transmitted in an accurate timing without increasing the processing load.
