Publication number: 20240152072Abstract: An image forming apparatus includes a mounting portion, an accommodating portion, a remaining toner amount detecting portion, a display portion, and a controller. In a supplying operation, the controller sets a threshold changing on the basis of a first output value before toner supply from the toner container to the accommodating portion. The controller discriminates whether or not toner in a certain amount or more is supplied to the accommodating portion by comparing the threshold with a second output value after the toner is supplied from the toner container to the accommodating portion. The threshold is a value between the first output value and a third output value in when the toner in a total amount accommodated in the toner container that has never been used is supplied to the accommodating portion before supply of the toner, and is closer to the third value than to the first value.Type: ApplicationFiled: November 6, 2023Publication date: May 9, 2024Inventors: MASAHIRO SUETSUGU, SHINICHI NISHIDA, TETSUSHI UNEME, TSUYOSHI OGAWA

Patent number: 5991689Abstract: In a navigation apparatus for a vehicle, a route is determined in an ordinary-road-preferential mode or a toll-road-preferential mode, and route guidance is provided based on the thus-determined route. When the vehicle deviates from the determined route, redetermination is conducted so as to obtain a new route based on which guidance is provided. For example, when the vehicle has deviated from a route determined in the ordinary-road-preferential mode in order to enter a toll road, the user operates a toll-road-preference ON touch button so to change the determination mode to the toll-road preferential mode, so that route redetermination is carried out in a state in which priority is given to toll roads. In the navigation apparatus, optimum interchanges of a special road are automatically searched, and a route that preferentially uses the special road is calculated.Type: GrantFiled: April 29, 1997Date of Patent: November 23, 1999Assignee: Aisin AW Co., Ltd.Inventors: Satoru Aito, Masahiro Suetsugu, Toyoji Hiyokawa, Kazuteru Maekawa, Takeshi Yanagikubo

Patent number: 5850618Abstract: Goals desired by a user are searched based on the search reference data that serve as reference for searching the goals, the order of priority of the goals is determined from a relationship between the data of goals and the data of a reference position, and the data of the thus determined order of priority are indicated. Even when the car is running, therefore, the user is allowed to easily select within a short time the goals that conform to his desire with reference to the order of priority. Accordingly, the user can devote himself to driving. When the goals are to be indicated, a map scale is so determined that the goals are indicated in a predetermined number or in a number not less than the predetermined number, and the goals are indicated on the map of this scale. Therefore, the scale of the map picture indicating the goals is automatically so adjusted, and can be easily discerned by the user. Therefore, the user is liberated from the need to manually adjust the reduced scale.Type: GrantFiled: December 28, 1995Date of Patent: December 15, 1998Assignee: Aisin AW Co., Ltd.Inventors: Masahiro Suetsugu, Kyoumi Morimoto, Hiroaki Kondo
