Publication number: 20220001844Abstract: A crane vehicle capable of preventing another vehicle from coming into contact with a tip end portion of a boom when entering an intersection includes a controller that detects an obstacle on a lateral side of a tip end portion of a boom by using left and right cameras when the vehicle enters an intersection or the like. When it is determined that a detected obstacle may come into contact with the tip end portion of the boom, the controller drives a brake device to stop a crane vehicle, and causes a speaker to output a warning sound. When it is determined that there is no risk of contact with the boom as the detected obstacle stops, or moves away from the crane vehicle by turning left or right, or passing an intersection, the controller releases the driving of the brake device to enable travelling of the crane vehicle.Type: ApplicationFiled: November 29, 2019Publication date: January 6, 2022Inventors: Satoshi Tanii, Kazuaki Tsuda

Patent number: 9540218Abstract: Provided is a work plan verification device capable of improving work efficiency of movement work of a suspension load. The work plan verification device determines whether an operator indicates a movement position of the suspension load on an image (A) displayed on a monitor (30). When a determination is made that the movement position is indicated, a mark is displayed on the movement position (B). Subsequently, a determination is made that the suspension load is suspended on a boom. When the determination is made that the suspension load is suspended, a load factor (C1) which is moving determination information allowing an operator to determine whether the suspension load can be moved to the movement position (B) is calculated, and the calculated load factor is displayed on the image (A).Type: GrantFiled: August 8, 2013Date of Patent: January 10, 2017Assignee: TADANO LTD.Inventors: Kazuya Tanizumi, Iwao Ishikawa, Kazuaki Tsuda, Shuji Fujiwara, Masayuki Munekiyo

Patent number: 7526435Abstract: An information offering system stores information on products and services along with attributes describing these products and services. Individual users are allowed to automatically register information on their products and services with the information offering system. By this method, the information offering system advertises products and services. Because the registration is done automatically by each offeror of a service or product, the efforts of a central administrator entering this information becomes unnecessary, thus making it possible to advertise more products and services efficiently.Type: GrantFiled: November 28, 1997Date of Patent: April 28, 2009Assignee: Fujitsu LimitedInventors: Hiroyuki Abe, Izumi Muraki, Seiji Yoshizawa, Akitoshi Kaneko, Kazuaki Tsuda

Patent number: 6251016Abstract: A lottery on a network like the Internet can be more easily attained by preventing impersonation and validating participation. In a preferred embodiment, the opportunity to participate in the lottery is a reward for viewing an advertisement. When the advertisement is viewed a lottery ticket issuing number is displayed as an image file on the browser of the user viewing the advertisement. The image file is sent from the server providing the lottery service to the browser with HTML source to display the number. The image file on the lottery server is deleted after being sent, so that if the user requests re-display of the ticket issuing number display, the number cannot be obtained. The lottery server maintains a database of date and time stamped. requests for lottery ticket issuing numbers to prevent multiple requests during a single session. The user is requested to input the number displayed by the browser to find out whether it is a winning number.Type: GrantFiled: October 31, 1997Date of Patent: June 26, 2001Assignee: Fujitsu LimitedInventors: Kazuaki Tsuda, Hiroyuki Abe, Izumi Muraki, Seiji Yoshizawa, Akitoshi Kaneko
