Title: On-vehicle automatic preset tuner
Inventor: HONDA TSUTOMU
IPC: H04B1/06
Filed: 1990-05-28
Abstract: PURPOSE:To realize complete automatization of preset tuner by selecting a reception area corresponding to a current location automatically based on a range data obtained by a GPS (Global Positioning System) receiver and presetting a broadcast station automatically in response to the selected reception area. CONSTITUTION:When a current location data of a vehicle is sent from a GPS receiver A, a reception area selection means B selects a reception area corresponding to the current location data of the vehicle from a table storage means C and reads a data of a preset station designated in the selected reception area and sends it to a preset means D. The preset means D presets each station to a tuner section E based on a sent data of each preset data. Thus, even when the reception area of a radio broadcast is changed due to a long distance drive or the like and the station having been received so far is disabled of reception, a new broadcast station is preset automatically corresponding to the current location data of the vehicle. Thus, a completely automatic on-vehicle automatic preset tuner is realized.

IPC: G11B15/02
Filed: 1986-06-11
Abstract: PURPOSE:To reduce the processing time for an input command by optimizing the input command in the mode for stacking and executing the transition of the mode according to the stack information. CONSTITUTION:The mode stack is formed in a RAM of a microcomputer constituting a controller 2 and in depressing an operation key of an input means 3, the mode stack is processed by the controller 2 and the result of processing is fed to a control section 1, which is controlled to attain a prescribed operation mode. The stack system as above is adopted and the levels of the mode stack are formed as plural stages. In inputting the mode, the mode is stored in order in the mode stack, the stored mode is subject to optimization to eliminate a meaningless mode from the mode stack and the modes remained in the mode stack are executed in the older order. Thus, the object mode is transited in a shortest time from the input mode at that point of time.

Title: Long cross flow fan
Inventor: SAKAI KOJI
IPC: F04D29/04
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To provide a long cross flow fan which can achieve air volume increase and light weight by omitting a passing through shaft from an impeller thereof. SOLUTION: One end of a shaft 5 is fixed to the center of rotation plane of a flange 11 perpendicular with respect to the plane and extended threrethrough. The flange 11 comprises an annular disk 13 to which vanes of one of adjacent impellers are fixed approximately cylindrically and a bracket 12 to which the annular disk 13 is fixed concentrically. The middle part of the shaft 5 is journaled through a rotary bearing 6 in an intermediate plate 9 which is fixed to a casing. A joint 7 is fixed to the other end of the shaft 5. An annular disk 22 and an annular disk 23 to which vanes of the other impeller are fixed are arranged integrally to the joint 7 through an elastic body 21.  Since a passing through shaft is omitted from the impeller, an air flow is not disturbed, so an air flow amount can be increased, and thereby it is possible to reduce the diameter of the impeller and to decrease the number of revolutions. This also contributes to save energy and to reduce noise. Furthermore, due to the elastic body arranged in the flange of the impeller, an abnormal change of weight balance can be absorbed, and thus the impeller can be rotated stably.

Title: Position detector
Inventor: MISAO IKUO
IPC: G06F3/03
Filed: 1984-06-30
Abstract: PURPOSE:To reduce effectively the level difference of signal voltage obtained from a voltage detecting means by setting a larger number of the 2nd thin strand conductors to which the prescribed voltage is applied at a time than the number of the similar 1st thin strand conductors. CONSTITUTION:The voltage is supplied successively to the thin strand conductors X1-Xn arrayed in the X direction of a position detecting plate 10 and to the thin strand conductors Y1-Ym arrayed in the Y direction on the surface having a larger distance from a voltage detecting means 30 set on the plate 10 than the surface where said conductors X1-Xn are arrayed. In such a case, the position of the means 30 on the plate 10 is detected based on the signal voltage obtained from the means 30. Here the number of conductors Y to which the prescribed voltage is applied at a time is larger than the number of conductors X to which the prescribed voltage is applied at a time. Thus an equal position detecting state is secured between both array directions of conductors X and Y. In such a way, the detection errors are considerably reduced.

Title: Waiting time processing method for mobile communication terminal
Inventor: USAMI HIDEAKI
IPC: H04W52/02
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption by executing control channel monitoring in a background where the other base station is searched only when a terminal detects movement. SOLUTION: When the reception level of a control channel from a base station BS in a place where a user stays over a long period of time, e.g. the user's home, that is, when it does not satisfy a background monitor start level, a terminal PS periodically executes control channel monitoring. Thus, power consumption is increased. A function for monitoring the reception level of the control channel from the base station and judging that the mobile communication terminal PS has moved when the fluctuation of the reception level reaches a prescribed value is provided for the mobile communication terminal PS. Only when the terminal PS detects the movement with the fluctuation of the reception level, a control channel monitor function in the background is validated.  Thus, the power consumption of the PS when it stays in a place where the reception level of the control channel from the base station BS is weak is reduced.
